Abstract

E-LKPD is a medium students can use to train themselves and hone their ability to master a learning material. As a training medium, E-LKPD is one of the evaluation tools that can be used to measure student achievement in the learning process. For this reason, the compiled E-LKPD should pay attention to the elements of student characteristics and learning conditions. This research was conducted at SMA Swasta Bersama Berastagi. This type of research is Research and Development (R&D) using the ADDIE model with the stages of Analysis, Design, Development, Implementation, and Evaluation. The data used in this study are test data on learning outcomes for understanding concepts using the compiled E-LKPD and questionnaire data from distributing questionnaires to measure student enthusiasm in learning. The subjects in this study were 35 students of class X SMA Swasta Bersama Berastagi. E-LKPD was designed interactively with the Canva application and validated by experts with 2% and 87%. Scores The SMA Swasta Bersama Berastagi trial showed a significant increase in student scores, from an average of 60.25 to 79.85 after using E-LKPD. Students also responded positively through questionnaires, showing increased motivation, engagement, and understanding. These results prove the effectiveness of E-LKPD in improving the quality of learning and are recommended for application to other materials. This study uses the ADDIE model to develop interactive E-LKPD to enhance students' understanding of static fluids. The results showed a significant increase in students' average scores after using E-LKPD. In addition, students felt more interested and active in learning, indicating the effectiveness of this learning media.

Abstract

This study aims to analyze the fixed carbon content and combustion rate of briquettes made from banana peel waste as a renewable energy alternative. The experimental method was used, involving key stages such as material preparation, carbonization process, briquette molding, and testing of fixed carbon content and combustion rate. The results showed that the fixed carbon content of the produced briquettes reached 87%, indicating good combustion quality and high energy storage capacity. Additionally, the combustion rate of the briquettes varied, with Sample A having a combustion rate of 0.017 grams/s and Sample B at 0.014 grams/s. This difference suggests that Sample B has a longer combustion duration. Thus, banana peel briquettes have the potential to be an efficient and environmentally friendly alternative fuel. Further research is needed to optimize the production process and enhance briquette efficiency.
