Judul: Persentase karkas, lemak  abdominal dan organ dalam ayam pedaging yang diberi ransum mengandung limbah restoran hotel sahid sebagai substitusi dedak padi
Abstrak: This research'was conducted to observe the effect of sahid hotel's restaurant waste in replacing rice bran in the diets on the percentage of carcass, abdominal fat and viscera. The research used 120 chicks which were reared for five weeks. At the end of the experiment, 24 chickens were slaughterd to measure the parameters observed. The experiment used Compeletely Randomized Design with 3 treatments and 4 replications. The treatment diets were : PI (I 3% rice bran without sahid hotel's restaurant waste), P2 (6.2% rice bran and 6.2% sahid hotel's restaurant waste) P3 (12% sahid hotel's restaurant waste without rice bran). The data were analyzed using ANOVA (Analysis of Variance) and the significant differences were further tested by contrast orthogonal test. The results showed that using 6.2% sahid hotel's restaurant waste (P2) significantly (P<0.05) increased the percentage of carcass and highly significantly (P<0.01) decreased the length of intestine and caeca. The conclusion of this research was that usage 6.2% sahid hotel's restaurant waste in the diets increased the percentage of carcass without disturb the digestive organs as well as the percentase of abdominal fat. Key worh: rice bran, sahid hotel's restaurant waste,.carcass, abdominal fat, viscera, broilers.

Judul: Kinerja produksi ayam broiler yang diberi limbah restoran Hotel Sahid sebagai pengganti dedak padi
Abstrak: The aim of this experiment was to study the substitution of rice bran with restaurant waste in the broiler diets. One hundred and twenty day old chicks (DOCs) strain Cobb were used. They were divided into Completely Randomized Design consisted of 3 treatments and 4 replicates, each consisted of 10 broilers. They were kept in animal house with litter system. The treatments were:1) the diet contained 13% rice bran, without restaurant waste (P1), 2) the diet contained 6.2% rice bran and 6.2% restaurant waste (P2), 3) the diet without rice bran, but contained 12% restaurant waste (P3). The results showed that the treatments significantly (P<0.01) affected feed intake, body weight gain, final body weight, and water intake but did not affect to feed conversion. It was concluded that the restaurant waste could be used until the level of 12% in the diet, but the best result obtained at the level of 6.2% of restaurant waste.

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.
