Abstract

Penelitian ini mengkaji pengaruh penggunaan radiasi gamma di bidang kesehatan, salah satunya adalah penggunaan sinar gamma dalam proses radioterapi. Penyerapan energi radiasi ke dalam tubuh dapat menyebabkan munculnya radikal bebas dalam tubuh yang dapat merugikan organ lain di sekitar target penyinaran. Penelitian ini bertujuan untuk mengetahui pengaruh paparan radiasi gamma terhadap hepar mencit dan sifat hepatoprotektif ekstrak kulit manggis(Garcinia mangostana) dalam mengurangi kerusakan sel yang ditimbulkan. Penelitian ini dilakukan dengan memberikan ekstrak kulit manggis 5 dosis varian berbeda ke mencit dan diberi paparan radiasi selama 40 menit dengan dosis total 268 μSv selama 14 hari, kemudian diukur kadar SGPT (serum glutamic pyruvic transaminase) dan jumlah kerusakan sel dari preparathistopatologis. Hasil penelitian menunjukkan kadar SGPT turun menjadi 77,7 U/L dari kadar awal 128,67 U/L. Hal ini membuktikan bahwa ekstrak kulit manggis memiliki sifat hepatoprotektif yang dapat mengurangi kerusakan sel akibat paparan radiasi gamma.

Abstract

This study aims to develop a two-level Natural Science (IPA) test instrument based on the jumanji game in measuring understanding of the concept of work and simple planes. The research method in this case is a quantitative method with a modification of the development model. The measurement instrument developed in this study is a two-level science test or a reasoned multiple choice test specifically for the business chapter and simple planes. This research instrument that has been developed was tested on 256 students of SMP Abu Bakar. The results of this study indicate that a measurement instrument has been produced in the form of a two-level science test based on the jumanji game which can measure students' understanding of concepts about business and simple and reliable machines that are valid and reliable. These results are evidenced by the validity and reliability of the two-level science test, which are 0.83 and 0.53 respectively. Meanwhile, the achievement of students' understanding of concepts related to business and simple machines is 51% which is in the high category. The students' conceptual understanding measured using the two-level science test is high because it exceeds the minimum criteria that have been determined.

Abstract

This study aims to create STEM-based science teaching materials based on simple electrical circuits and determine the feasibility of STEM-based teaching materials. Research and development of the Dick & Carey model is the type of research used. The research process comprises four stages: needs analysis, product design, validation and evaluation, and testing. Material experts, presentation experts, linguists, and graphic experts are all involved in expert validation. Teachers who teach science subjects participate in the product feasibility test. Individual, small group, and field trials assess students’ readability. Expert validation revealed that the content aspect was 97.7 % with a very decent category, the presentation aspect was 97.7% with a very proper category, the language aspect was 85% with a very decent category, and the visual aspect was 80 percent with a worthy category. The science teacher’s feasibility test results showed that the content aspect was 90 % with an excellent category, the presentation aspect was 98.6% with an outstanding category, and the language aspect was 96.7% with a superior category. Students’ readability test results showed an average score of 87.7% in the excellent category. Based on the validation and legibility trials findings, developing STEM-based science teaching materials (Science, Technology, Engineering, and Mathematics) on simple electrical circuit materials is feasible. It can be used as a learning resource.

Abstract

This study aims to describe the effectiveness of the use of a spring oscillator practicum on students of SMA Negeri 1 Indramayu and SMA Negeri 2 Indramayu. The method used is the ADDIE model R & D method using a one group pretest-posttest design. The results showed that the calculation of the n-gain score of 0.688 and 0.680 obtained the interpretation of increasing student learning outcomes in the medium category. Meanwhile, students' responses to the spring oscillator practicum tool obtained an average score of 82.3% from the three aspects with the interpretation of the score "good". From the research data, it can be concluded that the use of a spring oscillator is effective in high school physics learning
