Abstract

Era digital menuntut penguasaan keterampilan teknologi informasi sebagai bagian dari literasi dasar. Pengabdian Kelompok Kuliah Kerja Nyata (KKN) Tematik di Desa Margalaksana ini bertujuan untuk meningkatkan literasi digital siswa Sekolah Menengah Pertama (SMP) Negri 1 Cilawu melalui pelatihan penggunaan software dasar seperti Microsoft Word, Excel, Canva, dan pengenalan pemrograman dasar. Program pelatihan ini dirancang untuk membantu siswa mengembangkan keterampilan yang esensial dalam dunia pendidikan dan kerja yang semakin digital. Metode yang digunakan meliputi ceramah, demonstrasi, dan praktik langsung dengan pendekatan partisipatif, di mana siswa dilibatkan secara aktif dalam proses belajar. Perolehan atas program ini memperlihatkan terdapat kenaikan signifikan dalam pemahaman dan keterampilan siswa terhadap penggunaan software yang diajarkan. Siswa mampu membuat dokumen teks, lembar kerja, desain grafis sederhana, serta memahami konsep dasar pemrograman. Program ini pula diekspektasikan mampu mendorong siswa guna terus mengeksplorasi teknologi digital, yang pada akhirnya berkontribusi terhadap peningkatan kualitas pendidikan di SMP Negri 1 Cilawu. Kendala yang dihadapi selama pelaksanaan meliputi keterbatasan sarana prasarana dan variasi tingkat kemampuan siswa dalam memahami materi. Namun, melalui bimbingan intensif dan pendekatan yang adaptif, program ini berhasil mencapai tujuannya.

Abstract

The increasing availability of transactional data in the retail sector provides opportunities to support data-driven managerial decision-making. This study aims to segment supermarket sales transactions using the K-Means clustering method to identify meaningful transaction patterns that support retail decision-making. A publicly available supermarket transaction dataset was analyzed using selected numerical attributes representing purchase quantity, transaction value, and customer rating. To ensure reliable and interpretable clustering results, data standardization was applied, and the optimal number of clusters was determined using a combined validation strategy comprising the Elbow Method and the Silhouette Score. The results indicate that three distinct transaction segments were identified, characterized by similar purchase quantities but differing transaction values and customer satisfaction levels. Principal Component Analysis visualization confirms that the resulting clusters are well separated and interpretable. The findings demonstrate that integrating systematic cluster validation with interpretable cluster analysis provides practical insights for retail managers in designing targeted marketing strategies, improving customer satisfaction, and supporting inventory and promotional decision-making.
