Abstract

Pemetaan lahan yang potensial untuk budidaya perikanan dilakukan melalui pemetaan topografi dan tutupan lahan dari citra satelit serta survei lapang di perairan pantai Timur Belitung. Peta Topografi estimasi dari citra satelit mempunyai pola yang sama dengan hasil pengukuran terestris dimana ketinggian lahan semakin meningkat mulai dari garis pantai menuju daratan. Data hasil pengukuran topografi secara terestris lebih tinggi dari data topografi estimasi dari data satelit. Tipe pasut di perairan pantai Belitung timur adalah tipe tunggal. Data pasut ini digunakan menjadi acuan untuk pengukuran topografi secara terestris. Peta tutupan lahan hasil intrepretasi dari citra satelit diklasifikasikan menjadi kelas: hutan primer, hutan sekunder, belukar, rawa/air, lahan terbuka, permukiman dan galian tambang. Berdasarkan peta topografi, peta tutupan lahan dan data pasang surut maka lahan di wilayah kajian pesisir pantai Timur Belitung potensial dikembangkan untuk budidaya perikanan seluas 9.000 ha.

ABSTRACT

Mapping potential land for aquaculture was done through topography, and land cover mapping derived satellite imagery and field survey in the east coast of Belitung. Topographic data derived satellite, and terrestrial measurement shows that topographic patterns increase as we move from the coastal line to inland. Topographic data from the terrestrial measurement was higher than satellite estimations. The type of tide in the east coast Belitung’s is the diurnal type. Within this research, tidal data was used as a reference terrestrial topographic measurement. Land coverage maps from satellite images were classified into primary and secondary forests, grove forests, marsh/water lands, open land, inhabited land, and mining areas. According to topographic, land cover map, and tide pattern it can be confirmed that the eastern coastal area of Belitung has the potential to be developed into an aquaculture fishery area of 9,000 ha.
