Judul: “Edu Mahir”: Nonformal Education Platform Liaison between Institutions and Students
Abstrak: Orang tua dan generasi muda Indonesia memiliki kebutuhan/keinginan untuk mengembangkan minat dan bakat anak/dirinya. Namun. masih terdapat lembaga pendidikan nonformal (LPNF) yang kurang melakukan promosi yang menyebabkan terbatasnya ketersediaan informasi. Hal ini diperparah dengan adanya pandemi COVID-19 yang membatasi mobilitas fisik di luar rumah. Maka dari itu, “Edu Mahir” dirancang sebagai multisided platform yang menghubungkan LPNF dengan Peserta Didik. Penelitian ini bertujuan untuk mengidentifikasi permasalahan orang tua dan generasi muda (sisi demand) dan LPNF (sisi supply), serta merancang model bisnis “Edu Mahir” yang tepat untuk kedua sisi. Metode yang digunakan pada penelitian ini adalah design thinking dengan alat analisis berupa empathy map, lean canvas, dan UTAUT 2 untuk menguji prototype dan mendapatkan rekomendasi bagi “Edu Mahir”. Hasil penelitian ini menunjukkan bahwa kedua sisi mengalami berbagai permasalahan dalam mencari dan memasarkan LPNF, sehingga model bisnis dan prototype “Edu Mahir” dibuat khusus untuk menyelesaikan permasalahan tersebut.

Judul: Go EduWorld: Digital Platform untuk Solusi Integrasi Pelajar Persiapan Studi Luar Negeri
Abstrak: Pertumbuhan pelajar dalam melanjutkan studi luar negeri terus meningkat sebesar 62% semenjak tahun 1998. Indonesia menempati peringkat ke-22 di seluruh dunia sebagai negara yang mengirim pelajar studi ke luar negeri. Studi luar negeri memberikan banyak manfaat bagi pelajar terutama dalam menghadapi tantangan global yang penuh persaingan. Namun, pelajar ternyata menghadapi banyak masalah dalam perencanaan dan persiapan studi luar negeri. Tujuan penelitian ini mengidentifikasi masalah perencanaan dan persiapan studi luar negeri, menyusun model bisnis serta merancang prototype sesuai dengan preferensi konsumen. Penelitian ini menggunakan pendekatan customer development yang berfokus pada tahap customer discovery, dengan alat analisis Business Model Canvas. Penelitian ini menghasilkan BMC terverifikasi dan MVP aplikasi bernama Go EduWorld. Berdasarkan hasil penelitian, semua responden potensial menyatakan fitur Go EduWorld dapat menyelesaikan masalah. Namun, willingness to pay dari responden potensial untuk fitur GoScholarship tidak mencukupi sehingga digital platform Go EduWorld berisi tujuh fitur yaitu GoDoc, GoEnglish, GoConsult, Student Essentials, GoPackage, Course Finder, dan GoEvent. MVP Go EduWorld divisualisasikan dalam bentuk prototype yang diuji dan hasilnya dapat diterima menjadi solusi atas permasalahan yang ada.

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.
