Judul: Studi Tentang Perikanan Pancing Ranggung di Tanjung Pasir, Kabupaten Tanggerang
Abstrak: Penelitian ini telah dilakukan di Tanjung Pasir, Kabupaten Tangerang pada bulan Mei hingga Juli 1991. Tujuan penelitian adalah untuk mengetahui keadaan perikanan pancing ranggung di Tanjung Pasir, Kabupaten Tangerang. Selain itu juga untuk membandingkan hasil tangkapan pancing ranggung yang menggunakan dua mata pancing dengan yang menggunakan empat mata pancing. Metode penelitian ini menggunakan eksperimental fishing dengan mengikuti trip penangkapan. Pengamatan dilakukan untuk masing-masing unit pancing ranggung yang menggunakan dua mata pancing dan yang menggunakan empat mata pancing. Data diperoleh dengan jalan mengoperasikan kedua jenis pancing tersebut secara bersama-sama. Data yang terkumpul kemudian dianalisis dengan uji kenormalan Lilliefors. Analisis selanjutnya dengan metode statistik parametrik yaitu menggunakan rancangan acak lengkap. Hasil analisis menunjukkan bahwa hasil tangkapan pancing ranggung yang menggunakan empat mata pancing tidak berbeda nyata dengan pancing ranggung yang menggunakan dua mata pancing. Hal tersebut diduga akibat pancing ranggung yang menggunakan empat mata pancing sering terbelit antar tali cabangnya....

Judul: Kelayakan Usaha Pancing Rawai di Pangkalan Pendaratan Ikan Tanjung Pasir Kabupaten Tangerang
Abstrak: The development of small scale fisheries in Indonesia is not quite grow because of difficult to getting loan. PPI Tanjung Pasir is dominated by small scale long line fisheries. The objective of this research are to describe the fishing unit, productivity and financial feasibility. This research used descriptive method. The result showed that long liner was 3-4 GT wood boat, with lenght: 7.5-10 m, width: 2-3 m, and draft 1-2 m. There were 3 fishermen in one fishing unit. The lenght of long line is 3 000-4 000 m, aproximately the number of hook were 600-1 000. Composition of long line catches were dominated by white snapper (Lates carcarifer). Productivity per trip was 28.09 kg/trip/year, boat productivity was 1.899 ton/GT/year, gear productivity (hook rate) was 0.05 fish/trip/boat, and fisherman productivity was 9.36 kg/man/trip. Based on investment analysis, R/C ratio was 1.11, payback period was 2.36 year, ROI was 42%, NPV Rp30 253 594, IRR 51.30% and Net B/C ratio was 2.01. Refers to productivity and financial analysis, Tanjung Pasir long line business is feasible to be continued and expanded.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
