Abstract

This study aims to reveal the various renewable energy sources that have the potential to be developed on the island of Java, Indonesia. Because it is cheap and easy to reach, non-renewable energy is widely used as a source of energy for people's lives. The negative side of non-renewable energy sources forces local governments to look for alternative energy sources that are more environmentally friendly. Environmentally friendly alternative energy is rarely studied, specifically on the island of Java, through literature studies. Therefore, this study used a research method: a literature study on 28 Scopus, WoS, and Sinta-indexed articles. This literature study yields the information that 10 types of renewable energy sources have the potential to be developed in Java. These renewable energy sources can be further developed using technology according to their potential in each province. Thus, this research has succeeded in linking various renewable energy sources that have the potential to be developed on the island of Java.

Abstract

This study aims to develop an instrument that measures students' attitudes toward physics ang to test its validity and reliability. This instrument was a result of a modification from the PAS Questionnaire, namely IMPAS. This research novelty is making a new instrument that solves the shortcomings in PAS Questionnaire. So, this instrument can be used by teachers and researcers in Indonesia. The target of this IMPAS Questionnaire will be high school students in Indonesia. Using the ADDIE research model, the IMPAS Questionnaire was successfully developed and tested on 156 high school students. The IMPAS Questionnaire consists of 24 positive, negative, neutral positive, and neutral negative statements. The results of the CVR analysis and the Rasch model provide an understanding that the IMPAS Questionnaire has good content and construct validity. So, the IMPAS Questionnaire can be stated to have the ability to measure students' attitudes toward physics accurately. In addition, the results of the Rasch model analysis provide an understanding that the IMPAS Questionnaire has a moderate person reliability, excellent item reliability, and good internal consistency. Therefore, the IMPAS Questionnaire can be stated to have sufficient consistency in measuring students' attitudes toward physics. Thus, the development of an instrument to measure students' attitudes toward physics has been done successfully. Hopefully, this research can contribute to Indonesian education, especially to physics teachers and physics education researchers.
