Abstract

This research is experimental and aims to determine the characteristics of the SP1848-27145SA generator thermoelectric module in the form of power generated and its performance as a power plant by utilizing heat energy from a combustion furnace. The method used in testing the thermoelectric characteristics of the generator is a direct experimental method by measuring the output voltage, current, hot side, and cold side of the thermoelectric and the power generated by the module attached to the combustion furnace. Thermoelectric testing of the SP1848-27145 SA generator as a power plant by utilizing heat energy from a combustion furnace with a maximum voltage generated electronic device load of 2.25 Volts at ΔT 46°C and a maximum generated power of 0.09 watt. The thermoelectric performance of the SP1848-27145 SA generator is obtained in three different configurations: single, series, and parallel. The highest thermoelectric power produced is in the series configuration, where the power obtained is 0.25 watts, while the results from the parallel arrangement have the same power value. very small, namely 0.02 watts, and the highest efficiency value only reaches 3.40%.

Abstract

This study aims to develop an IoT-based prototype system for monitoring soil moisture and controlling irrigation in chili plants using the Blynk platform. The research employs a Research and Development (R&D) approach with a prototypedevelopment model. The system integrates a capacitive soil moisture sensor (Soil Moisture Sensor Capacitive V1.2) to measure soil moisture levels and automate irrigation decisions. The system's effectiveness was evaluated through 56 trials, achieving a 98.15% success rate, indicating high reliability in providing real-time soil moisture data. The usability assessment showed that all respondents rated the system positively, with functionality reaching 100% feasibility and usability rated at 86.3%, categorized as very good. However, further analysis is needed to validate the questionnaire used in usability testing and assess whether training is required for farmers to operate the system efficiently. In terms of reliability, the system recorded a 5% sensor accuracy deviation, highlighting the need for additional calibration and comparative testing with alternative sensors. Overall, this system has the potential to enhance agricultural productivity and optimize water usage, reducing dependence on manual irrigation. Future research should focus on improving system connectivity, refining sensor accuracy, and expanding the system's application to various crops and environmental conditions to promote sustainable and technology-driven farming practices.
