Judul: Komposisi Karkas dan Non Karkas Kelinci Lokal Jantan Muda dengan Pemberian Pakan Limbah Tauge
Abstrak: Rabbits have potential to be developed as meat producer. Rabbit is palatable with almost every roughage, even market waste such as bean sprouts’ waste. Bean sprouts’ waste contains of 13.26% protein and 64.5% TDN. The aim of this research was to evaluate carcass and non carcass composition of male local rabbit age 12 weeks fed with bean sprouts’ waste. Measured variables were slaughter weight, empty body weight, hot carcass weight, cold carcass weight, commercial cuts, carcass composition weight, carcass and commercial cuts proportion, non carcass weight and percentage. This study used 12 male local rabbit fryer with average weight 747±104.543 g. The rabbits reared as long as 12 weeks and slaughtered at age of 6 months. This study used completely randomized design. There were 3 treatments that consisted of 100% of commercial feed (P0), 70% of commercial feed+30% of bean sprouts’ waste (P1), and 50% of commercial feed+50% of bean sprouts’ waste (P2). The data was analysed using ANCOVA with empty body weight and hot carcass weight as covariables. Results showed that the addition of bean sprouts’ waste causing non carcass weight, stomach and hindleg commercial cut weight and percentage were higher than without the addition of bean sprouts’ waste. Addition of bean sprouts’ waste had no effect on slaughter weight, empty body weight, and carcass weight. In conclusion, bean sprouts’ waste can be added fresh to rabbit feed up to 50% in substitute of commercial feed.

Judul: Komposisi Karkas dan Non Karkas Kelinci Lokal Jantan Muda dengan Pemberian Pakan Limbah Tauge
Abstrak: Kelinci memiliki potensi untuk dikembangkan sebagai salah satu ternak potong. Kelinci termasuk ternak yang menyukai segala jenis tumbuhan termasuk limbah pasar seperti limbah tauge. Limbah tauge mengandung 13.26% protein dan 64.5% TDN. Tujuan dari penelitian ini adalah untuk mengevaluasi komposisi karkas dan non karkas kelinci lokal jantan muda yang berumur 12 minggu dengan pemberian pakan mengandung limbah tauge. Peubah yang diamati adalah bobot potong, bobot tubuh kosong, bobot karkas panas dan dingin, bobot potongan komersial, bobot komposisi karkas, proporsi karkas dan potongan komersial, bobot dan persentase non karkas. Penelitian ini menggunakan 12 ekor kelinci lokal jantan dengan bobot badan awal sekitar 747 ± 104.543 g. Ternak dipelihara selama 12 minggu dan dipotong pada umur 6 bulan. Penelitian ini menggunakan rancangan acak lengkap (RAL). Terdapat tiga jenis perlakuan: 100% pakan komersil (P0), 70% pakan komersil+30% limbah tauge (P1), dan 50% pakan komersil+50% limbah tauge (P2). Data dianalisis dengan menggunakan ANCOVA dengan menggunakan bobot tubuh kosong dan karkas panas sebagai kovariabel. Penelitian ini menunjukkan dengan penambahan limbah tauge menyebabkan bobot non karkas, bobot dan persentase potongan komersial hindleg dan lambung lebih tinggi dibandingkan tanpa penambahan limbah tauge. Penambahan limbah tauge tidak mempengaruhi bobot potong, bobot tubuh kosong, dan bobot karkas. Sehingga dapat disimpulkan bahwa limbah tauge dapat diberikan dalam bentuk segar untuk penggemukan kelinci hingga 50% menggantikan pakan komersil

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.
