Analisis Hubungan Produktivitas Ikan Lemuru Dengan Suhu Permukaan Laut Dan Klorofil-a Menggunakan Citra Satelit Aqua Modis (Studi Kasus : Selat Bali)

Abstract

Bali Strait is water territory located between Java Island and Bali Island where Sardinella is the the main commodity. Because of its location which influenced by Java Sea and Indian Ocean, it causes this area to have lots of nutrient for fish food source.As the technology advances, so to determine the Bali Strait in this using remote sensing method to process the captured image for information Modis Aqua Sea Surface Temperature and Chlorophyll-a as a parameter Sardinella abundance of fish in the Bali Strait sotfware processed using ENVI, ER Mapper , and ArcGIS 10. The aim of this research is to know the correlation between the catch result of Sardinella and the Sea Level Surface temperature in Bali Strait from 2011 to 2013.The result of this research shows that during those three years the catch result of Sardinella has been increased fluctuating with the peak average is occurred during the west monsoon (November-April) In 2011 the highest production of Sardinella was occurred in November as 752 470 kg, in 2013 the highest production occurred in October as up to 2,120,447 kg. From the single regression analysis between Sardinella catching with Seal level Surface Temperature and Sardinella catching with A-chlorophyll obtained regression mark in west monsoon is greater than east monsoon means Sardinella is bigger in the west monsoon in Bali Strait. Whereas, the double regression mark between the Sardinella catching result with of sea surface level temperature and A-chlorophyll shows that there is relationship between the amount of Sardinella catching with the sea surface level temperature and A-chlorophyll
