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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
