Judul: Effects of peri-mating and peri-partum supplementary feeding on the reproduction of indonesia female sheep  and goats
Abstrak: The aims of the research were : (1) to compare the reproductive rate and efficiencies of utilization of feed for reproduction of Etawah Cross Goats and Kacang Gbats maintained on low quality feed with and without supplementation during the pe/ri-mating and peri-kidding period, (2) to define the minimum period of peri mating and peri-lambing supplementary feeding needed for maximum reproductive performance for sheep maintained on low quality feed in a continuous mating system during two years, (3) to develop a comparison of reproductive performance between goats and sheep on the same treatments.

Judul: Performa Kambing Peranakan Etawah Muda dan Produktivitas Induk Laktasi dengan Sistem Pemberian Pakan yang Berbeda di Lahan Pasca Galian Pasir
Abstrak: This study aimed to examine the effect of different feeding systems on post-mining of sand land performance of young Peranakan Etawah goat and lactation productivity of Etawah ewe The study used 12 goats (12,592 ± 1,326 kg) within 3-6 months of age. There were two factor of treatment. Treatment one was differences of eating time (W1 = 08.00 a.m to 04.00 p.m and W2 = 02.00 p.m to 04.00 p.m). Treatment two was type of feed (P1 = 100 g/day concentrate and forage, P2 = forage). Protein content of concentrate was 19,32% and forage affered ad libitum. The data were analyzed descriptevely for dry matter intake, feed eficiency and Income Over Feed Cost (IOFC) but the method for daily Body Weight Gain (BWG) used in this study was 2x2 factorial completely randomized design. The results showed that BWG of goats was significantly different among treatment (P<0,01). There was interaction betwent W & P trial. Daily BWG was significantly higher in trial W1 and P1 as well as IOFC with average daily BWG is 74,41 ± 11,89 and IOFC is Rp. 249.666,67. Subsequent study on the lactation productivity Etawah ewe of different feeding systems. This study used 15 goats within 10 goats in lactation two and 5 goats in lactation three. Treatment was differences type of feed (P1 = forage, P2 = forage and food industry waste). The data feed consumption were analyzed descriptevely. Data production and milk quality were analyzed using t test. Dry matter of milk was very significant higher (P<0,01) in ration added food industry waste than ration without food industry waste adition, while protein content and fat in milk was significant (P<0,05).

Judul: Pemodelan chord pada piano menggunakan metode fuzzy learning vector quantization
Abstrak: Seorang pemain piano pemula maupun autodidak umumnya belum melalui tahap latihan yang baik sehingga kemampuan untuk mengenali chord yang dimiliki masih kurang. Oleh karena itu, suatu sistem yang dapat mengenali chord untuk membantu proses pemahaman chord yang dimainkan dibutuhkan. Penelitian ini memodelkan chord yang terdiri atas 3 nada (triad) ke dalam beberapa kelas. Data yang digunakan dalam penelitian ini adalah 24 chord mayor dan minor. Data training dan data testing divariasikan dalam 4 model menggunakan 5-fold crossvalidation. Ekstraksi ciri akan dilakukan dengan metode Mel Frequency Cepstrum Coefficients, dan klasifikasi akan dilakukan dengan metode Fuzzy Learning Vector Quantization (FLVQ). Pemodelan FLVQ dilakukan dengan melakukan variasi pada learning rate serta koefisien fuzzyness. Penelitian ini telah berhasil membentuk model FLVQ dengan akurasi rata-rata 79.38% serta akurasi maksimum 100%. Akurasi maksimum dicapai dengan nilai learning rate α sebesar 0.05 dan koefisien fuzzyness β sebesar 0.05 menggunakan epoch sebanyak 20 pada FLVQ model 2.
