Judul: Nutrient Digestibility of Late Pregnancy Local Ewes Fed  Flushing Ration with Different Frequency
Abstrak: Tujuan dari penelitian ini adalah mengevaluasi kecernaan nutrien pada domba lokal fase akhir kebuntingan yang diberi ransum flushing dengan frekuensi pemberian yang berbeda. Penelitian ini menggunakan 12 domba lokal fase akhir kebuntingan, dengan rataan bobot badan 49,96 kg ± 9,67. Penelitian ini menggunakan Rancangan acak kelompok (RAK) dengan 4 x 3, yaitu P1 (tanpa flushing), P2 (flushing pada saat sebelum dan sesudah kawin), P3 (flushing pada saat sebelum dan sesudah kawin, dan pertengahan kebuntingan), dan P4 (flushing pada saat sebelum dan sesudah kawin, pertengahan, dan akhir kebuntingan). Konsentrat flushing mengandung 2% minyak kelapa dan 5% minyak ikan lemuru. Parameter yang diukur yaitu konsumsi nutrien dan kecernaan nutrien. Data yang diperoleh dianalisis menggunakan ANOVA dan apabila berbeda nyata diuji lanjut menggunakan uji Duncan. Hasil menunjukkan perlakuan nyata mempengaruhi (P<0,05) konsumsi lemak kasar dan kecernaan bahan kering, protein kasar, serat kasar, dan BETN, tetapi tidak nyata mempengaruhi konsumsi bahan kering, protein kasar, serat kasar, dan BETN, serta kecernaan lemak kasar. P3 meningkatkan kecernaan bahan kering, protein kasar, serat kasar, dan BETN. P4 meningkatkan konsumsi lemak kasar dan cenderung meningkatkan kecernaan lemak kasar, The aim of this research was to evaluate the nutrient digestibility of late pregnancy local ewes given flushing ration with different frequency. This research used 12 local ewes in the late pregnancy, with average body weight 49,96 ± 9,67 kg. This research used a Randomized block design (RBD) with 4 x 3 . The treatments were P1 (without flushing), P2 (flushing at the before and after mating), P3 (flushing at the before and after mating, and middle of pregnancy), and P4 (flushing at the before and after mating, middle, and end of pregnancy). Concentrate flushing containing 2% coconut oil and 5% Lemuru fish oil. The measured parameters were nutrient consumption and nutrient digestibility. The data were analyzed using ANOVA and any significant differences were further tested using Duncan Test. The result showed that the treatments significantly affected (P<0,05) the consumption of crude fat and digestibility of dry matter, crude protein, crude fiber, and N-free extract, but it did not affect the consumption of dry matter, crude protein, crude fiber, and N-free extract, as well as the digestibility of crude fat. In conclusion, P3 increased digestibility of dry matter, crude protein, crude fiber, and N-free extract. P4 increased nutrient consumption of crude fat.

Judul: Physiological Response and Estrus Characteristics of Sumatran Composite Sheep that Given Flushing Ration at the Sumatera Martabe Farm
Abstrak: Penelitian ini bertujuan mempelajari pengaruh ransum flushing terhadap respon fisiologis dan karakteristik estrus induk Domba Komposit Sumatera di Sumatera Martabe Farm. Jumlah domba yang digunakan sebanyak 10 ekor induk domba Komposit Sumatera yang memiliki rata-rata bobot badan 43,41 kg/ekor, ditempatkan pada kandang individu. Perlakuan yang diberikan meliputi 2 ransum, yaitu ransum kontrol (SMF) dan ransum flushing (Flushing). Peubah yang diamati adalah respon fisiologis, konsumsi nutrien berdasarkan bobot badan metabolis, dan karakteristik estrus (onset estrus, durasi estrus, dan respon estrus). Data yang diperoleh dianalisis dengan t-test independent sample menggunakan program IBM SPSS Statistic 25. Hasil penelitian menunjukkan ransum flushing yang digunakan berpengaruh nyata (P<0,05) meningkatkan konsumsi nutrien, dan mempercepat onset estrus dan durasi estrus dibandingkan dengan ransum SMF, namun tidak berpengaruh nyata terhadap respon fisiologis pada Domba Komposit Sumatera. Ransum flushing dapat meningkatkan konsumsi nutrien, mempercepat onset estrus dan durasi estrus , namun tidak mengganggu status fisiologis dari induk Domba Komposit Sumatera, This research aimed to study the effect of flushing rations on the physiological response and estrus characteristics of Sumatran Composite Sheep at the Sumatera Martabe Farm. A total of 10 Sumatran Composite Sheep with an average body weight of 43,41 kg/ekor, were used and placed in individual pens. The treatments consisted of 2 groups: a control ration (SMF) and a flushing (Flushing). The variables observes were physiological response, nutrient consumption based on metabolic body weight, and estrus characteristic (onset of estrus, duration of estrus, and estrus response). The data obtained were analyzed by independent sample t-test using the IBM SPSS Statistic 25 Program. The results show that flushing diet significantly (P<0,05) increased nutrient consumption and accelerated onset and duration of estrus compared to the SMF diet. However it, did not significantly affect the physiological response of Sumatra Composite Sheep. The flushing diet can enchance nutrient consumption, accelerate onset and duration of estrus, without disrupting the physiological status of Sumatra Composite Sheep.

Judul: Implementasi hidden markov model untuk aplikasi pengenalan ucapan sebagai kendali gerak robot mobil
Abstrak: Robot is an electronic or mechanical equipment capable of performing a series of actions automatically. In the world of robotics, control systems is a very important part that serves to control the movement or navigation in a robot. Sound based mobile control system is an alternative voice control that is quite efficient. However, voice recognition process is not easily done by a machine. It needs a machine learning method that can be used to perform the voice feature extraction by studying the characteristics of a previous vote. This study uses Mel-Frequency Cepstral Coefficient (MFCC) to extract speech signal and HMM (Hidden Markov Model) for modeling the speech signal. Result of the experiment from the whole system performance speech recognition is 96,4% for people that have been inputted in the database, and 91,2% for people which have not been inputted in database. The mobile robot system test results showed that the system has worked well and has an average response time to move after the speech recognition process around 0,46 seconds.
