Judul: Body Size and shape of Etawah Grade Does with I3 Tooth Condition in Different Farms
Abstrak: Penampilan seekor ternak adalah hasil dari proses pertumbuhan dan adaptasi yang berlangsung dalam kehidupan ternak. Kambing PE yang banyak tersebar di beberapa wilayah Indonesia dengan lingkungan dan manajemen yang berbeda memiliki karakteristik morfometrik yang berbeda. Penelitian ini bertujuan untuk menentukan karakteristik morfometrik beserta penciri berdasarkan ukuran dan bentuk tubuh kambing PE betina dewasa di BBPTU-HPT Baturraden, Jawa Tengah dan BPTU-HPT Pelaihari, Kalimantan Selatan. Ukuran dan bentuk tubuh kambing PE betina dewasa memberikan sumbangan pada data dasar morfometrik tubuh yang diperlukan dalam penentuan karakteristik informasi dasar kambing. Data sekunder digunakan dalam penelitian ini. Jumlah kambing PE yang digunakan dalam penelitian ini adalah 60 ekor. 30 ekor di Peternakan Baturraden dan 30 ekor di Peternakan Pelaihari betina dewasa dengan kondisi gigi seri I3. Variabel yang diukur adalah tinggi pundak (X1), tinggi pinggul (X2), panjang badan (X3), lebar dada (X4), dalam dada (X5), lebar pinggul (X6), panjang kelangkang (X7), lingkar dada (X8) dan lingkar kanon (X9). Analisis data menggunakan Statistik Deskriptif, T2-Hotelling, dan analisis Komponen Utama. Lingkar dada (X8) ditetapkan sebagai penciri ukuran tubuh dikedua peternakan. Tinggi pundak (X1) ditetapkan sebagai penciri bentuk tubuh dikedua peternakan. Diagram kerumunan data tubuh individu kambing PE membentuk kerumunan sendiri., The appearance of livestock is the result of growth process and adaptation in the life of livestock. Etawah-grade goat that are widely distributed in several regions of Indonesia have different morphometric characteristics as they have different environment and management. The purpose of this research was to determine the genetic information of morphometric characteristics and characteristics of the etawah-grade does body size and shape in BBPTU-HPT Baturraden, Central Java and BPTU-HPT Pelaihari, South Kalimantan. The body size and shape of etawah-grade does contributed to the basic body morphometric which was required in the determination of basic characteristic information of the etawaha-grade goat. Secondary data were used in this study. The amount of etawah-grade does used in this study were 60 heads, 30 heads at Baturraden Farm and 30 heads at Pelaihari Farm, with I3 tooth condition. The variables measured were shoulder height (X1), hip height (X2), body length (X3), chest width (X4), depth chest (X5), hip width (X6), rump length (X7), chest circumference (X8) and the canon circumference (X9). Data analyzed by Descriptive Statistics, T2-Hotelling, and Principal Component Analysis. Chest circumference (X8) was defined as main body size characteristic in both farms. Hip height (X1) was defined as main body shape characteristic in both farms. The data group of the individual etawah-grade does body were forming different groups.

Judul: Peubah Pembeda Ukuran Tubuh Kambing Peranakan Etawah (PE) Induk Betina di antara Peternakan yang Berbeda
Abstrak: Kambing Peranakan Etawah (PE) merupakan hasil grading-up antara kambing etawah dan kambing kacang yang mewariskan sifat-sifat tetuanya. Perubahan morfologi pada kambing PE dapat terjadi akibat perbedaan adaptasi di kondisi ekologi yang berbeda-beda. Penelitian ini bertujuan untuk mengetahui variabel pembeda ukuran permukaan tubuh kambing PE betina dewasa yang sudah laktasi (umur 3 tahun atau kondisi gigi I3) antara BBPTU-HPT Baturraden dan BPTU-HPT Pelaihari di Kalimantan Selatan. Pengukuran permukaan tubuh linear kambing PE meliputi tinggi pundak (X1), tinggi pinggul (X2), panjang badan (X3), lebar dada (X4), dalam dada (X5), lebar pinggul (X6), panjang pinggul (X7), lingkar dada (X8), dan lingkar kanon (X9). Data dianalisis dengan statistik deskriptif, T2 Hotelling, diskriminan Fisher, dan penggolongan Ward-Anderson. Peubah pembeda ukuran permukaan tubuh linear antara kambing PE betina peternakan Baturraden dan Pelaihari ditemukan sebanyak 6 buah, yaitu tinggi pundak (X1), lebar dada (X4), dalam dada (X5), panjang pinggul (X7), lingkar dada (X8), dan lingkar kanon (X9). Penggolongan Wald-Anderson menunjukkan bahwa kelompok kambing PE di peternakan Baturraden dan Pelaihari tidak memiliki kemimripan ukuran tubuh sehingga seluruh kelompok kambing PE di masing-masing peternakan dapat dipertahankan., Etawah-grade Goat is the result of grading up between etawah goat and kacang goat that has the inheritance of their parents' trait. Morphological changes in etawah-grade goat can occur due to differences in adaptation in different ecological conditions. The purpose of this research was to determine the discriminator variables of body size measurements in BBPTU-HPT Baturraden and BPTU-HPT Pelaihari with a total of 30 heads of does in each farm. Body size measurements was performed on 3 years old Etawah-grade does which consisted of withers height (X1), hip height (X2), body length (X3), chest width (X4), chest depth (X5), hip-width (X6), hip-length (X7), chest girth (X8), and cannon circumference (X9). Data were analyzed by descriptive statistics, T2-Hotelling, Fisher discriminant, and Wald-Anderson classification. Six discriminator variables were found in Baturraden and Pelaihari, consisted of withers height (X1), chest width (X4), chest depth (X5), hip-length (X7), chest girth (X8), and cannon circumference (X9). The classification of Wald-Anderson showed that Etawahgrade does of Baturraden and Pelaihari are not similar in body size so that all Etawah-grade does can be maintained on each farm.

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.
