Judul: Korelasi Tingkah Laku Makan dengan Performa Kambing Marica Jantan yang Diberi Pakan Berbeda
Abstrak: Kambing marica sebagai plasma nutfah endemik di Indonesia memiliki kemampuan daya adaptasi yang cukup baik. Kambing marica yang ada di Sulawesi Selatan mengalami penurunan populasi disebabkan karena manajemen pakan yang kurang baik sehingga berdampak pada penurunan performa. Penelitian ini bertujuan untuk mengkaji tingkah laku makan dari kambing marica yang diberi pakan berbeda serta korelasinya terhadap pertambahan bobot badan harian dan tingkat konsumsi. Penelitian ini menggunakan delapan ekor kambing marica jantan yang dipelihara pada kandang individu selama delapan minggu. Perlakuan pakan yang diberikan selama penelitian adalah pakan komplit berupa konsentrat dan pakan hijauan (Indigofera sp. dan Pennisetum purpureum). Berdasarkan hasil uji korelasi Pearson menunjukkan bahwa terdapat hubungan signifikan antara parameter tingkah laku makan dengan pertambahan bobot badan harian dan tingkat konsumsi (P<0,05). Peubah tersebut diantaranya yaitu tingkah laku deglutisi terhadap pertambahan bobot badan harian kambing marica yang diberi pakan komplit, tingkah laku deglutisi dan lama ruminasi terhadap konsumsi dari kambing marica yang diberi pakan hijauan dan periode ruminasi terhadap konsumsi dari kambing marica yang diberi pakan hijauan. Nilai korelasi positif menunjukkan adanya hubungan positif dan signifikan antara tingkah laku deglutisi dan lama ruminasi terhadap performa dari kambing marica. Nilai korelasi yang bernilai negatif menunjukkan terdapat hubungan linier negatif antara periode ruminasi terhadap tingkat konsumsi kambing marica., Marica goat is an endemic germplasm in Indonesia, known for its good abilities and adaptability. The population of Marica goats in South Sulawesi has begun to decline and is at risk of extinction due to poor feed management that affect the performance. The objective of this study is to investigate the feeding behavior of Marica goats under different feeding regimes and to determine the correlation with daily body weight gain and consumption levels. The Marica goat used in this research were eight head, housed in individual cages for eight weeks. The feed given was a complete feed consisting of concentrate and green fodder (Indigofera sp. and Pennisetum purpureum). The result of Pearson correlation test showed that there were parameters of feeding behavior that had a significant relationship with daily body weight gain and level of consumption (P<0.05). These parameters included gorging behavior on daily body weight gain of Marica goats fed complete diet, gorging behavior and rumination time on consumption of Marica goats fed forages, and rumination period on the consumption of Marica goats fed complete diets. A positive correlation value indicates that there is a positive and significant relationship with gorging behavior and rumination time on performance of Marica goats. On the other hand, a negative linear relationship with rumination period on the consumption of Marica goats.

Judul: Nilai mutu daging dan perdagingan kambing kacang dan domba lokal dengan jenis kelamin yang berbeda yang dipelihara secara intensif (dikandangkan)
Abstrak: Livestock as an agriculture sub sector plays an importance role for Indonesian development Large number of population, estimated about over- than 210 million .people, surely have a bigger demand on animal protein. Local goat and Priangan sheep have contributed significantly on meat protein supply. However, the comparative information about meat quality differences of these animals is limited. This study was aimed to compare the carcass and meat characteristic of sheep and goat The observed variables were slaughter weight, weight and percentage of carcass, weight and percentage of pelvic and kidney, large rib eye, weight and percentage of meat; weight and percentage of fat; weight and percentage of bone and characteristic of meat. This result showed that s&ies significanly effect (F<0,05) to weight and percentage of meat, weight and percentage of fat, basic cut distribution carcass on breast and fore shankmeat dismbution on breast, flank and fore shank, fat distribution on shoulder and rack, b o ~d~isetr ibution on shoulder and fore shank: pH. . Ses has significant effect (P<0,05) to weight and percentage of fat on the pelvic and kidnet, ureight and percentage of fat, weight and percentage of bone, basic cut distribution carcass on shoulder, bone dismbution on leg, loin and shoulder, fat distribution on loin, breast, and flank, tenderness. Interaction has significant effect (P<O,Oj) to distribution carcass on leg; distribution bone on breast, cooking lose and water holding capacity (LVHC).

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.
