Chapter 1: Introduction and Research Design 1.1. Introduction Concept Islamic Banking or Islamic Finance or Sharia-compliant Finance is banking or financing activity that complies with sharia (Islamic law) and its practical application through the development of Islamic economics. Some of the modes of Islamic banking/finance include Mudarabah (Profit sharing and loss bearing), Wadiah (Safekeeping), (Joint Venture), Murabahah (Cost plus), and Ijara (Leasing). Sharia prohibits Riba defined as interest paid on all loans of money (although some Muslims dispute whether there is a consensus that interest is equivalent to Riba). Investment in businesses that provide goods or services considered contrary to Islamic principles (e.g. pork or alcohol) is also haraam ("sinful and prohibited"). Moreover, what you give in usury (riba ), that it may increase upon the people's wealth, increases not with God; (Quran 30:39) Other Medinan verses are: for their taking usury (riba), that they were prohibited, (Surah An-Nisaa Quran 4:161) O believers, devour not usury (riba), doubled and redoubled, and fear you God; haply so you will prosper. (Surah Al-i-'Imran Quran 3:129-130) Capital structure is particular distribution of equity and debt that makes up the finance of the institution. Capital structure is the most effective parameter to check the performance and valuation of financial institutions. The primary object of the financial managers should be to increase the shareholder’s wealth is decided the best way source of fund for financial institutions. Capital structure theory was introduced first by Modigliani and Miller in 1958 who examined the firm’s value change though changing its capital structure (Modigliani and Miller 1958). After this theory many of papers publish to investigate and try to find the impact of capital structure on conventional bank and corporate performance. Few papers found on influence of capital structure on financial Islamic Bank performance. So the purpose of this survey we checked the effect of capital structure is negative or positive on Islamic banks performance. (Kajananthan 2012)The decision of the capital structure is very essential because such type of decisions are directly influence on the performance of the firms. The victorious selection and usage of funding or capital is one of the major key component of the organization The firm’s financial performance is not based on the capital structure but on high-quality performance of the organization is created on the strategic knowledge by the management. Also achieved by the good governance

(Ross, Westerfield et al. 2008, Bodie 2009, Brealey, Myers et al. 2012). To gain a return on equity, financial institutes can make use of a mixture of methods and strategies. One strategy is use of capital structure. The relationship among Capital structure and Return on Equity is definitely major significance to all firms. The decision of capital structure is particularly essential to banks because they are profound to fluctuate in financial Leverage due to their low rank of owner’s equity to entire assets. The decision of capital structure is very is very important for regulators, mangers and also important for shareholders of the firm. Banks are mandatory to retain a minimum ratio of capital by rating agencies and regulatory authorities. One of the major objectives of financial managers must deem to maximize shareholders value by using the finest mixture of financial capital designed for the corporation. Furthermore, financing evaluations for the investment is the vital obligations of organization in assurance of the greatest blend of money related assets, and an extra purpose of financial chief or head is to take this type of assessments that helpful to achieve the firm value and also decide to invest their resources. Moreover, how to funding the assets of the company and also how much equity and debt generate to financed their assets, because this’ll effect on decision of the corporation’s (Yahyazadehfar, Shams et al. 2010). Two main sources are on hand for firms willing to generate funds to perform their activities. In which the first one is internal source of fund and second is external source of fund. When the firm raises funds within the enterprise is known as internal source of funds that is commonly retain earning. To enhance their activities firms look outside to generate more funds to achieve a level of performance. When firms use take from external sources in shape of funds or loans in response it leads to increase the number of co-owners in the business. Islamic banking system has been explained as banking in harmony among components with the value and philosophy structure of Islam, as well the rules of management and law of risk is set by Islamic Shariah. Islamic banking system is against to interest base system because it is banned in the Shariah of Islam. The system of Islamic banking is also avoiding the immoral practices to achieve the aims of an economy. Islamic Shariah does not make illegal capital gains. Banking system of Islam is based on sharing of risk, and observes to management asset to generate the profit. According to history of Pakistan financial system of Islamic banking system was introduced in 1977-78. In 1980s, the council of Islamic ideology presents detail information about Islamic rules regarding the economy. The overall financial system was rapidly shifted to interest free banking but unfortunately Islamic banking system was failed due to inadequacy of human resource. In 1999s another approach used for Islamic banking system that approach was to set up an Islamic banking services in the conventional banks. Islamic banks deal in different type of investing modes like MURABAHA, IJARAH , IJARAH-WAL-IQTINA, MUSAWAMAH, ISTISNA, MUSHARAKAH and MUDARABAH . Deposits and assets of Islamic banks were recorded at Rs.1564 billion and Rs.1885 billion in that order by end March, 2017. In overall banking industry the market share of deposits of Islamic banking was 11.7 percent and the assets market share of Islamic banking was 13.2 percent at the end of March, 2017. The system of Islamic banking is containing twenty-one (21) Islamic bank associations in which five (5) purely Islamic banks as well as conventional banks having sixteen (16) branches. Total Islamic branches was recorded 2,317 that operating crossways 116 districts of Pakistan. There are 1,239 Islamic banking windows controlled by conventional banks at the end March, 2017. The performance of a firm needs to do with how efficiently and effectively it can' accomplish the set objectives which might be operational or financially. The money related performance of a firm identifies with its thought process to augment benefit both to investors and on resources (Chakravarthy 1986) while the operational execution worries with development and extensions in relations to deals and 'market esteem (Chrisman, Bauerschmidt et al. 1998). Since capital is used by organization to accomplish the associations define objectives, and execution is said to be the destinations so set, structure of capital and organizations execution are in this way anticipated that would be relatively related and affected each other. (David and Olorunfemi 2010), capital structure is the blend of equity and debt to finance the business. It is utilized to speak to the proportionate connection amongst equity and debt in corporate firms' funds. Along these lines, in this unique circumstance, the blend of debt and equity in an organizations' capital structure. This is in accordance with the definition (Chou and Chou 2007) as a blend of equity and debt financing of a firm. An ideal structure of capital is the great equity/obligation proportion of a firm, which limits to financing cost and expands the estimation of the organization.(Nikoo 2015) utilizing the information of 17 banks from the duration of 2009 to 2014 explained the connection among the financial performance and structure of capital that is directly relate with each other.

The decision of capital structure is play a vital role in managerial decision because it manipulates the risk and shareholder return. The decision of Capital structure is also influence on the market share of the firms. The companies have to decide its all plan regarding structure of capital at the point of starter. Afterward, whenever they have raised the funds the assessment of capital structure is involved. The requirement for generating more funds that lead to a new structure of capital that needs a critical study (Birru 2016). (Myers 2001) stated that which there was not exist any common study or rule of thumb on choice of debt and equity but point to be noted that still there is not any specific theory to explain the accurate structure of the equity and debt mixture. But some theories explore some mixture of capital structure.

Be that as it may, the author finds out inverse relationship between of LTDTA with ROE. The fundamental disadvantage of this research paper was that they utilized just a single variable return on equity to determine the performance. (Kajananthan 2012) an investigation that is identified with Sri Lankan listed firms was done in 2013 by who checked the link between capital structure and firms performance of 25 companies utilizing the information covering the times of 2008-2012. Net benefit, gross profit, returns on assets and return on equity, were utilized as the measures of firm performance while debt assets ratio and debt equity ratio were utilized as the measures of capital structure. The statistical tests were utilized, where, the outcomes demonstrate that net profit, gross profit, return on assets, return on equity, are not significant associated with debt equity ratio. Also show a significant connection between capital structure on gross profit and return on equity. (Komnenic and Pokrajčić 2012) conducted a study and empirically describe connection between intellectual capital and organization performance. In this paper the Human and structural capital efficiency are used as dependent variables. Return on equity and return on asset is used as independent variable and capital employed efficiency were treated as control variable. To analysis the data regression statically tool is used.

This paper also explained that there is no impact on the performance of the firms by their high growth or low growth firms. (Salehi and Biglar 2009) conducted a research on this issue weather there is relation between capital structure and financial performance of the firms. They use three variables to explain the capital structure and five measures to clarify the financial performance of the firms. The sample size is 117 firms those listed on stock exchange of Tehran and the data is taken from 2002 to 2007.the findings of this study showed that the structure of capital of Tehran firma have affect the financial performance of the firms.

In this research paper found that negative critical effect of the total debt and short term debt on financial performance of estimated by ROA, yet there is no huge link found between the long term debts and estimated of the financial performance. He is likewise proposed not critical impact of debt (STD, TD& LTD) on the financial performance of estimated by net overall revenue and Return on assets. In this paper found the outcomes firm size control variable no significant impact on firm performance. In this research used the least squares regression statistical tool to determine performance of organization. We conduct the study by (Shafique, Faheem et al. 2012) who examines the Global financial affect the conventional banking system in all worlds. Islamic financial method performance is improved than conventional method of banking in the worldwide financial crises. During the IFN (interest free nature) of the Islamic financially structure the risk is less than of the conventionally banking system. In this research the order of Islamic banking system increases the WW (Western world) during the international financially structure. In this study test the validity of view that in the worldwide financial crises, system of Islamic bank also constant, then the conventional banking system. In this paper explains that the Islam is many additional, the prevention of the Zakah & Riba, but broad method accomplishes the society’s necessities. But the Islam point out on needs & peoples, instead of production. In the sector of Islamic banking one investigated by (Berger and Di Patti 2006) clearly inspected the new procedure for test the impact of capital structure performance on banks. In this research used the SEM (Simultaneous Equation Model) for the reserve causality by performance to capital. The profit efficiency used of firm performance to analysis agency cost & controlled the ownership structure. This research used the data 1990 to 1995, on 7320 US banks. The finding shows consistency with results & agency theory. (Berger and Di Patti 2006) controlled concurrent predisposition and they utilized averages variables over of the period rather Panel information. These studies used the panel data & increase the sample size & also increase the estimators & give more power of statistics.

Chapter 3. Data analysis & Methodology / Empirical Result 3.1 Data collection & Methodology The target population of this survey consists of Islamic banks of Pakistan which is listed at Pakistan stock exchange at under banking company ordinance 1962. We select Islamic banks because the object of this paper is to examine the link among the capital structure and financial performance of Islamic banks of Pakistan. The sample size of this study contains five Islamic banks including Meezan Bank Limited, Bank Alflah Limited, Dubai Islamic Bank, Bank Islamic and Al Baraqa Bank. The information regarding current study is obtained from the annual reports of the banks. These financial reports are accessible on the banks websites and also the website of Pakistan stock exchange. . Return on asset, return on equity, profit margin and earnings per share is used to measure the degree of financial performance of the banks that is endogenous variables. Capital ratio, debt ratio, debt to equity ratio and debt to capital ratio is treated as exogenous variables. For this purpose we use descriptive analysis to investigate the collection of data. Regression and correlation is also use to determine the link among structure of capital and Islamic banks financial performance of Pakistan. 3.2. Variables There are following in which return on asset, return on equity, profit margin and earnings per share is used to measure the degree of financial performance of the banks that is endogenous variables. Capital ratio, debt ratio, debt to equity ratio and debt to capital ratio is treated as exogenous variables. 3.2.1 Endogenous variables These are the following variables that considered as endogenous in which return on asset, return on equity, profit margin and earnings per share. Return on asset (ROA): Return on asset (ROA) is a money related proportion that exhibits the level of advantage an association gets in association with its asset. It is typically described as net income divided by total firm asset. Net income is derived from the income statement of the firm and is suitable after charges (Ramadan and Ramadan 2015, Rouf and Abdur 2015, Siddik, Kabiraj et al. 2017).A normally utilized measure of bank implementation is ROA, that provide a picture of how compelling the administration of the bank is in producing income with its accessible resources. Return on asset is also used by these researchers as an indicator of financial performance: (Salawu 2009, Gill, Biger et al. 2011, Chen, Wang et al. 2012, Fosu 2013). Return on equity (ROE): Return on equity (ROE) is the total of profit return as apportion of owners’ equity. Return on equity explain the organization’s profitability by disclose how a lot earning is produce with the capital that is provided by the shareholders of the firm (Pouraghajan, Malekian et al. 2012, Salim and Yadav 2012, Akeem, Terer et al. 2014).Return on equity is a great measure of the performance of the banks. Return on equity is the measure to check that how management of the firm use the funds of owner. Return on equity is used by these researcher as financial performance indicator (Abor 2005, Amjed 2007). Both return on equity and return on asset is used by some writers as measure the financial performance of the firm (Pratheepkanth 2011, Saeedi and Mahmoodi 2011, Abu-Rub 2012). Profit margin (PM): Profit margin is a ratio that indicate the profit of the organization it is demonstrate in shape of percentage and explain that how much company earn against every dollar of sale. It is calculated as income after interest and tax over by sale or net income over by sale. (Gibson, 2013) Profit margin (PM) is a ratio that indicates the net profit earned by the firm with each financial part of sales generated or produced by relating the net sales and net profit of the firm. (Bodie, Merton et al. 2009) Such type of ratio is used by the outside or peripheral users of financial and accounting like: creditor of the firms or investors to judge that how a company efficiently can transform revenue or sale into net profit Earnings per share (EPS): Earnings per share are the element of the profit of the firm that pays to the outstanding shares holders. It is use as meter of the financial performance.(Abu-Rub 2012) contended that Earning per Share is the essential estimation of corporate performance and increase in earnings per share its mean the performance is also boosting up. Earnings per share are use as
6 J. Basic. Appl. Sci. Res. , 9(3)1-13, 2019
indicator of performance of the firm it is computed by dividing the income after interest and tax over the number of outstanding shares. Earnings per share are obtained as: EPS= Net profit-dividends on preferred stock / average outstanding shares 3.2.2. Exogenous variables In this paper to explained the connection among capital structure and financial performance of Islamic banking of Pakistan in which Capital ratio (CR), debt ratio (DR), debt to equity ratio and debt to capital ratio is treated as exogenous variables. Capital ratio (CR): Capital ratio explains as book value of the total owners’ equity or shareholder equity over total asset. Basically it explains the total value of owner funds against total asset of the firms it is called the equity to total asset ratio. Debt ratio (DR): To measure the capital structure the debt ratio is also indicator that use by researchers. Debt ratio is a indicator of financial ratio that measure the level of the organization leverage. The ratio of debt is demonstrated as the ratio of debt and total equity its shows as a percentage. It can be translated as enhance of an firm's advantages that are fund from debt. Debt to equity ratio (DER): Debt to equity ratio is a ratio that speaks about finance that demonstrates the comparative point the value of investors and debt used to return back a firm advantage. It is closely interlinking the leverage it is also known as gearing or risk. It is explained as percentage that shows the firm how much have debt and what the value of our equity. Total debt to total equity is a measure of structure of capital that is also influence the financial report and performance of banks Debt to capital ratio (DCR): An estimation of an organization's money related use, computed as the organization's obligation isolated by its aggregate capital. Obligation incorporates all here and now and long hauls commitments. Add up to capital incorporates the organization's obligation and investors' value, which incorporates normal stock, favored stock, minority premium and net debt.
To determine the capital structure there are following variable debt to equity and total debt over total asset used by these researcher (Berger and Di Patti 2006, Manos, Murinde et al. 2007, Shoaib 2010, Papa and Speciale 2011, Bei and Wijewardana 2012, Fosu 2013, Park and Jang 2013, Taani 2013, Chechet and Olayiwola 2014, Kipesha and James 2014).

Chapter 4. Conclusion This research paper investigates the affiliation among capital structure and financial performance of Islamic banking of Pakistan. The decision of capital structure is important for the banks because its plays a vital function in the financial performance of Islamic banks. We collect data of following Islamic banks in which including Meezan Bank Limited, Bank Alflah Limited, Dubai Islamic Bank, Bank Islamic and Al Baraqa Bank from the time period of 2007 to 2017. For the purpose of data collecting we use annual reports of the banks that are available on the banks official sites and web site of the state bank of the Pakistan. To take analysis we use a five banks data as a sample and use different statistical techniques to achieve the purpose of this study. We use descriptive analysis that explains the mean, median, maximum, minimum and standard error values of the variables. Regression analysis is used to determine and point out the significance level of the variable and explain that how much a variable is related to other variable and how much an independent variable depends on the other depended variable. There are four variables in which return on asset, return on equity, profit margin and earnings per share is apply to determine the degree of financial performance of Islamic banks that is endogenous variables. Capital ratio (CR), debt ratio (DR) debt to capital ratio (DCR), and debt to equity ratio (DER) is treated as exogenous variables. Correlations technique is also used to explain the relation of all variable with other variables. According to the results of this study return on asset is positively significant with return on equity and profit margin at the level of 5%, *** significance level. Earnings per share (EPS) is also significant at the significance level of 5% *** level of significance. Capital ratio (CR), debt ratio (DR), debt to equity ratio (DER) and debt to capital ratio (DCR) are insignificantly related with return on asset (ROA). the

Received: February 4, 2019 Accepted: April 30, 2019 ABSTRACT
Indonesia has a wealth of traditional vernacular building architecture that is scattered with various types of shapes. The diversity is estimated to have strong elements that show a red thread in the form of architectonic patterns. Through this study, it is expected that architectonic patterns may be recognized based on the diversity and distinctiveness of the designs displayed so that their potential can be determined for both the present and the future. Many descriptions of architectural designs encountered in Indonesia today with their specific form give the impression of being detached from their specific 'place' and 'collective memory' owned by Indonesia. This study aims to explain the architecturally strong elements of traditional Indonesian buildings through typo- morphology. Based on architectonic comparative studies, various elements of traditional Indonesian residential architecture are identified with strong elements including the concepts of Ornamental, Symbiosis of Outer, Transitional, and Inner Space, Breathing Walls, Roof Domination, Non-Rigid Structures, and the like. These elements have the potential to be further developed reflecting the progress being made in this era (progressive- visionary), but still built based on the values of locality that refer to Indonesia's noble culture. KEYWORDS : Architectonic, Traditional, Indonesian, Vernacular, Typo-morphology
1. INTRODUCTION
Indonesia has a rich variety of traditional architecture in abundant vernacular forms. This diversity of forms shows the existence of a strong architectural tradition in Indonesia established since the past. The architectural tradition is manifested in the ability to process forms through adequate creativity. The architectural wealth in the present can be presented as a local historical prototype, given the current globalization capable of penetrating territorial boundaries. This local historical prototype can enrich local identity. The effort to represent identity through localism is one of the responses to the phenomenon of globalization. Representations originating from past traditions and localities can be a reference in generating identity. Identity cannot be presented instantly but through repeated regular and persistent stages. Knowledge of local traditional architecture must be consistently preserved [1] Learning about and preserving the vernacular-traditional architecture do not mean being trapped in romanticism in the sense of glorifying the past but must be able to be linked to its continuity with the future. Preservation should be understood not only in reference to the conservation of the object itself but also the values, wisdom, and elements that can be transformed for the present and the future. Changes in human culture are simply unavoidable, so that architecture as a container will follow suit in making adjustments. Architecture can be an object that is archaeological in keeping a low profile but can also be transformative in that it dynamically inherits its elements for the future. Today’s postmodernism [2] provides an opportunity for freedom of excavation of sources of design inspiration that present an identity or character, which is derived from the spirit of the past, locality and regionalism. Postmodernism offers challenges (plurality) as well as opportunities to pay attention to the other side posed by the reality of its society. This study is an architectonic exploration related to traditional vernacular residential architecture in the Indonesia. Basically, architectural excavation can be very broad, so this study is only one model and is limited to the problem of representation of form and space. The approach taken is through typo-morphology. The exploration of sources that refer to locality can also be linked to climate issue, such as Indonesia with its tropicality. Architecture in the tropics basically has different characteristics from non-tropical regions. However, countries/continents with a tropical climate include not only Indonesia, but also Africa and Latin America, so that the tropical element is “insufficient” to represent the character of locality [1] The understanding of architectonic in this study is related to the properties and principles of architecture or design such as the problem of space-form including the tectonics of its formation. In this study, the architectural principles of traditional Indonesian architecture will be examined in the form of architectonic patterns. These principles concern the problem of form and space. Thus the potential is expected to be recognized so that it may be transformed in the era of the present and future. Through transformation it is possible for representations

The transformation process involves changing forms and meaning, which can be accomplished through borrowing. The Strategy of Borrowing [3] is a transformational approach through formally borrowing a form derived from paintings, sculptures, objects and other artifacts. By way of this process, two and three dimensional characters are studied in an attempt to interpret their application and possibilities. This transformation is a "pictorial transferring" (image transfer) that can also be a "pictorial metaphor" (image metaphor). To give an example, a form of Javanese house is used as the basis for transformation in designing a hotel, or other public buildings. The reuse of old architecture into new buildings seems to be in line with the spirit of the developing era, namely that of postmodernism. Postmodernism, which is seen as critical of modernism, is essentially promoting the concept of double coding, which combines cross-coding values, namely old-new, global-local, and so forth. Therefore, postmodernism as a basis for developing ideas through the transformation of architectural forms enables efforts to recontextualize past values such as the ones relating to place and spirit of place, local wisdom, and the like. History can be understood not only through the past but also through the history of the present. In his discussion of the present, the French philosopher and historian of ideas Michel Foucault mentions [4] that historical studies must always be related to the present. History is not understood to have come to a grinding halt in the past but is dynamic, especially with regard to its impact on the present.
2. METHODS
This research has been conducted in a descriptive argumentative way to explain in architectural terms Indonesian traditional buildings through typo-morphology. Understanding of typologies or architectural typo- morphology studies can be interpreted as an assessment of architectural types by taking into account the forming elements (structure/elements/ components) and their composition. The emphasis of typo-morphological study is more on the analysis of the forming elements/components/structure of in a type [5]. This approach can be used to examine the extent to which representations of types of enshrined design elements are used in the various contexts of different eras. In addition, typo-morphological studies can be used to identify correlations of architectural forms, properties, and rules[6]. The nature or character can be associated with aesthetic principles such as unity, balance, point of interest, hierarchical symmetry, rhythm/repetition, tone, the principle of emphasis, texture, the solid-void contrast, and scale-proportions [7] [8]. Thus it is expected that in a holistic manner, it can be discerned that the strong architectonic elements contained in its design include space and form. By understanding the strong elements, it is expected that these potentials can be analyzed for building designs in the present. Not all locations can be reached through field surveys due to limitations, so they will be selected by purposive sampling. Assessments and comparisons will be made of the floor plan and appearance, and place the following components in it such as facades and ornaments. In general the steps of the research carried out are: Comparing the traditional vernacular building design to find the correlation between the design elements of the building's architectural type through a typo- morphological study. The variables used are architectural elements, namely spatial plans and layouts, figures, decorative ornamentations, and the technology-construction used [9][10]. Make an interpretation and an analysis based on consideration of these rules to look for the potential that can be transformed in the fixed framework referring to the characteristic forms of Indonesian architecture. The results of this study are expected to enrich the understanding of a red thread or strong element in the architectonic patterns.
3. RESULTS AND DISCUSSION
3.1 Symbiosis of Outer-Transition-Inner Space The meaning of outer-transition-inner Space are familiar in East Architecture [11]. Recognizing space in traditional residential architecture in Indonesia can be understood not only in the form of internal space but also involves outside space and space between outer space and inner space (transitional space). Outer space is known as the yard in the form of open space as a place of public interaction. Transitional or intermediate space can be connected with terraces/verandah such as in Java or falling under the architecture outside Java. Inner Space can be dialogue with the main building which is the core, like the palaces on Java, the Banua in Toraja, Jabu among the Bataknese, Betang among the Dayak tribe, and so on. These spaces can be understood as a unified whole space between inner space, transition, and outer space. This idea illustrates the continuity between space in the form of permeable, flowing spaces, through semi-open terraces. The outer spaces between the masses of the building are not considered to be independent but designed continuous with transitional (semi-open) space and inner space. The idea of the continuity of the space is strongly influenced by the surrounding tropical nature. Tropical nature allows outdoor activities throughout the year. Thus the site layout and mass management in traditional architecture in Indonesia are prepared by taking into account the interaction of the outer space (in the form of open space), the transitional or intermediate space (under or terrace) and the inner space (building core) as a symbiotic and continuous entity. The potential of a tropical climate that is rich in sunlight and rainwater can be utilized in
2 J. Basic. Appl. Sci. Res. , 9(3)14-21, 2019 everyday life. Spaces are arranged in a geometric order that allows them to be ‘flowing' and 'permeable' so as to give rise to interactions - the symbiosis between spaces when used, such as the inner space and the transitional one. Recognizing space in traditional Indonesian architecture can be associated with the activities applied in it. The nature of space such as public and private spaces is not limited to the fence boundary as it is now. The residential yard or courtyard can be a public space that can be used anytime from morning to night as a place to interact and move. In traditional buildings, for example, the public can be seen in the yard or yards that mingle with one another, not limited to well-defined fences. The privacy limit can be shown in the form of a residential building. Open or semi-open spaces in the form of yards or in the form of terraces or the kolong (pit/vault) underneath can be a representation of public-togetherness ideas, while closed spaces depict a private space. Public and private spaces can be recognized through the figures displayed, namely in the form of closed-massive and open representations. The mass management of public private space can be recognized through a solid-closed- massive and void-open-transparent display. Public space can be interpreted as a shared space or space that is used as a place of daily activities both from a small scope of the family to the larger scope of the village or city. Understanding the traditional architectural space of the archipelago can be connected with the interaction of balance or integration between solid-closed-closed and void-open parts. Closed spaces have functions that are not only private but also sacred. Space in traditional architecture is interpreted as an element of sacredness and worldliness that limit one another but also synergize.

Figure 1 Symbiosis of Outer-Transition-Inner Space [12] [13] [14]
From an architectural point of view, space in the context of traditional Indonesian architecture can be understood - in its existence, emergence, and presence - in symbiotic terms between solid-massive-closed and void- transparent-open (sacred and profane, private and public) as a whole, so not as a separate unit of activity, such as interior and exterior dichotomy [15]. The integration of outer space, transition and inner nature has basically shaped the fundamental character of traditional architecture in Indonesia [1] . This is a piece of wisdom that can be developed again in modern buildings in Indonesia, including the processing of spaces that connect the exterior and interior of the building. In simple terms, it can be understood that the core elements in the architectural design of houses in Indonesia are important, as well as the processing of their outer space. Terraces/verandah and outdoor spaces in the context of buildings in Indonesia can be used throughout the year without being disturbed by winter.
3.2 Strong Elements Based on architectonic comparative studies various elements of traditional Indonesian housing architecture are identified by several strong elements, among others:
3 Citation : Rahadhian P. Herwindo, 2019, The Strong Architectonic Elements of Traditional Vernacular Architecture in Indonesia; Journal of Basic and Applied Scientific Research, 9(3)14-21.
1. Bio Mimesis and Geometric , in its sculptural or ornamental form, the building uses ornamentation such as patterns of decorative tendrils, animals, moulding in the form of a lotus, geometric square decorations, square shapes, and curves for doors.
Figure 2 Bio mimesis-Geometric, Solid Void Linear, and Cluster in Ornament and Shape [1] [14] [15] [17] [18]
Ornaments can also be painted on the skin of its inhabitants. Bio mimesis is also shown on the shape of the roof in several buildings which shows the curve elements resembling the shape of horns as well as in some building elements in texture on some parts of the roof or walls of the building. Geometric can be identified from spatial and mass and ornamentation. The building plan shows a geometric composition in the form of a straightforward and clear basic form such as a rectangle/oval/cruciform.
2. Solid Void in linear or cluster patterns. The mass shows a solid-void composition (in the form of a cluster or linear pattern) which shows the symbiosis of the unity of Inner Space, Outer Space, and Transitional Space.
3. Base Element and Top Element The building shows the bottom-base element and the top. The upper part is in the form of a body and head (roof). The building's legs can be in the form of a base that is lifted in the form of a floor of a stage-clumped or not classified (massive); or a base that is not lifted.
4. Dominant roof The roof shows the dominant proportion compared to the element of the body or its legs, so that the body appears to be part of the roof or it can also make the impression of lightness drifting using piloti (ground-level supporting columns or stilts) like pendopo - a pavilion (the dominant roof is supported by columns).The shape of the roof can be divided into two types, namely saddles and shields with various variations. In modernism architecture, the concept of the form of piloti is also known, which is heavy but makes a light impression.

5. Breathable , in the form of breathing walls arranged using materials that can drain air in the cracks both made of wooden boards, bamboo cubicles or bricks or just by employing columns so that free air flows like in a pavilion. Nowadays the idea of Breathable can be connected with the green building approach.
Figure 4 . Breathing Wall [14] [12] [19]
6. Volumetric Shape and Vertical Line element , the figure of the building shows the presence of volumetric elements for buildings that are private and sacred and elements of the vertical line for buildings that are public and profane.

7. Hierarchy- repetition in spatial and mass order and figure, the focus of interest in facade processing and mass arrangement.
8. Natural axes The mass and space are arranged by taking into account the concept of harmony with natural and environmental cosmology which is manifested in the form of an axis (this can be linear or centered), related with the orientation of the building and its footprint on the surrounding natural environment such as the sea, upstream and downstream of the river. Nowadays these idea can be related with the environmental and ecological awareness approach.
Sumba
Figure 6. Axes and Enviromental – Mountain-Sea Axis, upstream and downstream Axis [1] [22][23]
9. The structure is non-rigid, knock-down, and movable. Construction of buildings is structured with a system that is not rigid (as it can sway) and can be dismantled or moved in mutual cooperation (gotong royong) [23]. The connection system can use pegs and ties. This structural system can be associated with resilience to earthquakes.

6 J. Basic. Appl. Sci. Res. , 9(3)14-21, 2019
These elements can be considered to be transferable and transformative if they will be developed in contemporary buildings, such as voiced by postmodernism such as bio mimesis or voiced by the modernist movement [27] that is the impression of the floating pilotii mentioned above, or expressed in green building [28] or disaster mitigation such as non-rigid structures, and the like. These elements can be borrowed, reprocessed and developed into new architectural forms, so that they are relevant for both the present and future. However, in its exploration, of course, the fundamental characteristics are not ignored such as tropical architectural spaces that pay attention to the inner outer-transitional space, its figures, its ornaments, and so on. However, the traditional architecture still has limitations, for example the core house is basically only used for sleeping so that it is closed and the natural light is not optimal. In addition, on the other hand there are limitations in the structural system if further linked to high- rise modern buildings. The use of past representations makes it possible to arrive at new meanings and views or extensions of previous meanings. The meaning is always found in the negotiation process and adapted to the new situation. The point is that meaning is not inherent in something in this world, being always constructed and produced through a process of representation and being the result of marking practices [29]. the hyper-reality world is a surpassing world, created by the use of hyper-signs and hyper-signification systems in describing reality, so that the difference between reality and non-reality, the sign/reality dissolves[30]. An example in modern times is the use of the Parthenon (temple) design elements for buildings that serve governmental functions. In this case the Government is associated with the Parthenon, even though there is no realistic correlation of between the two. Parthenon elements can be hyper signed in the context of hyper-reality.
4. CONCLUSIONS
Architectural work can be seen as a symbol of dream reality as well as mythology that describes the manifestation of the deepest human desires. Symbols derived from archetype, the memory of collective ideas, and primordial images can be presented through the medium of myth-legend. Creativity in the form of design transformation is presented to produce an embodiment that can form a bridge between old ideas and new ones. This dialogic creativity is the identity and key that Indonesian society has had in the past when responding to new phenomena. The dialogue with the past shows people’s awareness of respecting their origins or identity in Indonesia. This shows sustainability in behaving and being creative in producing works dynamically. Based on the study above, there are elements that are considered significant in traditional architecture, among others, the synergy between inner space, outer space, and transitional space so that the terrace and courtyard elements become very important. The arrangement of these spaces is highly concerned about the symbiosis between outer, inner and transitional spaces such as optimizing the terraces, and semi-open foyers. Traditional architecture accentuates the proportion of dominant roofs, so that the roof element becomes become a very important element in processing building figures. The synergy of the outer-transitional-inner space and the dominant roof is a reflection of the tropical context. In addition, the spaces presented show the existence of sacred and secular nature. This constitutes a real picture depicting the religiosity of the people who live in it. The environment is an important consideration in placing space and mass, especially with regard to natural cosmology. This phenomenon shows the nature of the spirituality of the Indonesian people who greatly appreciate the synergy of nature and divinity. The concept of sacredness is also shown in the exploration of the use of symbols in the form of spatial, figurative and ornamental elements. Ornaments should not be seen as mere decorations that refer to floral and geometric shapes but also as ones carrying special meanings. At present the ornaments can be developed as part of processing the texture of the figure and façade of the building so as to convey profound meaning.

Received: September 2, 2018 Accepted: November 15, 2018 ABSTRACT
The basic requirements for good headscarves are no longer only aesthetically pleasing, but also related to the functional requirements that the head scarf should provide for the woman wearing it. Therefore, the study of the functional requirements of the head coverings of women in the Arab climate, which combines the heat in summer and cold winter is important to different dimensions in terms of selection of raw materials suitable for the manufacture of head covers and treatments to improve the head scarf to give a sense of comfort with the aesthetic appearance. The synthetic headscarf prevents the extraction of sweat and prevents air permeability, which causes many problems for women who wear it. In this study, polyester head scarf fabric will be treated with atmospheric pressure plasma to improve functional properties such as wettability, tensile strength, elongation, UV protection and protection from harmful bacteria to woman skin. The effectiveness of the treatment is assessed by using standard tests methods; first, the UPF test, second, the Antimicrobial test, finally, Infrared spectroscopy Analysis. KEYWORDS: Headscarves, Plasma surface treatment; UV protection, Infrared spectroscopy Analysis, Scanning Electron Microscopy
1. INTRODUCTION
The head cover is one of the most effective clothing supplements that can be used in many styles. It is one of the easiest ways to add a distinctive touch to clothes and give them a hint of renewal and diversity. The headdress has the ability to change the shape of old clothes and to avoid looking at the body defects when placed near aesthetic areas in the woman's body. It is also used as a function of heating in the winter season. Scarves come in different sizes, fabrics and shapes. A scarf’s fabric defines its appearance, texture, and weather-suitability. Women are among the most affected by the danger of solar radiation, especially UV radiation so women should always pay attention to fabric when they’re shopping for scarves. A lot of Headscarves made from different materials in the markets, some may be inappropriate in the way wear on the head or uncomfortable or inappropriate for use; so the study of the functional requirements of the fabrics used in the Headscarves manufacturing and attention to the requirements of the society is very important.(3) There are at least 70% of women in Egypt, Arab countries and North Africa wear headscarves for social, religious and protective reasons and sometimes for other reasons such as decorating or protection from heat and solar radiation, which increases the need to provide fabrics with high protective properties against the thermal and radiation effects of (Ultraviolet - visual - infrared) radiation, where most women suffer in these areas of damage and skin diseases such as increase the secretion of sweat and inflammation of the scalp and hair loss and lack of vitamin D and so on, causing a real problem for Arab women and psychological and moral diseases. (3) Synthetic fibers have become an integral part of the current textile industry. Polyester fiber has been most widely used for textile materials because of high mechanical strength, good stretchability, heat-setability, rapid drying, and wrinkle resistance. The main drawback of some synthetic fibers is the low surface energy that causes a weak sensitivity to moisture and dyeability. (6) It is known that polyester fiber has an inherent hydrophobic nature and thus polyester products are lacking in stain-release, anti-soil redeposition, water and moisture wicking and anti-electricity in textile end-use. The hydrophobicity can also be a disadvantage for certain applications like dyeing and finishing. Chemicals treatments are often used to improve the hydrophilic nature of the polyester headscarves surface; however, the usage of chemicals is accompanied by a decrease in fiber strength and leads to environmental pollution. Therefore, we used plasma treatment to enhance comfort properties and mechanical properties. (6)

Plasma technology is based on a simple physical principle. Matter changes its state when energy is supplied to it: solids become liquid, and liquids become gaseous. If even more energy is supplied to a gas, it is ionized and goes into the energy-rich plasma state, the fourth state of matter. (2)
Plasma treatment of textile is one of the most popular methods used for textile surface treatment; it is dry, pure and used lower energy consuming than valet ordinary treating. Plasma processing of polymers was used to get desired surface properties without interfering with material properties. Non-thermal plasma techniques were developed in the atmosphere to meet the need for the textile industry. (1) Plasma treatment causes a desirable and exactly adjustable increase in the adhesiveness and wettability of surfaces. This makes it possible to use completely new materials and environmentally-friendly, solvent-free paints and adhesives industrially. Many chemical surface treatment processes can be replaced with plasma treatment. (2)
The significance of this paper is to discussion the influence of atmospheric pressure plasma modification on women headscarves. Comfort properties, UV protection and protection from harmful bacteria to woman skin have been investigated; Methodology was undertaken using a headscarves material, with fiber content of polyester.

2. MATERIALS AND METHODS
2.1 Fabrics: Specifications of fabrics are given in table 1. Headscarves fabrics were procured from Tie shop. Thickness obtained using thickness tester according to (ASTM D1777-96-2003). Fabric weight obtained using digital sensitive scale according to (ASTM D3776-96-2003).

2.2. Experimental Methods Application of atmospheric pressure plasma treatment of polyester fabric for improvement of headscarves specific properties:
17 J. Basic. Appl. Sci. Res. , 8(7)16-25, 2018
The discharge can be produced between two electrodes one of them covered by two different dielectric material cement and glass, cell shown in Fig.2 consists of two metallic parallel square electrodes of 25x25 cm 2, 2mm gap space, separated by glass sheet through an O ring. The ground electrode stands on Acrylic sheet with inlet and out let opening for gas insertion and exhaustion. High voltage AC transformer (0-10kV) generates a 50 Hz sinusoidal voltage was used as a power source for driving discharge. (7)The live electrode is stain steel has radius 15 cm and the other electrode is covered by porous material as a dielectric with thickness 1 mm. (6) The discharge situation should be adapted to being in the glow mode through setting the used voltage and current.

Polyester fabric was exposed to atmospheric pressure glow discharge plasma (APGD) at different currents and times with different gases Oxygen, nitrogen and air. Exposing time variables were 5 min, while discharge current variables were 3, 5, 7 and 10 mA. The headscarf fabric was cut and then scoured with acetone for 10minutes to remove contaminants on the fabrics surface. After that, the headscarf fabric was rinsed with deionized water for 5minutes. Water was extracted from fabrics in a hydro extractor for 3 minutes. Lastly, the fabrics were dried in an oven at 60 ℃ for 10minutes. After scouring the fabrics, the fabrics were conditioned under the standard atmospheric pressure at 65% +/- 5% relative humidity and 21 ℃+/- 1℃ for at least 24 hours before other procedure processed. The investigation involves the application of different gases oxygen; nitrogen and air to polyester headscarf in order to improve the fabric physical properties such as wettability, tensile strength, elongation, IR- spectroscopy Analysis as well as surface morphology were also investigated. The tensile strength test and the water drop test were applied. The duration required for the drop of water to be absorbed into the fabric is pointed to as absorbency amount. In order to determine the changes in the chemical structure of polyester headscarf fiber as a result of plasma treatment, the untreated and plasma treated samples were studied by IR- spectroscopy Analysis. The scanning electron microscope photomicrograph was registered to study the changes in the surface morphology of plasma treated fabrics.
3. RESULTS AND DISCUSSION
Effect of atmospheric pressure plasma on the physical and mechanical properties of polyester headscarf fabric, Time exposure 5 min:
3.1. Infrared spectroscopy Analysis: The results are illustrated in figures (3, 4, 5 and 6). In the spectrum of the nitrogen plasma- treated fabric fig. (4), some new peaks were observed compared with untreated sample spectrum :2443.06cm characteristic of NH 2 groups, 1378.36 cm -1 characteristic of C-N aromatic amine , 1234.64cm characteristic of secondary amine C-N stretch , 1227.57 characteristic of C-N aliphatic amine and 1455.18 cm -1 characteristic of aromatic tertiary amine C-N stretch, As well some other peaks with intensity at 3368.64 cm -1 , 3357.85 cm -1, 3053.9 cm -1 characteristic of hydroxyl group H-bonded OH stretch were also observed. Fig. (5) Shows that a new absorption band with peak intensity at 1462.86 cm -1, characteristic of carboxylate groups was observed. In addition, the intensity of the hydroxyl group (-OH) peaks like 3648.27 cm -1 and 3231.15 cm -1 were outstandingly higher than that in figure (3) this increase in the absorption intensity indicates the introduction of more hydroxyl

The rate of the oxygen containing groups such as –COOH, -C-OH and C=O increased on the surface of the treated fabric. This effect may be referring to the fact that some of the C-C bonds in the polyester fabric surface could be broken by the oxygen plasma treatment. Then the carbon radicals, formed by the removal of hydrogen atoms from the polyester chain The introduction of these polar groups converts the nature of the fabric from hydrophobic to hydrophilic, as shown in figure (6), some new absorption band with peak intensity at 3298 .64 cm -1 characteristic of hydroxyl group H- bonded OH stretch was observed. Furthermore the intensity of the carboxylic acid salt group (-COOH) peaks like 1302.68 cm -1 1403.92 cm -1 and 1834.46 cm -1 were higher than that in untreated sample spectra. Also, the intensity of -1 -1 -1 the amine group (-NH 2) peaks like 2358.81 cm , 2223.82 cm 2406.63 cm were also higher than that in untreated sample spectrum, which means additional functional groups induce to the fabric surface as a result of air plasma treatment.

3.2. Wettability Wettability expressed as wetting time of untreated and treated fabrics was measured; table (2) shows the wetting times of the polyester headscarf fabric modified by different gases under different discharge current.

Table (2): Wetting time of polyester fabric modified with different Glow discharge gases:
Discharge current (MA) Untreated sample Wetting time (sec.)

3 0.72 0.82 1.02
5 0.68 0.71 0.85
7 0.61 0.65 0.79
10 0.58 0.61 0.72
It can be easily observed that the plasma treated fabrics exhibited a significant enhancement in the hydrophilicily and water absorption irrespective of gas types used under the study. The improved wettability of polyester fabric as a result of plasma treatment is in good agreement with the results of IR analysis. It could be concluded from table (2) that increase the discharge current is accompanied with decrease in the wetting time for plasma treated samples.
Wetting time (sec.)
1.2 1 0.8 Air 0.6 O2 0.4 N2 0.2 0 3 5 7 10
Fig. (7) Wetting time chart of treated polyester headscarf fabric
The improved wettability of polyester treated fabrics can be attributed to the increase in ion bombardment on the fabric surface which leads to formation of surface- free radicals, increasing the amount of active species formed on oxidation, besides increasing surface and increasing surface roughness according to the kind of gas used in glow treatment. The wettability of plasma treated polyester fabric increases in the order of Air> O2 >N2. this increase in the surface wettability is due to formation of several hydrophilic groups (e.g.,-NH,-CN,-N:N,-C=O,- COOH,-C-OH,-CHO) Beside chain scission, etching, and increasing surface roughness.
Plasma treatment resulted in improvement in hydrophilicity of polyester film which was treated along with polyester fabric in air DBD. As seen in Figure 8, an apparent decrease in water contact angle took place after 15 min plasma treatment, which suggest that a strong increase in wettability of the polyester headscarf fabric surface induced by DBD. Water contact angle was reduced from 85.7° for untreated to 29.5°, which indicate the formation of polar groups such as CO, COO, OH, etc as consequences of plasma treatment which make polyester surface more hydrophilic.

3.3. Scanning electron microscopy (SEM): SEM Measurements Figures 10, 11, 12 and 13 show the SEM micrographs of the plasma treated polyester fabric and the untreated fabric. Surface morphology changes significantly after plasma treatment. It can be showed from Figures 10 that the untreated polyester fibers look distinct and very smooth, however Figures 11, 12 and 13 show several grooves on the surface of the fibers, with the existence of some pores and voids. These results may be due to the removal of some material by etching and roughening effect caused by the bombardment of ions/ electrons in the plasma on the fabric surface, causing surface roughness.

Table3 and figure (12) Shows that the treatment of plasma caused a little reduce in the rate of the tensile strength in comparison with the untreated fabrics. Long plasma treating produced deep cracks on the samples, on the other hand, higher discharge current or longer treatment time during plasma treatment may caused lose in tensile strength properties.
3.5. Ultraviolet protection factor: it was determined using UV-VIS double beam spectrophotometer according to the standard (ASTM D6604- 2000) and AATCC test method [AATCC 183-2000]. And the results showed in table 4:

CONCLUSION
Treating polyester women head scarf with atmospheric pressure glow discharge plasma (APGD) has a significant effect on performance and functional properties.N2 treatment at low current, 3mA with 5min duration, showed a better resultant data, for polyester women head scarf. Plasma treatment caused formation of some new functional groups like, OH, COOH, CO, NH2 these additional groups were detected by Infrared analysis. The UV blocking and anti microbial properties has successfully achieved after treatment. The plasma treated fabrics exhibited a significant enhancement in the hydrophilicily and water absorption irrespective of gas types used under the study.
