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: 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: 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.
