Abstract

Study of copper (Cu) content in water, sediment, and Blood Clam (Anadara granosa) was conducted in coastal waters of Bedono, District Sayung, Demak district in 2010 and 2011. This study was done because coastal waters of Bedono (such as rivers and river Sayung Gonjol) functioned as the disposal trajectory by the industrial area located along the highway Semarang - Demak. This study aimed to analyze the heavy metal content of Cu in coastal waters and Rivers Sayung and River Gonjol, District Sayung, Demak. The study was conducted during low tide conditions (in 2010) and high tides (in 2011). The results showed that in 2010, the copper content in water of River Sayung ranged from 0.003 to 0.056 mg/l, whereas in the River Gonjol, copper content ranged from not detected - 0.026 mg/l. In 2011, copper content in water is not detected, either in the River Sayung and in the River Gonjol. Copper content in the sediment of River Sayung ranged from 4.89 to 28.75 mg/kg, and in River Gonjol from 18.77 to 71.28 mg/kg (in 2010). In 2011, copper content in the sediment of mouth of River Sayung ranged from 16.1 to 25.57 mg/kg, and in the mouth of River Gonjol ranged from 16.69 to 52.72 mg/kg. In 2010, copper content in the soft tissues of the blood clam in the mouth of River Sayung was 29.86 mg/kg, and at 31.2 mg/kg in the mouth of River Gonjol. Meanwhile, in 2011, copper content was not detected in blood clams. Overall, copper content in water, sediment, and blood clams were still below the threshold quality standard set by each authority.

Abstract

Mangrove merupakan salah satu ekosistem pesisir yang mempunyai peranan penting di daerah estuari. Habitat mangrove sangat rawan terkena pencemaran logam berat, baik yang berasal dari laut maupun dari daerah darat. Rhizophora mucronata merupakan spesies mangrove yang hidup di daerah aliran sungai sebagai mayor dengan populasi terbanyak dan paling sering ditemukan, sedangkan Pb adalah salah satu polutan logam berat yang paling banyak dilepaskan oleh usaha industri. Tujuan dari penelitian ini adalah untuk mengetahui seberapa besar tingkat pengaruh pemberian logam berat Pb pada media lingkungan terhadap akumulasinya pada akar dan daun serta pertumbuhan anakan mangrove Rhizophora mucronata. Penelitian dilakukan dengan metode eksperimental selama 40 hari, dengan pemberian konsentrasi Pb 0,1; 1; 10; dan 100 ppm, ditanam di dalam  pot ember berukuran diameter 50 cm dan tinggi 30 cm, di dalam rumah kaca yang berukuran 5,5 x 2 x 1,5 m. Hasil penelitian menunjukkan bahwa pemberian konsentrasi Pb yang berbeda tidak setabil di akar maupun di daun, ini memperlihatkan bahwa konsentrasi perlakuan logam berat tidak dapat mencerminkan tingkat akumulasi logam berat pada Rhizophora mucronata. Hasil uji GLM (General Linear Model) dari pengolahan data spss pemberian Pb dengan konsentrasi yang berbeda tidak berpengaruh nyata terhadap pertumbuhan anakan mangrove Rhizophora mucronata (p ≥ 0,05) selama 40 hari penelitian.

Abstract

Mud crab is one of fishery commodities which is important in Indonesia . The high demand for mud crabs needs to be balanced with the right management strategy,  so that the population will not extinction.  Penikel Village, Cilacap is one of the fishing villages which catch mud crabs because of the high demand in the big cities such as Jakarta, Bandung and Bali.  The purpose of this study is  to determine the population and growth patterns of mud crabs in the Panikel Village, Kampung Laut District, Cilacap. The location of the study was determined by purposive sampling. Wadong and bubu are fishing tools to catch mud crabs. Sampling 67 mud crabs was carried out  on Juni 2016, after that, measurement of length, carapace width and total weight were carried out. Regression analysis between carapace width and total weight and condition factors were carried out to determine growth patterns. Based on the research, the average value of the S. serrata   length was 63.94±11.31 mm while the female one was 70.29±14.57 mm. The average value of carapace width is 92.28±15.51 mm (male) while for female sex was 98.71±18.38 mm. The average weight of S. serrata male crabs was 190.31±118.43 mm, while those of female sex were 210.77±120.93 mm. Furthermore, based on the analysis of the relationship between the length of weight found negative allomatric growth pattern with the value of the condition factor included in the low category both for male sex 0.73-1.93 and for female sex 0.59-1.66.  The low condition factor shows that the condition of Segara Anakan waters especially Penikel Village does not support the growth of mud crabs (S. serrata). Kepiting bakau (Scylla serrata) merupakan salah satu komoditas perikanan yang terpenting di Indonesia.  Besarnya permintaan  kepiting bakau yang tinggi perlu diimbangi dengan strategi pengelolaan yang tepat agar populasi tidak punah. Desa Penikel, Cilacap merupakan satu desa nelayan yang banyak menangkap kepiting bakau karena tingginya permintaan di kota besar seperti Jakarta, Bandung dan Bali. Tujuan dari penelitian ini untuk mengetahui populasi dan pola pertumbuhan kepiting bakau di Desa Panikel, Kecamatan Kampung Laut, Cilacap. Penentuan lokasi penelitian dilakukan secara purposive sampling. Wadong dan bubu merupakan alat tangkap untuk menangkap kepiting bakau. Pengambilan sampel kepiting sebanyak 67 individu  dilakukan pada bulan Juni 2016, setelah itu dilakukan pengukuran panjang, lebar karapas serta berat total. Analisa regresi kurva antara lebar karapas dan berat total serta  faktor kondisi dilakukan untuk mengetahui pola  pertumbuhan. Berdasarkan penelitian diperoleh nilai rata-rata panjang kepiting bakau S. serrta jantan adalah 63.94±11.31 mm sedang untuk yang betina adalah 70,29±14.57 mm. Nilai rata-rata lebar karapas adalah 92.28±15.51 mm (jantan) sedang untuk jenis kelamin betina adalah 98.71±18.38 mm. Rata-rata berat kepiting jantan S. serrata adalah 190.31±118.43 mm, sedangkan yang jenis kelamin betina adalah 210.77±120.93 mm. Selanjutnya berdasarkan analisa hubungan panjang berat ditemukan pola pertumbuhan allomatrik negatif dengan nilai factor kondisi termasuk dalam katagori rendah baik untuk jenis kelamin jantan 0,73?1,93 maupun untuk kelamin betina 0,59?1,66.  Rendahnya factor kondisi menunjukkan bahwa kondisi perairan Segara Anakan khususnya Desa Penikel tidak menunjang bagi petumbuhan kepiting bakau (S. serrata).
