Abstract

The development of information technology has brought significant changes to the medical device procurement process, particularly within government institutions such as the Health Office. The procurement of appropriate, efficient, and objective medical devices is crucial to supporting optimal medical services, yet the decision-making process is often constrained by limited budgets and the complexity of multiple assessment criteria. This study aims to design and implement a decision support system (DSS) based on the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method to provide recommendations for medical device procurement at the Binjai Health Office. The DSS evaluates six main criteria: price, quality, durability, ease of maintenance, medical necessity, and safety level, using procurement data from the 2022–2024 period. The TOPSIS method is applied to calculate the relative closeness of each alternative to the ideal solution, enabling decision-makers to rank medical device options objectively and systematically. The findings show that the DSS successfully prioritizes procurement alternatives, helping stakeholders allocate budgets more effectively and transparently. In addition, the system minimizes subjective bias by integrating quantitative analysis with clearly defined criteria. The system is implemented in a web-based environment with MySQL as the database, ensuring accessibility and scalability for future use. Overall, this research demonstrates that integrating TOPSIS into a decision support system can enhance the efficiency, accuracy, and accountability of medical device procurement in public health agencies. The study is expected to contribute to improving budget management and strengthening the quality of health services through better resource allocation.

Abstract

The development of automotive technology drives innovation in vehicle support components, including the continuously variable transmission (CVT) system, which plays a crucial role in transmitting engine torque and power to the wheels. One of the main elements in this system is the clutch lining and clutch housing, whose performance significantly impacts motorcycle performance. However, the standard pattern on these components is often not optimal in maximizing power delivery. Therefore, this study was conducted to analyze the effect of modifying the grooves of the clutch lining and clutch housing on engine torque in a 110 cc motorcycle. The research method used an experimental approach by varying the modification pattern on the clutch lining and clutch housing. The test motorcycle with a capacity of 110 cc was tested using a dyno test to measure torque and power at various engine speeds. Each modification variation was then compared with standard conditions to evaluate the resulting performance differences. The results showed that the pattern modifications on the clutch lining and clutch housing significantly increased torque. Several modification variations were able to significantly increase torque at medium to high speeds, thus providing better engine response and more efficient power delivery. Thus, this research contributes to the development of more optimal CVT component designs and has the potential to improve motorcycle performance, especially in the small capacity vehicle segment.

Abstract

The development of electric propulsion systems has become a major focus in efforts to provide energy-efficient and environmentally friendly air propulsion technology. One emerging innovation is the electric motor-based turbojet fan, which is expected to replace conventional fossil-fueled systems. As the need for energy efficiency increases, studies on electrical power consumption and airflow performance are crucial in supporting the development of new-generation propulsion systems. This study aims to evaluate the relationship between nozzle angle and the characteristics of electrical power consumption and airflow velocity in a double-spool turbojet fan. The method used is an experimental test with an ESP32-based control system. The duty cycle is set at 80% to maintain operational stability. Research data is obtained through measurements of electrical current, voltage, and airflow velocity. The nozzle angle variations tested include 13°, 19°, and 25°. The test results show a significant difference between nozzle angle variations on electrical power consumption and wind speed performance. The 13° nozzle angle produces the highest electrical power consumption, indicating a greater energy requirement to maintain airflow. Conversely, the optimal wind speed was found at an angle of 19°, indicating a balance between energy efficiency and aerodynamic performance. Meanwhile, an angle of 25° showed a decrease in performance in terms of both power and speed, making it less effective. In conclusion, the nozzle configuration has a direct influence on energy consumption and fluid dynamics in electric turbojet fan systems. This research provides an important contribution to the design of electric-based propulsion systems by emphasizing efficiency and performance aspects, while supporting the transition to environmentally friendly technologies.

Abstract

This research is a Classroom Action Research (CAR) conducted in two cycles. The subjects were 24 students of class XII TM 2 of the Mechanical Engineering Expertise Program at Semen Padang Vocational School in the odd semester of the 2025/2026 academic year. Data collection was carried out through learning activity observation sheets, practical assessment sheets, and multiple-choice tests to measure students' cognitive learning outcomes. The implementation of Creative Products and Entrepreneurship learning at Semen Padang Vocational School was previously teacher-centered. Students tended to be passive listeners during the learning process, which led to low participation, minimal interaction, and a lack of understanding of the material. As a result, most students were unable to achieve the Minimum Completion Standards (SKM). Based on this, the Jigsaw Cooperative learning model is considered suitable for application in Creative Products and Entrepreneurship learning, because it is able to create a student-centered learning atmosphere and encourage active involvement and cooperation between students. The results of the study prove that the application of the Jigsaw Cooperative learning model is effective in improving student learning outcomes. This is based on the average student learning outcomes in cycle 1 of 75.2, where 17 students were declared complete. In cycle II, the average student learning outcomes were 85.2 with 21 students declared complete. The significant improvement in cycle II indicates that the Jigsaw Cooperative Learning model is not only effective in improving cognitive learning outcomes but also able to improve the quality of interactions between students in the learning process. Students become more active in discussions, disseminating information, and are responsible for understanding the material they are learning and sharing with their groups.

Abstract

This study aims to analyze the results of Tungsten Inert Gas (TIG) welding joints made of 6061 aluminum with variations in current strength on mechanical properties. The current strength variations include 120 A, 140 A, and 160 A. The research method was conducted through laboratory testing, including impact testing, tensile testing, and microstructure testing. The results of the study indicate that variations in current strength have a significant effect on mechanical properties and weld joints. A current strength of 120 A produces a more uniform distribution of ferrite and pearlite phases in the weld zone compared to other variations. This is due to the electrical current during the welding process, which affects the heat input and cooling rate, consequently influencing the microstructure. As the current strength increases, the heat input increases, leading to changes in the material's phase composition and properties. Additionally, tensile test results showed an increase in tensile strength with increasing current strength, indicating that the welding process at higher current strengths contributes to improved material bonding and strength. Microstructure analysis revealed a more homogeneous phase distribution at higher current levels, which contributes to better weld quality and performance. This study provides valuable insights into how variations in current strength can be optimized for improved mechanical properties in TIG welding of 6061 aluminum, offering a basis for better control of welding parameters in industrial applications.

Abstract

This study aims to simulate the M/M/1 queueing system using Python through a Modeling and Simulation approach supported by the Discrete-Event Simulation (DES) method. The objective of the research is to analyze key performance indicators of queueing behavior, including arrival time, service time, waiting time, queue length, and server utilization. The methodology employs DES, which models system behavior based on discrete events such as customer arrivals, service initiation, and service completion. The simulation generates stochastic arrival and service times using Poisson and exponential distributions, respectively. The results indicate that the DES-based M/M/1 simulation accurately reflects theoretical queueing behavior, showing increases in waiting times and queue lengths when arrival rates approach service rates, while server utilization corresponds to system load intensity. The findings demonstrate that DES is an effective approach for analyzing queue performance and can be extended to more complex models such as multi-server systems, priority queues, and predictive simulations using artificial intelligence.

Abstract

This study discusses the design and development of an automatic safety system for a wood cutting machine using Arduino Uno, a PIR (Passive Infrared) sensor, and a servo motor as the main components. The system is designed to automatically stop the movement of the wood cutting machine when human motion is detected around the cutting area, thereby minimizing the risk of work-related accidents. The research method includes hardware design, microcontroller programming, and system response testing using two types of test objects: the human body and a wooden block. The results show that the system operates according to the programmed logic. When the PIR sensor detects human motion, the servo motor stops and the red LED lights up as a danger indicator. In contrast, when no human motion is detected, the servo motor continues to move normally and the green LED remains on as a safe indicator. The system’s average response time is 0.6 seconds, indicating a fast and accurate performance. Therefore, the designed system is considered effective and can serve as a prototype of a simple safety tool to enhance operator safety in wood cutting machines.

Abstract

A wall follower robot is a type of autonomous robot that is designed to move by following a wall at a certain distance. This research aims to design and build a Wall follower robot equipped with a Fuzzy-PID control system to improve navigation performance. The robot uses five HC-SR04 ultrasonic sensors to detect the distance to the wall and the surrounding obstacles. The data from the sensor is then processed by a Fuzzy-PID algorithm that combines the advantages of conventional PID control with fuzzy logic, resulting in a more adaptive response to environmental conditions. The test results showed that the robot with Fuzzy-PID control was able to maintain the stability of the distance to the wall more consistently compared to the pure PID control. In addition, the system exhibits better adaptability to complex environmental conditions, such as sharp turns, uneven wall surfaces, and the presence of resistance variations. The application of Fuzzy-PID control has been shown to improve the stability, response speed, and accuracy of the robot's navigation. These findings are expected to contribute to the development of robotic navigation systems for a wide range of practical applications, including automated cleaning robots, environmental exploration, and industrial systems that require reliable autonomous mobility.

Abstract

The disparity in the quality of rehabilitation services across regional work units presents a significant challenge to effective public management. This study aims to bridge the gap between problem diagnosis and policy prediction by proposing a hybrid, data-driven approach. We integrate K-Means Clustering to map the current state of service quality and Stochastic Simulation to predict the impact of strategic interventions. Using the 2024 Public Satisfaction Index (IKM) dataset from the National Narcotics Agency (BNN), the K-Means algorithm initially identified 26 work units (15.7%) in the "Red Zone" (critical performance), highlighting urgent areas for improvement. Next, a stochastic simulation modeling a "Directed Priority Intervention" scenario was run. The results predicted a significant structural shift in the distribution of service quality, characterized by an 80.8% decrease in critical units (down to 5 units) and a 71.8% increase in excellent performing units (up to 67 units). These findings validate that the integration of clustering and simulation provides a comprehensive framework for evidence-based decision-making, enabling policymakers to optimize resource allocation and efficiently accelerate national service standardization.

Abstract

The rolling process is a material forming method that is greatly influenced by the roll rotation speed parameter. Inappropriate rotation variations can cause various defects such as waves, tears, thickness irregularities, and ovalization. This review aims to compare the effect of variations in the roll machine rotation speed on the quality of rolling results on various types of materials, including Al6061-O aluminum plate, rubber sheets, and hollow and pipe-shaped materials. The method used is a literature study by collecting and comparing data on roll speed, defects that appear, deformation results, and process efficiency from several relevant journals. The results of the analysis show that high rotation speeds increase productivity but also increase the risk of defects because the material does not have time to adapt to deformation. Conversely, low rotation speeds produce more stable shapes and minimize defects, but are less efficient for mass production. Each material has a different optimal rotation range, including 23–36 rpm for Al6061-O plate, 45–72 rpm for rubber sheet formation, 24.4 rpm for hollow and pipe rolling, and around 21 rpm for corrugated plate. Overall, this study confirms that rotational speed control is a critical factor in achieving a balance between deformation quality and machining efficiency.
