Judul: Pengaruh taraf penggunaan bungkil biji jarak pagar (Jatropha curcas L.) dalam ransum terhadap penampilan reproduksi mencit (Mus musculus)
Abstrak: This experiment was conducted to study the effect of Jatropha curcas L. seed cake at different levels (0, 5, 10 and 15%) in the diet of mice (Mus musculus) on its reproductive performance. The variables observed were feed consumption, litter size a birth and weaning, birth and weaning weight, mortality rate. The result showed that Jatropha curcas L. seed cake levels in ration had no significant effects on feed consmuption. litter size at birth, birth and weaning weight, but produced significant effect (P<0.05) on litter size at weaning and highly significant effects (P<0.01) on mortality rate.

Judul: Bio-assay bungkil biji jarak pagar (Jatropha curcas) terdetoksifikasi menggunakan mencit (Mus musculus) sebagai hewan coba
Abstrak: A research to examine the effect of detoxified Jatropha curcas meal from several origins in mice diets (Mus musculus) had been conducted. The amounts of 144 mice were kept in 48 pens and completely randomized to a 3 x 6 factorial treatments. As factor A was Jatropha meal origins (A1 = Kebumen; A2 = Lampung and A3 = Lombok), while factor B was substitution of 10% soybean oil meal with Jatropha meal after detoxified with various methods (B0 = control diets without Jatropha; B1 = heat treatment of Jatropha + 1% turmeric meal; B2, B3 and B4 = addition of 0.5%, 1% and 1.5% turmeric meal respectively and then followed by heat treatments, B5 = addition 4% NaOH + 10% NaOCl followed by heat treatment. The treatments were repeated three times. Diet and nutrients intake, body weight changed and mortality had been measured. Jatropha of Lampung’s origin was less toxic in compare to Kebumen’s and Lombok’s origin. Jatropha origins and detoxification methods influenced diets intake, mice growth and mortality significantly (p < 0.05). Detoxified of Jatropha’s Lampung-origin with B5 method gave the highest survival rate (100%) of the mice after 28 d of feeding trial. The B5 was the best Jatropha detoxification methods in lowering phorbolester content but the meal still could not be categorized as a safe feed to consume.

Judul: Rancang Bangun Sistem Komunikasi Data Lokasi Robot Beroda dan Server Berbasis Wi-Fi Menggunakan Modul ESP8266
Abstrak: Robot beroda merupakan salah satu jenis robot yang banyak dikembangkan. Sistem komunikasi data antara robot dan server banyak diterapkan pada sistem kerjasama antar-robot, ketika robot memerlukan informasi terkait robot lainnya. Penelitian ini mengembangkan sistem komunikasi data nirkabel berbasis Wi-Fi menggunakan modul ESP8266. Data diambil menggunakan modul GPS Ublox Neo 6MV2 yang terhubung dengan satelit lalu dikirim dan disimpan di server untuk kemudian digunakan sesuai kebutuhan. Selanjutnya, pengiriman data dari server ke robot disimulasikan dengan pengiriman balasan oleh server bahwa data sudah diterima. Selanjutnya robot akan merespon balasan dari server tersebut dengan menyalakan light emitting diode (LED) sebagai notifikasi. Hasil dari penelitian ini adalah sistem komunikasi data secara real time dengan menggunakan modul ESP8266 berhasil diimplementasikan dengan interval pengiriman data sebesar 33.29ms dan tingkat keberhasilan pengiriman data keseluruhan sebesar 100%.
