Judul: Supply Chain Systems and Tuna Loin Handlings in the Maluku Waters’s.
Abstrak: Fishing operation pattern in Maluku waters are highly dependent on natural conditions and others supporting technical factors such as fuel supply and other operational capital which generally unstructured and unmeasureable fishing operation management pattern. One important factor in determining quality control process is supplying-chain factor, i.e. loin tuna distribution which ranging from fish hooked on the ship until the receiving product by the consumer. The objectives of this study is to describe loin tuna supply chain system in Maluku. The supply chain was analyzed by using black box diagram system approach and market integration model used to identify a valuate the relationship of each supply chain component with destined market. The results showed that there is no market integration between Japanese markets and Maluku, but there is long term cooperation between American market and Maluku..

Judul: Katalis Eterifikasi Gliserol Berbasis Poli–(asam stirena sulfonat) dari Limbah Styrofoam.
Abstrak: Styrofoam waste can be converted to poly–(sulfonate styrene acid) (PSSA) that can be used as catalyst. The objective of this research is to get PSSA that can catalyze the etherification of glycerol and benzyl alcohol. The styrofoam waste was converted to PSSA by reacting with H2SO4 98% (as sulfonation agent) and P2O5 (as sulfonation catalyst) at 40 °C for 6 hours. Characterizations of PSSA included functional groups, sulfonation levels, water swelling, and thermal stability. The yield of PSSA was 40-55%. The success of sulfonated polystyrene was shown by –SO3H group absorption at 1157.29 cm-1. Etherification of glycerol and benzyl alcohol using PSSA catalyst was conducted at 110 °C for 12 hours. The conversion in producing mono–benzyl ether glycerol was 8.10%, 1,3–dibenzyletherglycerol 2.60%, and dibenzyl ether 9.80%. Therefore, the PSSA can be used as etherification catalyst.
