Abstrak: Goldband goatfish (Upeneus spp.) Is one type of fish landed in Labuan PPP. Goldband goatfish (Upeneus spp.) has economic value and are scattered throughout the Indonesian waters and is one of the target species in fishing activities. The purpose of this study was to determine the seasonal patterns of fish abundance and their Goldband goatfish arrest and estimating potential area of sustainable fish resource in PPP Labuan, Banten to know the status of utilization and policy making in the management of fish resources in the sustainable potential Goldband goatfish by PPP Labuan, Banten. The experiment was conducted in the District of PPP Labuan Labuan Banten Pandeglang. Based on the results of this study describe the overall condition of fish stocks Goldband goatfish overfishing that has not undergone biological and economical overfishing so that appropriate management strategies are needed so that resources can be exploited Goldband goatfish optmal. The addition of fishing effort should be made in the summer fishing season as June and August. The optimum efforts to maximize the economic benefits recommended by the bioeconomical model trips per year by 1057 with the arrest quota of 21481 kg per year.

Judul: Potensi Sumber Daya Ikan Selar Kuning, Tembang, dan Tongkol di Selat Sunda yang Didaratkan di PPP Labuan, Banten
Abstrak: Pelagic fishery potential in the Sunda Strait is the highest compared to other fisheries. The dominant pelagic fish caught were yellowstripe scad, fringescale sardinella, and thonine orientale. Pelagic fish is a economic important, that facing arrest are increasing every year and it is feared to overfishing. The aims this study are to assess the utilization condition of pelagic fish in PPP Labuan, Banten especially about biological and economic aspects. The method used to determine potential is through the selection correctly of surplus production. Maximum sustainable yield (MSY) and maximum economic yield (MEY) are 1875.02 ton/year dan 1874.71 ton/year for yellowstripe scad, 3311 ton/year dan 3303 ton/year for fringescale sardinella, also 1721.17 ton/year and 1710.64 ton/year for thonine orientale. Actual catche efforts of yellowstripe scad, fringescale sardinella, and thonine orientale has greater than optimum efforts, so that indicated has been biological and economic overfishing. Economic rent on the actual condition of the third kind of fish is lower than the economic rent of MSY and MEY conditions. This condition can be caused by the rate exploitation of the three kinds of fish exceeding the optimum exploitation (> 0.5) so it had overexploited. Economic rent on the actual condition is lowest because degradation of the fish resources has increased every year. The better utilization is MEY condition because these have maximum benefit. Management plan of pelagic fish in PPP Labuan are reduction fishing effort, selectivity of fishing gear, and setting size of the fish can be caught.

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.
