Judul: Respon Fisiologis dan Tingkah Laku Domba Garut Jantan dengan Pakan dan Manajemen Pemberian Pakan Berbeda
Abstrak: Improving feeding and managament for sheep it is normally because of improving their performance. Thereby it can be effected to their physiological response and behaviour. This research aimed to compare physiological response and behaviour of garut rams with feed and different management feeding. This research used 16 garut rams (I0) with 2 factors and 4 replicates. First factors is type of feed R1 (40 % grass + 60% concentrate 1) dan R2 (40% mung bean sprout waste + 60% concentrate 2) and the second factors is management feeding in the morning (P) and management feeding in the afternoon (S). Physiological response were observed such as respiration, heart rate, and rectal temperatures. Behaviour were observed such as ingestive behaviour, licking and biteing other goods, resting, eliminasi, vokalisasi, and agonistic. Physiological response and behaviour data were analyzed by analysis of variance (ANOVA). The result shows that heart rate effected by feed. Sheep which is given feeding mung bean sprout waste have a higher value on heart rate (P<0.01). Rectal temperature efected by feed and management. Sheep which is given feeding mung bean sprout waste (P<0.01) and management feeding in the afternoon (P<0.05) have a higher value on rectal temperatures. Management feeding factors in morning of measuring ingestive behaviour have a higher value (P<0.05) but for resting behaviour, management feeding factors in the afternoon have a higher value (P<0.01). The grass have a higher value for eliminative in daylight periode (P<0.05). Both of factors were not significantly different (P>0.05) for measuring all of behaviour garut rams in the allnight periode.

Judul: Respon fisiologis domba garut yang dipelihara secara semi intensif dengan perlakuan pencukuran di peternakan PT Indocement
Abstrak: The study was conducted to identify physiological response of garut sheep in different treatments (shearing and not shearing) and sex (male and female) in semi intensive system. The experiment was carried out at the PT Indocement Farm in Citereup district of Bogor regency, West Java. Design of this experiment was completely randomized design factorial with factor A was shearing, and factor B was sex. The parameters observed included body temperature, heartbeat, respiration rate and blood profile. The result showed that shearing significantly (P<0,01) effect on body temperature in the morning. Body temperature of shearing sheep (37.97±0.28 0C) was lower than not shearing (38.47±0.310C). In the afternoon showed that shearing significant (P<0.05) effect on body temperature. Body temperature of shearing sheep (38.45±0.20 0C) was lower than not shearing (38.70±0.25 0C). Heartbeat of male (86.72±6.47 rate/min) was significant higher than female (81.24±4.12 rate/min) in the evening. Respiration rate of male (24.08±2.78 rate/min) was significantly lower than female (28.16±2.20 rate/min) in the morning. For shearing sheep was lower than not shearing in the morning and afternoon. In the evening both male and female sheep that are not shearing was not significant, but significant with respiration of male sheared and female sheared. Stress indicated in male sheep and proved from neutrophils/lymphocytes ratio (0.88±0.36). Conclusion of this experiment showed that shearing, sex and time effected to the physiological response.

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.
