Abstract

Waters of  Bangka Island condition increasingly polluted and marine ecosystems all the time more damage due to the impact of offshore tin mining. Offshore tin mining destruct marine ecosystem and always leaves the turbidity and high sedimentation rates in the ocean. Mining of floating cause the seabed sediments are mixed with sea water, as a result suspended matter content become higher and spreading by ocean waves into seagrass ecosystems. High sedimentation rate if it exceeds the threshold, in addition to inhibiting seagrass photosynthesis, can also cause death and loss of seagrass. Seagrass has several important functions in coastal and marine areas, such as spawning, protection and enlargement ground of marine life. Seagrass bed has a very important role, therefore the seagrass damage that occurs needs to be fixed, one of the method is seagrass transplantation as restoration efforts. The aim of research was to determined the efficiency of seagrass transplantation method in accordance with waters of Bangka Island,at  tin post mining in the sea post. Seagrass transplantation method used as experimental in this research is a method of burlap sacks and Sprig Anchor. The results showed that the method is more suited to waters of Bangka Island. It is because Bangka island waters classified as fast-flowing waters. The method of burlap sacks is a method that fill sacks with substrate, so could be used as retaining current.

Abstract

Matras waters receive input of pollutants from tin mining activities. Heavy metals are toxic and carcinogenic to aquatic biota. Sediment is a carrier of heavy metal pollutants and can act as a “sink” and a “source”. Heavy metals in sediments can reflect the condition/quality of the aquatic system. The purpose of this study was to examine the contamination and ecological risk of heavy metals Cd, Pb, Cu, and Zn in the sediments of Matras waters, Sungailiat, Bangka Regency. Heavy metal test using atomic absorption spectrophotometer (AAS). The concentrations of heavy metals Cd, Pb, Cu, and Zn obtained ranged from 0.02-0.06 mg/kg (average 0.04 mg/kg), 0.12-0.18 mg/kg (mean- average 0.15 mg/kg), each station 0.01 mg/kg (mean 0.01 mg/kg), and 0.54-1.34 mg/kg (mean 0.92 mg/kg ). CF, I-Geo, PLI, and RI values for Cd, Pb, Cu, and Zn metals obtained in Matras water sediments showed low contamination levels (CF<1), not polluted (Igeo 0), not polluted (PLI < 1), and low ecological risk (RI < 150). The EF value obtained indicates the heavy metals Cd, Pb, Cu, and Zn in the Matras waters mainly receiving input from anthropogenic sources (EF value> 1.5). The low ecological risk status which is reinforced by the low values of CF, I-Geo, and PLI indicates that the negative potential of metals to biota is also low.  Perairan Matras menerima masukan bahan pencemar dari aktivitas penambangan timah. Logam berat bersifat toksik dan karsinogenik terhadap biota akuatik. Sedimen merupakan pembawa polutan logam berat dan dapat berperan sebagai “sink” and “source”. Logam berat pada sedimen dapat merefleksikan kondisi/ kualitas sistem akuatik. Tujuan penelitian ini untuk mengkaji kontaminasi dan resiko ekologi logam berat Cd, Pb, Cu, dan Zn pada sedimen Perairan Matras, Sungailiat, Kabupaten Bangka. Uji logam berat menggunakan metode spektrofotometer serapan atom (SSA). Konsentrasi logam berat Cd, Pb, Cu, dan Zn yang diperoleh berkisar antara 0,02-0,06 mg/kg (rata-rata 0,04 mg/kg), 0,12-0,18 mg/kg (rata-rata 0,15 mg/kg), setiap stasiun 0,01 mg/kg (rata-rata 0,01 mg/kg), dan 0,54-1,34 mg/kg (rata-rata 0,92 mg/kg). Nilai CF, I-Geo, PLI, dan RI untuk logam Cd, Pb, Cu, dan Zn yang diperoleh pada sedimen Perairan Matras menunjukkan tingkat kontaminasi rendah (CF<1), tidak tercemar (Igeo 0), tidak tercemar (PLI <1), dan resiko ekologi rendah (RI < 150). Nilai EF yang diperoleh mengindikasikan logam berat Cd, Pb, Cu, dan Zn perairan Matras utamanya mendapat masukan dari sumber antropogenik (nilai EF>1,5). Rendahnya status resiko ekologi yang diperkuat dengan rendahnya nilai CF, I-Geo, dan PLI menunjukkan potensi negatif logam terhadap biota juga rendah.

Abstract

Coral reef ecosystem has many biological, ecological, and economical functions to the universe. This ecosystem provides shelter, food, and home for many marine organisms and together they perform diverse and rich ecosystem. However, this diverse ecosystem is very susceptible to environmental change, such as climate change, ocean acidification, and other anthropogenic impact. When reef-building coral could not stand with harsh condition they will eventually die. We assume that anthropogenic stressor such as turbidity, terrestrial runoff, and sedimentation is the main problem here, because of high number of tin mining activities. Bangka and Belitung Islands are huge tin producer and has been exploited heavily by the legal and illegal miner company. The purpose of this study is to investigate the live coral cover in Central and South Bangka by using the line intercept transect to calculate the live coral, died coral, and algae in each stations. The results showed that the coral cover in Central Bangka and South Bangka has fair condition (25-40% of live stony coral). Value of live and dead coral cover was 40% with Semujur and Ketawai represent the coral cover in Central Bangka. While South Bangka has slight (1-2%) difference of live coral, dead coral, and algae cover. High number of dead coral mainly composed by dead coral overgrown by algae, allegedly caused by high turbidity and sedimentation from the anthropogenic stressor. Ekosistem terumbu karang mempunyai fungsi biologi, ekologi, dan ekonomi yang bermanfaat bagi manusia. Ekosistem ini menyediakan tempat berlindung, makanan, dan rumah bagi organisme laut dan membentuk suatu ekosistem yang kaya dan beragam. Namun, ekosistem ini sangat rentan terhadap perubahan lingkungan, sepertiiklim, asidifikasi, dan dampak lain yang dilakukan manusia. Ketika terumbu karang tidak mampu bertahan dengan perubahan lingkungan yang ekstrim mereka akan mati. Kami menduga bahwa dampak antropogenik seperti turbiditas, runoff dari darat, dan sedimentasi merupakan penyebab utama kerusakan terumbu karang, karena banyaknya aktivitas penambangan. Kepulauan Bangka belitung adalah penghasil timah terbesar dan telah dieksploitasi oleh penambang timah legal maupun ilegal. Tujuan dari penelitian ini adalah untuk mengetahui tutupan karang hidup di Provinsi Bangka Tengah dan Bangka Selatan dengan menggunakan metode traksek garis. Hasil menunjukkan bahwa terumbu karang di Bangka Tengah dan Selatan termasuk kategori sedang (25- 40% tutupan karang). Tutupan karang hidup dan karang mati di Bnagka Tengah sebesar 40% dari hasill pengamatan di Semujur dan Ketawai. Sedangkan nilai tutupan karang hidup, karang mati, dan alga di Bangka Selatan mempunyai angka perbedaan yang rendah (1-2%). Tingginya tutupan karang mati tersusun oleh karang mati yyang ditumbuhi alga yang disebabkan oleh turbiditas dan sedimentasi.

Abstract

Tuing waters become the main catchment area of ​​squid in Bangka Regency. Bait is one important factor in squid fishing trying to captivate the target with something as its prey is in the form of smell, taste, movement, shape and color both artificial baits and natural baits. The objective of the study was to analyze the catch of squid with different baits. The research was conducted in May 2016 in Tuing Waters of Bangka Regency. The method used in this research is the trial of catching the squid. Analysis of data used using Mann Whitney test. Taking data 4 times a month using squid fishing line. The results obtained between fishing with artificial feed and natural baits differ significantly because of Z count (2.17)> Z table (1.96), then H0 is rejected. This is because the waters of Tuing in May 2016 are not the season for the cultivation of the umi-squid. The catching season of squid occurs in November-Desenber in Tuing Waters. Squid is highly associated with environmental factors such as salinity, temperature and depth of water. Chemical Physical Factors The aquatic waters against the catch of squid.
