Abstract

This study examines the development of a solar-powered drying system that integrates Internet of Things technology to increase the efficiency of drying agricultural products. The problems faced by small farmers, especially related to inefficiencies in drying methods, are the background for this research. The main objective is to design and implement a system that uses an ESP32 microcontroller and a DHT-11 sensor for real-time temperature and humidity monitoring. The applied methodology includes system design, prototype testing, and data analysis from field experiments. The results show that this system can increase drying efficiency by up to 30% compared to traditional methods. These findings confirm that the application of IoT technology in drying systems not only offers technical solutions, but also contributes to the welfare of small farmers by reducing post-harvest losses.Keywords: Solar dryer system; Internet of Things; Drying efficiency; Small farmers; Reduction of post-harvest losses. AbstrakStudi ini meneliti pengembangan sistem pengering tenaga surya yang mengintegrasikan teknologi Internet of Things untuk meningkatkan efisiensi pengeringan hasil pertanian.

Abstract

Remote-controlled robots often face challenges related to communication stability and limited signal range. This study aims to design and develop a 4WD (Four Wheel Drive) robot based on Arduino Uno using NRF24L01+PA/LNA wireless communication and to evaluate system performance in terms of control responsiveness and communication reliability. The research method includes system design, hardware and software implementation, and performance testing under various distance conditions. The evaluated parameters include response time, data transmission success rate, and maximum communication range. The results show that the system achieves a communication success rate of 100% at 1 meter, 99% at 10 meters, and 96% at 50 meters. At the maximum distance of 200 meters, the system maintains a success rate of 75%. The response time is relatively low, enabling real-time control performance. This study contributes to the evaluation of NRF24L01 wireless communication performance in a 4WD robot system for remote control applications.

Abstract

LPG gas leakage is a serious household safety threat in Indonesia, where 88.59% of households use LPG as their primary cooking fuel. Although colorless and faintly odorous at low concentrations, its flammable nature can cause explosions or fires if undetected. This research aims to compare MQ-4 and MQ-5 sensor performance in a single Arduino Uno-based gas leakage detection system. A quantitative experiment with direct comparison was conducted under identical conditions inside a sealed acrylic chamber measuring 16 × 12 × 10 cm, using LPG gas from a refillable lighter to simulate household leakage. Parameters measured include sensitivity, defined as the slope of the log(Rs/R₀) versus log(relative ppm) curve, and reading stability from the standard deviation of repeated measurements, where Rs is sensor resistance when exposed to gas and R₀ is resistance in clean air. All ppm values are relative estimates based on official sensor datasheets. Results show MQ-5 has higher sensitivity with a slope of 0.7914 compared to MQ-4 (0.6505), while MQ-4 is more stable with a log₁₀(Rs/R₀) standard deviation of 0.656 compared to MQ-5 (0.669). The system successfully detected all 30 leakage scenarios (100%) without false alarms, with a classification success rate of 99.0% per session. This research recommends MQ-5 for rapid early detection and MQ-4 for long-term monitoring requiring data consistency, thus both contribute as empirical evidence for a simple, accurate, and economical gas leakage detection solution.
