POLA DINAMIS PENURUNAN HASIL TANGKAPAN UDANG AKIBAT PENGENDAPAN DAN LIMBAH INDUSTRI DI KAWASAN SEGARA ANAKAN (Dynamic Pattern of Degradation of Shrimps Catch as an Effect of Sedimentation and Industrial Waste in Segara Anakan)
Abstract
Abstract
Segara Anakan, Cilacap Regency is an important marine fisheries producer in Central Java
Province, especially for shrimps. The objective of this study were to analyze the production and
fishing ground of shrimps, to analyze dynamic patterns of shrimps cat ch affected by sedimentation
and industrial waste in Segara Anakan, and to develop intervention option to the degradation of
shrimp catch as well. Some methods were used in this study such as descriptive method,
geographic information system, and dynamic model approach included the test of model structural
stability and performance. In 2002–2013, the highest production of shrimps in the Segara Anakan
was in 2006 (2263.0 ton) and the lowest was in 2010 (884.7 ton). Fishing ground of shrimp in the
Segara Anakan already had high total suspended solid, and also low contaminated oil and lead
(Pb). Results of dynamic model analysis showed that shrimp catch degraded exponentially along
with the increasing of sediment accumulation and industrial waste. Shrimps production in 2013 was
1147.8 tons, and might decrease 43.04 % to be 653.8 tons over 75 years later without
intervention. If the model was intervenced by fishing open -close system and limited acces fishing
ground, hence shrimps catch showing stable around 902.2–929.1 ton every year. While if the
intervention was conducted by the stopping of industrial waste to Segara Anakan, hence shrimps
catch only decrease 13.00 % to be 998.6 tons over 75 years later.
Keywords: dynamic model, fishing ground, industrial waste, shrimp catch

ABSTRAK
Segara Anakan, Kabupaten Cilacap merupakan basis produksi perikanan laut yang penting
di Provinsi Jawa Tengah terutama jenis udang. Penelitian ini bertujuan menganalisis kondisi
produksi dan daerah penangkapan udang, menganalisis pola dinamis penurunan hasil tangkapan
udang akibat pengaruh pengendapan dan pembuangan limbah industri di kawasan Segara
Anakan, serta mengembangkan alternatif intervensi secara modelling terhadap penurunan
tersebut. Metode yang digunakan terdiri dari metode deskriptif, sistem informasi geografi,
pendekatan model dinamis, serta uji kestabilan struktur dan kinerja model. Pada periode tahun
2002 – 2013, produksi tertinggi udang terjadi pada tahun 2006 (2263,0 ton) dan terendah terjadi
pada tahun 2010 (884,7 ton). Daerah penangkapan udang di kawasan Segara Anakan mempunyai
total padatan tersuspensi dan kekeruhan yang tinggi, serta tercemar ring an oleh minyak dan logam timbal. Analisis model dinamis menunjukkan bahwa hasil tangkapan udang cenderung menurun
secara eksponensial seiring meningkatnya akumulasi endapan dan cemaran limbah industri dari
waktu ke waktu. Hasil tangkapan udang yang saat ini (tahun 2013) mencapai 1147,8 ton, bisa
menurun 43,04 % menjadi 653,8 ton setelah 75 tahun kemudian. Bila model tersebut diintervensi
dalam bentuk penerapan sistem open-close dan pembatasan daerah penangkapan yang bisa
diakses, maka hasil tangkapan udang cenderung stabil pada kisaran angka 902,2 – 929,1 ton
setiap tahunnya. Akan tetapi bila intervensi dilakukan dalam bentuk penghentian pembuangan
limbah industri ke kawasan Segara Anakan dan sekitarnya, maka hasil tangkapan udang hanya
turun 13,00 % (menjadi 998,6 ton) setelah 75 tahun kemudian.
