Abstract

Rice warehouses in Indonesia experience significant post-harvest losses, reported to reach 10–20% annually, primarily due to poor environmental control and fire incidents. This study develops and evaluates an Internet of Things (IoT)-based environmental monitoring prototype for rice warehouses, utilizing the ESP32 microcontroller, DHT22 temperature-humidity sensor, and a flame sensor. The ESP32 was chosen for its low power consumption and robust connectivity, while DHT22 and the flame sensor were selected for their balance of accuracy, sensitivity, and cost-effectiveness. System calibration employed a digital thermohygrometer and a standard flame detector to ensure measurement validity. Experimental tests were conducted in a controlled laboratory setting with three sensor points, simulating temperature variations of 28–45°C and humidity of 60–95%, together with 24-hour reliability tests and scenarios involving fire detection at a 30 cm distance. The system achieved sensor error margins within ±0.5°C for temperature and ±2% for humidity, with actuator response times of 1–3 seconds. Real-time Telegram notifications were successfully delivered within 2–3 seconds. The integration of multi-sensors, automated actuators, and instant notifications distinguishes the proposed system from conventional approaches and previous studies. While effective for small-to-medium scale warehouses, limitations remain in fire sensor coverage and dependence on internet connectivity. The system offers an adaptable, efficient, and reliable solution to minimize manual errors and improve rice warehouse management. Future work will address broader scalability, additional gas sensors, GSM communication, and cloud-based data logging for enhanced safety and analytics.

Abstract

— The cooling system of geothermal power plants (PLTP) critically depends on cooling towers, particularly the basin as the reservoir for cooled water to be recirculated into the system. Real-time monitoring of basin water temperature and weather conditions is essential for maintaining operational efficiency and prolonging equipment lifespan. Manual observation and wired systems are limited in terms of range and response time, prompting the need for a more advanced monitoring solution. This article describes the development and implementation of a LoRa-based monitoring  system that integrates temperature and weather sensors in the cooling tower basin of a geothermal power plant. The research was conducted through literature reviews, direct observation, consultations with experts, and comprehensive field testing of both hardware and software under various operational scenarios. The designed system consistently transmits temperature and weather sensor data with a success rate exceeding 95%, and achieves an effective transmission range of 400–500 meters in open geothermal areas. Implementation of this system results in increased data acquisition speed, improved energy efficiency, and enhanced monitoring accuracy, supporting faster technical responses and better risk management. Evaluation results confirm that the LoRa-based solution functions optimally and is highly applicable for deployment in challenging and remote geothermal industrial environments.

Abstract

Group travel in densely populated areas presents risks of losing members, especially during peak periods such as weekends. This study aims to develop a wireless communication glove device as an aid for inter-member detection to prevent loss during travel. The method involves designing a device based on the Wemos microcontroller integrated with GPS sensors for position tracking, MAX30100 heartbeat sensor for health monitoring, an OLED I2C display as visual interface, and a buzzer as alarm. The system functions by identifying unique IDs between devices within a certain radius and triggers an alarm when connection is lost. Testing results indicate the heartbeat sensor accuracy with an average deviation of less than 3 bpm compared to manual measurements. Maximum connection distance without physical obstacles ranges from 24 to 26 meters, decreasing to 18 meters with wall obstructions. The master device detects connection loss within approximately 20 seconds, indicated by an audio alarm and display changes on the OLED screen. The estimated operational duration is 5.5 hours at 2.4 Watts power consumption. Overall, this device effectively prevents member loss with simple health monitoring and reliable connection detection features.

Abstract

This community service activity aims to develop branding strategies and optimize digital marketing for Kapapah Jaya Catering, an SME in Palembang, in order to increase competitiveness. The activity was carried out through the Merdeka Belajar Kampus Merdeka (MBKM) internship program for 4 months (October 2024–January 2025), involving 5 students from various study programs. The method used was Participatory Action Research (PAR), which included situation analysis, participatory observation, in-depth interviews, and work program implementation. The work program implemented included visual identity redesign (rebranding), social media content optimization, product packaging design innovation, and the implementation of a Corporate Social Responsibility (CSR) program in the form of sharing activities in the surrounding environment. The results of the activity showed the creation of a new logo and consistent visual identity (color palette and font), which improved the professional image of the SMEs. This activity provided tangible benefits in the form of increased brand visibility and competitiveness of SMEs in the digital culinary market, while also proving that academic-business collaboration can be a concrete solution to the challenges of SME digitalization.
