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: Pengembangan Model Codebook untuk Identifikasi Chord Gitar
Abstrak: Acoustic guitar can produce sound waves with different types of tones. High-low tone is determined by the fundamental frequency of the sound wave. Human sense of hearing can distinguish high-and low tones, but can not know for sure what kind of tone is heard by him. This study developed a guitar chord recognition system. This study uses MFCC as feature extraction methods and the codebook as pattern recognition method for identification of the guitar chord. Cluster technique used in this study is the K-means clustering. Data obtained from MFCC are clustered using the K-Means method, and the model for classification is constructed using the codebook method. The parameters used in MFCC is the number of cepstral coefficients, overlap, and the time frame, while an important parameter in the K-Means is the number of clusters. This study uses 8640 guitar chord sounds from 24 classes. Each of the data is made up of two chords which will be tested. Simulation results show that the maximum accuracy obtained is 98.89% obtained on 26 cepstral coefficients, overlap 0.4, time frame is 30 ms, on 100 clusters.
