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: Performa Domba Garut dengan Pemberian Pakan Limbah Tauge dan Kangkung Kering Sebagai Hijauan Pengganti Rumput
Abstrak: The improvement of feed quality and raising management can increase the sheep performance. Nowadays, the availability of feed such as good quality grass is relatively expensive; therefore, there should be an alternative feed in place of grass. This research aimed to test the performance of male Garut sheep aged less than one year which was fed by bean sprout waste and dried kangkung as alternative feed. The raising time was two months. The feed treatment consisted of P0 (50% grass and 50% concentrate), (50% bean sprout waste and 50% concentrate), and (50% dried and 50% concentrate). The parameters observed were Daily Weight Gain, feed consumption, feed efficiency, and palatability. This study used complete by random design using feed factors. The data analysis used was ANOVA test, and if significantly influenced, Duncan test would be carried out. The research result showed that different kinds of feed did not have a significant effect on Daily Weight Gain and feed efficiency. However, it had a significant effect on feed consumption and palatability. Based on this research, it can be concluded that in general alternative feeds in form of bean sprout waste and dried kangkung can replace grass since the nutrition content is almost the same and generates similar Daily Weight Gain.

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.
