This research is motivated by the location of Indonesia in disaster areas. But the readiness of citizens to deal with disasters is still low. This study aims to (1) develop natural disaster learning packages with the vision of the Science Environment Technique Society (SETS) which is integrated in science subjects, (2) implement disaster prepared teaching materials, (3) improve teacher understanding and skills, students about concepts, principle, the practice of saving oneself in the event of a natural disaster. This research was conducted in collaboration with teachers in primary and secondary education. Theoretical exploration and expert evaluation are carried out on the features of themes and sub-themes of disaster learning models that are integrated in SETS vision science subjects. Data analysis technique used (1) descriptive percentage, (2) normalized gain test, and (3) t-test. The results of this study in the form of five features of learning models such as (1) syllabus, (2) lesson plans, (3) learning methods, (4) teaching materials, and (5) assessment instruments. Desimination of the five features was declared feasible to increase students’ understanding of disasters. This is seen from the test results obtained by students experiencing an increase (gain) from pretest to posttest starting from 53.5% to 80.3%.
This study aims to analyze the effectiveness of the science model of volcanic dust disaster approach to LiTMas (environment, technology, and society) developed for the mitigation of volcanic dust disasters before they are used in large scale trials. The package to support the development of the disaster science lecture model include the guide book model, semester learning plan, lecture program unit, reference books, lecture media, practical guides, disaster simulation guides, lecture products, and evaluation instruments. The method used in this research is the research and development (R&D) method. Subjects in the study were students of the Physics Education Study Program Faculty of Teacher Training and Education. This research produces a model of disaster science lectures by LiTMas approach that is valid, practical, and effective for mitigate volcanic ash disasters as a result of volcanic eruption activities.
The value of the gravitational acceleration of the earth above the earth’s surface depends on the position of the latitude and longitude of the earth’s surface, in other words, because the shape of the earth’s surface is not round like a ball. The magnitude of gravity is not the same everywhere on the surface of the earth. The purpose of this study is to analyze the value of the earth’s gravitational acceleration in a laboratory using a current balance with a graphical method. Fluctuations in the value of the magnetic field strength (B) and the value of the electric current strength (i) on the current balance cause the value of laboratory gravitational acceleration (glab) to vary in the transfer of electric charge (q) according to coil type. The magnitude of the earth’s gravitational acceleration value obtained in a laboratory with a current balance for each type of coil is as follows: SF-37 glab-nr=9.89 m/s2, SF-38 glab-nr=9.90 m/s2, SF-39 glab-nr=9.76 m/s2, SF-40 glab-nr=9.95 m/s2, SF-41 glab-nr=9.75 m/s2 dan SF-42 glab-nr=9.93 m/s2. The results obtained indicate that the value of the earth’s gravitational acceleration in a laboratory close to the literature value is the value of the glab-nr in the SF-37 coil type of 9.89 m/s2.
Mitigation education is a stage of preparedness to minimize losses due to a disaster. The purpose of this study is to develop teaching materials with the SETS (Science, Environment, Technology, and Society) approach Integrated Science subjects of solar system competencies and the earth surface structure to reduce the risk of the Mount Lokon volcanic ash disaster in North Sulawesi Province. This research uses Research and Development Methods. The subjects in this study were 30 students at SMP Kristen Credo Kolongan, Minahasa Regency. The results showed that the teaching material developed was declared valid by experts, practical was used, and effectively viewed from the cognitive aspect with an increase in the pretest score (54.5) to the posttest (92), and the affective aspects of the average score very good average (87.3) so that this teaching material is valid, practical, and effectively used in learning activities to reduce the risk of volcanic ash disaster.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
