Abstract

Penelitian ini bertujuan untuk menyelidiki upaya kepala sekolah dalam membina dan mengembangkan profesionalisme guru. Dalam upaya meningkatkan kualitas pendidikan, banyak lembaga pendidikan telah memberikan pelatihan dan pembinaan. Penelitian ini bertujuan untuk mengukur apakah pelatihan semacam itu memiliki dampak positif terhadap profesionalisme guru. Hasil penelitian menunjukkan bahwa guru yang mengikuti pembinaan dan pengembangan memiliki peningkatan yang signifikan dalam keterampilan mengajar dibandingkan dengan kelompok kontrol. Mereka lebih mampu merencanakan pembelajaran yang efektif, mengelola kelas dengan baik, dan berinteraksi dengan siswa secara positif. Selain itu, mereka juga memiliki tingkat motivasi yang lebih tinggi dalam mengajar. Temuan ini menunjukkan bahwa upaya yang dilakukan kepala sekolah dapat memiliki dampak positif yang signifikan pada keterampilan mengajar guru. Oleh karena itu, disarankan agar lembaga pendidikan terus mendorong dan menyediakan pembinaan dan pengembangan yang relevan dan bermanfaat bagi guru mereka. Hal ini dapat berkontribusi pada peningkatan kualitas pendidikan dan pengalaman belajar siswa.

Abstract

This research aims to design and build a web-based college major recommendation system for high school students focused on SMA Negeri 8 Medan using a hybrid C4.5–Naïve Bayes approach. The C4.5 algorithm is used for feature selection from report card grades and interest test results, while Naïve Bayes classifies majors based on the selected features. This research uses a quantitative approach because the main focus of this approach is on the analysis of numerical data generated by the model. Specifically, the research will measure evaluation metrics such as accuracy, precision, recall, and F1-score to objectively assess how effective the system is in providing major recommendations to students at SMA Negeri 8 Medan. The results of this research are that a web-based system has been successfully designed and developed using a hybrid approach of the C4.5 and Naïve Bayes algorithms where C45 is used in the feature selection stage to determine the most influential attributes (grades and interests) in determining majors, and the Naïve Bayes algorithm is used as the main classification model to predict majors based on the selected features.

Abstract

The best and qualified employees will make a company to be improved in its operations in the collection of pine resin to achieve the target. However, the constraints at PT INHUTANI V GM SUMBAGUT best employee award is still not optimal its implementation. Therefore, a system is needed that can assist the company in assessing the best employees optimally. Decision making to determine the best employee can be done by the company by assessing the performance that has been done by its employee at PT. INHUTANI V is influenced by several criteria, namely : Attendance, Teamwork, Colecction of the most pine sap, Responsibility, Sales of the most sap to the factory. This decision support system uses the Simple Additive Weighting (SAW) method where the decision-making process can be calculated based on the calculation of the weight of each criterion, so as to select the best employees in the company quickly.
