Learning management system (LMS) is a learning solution in the midst of the Covid-19 pandemic situation. In addition, the LMS learning media is also a medium that supports education in the demands of technological development 4.0. LMS is an online-based application designed to assist the learning process with creative and innovative material designs. LMS has many types, this time the researcher uses google classroom as a learning medium. The purpose of this research was to profile the application of physics learning using google classroom media at SMK Bodronoyo Jiwan, Madiun. The sample used was class X students majoring in APHP at SMK Bodronoyo Jiwan, Madiun. This research method is a descriptive qualitative data analysis model using the Technology Acceptance Model (TAM). The results of this research explain that the learning applied in class X APHP using google classroom gets a very good response. Obtaining this data states that on average students respond very satisfied, this is explained in 5 aspects, namely ease of access, perceived usefulness, communication and interaction, delivery of instructions, and student satisfaction on the application of Google Classroom in teaching and learning activities.

The by-product of pepper production in Bangka Belitung is the waste of pepper skin. This waste tends to be untapped and thrown away so that it can disrupt the environmental ecosystem. One of the efforts to utilize pepper skin waste is processing it into activated carbon as the base material for supercapacitor electrodes. The initial stage of the synthesis was carried out by a pre-carbonization process on a sample of dry and clean pepper peel waste. Furthermore, the sample is chemically activated using a chemical activator and also physical activation at a temperature of 700ºC in N2 gas flow conditions. The activated carbon resulting from the activation is then molded into electrode plates in the form of pellets with a diameter of 1 cm. The electrode plates were characterized using a scanning electron microscope-energy dispersive x-ray (SEM-EDX) to determine morphology and cyclic voltammetry (CV) to determine the specific capacitance value. SEM test results show that the electrode sample has porous morphology and CV results show that the sample activated using the KOH activator has a specific capacitance value of 15.20 F/g. These results indicate that the activated carbon synthesized from the waste of pepper peel can be used as a supercapacitor electrode material and also a solution for overcoming the negative effects of pepper skin waste.

Outdoor Learning-based physics student worksheets are task sheets that must be done by students that contain instructions for activities that will be used outside the classroom. This research aims to develop a valid physics worksheet based on outdoor learning on the material of straight motion for class X SMA. The type of research used is Research and Development (R&D) based research with a 4-D model design consisting of 4 stages of development, namely Define, Design, Develop, and Disseminate. Validation is carried out at the development stage by 3 validators who are experts and experienced in their fields and have experience. The instrument of this research is an assessment sheet in the form of a checklist. This research uses two types of data collected, namely quantitative data obtained from the score of the validation sheet assessed by the validator and student responses, while the qualitative data is in the form of criticism and suggestions from the validator on the product developed and a description of the implementation of product trials. Data analysis used descriptive analysis by calculating the index of each indicator used to determine the validity of the developed student worksheets. The results of this research provide an outdoor learning-based physics worksheet product which was developed on straight motion material which was declared valid from the presentation, linguistic, and graphic aspect with high and very high categories, so it was feasible to use in learning to support the teaching and learning process so that it became better.

The purpose of this research was to determine the effect of problem based learning on the understanding of high school students' concepts. The meta-analysis, which was conducted by summarizing several research articles on the effect of problem based learning on physics learning, was also carried out on students' understanding of concepts in physics learning obtained from articles published between 2015 and 2020. In particular, this research obtained an effect size (ES) =1.005 (high category). The research was conducted by grouping 20 articles into two categories, namely based on the material unit, and based on the approach used. Based on the material unit, there are 15 articles that were analyzed by effect size (ES) and obtained an effect of 0.82 with a high category with a percentage of 54.5%. The material with the greatest influence is temperature and heat with ES = 1.78, while the grouping based on the approach used there are 5 articles that were analyzed with the results of the effect size (ES) analysis of 1.19 with a high category with a percentage of 60%. The approach that has the most influence on PBL is HOTS with ES= 3.02. From the results of this study, it can be seen that the PBL model has a significant effect on physics learning.
