“…The decreasing trend of mud crab production and mangrove area in this model will threaten the sustainability of mud crab fisheries if neglected. Previous studies on the decline of mud crab habitat have been reported in which there was a decline in mangrove area in Segara Anakan area of around 129.63 ha per year in 2006-2014 [23] where the mangrove area reached 21,500 ha in the past [34], and there were 6,126.3 ha remaining in 2016 [17]. The decline in mud crab habitat is in accordance with [16] stating that fisheries production in Karimunjawa is decreasing due to imbalance between efforts to use and to conserve fish habitat.…”

The mangrove area in Segara Anakan lagoon (Cilacap, Central Java) is a good habitat for mangrove crabs and other mangrove biota life and growth. However, in recent years, the condition of the mangroves in the area has been degraded due to land conversion. This condition also occurs in the production of mangrove crabs in the Cilacap Regency which has decreased (2012-2017 production data). Good management efforts of the mangrove forests will also have a good impact on the growth and production of these biota in nature. This study aims to create a dynamic model of mangrove crab habitat management at Segara Anakan Lagoon in order to increase the optimization of mangrove crab production in that regency. The study method used was a dynamic systems approach that considers the relationship between crab production and the conversion of mangrove land. The results of the study showed a model of the relationship between mangrove crab production and changes in mangrove area in the Segara Anakan area with the equation: Y = 14951X − 88357 (R2 = 0.5382), with structural validation as follows: land conversion increases (rice field area) (+) and then increase the income from rice fields (+). Meanwhile, land conversion reduces mangrove area (-), reduces crab habitat function (-), reduces crab catch (-), further reduces mud crab production, and finally reduces income from mud crab production (-). The validation of the model output is the average mean error (AME) of crabs at 4.93%, while the AME of mangroves is 7.38%. This model can be concluded as a valid (acceptable) model and can be continued to the simulation stage.

Sumberdaya udang tangkapan di perairan Muara Gembong mengalami penurunan, salah satu penyebabnya adalah rusaknya habitat mangrove yang berakibat habitat asuhan udang terganggu. Kawasan asuhan udang menjadi salah satu opsi konservasi yaitu sebagai sumber rekruitmen stok udang dan biota laut lainnya. Tujuan penelitian ini untuk menentukan kawasan asuhan sumber daya udang. Penelitian dilakukan di 20 stasiun pada bulan Maret, Juli, dan September 2018. Kriteria penentuan kawasan asuhan udang meliputi: Eko-biologi, Sosial-Budaya-Ekonomi, dan Integrasi Sosio-Ekobiologi. Hasil penelitian menunjukan bahwa di stasiun penelitian nomor 11 wilayah perairan Mulut Muara Kuntul, Desa Pantai Sederhana yaitu Pulau Buaya sesuai untuk calon kawasan asuhan udang. Di Pulau Buaya teridentifikasi udang pada fase larva sebanyak 2,45%, post larva 1,04-76,83% dan komposisi juvenile udang dari famili Penaeidae sebanyak 72,5%, Palaemonidae 19,65%, Atydae 7,95% dan Squilidae 3,3%. Ketersedian sumberdaya udang didukung oleh kualitas perairan, ketersediaan pakan alami, dukungan masyarakat dan pemerintah daerah. Posisi geografis Pulau Buaya pada 107°0'47,044" - 106°59'37,968" BT dan 5°58'49.431" - 6°0'51,683" LS dengan luas sekitar 42,104 Ha.

Segara Anakan is a semi-close water ecosystem which is connected to Donan River (industrial and residential areas) in the east and Citanduy River (agricultural area) in the west. Most activity in those areas can produce a waste which becomes sources of harmful pollutants to the aquatic environment. The aim of this study was to analyze the content level of heavy metals (Pb, Hg, Cu and Cd) in muscle and safety level consumption of the tank goby (<em>Glossogobius giuris</em>) in the area. This study was conducted for 4 months in June, August, September and October 2017 at the waters of East Segara Anakan Lagoon of Cilacap (Central Java Province), The heavy metal concentration in the muscle was measured by AAS (Atomic Absorption Spectrophotometer). Based on the analysis, the heavy metal contents of Pb, Hg, Cu, and Cd in the tank goby were 0-0.005 mg/kg, 0-0.044 mg/kg, 0.164-0.293 mg/kg, and 0.001-0.032 mg/kg, respectively and these contents were under the safety limit. Safety level of consumption of the fish was 837.3 g/week (for adult) and 251.2 g/week (for children).<br /><br />
