Environmental Quality of Shrimp Ponds in the Coastal Region of Brebes Regency

Abstract

The largest utilization of coastal areas in Brebes Regency is the shrimp farming ponds. Shrimp volume statistics until 2016 showed that shrimp production in Brebes tends to decrease. The decrease in shrimp production can be caused by disruption in the environmental quality from the surrounding activities. This study aims to analyze the causes of declining production based on the quality of the physical environment of shrimp ponds. The variables used are water quality values (Ph, Tds / Ec, and salino), vegetation values of ponds, and waste disposal values around ponds <1000m, 1000-2000m,> 2000m. The data used is a Quick Bird image as of 2015 to determine the area of shrimp ponds and results of field survey in February 2018 for water quality sampling and observation. The analytical method that is used is scoring and weighting. The grades of pond environment quality that are produced are Poor; Good; and Well. The results show that the subdistricts of Brebes and Wanasari have well environmental quality; Tanjung has good environmental quality; and environmental value of Bulakamba and Losari subdistricts have poor environmental quality. Environmental quality is strongly influenced by industrial activities, onion farming activities, and settlements. This environmental quality study can be utilized for the management of sustainable shrimp farming.
