Abstract

Pertumbuhan pesat e-commerce di Indonesia mendorong perusahaan untuk memahami karakteristik konsumen secara lebih mendalam guna meningkatkan strategi pemasaran. Penelitian ini bertujuan untuk mengelompokkan konsumen e-commerce berdasarkan pola pembelian menggunakan metode K-Means Clustering. Segmentasi dilakukan dengan mempertimbangkan tiga variabel utama, yaitu frekuensi pembelian, nilai transaksi, dan waktu pembelian. Data transaksi konsumen diolah dan dianalisis untuk menemukan pola-pola yang tersembunyi, kemudian ditentukan jumlah klaster optimal menggunakan metode Elbow. Hasil penelitian menunjukkan bahwa konsumen dapat dikelompokkan ke dalam lima segmen yang memiliki karakteristik perilaku belanja yang berbeda-beda, mulai dari konsumen bernilai tinggi dan aktif, hingga konsumen pasif dengan nilai transaksi rendah. Segmentasi ini memberikan wawasan penting bagi pelaku e-commerce dalam menyusun strategi pemasaran yang lebih tepat sasaran sesuai dengan karakter masing-masing segmen. Kesimpulan dari penelitian ini menunjukkan bahwa penerapan K-Means Clustering efektif dalam membantu memahami perilaku konsumen dan dapat dijadikan dasar pengambilan keputusan bisnis yang lebih strategis.

Abstract

The “Love Your Country from an Early Age!” program was implemented at SMPN 2 Kota Bangun as a strategic effort to strengthen students’ national awareness in the face of globalization, which often threatens national identity. This community service activity targeted ninth-grade students and student council members, aiming to instill fundamental national values through interactive learning approaches. The methods applied included thematic lectures supported by multimedia presentations, small group discussions, and educational quizzes designed to foster active participation and collaborative learning. Evaluation was conducted using pre-tests, post-tests, and direct observation of student engagement throughout the program. The results demonstrated a significant improvement in students’ understanding of national values. The average pre-test score of 62.5 increased to 84.3 in the post-test, with more than 80% of participants correctly answering basic questions related to Pancasila, the 1945 Constitution, Bhinneka Tunggal Ika, and the Unitary State of the Republic of Indonesia (NKRI). In addition to cognitive gains, students exhibited positive attitudes such as enthusiasm, collaboration, and the ability to connect the material with everyday practices, including respecting diversity and maintaining the school environment. These findings confirm that interactive learning is an effective approach to instilling national values and fostering concrete expressions of patriotism among junior high school students. The program provides a practical model for character education that can be replicated in other schools, thereby contributing to the preservation of Indonesia’s national identity and values in the era of globalization.
