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: Variabel Pembeda Ukuran Permukaan Kepala Linear Kambing Peranakan Etawah (PE) Betina Induk di Empat Peternakan.
Abstrak: Morfometrik kepala kambing PE betina induk bersifat mewaris pada setiap kelompok ternak dengan letak geografis berbeda. Variabel pembeda antara kelompok ternak dapat digunakan sebagai referensi pembeda untuk pengelolaan kambing PE betina induk sesuai dengan lokasi peternakan. Penelitian dilakukan di BBPTU HPT Baturraden, BPTU Pelaihari, peternakan Caprito, dan Sahid. Variabel yang diukur: akrokranion-prosthion (X1), basion-prosthion (X2), panjang rahang bawah (X3), tinggi kepala (X4), tuber facial kiri-kanan (X5), nasion-rhinion (X6), entorbitale kiri-kanan (X7), euryon kiri-kanan (X8), dan supraorbitale kiri-kanan (X9). Data dianalisis menggunakan statistik T2-Hotelling, analisis diskriminan Fisher, analisis Wald-Anderson, dan D2-Mahalanobis. Fungsi diskriminan yang dibentuk di Baturraden vs Pelaihari: 𝑌̂= –3.48X1+8.61X2+2.43X3+5.39X4–5.27X5–6.37X6+8.9X8+5.72X9; di Caprito vs Baturraden: 𝑌̂= –1.57X3–1.83X4+3.25X8; di Caprito vs Pelaihari: 𝑌̂= –2.31X1+7.38X2–7.2X5–3.06X6+6.05X8+2.32X9; di Sahid vs Baturraden: 𝑌̂= –1.25X3–1.03X4; di Sahid vs Pelaihari: 𝑌̂= 4.81X2–4.64X3–4.79X5+5.37X8+1.96X9. Jarak minimum Mahalanobis yang diperoleh dari fungsi diskriminan digunakan membentuk dendogram ketidakserupaan morfometrik kepala kambing PE betina induk.

Judul: Isolasi senyawa sinamaldehida dari minyak kulit kayu manis sedagai antioksidan
Abstrak: Cinnamaldehyde is a major essential oil component of cinnamon bark. Cinnamon oil was isolated by using water distillation method that yielded 0.93% (w/w) or 0.95% (v/w). Gas chromatography mass spectrometry (GCMS) of cinnamon oil showed that the main component of the oil is a trans-cinnamaldehyde 32.8% and 3-phenyl-2-propenal 22.9%. The oil was further isolated for cinnamaldehyde by using preparative thin layer chromatography method at Rf of 0.62. GCMS analysis showed that cinnamaldehyde content was 89.1%. Furthermore, the cinnamaldehyde was tested for its antioxidant activity. The isolated product has antioxidant activity with IC50 of 5.06 mg/L as compared with positive control using butylated hydroxytoluene, which has the activity of 10.4 mg/L.
