Abstract

The advancement of technology in the agricultural sector has spurred the implementation of automation systems to optimize efficiency and productivity through the Internet of Things (IoT) concept. This study aims to design and implement an integrated ESP32 microcontroller-based Smart Greenhouse system for real-time monitoring and control of environmental parameters. The system architecture integrates a series of sensors including soil moisture, temperature, light intensity, and motion sensors, supported by an LCD as a local interface and the Blynk application for remote monitoring. The methodology used is an experimental system engineering design approach that includes the design, implementation, and performance testing phases. The test results show that the system is capable of accurately acquiring environmental data and disseminating information synchronously through local and cloud platforms. In addition, the automatic control mechanism is proven effective in activating water pump actuators based on fluctuations in soil moisture parameters with a short response time. These findings confirm that the implementation of an IoT-based Smart Greenhouse system can improve the efficiency of crop management through watering automation and remote monitoring. This research has the potential to be developed on an industrial scale with optimization of sensor precision and network connectivity stability.

Abstract

This study aims to design and implement a prototype of an Internet of Things (IoT)-based early warning system for river water level rise and landslide potential. The system utilizes an ESP32 microcontroller as the main controller integrated with multiple environmental sensors, including an ultrasonic sensor for water level measurement, a soil moisture sensor, a vibration sensor, and a temperature and humidity sensor. The research method used is experimental, involving system design, hardware implementation, software development, and functional testing. The system is capable of monitoring environmental parameters in real-time and classifying conditions into three levels: safe, alert, and danger. The results show that the system successfully detects changes in environmental conditions and provides warnings through visual indicators, audio alarms, and IoT-based notifications. The multi-parameter approach improves the accuracy and reliability of the system in identifying potential flood and landslide risks. This prototype demonstrates effective performance and has the potential to be further developed into a real-world disaster mitigation system.

Abstract

Accidents involving large vehicles such as trucks are often caused by blind spots that restrict the driver’s view. This research aims to develop a mictocontroller-based blind spot detection system capable of detecting objects, distinguishing between humans and inanimate objects, and adjusting detection system capable of detecting objects, distinguishing between humans and inanimate objects, and adjusting detection sensitivity according to environmental conditions. This system uses an Arduino Uno as the main controller, integrated with two ultrasonic sensors to detect the distance of objects in front and behind the vehicle. The Passive Infrared (PIR) sensor detects the presence of humans based on body heat radiation, while the Light Dependent Resistor (LDR) sensor sets the detection threshold to 30 cm in bright conditions and 50 cm in dark conditions. The Inertial Measurement Unit (IMU) sensor makes the system active only when the vehicle is moving, thus saving power. The results show that the system detects objects with high accuracy within the specified distance range, correctly distinguishes humans, and responds well to changes in light and vehicle movement. This system is expected to be an effective solution to improve driving safety in large vehicles through early warning in blind spot areas.

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

This activity describes the planning, installation, and evaluation of the implementation of a Solar Power Generation System (PLTS) at the Istiqomah Community Reading Park, Terjun Village, Medan Marelan District. The objectives of the activity are (1) to provide a reliable independent power supply for lighting and auxiliary learning devices at the reading park, (2) to increase the managers’ capabilities in operating and maintaining the PLTS, and (3) to assess the technical and social sustainability impacts after installation. Methods used include an energy needs and peak load survey, design of an off-grid system based on the survey results, installation of main components (PV panels, controller, batteries, inverter), and operational and maintenance training for the reading park managers. Evaluation was conducted through measurements of energy availability (hours of lighting operation), reduction in consumption from the PLN grid (kWh), and user satisfaction questionnaires. Based on the needs survey, the reading park’s electricity use is mostly allocated to lighting, fans, and computer operation. Results show that the installed PLTS successfully supplied 95% of the reading park’s daily electricity needs, directly resulting in monthly electricity savings of up to Rp 250.000,00. The results indicate that the designed PLTS meets lighting and light electronic device needs during the reading park’s operating hours, reduces dependence on external supply, and increases community participation in literacy activities, making it an effective strategy for achieving energy independence.

Abstract

The rapid growth of Internet of Things (IoT) technology has increased the demand for flexible and user-friendly wireless connectivity in embedded systems. One of the most widely used modules in IoT applications is the ESP8266, which integrates a microcontroller and WiFi capability in a compact and low-cost platform. Despite its advantages, WiFi configuration on the ESP8266 is commonly implemented using static credentials that are hardcoded into the firmware. This approach requires recompilation and reprogramming whenever network parameters change, making it inefficient and impractical for end users and large-scale deployment. This research proposes the design and implementation of a WiFi Manager system on the ESP8266 module to enable dynamic WiFi configuration without modifying the firmware. The proposed system allows the ESP8266 to automatically switch to Access Point (AP) mode when it fails to connect to a previously stored network. Users can then configure WiFi credentials through a web-based interface using a standard web browser. The configuration data are stored in non-volatile memory and used to reconnect the device in Station (STA) mode once a valid network is detected. The research methodology includes system design, firmware development using the Arduino platform, and functional testing to evaluate connectivity performance and reliability. Experimental results show that the WiFi Manager system successfully simplifies the WiFi configuration process, achieves a high connection success rate, and provides stable reconnection after power reset. The proposed approach enhances usability, deployment flexibility, and scalability of ESP8266-based IoT devices.

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.
