Learning during the COVID-19 pandemic has an impact on students’ learning outcomes. Observation results in SMP 2 Dawe Kudus showed that students’ learning outcomes in science subjects are still low. This school was chosen because of the location of the school in remote areas which resulted in not optimal use of digital devices for assessment in learning.  The purpose of this study is to analyze the characteristics, feasibility, and profile of learning outcomes using digital science scrapbooks as authentic assessment to measure the learning outcomes of junior high school students on the theme of Additives and Addictive Substances. This study used a Research and Development (RD) design with ADDIE model. The science digital scrapbook as an authentic assessment developed in this study was declared feasible to use based on the assessment of material experts and evaluations. The reliability coefficient values obtained from small-scale tests for essay questions, attitude assessment instruments, and skills assessment instruments were obtained 0.62; 0.84; and 0.38. Students’ learning outcomes measured using a digital science scrapbook as an authentic assessment showed 83.3% of students were complete in the realm of knowledge, 100% completed in the realm of attitudes, and 100% completed in the realm of skills. The conclusion of this study is science digital scrapbook as an authentic assessment developed in this study was feasible to be used to measure the learning outcomes of junior high school students on additives and addictive substances concept

The purpose of this community service is to provide training on AR (Augmented Reality) PBL (Problem Based Learning) model to science teachers in Semarang, Indonesia. The debriefing and training were carried out through webinars in the form of AR training on the PBL model in online science learning. The method used in this community service activity is the presentation of material by the community service team, discussions in the form of questions and answers, training assistance, demonstrations and direct practice via Zoom Meetings using the AR PBL model. The result of this community service activity can increase understanding of the use of AR PBL model. Participants had a positive response to the material, presentation, language, and practice aspects that were facilitated by the community service team. Based on the grouping of the results of the responses of participants to the questionnaires that have been given, the average response of participants to the implementation of the training is 37.22. The score implies that the participants stated that the activity had been going well.

In the present day, it is anticipated that students possess the ability to effectively utilize digital technology to process information and address contextual problems. One possible course of action would be to develop a STEM-based Science Digital Worksheet on the Material of Object Motion. The STEM aims to facilitate the application of contextual problem-solving techniques through the utilization of students' literacy and numeracy skills. The scope of this study encompasses the field of research and development, commonly referred to as R&D. The R&D model employed ADDIE. One of the stages defined in this model is the developmental stage, which is intended to assess and evaluate the product through expert validation tests. The validators comprised of educators in the field of Integrated Science at FMIPA Semarang State University, ICT experts at SMA Negeri 1 Kudus, and science teachers at SMP 2 Dawe Kudus. The obtained media validation results from three experts yielded a value of 95%, while material experts obtained 96.67%. As a result, both were classified as highly feasible. It can be concluded that the Science Digital Worksheet is appropriate for use in learning activities
