Abstract

The change in curriculum to a Merdeka Curriculum causes changes in the learning system in Indonesia because this requires teachers and students to be more innovative and creative. To balance this requires teaching materials that can meet these needs, especially renewable energy materials; this material is new, so there are still few teaching materials available. The available renewable energy teaching materials are not carried out in practicum, so teachers still use references to the previous curriculum teaching materials, which are no longer significant. This type of research is educational development research or Educational Design Research (EDR). The stages of development research consist of 3 main stages: preliminary research, prototyping stage, and assessment phase. The development model used in this research is the Plomp development model developed by Tjreed Plomp. The research instruments used were interview sheets and questionnaires in the form of validity sheets which were analyzed with Aiken's V scale and practicality sheets. The validity test results were obtained by Aiken's V scale of 0.93 with high validity, which means that the developed teaching materials are valid. The practicality test results for the small group were 89% with very high practicality. Based on the teacher response questionnaire with very high practicality and obtained 93% based on the student response questionnaire with very high practicality, the teaching materials developed are practical. Based on the study's results, the teaching materials of the Independent Curriculum on renewable energy Phase E are valid and practical.

Abstract

Organic inhibitors utilization to reduce corrosion rate on metal has been widely studied because of their environmentally friendly nature. This study aims to calculate the value of the corrosion rate of A36 steel, the efficiency of inhibitors from the extract of Kersen leaf, and determine the corrosion that occurs in the material of A36 steel. The method used is weight loss. The sample was immersed for seven days with inhibitor concentration variations of 0 ppm, 100 ppm, 200 ppm, 300 ppm, 400 ppm, and 500 ppm. The results showed that the extract of Kersen leaf can reduce the corrosion rate. The corrosion rate decreases as the number concentration of the inhibitor is added to the test medium. In contrast, the inhibitor efficiency increases with increasing amounts of inhibitor concentrations added to the test medium. The lowest corrosion rate value and the highest efficiency at adding 500 ppm inhibitor concentration are 0,0767 mmpy and 38,83%, respectively. Based on the results of the microstructure of A36 steel after immersion, pitting corrosion is formed in the form of holes on the steel surface. On steel without inhibitors, corrosion products are more, and the surface is rougher than steel samples added with inhibitors.
