Abstract

Nudge well is one of pure water supplying tools that is used by Indonesian to fulfill their needs. Disadvantage of using nudge well standard water from soil water is contain of high Fe. This research method was decreased the Fe concentration in water, using aeration process with pump, filtration with sand filter and combination. The result shown that Fe concentration rate in well water before and after, processing could reduce Fe 1,25 mg/l (29,32%), filtration 2,42 mg/l (57,04%) and their combination is 3,65 mg/l (85,83%). This research conclusion was the effective management could applying to inhabitants in diminish Fe concentration from well at Pelabuhan Pangkalbalam was the mixture between aeration processing and filtration

Abstract

Penambangan timah yang dilakukan di Bangka dalam waktu yang sangat lama mengakibatkan terjadinya perubahan ekologi perairan. Perubahan ekologi perairan berdampak terjadinya perubahan lingkungan secara tidak langsung akan mengakibatkan perubahan genotip dan fenotip organisme perairan. Penelitian ini dilakukan untuk mengetahui ikan yang dominan ditemukan di kolong pascatambang timah pada umur kolong 0, 5, 10, 15, dan 20 tahun. Ikan yang dominan ditemukan akan diamati fenotipnya dan kemudian dianalisis variasi genetik yang terjadi melalui analisis elektroforesis. Hasil penelitian menunjukkan terjadinya perubahan warna pada ikan sepat rawa yang dominan ditemukan. Warna ikan sepat rawa mengalami perubahan dari hitam gelap menuju hitam agak putih atau cerah. Selain itu terjadi variasi protein dari hasil analisis elektroforesis yang menunjukkan bahwa umur kolong mempengaruhi ekspresi protein dari ikan tersebut

Abstract

Kegiatan simulasi pengelolaan perikanan berkelanjutan di TWP Padaido sangat bermanfaat untuk meningkatkan kesadaran masyarakat nelayan akan pentingnya nilai-nilai konservasi. Simulasi ini diarahkan untuk menemukenali kearifan lokal serta memberikan wawasan kepada masyarakat nelayan tentang pentingnya daerah perlindungan laut (DPL) di lokasi terumbu karang dan lokasi penangkapan alternatif, pembatasan jumlah tangkapan dan ukuran ikan, pembatasan jumlah alat tangkap dan ukuran mata jaring, serta penguatan kelembagaan dengan unsur 3 tungku. Kegiatan simulasi ini dilaksanakan di Desa Sasari serta dapat dipraktekan wilayah lain di Indonesia dengan memperhatikan kondisi sosial masyarakat setempat dan pola-pola pemanfaatan sumberdaya yang sudah berlangsung

Abstract

Islands Province of Bangka-Belitung as the largest tin producers in Indonesia, also has good potential for fisheries. Ocean territory which covers about 79.9% of land area, creating a potential fishing area to fishermen in this province. Act. 32 Year 2004 regarding Regional Autonomy and the Minister of Industry and Trade Decree No. 1999 Year 1999 which states categorized as tin-free goods, make a lot of social changes in society Bangka Belitung. Exploit tin, become a tempting option for the community. Fishermen, as a part of society, as actors fishing, faced with the choice to remain to be a fisherman or turned into tin floating-miners (TI Apung)

Abstract

Temilok (Bactronophorus thoracites) is one of Teredinidae or family of wood-borer shellfish in fact have a fairly high polysaccharide content, particularly interesting source of glycogen. The object of this experiment is to investigate the impurity contents (nitrogenous compounds and nucleic acids) of extracted glycogen from low quality of temilok based on Nicoletti and Baiocchi glycogen polysaccharide extraction patent method by comprising boiling the whole tissue in an aqueous solution of 40% potassium hydroxide (KOH) and treated with 12% cationic resin Amberlite IR-120 carried out for 16 hours under stirring at room temperature, and the ability of the extracted glycogen as co-precipitant in the precipitation of deoxyribonucleic acid (DNA) of human femur. Nitrogen and nucleic acid content of extracted glycogen were spectrophotometrically measured at 260 nm, 280 nm and 320 nm. Extracted glycogen samples was characterized by determining the glucose content quantitatively using phenol-sulphate method which measured spectrophotometrically at 490 nm . The nitrogen content of extracted glycogen was about 0,8%, yield about 6,5% glycogen characterized as the lowest nucleic acids content i.e 0,07 mg/mL. In order to asses the ability of the extracted glycogen as carrier or co-precipitant of low copy number DNA, we added 20 µL the 2% solution of the extracted glycogen into first step of femur DNA procedure of precipitation. Results revealed that by adding the extracted glycogen solutions, the yield of DNA were not significantly affected at the level of 0,05 though the yield of DNA decreased against blanko about 0,005 ng/µL of 0,0401 ng/µL
