Judul: Veterinary Anatomy Learning Experience with Virtual Reality Teaching Materials
Abstrak: Pembelajaran anatomi veteriner dalam studi kedokteran hewan didukung oleh kegiatan praktikum menggunakan kadaver pada laboratorium. Penggunaan kadaver sebagai materi pembelajaran menjadi standar emas untuk meningkatkan pemahaman mahasiswa. Perkembangan teknologi termasuk teknologi realitas maya menyediakan pilihan alternatif sebagai media pembelajaran. Penggunaan teknologi virtual sekaligus mengurangi kelemahan dalam penggunaan kadaver. Metode ini juga dapat membawa pengguna untuk merasakan pengalaman di dalam dunia maya dan dapat mempelajari bahan materi secara mandiri di mana saja dan kapan saja. Penelitian ini mengembangkan prototipe sistem pembelajaran dengan osteologi tulang kuda dalam teknologi virtual dengan akses virtual reality yang terintegrasi dalam situs dengan metode embed sehingga pengguna dapat mengakses situs melalui berbagai perangkat seperti komputer, ponsel, dan headset VR. Prototipe berhasil lulus uji pengalaman pengguna dengan basis metode UEQ dengan hasil dapat diterima sebagai media alternatif pembelajaran anatomi veteriner pada daya tarik, kualitas pragmatis yaitu efisiensi, kejelasan, ketepatan, juga dari kualitas hedonis yaitu stimulasi dan kebaruan, The learning of veterinary anatomy in veterinary education is generally supported by practical exercises on animal cadavers performed in a specific laboratory. The use of cadavers as teaching materials is a gold method standard to improve students understanding. On the other hand, the development of technology, including virtual reality technology, provides an alternative to learning methods. By using virtual technology, the disadvantages of using animal cadavers are compensated at the same time. This method can also make users feel like they are in a virtual world and enable independent learning at any place and time. In this research, we developed a prototype learning system using VR technology applied to the skeletal model of a horse bone. To enable easy access, the VR is integrated into the access channel on the website so that users can access it through various hardware devices such as computers, smartphones, and VR glasses. In this research, we found that the prototype successfully passed the user experience test based on the UEQ method and therefore can be accepted as an alternative medium for learning veterinary anatomy in terms of attractiveness, pragmatic quality such as efficiency, perspicuity, dependability, also from hedonic quality such as stimulation and novelty

Judul: Pengembangan Teknologi Virtual Pembelajaran Anatomi Veteriner (Studi Kasus: Anatomi Tulang Kuda)
Abstrak: Pembelajaran anatomi veteriner dalam pendidikan kedokteran hewan umumnya didukung dengan kegiatan praktikum menggunakan kadaver hewan dan dilakukan di laboratorium khusus. Penggunaan hewan atau kadaver hewan sebagai alat praktik pendidikan sangat membantu pemahaman mahasiswa terhadap materi pembelajaran dan dianggap sebagai metode terbaik, akan tetapi metode tersebut masih terus dievaluasi karena masalah etis. Pada tahun 2020, kejadian pandemi Covid19 yang melanda dunia menyebabkan kebutuhan akan pembelajaran anatomi veteriner secara jarak jauh perlu diteliti dan dikembangkan. Perkembangan teknologi memberikan alternatif pengembangan metode pembelajaran salah satunya dengan teknologi virtual berbasis Virtual Reality (VR). Penggunaan teknologi virtual berbasis VR sekaligus untuk mengatasi kekurangan dalam penggunaan kadaver hewan dan pemenuhan kaidah kesejahteraan hewan (animal welfare). Metode tersebut juga mampu membawa pengguna merasakan pengalaman berada di dunia virtual dan memungkinkan pembelajaran mandiri dilakukan di segala tempat. Penelitian ini bertujuan mengembangkan sistem berdasarkan metodologi Prototype dengan keluaran berupa sistem perangkat ajar menggunakan teknologi VR yang akan diterapkan pada model tulang kuda (Equus Caballus). Selanjutnya untuk mempermudah akses, VR akan dipadukan dengan saluran akses website melalui metode embed sehingga pengguna bisa mengakses dari berbagai perangkat keras seperti komputer, ponsel pintar dan kacamata VR. Dalam penelitian kali ini prototype sistem telah berhasil melewati pengujian fungsi melalui metode Black box dan mendapatkan nilai melebihi rata-rata dalam pengujian pengalaman pengguna menggunakan metode UEQ. Berdasarkan hasil pengujian tersebut prototype sistem bisa digunakan sebagai alternatif perangkat belajar dengan daya tarik dan kualitas yang baik.

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.
