Judul: Literature Review: Factors of Feeding and Slaughter Age on Weight and Percentage of Chicken Broiler Carcasses
Abstrak: Ayam broiler memiliki keunggulan dari segi pertumbuhannya yang sangat cepat dengan bobot badan yang tinggi dalam rentan waktu pemeliharaan yang pendek, konversi pakan yang rendah, dan siap dipotong pada usia muda serta menghasilkan kualitas daging berserat lunak. Untuk mendapatkan produksi yang optimal, ayam broiler harus di beri pakan yang tepat dan dipotong pada umur yang tepat. Tugas akhir ini dilakukan dengan menggunakan metode studi pustaka. Studi pustaka ini dilakukan dengan tujuan untuk mengkaji pengaruh faktor pemberian pakan dan umur pemotongan terhadap bobot dan persentase karkas pada ayam broiler. Literatur yang digunakan bersumber dari jurnal nasional terakreditasi. Hasil studi menunjukkan pemberian berbagai jenis pakan yang berbeda seperti pemberian bahan pakan, pakan komersil, suplemen, dan feed additive dapat memberi pengaruh yang berbeda terhadap bobot dan persentase karkas ayam broiler. Ayam broiler dapat dipotong pada umur kisaran 5-6 minggu agar bobot dan persentase karkas ayam broiler yang dihasilkan optimal., Broiler chickens have the advantage of their very fast growth, high body weight, and are prone to short maintenance times, low feed conversion, and are ready to be slaughtered at a young age and produce quality soft fibrous meat. To get optimal production, broilers must be fed the right kind and cut at the right age. This final project is done using the literature study method. This literature study was conducted to asses the feeding factor and slaughtering age on carcass weight and percentage in broiler chickens. The literature used is an accredited national journal. The study results show, providing various types of feed likes feed ingredients, commercial feeds, supplement, and feed additives can give a different effect on the live weight and percentage of broiler carcasses, some of them give a good effect, bad effect, and no effect. Broiler chicken should be slaughtered at the age of 5-6 weeks so that the weight and percentage of broiler chicken carcass are optimal.

Judul: The Effect of Feed Withdrawal Time Lengths  Pre Transportation towards Glucose Levels in Blood, Life Weight, and Carcass of  Broiler Chicken
Abstrak: Ayam broiler harus dipuasakan sebelum diangkut. Pemuasaan pakan diperlukan untuk mengosongkan sistem pencernaan pada karkas sebelum disembelih. Penelitian dilakukan untuk menganalisis penyusutan bobot badan ayam broiler dari pengaruh perbedaan lama pemuasaan sebelum transportasi. Penelitian ini menggunakan 126 ekor ayam broiler dengan bobot rata-rata 1,4 kg pada umur 28 hari. Penelitian menggunakan Rancangan Acak Lengkap yang terdiri dari tiga perlakuan dan tiga ulangan. Parameter yang diukur yaitu penyusutan bobot badan, kadar glukosa darah, dan persentase karkas. Penelitian ini menggunakan analisis deskriptif. Hasil penelitian menunjukkan bahwa pemuasaan memiliki pengaruh terhadap penyusutan bobot badan, kadar glukosa darah, dan persentase karkas. Disimpulkan bahwa pemuasaan selama empat jam memiliki pengaruh yang baik daripada tanpa pemuasaan dan pemuasaan selama delapan jam., Broiler Chickens have to fasten from the feed before transportation. Feed withdrawal is needed to empty the digestive system to avoid carcass contamination during slaughtering. This study analyzes the weight loss, blood glucose, and carcass percentage of broiler chickens as the results of different fasting times before transportation. The study used 126 broiler chickens with an average weight of 1,4 kg at 28 days of age. A Completely Randomized Design is applied. The experimental design consists of three treatments consist of no fasting (P1), four hours fasting (P2), and eight hours fasting (P3) with three repetitions. One repetition consists of 14 broilers. The parameter observed was the weight loss, glucose levels in the blood, and carcass percentage. Data are analyzed descriptively. Results showed that fasting time affected body weight loss, blood glucose levels, and carcass percentage. Four hours fasting time before transportation showed better results than no fasting time and eight hours fasting time.

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.
