Abstract

Brick is a building material that is still widely used by people today. Most of the small-scale brick-making industries print bricks in the traditional way. Of the problems encountered by adding a conveyor as a means of carrying soil that has been printed and then running through the conveyor to the brick makers to add security to the brick makers. The stages of the research were carried out by identifying the problem to produce data from the system to be made, then designing the concept for making the tool. In tool making, the most important components are conveyors, dc motors and PLCs as the main controls in running conveyors. This conveyor works to bring the dough quickly to the craftsmen so that the dough can be measured for the speed of time and the level of safety for the craftsmen. This research has succeeded in creating a "Conveyor Control System in Automatic Brick Making". Conveyor time testing in automatic brick making produces 2 seconds per minute when one brick is on the conveyor and in increasing safety for conveyor makers this can provide good security.

Abstract

Abu Robocon 2019 will be held in the country of Mongolia with the competition theme "The Great URTUU Spreads Knowledge". The 2019 Indonesian ash robot contest made 2 robots, namely MR 1 (Manual Robot) which is run automatically and MR2 (Automatic Manual). In one of the race sessions there was a section of throwing saghai balls. The parameter that must be achieved is the optimization of the embattlement mechanic by landing a throw on target and getting maximum points. The KRAI 2019 robot thrower uses pneumatics. The wind pressure determines the throwing force of the saghai ball. Angle testing to find out the right angle in order to achieve a good and precise on-target throw. Based on the test results of the pitcher's angle of 500, the ball was thrown 20 times resulting in the robot being able to throw well and the average speed was 4.82 m/s. It can be concluded that the angle of 500 is the right angle to produce a lot of 50 points. Testing with a throwing angle of 600, the ball was thrown 20 times resulting in the robot being able to throw, as well as the average speed produced which was 5.20 m/s. The third test with an angle of 700, the ball was thrown 20 times resulting in the robot being able to throw, as well as the average speed produced which was 6.17 m/s. Testing the angle of 500 is the right angle because it can produce a good throw and produce 50 points.

Abstract

The development of RFID technology in the field of education is quite interesting, including the implementation of an automated presence system that is integrated with the database that supports the processing of information about the presence of lectures. The app consists of several major components, such as an RFID Tag, an RFID Reader, and the ESP32 microcontroller. RFID Tags are used to read data and serve as student IDs. This tool system is integrated into the website according to the concept of the Internet of Things. This concept is the communication between the tool system and the website; data is automatically stored directly into the database that has been provided. The mode used by the presence system consists of two modes, namely list mode and presence mode. The functionality of the system hardware and software has been tested to ensure that the tools and components work properly and can function as required. The test results showed that the distance required to be able to read RFID Tags was 0 to 2.5 cm, the read time of an RFID Tag was an average of 2.39 seconds, and the update time of website data was 3.33 seconds. The performance of the system in testing failed to read an RFID Tag three times, with a success rate of 85.71%.

Abstract

Bricks are the main component in a building, the increasing demand for bricks makes bricks sought after by the public so craftsmen have to produce enough bricks to meet market needs. From this problem, a design of an automatic brick dough mixer using a 1-phase AC induction motor was made, a concept design was carried out for making tools. In making the tool, the most important component of this research is the 1 phase AC induction motor where this motor will work to stir a dough so that it is evenly mixed. So that the humidity level of the dough can be measured with a moisture sensor, what is the level of density in a brick mixture that is made. To test the humidity level so that the dough becomes dense, 3 L of water and 9 L of soil are obtained at a temperature of 63%, the average cut in one minute is 24 bricks and for manual manufacture it produces 3 bricks in one minute so that it can be obtained conclusion with this tool the brick craftsmen can be helped to speed up production results in order to obtain efficiency in work results.

Abstract

Automatic control system or control system (control system) is a system that aims to control a process so that the output produced can be controlled so that no errors occur. Automatic control in a system is very necessary because not all can be controlled by humans with precision, so it is necessary to have a control system that can monitor at the same time as the desired command execution. This research is to design a prototype irrigation sluice control system using a potentiometer, PID algorithm, PLC OMRON CP1E NA20DR-A and DC PG 28 motor as actuator. This research was conducted at the system design stage, both in hardware design and software design. The results of the tests that have been done show that the PID works well, this can be known from the state of the Output Word value "0" if the value "SP = PV" while the Output Word value will be greater than zero if "SP PV". Data collection is carried out with a water level condition of 12 cm then to raise the water condition, then add water slowly, from the data obtained that shows the increase in water level at the potentiometer voltage is 0.116 V / cm.

Abstract

Natural disasters frequently disrupt electrical infrastructure, creating critical challenges for emergency response, healthcare delivery, and community recovery. Portable solar photovoltaic (PV) systems have emerged as a sustainable and rapidly deployable solution for off‑grid energy provision in disaster‑affected regions. This review provides a comprehensive synthesis of portable PV technologies for post‑disaster applications, encompassing system architectures, component selection, deployment configurations, and operational performance. Particular emphasis is placed on DC‑first designs, modular scalability, energy storage integration, and IoT‑enabled monitoring, which collectively enhance efficiency, reliability, and usability under harsh environmental conditions. The analysis highlights persistent challenges related to energy efficiency, storage resilience, system standardization, and user accessibility, while underscoring the importance of integration into broader emergency energy ecosystems. Research gaps are identified in areas such as efficiency optimization, human‑centered design, and scalability, providing guidance for the development of next‑generation portable PV systems. By consolidating technical and operational insights, this review establishes a foundation for advancing portable PV systems as robust emergency energy solutions, bridging the gap between immediate relief and long‑term resilience in disaster‑prone regions.

Abstract

Energy resilience is a critical requirement in disaster-prone regions, where electrical infrastructure is highly vulnerable to natural hazards and prolonged power outages. Portable and modular solar power systems have emerged as promising solutions for enhancing resilience by enabling decentralized, rapidly deployable, and grid-independent energy supply. This paper presents a comprehensive review of the role of portable and modular photovoltaic-based power systems in improving energy resilience from a power electronics perspective. The review synthesizes recent literature on resilience concepts, system architectures, and converter-based control strategies relevant to emergency energy applications. Particular emphasis is placed on DC-first and hybrid AC/DC architectures, modular converter topologies, battery management systems, and energy management strategies that support reliable and fault-tolerant operation under variable and uncertain conditions. Practical deployment and performance considerations, including scalability, robustness, monitoring, and usability in disaster environments, are also discussed. The findings indicate that well-designed portable and modular solar power systems can significantly reduce recovery time, improve operational continuity, and decrease reliance on centralized grids and fuel-based generators. This review identifies key technical challenges and research opportunities to guide future development of resilient power electronic-based energy systems for disaster response and recovery.
