Judul: Analisis Risiko Produksi Pembenihan Lele Sangkuriang Pada CV Dejee Fish Kabupaten Sukabumi
Abstrak: Sangkuriang catfish (Clarias sp) which lives in freshwater habitats, has a good economic value. One of the companies that work’s on the cultivation of sangkuriang catfish is CV Dejee Fish, located at Cibaraja’s Fish Market, Cisaat, Sukabumi. Unfortunately, this business is highly related to several risks such as production risk where CV Dejee Fish production fluctuates in a high manner. The object of this study is to identify the sources of production risk, the chances, the impact, and some alternative strategy to handle the risk. The sources of production risk are identified as fungi, water quality, fish feed, and harvesting technic. Furthermore, in order to understand how big the chances and impact of the risk are, Z-score and VaR analysis tool is used. Results from the research shows that on the per period per hetchery, the risk probability from fungi is 40 percent, water quality 44 percent, feeds 5 percent, and harvesting technic 4 percent. The impact of the risk from fungi cost is Rp 5 795, water quality Rp 4 937, feeds Rp 3 388 and harvesting technic Rp 3 736.

Judul: Analisis Risiko Produksi Pembenihan Ikan Lele Sangkuriang di Sangkuti Farm Kecamatan Megamendung Kabupaten Bogor
Abstrak: Lele Sangkuriang (Clarias sp) merupakan ikan air tawar yang memiliki nilai ekonomis yang cukup baik dan memiliki peluang untuk dikembangkan. Salah satu perusahaan yang membudidayakan jenis ikan lele sangkuriang adalah Sangkuti Farm Kecamatan Megamendung Kabupaten Bogor. Dalam menjalankan usahanya tersebut tidak terlepas dari adanya risiko produksi yang terlihat pada fluktuasi produksi yang dialami oleh Sangkuti Farm. Tujuan penelitian ini adalah mengidentifikasi sumber risiko produksi, menganalisis probabilitas dan dampak risiko, serta merumuskan alternatif strategi untuk penanganan risiko. Data diperoleh dari observasi dan wawancara dengan pemilik dan petugas kolam. Nilai probabilitas dan dampak diukur dengan menggunakan metode Z-Score dan Value at Risk (VaR). Sumber risiko teridentifikasi yaitu berasal dari faktor kualitas induk, penyakit, kanibalisme, dan human error. Dampak kerugian yang ditimbulkan masing-masing sumber risiko secara berurutan yaitu sebesar Rp 16 453 149, Rp 8 460 409, Rp 13 458 216, dan Rp 1 261 179 pada taraf nyata 5 persen. Nilai-nilai tersebut menunjukkan status risiko yang akan memengaruhi prioritas penanganannya. Penanganan risiko dilakukan dengan menerapkan strategi mitigasi.

Judul: Sintesis dan Pencirian Natrium Titanat (Na2Ti2O4(OH)2) Berbahan Dasar Titanium Dioksida
Abstrak: TiO2 can be utilized as basic material for synthesis of sodium titanate (Na2Ti2O4(OH)2). This research was purposed to synthesize and characterize sodium titanate from TiO2 rutile powder as a basic material. Sodium titanate was synthesized by hydrothermal process at temperature 130 °C by mixing TiO2 rutile powder with 5 M and 10 M NaOH solution, then each was calcinated at temperature 700 °C. The energy dispersive X-ray analysis showed that sodium titanate has been successfully synthesized. This result was also supported by functional group analysis with Fourier transform infrared (FTIR) spectrofotometer showing the existence of Ti-O-Na vibration band at 989.42 cm-1. The formation of sodium titanate was depend on the reaction condition such as temperature, reaction time, and NaOH concentration. Scanning electron microscope image indicated that sodium titanate synthesized at 130 °C in 20 hours reaction time with 10 M NaOH had crystal size of 99.37 nm.
