Abstract

This research aims to develop a seaweed dryer using an Arduino Uno equipped with an Oled LCD and to help farmers dry seaweed during the rainy season so that the seaweed is not damaged.This research method uses research and development (R&D) with a prototype development model. The data collection technique used was a questionnaire. The subjects in this research were seaweed farmers in Palajau Village, Arungkeke District, Jeneponto Regency. This research produces a seaweed dryer using an Arduino Uno equipped with an Oled LCD. The result of this research is a prototype seaweed dryer that uses a temperature sensor to detect temperature and humidity, a heater to dry seaweed, a fan to distribute heat in the drying room and an Oled LCD to display temperature and humidity. In terms of Functionality and Usability, the results of the functionality feasibility percentage were 100% and as many as 10 respondents or 100% assessed that the tool developed based on the Usability context was at 100% in the very good category. Based on the results of testing seaweed using this dryer, the drying time for seaweed is 4-5 hours until the seaweed is dry with a capacity of 4 Kg for drying seaweed once.

Abstract

This study aims to design, implement, and evaluate a real-time electrical energy consumption monitoring system in the Haji Rani Building using the Arduino Uno microcontroller and the Blynk platform. The system integrates the PZEM-004T sensor for measuring voltage, current, power, and electrical energy, while the Wemos D1 Mini facilitates wireless data transmission via a Wi-Fi network. The research follows a Research and Development (R&D) methodology with a prototype development model. Data collection techniques include observation, documentation, and direct testing. The test results indicate that the developed system has a good level of accuracy, with an average deviation of 4.21% compared to standard measuring instruments. Despite minor deviations, the system successfully provides real-time monitoring with a fast response through the Blynk application, enabling remote access. Functionality evaluation using the Guttman scale, conducted by two content experts, confirms that the system meets the expected standards in terms of reliability, accuracy, and usability. However, the system's reliance on a stable Wi-Fi connection may affect monitoring reliability in areas with poor network coverage. Additionally, the accuracy of the PZEM-004T sensor, while acceptable for general monitoring, could be improved with more precise sensors. Future research should focus on integrating more accurate sensors, implementing machine learning algorithms for energy consumption analysis, and developing an automated IoT-based energy management system. By addressing these aspects, the proposed system can be further enhanced to improve energy efficiency and sustainability.

Abstract

Low energy absorption efficiency in static solar panels remains a key challenge for renewable energy implementation in Indonesia. This study aims to develop and evaluate an automatic solar panel drive system based on Arduino Uno, integrating an RTC module and INA219 sensor to optimize panel orientation according to real-time sun position. The methodology involved designing a prototype system consisting of a 10 Wp solar panel, SG90 servo motor, RTC DS3231 module, and INA219 sensor, tested outdoors under light intensity ranging from 800 to 1000 lux. Experimental results showed that the automatic system increased average voltage output to 13.9 V and enhanced energy capture by 6-12% compared to static panels under clear sky conditions. Usability assessments using the System Usability Scale indicated that the system was rated as highly effective and practical at the prototype stage. The novelty of this research lies in the integration of RTC-based time scheduling with servo motor control, offering a stable, low-cost alternative to LDR-based systems for photovoltaic optimization in tropical environments. The developed system has potential for broader implementation to improve solar panel efficiency, though further studies are recommended to validate performance over longer durations and diverse weather conditions
