Abstract

The tobacco processing industry has a large economic impact. In the process of storing tobacco, it is necessary to pay attention to the temperature and humidity conditions of the room. The process of monitoring the storage room will be difficult if the manager is outside the industrial environment. Therefore, an Internet of Things-based room temperature and humidity monitoring system was created using Wemos D1 as a controller, the Blynk Application interface and real-time Telegram notifications. The Blynk application can monitor all the latest information and set the temperature and humidity set points of the device. The Telegram bot can provide notification information if the temperature and humidity set points are not appropriate. The manager can immediately take effective action based on information from the emergency warning system.

Abstract

Companies engaged in the steel industry utilize machines and lifting equipment to support productivity. Hoist cranes are lifting machines widely used in companies, ports, factories, warehouses, and the steel industry. They are mechanical devices used to move objects from one place to another. However, one common problem with hoist cranes is the occurrence of overcurrent in the motor, which triggers the circuit breaker to trip. In such cases, the operator must climb onto the chassis or body of the hoist crane to reset the system manually. To address this issue, an IoT-based hoist crane monitoring and control system was developed using a power sensor module to measure real power (Watts), voltage (Volts), current (Amperes), and power factor (pf) in real time via an internet connection. The collected data is then processed by a microcontroller. The main components used in this system include the ESP32 microcontroller, PZEM-004T current sensor, and relay. The results of this study demonstrate that the IoT-based hoist crane motor monitoring and control system functions properly and meets the research objectives. Keywords: Hoist Crane, ESP32 Microcontroller, PZEM-004T Sensor, IoT.

Abstract

The Indonesian Robot Contest (KRI) is an annual event organized by the Ministry of Research, Technology, and Higher Education. One of its divisions, the Indonesian Search and Rescue Robot Contest (KRSRI), focuses on designing robots for disaster victim identification. This research aims to develop a victim identification system for the KRSRI robot of ITN Malang using image processing techniques and the K-Nearest Neighbors (KNN) algorithm, designed to distinguish between actual victim dolls and dummy dolls based on color and shape characteristics. The research utilizes a Raspberry Pi 3 Model B+ and a Raspi Cam V2 camera to capture images, which are processed using image segmentation techniques to detect the orange-colored victim doll, while the KNN algorithm is applied for object classification. Experimental results show that the accuracy of victim detection varies depending on the K parameter in the KNN algorithm and the distance between the camera and the object. At a distance of 10 cm, 15 cm, and 20 cm, the highest accuracy achieved is 100% with certain K values, whereas at 25 cm, the accuracy drops significantly, reaching only 43.75% to 31.25%.

Abstract

This study investigates the design and implementation of an off-grid solar photovoltaic (PV) system for a meatball cart as a renewable energy solution for small mobile food businesses that still commonly rely on conventional energy sources for lighting and heating. The developed system integrates a 120 Wp monocrystalline PV module, a 12 V 100 Ah LiFePO4 battery, a PWM solar charge controller, a 1000 W inverter, and an automatic soup-heating subsystem based on a DS18B20 temperature sensor, thermocontroller, and solid-state relay. Field testing was conducted on a meatball cart in Pakis District, Malang Regency, for two weeks of operation. The results show that the system was functionally able to operate the supporting loads and maintain soup temperature within 85–95°C through automatic switching control. However, the total daily load of 3810 Wh was still higher than the available daily energy of about 1920 Wh. This finding indicates that the current configuration is feasible as an implementation prototype but has not yet achieved fully autonomous full-load operation. Overall, the study demonstrates the potential of integrating off-grid PV and closed-loop thermal control to reduce dependence on fossil energy and improve the operational flexibility of micro-enterprises.

Abstract

This study aims to analyze the impact of radiator leakage in the main transformer on the power generation performance at the Ampelgading Hydroelectric Power Plant, Malang. Radiator leakage reduces the volume of insulating oil, leading to increased operating temperatures and degradation of insulation quality. A quantitative descriptive method with a case study approach was employed by analyzing temperature data, Breakdown Voltage (BDV), Dissolved Gas Analysis (DGA), and energy production data before and after the disturbance. The results indicate that radiator leakage caused a significant increase in winding and oil temperatures, along with a decline in insulation oil quality marked by elevated dissolved gas levels. Operationally, the disturbance resulted in a power output reduction of 18.27%. Corrective actions, including cold welding, load reduction, and oil purification, were effective in restoring transformer performance, as evidenced by an average BDV value of 68.1 kV categorized as very good, and improved energy production after maintenance. This study concludes that the reliability of the transformer cooling system, particularly the radiator, plays a crucial role in maintaining operational stability and efficiency in hydroelectric power generation.

Abstract

High population mobility requires travel services that are fast, transparent, and able to provide reliable vehicle position information. However, many travel service providers still use manual booking and reporting mechanisms, so customer service, data management, and vehicle monitoring are not yet optimal. This study aims to design and implement a web-based travel booking system integrated with real-time vehicle tracking using Internet of Things technology. The system was developed using the Adaptive Software Development method through the stages of speculation, collaboration, and learning. Vehicle position data were acquired using a Global Positioning System NEO6MV2 module connected to a NodeMCU ESP8266 microcontroller, then transmitted to a server through a web-based application programming interface and displayed on the booking dashboard. System testing showed an average data transmission delay of 1.8 seconds, a data delivery success rate of 98%, and coordinate accuracy within ±3–5 meters. These findings indicate that the proposed system can improve booking data management, accelerate vehicle location monitoring, and increase service transparency for users and administrators. In conclusion, the integration of Internet of Things-based tracking and Adaptive Software Development provides an effective approach for developing adaptive, responsive, and integrated telematics applications for travel service operations.

Abstract

Growing energy demand and the depletion of fossil fuel resources have increased the need for sustainable alternative energy sources. Solar energy is suitable for tropical regions and can be applied to small-scale charging systems. This study designs and implements a temperature monitoring and control system for a solar-powered mobile phone charging box to maintain internal temperature stability and support battery charging performance. The system uses a NodeMCU ESP8266 microcontroller, DHT22 sensor, cooling fan, lighting load, Wi-Fi communication, and Blynk Internet of Things platform for real-time smartphone monitoring. Temperature and humidity data are collected inside the box and transmitted to Blynk, while the fan is activated automatically when the temperature exceeds the predefined threshold. Test results show that the system detected changes in operating conditions. When the fan was off and the lamp was on, the temperature was 28°C with 68.40% humidity. When the fan was on and the lamp was off, the temperature reached 30°C with 78.50% humidity. Solar panel output varied from 19.9 V, 0.393 A, and 7.834 W in the morning to 16.02 V, 0.16 A, and 2.563 W in the afternoon. These findings indicate that the proposed system can support real-time monitoring and automatic thermal control.
