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.

Abstrak: Cihateup duck is a primary duck of West Java that has been known as layer duck. It was lived at high land on cool temperature and mostly found is Tasikmalaya and Garut regency. This duck has not been known about of its biological characteristics yet. The aim of this research was to obtain information of production performance of Cihateup duck, which can be used as a reference for the animals development. Twelve female, 5 males ducks from Tasikmalaya regency and 31 females, 19 males ducks from Garut regency were used in this research. Commercial diet with 16% crude protein was given to the experimental animals. Water and feed were provided ad libitum. The data characteristic of production and fertility were analyzed with t-test by minitab release 13.20. Ratio of male duck and female duck was analyzed with X2 test. Correlation between production and fertility was analyzed with regretion by SAS 6.12. The result showed that Cihateup ducks are potential to be layer type. Perform of production that consist maturity age showed earlier. Average og body weight maturity of Cihateup ducks were 1 500-1 550 g. Peak production of Cihateup ducks were occured at third week (81.05±2.21 %) with potential production upper 60 %. Width of pubic bones Cihateup duck was 6 cm. Reproduction performs could be estimated from number of ova (772.17±663.60 eggs). The result showed that both of ducks had high potential egg production. Fertility of ducks were high, and there were similarity of male and female DOD. There were correlation between production and reproduction in Cihateup duck. This correlation values could be used to estimate production by reproduction traits.

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.
