Abstract

ABSTRACT Site selection for seaweed culture faces some problems that require more cost, time, and energy. Technology such as remote sensing and geographic information systems (GIS) were regarded as good solutions for site selection to increase seaweed culture. The aim of this study was to analyze suitable location for seaweed culture at Gerupuk Bay, West Nusa Tenggara. The site selection used Landsat 8 satellite with sea surface temperature (SST), total suspended matter (TSM), and protected location as the parameters. Each parameters were processed using Er Mapper 7.0 software and then Arcview GIS 3.2 software to create the thematic GIS map. Site selection for seaweed culture could be determined by maps overlay technique. The results of this study showed that the most suitable site for seaweed culture at Gerupuk Bay was 342.44 ha (25.22%), moderate suitable site was 190.78 ha (14.05%), and unsuitable site was 669.32 ha (49.3%). Keywords: GIS, remote sensing, location suitability, seaweed culture  ABSTRAK Penentuan lokasi budidaya rumput laut sering mengalami kendala yang membutuhkan banyak biaya, waktu, dan tenaga. Teknologi berupa penginderaan jauh (inderaja) dan sistem informasi geografis (SIG) menjadi solusi yang baik dalam penentuan lokasi yang sesuai untuk pengembangan budidaya rumput laut. Penelitian ini bertujuan untuk menganalisis kesesuaian lokasi budidaya rumput laut perairan Teluk Gerupuk, Nusa Tenggara Barat. Penentuan kesesuaian lokasi budidaya rumput laut menggunakan citra satelit Landsat 8 dengan parameter suhu permukaan laut (SPL), muatan padatan tersuspensi (MPT), dan keterlindungan. Parameter tersebut diolah menggunakan perangkat lunak Er Mapper 7.0 kemudian dilakukan pengolahan SIG menggunakan perangkat lunak Arcview GIS 3.2 sehingga dihasilkan peta tematik. Peta tematik tersebut ditumpang susun sehingga dihasilkan peta kesesuaian lokasi budidaya rumput laut. Hasil penelitian ini menunjukkan bahwa lokasi yang sesuai untuk budidaya rumput laut di Teluk Gerupuk adalah 342,44 ha (25,22%), luas lokasi cukup sesuai adalah 190,78 ha (14,05%), dan luas lokasi tidak sesuai adalah 669,32 ha (49,3%). Kata kunci: SIG, penginderaan jauh, kecocokan lokasi, budidaya rumput laut

Abstract

Locating a suitable site is the key to success in cultivating seaweed, as it is becomes one of the coastal and marine prospects for improving the national economy. Numerous factors such as water movement, substratum, depth, salinity, light intensity, surface water temperature, influence the growth of this aquatic plant, and should be considered while choosing a farming area. One of key parameters on studying sea water conditions is surface temperature distribution, as changes on temperature effecting physical, chemical, and biological condition of the sea water. Surface waters temperature is affected by radiation, and sun position, geographic, seasons, overcast, interaction process between air and waters, evaporation level, and wind blowing. It's rarely easy job to measure surface waters temperature, because often, researcher has to deal with strong winds and high waves. The objectives of this research is to do surface waters temperature mapping of Grupuk Bay – West Nusa Tenggara, using thermal infrared channel of Landsat8 data, which is supported by field observation data. Surface temperature measurement is conducted through field survey in conjunction with Landsat 8 orbit. Surface temperature calculation is carried out by using certain method issued by United States Geological Survey (USGS, 2013). Calculation result on Grupuk Bay's water surface temperature shows that it ranges from 28.00 to 30.00oC, while field survey result shows that it ranges from 28.27 to 29.69oC. This research shows that sea surface temperature measurement result based on Landsat8 data has nearly identical range with field survey result.
