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.

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

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
