Judul: Isolasi polisakarida Mannan dari bungkil inti sawit sebagai oral adjuvan vaksin avian influenza pada ayam dan itik:
Abstrak: Bungkil Inti Sawit (BIS) merupakan hasil ikutan dari industri pengolahan minyak inti sawit yang ketersediaanya di Indonesia cukup tinggi. Penggunaan BIS dalam pakan unggas perlu dibatasi, yang disebabkan tingginya kandungan polisakarida bukan pati (PBP) yang didominasi oleh ikatan β-mannan. Namun mempunyai fungsi lain khususnya dapat meningkatkan respon kekebalan dan kemampuannya menghambat beberapa mikroorganime patogen yang merugikan ternak. Tujuan penelitian ini adalah untuk mengkaji profil polisakarida dari BIS dan menguji kemampuan polisakarida mannan (PM) sebagai oral adjuvan vaksin Avian Influenza (AI) untuk meningkatkan respon kekebalan tubuh pada ayam dan itik.

Judul: Evaluation mannan of palm kernel cake in ration on the performance  of broiler chicken under heat stress
Abstrak: Penggunaan antibiotik growth promoters (AGP) dibatasi di industri perunggasan, karena mempunyai beberapa efek negatif yaitu meninggalkan residu pada produk akhir unggas. Salah satu alternatif AGP adalah polisakarida yang mengandung mannan. Mannan bersifat antimikrobial dan bersifat alamiah sehingga tidak menyebabkan residu pada produk akhir unggas. Salah satu bahan yang berpotensi dijadikan sumber ikatan mannan adalah bungkil inti sawit (BIS). Kandungan mannosa dalam BIS mencapai 68,9% serta ketersediaanya terjamin di Indonesia. Penelitian ini bertujuan untuk mengevaluasi pemberian bungkil inti sawit mannan dalam ransum terhadap performans ayam broiler. Sebanyak 234 ekor ayam pedaging strain ross dibagi menjadi 18 kandang dan diberi tiga perlakuan dengan rancangan acak lengkap. Perlakuan terdiri dari P0 = ransum kontrol (mengandung 0% bungkil inti sawit mannan), P1 = ransum yang mengandung mannan bungkil inti sawit 0,25%, dan P2 = ransum yang mengandung mannan bungkil inti sawit 0,50%. Hasil penelitian menunjukkan bahwa performa ayam broiler dengan penambahan bungkil inti sawit mannan dengan kadar 0,25% dan 0,50% dapat meningkatkan pertambahan bobot badan, bobot badan akhir, dan menurunkan konversi ransum dan mortalitas ayam broiler namun tidak tidak mempengaruhi konsumsi ransum. IOFC yang dihasilkan dengan menggunakan mannan bungkil inti sawit 0,25% dalam ransum ayam broiler lebih efisien dalam menghemat biaya pakan selama pemeliharaan. Dapat disimpulkan bahwa mannan dari bungkil inti sawit berpengaruh terhadap performa ayam broiler dan IOFC.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
