Abstract

The development of Internet of Things (IoT) technology provides solutions to improve the efficiency of monitoring and managing plant environments, particularly in greenhouse systems. A common problem is the lack of optimal monitoring of environmental conditions such as temperature, air humidity, soil moisture, and light intensity, which significantly affect plant growth. This study aims to design and implement a prototype smart greenhouse monitoring system based on IoT using the ESP32 microcontroller to monitor environmental conditions in real-time and support automatic irrigation. The research method used is an experimental approach involving system design, assembly, and testing in an indoor environment using potted plants. The system utilizes a DHT11 sensor for temperature and humidity, a soil moisture sensor for soil conditions, an LDR sensor for light intensity, and an ultrasonic sensor for measuring water level. The collected data were analyzed descriptively to evaluate system performance. The results show that all sensors function properly and are able to detect environmental changes accurately, and the system successfully transmits data in real-time to a monitoring platform. The implication of this research is that the developed system can serve as an effective solution for automated plant monitoring and irrigation in small to medium-scale applications.

Abstract

Limited access to electricity in chili farming areas in Parbuluan District, Dairi Regency, hinders charging water pump batteries, mobile phones, and providing lighting for farming activities. This community service program aimed to develop a portable Solar Power Plant (PLTS) as an alternative energy source to improve farmers' work efficiency. The implementation methods included field observations, interviews, system design and assembly, user training, field implementation, and evaluation. The results demonstrated that the portable PLTS successfully supplied electricity for charging water pump batteries, mobile phones, and LED lighting directly in the farming area. Based on interviews, farmers reported that the system eliminated the need to return home, located approximately 3 km from the farmland, for charging electrical devices. This reduced travel time by an estimated 6 hours per month, allowing more time for productive farming activities. In conclusion, the portable PLTS provides an effective and sustainable alternative energy solution that improves work efficiency and supports agricultural activities in areas with limited access to electricity.

Abstract

Penelitian ini membahas secara komprehensif perancangan sistem manajemen termal (thermal management system) pada energy strorage system (ESS) berbasis baterai lithium-ion yang diaplikasikan pada Stasiun Pengisian Kendaraan Listrik Umum (SPKLU). Sistem ini dirancang untuk menjaga suhu operasional baterai tetap dalam kisaran yang aman melalui pendekatan pendinginan pasif menggunakan Phase Change Material (PCM) serta pelat pendingin berbahan aluminium. Metode penelitian dilakukan secara eksperimental melalui simulasi numerik menggunakan perangkat lunak SolidWorks, dengan dua skenario utama yaitu simulasi kondisi pengisian cepat (fast charging) dan simulasi pelepasan energi. Hasil simulasi menunjukkan bahwa sistem mampu menjaga suhu BMS tidak melebihi 58°C, sementara suhu pelat pendingin utama dapat mencapai serendah 43°C pada saat pelepasan energi. Sistem pendingin yang dikembangkan menunjukkan kinerja yang optimal dalam menyebarkan panas secara merata, menjaga kestabilan suhu kerja baterai, dan meningkatkan efisiensi serta keselamatan operasional dari ESS pada SPKLU. Dengan demikian, desain sistem ini dapat menjadi solusi inovatif untuk mendukung keberlanjutan teknologi kendaraan listrik di masa mendatang. KATA KUNCI: energy strorage system; SPKLU; thermal management; lithium-ion; phase change material
