Abstract

The Miniature Micro Hydro Power Center (MHPC) media is a development of learning media. The use of MHPC miniature learning media can improve critical thinking skills for elementary school students in Indonesia. The way the MHPC miniature works is similar to the original, namely the Karekan MHPC (MHPC in the Karekan Area). Research objective: to create a miniature MHPC media product and test the effect of using miniature MHPC on critical thinking skills. This study uses the ADDIE Research and Development model. Research methods: 1. product validation test developed by science content experts (1 lecturer), media validation by five experienced teachers, technicians, nine practitioner teachers as users; 2. Quasi Experiment, to test the effect of the use of miniature MHPC on critical thinking skills, involving 102 students of class V (sample of 4 classes from 4 schools, consisting of 2 experimental classes and two control classes) from 7 schools (as population) in the Kihajar Dewantara cluster, North Purwokerto District, Banyumas Regency, namely SDN Grendeng 1, 2, 3, and 4. The data from the posttest were tested for normality, homogeneity, and an independent sample T-test using SPSS 2022. The results of the study: the validation results of science content experts, experienced teachers, technicians, and nine practitioner teachers (using CVI) gave the product a > 85 with the comment "MHPC miniature media is suitable for use in learning". The results of the normality and homogeneity tests obtained significant values of 0.09 and 0.6, where sig>0.05. The results of the Independent Sample T-test showed a positive effect of the use of MHPC miniature media on critical thinking skills in the experimental class compared to the control class, which only used MHPC Kareka video media; a significance value of 0.00<0.05 was obtained. Skepticism: The results of the development of MHPC's miniature products can be used in science learning and have a positive effect on students' critical thinking skills.

Abstract

The Miniature Micro Hydro Power Center (MHPC) is a learning media development designed to improve critical thinking skills in elementary science education. The operation of this miniature resembles that of the actual MHPC Karekan, located in Banjarnegara, Indonesia. This study aimed to develop the MHPC Miniature media, evaluate its validity, and test its effectiveness in enhancing students' critical thinking skills. This research employed the Research and Development (R&D) method, using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The research stages included an assessment of teacher and student needs, followed by product validation by material experts (one science lecturer and five experienced teachers), technicians, and nine practitioners. To test its effectiveness, 102 fifth-grade students from the Ki Hajar Dewantara Cluster in North Purwokerto District were selected as the research sample. The sample was divided into an experimental and a control group using a cluster sampling technique. Data from the posttest were analysed for normality and homogeneity before an Independent-Samples T-Test. The results indicated that validation by science experts and practitioners yielded a Content Validity Index (CVI) of > 0.85, indicating the media is highly suitable for learning. Furthermore, the Independent Samples T-test showed that the experimental group using the MHPC miniature performed significantly better than the control group, which used only video-based media (ρ < 0.05). In conclusion, the developed MHPC miniature is a valid and effective tool for fostering critical thinking skills in elementary science learning. These findings imply that integrating contextualized miniatures into the science curriculum can bridge the gap between abstract concepts and real-world applications, providing a scalable model for innovative STEM education.
