Judul: Produksi dan Morfometrik Ayam Persilangan Pelung Ras Pedaging dengan Sentul Kampung dan Resiprokalnya Umur 0-12 Minggu.
Abstrak: This research aimed to explore the production and morphometry of reciprocal crossed between pelung-broiler (PB) and sentul-kampung (SK) chickens age 0-12 weeks old. Commercial starter feed was offered at the age of 0- 3 weeks, 80% commercial starter feed + 20% rice hull at the age of 4 weeks and 60% commercial starter feed + 40% rice hull at the age of 5-12 weeks. Feed was ad libitum. The research used completly randomized design (RAL). Productive traits measured were body weight, growth rate, feed intake, feed conversion and mortality. Morphometry traits measured were length of shank, back, beak, width of breast and girth of breast. Body weight, growth rate, feed intake, feed conversion, width of breast, back, beak and volume of the body were not significant. Meanwhile, length of shank and girth of breast differed. PBSK and SKPB can be developed as meat type chickens.

Judul: Performa F1 antara Ayam Sentul X Kampung dan Ayam Pelung X Sentul pada Umur 0-12 Minggu
Abstrak: The experiment aimed to observe growth performance of 3 native chicken crossed. The materials used in this experiment were 22 day old chick (DOC) resulted of natural mating between male pelung and female sentul chicken (PS) and 113 DOC resulted of natural mating between male sentul and female kampung chicken (SK). Feeds were given during experiment divided into 3 phases that were BR-21E 100% for chicken between 0-3 weeks of age, rice bran 20% and BR-21E 80% for 4 week age, and grower feeds rice bran 40% and BR-21E 60% for chicken between 5-12 weeks. Variables which recorded weekly were body weight until 12 weeks of age, weight gain, feed consumption, feed conversion, and mortality. The t-test was used to compare data of performance between two sexes and between two cross system (PS and SK). The results showed that body weight at 12 weeks of crossbred (PS) male was significantly higher than SK (P<0.01) also female (P>0.05). Feed consumption and feed conversion were not significantly different (P>0.05). The mortality rate during the experiment were 4.54% for crossbred PS and 7.07% for SK. SK and PS can be applied to increase meat production.

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.
