Judul: Analisis Sumber Sumber Risiko Produksi Pembenihan Ikan Patin Siam pada Pasir Gaok Fish Farm di Kabupaten Bogor
Abstrak: Siam’s catfish is potential commodity which can develop in Indonesia. This commodity has been developed by Pasir Gaok Fish Farm (PGFF). PGFF faces the production risk as indicated by the production fluctuation and enhancement of catfish seed mortality. The purpose of this study are to identify the sources of production risk, analyze the probability, impact of risks, and alternative strategies. The data was analyzed with descriptive analysis, z-score analysis, and analysis of Value at Risk (VaR). The results showed that prodution risks of siam’s catfish in PGFF are cannibalism, diseases, water quality, and human error. Probability value of each highest risk source consist of cannibalism, diseases, water quality, and human error. The impact of the each highest production risk arerisk of disease, cannibalism, water quality, and human error. Based on the probability and impact of risk, prevention strategies needed to be implemented to solve the risk of cannibalism and disease with giving fresh natural food according to the needs of fish and right time.

Judul: Analisis Risiko Produksi Pembenihan Ikan Lele Sangkuriang Pada Saung Lele di Kampung Jumbo Sukaraja Kabupaten Bogor
Abstrak: Catfish was one of the consumption fish that has been cultured in Indonesia which has good prospect. The high number of catfish consumption demand, causing the request of catfish seed increasing. Bogor regency was the largest catfish-producing region in the province of West Java and has been designated to be regional aquaculture minapolitan region. Bussiness who work in the breeding of catfish om Bogor regency was Saung Catfish. Entrepreneur was faced with the SR fluctuation problem that indicate a risk of production. In identifying the sources of risk was used descriptive method. Quantitative methods used in counting probability using the Z-score and calculate the impact of using VaR. Sources of production risks contained in catfish hatchery business Sangkuriang at Saung Catfish were pests, disease, water quality, and cannibalism. The analysis result of the probability or the possibility risk arise, i.e. : 1) the pest by 35.6 percent, 2) disease of 29.1 percent, 3) water quality by 40.5 percent, and 4) cannibalism of 34.1 percent. The analysis results of the risk impact, i.e : 1) pest as much Rp. 793 146, 2) disease in amount of Rp. 734 049, 3) water quality of Rp. 1,075,684, and 4) cannibalism in amount of Rp. 956,926. Risk production management strategies for pest risk source, water quality, and cannibalism was by prevention. While the source of risk on disease was handled by manage the maintenance medium properly.

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
