Judul: Kecernaan Nutrien dan Retensi Nitrogen Ransum Mengandung Limbah Tauge dengan Waktu Pemberian Berbeda pada Domba Garut
Abstrak: Mung bean sprouts waste as alternative feed ingredients have good nutritional quality as livestock feed. Research aimed to eva luate the digestibility of dry matter, organic matter, crude protein, crude fat, crude fiber, extract material without nitrogen and nitrogen retention ration with different feeding time management (morning and evening) of Garut lamb. About 12 heads of Garut sheep with the average body weight 15.06±2.41 kg were analyzed in 2x2 factorial randomized complete block design. The first factor was different feed fonnu!a consist of RI (consent rate 60% + grass 40%) and 40%) and R2 (consent rate 60% + mung bean sprouts waste 40%). The second factor was different feeding time consist of P (morning) and S (evening). The result of statistic analysis showed there was no interaction both of treatment in consumption nutrient, digestibility nutrient, nitrogen retention . The type of feed had significant effect (P<O.OS) in DM, Ash, CP, CF, EE, NFE consumption (g kg ., BBo.75). Different feed fonnula treatment had significant effect (P<0.05) in DM, CP, CF for digestibility nutrient, so that different feeding time and the interaction with different feed formula had not significant effect (P>0.05). The value nitrogen retention , nitogen consumption, feces nitrogen and NBP showed that type of feed had significant effect (P<0.05) but feeding time consist of P (morning) and S (evening) bad significant effect (P<0.05) in nitrogen feces and EPN (g kg -, BBo.75).

Judul: Performa Domba Garut Jantan yang Diberi Pakan Limbah Tauge sebagai Pengganti Rumput Lapang pada Waktu Pemberian yang Berbeda
Abstrak: Research aimed to evaluate the effect of mung bean sprout waste as grass subtitution and different feeding time management (morning and evening) through the performance of Garut lamb in intensive system. About 16 heads of Garut lamb with the average body weight 15.06 ± 2.41 kg were analyzed in 2x2 factorial randomized complete block design. The first factor was different feed formula consist of R1 (consentrate 60% + grass 40%) and R2 (concentrate 40% + mung bean sprout waste 40%). The second factor was different feeding time consist of P (morning) and S (evening). The result of statistic analysis showed that R2 had significant effect (P<0.01) in DMI, CP, and TDN consumption. Different feed formula had significant effect (P<0.01) in ADG, so that the different feeding time and the interaction with different feed formula also had significant effect in ADG (P<0.05). Feed efficiency of R2 was higher (P<0.05) than R1. Mung bean sprout waste had better palatability than grass so that it enhanced the performance of Garut lamb with better feed efficiency.

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.
