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: Detoksifikasi Bungkil Biji Jarak Pagar (Jatropha curcas L.) dan Evaluasinya Secara in vitro dan in vivo terhadap Mencit (Mus musculus)
Abstrak: Jatropha curcas L. seed cake is a byproduct of the extraction process jatropha seeds to obtain oil from Jatropha (Jatropha oil). Production of jatropha oil from jatropha seeds, produces cake about 65-70% of the treated seeds. Jatropha curcas L. seed cake has very high proteins that are 56.4-63.8%. The very high protein content causes Jatropha curcas L. seed cake has the potential to be used as animal feed. However, some toxic compounds, especially phorbol ester can disrupt the digestive process and cause of death for cattle in a short time. This research aimed to obtain the best detoxification method and to determine the effects of its use in mice (Mus musculus). This research was initiated by proximate analysis on Jatropha curcas seed cake before detoxified. Detoxification consist of two methods of transesterification which includes of three treatment (transesterification followed by washing with water, transesterification followed by washing with hexane, and transesterification followed by washing with methanol) and solvent extraction includes four treatments (extraction of hexane- extraction of methanol-heating at temperature 60-80°C, extraction of hexane- extraction of methanol-autoclave at 121°C for 30 min, soaking NaOH- autoclave at 121°C for 30 min, and control autoclaved at 121°C for 30 min). Jatropha curcas seed cake which had been detoxified, then analyzed the content of phorbol ester and in vitro in rumen fluid. Jatropha curcas seed cake which contains the lowest phorbol ester then be tested in mice. Before detoxification, the phorbol ester of jatropha seed cake was about 795.78 mg / g meal. The results showed that detoxification could reduce the phorbol ester. Transesterification with methanol produced the lowest phorbol ester until 0.00 mg / g meal. Jatropha curcas seed cake result of transesterification with methanol washing was added to the diets of mice at levels of 0%, 5%, 10%, 15% and 10% containing 2.5% zeolite. The measured parameters was weight gain, mortality, food intake and digestibility, Protein Eficiency Ratio (PER) and Food Transformation Index (FTI). The results showed that the substitution of results of Jatropha curcas seed cake detoxification throughed the process of transesterification with methanol leaching into the diets of mice significantly affected the level of consumption of food substances. The best treatment was indicated by the ration with R3 treatment (15%)

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%.
