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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
