Judul: Efek Pemberian Musik Klasik terhadap Produksi dan Komposisi Susu Sapi Fries Holland
Abstrak: Milk production in Indonesia did not been able to meet all consumer needs. Production and composition of cow's milk could be improved in various ways. Several studies in the UK showed that using classical music can make cows feel calm. Therefore, this study was carried out to determine the effect of classical music on the production and composition of milk. The study was done for 45 days, divided into 3 periods: pretreatment period, treatedperiod, and post period of classical music. The results showed that there was a significant increased in milk production. Tests on the milk compositions parameters of protein, lactose, solid, and density was not significantly different (P> 0.05), but the fat content was significantly increased (P <0.05).

Judul: Pengaruh Musik Klasik Terhadap Respon Fisiologis dan Lama Istirahat Sapi Fries Holland pada Siang Hari
Abstrak: A study using 4 cows was done to know the effect of classical music on physiological responses of Fries Holland (FH) cows. Heart rate, respiration rate and resting time were measured for 15 days at 12.00 – 15.30. The study was done for 45 days that divided into 3 periods. The first 15 days period as before treatment, a second 15-day as treatment period, and the rest 15 after treatment period. The data were analyzed by t-test: paired two sample for means. The results showed there was a decreasing in heart rate on the before treatment period 83 ± 6 times/minute to 76 ± 9 times/minute during treatment period. The similiar result was also found in respiration rate, there was a decreasing in the before treatment period from 56 ± 11 times/minute to 50 ± 15 times/minute as a treatment period. There was enlongation of resting time during the second period compare to the other period. Classical music increased the length of resting time from 26 ± 17 minutes in before treatment period to 27 ± 16 minutes during treatment period. It was concluded that classical music can decrease heart rate and respiration rate. The Classical music also can make dairy cattle calm and take rest longer

Judul: Penentuan Posisi Autonomous Underwater Vehicle (AUV) dengan Metode Dead Reckoning
Abstrak: AUV adalah wahana otonom bawah air yang memiliki berbagai sensor untuk akuisisi data. Alat ini dapat memudahkan survey bawah air karena bentuknya yang ringan. Misi AUV dibuat lalu disimpan ke dalam memori AUV. Penyelesaian misi memerlukan sistem navigasi yang akurat. GPS tidak bisa bekerja di dalam air sehingga dibutuhkan metode navigasi selain GPS. Dead reckoning adalah metode penentuan posisi dengan menghitung arah dan gerak AUV. Persamaan model kecepatan konstan digunakan untuk mengestimasi posisi pada saat t. Akurasi metode ini dipengaruhi banyak hal termasuk kesalahan sensor dan kondisi lingkungan. Misi dilakukan dalam 2 jalur berbeda sebanyak 3 kali. Jalur yang memiliki panjang lebih besar mempunyai kesalahan posisi yang tinggi. Ha ini disebabkan galat yang dihasilkan dead reckoning terakumulasi selama misi. Kesalahan tersebut dapat diatasi dengan memperhitungkan kondisi lingkungan pada program dead reckoning.
