Judul: Evaluasi Kecernaan Total dan Kadar Nutrien Daging Ikan Mas (Cyprinus carpio) yang Diberi Pakan Mengandung Tepung Daun Kayu manis (Cinnamomum burmanni)
Abstrak: The study evaluated the effect of cinnamon leaf powder addition affect to total digestibility and nutrient content of common carp (Cyprinus carpio). The fishes at average weight of 18.05±0.36 g were distributed to each aquarium (50 x40x35 cm3). The treatment conducted for 40 days with different level of cinnamon leaf powder mixture (0.0%, 0.5%, 1%, dan 1.5%). The feed was given three times per day with ad satiation method. All of the treatments replicate by three times. The result was given that the cinnamon leaf powder addition enhances the consumption rate for fish but not influence for the fish growth. The conclusion, the addition of cinnamon leaf powder in 1.5% decrease the total feed digestibility. Otherwise, the addition of cinnamon leaf powder increases protein and fat in fish meat.

Judul: Pengaruh Pemberian Kayu Manis terhadap Kinerja Pertumbuhan dan Kualitas Daging Ikan Mas
Abstrak: This research was carried out to evaluate the effect of Cinnammomun burmanni as a supplement in the diet on the growth performance and flesh quality of the common carp Cyprinus carpio. A triplicate experiment was conducted using fish with an initial body weight of 7,88 ± 1,41 g. Fish were culture in aquaria 50x40x35 cm3 at a density of 10 fish/aquaria. Fish were fed on the diet contained either 0%,0,25%, 0,5%, 0,75%, or 1% respectively. Fish fed on the diet at satiation for 37 days. The results showed that the addition of Cinnammomun burmanni in the diet from 0% to 1% was insignificantly affected the growth and survival rate of fish. However, the addition of Cinnamomumn burmanni reduced feed efficiency. On the other hand, fish flavor and flesh texture were affected by the addition of Cinnamomun burmanni in the diet. The diet of 0,75% Cinnamomumn burmanni were the optimal result of this research with the sweet flavor and compact texture.

Judul: Karakteristik Horizontal Gelombang Kelvin Dan Rossby-Gravity Di Lapisan Stratosfer-Bawah Ekuatorial Pada Fase Baratan Dan Timuran Qbo
Abstrak: Data ERA-Interim dengan periode 35 tahun (Januari 1979 – Desember 2013) keluaran ECMWF (European Center for Medium Range Weather Forecasts) digunakan untuk menganalisis karakteristik gelombang Kelvin dan gelombang Rossby-Gravity pada fase baratan dan timuran QBO menggunakan metode Space-Time Spectral Analysis (STSA). Hasil dari penelitian ini menunjukkan bahwa aktivitas gelombang Kelvin menguat pada fase timuran QBO dan gelombang Rossby-Gravity menguat pada fase baratan QBO di lapisan stratosfer-bawah. Variasi musiman menunjukkan bahwa aktivitas kedua geombang tersebut menguat pada musim JJA dan SON akibat profil aliran dasar yang berada di lapisan stratosfer dan diperkuat dengan proses konveksi di wilayah Pasifik tropis. Identifikasi gelombang Kelvin dan Rossby-Gravity juga dilakukan di lapisan troposfer untuk membandingkan karakteristik kedua gelombang tersebut di lapisan yang berbeda. Gelombang Kelvin dan gelombang Rossby- Gravity memiliki kecepatan fasa yang lebih rendah di lapisan troposfer akibat terkopel dengan konveksi. Variasi gelombang Kelvin dan gelombang Rossby- Gravity di lapisan troposfer tidak dipengaruhi secara signifikan oleh perbedaan fase QBO. Hasil ini konsisten dengan teori bahwa variasi gelombang ekuator di lapisan troposfer dikendalikan oleh proses konveksi.
