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.

Abstract

The purpose of this research focuses on the development of electronic modules (e-modules) based on the SAVI (Somatic, Auditory, Visual, and Intellectual) learning model, which specifically targets high school students studying buffer solution materials. This research uses the 4-D model development framework, including the defining, designing, and developing stages. Initial needs analysis showed a significant gap in the utilization of electronic learning media at SMA Negeri 1 Pancur Batu. The resulting e-module consists of 39 pages and is designed to meet diverse learning styles through interactive elements and multimedia aids. Validation by experts showed that the e-module was very feasible, with an average value of 78.37% material expert assessment and 88.3% media expert assessment. In addition, feedback from teachers and students showed strong engagement and effectiveness, with an average teacher assessment score of 90.75% and 89% average student assessment. This research highlights the importance of integrating modern technological advances into chemistry education to improve student learning outcomes. Keywords: Development, E-module, Buffer solution, SAVI
