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: Kajim Kamkteristik Biologis Itik Cihateup
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: Pengembangan Sistem Rotasi Peta pada Perangkat Mobile tanpa Sensor Magnetometer
Abstrak: Due to the improvement of technology, the function of mobile phone has changed a lot. Nowadays, mobile phone is used not only for communication, but also to support the user’s activity. Many mobile phones now have Operating System (OS) and sensors like GPS and magnetometer. GPS is a sensor that can be used to identify any location, including the location of the user, while magnetometer can be used to identify direction. With data that come from GPS and magnetometer, we can build a navigation application that can rotate its map according to the rotation of the user. Meanwhile, in the Android Compability Definition Document point 1.6 until 2.2, Google have requirements for mobile phones to have GPS and magnetometer sensors if they want to use Android OS. But, since the release of 2.3.3 OS, Google has changed its requirements, allowing any mobile phones to have Android OS without having the magnetometer sensor. The objective of this research is to build an navigation application that can rotate without using magnetometer sensor. The value of the rotation degree is taken from last two position. To stabilize the value, Exponential Smoothing is used in filtering process. This system also use Haversine method to recognize whether the user is walking or driving/riding.
