Judul: Ukuran dan Bentuk Tubuh pada Domba Ekor Tipis, Domba Batur, Domba Wonosobo dan Domba Garut
Abstrak: Sheep potentially large as producing meat and wool for the public need the world. The research aimed to obtain genetic information morphometric characteristics based on size and shape body of Thin-tailed sheep (DET), Batur sheep (Dombat), Wonosobo sheep (Dombos), and Garut sheep (Fighting-type and Meat-production-type) that aged 1.5-2.0 years. Data obtained by measuring the linear body measurements sheep and processed with descriptive statistics, statistical T2-hotelling and principal component analysis. Result showed that body surface linear measurements were significantly different (P<0.01) between breeds. Principal component analysis resulted shoulder height was the size discriminator on DET, Dombat, Dombos, Fighting-type Garut and Meat-producing-type Garut sheep. Hip height was the size discriminator on DET, Fighting-type Garut and Meat-producing-type Garut sheep. Body length was the size discriminator on Dombat and Dombos. Shoulder height is a form discriminator on DET and Fighting-type Garut sheep. Body length is the shape discriminator on Dombat, Dombos and Meat-producing-type Garut sheep. Hip height is a form discriminator in Dombos while chest wid this a form discriminator in Meat-producing-type Garut sheep. Group diagram showed that the individual data for each sheep was unique because it formedits own group. Data group all sheep intersecting against DET, this shows that all sheep research had blood DET as their elders.

Judul: Analisis Diskriminan Ukuran Tubuh Betina pada Domba Ekor Tipis Batur Wonosobo dan Garut
Abstrak: The purpose of this research was to evaluated the differences among morphometric characteristics of Thin-Tailed, Batur, Wonosobo and Garut (fighting and meat types) ewes. Variables be observed were shoulder height, hip height, body lenght, chest width, chest depth, hip width, rump width, rump length, metatarsus length, metacarpus length and cannon circumference. Number of sheep be observed were 79 heads. The data was analyzed with T2-Hotelling test, fisher discriminan analysis, Wald-anderson and D2-Mahalanobis minimum distance. Discriminator variable between Batur vs Garut meat type was cannon circumference, Batur vs Garut fighting type was shoulder height and cannon circumference, Batur vs Wonosobo was hip width, Thin-Tail vs Batur was body length, Thin-Tailed vs Garut meat type was shoulder height, Thin-Tailed vs Garut fighting type was shoulder height, Thin-Tailed vs Wonosobo was body length, chest width, hip width, rump width , rump length, Wonosobo vs Garut meat type was hip width. Unsimilarity distance between Batur and Garut meat ewes, type was 4.058, Batur and Garut fighting type was 2.278, Thin-Tailed and Batur was 3.950, Thin-Tailed and Garut meat type was 2.758, Thin-Tailed and Garut fighting type was 2.921, Thin-Tailed and Wonosobo was 4.748, Wonosobo and Garut meat type was 2.204. Thin-Tailed was separated from the others. Wonosobo formed a group together with Garut. Garut fighting and meat types was not separated because it was a group of Garut Sheep. Garut and Wonosobo formed one group that separated from Batur.

Judul: Sintesis 1-Kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai Prekursor Asam (S)-(+)-(6-Metoksi-2-naftil)propanoat
Abstrak: Senyawa 1-kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai prekursor asam (S)-(+)-(6-metoksi-2-naftil)propanoat disintesis dari bahan awal 2-metoksinaftalena. Tahapan sintesis diawali dengan klorinasi menggunakan 2 jenis pereaksi klorinasi, yakni isosianurat terklorinasi dan NaOCl. Klorinasi dengan isosianurat terklorinasi berhasil menyintesis 1-kloro-2-metoksinaftalena sebagai produk monoklorinasi melalui pencirian dengan kromatograf gas-spektrometer massa (GC-MS). Nisbah konversi produk paling efisien diperoleh pada laju penambahan 2.5 mmol/jam. Sebaliknya, klorinasi dengan NaOCl menghasilkan produk triklorinasi. 1-Kloro-2-metoksinaftalena selanjutnya diasilasi dengan propanoil klorida, tetapi analisis dengan GC menunjukkan bahwa produk asilasi tidak terbentuk. Sistem bebas-air diperlukan untuk keberhasilan proses asilasi tersebut.
