Abstract

The number of small and medium sized metal smelting industries whose working processes produce large waste heat energy. This results in almost 40% of energy being wasted as high temperature exhaust gases. This percentage is able to be converted into electrical energy with the concept of a thermoelectric generator using peltier elements. The way to use it is to use TEG (Thermoelectric Generator) whose function is to convert heat into electricity by utilizing temperature differences. The purpose of this research is how exhaust temperature optimization, the number of peltier elements to the thermoelectric generator voltage output on a used metal melting furnace. Then the analysis is done to get the optimum Seebeck coefficient as a representation of the thermoelectric generator performance. The design of this study is an L20 orthogonal matrix with three replications using a factorial design. The independent variables varied were exhaust temperature, number of peltier elements and data analysis using ANOVA Two Way. Based on the results of the research data it can be concluded that the furnace wall temperature affects the TEG current output. Where the most optimal wall temperature is 480 ºC which produces a TEG current output of 168 mA. This indicates an increase in the temperature of the used metal smelting furnace walls increasing the TEG current output. While the number of peltier elements does not influence the TEG current output

Abstract

This Classroom Action Research (CAR) aims to improve the mathematics learning outcomes of fifth-grade students at SDN Besuk 1 through the implementation of the Realistic Mathematics Education (RME) approach supported by concrete media. The study was motivated by students’ low academic performance in mathematics and their limited engagement during the learning process. The research adopted the Kemmis and McTaggart action research model, which was carried out in two cycles. Each cycle consisted of four stages: planning, action, observation, and reflection. The subjects of the study were 25 fifth-grade students. Data were collected through classroom observation, student learning assessments, and documentation. The instruments used included observation sheets for learning activities and evaluation test items. The findings showed a significant improvement in students’ learning outcomes, with the percentage of students achieving the minimum learning criteria increasing from 40% in the pre-cycle to 60% in the first cycle, and reaching 88% in the second cycle. Moreover, there was a notable improvement in students’ learning activity, particularly in terms of participation, engagement, and conceptual understanding. The use of concrete media enabled students to grasp mathematical concepts more meaningfully and contextually. Therefore, it can be concluded that the RME approach combined with concrete media is effective in enhancing fifth-grade students’ mathematics learning outcomes.
