Information regarding fishing grounds was needed to assist fishermen in their activities. about the sea surface chlorophyll-a concentration (SSCC) and temperature (SST) could be used as a reference identify potential zones (PFZ). The purpose of this study SST SSCC data using MODIS (Moderate Resolution Imaging Spectroradiometer) satellite imagery for determining PFZ analyzing distribution pattern seasonally. determination point carried out by overlaying based on results image processing....
Berbak Sembilang National Park of South Sumatra Region (BSNP Sumatera) is the largest mangrove ecosystem in western part Indonesia. Monitoring coverage BSNP Sumatera carried out using Landsat-8 imagery data based on NDVI values (Normalized Difference Vegetation Index) integrated with LAI (Leaf Area data. The research purpose was to analyze and mapping density vegetation canopy integration remote sensing LAI. This conducted field survey measurement validate map. determination correlation...
Fitoplankton di laut mempunyai peranan penting sebagai pembentuk dasar dari rantai makanan (food-chain) dan bertanggung jawab dalam produksi primer (primary production). Kelimpahan jumlah jenis fitoplankton secara tidak langsung akan mempengaruhi tingkat kesuburan suatu perairan. Penelitian ini bertujuan untuk mengetahui keberadaan ditinjau kelimpahan, indeks keragaman, keseragaman, dominansi estuaria Banyuasin, Sumatera Selatan. dilakukan pada bulan September 2017 sebelas stasiun. Contoh...
Komunitas gastropoda merupakan salah satu komponen penting dalam rantai makanan di padang lamun. Penelitian ini bertujuan untuk mengetahui komposisi jenis, kerapatan lamun, kepadatan gastropoda, indeks komunitas dan hubungan antara lamun dengan Perairan Pulau Tangkil. dilaksanakan pada bulan Mei – Juli 2018, menggunakan metode transek linier kuadrat 1x1 m. Pengambilan data dilakukan 4 stasiun, dimana setiap stasiun dibagi menjadi 3 pengukuran parameter fisika kimia perairan pengulangan...
