Abstract

This research is motivated by the absence of an information system concerning the placement of student internships. This is attributed to the diverse backgrounds of students at the H. Agus Salim Institute of Technology and Business (ITB), comprising three different classes. For regular morning students, internship placements can be tailored to their field of study. However, for evening students (regular two) and weekend students (regular three), who are individuals already employed in government institutions and private companies, determining suitable internship locations becomes challenging. This is because the tasks performed in these institutions and companies may not align with the academic disciplines studied by the students during their academic tenure. In the design of this internship information system, the researcher adopts the Incremental model, which is one of the models in the Software Development Life Cycle (SDLC). Functional suitability testing, compatibility testing, usability testing, and validity testing were conducted on the internship management information system. The test results, carried out by one expert, yielded a functional suitability score of 94%, categorized as excellent. The capability test, also conducted by one expert, resulted in a score of 80%, categorized as very good. Usability testing, conducted by seven experts, yielded a score of 80.6%. Validity testing, carried out by three validators, resulted in a score of 0.86, categorized as highly valid.

Abstract

This research is based on field findings through observations and interviews at SMKN 2 Padang Panjang, which revealed that the process of managing school fee relief scholarship acceptance data is still done manually. This condition causes slow data input processes, slows down administration, and increases the potential for errors in processing student data. Thus, the main focus of this research is to create a valid, practical and effective SPK design in determining scholarship acceptance. This research is a type of Research and Development (R&D) research, using the Analytical Hierarchy Process (AHP) method and the Agile development model. Based on the results of the validity test with 3 lecturers, the system obtained a score of 0.86, indicating a very high level of validity. The practicality test with 3 teachers obtained a score of 0.97, indicating that the system is easy to use. Meanwhile, the results of the effectiveness test with 22 students obtained a score of 0.87, indicating that this system is effective in supporting the scholarship recipient selection process. Unlike previous studies that generally only apply one decision-making method or use conventional development models, this study integrates AHP with an Agile approach to produce a system that is more accurate, practical, and adaptive to school needs. With these achievements, the developed decision support system is worthy of being used as a reliable and efficient tool in determining scholarship recipients at SMKN 2 Padang Panjang.

Abstract

This study aims to implement the C4.5 algorithm to build a model for predicting student success in database system courses in the Informatics and Computer Engineering Education study program at UIN Sjech M. Djamil Djambek Bukittinggi. Using the Knowledge Discovery in Database (KDD) approach, this study includes the stages of data selection, cleaning, transformation, modeling, and evaluation. Secondary data from the academic information system of students enrolled from 2018 to 2023 included 1,177 entries, which after cleaning resulted in 1,030 valid data. Predictor attributes consisted of academic factors such as Algorithm Logic scores, 1st semester Grade Point Average (GPA), attendance, and credit load, as well as non-academic factors such as gender and UKT (Tuition Fee Category). The target variable was student success status. Modeling was performed using Altair RapidMiner 2025 software with the C4.5 algorithm, resulting in a decision tree model. Evaluation showed an accuracy of 82.10%, recall of 69.58%, and precision of 62.51%, indicating the algorithm's effectiveness in classifying students as potentially successful or unsuccessful. This model identifies the most influential attributes, both academic and non-academic, on student success. Overall, the application of the C4.5 algorithm supports Educational Data Mining (EDM) in higher education, helping study programs improve the quality of learning and the effectiveness of data-based academic interventions.
