Pollution Status and Water Carrying Capacity for Intensive Vaname Shrimp Cultivation on the Cilacap Coast, Central Java

Abstract The Cilacap coast of Central Java has a large potential for sandland to be used as shrimp cultivation area. The development of shrimp cultivation in that region certainly has an environmental impact and sustainability of the area. Waters quality and carrying capacity are both important ecological aspects in supporting the sustainability of vaname shrimp cultivation. This study was conducted from May to July 2022, and aims to identify water quality status and analyze the carrying capacity of waters on the coast of Cilacap (namely Tegalkamulyan, Menganti, and Slarang). Analysis of water quality status was carried out using the Calculation of Pollution Index (PI), while the carrying capacity analysis was carried out using the water volume capability approach to accommodate waste. The results of the pollution index calculation stated that the location of Tegalkamulyan had an PI value of 5.0 (minor polluted), Menganti had an PI 4.1 (minor polluted), and Slarang with a value of PI 5.1 (moderately polluted). The calculation of the carrying capacity shows that the activity of vaname shrimp cultivation has exceeded its carrying capacity, where the productivity value of Vaname shrimp in 2022 reached 901.258 tons/year
