Abstract

The residue of human activities and batik industrial waste water surrounding the river will be able to increase the accumulation of chromium and to disrupt macrozoobenthic communities in the river. The aims of this study was to assess the impact of human activities surrounding the river to the macrozoobenthic communities and the accumulation of chromium in Cimanuk Lama River, Indramayu District, West Java. The study has been conducted from AprilMay 2015 based on three times sampling at three different sampling stations. The result of this study shows that the chromium accumulated in the waters of all station still meet the standard quality ranging from 0,010-0,016 mg/l, but only station 1 fulfills the standard quality for chromium accumulated in the river sediment with the range of all stations was about 11,72-46,63 mg/kg. The results also show that the community index analysis describes the change of macrozoobenthic community at all stations caused by environmental pressure, especially at the station 2 which is indicated by the highest score of Family Biotic Index. The accumulation of the chromium in the waters and the change of macrozoobenthic community structure are mostly influenced by the use of the Cimanuk Lama river long for agricultural and fisheries activities, and also batik home industry.

Abstract

The water and sediment caused by heavy metal has become a major problem in coastal areas. Heavy metals released into the water binds to particulate matter, accumulate into sediments and its predicted by the pollution assessment method. The aims of this research was to investigate the distribution and contamination levels of Pb in water and sediments of Bondet Estuary. Water and sediments samples were collected from four stations in September 2020. The monitoring data of water quality status, contamination factor (CF), and geo-accumulation index (Igeo) were used to provide a assessment of the Pb contamination. The concentration of Pb in water at all stations (0,024-0,031 mg/L) was higher than the standard surface water, with the status is lightly polluted (class B). CF index for all stations 1 ≤ CF <3 indicates moderate Pb contamination in the sediment, while Igeo for each station is <0, which means no contamination. Overall when referring to some guidelines for sediment standards, Pb concentrations at all stations were still below the standard value for sediment. This study provides a basis for assessing future conditions and risks, so that it can contribute to the management and evaluation of heavy metal contamination in the Bondet Estuary.

Abstract

Ekosistem mangrove secara ekologis berperan sebagai spawning ground, nursery ground dan feeding ground berbagai macam organisme. Salah satu biota yang terletak pada ekosistem mangrove Segara Anakan adalah Gastropoda. Fauna ini memegang peranan penting dalam jaring-jaring makanan dan proses dekomposisi. Hutan mangrove Segara Anakan mengalami perubahan akibat faktor alami (sedimentasi) dan faktor antropogenik. Jika hal ini diabaikan tentu saja akan mempengaruhi pola distribusi dan preferensi habitat Gastropoda. Tujuan penelitian ini adalah untuk mengetahui komposisi, kelimpahan, distribusi dan preferensi habitat Gastropoda pada hutan mangrove Segara Anakan, Cilacap. Penelitian dilakukan pada bulan Agustus-Oktober 2022 dengan periode pengambilan dua minggu sekali. Metode sampling yang digunakan yaitu purposive sampling. Dua pemilihan lokasi berdasarkan perbedaan karakteristik yaitu : St A (bagian timur Segara Anakan, salinitas 10-20 ‰, kerapatan mangrove Rhizophora sp. rapat, dekat dengan pelabuhan) dan St B (bagian barat Segara Anakan, salinitas 5-10‰, kerapatan mangrove Rhizophora sp. jarang, dekat dengan pemukiman penduduk). Pada setiap stasiun penelitian ditentukan lima titik pengambilan sampel, setiap titik terdapat tiga plot pengambilan sampel. Data yang diperoleh dianalisis dengan PCA (Principal Component Analysis). Berdasarkan hasil penelitian diperoleh komunitas gastropoda pada St A sebanyak 8 famili dan St B 6 famili. Famili yang paling mendominasi pada kedua stasiun pengamatan yaitu Potamididae dan Neritidae. Kelimpahan tertinggi terdapat pada St B sebesar 290 ind/m2, sedangkan St A berjumlah 180 ind/m2. Pola distribusi gastropoda termasuk dalam kriteria mengelompok dan merata. Dari hasil analisis PCA kelimpahan Gastropoda berhubungan erat dengan kandungan oksigen terlarut. Hal ini terkait peran oksigen dalam pemenuhan respirasi dan dekomposisi bahan organik. Kata kunci : Gastropoda, Mangrove, Pola distribusi, Preferensi habitat, Segara Anakan
