PEMETAAN KELAYAKAN LAHAN BUDI DAYA IKAN LAUT DI KECATAMAN MORO, KEPULAUAN RIAU: DENGAN PENDEKATAN SISTEM INFORMASI GEOGRAFIS
Abstract
Sistem informasi geografis telah digunakan untuk menganalisis kelayakan lahan budi daya ikan laut di perairan Kecamatan Moro, Kepulauan Riau. Pengumpulan data lapangan telah dilakukan pada bulan Agustus dan Oktober 2004 dengan menggunakan metode acak sederhana. Parameter penting penentuan kelayakan lahan budi daya ikan laut sesuai dengan data yang dikumpulkan digolongkan atas dua kriteria yaitu faktor lingkungan (meliputi: kedalaman, kecerahan, kecepatan arus, dan tinggi gelombang) dan faktor kualitas perairan (meliputi: suhu, salinitas, kandungan oksigen, dan pH). Pembobotan faktor dan parameter kelayakan lahan dilakukan dengan menggunakan teknik multi kriteria analisis. Hasil analisis spasial dengan menggabungkan faktor lingkungan dan kualitas air, secara umum menunjukkan bahwa perairan Kecamatan Moro tergolong layak, cukup layak, atau sangat layak, dan tidak ditemukan daerah yang tidak layak untuk budi daya ikan laut.
This study used geographic information system to analysis site suitability of marine fish culture in adjacent water of Moro Sub District, Riau Archipelago. Simple random sampling was used for collecting data on August and October 2004. Important parameters for marine fish culture from field measurement were categorized into two criteria, namely environmental factor (include: bathymetry, transparency, water current, and wave height) and water quality factor (include: temperature, salinity, dissolve oxygen, and pH). Multi criteria analysis (MCA) technique was used to weight of factors and parameters. Based on overlay of environmental factors and water quality factors using spatial analysis showed that most of areas of Moro sub district (Riau Archipelago) were identified as being suitable, moderately suitable or highly suitable, and none was identified as totally unsuitable for marine fish culture.
