Abstract

Banyaknya aktivitas penambangan timah di Bangka Belitung menyebabkan pencemar logam berat terakumulasi ke badan perairan, salah satunya adalah kegiatan penambangan timah di perairan Tanah Merah. Penelitian dilaksanakan pada bulan April - November 2019 di Pantai Tanah Merah Kabupaten Bangka Tengah. Tujuan penelitian ini yaitu mengetahui konsentrasi polutan logam berat (Pb dan Cu) di perairan tersebut. Metode penelitian dilakukan dengan cara purposive sampling dan melakukan analisis logam berat (Pb dan Cu) serta pemodelan menggunakan MIKE21 untuk mengetahui persebarannya. Hasil menunjukkan bahwa model sebaran polutan logam berat sangat dipengaruhi oleh kondisi arus yang dominan berupa arus pasang surut. Model sebaran Pb dan Cu di perairan terkonsentrasi di area sumber pencemar yang telah berada di atas baku mutu air laut dan semakin kecil menjauhi sumber lokasi pertambangan sesuai dengan arah arus perairan. Pemodelan menunjukkan bahwa jarak sebaran terjauh dan arah dari polutan logam berat (Pb dan Cu) di perairan, masing-masing sebesar 7,51 mil (12.086 meter); 6,17 mil (9.929 meter) dengan waktu tempuh 68 dan 62 hari dan arah polutan 330oU. Pola sebaran logam berat yang sangat luas ini mengindikasikan bahwa aktifitas pertambangan tidak direkomendasikan pada lokasi yang berdekatan dengan fishing ground  karena efek sebaran logam berat yang berbahaya akan terakumulasi pada biota bahkan ekosistem perairan.

Abstract

The intertidal zone is an area that is located at the very edge of coastal and marine ecosystems and borders on land ecosystems. It is feared that continuous and environmentally unfriendly fishing will have an impact on the sustainability of bivalves. This research was conducted from February 2021 which aims to determine the diversity of bivalves and the relationship between diversity and environmental parameters. Bivalves data retrieval using a systematic random method consisting of live bivalves and dead shells. Data retrieval is divided into 4 stations, where each station consists of 3 substations. The results obtained 8 species of bivalves that are still alive from 3 families and a total of 143 individuals. Dead shells were obtained by 9 species from 7 families. The highest bivalves density was at station 1, which was 6.21 individual/m2, while the lowest was at station 3, which was 2.44 individual/m2. The highest bivalves diversity was found at station 2 with an H value of 2,05 and the lowest was at station 3 with a value of H'1,66. The index of bivalves diversity on the coast of Pangkalpinang City was in the moderate category due to excessive ecological pressure that could reduce the abundance of organisms and disturb the balance of the ecosystem. The results of principal component analysis (PCA) showed that the density of bivalves was positively correlated with clay, BOT, and TSS. While the diversity of bivalves is influenced by temperature, pH, and salinity.

Abstract

The Province of the Bangka Belitung Islands has an ocean area of 79.9% which has the potential for fisheries and tourism as well as tin mining in the sea. This research was conducted in October 2020 in the coral reef ecosystem of Pemuja Island (near to the coastal) and Malang Duyung Coral (far to the coastal), West Bangka Regency. The method used is Line Intercept Transect (LIT). The results showed that the condition of the coral reefs on Pulau Pemuja was categorized as "damaged" with a live coral cover of 16.50% which was estimated to be due to the impact of tin mining in the sea, which was marked by a high mud cover (silt) of 48.698%. Coral Mortality Index (IMK) value of 0.75 which indicates the number of corals that died due to mud cover. The condition of coral reefs in Malang Duyung is in the "Good" category with live coral cover of 69.17%. Malang Duyung coral reefs are still affected by mining, which is indicated by the presence of a mud cover of 10.833% while the IM value of 0.15 also indicates that dead coral is still being found. The results showed that the composition of dead coral covered with is an impact of offshore tin mining. Mining locations near the coastal area have a greater impact than those far from the coastal.
