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

Tapah fish (Wallago leerii), one of Bangka's local fish species found only along the Jeruk River in Tanah Bawah Village, is now threatened with extinction due to fishing pressure and ecological pressure caused by human activities. Moreover, the trend of environmental degradation due to the rampant tin mining on Bangka Island is feared to threaten the original habitat of tapah fish. Tapah fish is one of the most economically important fish because it is not only very popular with the public due to its large size, good taste and savory, but also because of its nutritional value and high price. So far, the supply of tapah fish has only been obtained from natural catches. If this is done continuously due to higher demand, it will threaten the sustainability and even extinction of tapah fish. This condition will also have an impact on the economy of people who depend on river fish catches, especially tapah fish. Proper management of tapah fisheries is needed so that its utilization can be sustainable and optimal and sustainable, one of which is through domestication efforts. This Ipteks for Communities (IbM) program tries to introduce a simple domestication technology that has been tested in the waters of the Kampar River in Riau. The activity begins with rearing tapah fish fry from nature and then enlarging them to a consumable size. Proper maintenance techniques include acclimatization techniques, selecting the right type and dose of feed to stimulate growth and monitoring the water quality of the cultivation container.

Abstract

Desa Tanah Bawah memiliki potensi lahan dengan ketersediaan sumber air yang melimpah. Selain dapat dimanfaatkan untuk pemenuhan kebutuhan air baku konsumsi, mandi dan cuci, potensi lahan perairan dapat dioptimalkan untuk pengembangan budidaya perikanan. Budidaya polikultur diharapkan dapat memberdayakan masyarakat serta menjadikan Desa Tanah Bawah berpotensi menjadi desa mandiri pangan dari produksi padi sawah dan hasil perkebunan yang melimpah serta perikanan budidaya. Teknologi budidaya polikultur dinilai ramah lingkungan karena didesain untuk meminimalisir limbah buangan sisa pakan yang tidak termanfaatkan. Daya dukung lingkungan perairan bisa tetap dipertahankan. Selain itu secara hitungan ekonomi, pilihan teknologi budidaya polikultur dengan sistem KJA dinilai sangat menguntungkan karena hasil panen yang lebih tinggi dibandingkan dengan sistem monokultur. Hasil panen ikan yang berlipat dari dua komoditas yang dibudidayakan (ikan nila dan ikan mas), otomatis akan mendatangkan keuntungan yang berlipat juga walaupun dengan input biaya produksi yang sama, karena efisiensi dan pemanfaatan pakan yang optimal. Pelaksanaan IbM ini diharapkan dapat meningkatkan ekonomi masyarakat secara signifikan dan dapat berkelanjutan.
