Abstract

Penelitian ini bertujuan untuk menganalisis akurasi model prediksi kepuasan mahasiswa/i terhadap layanan perpustakaan STIKOM Tunas Bangsa menggunakan metode C4.5. Layanan perpustakaan yang berkualitas merupakan faktor penting dalam menunjang keberhasilan akademik mahasiswa/i. Penelitian ini bertujuan untuk menganalisis tingkat kepuasan mahasiswa/i terhadap layanan perpustakaan menggunakan metode C4.5, sebuah algoritma pohon keputusan yang populer untuk klasifikasi. Dengan pendekatan ini, diharapkan dapat diukur tingkat akurasi kepuasan dan mengidentifikasi faktor-faktor utama yang memengaruhinya, sehingga perpustakaan dapat meningkatkan kualitas layanan sesuai dengan kebutuhan pengguna.i. Data yang digunakan dalam penelitian ini diambil dari survei kepuasan mahasiswa/i terhadap berbagai aspek layanan perpustakaan, seperti ketersediaan koleksi, fasilitas, pelayanan staf, dan kenyamanan ruang baca. Data tersebut kemudian diolah dan dianalisis menggunakan metode C4.5 untuk membangun model prediksi. Hasil analisis menunjukkan bahwa metode C4.5 mampu memberikan akurasi yang cukup tinggi dalam mengukur kepuasan mahasiswa/i, dengan tingkat akurasi yang dihasilkan mencapai persentase yang signifikan. Penelitian ini memberikan kontribusi penting dalam pengembangan model prediksi kepuasan mahasiswa/i yang dapat digunakan sebagai acuan dalam meningkatkan kualitas layanan perpustakaan di STIKOM Tunas Bangsa.

Abstract

Purpose–This study aims to measure the effectiveness of implementing Project-Based Learning (PjBL) in improving students' speaking skills.Methodology – This study uses a quantitative pre-test and post-test design. Researchers will compare students' speaking skill scores before (pre-test) and after (post-test) using the Project-Based Learning (PjBL) to determine whether there is a significant improvement. The quantitative data will analyse used SPSS to measure the experimental and control classes.Findings – This study show that the experimental class had a higher average score (75.74) than the control class (61.32). The Sig. (2-tailed) is less than 0.05; the difference between the means is statistically significant. There is a statistically significant difference between the means of the experimental and control classes.Contribution – The increase in scores from pre-test to post-test is empirical evidence that project-based learning is an effective learning method for improving student learning outcomes while developing the various skills required for future success.
