The process of learning physics at various levels of education is still faced with several difficulties, especially the use of interactive multimedia which is still lacking so that educators are required to innovate to develop interactive multimedia to increase interest in learning and student learning outcomes. This research is a development research that aims to produce interactive multimedia based on problem based learning that is valid, effective, and practical to improve student learning outcomes on parabolic motion material. The research development model used in this study is a 4D (four D) model consisting of define, design, develop and disseminate. The instruments in this development research consist of interactive multimedia, syllabus, lesson plans, LKPD, test instruments. The data collection techniques used in this study were expert validation, limited trials and student responses. The results showed that interactive multimedia had an average score of 3.12 with a very good category, the syllabus had a score of 78.08% with a very valid category, lesson plans had a score of 73.66% with a fairly valid category, LKPD had a score of 75.50% with a very valid category and the test instrument has a score of 77.60% with a very valid category. Interactive multimedia based on problem based learning is effectively used with an average score of 3.04 with a very good category and is effectively used because there is an increase in learning outcomes with an N-gain value of 0.49 having a medium category. Interactive multimedia based on problem based learning on parabolic motion material is valid, practical, and effectively used in learning so that it is suitable for use in the learning process and proven to improve students' cognitive learning outcomes

Corona Virus (Covid-19) is a new type of virus that is transmitted from human to human through the mouth, nose and eyes. This virus attacks the respiratory system which can lead to death. This virus makes the world restless, because it is a new type of virus, so many parties do not know and do not understand how to deal with it. One thing that can be done to reduce the risk of being exposed to Covid-19 is to be disciplined in implementing health protocols. Health protocols are only limited to efforts to protect themselves from patient droplets, but do not provide full protection. SMAN 2 Mataram is one of the schools with 1685 students and 36 study groups. The large number of students and groups makes SMAN 2 Mataram vulnerable to Covid-19 transmission. There is no other choice, except to prepare students as early as possible to have awareness in mitigating the Covid-19 disaster at school. One of the efforts made is literacy education for the Covid-19 disaster mitigation. Implementation of Covid-19 disaster mitigation literacy education through Covid-19 disaster mitigation learning with the Covid-19 disaster mitigation literacy learning model. The research was conducted in class X MIPA1 SMAN 2 Mataram which resulted in students' awareness of the Covid-19 disaster mitigation in the form of inadequate knowledge and application of health protocols, even though they received sufficient information and knowledge about Covid-19. The role of the school in the form of a task force must be optimized to control students in implementing health protocols so that students feel safe when doing activities at school.

This study aims to improve the competence of prospective teacher students through the 2nd Batch Teaching Campus Program in 2021 at SMPN 19 Mataram. This activity was carried out at SMPN 19 Mataram with a total of 8 students from 5 study programs at FKIP University of Mataram. The activity was carried out for 5 months, with a total implementation time of 20 weeks starting from August to December 2021. This type of research is quantitative research. Data on improving the competence of prospective teacher students was obtained from a questionnaire with an assessment using a scale of 4. The number of questions in the questionnaire was 25. The competency criteria consisted of four categories, namely Very good (A), Good (B), Enough (C), and Poor (K). The increase in student competence from week 1 to week 20 is calculated using N-gain. The average value of student teacher competency is 83.7, which is in the Good (B) criteria. The N-gain value obtained is 70.7 which is in the high criteria. Thus, the competence of prospective teacher students will increase through the 2nd Batch Teaching Campus Program in 2021 at SMPN 19 Mataram.

This study aimed to determining the influence of students in understanding the concept of learning science in the classroom. The research subjects were students of class VIII at SMPN 3 Selong, namely class VIII A and class VIII B, with the data retrieval process using a written test of 5 items of description. The average value obtained in the control class is 65.48 while the experimental class is 85.48 with a difference of 20 points. For the hypothesis value t_hitung = 2.042 while t_tabel = 1.079 from the results of the calculation of the hypothesis test results of learning science students obtained t_hitung > t_tabel =, then the hypothesis alternative (Ha) is accepted. So it can be concluded that there is an influence in the application of the Problem Base Learning model in science learning at SMP 3 Selong

This study aims to see the effectiveness of COVID-19 disaster mitigation literacy education on students' knowledge about the spread of the COVID-19 virus, the use of masks, washing hands and maintaining a distance known as health protocols. This study also revealed the response of students to literacy education for the COVID-19 disaster in schools. The research was carried out in class X MIPA 1 SMAN 2 Mataram with Define, Design, Develop, and Desseminate (4D) designs. The results of the study found that literacy education for COVID-19 disaster mitigation was effective in increasing students' knowledge about the spread of the COVID-19 virus and the application of health protocols in schools in the normal era of life. Students also gave a positive response to the COVID-19 disaster mitigation literacy education in schools.

This study aims to describe student responses to local wisdom-based lectures in the High School Physics Studies course. This type of research is descriptive research. The research subjects were 27 5th semester students at one of the universities in the city of Mataram. The research was carried out from 18 August 2021 to 27 October 2021 with a total of 10 meetings. Lectures are conducted online through the Learning Management System (LMS). The research data was obtained by providing response questionnaires to students in the form of a google form at the end of the lecture. Student responses are said to be positive towards local wisdom-based lectures in terms of 4 aspects, namely happy, new, enthusiastic, and interested, which is at least 75%. Each aspect has 5 components that are assessed, namely lecture material, LMS discussion forums, student learning methods, lecturers' teaching methods, and assessment in the form of assignments. The results showed that 96% of students said they were happy, 78% of students said they were new, 89% of students said they were enthusiastic, and 91% of students said they were interested in lectures based on local wisdom. Thus, students expressed a positive response to local wisdom-based lectures on each component of the assessment.

This research was conducted to complete the teaching materials, namely the worksheets used by teachers. This research is also based on the lack of use of student worksheets in SMA Negeri 5 Palangka Raya. Teachers often use textbooks and modules in the learning process rather than using student worksheets. The purpose of this study was to determine the needs of students for the use of STEM-based student worksheets in class XI on dynamic fluid material. The research instrument used was a questionnaire distributed to students via google form. Based on the results of the needs analysis, 74.1% of students stated that physics is difficult to learn and understand, because it uses a lot of formulas. The online system is the main reason students have difficulty understanding physics material. Teaching materials that are often used by teachers in learning physics are textbooks. Student modules and worksheets are used very rarely and have a fairly low percentage of 33.3% and 25.9%, respectively. Therefore, it is necessary to develop STEM-based worksheets on dynamic fluid materials.
