Abstract

Determination of suitability test on digital mammography have been conducted from 2016-2018 at a hospital in Makassar City using voltage accuracy parameter. This measurement was used detector, and X-ray multimeter. Statistically, voltage accuracy parameter has correlation value, r = 0.866 (perfect correlation). While the p value obtained in voltage accuracy parameter is p < 0.05. There are significant differences in value from 2016-2018. The result of the suitability test for voltage accuracy parameter is still within the tolerance limit as recommended by the IAEA.

Abstract

This study aims to develop digital comics for learning magnetism in learning Science in Elementary Schools. This type of research is development research, which refers to the Four-D. The location of this research is at Kota Tengah 80 Public Elementary School, Bulangu Timur 1 Public Elementary School, and Telaga Biru 1 Public Elementary School. The results of the study show that digital comic magnets developed for science learning in elementary schools: (1) are categorized as valid and feasible; (2) Practically used, this is indicated by the very good response from students with a percentage of 90% in the limited trial class and 93.75% in the extended trial class. The implementation of learning in the limited trial class obtained an average percentage of 90.91%, while in the extended trial class it was 96.15%; (3) Effectiveness, indicated by good student activity with a percentage of 82% in both limited trial classes and extended trial classes, as well as student learning outcomes that are in very good criteria. Based on this, the digital comics magnet that has been developed is stated to be valid, practical and effective, so that it can be used in the science learning process in class V of elementary school

Abstract

This study aims to determine the effect of applying the android-based Jire collaborative learning model on momentum and impulse material to improve student learning outcomes. The research method is a quasi-experimental design with a one-group pretest-posttest research design. The research location at SMA Negeri 6 Gorontalo Utara for the 2021/2022 academic year used four research samples, namely class X IPA 1 as the experiment class and class X IPA 2, X IPA 3, and X IPA 4 as the replica class. This research begins with the preparation of learning tools that physics learning experts and learning media experts validate. The results of the validation show that the learning tools are valid and can be used in the learning process. The implementation of the learning process in this study is in the excellent category and can improve student learning outcomes. The N-Gain value for the experimental class and replica class is in the high category. Student responses to using the android-based Jire collaborative learning model show good and excellent categories. This shows that the Jire collaborative learning model can be used to improve student learning outcomes in physics learning
