Judul: Differences in Body Measurements of Etawah Grade Does I3 at Doa Anak Yatim (DAY) Farm in Bogor and BPTU-HPT Pelaihari in Pelaihari
Abstrak: Kambing PE (Peranakan Etawah) merupakan hasil grading-up antara kambing Kacang dan Etawah. Penelitian ini menggunakan data sekunder kambing PE betina induk I3 (3−4 tahun) yang meliputi 30 ekor di peternakan Doa Anak Yatim (DAY) Bogor dan 34 ekor di BPTU-HPT (Balai Pembibitan Ternak UnggulHijauan Pakan Ternak) Pelaihari. Penelitian ini bertujuan menentukan variabel pembeda ukuran permukaan tubuh linear antara kambing PE di peternakan DAY Bogor dan BPTU-HPT Pelaihari. Data dianalisis deskriptif dan perbedaan ukuran permukaan tubuh linearnya dianalisis statistik T2 ˗Hotelling. Variabel pembeda kambing PE diperoleh melalui analisis diskriminan Fisher, sedangkan untuk mengklasifikasikan data kambing PE pada kedua peternakan tersebut melalui statistik Wald-Anderson. Variabel yang diukur: 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). Statistik T 2 ˗Hotelling menunjukkan perbedaan (P<0,01) antara kambing PE di peternakan DAY Bogor dan BPTU-HPT Pelaihari. Tinggi pundak, tinggi pinggul, panjang pinggul, dan lingkar dada merupakan variabel pembeda karena proses adaptasi, sehingga persamaan diskriminannya Ŷ=−0.14304X1−0.70203X2+4.24812X7+0.19356X8. Statistik Wald-Anderson menyatakan satu ekor kambing PE di peternakan DAY Bogor memiliki skor WaldAnderson seperti di BPTU-HPT Pelaihari dan satu ekor kambing PE di BPTU-HPT Pelaihari memiliki skor Wald-Anderson seperti di peternakan DAY Bogor.

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: Sintesis Krisin dari Floroglusinol
Abstrak: Flavone is a class of flavonoid, widely distributed in vascular plants. Flavones containing hydroxyl groups at 5 and 7 position are quite important regarding their biological activities and their abiquity in nature. Flavone having hydroxyl groups only at position 5 and 7 or 5,7-dihydroxyflavone is known as chrysin. In this study, crude chrysin had been successfully synthesized in 3 steps from phloroglucinol as starting material. Phloroglucinol was acetylated with acetonitrile and HCl gas, resulting phloroacetophenone amount to 74%. Phloroacetophenone benzoylation with 4.5 equivalents of benzoyl chloride produced tribenzoyl phloroacetophenone in 103–107% of yield and the subsequent Baker-Venkataraman rearrangement of the ester by using KOH in dried pyridine produced crude chrysin, with conversion percentage of 71.62%. All synthetic products had been characterized by melting point and spectroscopically.
