STUDI PERBANDINGAN KONSENTRASI KLOROFIL-a PADA TAMBAK BANDENG TRADISIONAL DAN TAMBAK BANDENG INTENSIF MENGGUNAKAN CITRA LANDSAT 8

Abstract

ABSTRACT Based on the results of the socio-economic survey by the Directorate General of Strengthening Competitiveness of Marine and Fishery Products, Ministry of Marine Affairs and Fisheries, the Republic of Indonesia in 2014 it shows that fish consumption by Indonesian people is still low. Therefore, the government aims to increase fish production in order to increase fish consumption by the community. Based on data from the Office of Marine and Fisheries of Central Java Province in 2010, aquaculture ponds is the most potential cultivation. The selection of the most effective method of aquaculture between traditional and intensive methods is very necessary in order to optimize the fish production. One indicator of the effectiveness between the two methods can be seen from the content of phytoplankton. Phytoplankton contains chlorophyll-a in its body and is a natural food of fish. Remote sensing technology can be used to determine the concentration of chlorophyll-a by using the Wouthuyzen, Wibowo, Pentury, Much Jisin Arief and Lestari Laksmi algorithms. The results showed a relatively better Pentury algorithm used to determine the concentration of chlorophyll-a in shallow waters (ponds). The lowest chlorophyll-a concentration in traditional ponds is 0,47068 mg/m3, the highest concentration 1,95017 mg/m3 and the average concentration is 1,12893 mg/m3, while in intensive ponds the lowest concentration is 0,36713 mg/m3, the highest concentration 3,17063 mg/m3 and the average concentration is 1,53556 mg/m3 .
