Ratu Mas Zahra Nuraini Nawang Wulan, Naya Hasna Ainayya, Rika Agustina Ritonga, Suroya Lailata Hafilah

This study investigates the effect of empathy on elementary school students' academic engagement by examining the mediating and moderating roles of social support. Employing a quantitative survey design, the study involved 249 students from four elementary schools selected through stratified random sampling. Data were collected using questionnaires that assessed three primary constructs: empathy, social support, and student engagement. Data analysis was performed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS version 4. The findings reveal that empathy significantly and positively influences both student engagement and perceived social support. However, social support does not have a direct significant impact on student engagement and fails to mediate the relationship between empathy and engagement. Interestingly, empathy was found to moderate the relationship between social support and engagement negatively, indicating that students with high levels of empathy tend to participate actively in learning regardless of external support. These results highlight the critical role of empathy in fostering student engagement and support the integration of social-emotional learning strategies in elementary education settings.

Perbandingan Kualitas Clustering antara Algoritma K-Means dan DBSCAN dalam Segmentasi Pelanggan Produk Digital

Muhamad Alip, Fani Laraswati, Ahwa Ramadan

Segmentasi pelanggan merupakan strategi penting dalam menganalisis pola konsumsi dan perilaku pengguna dalam berbagai sektor industri, termasuk layanan digital. Dengan kemajuan teknologi dan meningkatnya volume data yang tersedia, organisasi kini membutuhkan metode analisis data yang mampu mengelompokkan pelanggan secara efisien dan bermakna. Penelitian ini bertujuan untuk melakukan perbandingan antara dua algoritma clustering populer, yaitu K-Means dan DBSCAN (Density-Based Spatial Clustering of Applications with Noise) dalam konteks segmentasi pelanggan berbasis atribut numerik yang diperoleh dari data interaksi dan transaksi digital. K-Means, yang bersifat partisional dan bergantung pada jumlah klaster yang ditentukan di awal, dievaluasi melalui pendekatan Elbow Method dan Silhouette Score untuk menentukan nilai K yang optimal. Di sisi lain, DBSCAN yang berbasis kepadatan tidak memerlukan penentuan jumlah klaster sebelumnya dan mampu mengidentifikasi outlier atau noise secara otomatis, namun sangat bergantung pada pemilihan parameter epsilon (ε) dan minimal sampel. Data yang digunakan dalam penelitian ini adalah data pelanggan dari sebuah layanan digital, terdiri dari atribut seperti umur pengguna, frekuensi interaksi, dan jumlah pengeluaran. Seluruh data melalui proses pembersihan, normalisasi, dan rekayasa fitur sebelum dilakukan klasterisasi. Hasil penelitian menunjukkan bahwa algoritma K-Means menghasilkan lima klaster utama dengan distribusi yang lebih merata, sedangkan DBSCAN hanya membentuk satu klaster dominan dengan sejumlah data yang diklasifikasikan sebagai noise, menandakan adanya perbedaan sensitivitas terhadap distribusi data. Evaluasi kualitatif dilakukan menggunakan metrik Silhouette Score yang memperlihatkan nilai 0.32 untuk K-Means dan nilai yang sangat rendah untuk DBSCAN, menunjukkan kualitas cluster yang kurang optimal dalam skenario ini. Penelitian ini menegaskan bahwa tidak ada satu algoritma clustering yang secara universal unggul, melainkan pemilihannya sangat bergantung pada karakteristik data, kebutuhan segmentasi, dan tujuan analisis. Implikasi praktis dari studi ini adalah pentingnya memahami kekuatan dan keterbatasan masing-masing algoritma dalam konteks implementasi nyata, khususnya dalam pengelolaan strategi personalisasi dan retensi pelanggan berbasis data.
