Judul: Analisis Risiko dan Kebijakan Sumber Pasokan Ikan Hias Clown Loach pada PT. Qian Hu Joe Aquatic Indonesia
Abstrak: Clown loach is a species of fish that most preferred by customers but its availability is still limited. In order to meet the request, the company should work with various suppliers. There are two kinds of suppliers, external suppliers and internal suppliers (companies produce their own fish). The best supplier policy is set by company to maintain the flow of inputs and outputs in order to remain efficient. The aim of the study is to identify the characteristics of the Clown Loach’s supplier and analyze sources of supply that is beneficial to the company. Method of data analysis using decision diagram for two kinds of policy scenarios. Meanwhile, the calculations using Microsoft Excel. The results of supplier’s policy analysis when uncertain policy is a company gains a higher profit if relying on external suppliers as the major supplier. The cost is Rp 842.465.792 with fish mortality risk of Rp 10.273.973 and profit gains Rp 280.993.163. External suppliers ensure that they offer fish with better quality, ready to be shipped, and the company does not need to pay operational charge.

Judul: Risiko Produksi Ikan Hias pada PT Qian Hu Joe Aquatic Indonesia di Kabupaten Bogor, Provinsi Jawa Barat
Abstrak: Ikan hias merupakan komoditas perikanan yang cukup prospektif untuk dikembangkan karena memiliki nilai ekonomis yang tinggi. Dalam pelaksanaan usaha ikan hias tidak terlepas dari adanya risiko usaha. Penelitian ini dilakukan untuk mengidentifikasi sumber-sumber risiko produksi pembesaran ikan hias yang dihadapi PT. Qian Hu Joe Aquatic Indonesia, menganalisis hubungan antara diversifikasi usaha dengan upaya meminimalkan risiko, serta memberikan alternatif strategi yang memungkinkan dalam penanganan risiko produksi yang dihadapi perusahaan. Metode analisis yang digunakan dalam penelitian ini adalah analisis varian, standar deviasi, koefisien variasi, dan expected return. Penelitian ini memberikan informasi bahwa sumber-sumber risiko produksi yang dihadapi perusahaan diantaranya kondisi iklim dan cuaca, serangan penyakit, dan kesalahan tenaga kerja. Hasil analisis risiko pada komoditas tunggal diperoleh risiko yang paling tinggi adalah ikan clown loach, nilai risiko yang paling rendah adalah ikan black ghost. Hasil analisis risiko diversifikasi diperoleh nilai risiko paling rendah pada kombinasi ikan black ghost dan silver arowana. Alternatif strategi yang dapat dilakukan perusahaan dalam mengurangi risiko produksi adalah melakukan diversifikasi produksi dan kemitraan.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
