Judul: Suplementasi Minyak Biji Bunga Matahari (Helianthus annus)pada Ransum Terhadap Konsumsi dan Penampilan Domba Garut Bunting
Abstrak: This research was conducted to evaluate effect of sunflower seed oil supplementation on feed intake and performance of ewe during pregnancy. This research used completely randomized design (CRD) with 4 treatments and 3 replicates. Treatments that used were P0 without sunflower seed oil,P1, P2, P3 were supplementedwith 2%, 4%, and 6 % sunflower seed oil respectively.Parameters observed in this experiment included dry matter intake, nutrient intake, daily body weight gain, feed efficiency and body condition score (BCS). Data were analyzed using analysis of variance (ANOVA).If means were significantly different, it would be further tested by Duncan multiple range test. The results showed that supplementation of sunflower seed oil did not effect different on nutrient intake, crude protein intake, weight gain, and feed efficiency but sunflower seed oil significantly affected intake of crude fat , crude fiber,calcium and phosphor. Supplementation of sunflower seed oil could improve BCS which was better than control.Suplementation sunflower seed oil untillevel 6% s canincrease fat intake, reduceintake of crude fiber, calsium and phosporbut it doesn't disturb the performance of pregnant Garut ewe.

Abstrak: The aim of this research was to determine the optimal level of sunflower seed oil in the diet that evaluated through measurement of nutrient digestibility in Garut ewes at the middle period of pregnancy. This research used completely randomized design and divided into four treatments. The treatments were P0 (without sunflower seed oil), P1 (2% of sunflower seed oil), P2 (4% of sunflower seed oil) and P3 (6% of sunflower seed oil). Data were analyzed by analysis of variance and any significant differences were further tested using polynomial orthogonal. The result showed that the treatments did not affect the consumption and digestibility of dry matter, crude protein, crude fiber, N-free extract, total digestible nutrients, average daily gain and feed efficiency, but its significantly affected (P<0.05) the consumption and digestibility of crude fat. It is concluded that the use of sunflower seed oil at 4% level could increase the consumption and digestibility of crude fat.

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
