Judul: Kecernaan Zat Makanan pada Domba Garut Bunting yang Diberi Ransum dengan Level Minyak Biji Bunga Matahari Berbeda
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: Karakteristik Estrus dan Tingkat Kebuntingan Domba Garut dengan Penambahan Minyak Biji Bunga Matahari (Helianthus annus) pada Ransum
Abstrak: The purpose of this research was to observe the garut sheep consumption of nutrients,characteristic responses and pregnancy rate which was given the addition of sunflower oil (Helianthus annuus) in the ration. The research was conducted based on completely randomized design with 4 treatments were P0 (control ), P1 (with 2 % addition of sunflower oil), P2 (with 4 % addition of sunflower oil), and P3 (with 6 % addition of sunflower oil ), and 8 replications. The data were analized by ANOVA and continued with Duncan test if there were mean differences. Analysis of data used SPSS 16.0 and presented descriptively. The result showed the addition of sunflower oil significantly (P<0.05) reduced dry matter consumption and very significant (P<0.01) reduced the consumption of crude protein, calcium, phosphor and increased crude fat. The fastest onset estrous found in P3 treatment and the longest estrous found in P1 treatment. The P2 treatment resulted in good response (75%) with the highest pregnancy rate (62.5%).

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.
