ETL scheduling is a challenging and exciting issue to solve. The ETL scheduling problem has many facets, one of which is the cost of time. If it is not handled correctly, it may take a very long time to execute and inconsistent data in very large data. In this study using Round-robin algorithm method that proved able to produce efficient results and in accordance with conventional methods. After doing the research, the difference between these two methods is about execution time. Through this experiment, the Round-robin scheduling method gives a more efficient execution time of up to 61% depending on the amount of data and the number of partitions used.

Education becomes an important thing to advance a nation. Therefore, everyone must follow the education level. One of education level is early childhood education. KB & TK Permata Iman which was established in 2005 is a private educational institution and focus on early childhood education. In learning evaluation, KB & TK Permata Iman still use conventional method. The conventional method takes much time because teachers need to collect daily grade until the end of a semester for final grade calculation and prepare the results in grade book. The semester learning evaluation process can be shortened and simplified using a web-based academic assessment management information system. The system can store, directly perform calculations when teachers add studentsâ€™ grade and make grade book from saved grade. From the testing result, the time efficiency increased to 94.94% when evaluating semester learning using the system and it can help the teacher to save time and do another task.

Decline in quality caused by daily use of facilities and infrastructure owned by an organization will certainly disrupt its function in supporting the performance of the organization. The solution that came from the research that has been conducted before is to develop android applications called Infiremis (Infrastructure and Facility Reporting Management Information System), that can be used to report damage to facilities and infrastructure and to track the status reporting. This android application was developed to be used by students, lecturers and staffs of Faculty of Computer Science Brawijaya University which those users has different background persona. Therefore, the usability of this android application need be tested to find out the value of effectiveness, efficiency and satisfaction of the application to fulfill its purpose. This research was conducted mainly to discover the result of usability testing towards the android application of infrastructure and facility reporting management information system. Based on Usability Testing that has been done show that the level of effectiveness and satisfaction of Infiremis respectively is 97,14% and 89,7%, whereas for the efficiency score is 89,9%.

Web-based Application for Visual Representation of Learners' Problem-Posing Learning Pattern Supianto, Ahmad Afif; Wicaksono, Satrio Agung; Bachtiar, Fitra A.; Herlambang, Admaja Dwi; Hayashi, Yusuke; Hirashima, Tsukasa

Studentsâ€™ learning process analysis normally involves massive amount of data. This study explores the pattern and relationship of studentsâ€™ learning process data in an interactive learning media to identify their learning process patterns to ease the needs of sophisticated data analysis for class instructors and educational researchers. This study focuses on the development of a web-based software application that creates a visual representation of studentsâ€™ learning process in a learning media. The result of this software is a visualization of studentsâ€™ activity sequence. This result is then used to infer studentsâ€™ learning patterns as well as identifying their learning behavior and to create a better feedback via the learning instructors. As a case study, this research uses the data log of Monsakun, a digital learning environment that focuses on the subject of mathematic for grade school students on the topic of arithmetic using story-based question and problem-posing approach. Investigation result shows four distinct learning activity patterns which are: smart pattern, adventure pattern, peer pattern and cyclic pattern. Each pattern requires different feedback to optimize learning progression, by using this web-based application, appropriate feedback to specific learning pattern is then applied to each student based on its learning activity pattern.

Stress among university students negatively impacts their academic progress and mental health. Early detection is crucial for targeted intervention. This research designs and evaluates a machine learning model using the XGBoost algorithm to predict stress among undergraduate students of Information Technology Education at Universitas Brawijaya. Utilizing the CRISP-DM methodology, the study processes data from the DASS-42 questionnaire and academic records. The workflow included data pre-processing to handle missing values and class imbalance, followed by model training and evaluation. Six scenarios tested prediction targets (five-level multi-class and binary ‘Normal’ or ‘Stress’), data handling, and hyperparameter tuning. Results indicate that the binary classification model was significantly superior. The best model, utilizing original data and default parameters, achieved an accuracy of 97.87%. Evaluation proved its reliability, achieving 100% recall for the ‘Stress’ class, ensuring no at-risk cases were missed (0 False Negatives). Feature importance analysis identified Mother’s Education as the dominant predictor. The research output includes a functional dashboard prototype equipped with LIME interpretation for individual case analysis.
