Judul: Performa Kelinci Potong Jantan Lokal Peranakan New Zealand White Yang Diberi Pakan Silase Atau Pelet Ransum Komplit
Abstrak: Complete ration silage has never been used in rabbits farm industry. Therefore, it is necessary to evaluate the quality in an attempt to reach feed security. The aim of this study was to compare and analize the effect of feeding complete ration silage on the performance of rabbits. This research used two diet treatments with six replications, each of which consisted of 6 rabbits with body weight of 1375.28 g ± 204.52. The treatments were complete ration pellet (R1) and complete ration silage (R2). The data obtained were analyzed using t-test. The result showed that the treatments significantly (P<0.01) affected feed consumption and body weight. The average feed consumption of New Zealand White was 824.49 ± 51.04 for complete ration pellet (R1) and 645.74 ± 19.16 for complete ration silage (R2). The average body weight for complete ration pellet (R1) was 1906.45±135.80 and it was 1663.15 ±110.07 for complete ration silage (R2). However, the treatments did not significantly influence daily weight gain, feed efficiency, carcass percentage and fat thighs. It can be concluded that complete ration silage has similar quality to complete ration pellet in terms of affecting performance of rabbits.

Judul: Performa Induk Kelinci Peranakan New Zealand White dengan Pemberian Pellet dan Silase Ransum Komplit Berbasis Pakan Lokal
Abstrak: Ketersediaan pakan merupakan salah satu faktor penting dalam usaha pemeliharaan ternak disamping faktor pemilihan bibit dan tata laksana pemeliharaan yang baik. Agar kelinci dapat berproduksi tinggi, maka perlu dipelihara secara intensif dengan pemberian pakan yang memenuhi syarat, baik secara kualitas maupun kuantitas. Pakan kelinci pada umumnya adalah hijauan atau pellet. Permasalahan pada penggunaan rumput adalah kurangnya asupan nutrien sehingga kelinci tidak dapat berproduksi dengan maksimal. Kendala dari penggunaan pellet adalah proses pembuatannya membutuhkan alat-alat yang relatif mahal sehingga akan memberatkan peternak. Oleh karena itu dibutuhkan alternatif lain agar dapat mengurangi biaya pembuatan pakan kelinci tersebut. Silase ransum komplit adalah alternatif pengolahan pakan yang cukup baik. Silase ransum komplit dapat memenuhi kebutuhan gizi ternak dan memiliki sifat organoleptik (bau harum, asam) sehingga lebih disukai ternak (palatabel). Penelitian ini bertujuan untuk membandingkan performa reproduksi induk kelinci peranakan New Zealand White yang diberi silase ransum komplit dan pellet ransum komplit meliputi persentase kebuntingan, lama kebuntingan, jumlah anak per kelahiran (litter size), jumlah bobot anak per kelahiran (litter weight) dan bobot lahir individu anak. Ternak yang digunakan sebanyak 12 ekor kelinci betina peranakan New Zealand White umur 6 bulan dengan rataan bobot hidup 1696,33±109,92 g. Dalam penelitian ini digunakan rancangan acak lengkap (RAL) dengan dua perlakuan dan 6 ulangan. Perlakuan pertama adalah pellet ransum komplit (R1) dan yang lain adalah silase ransum komplit (R2). Data konsumsi ransum (BK, PK, SK, LK, BETN), pertambahan bobot badan dan efisiensi ransum dianalisis menggunakan sidik ragam (ANOVA) dan apabila terjadi perbedaan yang nyata dilakukan analisis uji t, sedangkan data persentase kebuntingan, lama kebuntingan, bobot lahir, jumlah anak per kelahiran dan jumlah bobot anak per kelahiran dianalisis secara diskriptif.

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.
