University Technology of Yogyakarta (UTY) has released the UTY Student Portal Application since 2020 which is an improvement in services to support student academic activities. The UTY Student Portal application was developed by Puskom from Yogyakarta Technology University. The UTY Student Portal application is a system designed and built to manage data related to academic information which includes student data, lecturer data, lecture results records, lecture schedules and so on. The presence of this Student Portal Application has given rise to various comments from its users, namely UTY students. Seeing this problem, the researchers conducted research on student opinions regarding the UTY Student Portal Application using the Naïve Bayes Classifier. This research uses the Python programming language. Based on the results of the discussion, it was found that the accuracy level was 93% in the training process and the testing accuracy was around 65.2% with a distribution of training and test data of 70%:30% from 150 opinion text data. This model creation experienced overfitting, because the resulting testing accuracy was much smaller than the training accuracy.

Monitoring temperature and humidity in textile storage warehouses is vital for maintaining product quality and ensuring optimal conditions. This study focuses on developing a temperature and humidity control unit using an ESP32 microcontroller, evaluating its performance through black-box testing. The ESP32-based system offers a scalable and energy-efficient solution for climate control, delivering precise environmental monitoring through integrated Wi-Fi and Bluetooth for affordable connectivity. Its advanced real-time data processing capabilities and compatibility with multiple sensors make it highly suitable for cost-effective, large-scale implementations in textile storage environments. The experimental approach involves controlling temperature and humidity as independent variables, while ensuring optimal storage as the dependent variable. The DHT21 sensor, ESP32 microcontroller, and relay are used as control variables. Software was developed in the Arduino IDE to manage temperature and humidity, and after validation, the program was uploaded to the ESP32 for black box testing. Results confirmed that the system effectively regulates these conditions, crucial for preserving textiles. The ESP32 efficiently serves as the control unit, and testing validated its ability to maintain desired limits. Future improvements could include wireless access for remote monitoring, enhancing flexibility and operational efficiency in environmental control for textile storage.

AK-Tekstil Solo is a vocational campus with several workshops for lectures, one of which is the Spinning and Weaving Workshop. It has yarn and fabric manufacturing machines and holds the most significant electricity consumption for machine operations, lighting, and other instruments. Hence, a smart workshop room with electrical energy efficiency is crucial. This research aims to design and develop a smart workshop lighting system using an Arduino-based microcontroller circuit and photocell components. The light intensity setting system is performed by determining the measurement point of light intensity and measuring the natural and artificial light intensity as the input for photocell and relay. An automated lighting system for the smart workshop was then developed using a photocell censor based on the Arduino Mega microcontroller. Product testing shows that the automatic switches and relays based on programming successfully work the automated system.

Competition for jobs is getting higher because the number of job seekers is greater than the availability of job opportunities, resulting in increased unemployment. Tight competition in the world of work requires the work readiness of graduates from vocational colleges, to have expertise and skills in their fields and be ready to work. This study aims to analyse the effect of self-efficacy, work motivation, soft skills and industrial practice on work readiness in AK-Tekstil Solo vocational students. This study uses a quantitative descriptive approach. The sampling technique was saturated sampling with a sample of 97 students of class 2023 AK-Tekstil Solo. The data analysis technique uses statistical analysis, namely multiple linear regression tests, T tests, F tests, and coefficients of determination. The results showed that self-efficacy, soft skill work motivation, industrial practice had a positive and significant effect on student work readiness. Self-efficacy, work motivation, soft skills, and industrial practice have a significant and simultaneous effect of 93.4% on the work readiness of AK-Tekstil Solo vocational students. Thus increasing self-efficacy, work motivation, soft skills, and industrial practice will increase the work readiness of AK-Tekstil Solo vocational students.

Robotic technology continues to advance, but real-time position tracking of robot movements still faces challenges, especially in dynamic and irregular environments. Sensors often fail to maintain accuracy due to environmental disturbances. This study introduces an innovation using omnidirectional wheels on a three-wheeled robot and image-based position control to improve maneuverability and precision. This method utilizes an infrared camera mounted on the ceiling to detect the robot's position. Image processing algorithms are used to determine waypoints and direct the robot. Omni-directional wheels allow the robot to move freely in all directions, which is important for accurate navigation on complex trajectories. The robot was tested on the "X" and "Square" trajectories in a 1.8-meter x 1.8-meter room to rotate vertical, horizontal, and diagonal movements. The test results showed that on the "X" trajectory, the second movement had the most significant error with a Mean Absolute Error (MAE) of 134.96, while the third movement had the slightest error with an MAE of 52.49, with an average error of 91.36. The first and third movements in the “Square” trajectory showed more significant errors than the second and fourth movements, with MAE of 105.37 and 100.47, respectively. The second and fourth movements had MAE of 67.20 and 59.65, with an average error of 83.17. These results indicate that the image-based control system and omnidirectional wheels improve accuracy compared to conventional methods, which is important for robot navigation applications. Practical implications of this technology include potential applications in the robotics and automation industry. Future research should focus on developing more precise control algorithms and sensors to improve accuracy. Directions for future research include exploring more sophisticated image processing techniques and applying this technology to various industrial scenarios.
