KONSENTRASI SENYAWA DIMETILSULFIDA (DMS) DI PANTAI UTARA JAWA BARAT DAN KEMUNGKINAN DAMPAKNYA PADA PRODUKSI UDANG

Abstract


Shrimp culture has became one of the most important Indonesian export
commodity since 1985 up to the beginning of 1990`s. Due to the
increasing intensification, the pressure on the shrimp ponds environment
has became a serious problem. The problem was indicated by the
decrease in shrimp production since 1992. Dimethylsulfide (DMS) is
known as a major contributor to total sulfur emission from land and coastal
marine and also known to inhibit nitrification. In this respect, we are
studying the influence of DMS on nitrification process in saline water.
This paper describes the DMS concentration observed in several places in
the Western Coast of North Java. The minimum and maximum concentrations observed were 790.32 ηM and 6483.87 ηM respectively. These figures are higher than concentration detected in any other coastal area where shrimp productions are concerned. We speculate that DMS has given some contributions in the depletion of shrimp production.
