Judul: Pengembangan Permainan Edukasi Zimba Berbasis Mobile menggunakan Scolastici-Nolte Guidelines
Abstrak: Anak adalah masa depan bangsa. Oleh sebab itu diperlukan pengetahuan gizi sejak dini bagi anak agar dapat mengetahui dan memahami komposisi makanan yang beragam, bergizi, seimbang, dan aman. Permainan edukasi gizi seimbang dapat menjadi salah satu bentuk pengenalan komposisi makanan yang beragam, bergizi, seimbang, dan aman pada anak-anak. Penelitian ini berfokus pada pengembangan mobile game Zimba menggunakan Scolastici-Nolte guidelines dipadukan dengan metode cognitive walktrough pada bagian test and iterate tahap interface design for mobile games. Dari hasil yang didapat, hanya satu dari empat anak yang menghabiskan waktu penyelesaian tugas di atas rata-rata. Sedangkan berdasarkan jumlah kesalahan dalam satu tahap permainan maksimal terdapat tiga kali kesalahan dan minimum tidak ada kesalahan. Anak dapat menggunakan prototype game Zimba dengan mudah dan menyenangkan.

Judul: Pengembangan Guidelines Evaluasi Usability Permainan Mobile Edukasi Indonesia
Abstrak: Mobile games dan permainan komputer saat ini telah menjadi salah satu unsur yang mempengaruhi cara berpikir anak. Permainan edukasi mobile menjadi salah satu media pembelajaran bagi anak karena mempunyai unsur-unsur pendidikan yang dapat meningkatkan kreativitas serta mendukung pengembangan berpikir kritis pada anak. Sebagian besar pemain games lebih memilih memainkan permainan yang hanya bersifat sebagai sarana hiburan saja. Membuat sebuah permainan edukasi dibutuhkan sebuah acuan atau model sebagai tolok ukur dalam menentukan fungsi-fungsi utama dalam sebuah permainan. Penelitian ini melakukan pengembangan guidelines evaluasi usability untuk permainan edukasi berbasis playability heuristic dan mobile game based learning (mGBL) yang selanjutnya dievaluasikan pada 9 permainan edukasi terpilih. Dari hasil penelitian, teridentifikasi poin-poin evaluasi dari penguji terpilih yang memiliki persentase game usability heuristic sebesar 67%, mobility heuristic sebesar 81%, gameplay heuristic sebesar 41%, dan learning content sebesar 92%. Hasil evaluasi user memiliki persentase game usability heuristic sebesar 80%, mobility heuristic sebesar 81%, gameplay heuristic sebesar 53%, dan learning content sebesar 94%. Perbedaan poin-poin evaluasi yang didapat dipengaruhi oleh perbedaan usia dari kedua kelompok evaluator.

Judul: Characteristic of Overshooting Top (OT) Based on  Himawari  8  Satellite  as  a  Convective  Cloud  Feature  that  Generates  Extreme Weather in the Java Island Region
Abstrak: Overshooting Top (OT) is a feature at the top of a convective cloud that is associated with extreme weather. Research on OT in tropical Indonesia is still very limited. The existence of geostationary satellites with wide area coverage and fast frequency observations is useful for observing the fast dynamics of the OT life cycle. Therefore, this study intends to analyze the relationship between OT and extreme weather, updraft and thermodynamic conditions of OT when extreme weather occurs, the best objective method for detecting OT in the day time and night time, and the spatiotemporal distribution of OT in the tropical region of Java Island during the 2018-2021 period. Based on visual analysis using visible channel and Himawari 8 sandwich products, 87% of extreme weather events in Java were accompanied by the appearance of OT. It indicates that the presence of the OT pattern is a convection cloud pattern or feature that is closely related to extreme weather events for the Java Island region. The existence of a time lag between the appearance of OT and extreme weather events on Java Island indicates that the OT of convection cloud can be used as a precursor or nowcasting for the appearance of extreme weather. Most of the convective cloud OT features during extreme weather events on Java Island have altitude that were only able to exceed the altitude of the equilibrium level and few were able to exceed the tropopause level of 9 km – 16 km. The difference in atmospheric conditions during extreme weather events on Java Island, which is in the tropics and subtropics, is a strong and unstable convective energy condition characterized by a larger CAPE, as well as unstable KI, LI, SI and TTI values. It is offset by kinematic factors in the form of a weak vertical wind shear (bulk wind shear 0-6 km) and a higher freezing point height. The difference between extreme weather events in the Java Island region and other tropical regions compared to subtropical regions is the strong updraft speed of convection clouds. The IRW Texture COMB algorithm based on the IRW-Texture Gradient modification and the COMB algorithm shows a significant increase in quality for detecting OT and non-OT pixels in Java. Rainy days with rainfall > 50 mm/day are very common in areas with an altitude of > 500 m. On the other hand, the level of convection activity which is indicated by the presence of OT and lightning is significantly reduced in this area. OT of convective clouds appear more frequently during the DJF season and less frequently during the JJA season. OT often appears during the day time and rarely at night time. Most OTs appear in the central part, away from the south and north coasts of Java Island during the day, while OTs that appear near the south and north coasts of Java Island can appear in the morning or afternoon.
