Judul: Provision of Flushing Rations at Different Phases of the Performance of the Ewes and Pre-weaning Lambs
Abstrak: Penelitian bertujuan menganalisis pengaruh pemberian ransum flushing pada fase berbeda terhadap performa induk dan anak domba pra-sapih. Penelitian menggunakan 12 ekor domba betina beranak kedua dan 18 ekor anak domba. Rancangan acak kelompok (RAK) 4 x 3 dengan perlakuan P1 = tanpa flushing, P2 = flushing sebelum dan sesudah kawin, P3 = flushing sebelum dan setelah kawin serta tengah kebuntingan, P4 = flushing sebelum dan setelah kawin, tengah serta akhir kebuntingan. Peubah yang diukur adalah konsumsi nutrien, bobot induk beranak, pertambahan bobot badan induk beranak, bobot lahir, bobot sapih, mortalitas dan pertambahan bobot badan harian anak pra-sapih. Data dianalisis dengan analisis ragam dan uji lanjut Duncan. Analisis deskriptif digunakan untuk mengetahui tingkat mortalitas. Pemberian ransum flushing pada fase berbeda nyata meningkatkan konsumsi lemak kasar dan PBHH anak umur 14 hari (P<0.05), namun, tidak berpengaruh nyata terhadap bobot induk pasca beranak, PBB induk beranak, bobot lahir, dan bobot sapih anak domba (P>0.05). Dapat disimpulkan bahwa pemberian ransum flushing P4 mampu meningkatkan konsumsi lemak kasar induk domba dan PBBH anak umur 14 hari., The aim of the study was to analyze the effect of giving flushing rations at different phases of the performance of pre-weaned broods and lambs. The study used 12 ewe lambs with second lambs and 18 lambs. Randomized block design (RBD) 4 x 3 with treatment P1 = no flushing, P2 = flushing before and after mating, P3 = flushing before and after mating and in the middle of pregnancy, P4 = flushing before and after mating, middle and end of pregnancy. The variables measured were nutrient consumption, calf weight, calf body weight gain, birth weight, weaning weight, mortality and daily body weight gain of pre-weaning cubs. Data were analyzed by analysis of variance and Duncan's further test. Descriptive analysis was used to determine the level of mortality. Provision of flushing rations in different phases significantly increased crude fat consumption and daily body weight gain of lambs aged 14 days (P<0.05), however, did not significantly affect post-calving brood weight, post-calving brood weight gain, birth weight, and body weight of weaning lambs (P>0.05). In conclusion, P4 was able to increase the consumption of crude fat of the ewes and the daily body weight gain of the lambs aged 14 days.

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.
