Abstract

The limited availability of cellular networks in remote areas such as mountain trails and highland regions requires the development of a reliable, low-power, and easily deployable communication system. This study presents the design and implementation of a LoRa repeater based on the Ebyte E220-400T22D module to extend data communication coverage under both line-of-sight and non-line-of-sight conditions. The system utilizes an ESP32 microcontroller that controls two LoRa transceiver modules through a store-and-forward mechanism to retransmit data automatically. Experimental results show that the proposed repeater system effectively increases the communication range under various terrain conditions while maintaining signal stability and transmission reliability. The delay observed in data transmission remains within an acceptable range, confirming that the repeater operates efficiently without significantly affecting system performance. Overall, this work demonstrates that the Ebyte E220-400T22D-based LoRa repeater provides a practical and energy-efficient solution for long-range wireless communication in areas with limited telecommunication infrastructure.

Abstract

This study aims to evaluate the performance of the Circulating Water Pump (CWP) Unit 6 motors at PLTU Suralaya using a quantitative descriptive approach based on operational data from the Supervisory Control and Data Acquisition (SCADA) system and the Distributed Control System (DCS). The assessment covers key electrical and mechanical parameters by referring to international standards, namely IEEE Std 112-2017 and IEC 60034-14. Data were collected during 24 hours of stable operation, resulting in 288 measurement points. The findings indicate that the CWP 6A and CWP 6B motors operated within safe limits, as shown by current values of 190 A and 192 A, stator temperatures ranging from 74–79 °C, and vibration levels below 0.1 mm/s, which are significantly lower than the allowable limit of 4.5 mm/s. These results confirm that both motors are in stable and efficient operating condition. Furthermore, the integration of SCADA–DCS proves to be effective in supporting predictive maintenance for high-voltage motor systems.

Abstract

This study aims to develop a multisensor-based lightning strike zone detection device as an early warning system capable of identifying the risk level of lightning strikes in open areas in real time. The development specifically focuses on applying the Rolling Sphere Method to determine the boundaries between safe and hazardous zones based on open-space analysis. The sphere radius used in this method is processed into risk-zone calculation parameters, which are then implemented in a microcontroller system integrated with multisensors to monitor the user’s position and movement. The resulting zone mapping is visualized in the form of an ellipse illustrating a 50% lightning-strike probability within the safe area. The system provides automatic notifications through a smartphone when the user enters a hazardous zone (red zone), prompting immediate mitigation actions. Experimental results show that the device can accurately detect user movement and map risk zones with high precision. Thus, the proposed prototype has strong potential as an effective safety tool for reducing the risk of lightning-related injuries in open environments

Abstract

Effective machinery and supporting systems significantly influence production capacity, precision, and workflow continuity. In several companies, the lifting of hardened furan sand is still performed using forklifts, leading to delays and reduced efficiency, particularly during night shifts. This condition highlights the need for a more reliable material handling system. This study aims to design a conveyor system capable of transporting hardened sand to the sand crusher machine as an alternative to forklift-based handling. The conveyor is designed to match the height and spatial constraints of the existing sand crusher and can be operated without forklift assistance. The design process includes problem identification, product requirement definition, concept development, and concept evaluation. The results indicate that the second design concept provides the best performance, with a maximum stress of 60.729 MPa, supported by six structural frames, and a total manufacturing cost of Rp 37,923,000. The proposed conveyor system offers a more efficient and practical solution for material handling in sand-processing operations.   Keywords: Manufacturing industry, production efficiency, conveyor system, sand crusher

Abstract

In Indonesia's poor, frontier, and remote areas, access to power is still hampered by a lack of network infrastructure and high transportation costs for fossil fuel supply. The techno-economic viability of an off-grid solar power system without a generator set in the vicinity of Nduga Regency is examined in this paper. HOMER Pro software was used for modeling. Local solar radiation potential, daily electricity consumption profiles, battery characteristics, and estimates about maintenance and investment costs were among the input data. The research concentrated on dependability metrics like Loss of Load Probability (LOLP) and indicators like Levelized Cost of Energy (LCOE), Net Present Cost (NPC), and Internal Rate of Return (IRR) in order to identify the best battery SPP configuration. According to simulation studies, solar systems with battery-based energy storage are both economically competitive during the project time and can supply off-grid populations with dependable electricity. However, this design necessitates a substantial initial expenditure due to logistical and topographical challenges. Using off-grid solar power plants without generators is a promising way to increase electrification, improve energy security, and lessen reliance on fuel supply chains, according to the research.

Abstract

Three-phase induction motors are widely used in industrial applications due to their simple construction, high reliability, and relatively low maintenance cost. However, motor rotational speed is strongly dependent on the supply frequency, making the drive susceptible to speed deviations outside the allowable range. Both under-speed and over-speed conditions can lead to thermal stress, mechanical degradation, increased current draw, and premature motor failure. This study proposes a microcontroller-based monitoring and protection system designed to detect abnormal speed conditions in three-phase induction motors. A Hall effect sensor is utilized to measure the instantaneous rotational speed, while programmable speed limits are input through a keypad interface. The system automatically disconnects the motor supply once the detected speed exceeds the predefined threshold. The experimental results reveal that the system successfully identifies under-speed (e.g. 1391 rpm) and over-speed (e.g. 1509 rpm) conditions from predetermined set points (e.g., 1400 rpm and 1500 rpm), and automatically disconnect the motor with a fast response (2 seconds), confirming the effectiveness of the protection algorithm. This work contributes to low-cost and scalable protection solutions suitable for industrial motor applications, particularly for implementations requiring autonomous speed protection without high-end control equipment.

Abstract

Motorcycle theft is a common criminal act in society. Therefore, a vehicle security system is needed that can provide a fast response and real-time location information. This research aims to design and implement a theft detection and tracking system for motorcycles based on the WIFI using NodeMcu ESP8266, SW- 420 vibration sensor, and GPS NEO-6M module, integrated with a web server interface for remote control and monitoring. The research uses hardware and software engineering methods, with a Waterfall approach. The research stages include literature studies, problem identification, system design, tool assembly, software development, system testing, and evaluation. The components used include ESP8266, SW-420 vibration sensor, NEO-6M GPS, and relay module. The system is designed so that when vibration is detected, an alarm is activated and a notification is sent via email. GPS will send the vehicle coordinates to the Web Server to be monitored by the user. Test results show that the system can respond to vibration disturbances within an average of 1 second, control the engine and starter relays within 1–3 seconds, and track the vehicle's location with an average accuracy of 8.33 meters and a tracking delay of approximately 50 seconds. The system was successfully accessed via smartphone hotspot with a maximum effective range of 15 meters. Therefore, this system is proven to be an effective, practical, and affordable IoT- based solution for motorcycle security that can be easily accessed by users through mobile devices.
