Judul: Potential of Agarwood (Gyrinops versteegii Gilg.) as Analgesic and Endurance Stimulator in Male Mice (Mus musculus)
Abstrak: Indonesia merupakan salah satu negara yang memiliki keragaman dalam flora dan faunanya. Hal ini ditambah dengan unsur tradisional yang masih kental di Indonesia menyebabkan pemanfaatan tanaman tradisional sebagai bahan obat masih marak digunakan. Pohon gaharu merupakan salah satu tanaman yang banyak digunakan batangnya untuk wewangian, dupa, dan obat tradisional. Akan tetapi, pemanfaatan bagian daun gaharu masih belum banyak digunakan meskipun sudah terbukti mengandung banyak senyawa berkhasiat. Penelitian ini bertujuan untuk menguji potensi daun gaharu sebagai analgesik dan stimulator stamina. Pengujian analgesik dilakukan dengan metode tail immersion test, sedangkan stimulator stamina menggunakan metode ketahanan berenang. Penelitian ini menggunakan 20 ekor mencit jantan yang diberi infusa daun gaharu dengan berbagai dosis, yaitu 0, 1, 2, dan 4 g/kg BB, dengan kelompok 0 menjadi kelompok kontrol. Setiap kelompok perlakuan terdiri atas 5 ekor mencit. Pemberian infusa daun gaharu dilakukan secara per oral dalam tiga kali pengulangan dengan selang selama satu hari. Data yang diperoleh dari hasil penelitian dianalisis secara statistik menggunakan analysis of variance (ANOVA) one way dilanjutkan dengan uji Tukey. Hasil penelitian menunjukkan dosis 4 g/kg BB infusa daun gaharu menghasilkan efek analgesik serta stimulan yang lebih efektif dibandingkan dengan dosis lainnya. Kesimpulan penelitian ini adalah bahwa infusa daun gaharu dapat digunakan sebagai analgesik dan stimulator stamina alami.

Judul: Effectiveness of Cinnamon (Cinnamomum burmanii) Infusion as an Analgesic Effects and Stamina Enhancer in Male Mice (Mus musculus)
Abstrak: Kayu manis merupakan tanaman herbal yang memiliki beragam khasiat bagi kesehatan. Penelitian ini bertujuan mempelajari efektivitas infusa kayu manis sebagai analgesik dan peningkat stamina tubuh hewan. Penelitian ini menggunakan 20 ekor mencit jantan galur Deutschland Denken Yoken yang dikelompokkan menjadi 4 kelompok perlakuan dengan tiap kelompok terdiri atas 5 ekor mencit. Kelompok perlakuan dibagi menjadi kelompok mencit kontrol dan mencit perlakuan yang diberi infusa kayu manis dengan dosis 1, 2, dan 4 g/kg BB. Perlakuan dilakukan secara peroral dengan 3 kali ulangan dengan selang waktu satu hari. Pengujian pada uji analgesik dengan metode tail immersion flick test dan uji stamina dengan metode forced swim test. Data yang diperoleh dianalisis menggunakan one way analysis of variance (ANOVA) yang dilanjutkan dengan uji Tukey. Hasil penelitian menunjukkan bahwa pemberian infusa kayu manis pada mencit jantan mampu memberikan efek analgesik pada dosis 4 g/kg BB dan mampu meningkatkan stamina pada dosis 2 dan 4 g/kg BB. Kesimpulan penelitian ini ialah kayu manis memiliki potensi sebagai analgesik dan peningkat stamina., Cinnamon is a herbal plant that has various health benefits. This research aims to study the effectiveness of cinnamon infusion on analgesic effects and to increase stamina for animals body. This study used 20 male mice of the Deutschland Denken Yoken strain which were grouped into 4 treatment groups with each group consisting of 5 mice. The treatment group was divided into control mice and treatment mice that were given cinnamon infusion at doses of 1, 2, and 4 g/kg BW. The treatment was carried out peroral with 3 repetitions with an interval of one day. The analgesic test uses the tail immersion flick test and the stamina test uses the forced swim test. The data obtained were analyzed using one way analysis of variance (ANOVA) followed by the Tukey test. The results of the study showed administrating cinnamon infusion to male mice was able to provide an analgesic effect at a dose of 4 g/kg BW and was able to increase stamina at a dose of 2 and 4 g/kg BW. The conclusion of this research is that cinnamon has the potential as an analgesic and stamina enhancer.

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.
