Abstract:Academic achievement is a measure of students' learning outcomes, encompassing aspects of knowledge and skills. Academic performance serves as a crucial indicator in evaluating students' learning progress. MAS Al-Wasliyah…
h Petatal is committed to providing quality education but still faces limitations in applying technology to evaluate student learning. The current evaluation process relies on teachers' subjective assessments, which restricts the information about students' progress. Therefore, the implementation of machine learning is proposed as a solution to enhance objectivity in student learning evaluation through more effective data processing. The method used is the K-Means Clustering algorithm, which can group or classify data based on specific patterns. This study aims to evaluate the extent to which machine learning can process student learning evaluation data through the analysis results obtained from the clustering process, which are then used as benchmarks to improve the evaluation system and provide feedback for students needing improvement in their academic performance. The data used comprises students' grades from the odd semester of the 2024/2025 academic year, with a total of 210 data points. The clustering results produced three clusters: the "good" cluster with 60 students, the "average" cluster with 99 students, and the "low" cluster with 51 students.

. This study aims to optimize bread product sales by using the K-Means Clustering algorithm to analyze daily sales performance at Toko Roti Amin. The data used includes sales volume and transaction frequency for bread products, consisting of 356 data points. The results show that the bread products can be grouped into three clusters: 129 data in the “Good Sales” cluster, 28 data in the “Moderate Sales” cluster, and 199 data in the “Low Sales” cluster. These findings assist bakery owners in managing stock, production planning, and more targeted marketing strategies. Although there are limitations in using K-Means Clustering, such as dependence on the initial centroid selection, this study proves that applying this technique can enhance inventory management and maximize profit in the bakery business.

Serbangan. This research is an experimental study using a posttest-only design. The population consists of three 10th-grade classes, with two classes selected as samples: X IPA 1 and X Agama, chosen randomly using simple random sampling. The X Agama class was taught using the three-step interview method, while the X IPA 1 class served as the control group with conventional teaching methods. After the completion of the instruction, the post-test results showed an average score of 87.5 for the experimental class and 61.29 for the control class. The t-test results revealed a Thitung value of 79.15, exceeding the Ttabel value of 2.00, which means the null hypothesis (H0) can be rejected and the alternative hypothesis (Ha) accepted. This indicates that the three-step interview method has a significant effect on the ability to write observation report texts among 10th-grade students at Madrasah Aliyah Swasta Al-Washliyah Binjai Serbangan.
