Abstract

Geographically, Indonesia is located in three rings of active plates and surrounded by various active mountains that make Indonesia prone to earthquakes. When the earthquake occurred, there were still many people who were late in getting information to carry out the early evacuation process. This research aims to provide solutions to people who are late in receiving earthquake information by developing a microcontroller-based earthquake early warning system alarm with MPU6050 accelerometer sensors and NodeMCU ESP8266 to minimize possible losses. This research uses the Research and Development method with the ADDIE development model, to develop an Arduino uno-based earthquake alarm from previous research. This research uses a literature study system for analysis of earthquake problems when an earthquake occurs. The results of this study are in the form of a tool equipped with an Arduino Uno microcontroller system, where the earthquake warning system is run according to the system design. The tools developed were validated by three expert lecturers using validation questionnaires. Data analysis was carried out quantitatively to determine the feasibility of Arduino-based earthquake early warning tools using the Likert scale. Based on the average results of validation tests by experts, 91% of earthquake early warning tools developed are in the very decent category. Based on the trials carried out, the tool can provide warnings to the public directly

Abstract

Students' understanding of learning materials will increase with the presence of teaching aids. This study aims to produce a product in the form of a Doppler effect demonstrator based on Arduino Uno with FC-04 and HC-SR04 sensors in high schools, as well as to assess the feasibility of the developed teaching aids and determine students' responses to the developed teaching aids. This research is a type of development research (RD) using the ADDIE development model. The research subjects consist of 2 physics education lecturers as media expert validators, 1 teacher at one of the high schools in Kota Bengkulu as a material expert validator, and 65 students from12th grade Science at one of the high schools in Bengkulu City. The research instruments used were needs analysis sheets, material expert and media expert validation sheets, and student response sheets. Data collection was carried out through questionnaires distributed to the validators and students. The results of media and material validation tests obtained average scores of 85% each, categorized as very feasible. Based on these results, it can be concluded that the Doppler effect practical demonstrator using FC-04 sensor and Arduino Uno is feasible. As for the student response results, the average score obtained was 85%, categorized as very good.

Abstract

In fact, the physics learning process in senior high schools does not encourage students to think critically, resulting in low learning outcomes. This research aims to test the effectiveness of a scientific-based flipped class model to enhance students' critical thinking abilities. The research method used is a quantitative method with a quasi-experimental design, specifically nonequivalent pre-test post-test control group design. The population of this study consists of all tenth-grade science classes at Kutacane State Senior High School 3, and the sampling technique used is total sampling, where tenth-grade science class I serves as the experimental group, while the tenth-grade science class II serves as the control group. The instruments used are observation sheets, tests, and questionnaires. Data were analyzed using the N-Gain test, the classical completeness test, and student response analysis. The results of the study showed that critical thinking skills, as measured by both the classical completeness test and N-Gain test, improved in both classes, with the experimental class showing a high gain index category, while the control class showed a moderate gain index category. Learning using a scientific-based flipped class model is effective in enhancing students' critical thinking abilities because it can facilitate students in accessing the provided learning materials.

Abstract

In general, the assessment model used by teachers in teaching only revolves around summative assessment, thus students cannot use it to identify the strengths and weaknesses of their skills in learning activities. This study aims to determine the effectiveness of the Assessment for Learning instrument in project-based physics learning to measure collaboration and problem-solving skills. The research design utilizes a pretest-posttest control group design. The population for this study includes all second-semester eleventh-grade science students, with the sample comprising eleventh-grade science 3 as the experimental group and eleventh-grade science 4 as the control group selected through random sampling technique. The instruments used include the Assessment for Learning learning assessment instrument and assessment to evaluate and improve students' collaboration and problem-solving activities. Data collection techniques involve observation and questionnaire collection. Data are analyzed using descriptive statistical data analysis and inferential statistics. The hypothesis testing results of collaboration and problem-solving skills indicate differences in collaboration and problem-solving skills between the experimental and control classes in project-based physics learning. It is concluded that assessment using AfL in project-based physics learning is effective in measuring collaboration and problem-solving abilities as it exceeds classical mastery.

Abstract

The importance of practical implementation, especially in science subjects, is challenging for educators, students, and schools. Many findings are related to various obstacles and problems regarding implementing practicum in the laboratory, so the implementation is considered ineffective. This research aims to determine students' perceptions of implementing practicum in the science laboratory. This study used a survey method with a quantitative approach involving 96 respondents, consisting of 48 students in 8th grade at Junior High School 1 Kuantan Hilir and 48 students in 8th grade at Islamic Junior High School 1 Sentajo Raya. The instrument used was a questionnaire consisting of 26 statement items. The data collection technique was done by distributing questionnaires directly and then conducting descriptive analysis. The results of this study indicate that students' perceptions of the practical implementation in the science laboratory are in a good category (72.50%). In general, the practical implementation in the science laboratory for grade 8 students at Junior High School 1 Kuantan Hilir and Islamic Junior High School 1 Sentajo Raya has been carried out well. It can be concluded that students have a good perception of the implementation of practicum in the science laboratory.
