This paper analyzes the implementation of socio-scientific issues (SSI) as an alternative in science learning. The content analysis approach is used for mapping implementation of social-scientific problems around the world and is created using the ArcGIS 10.5 program. The findings highlight how the distribution patterns of SSI implementation are dominated by argumentation and decision making in SSI research. Teacher professional development related to SSI implementation also showed positive results for planning, developing, and solving problems related to SSI instruction. This study contributes as literature in exploring the implementation of SSI in educational contexts because its integration in science teaching materials is unfamiliar.

Corn cobs briquettes are made from corn cobs that have been dried and previously mashed with a size of 20 mesh. Each treatment was printed with variations in the percentage of tapioca starch adhesive, namely 5%, 10%, and 15%. In addition to variations of the adhesive, variations in the formation pressure were also carried out to see the best composition that produced a high heating value and an appropriate combustion rate. The briquettes were then tested for calorific value and rate of combustion using a bomb calorimeter. The results showed that the calorific value and burning rate of briquettes with the percentage of adhesive composition 5%, 10%, 15%, were 21.00 kJ, 22.68 kJ, 31.08 kJ, and 12.00 gram/minute, respectively. 13.33 grams/minute, 13.50 grams/minute. The best results were obtained at 15% adhesive percentage composition with a calorific value of 31.08 kJ, and a burning rate of 13.50 gram/minute which was not significantly increased compared to other adhesive percentage compositions. Keywords: briquettes; corn cobs; calorific value; combustion rate

Computer technology presents opportunities and innovations in physics learning. Some of the concepts of physics are abstract concepts. Learning abstract concepts requires appropriate media assistance. In this research, we have developed some computer simulations to support the learning concept of mechanics. The study aimed to examine the effectiveness of computer simulation in students’ understanding of mechanics. The sample used is students from the department of physics education who took a mechanics course at University of Mataram. Data were collected using multiple-choice and essay tests and then analyzed quantitatively. Data analysis used the ANAVA test and N-gain score. The result of the research shows the influence of computer simulation on students’ understanding of the concept of mechanics. Improvement occurs in all sub-materials of mechanics. The average for the concept mastery of students in the experimental group is higher than that of the control group. Statistically, the difference in the increase in the concept mastery between the two groups did not significantly differ. The improvement in students' concept of learning using computer simulation was higher than the control group who studied conventionally.

This development research aims to produce a product in the form of an ethnophysics-based learning tool to improve prospective physics teachers' valid and effective self-regulation. The products developed are Lecture Event Units known as SAP, Student Worksheets or LKM, Teaching Materials, and test instruments. The research design used is a 4D model consisting of Defining, Designing, Developing, and Disseminating. Data collection techniques use validation sheets and evaluation tools. Device validity data was analyzed using a Likert scale. Three expert validators assess product validity. Assessment by validators with valid to very valid criteria. The effectiveness of the teaching materials developed by researchers can be determined by increasing students' self-regulation based on the results of the N-Gain test after being given a pretest and posttest. The planning indicators show that the percentage of students who were suitable/suitable before implementing the ethno-physics learning model was 42%. This indicates that more than 50% of students have self-management related to learning planning that still needs to be improved. Applying the ethno-physics learning model as a stimulus to help students manage good learning planning contributed 36%, increasing to 78%. The monitoring indicator also has the same increase in the number of students as the planning indicator, namely 36%. This can be described as more and more students being able to manage their learning by monitoring their learning process. The evaluation indicator shows the largest percentage increase in the number of students, namely 38%, while it is only 28% for strengthening. This indicates that the ethno-physics learning model has the greatest contribution to stimulating students' evaluation abilities
