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: Discriminator Variables of Linear Body Measurements on Etawah-grade Does at Sahid Farm Bogor and BPTU-HPT Pelaihari
Abstrak: Kambing PE (Peranakan Etawah) telah menyebar ke berbagai daerah di Indonesia dengan lingkungan yang berbeda-beda. Adaptasi terhadap lingkungan berakibat pada perbedaan ukuran permukaan tubuh linear pada kambing PE. Ukuran permukaan tubuh linear merupakan salah satu sifat kuantitatif yang ditentukan banyak pasang gen (poligenik) dan sangat dipengaruhi lingkungan. Penelitian ini bertujuan untuk mempelajari dan menentukan variabel pembeda kambing PE induk betina pada kondisi gigi I3 antara peternakan Sahid dan Balai Pembibitan Ternak Unggul Hijauan Pakan Ternak (BPTU-HPT) Pelaihari, dengan menggunakan analisis diskriminan. Data sekunder yang diperoleh dari Laboratorium Pemuliaan dan Genetika Ternak Fakultas Peternakan IPB University, digunakan pada penelitian ini. Variabel yang diukur adalah 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 Wald-Anderson. Variabel pembeda ukuran permukaan tubuh linear kambing PE induk betina I3 peternakan Sahid dan BPTU-HPT Pelaihari yaitu tinggi pinggul (X2), lebar dada (X4), lebar pinggul (X6), panjang pinggul (X7), dan lingkar kanon (X9). Penggolongan Wald-Anderson menunjukkan satu kambing PE induk betina I3 di BPTU-HPT Pelaihari memiliki kemiripan ukuran tubuh dengan kambing PE induk betina I3 di peternakan Sahid., Etawah-grade (Peranakan Etawah or PE) has dispersed to some regions in Indonesia, where each region has a different environment. Adaptation to the environment causes Etawah Grade goat (PE) variations in linear body surface measurement depending on the region. Linear body surface measurements are quantitative traits determined by some gene pairs (polygenic) and highly influenced by the environment. This research aims to study and determine the discriminator variables of Etawah-grade does between Sahid farm and BPTU-HPT Pelaihari using discriminant analysis. The data will be used in this study as secondary data, obtained from Animal Breeding and Genetics Laboratory, Faculty of Animal Science, IPB University. The measured variables will be 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 using descriptive statistics, T2˗Hotelling, discriminant analysis Fisher, and Wald-Anderson. The discriminator variables among linear body surface measurements of Etawah-grade does between Sahid farm and BPTU-HPT Pelaihari are hip height (X2), chest width (X4), hip-width (X6), hip-length (X7), and cannon circumference (X9). The classification of Wald-Anderson showed that one Etawah-grade does on BPTU-HPT Pelaihari has a similar body size to the Etawah-grade does on Sahid 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.
