Judul: Karakteristik Ukuran Dan Bentuk Tubuh Domba Ekor Tipis Melalui Analisis Regresi Komponen Utama Di Up3j, Peternakan Tawakal Dan Mitra Tani
Abstrak: Sheep as a small ruminant is very popular among the farmers in Indonesia, because it is easy to take care of, can breed well and easily adaptable. The relationship between body weight and body measurements are neccessary needed to be studied. These body measurements can be used as a predictor of a live weight. Thirteen body measurements were taken on 198 Local sheep under the age of one year. As a result T2-Hotelling method indicated that the difference body measurements and gender group in each farm sheep (P <0.01). Principal Component Analysis (PCA) showed that a high shoulder size and shape that has the highest eigen vector (0.56 and 0.67) in the group of sheep UP3J. The chest circumference has the highest eigen vectors respectively (0.61 and 0.56) as a size in MT Farm and Tawakal Farm. The body lenght has the highest eigen vectors respectively (0.80 and 0.62) a shape in that farm. Based on observations of linear body size can also determine score and the score of the size of each individual were observed by principal component analysis approach that can distinguish the size and shape of the various groups of local sheep. Determination of linear body measurement variables that provide a beneficial effect on body weight can be obtained based on elasticity values derived. Principal component regression analysis results showed that body measurements in each groups of male and female sheep is the chest circumference.

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: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
