(Pb) Pollution in the River Estuaries of Jakarta Bay
The Sustainable City IX, Vol. 2 1555 Analysis of lead (Pb) pollution in the river estuaries of Jakarta Bay M. Rumanta Universitas Terbuka, Indonesia Abstract The purpose of this study is to obtain information about the level of Pb in the sediment of the estuaries surrounding Jakarta Bay and to compare them. Samples were taken from 9 estuaries by using a grab sampler at three different location points – the left, right and the middle sides of the river. Then, samples were collected in one bottle sample and received drops of concentrated HNO3. The taking of samples was repeated three times. In addition, an in situ measurement of pH and temperature of samples was taken as proponent data. The Pb concentration of the river sediment was measured using an AAS flame in the laboratory of Balai Penelitian Tanah Bogor. Data was analyzed statistically (one way ANOVA and t-test student) by using SPSS-11.5 software. The results show that Pb concentration in the sediment of the estuaries surrounding Jakarta was quite high (20–336 µg/g). The sediment of Ciliwung River in the rainy season was the highest (336 µg/g). Pb concentration of sediment in the dry season was higher than that in the rainy season, except in Ciliwung River. It was concluded that all rivers flowing into Jakarta Bay make a significant contribution to the Pb pollution in Jakarta Bay, and the one with the largest contribution was Ciliwung River. Keywords: Pb, sediment, estuaries, dry season, rainy season, AAS flame. 1 Introduction Jakarta Bay (89 km of length) is formed as a result of the extension of Karawang Cape in the eastern region and Kait Cape in the western region into the Java Sea (Rositasari [1]). -
Demand in Indonesian Domestic Air Travel Market After Deregulation
Advances in Engineering Research (AER), volume 147 Conference on Global Research on Sustainable Transport (GROST 2017) DEMAND IN INDONESIAN DOMESTIC AIR TRAVEL MARKET AFTER DEREGULATION Basri Fahriza1,2, Frank Willey1 1. RMIT University, 2. STMT Trisakti. corresponding author: [email protected] Abstract: This research is exploring the change of domestic air travel market demand in Indonesia prior and post deregulation. Changes on policies in Indonesian aviation were contributed to the present day market. This historical overview will examine the ‘oligopoly policy’ with only five airlines and the deregulation process that began in 1999. The research then analyses the demand for domestic air travel. Exponential Moving Average Growth were using to analysing data to forecasting the number of passenger from year 2007 to 2015 in yearly basis. Demand is then analysed on three separate airline routes in Indonesia they are Jakarta-Medan, Jakarta-Surabaya, and Jakarta-Pontianak. Keywords: Demand, Domestic Air Travel, Deregulation, Passeneger, Indonesia. Introduction Deregulation in Indonesia start when governments remove restrictions on airlines business Indonesia to encourage the efficient, competitive and consumer oriented marketplace in Indonesian airline industry (Williams, 1993). Secretary General of the Ministry of Communications Anwar Suprijadi said the decision to deregulate was taken in a bid to promote fair competition in domestic airline services, (“Govt insists on licensing more airlines,” 1999). And resulting numbers of new Indonesian airlines emerged predominantly mostly in the cut-fare sector including Lion Air; Indonesia’s Air Asia, former Adam Air, former Batavia Air and Sriwijaya Air, radically changing the nature of the airline business in Indonesia with present of low cost carrier. -
Vol-5, Issue 2
International Journal of Management Sciences and Business Research, Feb-2016 ISSN (2226-8235) Vol-5, Issue 2 Analysis on the Factors Causing Airlines Bankruptcy: Cases in Indonesia Author’s Details: (1)Suharto Abdul Majid-Faculty of Economic and Business, Padjadjaran University, Bandung, Indonesia (2) Sucherly - Faculty of Economic and Business, Padjadjaran University, Bandung, Indonesia (3) Umi Kaltum- Faculty of Economic and Business, Padjadjaran University, Bandung, Indonesia Abstract the high growth of national aviation services after the aviation deregulation in 2000 has given a positive impact on the increase of national economic activities, especially in tour and trade. In the same time, however, it negatively impacts the aviation business itself, making many airline companies stop their operation and then go to bankruptcy. The aim of this research is to analyze the factors causing bankruptcy to some national airline companies in Indonesia after the aviation deregulation in the periods of 2001-2010 and 2011-2015. It is an exploratory research with a qualitative descriptive approach emphasizing on evaluating the factors causing bankruptcy to a number of domestic airlines in Indonesia. The method of data collection is an interview with the format of focus group discussion (FGD), while the data analysis uses factor analysis method. The results of this research show that there are two main factors that cause bankruptcy to a number of domestic airlines in Indonesia. They are both internal and external factors of the companies. Key words: Airline companies bankruptcy, internal factors, and external factors. INTRODUCTION Since the implementation of the national aviation deregulation policy in 2000, the growth of aviation business in Indonesia increases rapidly. -
Water Quality of Angke River: Microbiological Point of View
82 Tjampakasari and Wahid Med J Indones Water quality of Angke River: Microbiological point of view Conny Riana Tjampakasari, Mardiastuti H Wahid Abstrak Penelitian ini merupakan bagian dari penelitian multidisiplin di Kali Angke. Tujuan dilakukannya penelitian ini adalah untuk mengetahui kualitas air sungai ditinjau dari aspek mikrobiologik di beberapa lokasi sepanjang Kali Angke. Lokasi yang diteliti meliputi: Duri Kosambi, Pesing Poglar, Teluk Gong, Pantai Indah Kapuk dan Muara (4 titik). Pemeriksaan dilakukan berdasarkan petunjuk standar Departemen Kesehatan, Republik Indonesia dan hasilnya disimpulkan sesuai Peraturan Pemerintah Republik Indonesia. Parameter yang digunakan dalam uji mikrobiologi adalah most probable number (MPN) dari total dan fecal coliform, yang dilakukan dalam 2 langkah: uji presumtif dan uji konfirmasi. Uji lengkap dilakukan untuk mengkonfirmasi adanya E.coli dan bakteri lain dalam air. Hasil yang didapat menunjukkan bahwa mutu air Kali Angke kurang baik dan tidak dianjurkan sebagai air minum. Berdasarkan parameter mikrobiologik, kualitas air sungai ini dikategorikan sebagai kelas 2 yang artinya hanya dapat digunakan untuk rekreasi air, pembudidayaan ikan air tawar, peternakan, mengairi pertanaman dan atau peruntukkan lain yang memper syaratkan mutu air yang sama dengan kegunaan tersebut. Most probable number dari total coliform di daerah Pantai Indah Kapuk dan bagian luar daerah Muara lebih rendah dari daerah lainnya. Masyarakat yang tinggal di Pantai Indah Kapuk memiliki tingkat ekonomi yang lebih tinggi, dengan demikian dapat diasumsikan bahwa masyarakat ini memiliki tingkat pendidikan yang lebih tinggi dan memiliki kesadaran tentang kebersihan lingkungan yang lebih baik. Selanjutnya, air di daerah paling luar dari Muara memiliki kadar garam yang tinggi sehingga dapat membunuh bakteri-bakteri patogen. Akhir kata, kualitas air di sepanjang Kali Angke adalah air kelas dua yang tidak layak minum kecuali di daerah Pantai Indah Kapuk dan Muara yang layak minum sesudah dididihkan. -
Metal Speciation in Sediment from Muara Angke, Jakarta Bay Using of BCR Sequential Extraction Procedure
ILMU KELAUTAN: Indonesian Journal of Marine Sciences March 2019 Vol 24(1):23-30 ISSN 0853-7291 Metal Speciation in Sediment from Muara Angke, Jakarta Bay Using of BCR Sequential Extraction Procedure Lestari* and Fitri Budiyanto Research Centre for Oceanography, Indonesia Institute of Science Jl. Pasir Putih I Ancol Timur Jakarta Utara 14430, Indonesia Email: [email protected] Abstract The assessment of the biological availability of metals is rarely used only by knowing the total concentration of the metal. Therefore, six sediment samples from Muara Angke, Teluk Jakarta were assessed the chemical speciation of heavy metals. This study aims to determine metal speciation using the BCR sequential extraction procedure and to determine metal speciation to evaluate bioavailability in the sediments of Muara Angke, Jakarta Bay. In sediment from Muara Angke, the ability to move sequence of heavy metals studied was Pb>Zn>Cu>Ni. The mostly accumulated in the non-residual fraction of the total concentrations are Cu, Ni, Pb and Zn which indicated that the mobility and anthropogenic inputs of these metals in Muara Angke were quite high. The Risk Assessment Code (RAC) reveal that Zn and Ni at almost station exist in exchangeable and a fraction of carbonate-bound and therefore high-risk category. Most of the Cu at most of the station is in the oxidizable fraction, except a small portion found at all station is in the exchangeable fraction and fraction of carbonate-bound thus posing a low risk for the waters environment. The patterns of Pb speciation show no to low risk to the waters environment. -
Numerical Simulation of Cohesive Sediment Transport in Jakarta Bay
International Journal of Remote Sensing and Earth Sciences Vol. 6: 65-76 (2009) © IReSES NUMERICAL SIMULATION OF COHESIVE SEDIMENT TRANSPORT IN JAKARTA BAY I. M. Radjawane1 And F. Riandini2 Abstract. The 3D-numerical model has been applied to simulate the current circulation and cohesive sediment transport in the Jakarta Bay, Indonesia. Sediment load comes from 3 river mouths i.e. Angke River, Karang River, and Ancol River. The model was simulated to analyze the effect of tidal current and river discharge. A constant westerly and easterly wind was used as input of the model to see the influence of monsoonal season. The numerical results showed that the tidal current flows from east to western part of the bay during ebb tide and vice versa during flood tide. The surface current circulation was dominantly influenced by the tidal current compared with the wind and river discharge effects. High turbidity level was found near the river mouths with the range of 50 to 100 mg/l. This high sediment concentration was caused by the effect of sediment load from the river upstream. In the offshore area of the bay the sediment concentration decreases up to 10 mg/l. The movement of sediments followed the current circulations. During the flood tide, the sediment concentration from the mouth of Angke River moved to the western part of the bay. Model simulated for increasing the river discharge into two times showed that the sediment distributed to the offshore direction two times longer compare with the normal debit. The transport of sediment from the Angke and Karang Rivers to the offshore area reached > 6 km, while it just reached + 2,5 km from the Ancol River . -

LIFEWAYS 37 International Journal of Society, Development and Environment in the Developing World Volume 3, Issue 1, April 2019 (37-54) Development Characteristics of a Coastal Slum Area in Indonesia: A Case Study of Fishermen Settlements in Muara Angke, North Jakarta RATNAWATI YUNI SURYANDARI1, LAILI FUJI WIDYAWATI1 1Department Urban and Regional Planning, Esa Unggul University, Jakarta, Indonesia Correspondence: Ratnawati Yuni Suryandari (email: [email protected]) Abstract As a fast developing and urbanizing country, the problem of slums those unplanned and unorganized settlements - does not only hit big cities, but almost every region in Indonesia. One such example can be found in the coastal areas of– Muara Angke, a fishing settlement area located in North Jakarta. This study identifies and analyses the characteristics of slum areas in Muara Angke based on seven physical criteria, namely, buildings, roads, drinking water, drainage, waste, garbage and fire protection. Primary data were obtained from a questionnaire survey of 70 local respondents supplemented by field observations. Secondary data were gathered from published and unpublished documents. Results of the study revealed that improvements of living conditions in the fishing slum village of Muara Angke were at moderate-to-very high levels. While buildings in the Muara Angke slums were of irregular quality, the quality of the fire protection service in the slums was moderately low. By contrast, the scores for building density was high as was the supply of drinking water and the provision of local drainage. In terms of environmental quality in the slums, road conditions, waste water management and solid waste management received very high scores. -
