This research method uses the 4D model (Defining, Designing, Developing, and Disseminating). The research participants involved were 30 Javanese students from XI class (12 male students called “Mas” and 18 female students called “Mba”), the average age was 16 years old. The development of a close-ended four-tier instrument is based on the students' answers to MOWEI. The analysis results obtained that MOWEI is a valid and reliable instrument to identify misconceptions. The results of the identification of misconceptions in participants found that the highest misconceptions occurred at number 10 that was 73% and the lowest misconceptions of 10% occurred at numbers 4 and 11.

This work aims to demonstrate the available opportunity in using 100 and 140 mesh powdered mango leaf (PML) waste as a filler in polypropylene (PP) composites. Composites were produced via melt blending on a twin-screw internal mixer, with a different particulate size and a weight ratio of PML. Morphology, tensile, flexural, hardness, tear, puncture, thermal, and water absorption properties of the composites were assessed after 0, 1, 7, 14, and 28 days of water immersion. We found that the smaller particle size shows a better mechanical and water absorption of the composites, but not for thermal properties. The mechanical properties decreased with increasing PML content; however, these properties did not differ considerably from pure PP and other composites with natural filler. Besides, these polypropylene/PML composites showed excellent properties i...

Burning rock coal which is a source of electricity generation, is a contributor to the effects of the ecological crisis in the world. This caused the world needs new energy sources, such as piezoelectric, etc. The manufacture of piezoelectric mats as house bells aims to show that there is alternative energy for power generation in order to reduce the use of coal in Indonesia. By reducing the use of coal, it will reduce the occurrence of an ecological crisis. The research method we used was an experiment with planning, design and implementation stages. The renewal of this project is to assemble and apply the piezoelectric directly to objects that require electrical energy by replacing the power source from the piezoelectric system, and implementing it for house bells. Piezoelectric mat is a mat that can generate electrical energy if the surface is pressed. This...

Scientific argumentation skills become important because learning occurs through the process of scientific discussion between students and teachers in the classroom. Collaborative argumentation activities will help the students explore the relationship between ideas, change student conceptions, find evidence for claims so that a whole conceptual understanding formed. In fact, the application of the argumentation activity is rarely be used in science courses. Based on the questionnaires that had been given to eight Junior High School teachers in the province of Bengkulu related to science learning problems, the result was that students' argumentation skill is still very low compared with the other skills. The low ability of students' scientific argumentation might be caused by demonstration method applied and dominated by teachers in the classroom due to the lack of availability o...
