Abstract

DC motors are widely applied in various fields due to their simple design, ease of control, and capability to generate high torque at low speeds. Position control of DC motors is crucial to ensure the performance and accuracy of the motorized electro-mechanical systems. The most common conventional control utilized in DC motors is the Proportional Integral Derivative (PID) controller. However, selecting the proper parameters for that controller is challenging. In this paper, the Linear Quadratic Regulator (LQR) approach is used to determine PID controller parameters for DC motors. The LQR approach, based on optimal control theory, offers a systematic alternative to traditional trial-and-error methods for tuning PID controllers. The proposed method improves the performance and efficiency of DC motors by optimizing the PID parameters, ensuring precise control and energy utilization.

Abstract

An infusion pump is an intravenous injection machine for administering high-alert type drugs. Failure to administer this type of drug can result in the patient's death. One of the causes of failure is disturbances in the infusion fluid flow rate, which is influenced by the performance of the stepper motor. This research proposes a PI control design for controlling flow rate stability in infusion pump machines. PI is applied by simulating Simulink using the Ziegler Nicholes type 1 tuning method and creating a 1st-order transfer function using the Cian Cone method. The system is also applied directly to the hardware and tested using standard medical calibration tools. The simulation results show that the PI control can reach the set point and maintain stability with a rise time of 19.49 seconds and a settling time of 32.39 seconds. In actual testing of the infusion pump machine with PI control, the average level of accuracy of the flow rate reached 98%, and the stability reached below 0.3 ml/h. This proves that the infusion pump that has been successfully created can be used to administer high-alert drugs precisely according to the dosage and can be used for a long time with constant delivery quality.

Abstract

In the context of the Online Learning activity, where video content plays a crucial role in educational materials, the demand for effective video production systems has become essential. Traditionally, at least two people are needed to operate cameras, which poses a challenge due to limited human resources. This study addresses this issue by developing a Camera Position Tracking System using image processing, specifically utilizing the MediaPipe framework for real-time tracking of presenters. The system's mechanics enable a DSLR camera to automatically adjust its position based on the presenter’s movement, detected within a range of 1.5 to 8 meters. The light intensity required for optimal operation is between 125 and 190 lux. The system's success lies in converting detected position data into motor stepper pulses that move the camera, ensuring efficient, cost-effective video production with minimal human intervention.

Abstract

This study aims to analyze the effect of nanofluid concentration and panel tilt angle variation on photovoltaic-thermal (PV/T) system efficiency using numerical simulation with the Finite Element Method (FEM). The results showed that the optimal nanofluid concentration of 20% resulted in an even distribution of fluid flow, while increasing the concentration to 20% at an inclination angle of π/6 decreased the PV cell temperature, increased the photovoltaic efficiency to 12.04%, and the best electrical power of 36.71 W. The highest thermal efficiency of 69.5% was achieved at a concentration of 20% with an inclination angle of π/6, while the highest total efficiency of 81.7% was achieved at an inclination angle of π/3. The optimal combination of nanofluid concentration and tilt angle was shown to significantly improve the energy efficiency of the PV/T system, making an important contribution to the development of more efficient renewable energy technologies.

Abstract

The increasing reliance on self-service systems in academic libraries necessitates robust service desk man-agement to ensure user satisfaction and operational efficiency. At the UIN Sunan Ampel Library, self-service systems provide convenient access to various services, but their performance remains underexplored. Evaluat-ing the library's service desk management using the ITIL V4 framework reveals critical insights into its effec-tiveness and areas for improvement. The framework’s Service Desk Practice Success Factors (PSF)—Acknowledge, Classify, Own, and Act—are used to assess how well self-service systems align with ITIL best practices. This research adopts a qualitative descriptive methodology, utilizing interviews and data analysis to evaluate service desk processes. The findings indicate significant benefits in accessibility and user empower-ment through self-service features. However, challenges persist, including manual acknowledgment workflows, insufficient SLA implementation, and limited real-time monitoring capabilities. These issues hinder optimal service delivery and responsiveness. To address these gaps, the study recommends integrating automation for acknowledgment tasks, developing measurable SLA policies, and implementing comprehensive training for library staff. Additionally, real-time tracking tools should be incorporated to enhance system efficiency and user experience. Despite these challenges, the study underscores the potential of ITIL V4 to improve library service desk management, ultimately fostering better user satisfaction and operational excellence.

Abstract

The coffee roasting process is essential for creating distinctive aromas and Flavors. Manual roasting often results in uncontrolled temperatures, resulting in uneven and burnt coffee beans. Therefore, an automatic roasting machine was developed to control stable temperatures at setpoints of 180°C (light roast), 220°C (medium roast), and 250°C (dark roast), with a monitoring system to ensure optimal results. Servo angle settings are used to optimize temperature stabilization, while a DC fan serves to remove excess heat from the machine. The system uses an Arduino Uno and ESP32, with a Thermocouple Type K temperature sensor and an I2C LCD display for real-time monitoring. Integration with IoT Blynk allows remote monitoring and control through a mobile application. Research shows that a servo angle of 140° provides the optimal temperature increase, while an angle of 100° is effective for lowering the temperature when it exceeds the setpoint. These angles are used in the system to keep the temperature controlled according to the specified target.

Abstract

Current Transformers (CTs) are essential components in power system protection, ensuring accurate current measurement for relay operations.. This study evaluates the accuracy of protection CTs used in 20kV feeders at the Bangka Transmission and Substation Service Unit. Measurements were conducted on CTs with 5 and 7 years of usage to analyze ratio error and knee voltage compliance with IEC 61869-2 standards. The results indicate that all CTs meet the standard, with ratio errors below 1% and knee voltages exceeding 60V. Normality tests confirmed that the data are normally distributed, allowing statistical analysis using t-tests. The t-test results showed no significant difference in ratio error and knee voltage between CTs used for 5 and 7 years. This study concludes that aging over this period does not significantly affect CT accuracy, ensuring continued reliability in power system protection.
