PENENTUAN LOKASI BUDI DAYA RUMPUT LAUT (Euchema spp.) BERDASARKAN PARAMETER LINGKUNGAN DI PERAIRAN KECAMATAN MORO, PROVINSI KEPULAUAN RIAU
Abstract
Penelitian ini bertujuan untuk melakukan identifikasi kelayakan perairan untuk budi daya rumput laut dengan menggunakan metode long line berdasarkan parameter lingkungan di perairan Kecamatan Moro Provinsi Kepulauan Riau. Sebanyak 87 stasiun telah dikumpulkan selama survai lapangan pada bulan Agustus dan Oktober 2004. Data parameter lingkungan dan data penginderaan jauh selanjutnya dianalisis dengan menggunakan sistem informasi geografis dan multi kriteria analisis. Dari total potensial lokasi penelitian seluas 417 km2 (jarak 1 km dari garis pantai), kategori sangat layak di temukan di perairan sekitar Pulau Sugie dan Pulau Combol seluas 110 km2. Hasil verifikasi dari klasifikasi tingkat kelayakan menunjukkan bahwa sekitar 44% dari budi daya yang ada menempati kategori sangat layak. Terdapat sekitar 6% yang menempati perairan dengan kategori tidak layak.
This study was conducted to identify suitability site for seaweed culture using long line method based on environmental parameters in adjacent water of Moro Sub District, Riau Island Province. Field observation was primary data sources used in this study that was conducted on August and October 2000. Total of 87 sampling stations were collected during the field survey. Environmental data together with remote sensing data were analyzed using geographic information system and multi criteria analysis. The final result showed that from the total potential site of about 417 km2 (1 km buffer from coastline), area around Sugie Island and Combol Island (about 110 km2) were classified as highly suitable. The result has been verified with the existing seaweed aquaculture. About 44% of existing seaweed culture matched with highly suitable site and about 6% was located in unsuitable site.
