Abstract

Penelitian ini bertujuan untuk mengetahui tingkat minat siswa kelas 1 SMK Putra Jaya Stabat terhadap kegiatan ekstrakurikuler sepak bola, serta menganalisis faktor-faktor yang memengaruhinya. Untuk memperdalam pemahaman terhadap penerimaan siswa terhadap sistem informasi yang mendukung kegiatan ekstrakurikuler, penelitian ini menggunakan pendekatan Technology Acceptance Model (TAM). Model ini digunakan untuk mengukur pengaruh Perceived Usefulness dan Perceived Ease of Use terhadap minat dan perilaku siswa dalam mengikuti serta memanfaatkan sistem informasi pendukung ekstrakurikuler, seperti jadwal digital, absensi daring, atau komunikasi tim secara online. Sampel penelitian berjumlah 74 siswa, ditentukan melalui rumus Slovin dari total populasi 280 siswa. Data dikumpulkan melalui angket skala Likert dan dianalisis secara kuantitatif deskriptif. Hasil penelitian menunjukkan bahwa sebagian besar siswa menunjukkan minat tinggi terhadap ekstrakurikuler sepak bola, serta bersikap positif terhadap penggunaan sistem informasi pendukung. Faktor internal seperti motivasi pribadi dan hobi, serta faktor eksternal seperti kemudahan penggunaan sistem dan dukungan sosial, berkontribusi terhadap tingginya minat tersebut. Temuan ini dapat menjadi acuan bagi sekolah dalam mengembangkan sistem informasi ekstrakurikuler yang efektif dan sesuai dengan kebutuhan siswa.

Abstract

The accurate targeting of social assistance recipients is a critical challenge in public policy implementation, particularly in efforts to reduce poverty and social inequality. This study aims to apply the Decision Tree C4.5 algorithm to determine the eligibility of social assistance beneficiaries based on socio-economic data. The research employs a quantitative approach using data mining techniques, where data preprocessing, model construction, and performance evaluation are conducted systematically. The C4.5 algorithm is selected due to its ability to handle numerical and categorical data and to produce interpretable decision rules. The results indicate that the proposed model achieves a high classification performance, with income level emerging as the most influential attribute, followed by household dependents and housing conditions. The generated decision tree provides clear and transparent rules that facilitate understanding of eligibility determination. These findings demonstrate that the C4.5 algorithm is effective not only in terms of accuracy but also in supporting explainable decision-making processes. The study concludes that integrating Decision Tree C4.5 into social assistance management can enhance objectivity, transparency, and policy effectiveness. This research contributes to the development of data-driven decision support systems in the public sector and offers practical insights for improving the accuracy of social assistance distribution.

Abstract

This research aims to analyze the learning performance of vocational high school students in Informatics subjects thru the integration of Generative AI (Gemini) with the K-Means Clustering algorithm, an approach that is still rarely applied in the Indonesian educational context. The research data includes 28 students, consisting of 8 males and 20 females, whose performance was analyzed based on assignment, quiz, and exam scores. The clustering results yielded three main performance groups: high, medium, and low clusters. Gemini integration helps accelerate the process of interpreting the clustering results and provides a deeper understanding of students' learning patterns. The research findings indicate that the combination of generative AI and cluster analysis can generate more accurate insights to support the implementation of adaptive learning and data-driven decision-making by teachers. Additionally, this study contributes to the development of learning analytics at the vocational education level, while also opening opportunities to implement more personalized learning strategies. Further research could expand the data scope, test other clustering algorithms, and develop an analytics dashboard to facilitate data utilization by educational institutions.
