Abstract

Bacterial isolate of Patin siam ( Pangasius hypopthalmus) larvae are Bacillus mycoides, Bacillus megaterium, Micrococcus sp, Acinetobacter baumannii, Pseudomonas putida, and Actinobacillus sp. Bacterial isolate identification on protein precipitation method showed prohibit value is 6,07 – 6,20 mm. Extracellular metabolite method revealed exclude value is 7,16 – 16,14 mm. Actinobacillus sp have ability for proscribe bigger than other bacteria isolate.

Abstract

Blue swimmer crab (Portunus pelagicus) are not only tasty and popular, these animals are the producers of hard shell to protect their body. From its shell waste, we can harvest chitin and process it into chitosan. As blue swimmer crabs waste is easily found in Bangka, we hope that it can be used to solve water pollution caused by heavy metals (Pb, Zn, and Cu) in many open pit areas there. The objective of this study was to evaluate effectivity of blue swimmer crabs’ chitosan in adsorbing heavy metals. This study was conducted from May to December 2010 in Sungailiat. Contaminated water from ex-mining open pit was used in this study. A 0,5%, 1% and 1,5% of chitosan was applied in degrading heavy metal. Research showed that there was a decline of heavy metal content caused by chitosan application. Its adsorbing activity was influenced by pH and temperature. We can benefit from blue swimmer crabs waste shell to improve water quality in ex-mining open pit water.

Abstract

The processing of agar produces 65-70% residu from all raw materials that are used. The residu in form of drugs or solid waste contain macro and micro nutrients which unfortunately have not been used optimally. The waste has a potential to use as an organic fertilizer. The effect of agar waste on growth of mahogany seed and physical and chemical properties of tailing were studied. Compost fertilizer was used as comparison to see the effectiveness of addition agar waste on growth of mahogany. The growth of mahogany seed was observed from height and diameter parameter, while the minerals content were measured by Atomic Absorption Spectrophotometry (AAS). The result shown thar the highest growth was achieved when mahogany was treated with 1% agar waste, while the biggest diameter was achieved with 1,5% agar waste. Agar waste treatment improved chemical properties of tailing but has not significant change on physical properties.

Abstract

Protein hydrolyzed has high protein so that can be used for food industry and also pharmacy. Existence of making product of protein hydrolyzed expected can improve fishery product become new product as food which have high protein. One of marine product which not explore yet is green cockle. It has high protein and can be made as fish protein hydrolyzed product through modification process. The aim of research are: to determine of enzyme concentration, time and hydrolysis pH for making of hydrolyzed product. Results of research indicate that best concentration of enzyme for making of hydrolyzed product is 5% (w/v), 24 hours and pH 7. Characteristic of green cockle protein hydrolyzed are: water rate is 84,44 %, dusty rate is 1,25%, protein is 11,75% and fat is 2,56%. Protein hydrolyzed product of green cockle contain of free nitrogen -amino as much as 0,88 g/100 g and also hydrolyzed degree equal to 0,47. This protein hydrolyzed product consisted of 17 kinds of amino acid.

Abstract

Bangka Belitung Islands Province is one of the tin-producing areas, where tin mining activities are always leaving degradation the soil, vegetation and wastes that are toxic, especially some heavy metals such as Pb, Cu and Zn in soil and in the former tin mine excavation called kolong. Greatly affect the quality of waste water and cause pollution, it is feared could extend to land and waters around so that endanger residents. Based on the results of research conducted on the measurement of three former tin mining at different age levels (0, ±8, and> 15 years), it can be concluded that the older age, so the content of heavy metals (Cu, Pb and Zn) is decrease. This is caused by several factors, such as the ability of aquatic plants (Lepiromia micronata) which accumulate heavy metals and other factors such as rain water dilution and precipitation. The results showed that endemic plants can absorb heavy metals. Therefore, heavy metal reduction of tin mining in Bangka Island using phytoremediation method by aquatic plant, because it is relatively inexpensive, easy and environmentally friendly.
