Judul: Tingkah Laku Domba Garut Jantan Muda dengan Pemeliharaan Intensif yang Diberi Ransum Limbah Tauge pada Waktu Pemberian yang Berbeda
Abstrak: Research aimed to evaluate the effect of bean sprout waste as grass substitution and feeding time toward the ingestive, agonistic, and resting behaviour of the lamb. About 16 heads of lamb were maintained for 3 months with 2 treatments factors (feed and feeding time). The method was focal sampling and the datas were analysed using ANOVA. The result showed that there was no interaction between feed and feeding time toward the ingestive, agonistic, and resting behaviour. Feeding time gave significant effect (P<0.05) to the ingestive frequencies and agonistic duration. Morning feeding time gave higher consumption than afternoon feeding time meanwhile, afternoon feeding time gave higher effect for agonistic behaviour than morning feeding time.

Judul: Tingkah Laku Harian dan Pola Makan pada Domba Garut dengan Pemberian Pellet yang Mengandung Limbah Tauge dan Legum Indigofera sp.
Abstrak: Changes in the feed management can contribute to the change of behaviour that will impact on the productivity of livestock. The aim of this research was to study sheep behaviour as a result of giving bean sprouts waste pellet and Indigofera sp. pellet in the ration. This research used 6 garut lambs of 3 month old. There were two types experimental rations: (1) 30% of Indigofera sp.+70% concentrate and (2) 30% of bean sprout waste+70% concentrate. Parameter measured were sheep daily behaviour and eating behaviour. The data were recorded by a one zero sampling method and analyzed by Chi-square test. Data temperature and humidity obtained during the research were analyzed by Analysis of Varian (ANOVA). The result of temperature in the noon was significant higher than in the morning and afternoon, humidity in the morning was significant higher than in the noon and afternoon. Results showed that the daily behaviour exhibited by sheep with two types of ration (bean sprout waste and Indigofera sp.) were not significant. The activity of feed checking behaviour was significant, where the provision of Indigofera sp. pellet had greater frequency than bean sprout waste pellet, but did not cause stress to livestock. It is concluded that the two type of rations can be recommended to use in local sheep farm

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.
