The purpose of this study was to find out how effective online learning media is in improving high school students' physics learning outcomes during a pandemic. There are regulations from the Ministry of Education and culture regarding the implementation of education during the Covid-19 pandemic which requires distance learning using online learning media. The use of online learning media by developing technology can be a new innovation to further increase the effectiveness of online learning, including in physics subjects. The method used is a literature research and library research using learning literature in the form of scientific articles in journals and books that reveal the effectiveness of online learning media. The results of the research show that digital-based online learning media is quite effective in improving high school students' learning outcomes in physics subjects. With these results, it is hoped that educators (teachers and lecturers) or educational researchers can develop and innovate learning media that are more effective and efficient in improving student learning outcomes, especially in physics subjects

Pandemi Covid-19 memberikan dampak negative pada proses pembelajaran. Penggunaan teknologi pada pembelajaran online tidak selamanya berdampak baik. Pembelajaran online lebih banyak memberikan beban tugas dan pekerjaan rumah. Hal ini turut menurunkan motivasi dan kemauan belajar peserta didik. Salah satu daerah yang anak-anaknya mengalami penurunan motivasi belajar adalah Desa Badrain. Model pembelajaran yang dapat meningkatkan motivasi belajar peserta didik adalah model pembelajaran berbasis proyek (PjBL). Model ini  memberikan proyek kepada peserta didik. PjBL memberikan kesempatan kepada peserta didik untuk berinteraksi dan berpartisiapasi lebih jauh dalam pembelajaran yang dikemas dalam bentuk pembelajaran berkelompok, sehingga mampu meningkatkan motivasi belajar pasca pandemi. Maka dari itu, HIMAFIS FKIP Universitas Mataram melaksanakan pengabdian masyarakat dengan menerapkan pembelajaran berbasis proyek untuk meningkatkan motivasi belajar anak-anak di Desa Badrain. Kegiatan pengabdian terdiri atas tiga fase yaitu fase orientasi, fase pembelajaran dan fase penutupan. Kegiatan pengabdian kepada masyarakat ini cukup berhasil. Keberhasilan dapat dilihat dari motivasi, rasa ingin tahu dan interaksi peserta didik meningkat ditandai dengan banyaknya peserta didik yang berpartisipasi dan mampu menjelaskan kembali hasil proyek yang dibuat dalam kelompok pada pembelajaran berbasis proyek

This study aims to synthesize barium M-hexaferite using the coprecipitation method with Zn doping based on natural iron sand at the Tebing Beach of North Lombok as a microwave absorbent material. This study used 3 variations of doping concentration (x), namely x = 0.000; 0.400; and 0.800. In addition, variations in the calcination temperature were also carried out, namely 400°C and 1100°C. After the calcination stage, the sample is ground to obtain smaller or nano-sized particles. The results showed that the sample has a brick red color for a temperature of 400°C and black for a temperature of 1100°C. This shows that the higher the calcination temperature, the darker the color of the sample.

Graphene is considered as the initial laboratory-made 2D material which initiated a new revolution in the field of materials science. Since its discovery, lots of researchers have discovered various properties and tested it for many potential applications. The present report discusses a brief overview of graphene, mainly concentrating on the structure, synthesis, and applications of graphene. The mechanical exfoliation and CVD techniques for the synthesis of graphene. Some of the applications of graphene in the field of flexible electronics, sensing, and photovoltaic are reviewed in this report

This activity aims to increase children's learning motivation during the pandemic through the play learning method. In addition, the Physics Education Student Association also carries out social activities such as community service and learning the Koran which is carried out at several points such as the Babussalam mosque which is located in the Tojong-Ojong Sombek hamlet, Selebung Village. This activity also aims to analyze the potential of play learning methods in increasing children's interest in learning in the midst of a pandemic and provide training on physics concepts in water rocket games.
