71 WATER QUALITY ANALYSIS FOR THE REGION SEAWEED USING REMOTE SENSING TECHNOLOGY (REMOTE SENSING) AND GEOGRAPHIC INFORMATION SYSTEMS IN WATER ISLAND DISTRICT PURA ALOR Jahved Feriyanto Maro Institution (College of Agriculture and Fisheries) Jl. Tang’eng Kab Alor, Indonesia 85 812 e-mail: [email protected] ABSTRACT Pura Island is one of the districts in Alor Regency NTT between by two large islands and many smaller islands in the west bordering Pantar Island in the east by the Alor Island in the north bordering with Retta Island/Ternate and the south side of the island Tereweng. Community life on the island Pura dependent on dry land and fishing traditional therefore the need for land clearing new work of which is seaweed farming, it is necessary analysis land suitability for cultivation of seaweed for cover Economic Community Sector in Pulau Pura effective and efficient, The purpose of this study was to determine the carrying capacity of the waters on the island temple, knowing non-technical factors in the waters of the island temple, analyze the conformity of the waters of the technical aspects of using remote sensing data. The method primarily used in analyzing the suitability of the waters is a method of remote sensing with algorithm approach. Menujukana research results that the water quality (nitrates, phosphates, current speed and brightness) sting appropriate to serve as a regional development of seaweed cultivation in the island temple. Keywords: Islands Pura, Seaweed, Remote Sensing ABSTRACT Pura island is one of the sub-districts located in Alor NTT Regency flanked by two large islands and Several small islands in the west by Pantar island in the east, Alor Island in the north, Retta/Ternate Island and south of Tereweng Island. Community life depends on Temple Island on dry land and traditional fishery, therefore need to open a new work area such as seaweed cultivation area, need analysis of conformity of marine aquaculture cover economy with society at Island Effectiveness and Efficient. The purpose of this research is to know the carrying capacity of waters in Pura Island, to know the non-technical factors of Pura Island waters, to analyze the water suitability value from the technical aspect by using remote sensing data. The method used in analyzing water suitability is the remote sensing method with the algorithm approach. The results Showed that water quality (nitrate, phosphate, current velocity, and brightness) sting is suitable for the development of seaweed farming in Pura island.

INTRODUCTION Some of the considerations that need to be considered in determining the location is a technical Fisheries and aquaculture provide great food and condition that consists of the parameters of physics, income for the state - the state that has the coast and chemistry and biology and non-technical form of a is the source of life than 3 billion people (Amosu market share, security and human resources (Milne, and Alberto, 2012 in Gilani et al, 2015). Seaweed is 1979; Pillay, 1990). To see from the description above a potential plant the sea and is a very useful plant. background it is necessary to study the effective and Seaweed grows in shallow waters 2013, (Mohammed, efficient in cultivation area sea views from physical, Gilani et al, 2015). Seaweed can also be used as an chemical and biological waters Pura Island Alor absorbent excessive nutrient from effluent ponds as regency of East Nusa Tenggara province. revenue community fisheries and coastal economic improvement (Yousef, 2012 in Gilani et al, 2015). Seaweed cultivation is one of the solutions in II. METHODS improving the economy of coastal communities once This study is a quantitative research. A survey method revenue (PAD). In response, the Regional Government was used through observation approach (Nasution, of East Nusa Tenggara Regency Alor particular, 2012) and direct measurements and the use of data. continue to improve itself from fisheries and marine The approach used in order sector to sustain coastal economic communities. remote sensing spatial to present the modeling the spatial aspects of a Settling himself in question is the government’s phenomenon that occurs in nature (Budiyanto, 2005). attempt to analyze coastal areas which are potentially in the development of seaweed farming a small island in East Nusa Tenggara is located in Alor district is 1. Data analysis Pura Island. Analysis Data in this study, consisting of a stage of In Sub island Pura there are 5 villages (Pura making the contour and spatial modeling, which South, Maru, Pura East, Pura West and Pura North is based on a geo-statistical model, which refers to and one village (temple) with the lives of people Hartoko (2011). The following stages are aquatic still very bergatung on pengkapan fish and dry land suitability analysis by making suitability matrix. The management (farming) to prop up the economy, a lot next step forming zones at the location with the overlay of obstacles faced by the people of the island Pura (Hartoko 2011 in Kangkan, 2006). manage dryland attributable to the lack of fresh water Development of this model is based on data (fresh water), it is becoming kedala heavily in dryland transfer Geodetic/position (Degree, Minute, management so that the island of Pura spend their Second/DMS) to obtain a single value, the formula: time with pengkapan fish and manufacture of gin (a The numerical value (Lat; Long) = Degree + {Minute + local drink berallkohol tebuat of fruit palm) due largely (second/60}/60. to 85% dry land temple overgrown Lontar. this impact Software Arc Gis 10.2 used as a data processing is very harmful to the surrounding environment. facility. To obtain data regarding the supporting Therefore, it is necessary to attempt to clear land a factors used interview techniques where the people new job in supporting the local community economy are fishermen who really know and recognize the by way of determination of the area of marine circumstances and conditions of coastal waters aquaculture (mariculture) in Pura Island. concerning Pura Island. Based on the history of farming in various Preparation of water suitability matrix is the basis world, it can be concluded that the selection of the of spatial analysis through the scoring and weighting right location is an important factor in determining factors according to the instructions (Bakosurtanal, the feasibility of cultivation (Milne, 1979). Despite 1996 in Kangkan, 2006). the efforts and technology, some units are not suitable to be converted into a profitable or even had to be abandoned after spending large sums. Therefore, the 2.
