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: Penilaian Unit Penangkapan Pancing Rumpon di Palabuhanratu, Kabupaten Sukabumi, Jawa Barat
Abstrak: Tuna total production with rod fishing increase 0.73% in 2011, and total of rod fishing unit increase 1.55% in the same time. Technical and economical analysis must be done for we know how the feasibility of rod fishing unit’s business. The objective of the research is to describe the rod fishing unit, to calculate the benefit, and the investment of rod fishing unit’s business in Palabuhanratu waters. The research is case study of rod fishing unit’s business. Data analysis used description, technical and financial analysis. There are four types of rod fishing, those are troll fishing, pancing jerigen, pancing layanglayang and hand line. The rod fishing is not difficult in operation. Business of the rod fishing unit can give a profit Rp 67,245,500.00 and payback period is 4.2 years. The value of NPV is more than 0 (zero), Net B/C is more than 1 and IRR is more than value of interest rate. The business of rod fishing unit is not sensitive to the fuel’s price increasing. The decision makers can help the fishermen to improve their capital from finance institution, and do the detail technical analysis about rod fishing unit operation and its influence to stock equilibrium

Judul: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
