Judul: The Effect of Different Flushing Feed Management on Local Ewes Hematology at the End of Pregnancy
Abstrak: Penelitian ini bertujuan menganalisis efek dari manajemen pakan flushing yang berbeda pada hematologi domba lokal di akhir kebuntingan. Ternak yang digunakan sebanyak 12 ekor domba lokal betina laktasi kedua dengan berat rata- rata 29,75 ± 6,02 kg dan ditempatkan di kandang individu. Penelitian menggunakan Rancangan Acak Kelompok 4 x 3 yang dikelompokkan berdasarkan bobot badan ternak. Perlakuan terdiri atas P1 = Tanpa flushing, P2 = Flushing sebelum dan setelah kawin, P3 = Flushing sebelum dan setelah kawin serta tengah kebuntingan, P4 = Flushing sebelum dan setelah kawin, tengah serta akhir kebuntingan. Perbandingan hijauan dan konsentrat dalam ransum adalah 30:70 berdasarkan bahan kering. Parameter yang diamati adalah hematokrit, kadar hemoglobin, Butir Darah Merah (BDM), Butir Darah Putih (BDP), dan persentase diferensiasi leukosit yang terdiri dari limfosit, monosit, neutrofil, basofil, dan eosinofil. Analisis data menggunakan uji ANOVA dan Duncan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0,05) terhadap hematokrit, kadar hemoglobin, Butir Darah Merah (BDM), dan diferensiasi leukosit. Manajemen flushing berpengaruh signifikan (P<0,05) terhadap Butir Darah Putih (BDP). Dapat disimpulkan flushing sebelum dan setelah kawin, tengah dan akhir kebuntingan meningkatkan nilai hematologi ternak dibandingkan dengan perlakuan tanpa flushing, flushing sebelum dan sesudah kawin, flushing sebelum dan sesudah kawin serta tengah kebuntingan., This study was aimed to analyze the effects of different flushing feed management on the hematology of local sheep at the end of pregnancy. This research used 12 second lactating local ewes, average weight was 29,75 ± 6,20 kg and placed in individual cages. This research used a randomized block design (RBD) with 4x3 that are grouped based on body weight of ewes. The treatments consisted of P1 = without flushing, P2 = flushing during before and after matting, P3 = flushing during before and after matting, and in the middle of pregnancy, P4 = flushing during before and after matting, in the middle and end of pregnancy. Ratio forages and concentrate in the ration were, 30:70 % dry matter basis. The parameter observed were hematocrit, hemoglobin level, Red Blood Cell (RBC), White Blood Cell (WBC), and leukocyte diferentation consisting of lymphocytes, monocytes, neutrophils, basophils, and eosinophils. The data were analyzed using ANOVA and Duncan test. The results showed that the treatment did not significant effect (P>0,05) on hematocrit, level hemoglobin, Red Blood Cell, and leukocyte diferentation. Flushing management had significant effect (P<0,05) on White Blood Cell (WBC). This study concluded that treatment with flushing before and after mating, midle of pregnancy and end of pregnancy increases hematological value of cattle compared to treatments without flushing, flushing before and after mating, and flushing before and after mating, midle of pregnancy.

Judul: Blood Metabolites of Lamb and Ewes Postpartum with Different Management Flushing Rations
Abstrak: Penelitian bertujuan mengevaluasi kadar metabolit darah anak dan induk domba pasca beranak dengan manajemen pemberian ransum flushing pada fase yang berbeda. Ternak yang digunakan 12 ekor domba betina beranak kedua bobot badan 30,06 ± 6,20 kg dan 18 ekor anak domba bobot lahir 2,49 ± 0,56 kg yang dipelihara bersama induknya sampai umur sapih 60 hari. Penelitian menggunakan Rancangan Acak Kelompok dengan 4 perlakuan dan 3 ulangan. Perlakuan terdiri atas P1 = Tanpa flushing, P2 = Flushing sebelum-setelah kawin, P3 = Flushing sebelum-setelah kawin serta tengah kebuntingan, P4 = Flushing sebelum-setelah kawin, tengah serta akhir kebuntingan. Peubah yang diamati meliputi kadar glukosa, kolesterol, trigliserida dan nitrogen urea plasma. Data dianalisis dengan ANOVA dan dilanjutkan uji lanjut Duncan. Hasil penelitian menunjukan bahwa manajemen flushing yang berbeda tidak berpengaruh nyata terhadap kadar glukosa, kolesterol, trigliserida dan nitrogen urea plasma anak dan induk domba pasca beranak (P>0,05). Dapat disimpulkan bahwa manajemen pemberian ransum flushing pada fase yang berbeda yaitu satu kali (prakawin-awal kebuntingan), dua kali (prakawin-awal dan ditengah kebuntingan), serta tiga kali (prakawin-awal, ditengah dan diakhir kebuntingan) tidak mempengaruhi kadar metabolit darah anak dan induk domba pasca beranak., This study was aimed to evaluate blood metabolites levels of pre-weaning lamb and ewes postpartum with management of flushing rations in the phase different. This research used 12 partus local ewes (body weight 30,06 ± 6,20 kg) and 18 new birth lambs (birth weight 2,49 ± 0,56 kg) kept with their mother until the age of 60 days. A randomized block design with 4 treatments and 3 replications was used in this study. The treatments consisted of P1= without flushing, P2 = flushing before-after mating, P3 = flushing before-after mating, midle of pregnancy, and P4 = flushing before-after mating, midle of pregnancy and end of pregnancy. The levels of blood glucose, cholesterol, triglycerides and BUN were observed. The data were analyzed using ANOVA and followed by Duncan test. Different flushing management had no significant effect on the concentration of blood glucose, cholesterol, triglycerides and BUN of lamb and ewes postpartum (P>0.05). It can be concluded that the management of flushing rations in the phase different, namely one time (pre-mating-early of pregnancy), two times (pre-mating-early and middle of pregnancy) and three time (pre-mating-early, middle and end of pregnancy) does not affect blood metabolites levels of lamb and ewes postpartum.

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.
