Abstract

This development research aims to produce an effective video-assisted problem-based physics learning tool to improve students' problem-solving skills on elasticity material. The research design used is a 4D model consisting of defining, designing, develop and disseminating. The products developed are syllabus, Lesson Plans, Student Worksheets, videos, and problem-solving ability questions. Data collection techniques using validation sheets and problem-solving ability questions. Product validity was assessed by six validators consisting of three expert validators and three practitioner validators. Furthermore, the effectiveness was obtained from a limited trial by providing problem-solving skills questions in the form of pretest and posttest which then the results were analyzed using N-Gain. The results showed that problem-solving abilities had increased with the average N-Gain test result being 0.61 in the medium category. Students show a positive response to online learning. So, it can be concluded that video-assisted problem-based physics learning tools are effective for improving students' problem-solving skills on elasticity materials during online learning

Abstract

NTB Province is one of the areas prone to natural disasters. In 2018 there was an earthquake that destroyed infrastructure and the safety of human life. The number of casualties due to the earthquake, one of which is the lack of public knowledge about disasters. Through counseling, the increase in knowledge and capacity to reduce disaster risk in science master students at the University of Mataram. It is hoped that students as intellectual agents in the community can continue or inform their environment. Data collection methods: before and after counseling, students were given a questionnaire via google form sent via WA regarding a) disaster knowledge, b) disaster risk reduction capacity and c) disaster mitigation measures. The discussion is more devoted to earthquake disasters. Outreach was held on November 5, 2020 virtually via zoom meeting. The number of participants who took part was 45 people, consisting of 16 male students and 29 female students. The results show that it is not satisfactory, because the percentage increase in knowledge at the high level is still smaller than the percentage level at the lower level. Therefore, it is suggested that education about disaster risk capacity still needs to be disseminated.

Abstract

This study aims to examine whether or not there is an influence of the PhET-assisted problem-based learning model on student learning outcomes in Wave material. The type of research used is a quasi-experimental research design with Nonquivalent Control Group Design. The population in this study were all students in class XI MAN 1 Mataram with the sample being students in class XI MIPA 3 with a total of 31 students as the control class and students in class XI MIPA 4 with a total of 29 students as the experimental class. The test instrument used is in the form of multiple choice questions. Before the test instrument is given, the instrument is tested first, namely testing validity, reliability, difficulty level, and discriminating power. The results of the analysis showed that the average score of the physics learning outcomes of students who were taught with the PhET-assisted problem-based learning model was 79.65 and students who were taught without using PhET had an average value of 69.77. The results of testing the hypothesis using the t-test obtained a t-count of 6.45 and a t-table of 2.0017. Thus the value of t-count is greater than t-table then Ha is accepted and H0 is rejected. This means that there is an influence of the PhET-assisted problem-based learning model on student learning outcomes in class XI MAN 1 Mataram class wave material.

Abstract

The aircraft used in this study is the upper wing type which has the advantage of flight stability. This upper wing aircraft was designed by the researchers themselves with three different types of wings with a wing span of 1.35m and a fuse lag of 0.925 meters. There are four main forces that work when the plane is in the air, namely lift, thrust, air resistance and gravity. From the results of this study, it can be concluded that the heavier the aircraft unit being flown, the greater the minimum thrust required to fly the aircraft. The measurement results of the 3 aircraft weights, namely 917 grams, require a thrust of 2030 grams of force, whereas for a total aircraft weight of 1,230 grams a thrust of 2510 grams is required, and at an aircraft weight of 1495 grams a minimum thrust of 3040 grams is required. The results also show that the thrust generated is not linear with the throttle position

Abstract

Refraction of light occurs due to the difference in the speed of light in the two mediums where the speed of light in a dense medium is smaller than the speed of light in a less dense medium. One of the refraction phenomena also occurs in prism glass. Prisms help scatter incoming light from monochromatic light sources. To prove this, refraction experiments can be carried out using a prism. Where the prism used is made manually using used glass made of acrylic. The prism that is made is then filled with water on the inside and a test is carried out to determine the refraction and the value of the angle of deviation. Based on the results obtained, the refraction of the prism glass made in where a beam of light that passes through the prism is deflected from its original direction, while the angle of deviation of the rays is proportional to the angle of incidence

Abstract

This study aims to examine the effect of problem-based learning model assisted by PhET simulations on problem solving ability and mastery of physics concepts of students. This type of research is Quasi Experimental with non-equivalent control group design. The population of this study were all students of class XI IPA SMAN 4 Mataram with sampling technique using purposive sampling technique, because there were four classes XI IPA, so it was determined that class XI IPA 1 as the experimental class and class XI IPA 2 as the control class. Based on the results of the study, the average value of physics problem solving ability of students in the experimental class was 45.09, while the average value of problem-solving ability of the control class was 39.61, while the average value of concept mastery of the experimental class was 70 and the control class was 51.15. Data on problem solving ability and concept mastery of both classes are normally distributed and both are homogeneous. Data on problem solving ability and concept mastery were analyzed using the polled variance t-test at a significant level of 5% and obtained  of problem solving ability of 2.24, while concept mastery obtained  of 6.18 and obtained  of 2.00, with hypothesis testing criteria if  is greater than  then  is rejected and  is accepted. Based on the results of this study, it shows that there is an effect of problem-based learning model assisted by PhET simulations on problem solving ability and mastery of physics concepts of students.

Abstract

Natural disaster mitigation learning is inclusive education in elementary school. There for, this aims to express the responses and opinions of teachers about the implementation of the disaster mitigation learning model and to improve the ability of teachers in elementary schools. The study was conducted on three schools consist elementary schools in Mataram, Ampenan, and Sembalun in Lombok Island-West Nusa Tenggara-Indonesia. The method of research begins with a presentation of a learning model for natural disaster mitigation such as peer teaching by the research team. After that discussion with moderation technique regarding disaster mitigation learning structure applied in the previous presentation. The results of the study obtained 5 main ideas of strategies about the implementation of the natural disaster mitigation learning model, namely that 1) students must be conditioned to natural disasters in the learning process, 2) teachers must have the correct steps in providing the understanding of natural disasters and in conducting direct demonstrations so that students thoroughly understand, 3) teachers must have knowledge of earthquakes, tsunamis, landslides, floods, hurricanes and volcanoes, 4) teachers provide examples of disaster mitigation learning to students using tools such as videos, disaster mitigation tools, etc, 5) understanding risk, vulnerability, threat and capability of natural disaster. In general conclusion, teachers have to ability to use technology pedagogical and content knowledge strategies for natural disaster mitigation learning.
