Abstract

Local fisherman communities in Bangka regency coastal, have a clean water supply problem. They Local fisherman communities in Bangka regency coastal, have a clean water supply problem. They have to buy clean water for 2.000 IDR per 20 liters. This research about water filter effectiveness, using natural resources. Research on the effectiveness of the filter with natural materials need to be done to overcome these problems . With the experimental method, stacking filters designed with several treatment sequence. Treatment 1: rubble, fibers, quartz sand, charcoal, cotton. Treatment 2: Fine sand, gravel, palm, coconut shell charcoal, and rubble. Treatment 3: rubble, gravel, fibers, fine sand, charcoal, cotton. Of the three treatment showed no clean water quality standard approach , and among the three, treatment 2 were approaching the value of clean water quality standard.

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

Periphyton is one of organism of vegetation and animal that sticks on surface of seagrass leaves and associated with seagrass as host. Periphyton is one of component in waters productivity providers. The aims of this study are to determine the types of periphyton which sticks on the leaves of seagrass in Tukak Beach, to knowing the types of seagrass and to knowing the types of  seagrass which stuck on by periphyton. The research was conducted in May-August 2011 in Tukak Beach. The data retrieval consists of three stations, where at each station is divided into three substations, the data was taken including leaves of seagrass species and physical-chemical parameters of waters. The result of this study show that 5 species seagrass was identified which are Cymodocea rotundata, Cymodocea serrulata, Thalassia hemprichii, Enhalus acoroides dan Halodule uninervis. Periphyton was identified on seagrass leaves consisting of Fragilaria, Anabaenopsis, Diploneis, Synedra, Amphora, Nitzchia, Coleochaeta, Atractomorpha, Stylonema, Dasya, Spermothamnion and Acnanthes. Heterogenous value index (H) supreme on Thalassia hemprichii and Enhalus acoroides ranging among 2,42-2,46. Domination index (e) ranging among 0,97-0,99. Periphyton organism prefer the leaves of Thalassia hemprichii and Enhalus acoroides to stick and made as host , it cause Thalassia hemprichii and Enhalus acoroides has a width and length of leaf surface and considered condition of leaf was old.

Abstract

Tin mining in Bangka has caused a lot of damage to the environment, including rivers. The damage will affect water quality and aquatic habitat that would threaten the diversity of fish resources. This study aims to determine the effect of tin mining activities on water quality and fish species diversity. The study was conducted in Menduk River during February to May 2013 through fish sampling using gill nets with several mesh sizes. Measurement of water quality parameters was performed and analyzed using Pollution Index (PI) and an index of habitat to investigate the disturbance of habitat due to tin mining. The results showed that the tin mining affects water quality, especially the brightness, turbidity, and TSS. PI based Menduk River was declared contaminated with habitat conditions upstream in heavy interference conditions. Lowest diversity index fish in upstream and overall found 21 species of fish from 10 families in the River Menduk.

Abstract

The main potential that can be used in coastal and marine areas including fisheries, coastal aquaculture, tourism and mining of South Bangka. Region of tin mining activities in the South Bangka coastal region is also a fishing ground for fishermen to conduct fishing activities. Water quality parameters include temperature, brightness, salinity, dissolve oxygen, water flow, depth, heavy metal content of seawater and plankton. Wastes from mining activities are dumped directly in the coastal regions generally in the form of waste containing heavy metals Pb. The purpose of this study was to determine the effect of Pb waste of tin mining activities on water quality in the sea fishing area (fishing ground) squid in South Bangka regency. The method used in this research is descriptive method, which aims to make a description or picture of systematic, factual and accurate effect of Pb on sea water. Pb heavy metal content in the water was analyzed based on SNI methods by using AAS refers to the sea water quality standards for heavy marine life KepMenLH 2004 (mg / l). The results of observation can average content of Pb in the region are mining of 0.113 mg / l, while in the area which is no mining of 0,0411mg / l. So H1 received, there is the influence of mining activities on the Pb content of sea water in the area of catching squid.
