Abstrak: Javan porcupine (Hystrix javanica) is one of the Indonesian endangered species due to hunting by local communities for commercial purpose. One of alternative methods to preserve the species is domestication through ex-situ breeding. The objective of this study was to examine the influence of koi fish pellet added to the ration on Javan porcupine carcass characteristics. This experiment used eight Javan porcupines fattened for eight weeks. The result showed that weight and percentage of muscle was significantly different (P<0,05). This research also had found M. Cutaneus trunci on the anatomical structure under skin layers of Javan porcupine. The effect of the addition of koi fish pellet into feed gave a significant effect on the meat weight of Javan porcupine but did not give a significant effect on commercial pieces of the carcass

Abstrak: The study was aimed to analyze the weight of carcass and non carcass components in Javan porcupine. Four samples of Javan porcupines consisted of three males and one female were used in this study. Data collected were slaughter weight, weight and percentage of carcass and non-carcass components. The acquired data were descriptively analyzed. The result show that the average of carcass and non-carcass weight were 4.627,62 gram and 2.491,22 gram while the average of carcass and non-carcass percentage were 64,98 % and 35,02 % respectively. The biggest proportion of non-carcass components were head (6,46 %), spine (5,93 %), stomach (5,72 %), and blood (2,98 %) while the smallest proportion of non-carcass components were esophagus (0,13 %), pancreas (0,13 %), and spleen (0,12 %). Based on this study, the average weight of carcass in Javan porcupine was relatively high due to the thickness of porcupine meat coupled with skin and tail.

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.
