Judul: Studi bobot badan dan ukuran-ukuran tubuh domba ekor gemuk di pulau Madura dan rote
Abstrak: The body measurements can be used to estimate body weight. It is more practical to used it in field and it has high accuracy without weight processing. Therefore, the aims of this study was to estimate body weight based on body measurements. In addition, this study were aimed to estimate body weight differences at two different locations and to determinate the best equation which can be used to estimate body weight of fat-tailed sheep at Madura Island and Rote Island.

Judul: Estimation of Life Weight of Madura Fat Tail Sheep Based on Morfometric Measurements
Abstrak: Ukuran tubuh domba dapat digunakan untuk menaksir bobot hidup dan memberi gambaran bentuk tubuh sebagai ciri khas suatu bangsa tertentu. Penelitian ini bertujuan untuk menduga bobot hidup domba berdasarkan ukuran morfometrik tubuh panjang badan, lingkar dada, dan dalam dada domba di Pulau Madura pada umur dan jenis kelamin berbeda. Materi yang digunakan data sekunder dari pengukuran morfometrik tubuh domba ekor gemuk (DEG) madura dengan jumlah 86 ekor domba dan dibedakan menjadi empat kelompok berbeda umur dan jenis kelamin yaitu betina I0, betina I2, jantan I0, jantan I2. Analisis data yang digunakan adalah analisis regresi linier ganda dengan persamaan Y = β0+ β1X1+ β2X2+...+ βnXn. Hasil penelitian menunjukkan bahwa ukuran tubuh panjang badan, lingkar dada, dan dalam dada DEG dapat digunakan untuk menaksir bobot hidup dengan pengukuran morfometrik memiliki tingkat pengaruh yang sangat signifikan dengan nilai koefisien determinasi dan korelasi yang berpengaruh sangat kuat

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.
