Abstrak: Construction of Cirata lake beginning work as Hydroelectric power, its potential great society exploited as Floating Cage Net however gradually Floating Cage Net not be felt by people around and switch caught fish outside floating cage net, increasing activity the exploitation in Cirata lake will impact of fish habitats who lived outside floating cage net. The aim of this research wasto observe fish diversity outside floating cage net with knowing the catch of fisherman and fish are caught and identify native fish species. The result showed most caught of fisherman is nila fish (Oreochromis niloticus) is 424 kg (68,1%) and the most fishing gear used by fisherman is gillnet. The value of index (H’), (E), and (C) consecutive is 1,28; 0,58; and 0,43. Based on the value of that index in waters Cirata Lake, fish who dominated in Cirata Lake is Nila Fish (Oreochromis niloticus).

Abstrak: The research of the sustainable management model’s design of Reservoir Fisheries floating cage (Reservoir Case Cirata, West Java) aims to calculate the carrying capacity, make its institutional model, build dynamic system model and assess the sustainability of the reservoir management of floating cage based aquaculture in Cirata Reservoir. The calculation of the pollution load and capacity of assimilation is used to calculate its carrying capacity and Interpretative Structural Modeling (ISM) is used to create institutional. Furthermore, Powersim software is used to create dynamic models and Rapfish used to assess the status of sustainability in the management of Cirata Reservoir. This study shows the status of water quality in Cirata reservoir has been low into high polluted (based on water quality classification class B PP 82-year-2001), the carrying capacity of the reservoir parameters in Cirata based on TSS, BOD, COD, PO4, NO3, NO2, Fe, Cd, Zn, and Mn parameter have passed the threshold of the standard quality of water in the river. The ideal reservoir management involves the central government (Ministry of Forestry), Cirata Reservoir Management Agency, Department of Fisheries and Marine West Java Province and the Ministry of Fisheries and Marine. The population growth is the factor of problem in the utilization of Cirata Reservoir. The problem follows the basic pattern of boundary dynamic model for success, tragedy of the common and shifting of the burden, with the dominant building block is reinforcing. The increased activity of the population (KJA, industry, agriculture, livestock, forest encroachment) increased sedimentation and pollution balance the functions of ecological, economic and socio-cultural. Ecology aspect is the weakest aspect in the sustainable management of Cirata Reservoir. Socio-cultural aspect is the dominant aspect as a major capital in the intervention of four other aspects. (economic, legal-institutional, technology / infrastructure and ecology).

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.
