of Carcass and Organs of Broiler Chickens with Feed Containing Garlic Treatment.
Abstrak: Pemanfaatan ayam ras pedaging menyimpan resiko bagi konsumen, karena penggunaan berbagai jenis Antibiotic Growth Promoter (AGP). Studi pada bawang putih sebagai alternatif dari promotor pertumbuhan produksi ternak dilakukan dan efek menguntungkan pada pertumbuhan dan daya cerna. Penelitian ini bertujuan mengkaji persentase bobot potongan komersial dan organ ayam broiler yang diberi pakan dengan penambahan bawang putih sebanyak 3%. Rancangan percobaan penelitian ini menggunakan RAL dengan 4 perlakuan yaitu, pakan kontrol (P0), bawang putih segar P1, bawang putih kering P2 dan bawang hitam P3 dengan 5 ulangan. Pengambilan sampel dilakukan dengan memotong bagian karkas menjadi 4 bagian yaitu, dada, paha, sayap, dan punggung lalu diambil organ dalam meliputi hati, ampela, jantung, limpa, dan bursa fabricius. Data yang diperoleh dianalisis secara statistik dengan menggunakan sidik ragam (analysis of variance/ ANOVA) menggunakan aplikasi SPSS. Pemberian olahan bawang putih sebesar 3% sebagai subtitusi AGP tidak memberikan pengaruh yang nyata (P>0,05) terhadap persentase bobot potongan komersial dan persentase bobot organ ayam broiler, perlu penelitian lanjutan menggunakan dosis penambahan olahan bawang putih yang berbeda., The use of broiler chickens poses a risk to consumers, due to the use of various types of Antibiotic Growth Promoter (AGP). Studies on garlic as an alternative of a growth promoter in livestock production were carried out and its beneficial effects on growth and digestibility were carried out. This study aims to determine the percentage of commercial slaughter weight and organs of broiler chickens fed with the addition 3% of garlic. The experimental design of this study used RAL with 4 treatments namely, control feed (P0), fresh garlic P1, dry garlic P2 and black garlic P3 with 5 replications. Sampling was carried out by cutting the carcass into 4 parts, chest, thigh, wings and back and then taking the internal organs including liver, gizzard, heart, spleen, and bursa fabricius. The data obtained was analyzed statistically using analysis of variance (ANOVA) using the SPSS application. Provision of processed 3% garlic as a substitute for AGP did not have a significant effect (P> 0,05) on the percentage of commercial slaughter weight and the percentage of broiler organ weight, further research is needed using different added doses of processed garlic

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.
