MARINE WATER QUALITY ASSESSMENT USING BIOLOGICAL ORGANISMS AS INDICATOR AROUND FISH LANDING BASE IN KARANGANYAR, REMBANG, INDONESIA

SLAMET ISWORO AND POERNA SRI OETARI

Abstract

The development of fish landing bases in Karanganyar is a national fishery program in Indonesia, but this development project certainly has consequences because it can cause changes in ecosystems in the sea waters around the project site. This study aims to determine the initial conditions as the basis and general description of marine waters and the impact that will occur due to the construction of Karanganyar fish landing bases. Analytical method of sea water analysis used is an atomic absorption spectrometer, while for biological parameters is Shannon diversity index. Based on the results of the seawater quality analysis, some parameters have exceeded the standard of total solid suspended was 106 ppm - 134 ppm, ammonia ranges 210 ppm - 775 ppm, phenol ranges 0.02 ppm - 0.02 ppm, oil fat ranges 65 ppm - 251 ppm, cadmium ranges 0, 01 ppm - 0, 04 ppm, lead ranges 0, 08 ppm - 0, 21 ppm and total coliform ranges 7 x 103 - 20 x 103. The saprobic value index was 1 and the tropical saprobic index ranges from 0.16 to 0.34, indicating the - mesosaprobic status. The nekton diversity index is 1.74, and the necton uniformity index 0.83 shows the stable category. The results of sea water quality analysis showed that some parameters exceeded the allowable limits, while based on the saprobity index showed mild to moderate polluted waters.
