Judul: Study of natural fisheries management as complement of reservoir utilization for cage aquaculture (case study cirata reservoir)
Abstrak: Keberadaan keramba jaring apung di Waduk Cirata sangat mempengaruhi segala aktivitas di sekitarnya, baik dari segi ekologi, maupun ekonomi masyarakat yang berada di waduk. Keramba jaring apung adalah suatu bentuk budidaya ikan yang mmeberikan kemudahan bagi masyarakat yang ingin membudidayakan ikan tanpa harus mempunyai lahan diantara kemudahan tersebut terdapat sederetan efek yang ditimbulkan oleh keramba jaring apung jika tidak ditangani dengan baik. Diantaranya jumlah yang melampaui daya dukung kapasitas perairan, kualitas perairan yang menurun akan mempengaruhi daya tampung ikan yang berada di luar keramba jaring apung akan menyebabkan terjadinya pendangkalan akibat sisa pakan yang mengendap di dasar perairan.

Judul: Analisis Pendapatan dan Efisiensi Produksi Usahatani Budidaya Pembesaran Ikan Mas dan Nila Pada Keramba Jaring Apung Ganda (Studi Kasus Waduk Cirata Desa Bobojong Kecamatan Mande Kabupaten Cianjur)
Abstrak: Cirata reservoir is one of three reservoirs in Citarum River that has major contribution to the fisheries in West Java. Fisheries in Cirata is conducted by fish rearing (Keramba cage) double KJA. Aquaculture of KJA performed by enlargement Cyprinus carpio and tilapia. This is because those commodities were major commodities in Cirata especially Cyprinus carpio. Enlargement of Cyprinus carpio and tilapia Aquaculture was cultivated widely in Bobojong village. The Objective of this research were to identify the structure of costs and farm income from KJA enlargement of Cyprinus carpio and tilapia aquaculturein Bobojong village by using π=TR-TC method, to analyze the factors that affect farm income from enlargement of Cyprinus carpio and tilapia aquaculture in Bobojong Village by using multiple linear regressi on analysis, to analyze the efficiency of production by using MR = MC and revenue efficiency y R/C method. Based on there gressi on results obtained, the factors that affect farmers' income significantly on the 5% through significance level were the number of Cyprinus carpio production, total production of tilapia, Cyprinus carpio seed costs, the price of tilapia seed, and the price of Cyprinus carpio feed education were not affected largely for the farm income. The results obtained on the third objectives howed that production off arming aquaculture on KJA fisheries was not optimal so that the production and production inputs used need to be optimized in order to get maximum profit. Enlargement of Cyprinus carpio aquaculture and tilapia in Bobojong Village was feasible to performed because the value of R/C off farm income from cash costs and total cost was greater than one.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
