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: Potensible: Platform for Student Self-Qualification Enhancement
Abstrak: Indonesia sedang mengalami fenomena bonus demografi dimana mayoritas penduduknya masuk ke dalam usia Generasi Z. Fenomena ini bisa menjadi bencana serius jika Generasi Z tidak melakukan persiapan dengan meningkatkan kualifikasi diri sedini mungkin. Potensible hadir sebagai platform yang mewadahi upaya peningkatan kualifikasi diri mahasiswa berbasis daring yang berfokus pada layanan berbagi konten, diskusi, dan penyelenggaraan kegiatan peningkatan kualifikasi diri. Penelitian ini bertujuan untuk mengidentifikasi permasalahan yang dihadapi mahasiswa saat melakukan peningkatan kualifikasi diri, merancang model bisnis yang tepat untuk platform, dan merancang prototype yang tepat untuk pengguna. Metode penelitian ini menggunakan design thinking dengan bantuan lean canvas. Hasil penelitian berupa minimum viable product dari platform yang berfokus pada layanan berbagi konten, diskusi, dan penyelenggaraan kegiatan peningkatan kualifikasi diri mahasiswa. Selain itu, platform Potensible dilengkapi dengan fitur homepage, post, pesan, kategori, event, ruangku, perpustakaan, favorite, dan laporkan yang sudah melalui pengujian dari pengguna potensial., Indonesia is experiencing a demographic bonus phenomenon where the majority of its population falls into the Generation Z age group. This phenomenon could lead to a serious disaster if Generation Z does not prepare themselves by enhancing their qualifications as early as possible. Potensible is present as an online-based platform that accommodates efforts to enhance the qualifications of students by focusing on services such as content sharing, discussions, and organizing self-qualification enhancement activities. This research aims to identify the issues faced by students when enhancing their qualifications, design the appropriate business model for the platform, and create the suitable prototype for the users. This research method utilizes design thinking with the assistance of lean canvas. The result of research is a minimum viable product from a platform that focusing on content sharing services, discussions, and organizing activities to improve students' qualifications. In addition, the Potensible platform is equipped with features such as homepage, posts, messages, categories, events, my space, library, favorites, and reporting, all of which have undergone testing by potential users.

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.
