Abstrak: Cihateup duck is rm Indonesian local duck which is mostly found in West Java especially in Taskmlaya and Gamt Regency. Cihateup duck is h o w as a mountain duck became it can be adapted to cool temperatures and can survive in the high lands. The aim of this research was to get information about biolo~cch aracteristics of Cihateup ducks. Five hundred and seventeen Cihateup eggs from T a s i W y a and Garut were hatched. After hatching, the duck that used to treatments are 9 miles, 19 females duck from Tasikdaya and 35 males, 37 females duck from Garut. Commercial diet was gven with 2 periods i.e: starter and grower diet. Water and feed were given ad libitum. Characteristic of egg, body weight, average daily gain, feed consumwon and conversion, body measurements, plumage ptterns, shank and lxak colors, and b l d protein polymorphism were observed. The data of egg characteristics and growth pattern were analyzed with general linier model procedure by SAS 6.12. Body measurements were analyzed with Principal Component Analyze (PCA) by Minitab release 12.13. The data plumage patterns were analyzed with descriptive analyze. B l d proteins variation were analyzed to measure genetic variant and genetic &stance. The results showed that egg weight from TasWya (68.0 g) was more weight than those from Gamt (65,6 g). Egg index from Tasikmdaya (80.1 9%) and Gmt (79.67%) were not significantly different and both have normal egg index. Egg fertility from Gamt (6 1.0%) was higher than from Tasikmalaya (36.75%).Egg hatchability from Tasikmalaya (65.12%) was better than from Garut (52.46%). There were no differences of body weight and average daily gain of male and female Cihateup ducks. Feed consumption of male was higher than female but the feed conversion of males was better than the females. The male ducks from TasiWaya (88.89%) dm Garut (94.29%) have dominant plumage patterns penciled, whereas the female ducks from Tasikmalaya (63.16%) and Garut (64.86%) have dominant plumage pattern laced. Almost dl Cihateup ducks from Tashdaya male (88.89%) and female (89.47%) also h m Garut male (85.71 %) and female (91.89%) have black colored shanks and beaks and only some showed the yellow color. There were similarity of blood protein between Chteup duck from Tasilunalaya and Garut. The blood protein study showed a close relationship between the Tasikmalaya and Gruut Cihateup ducks.

Judul: Daya Tetas Telur Itik Cihateup dan Alabio
Abstrak: Local ducks in Indonesia such as alabio duck and cihateup duck have advantages as egg producer and meat producer. Efforts is needed to increase the population of ducks by doing hatching. This research is to learn the hatchability of alabio duck and cihateup duck and identify of the factors that can be affected hatching duck eggs. Eggs ducks used 200 grains eggs ducks cihateup and eggs ducks alabio 300 grains. The process of hatching the egg ducks held for 28 days. The percentage fertility and hatchability results duck eggs alabio higher than cihateup duck eggs. Death embryonic the biggest occurred on the day to 26-28 days. Greater egg weights produce larger DOD. Weight of eggs and duck eggs index has no effect on hatchability but which affect hatchability of duck eggs in this study is high temperature during incubation, lower humidity during the period hatcher and egg hygiene. Alabio duck egg weight is lighter than duck eggs cihateup and more oval shaped while cihateup duck eggs more rounded shape. Weight egg and index egg on two types of eggs uniforms.

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.
