21st-century education requires creative students who can master science and technology, art, and culture through the development of education. Innovation in physics learning is needed to increase the creativity of students in the 21st century. One of the efforts to support the creativity of students is through the integration of STEM learning combined with local wisdom. Ethno-STEM is an educational approach that is appropriate to be applied in the 21st century. The integration of STEM and Ethnoscience approaches can make physics learning more meaningful. The research was conducted to determine the use of Ethno-STEM-based teaching materials in increasing the creativity of students in physics learning with the subject of dynamic fluid. The research method used is the pre-experimental method with a one-group pre-test and post-test design. Data were collected through observation sheets and creativity test instruments. Analysis of research data obtained by calculating N-Gain, normality test, and paired t-test. The results of the N-Gain calculation obtained a value of 0.50 in the medium category. The results of the paired t-test obtained a significant difference between the pre-test and post-test. The results of the research indicate that using Ethno-STEM-based teaching materials can increase students' creativity in learning physics.

This research aims to develop a web-based recitation program with multiple representations of kinematics material and to determine the feasibility of the product being developed. The recitation program aims to make it easier for students to deepen kinematics material outside lecture hours. This study uses the Research and Development (R&D) method with a 4D model development design consisting of 4 stages, namely defining, designing, developing, and disseminating. The data obtained from this research are quantitative data obtained from questionnaire assessment scores on the validation sheet and practicality test sheets based on the Likert scale, as well as qualitative data obtained from suggestions/comments from validators and students. The validity test was carried out by 1 physics lecturer at the State University of Malang and 2 physics lecturers outside UM, while the practicality test was carried out on 60 UM physics students who had obtained kinematics material. The data analysis technique used is the descriptive qualitative analysis and descriptive statistical analysis. In this research, the results of the data analysis of the program display validation were 87.67% and the results of the content validation data analysis were 93.31% with the valid category. While the practicality test obtained a percentage of 84.33% with practical criteria. The validation results and practicality test results show that the products developed are valid and suitable for use by students as independent teaching materials.

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. The hope of this research is that it can be a reference in reviewing the application of PBL in learning in Indonesia.

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.

The still low understanding of the concept of students in vocational schools in learning physics, due to the lack of innovative learning, so it needs innovation such as a reciprocal teaching model that implements four independent understanding strategies, namely summarizing the material, compiling questions, explaining, and predicting. The purpose of this research was to determine the improve in understanding of students' concepts in the class applying the reciprocal teaching model with conventional classes at Vocational High School (SMK) Abdurrab Pekanbaru. The population in this research were 130 students spread over five classes and samples were taken by simple random sampling, so that 2 classes of samples were obtained with 52 students. The research instrument was in the form of concept comprehension test questions consisting of pretest and posttest. The Test in the form of multiple choice reasoned with 4 choices totaling 15 items. The instruments are arranged according to the category of understanding the concepts of translation, interpretation, and extrapolation. Data collection techniques in the form of scores on the concept understanding results obtained from the pretest and posttest scores. The data is processed by descriptive analysis. The results showed that students of class X SMK Abdurrab Pekanbaru in optical material learning, had a difference in increased understanding of concepts. The average score of concept understanding after the implementation of learning in the experimental class was 82.44 with a high category, while the control class was 59.68 with a low category.

Andaliman has the Latin name Zanthoxylum acanthopodium and is a family of Rutaceae. Andaliman is anative spice from North Sumatra called the golden spicy from North Sumatra. Andaliman farmers inParsoburan Village, Toba Samosir said that one of the problems in andaliman production is the number ofAndaliman fruits that are still not effective, even most of the Andaliman fruit becomes rotten. The design ofAndaliman perfume machine has been carried out which aims to increase the usefulness of Andalimanthrough the manufacture of andaliman perfume as well as to increase the economic value of Andaliman. Themethod used is by designing a perfume machine and making an official perfume machine, testing the machineand using a perfume machine. Making perfume machines and testing perfume machines was carried out atthe UNIMED Mechanical Engineering Workshop and the implementation of machine use activities wascarried out in Parsoburan, Toba Samosir Regency. The results obtained from the andaliman smoothingmachine were processed as 2 kg of perfume in a single smoothing process, for the heating stage mixed with300 mL ethanol and the results of the perfume ± 20 mL which will be mixed with alcohol according to thestrong aroma made.
