Judul: Analisis Risiko Produksi Pembenihan Ikan Arwana Super red di PD Dian Ardyka, Pontianak, Kalimantan Barat.
Abstrak: Fishery sector contributes an important contribution in economic condition of Indonesia, one of which is the increase of ornamental fish export volume in increasing the growth of gross domestic product in Indonesia. Arwana super red is one of ornamental fish that is put into the category of export comodity in Indonesia. Arwana super red comodity experiences fluctuation every year. This shows that there is a risk in the business of arwana super red. This risk is also faced by PD Dian Ardyka, one of the biggest arwana super red export companies in Pontianak. The aim of this research was to find the appropriate strategy to overcome the risk in seed production of arwana super red in PD Dian Ardyka by identifying the risk source and making the risk map. The result of this research indicated that the company faced problems when the age of seed was still young. Moreover, the company also faced problems like disease attact, deformed seed, and broken egg on the seed. The alternative strategy proposed in the risk source handling was by using the approach of preventive strategy and mitigation.

Judul: Analisis Risiko Produksi Pembesaran Ikan Hias Neon Tetra (Studi Kasus di Pengusaha Bapak Rodi, Kecamatan Bojongsari, Kota Depok)
Abstrak: Indonesia is the archipelago country and well-known in the world, So it supports the fisheries sector and has the potential for economics development as maritime country and nation. One of these, is the non-consumption of fishery products business in Indonesia, in particulary is a commodity of ornamental fish. It has developed quite rapidly besides having promising prospects economically. The Objective of this study is to identify a source of risk production and to analyze probability and impact of risk production in the rearing operational business of ornamental fish neon tetra owned by Mr. Rodi. The analytical method used is the analysis of risk management and risk analysis based on the size of the Expected Return approach, variance, standard deviation, and coefficient of variation. The result Based on the risk assessment on the production of ornamental fish rearing business neon tetra obtained the expected return value is 84.77 for a single period. That Means is Mr. Rodi can expect as much the result of the acquisition of 84.77 per cent survival rate in this enlargement effort for each harvest period. The coefficient of variation values obtained results of 0.20. In other words, for every one percent success rate ornamental fish neon tetra obtained will have a risk of 0.20 percent at the time of production risk. Some things that can be done is to make investments in the form of a purchase thermometers and pH meters tool that checks the temperature and pH can be done routinely.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
