Abstract

Kegiatan kemahasiswaan berperan penting dalam pengembangan kompetensi mahasiswa, namun tingkat keaktifan pada berbagai aktivitas seperti organisasi, seminar, kepanitiaan, lomba, dan pengembangan diri menunjukkan variasi yang signifikan sehingga diperlukan pendekatan berbasis data untuk mengidentifikasi pola keterlibatan secara lebih objektif. Penelitian ini menerapkan K-Means Clustering pada data 100 responden mahasiswa UINSU yang diperoleh melalui Google Forms, melalui tahapan preprocessing, konversi skala ordinal, serta analisis menggunakan Python (Google Colab). Jumlah cluster optimal ditentukan menggunakan metode Elbow berbasis Within Cluster Sum of Squares (WCSS). Hasil penelitian menunjukkan terbentuk tiga cluster (k=3), yaitu C0 (30 mahasiswa) dengan karakteristik aktif organisasi dan kepanitiaan yang ditandai skor panitia 2.43 dan organisasi 1.63, C1 (38 mahasiswa) sebagai kelompok sangat aktif/multitalenta dengan dominasi pengembangan diri 2.03 dan lomba 1.76, serta C2 (32 mahasiswa) sebagai kelompok kurang aktif dengan skor terendah pada organisasi 0.31 dan lomba 0.47. Visualisasi PCA memperkuat pemisahan cluster yang terbentuk, sehingga menunjukkan bahwa K-Means efektif dalam mengungkap heterogenitas tingkat keaktifan mahasiswa dan dapat digunakan sebagai dasar pengambilan keputusan berbasis data dalam pengelolaan program kemahasiswaan.Kata Kunci— Kegiatan Kampus, Keaktifan Mahasiswa, Klasterisasi; K-Means, Segmentasi ABSTRACT Student activities play a crucial role in developing students’ competencies; however, participation levels in various activities—such as student organizations, seminars, event committees, competitions, and personal development—show significant variation, necessitating a data-driven approach to identify patterns of engagement more objectively. This study applied K-Means Clustering to data from 100 UINSU student respondents collected via Google Forms, through stages of preprocessing, ordinal scale conversion, and analysis using Python (Google Colab). The optimal number of clusters was determined using the Elbow method based on the Within Cluster Sum of Squares (WCSS). The results indicate the formation of three clusters (k=3): C0 (30 students) characterized by active involvement in organizations and committees, marked by a committee score of 2.43 and an organizational score of 1.63; C1 (38 students) as a highly active/multitalented group dominated by personal development (2.03) and competitions (1.76), and C2 (32 students) as a less active group with the lowest scores in organizational activities (0.31) and competitions (0.47). PCA visualization reinforces the separation of the formed clusters, indicating that K-Means is effective in revealing the heterogeneity of student activity levels and can serve as a basis for data-driven decision-making in the management of student programs. Keywords— Campus Activities, Clustering, K-Means, Segmentation, Student Activity

Abstract

Abstrak—Discord merupakan platform komunikasi digital yang digunakan untuk berbagai kebutuhan seperti komunitas, hiburan, pembelajaran, dan komunikasi daring. Perbedaan pola penggunaan Discord menyebabkan munculnya karakteristik pengguna dan tingkat kepuasan yang berbeda sehingga diperlukan proses segmentasi pengguna. Penelitian ini bertujuan untuk melakukan segmentasi pengguna Discord menggunakan metode K-Means Clustering berdasarkan pola penggunaan dan tingkat kepuasan pengguna. Dataset penelitian diperoleh melalui penyebaran kuesioner daring kepada 200 responden. Proses penelitian meliputi preprocessing data, pengujian reliabilitas menggunakan Cronbach Alpha, transformasi data, normalisasi menggunakan StandardScaler, penentuan jumlah cluster menggunakan Elbow Method, serta evaluasi model menggunakan Silhouette Score. Seluruh proses pengolahan data dilakukan menggunakan Google Colab berbasis Python. Hasil pengujian reliabilitas memperoleh nilai Cronbach Alpha sebesar 0,861 yang menunjukkan bahwa data penelitian memiliki tingkat konsistensi yang baik. Hasil penelitian menunjukkan bahwa jumlah cluster optimal diperoleh pada K=2 dengan nilai Silhouette Score sebesar 0,33. Hasil clustering berhasil membagi pengguna Discord ke dalam dua kelompok utama, yaitu kelompok pengguna aktif dengan frekuensi penggunaan, interaksi sosial, dan tingkat kepuasan yang tinggi serta kelompok pengguna moderat dengan frekuensi penggunaan dan tingkat kepuasan yang relatif lebih rendah. Visualisasi menggunakan Principal Component Analysis (PCA) menunjukkan persebaran cluster yang cukup baik.Kata Kunci— Discord, K-Means Clustering, Segmentasi Pengguna, Silhouette ScoreAbstract—Discord is a digital communication platform used for various purposes such as community activities, entertainment, learning, and online communication. Differences in Discord usage patterns lead to varying user characteristics and satisfaction levels, making user segmentation necessary. This study aims to segment Discord users using the K-Means Clustering method based on usage patterns and user satisfaction levels. The research dataset was obtained through an online questionnaire distributed to 200 Discord users. The research process included data preprocessing, reliability testing using Cronbach Alpha, data transformation, normalization using StandardScaler, determining the optimal number of clusters using the Elbow Method, and model evaluation using the Silhouette Score. All data processing was conducted using Python-based Google Colab. The reliability test obtained a Cronbach Alpha value of 0.861, indicating that the research data had good consistency. The results showed that the optimal number of clusters was obtained at K=2 with a Silhouette Score of 0.33. The clustering process successfully divided Discord users into two main groups, namely active users with high usage frequency, social interaction, and satisfaction levels, and moderate users with relatively lower usage frequency and satisfaction levels. Visualization using Principal Component Analysis (PCA) showed a fairly good distribution of the clusters.Keywords— Discord, K-Means Clustering, User Segmentation, Silhouette Score

Abstract

Penyakit tanaman cabai dapat menyebabkan penurunan produksi yang signifikan, sehingga membuat keberlanjutan pertanian dan pangan. Penelitian ini mengembangkan sistem untuk mengkategorikan daun cabai menggunakan Gray Level Co-occurrence Matrix (GLCM) untuk ekstraksi tekstur dan K-Nearest Neighbors (KNN) untuk klasifikasi. Data citra daun cabai yang digunakan meliputi jenis penyakit virus mosaik cabai, layu fusarium, virus kuning, dan bercak daun. Proses tersebut meliputi pemilihan citra, ekstraksi fitur menggunakan GLCM, dan klasifikasi menggunakan KNN. Hasil penelitian menunjukkan bahwa rasio tersebut dapat mencapai hingga 90%, tergantung pada parameter K. Temuan ini penting bagi dunia pertanian, karena dapat menjadi dasar pengembangan sistem deteksi dini berbasis teknologi, sehingga petani dapat mengambil tindakan lebih cepat dan efektif dalam mengendalikan penyebaran penyakit. Implementasi metode ini memiliki potensi besar untuk meningkatkan efisiensi pengelolaan tanaman, mengurangi kerugian ekonomi, dan mendukung pertanian berkelanjutan.Kata kunci: Penyakit daun cabai, K-Nearest Neighbor, GLCM, Klasifikasi. ABSTRACT Chili plant diseases can cause significant production declines, thus making the sustainability of agriculture and food. This study develops a system to categorize chili leaves using Gray Level Co-occurrence Matrix (GLCM) for texture extraction and K-Nearest Neighbors (KNN) for classification. The chili leaf image data used includes types of chili mosaic virus diseases, fusarium wilt, yellow virus, and leaf spots. The process includes image selection, feature extraction using GLCM, and classification using KNN. The results of the study show that the ratio can reach up to 90%, depending on the K parameter. This finding is important for the world of agriculture, because it can be the basis for the development of a technology-based early detection system, so that farmers can take faster and more effective action in controlling the spread of disease. The implementation of this method has great potential to improve the efficiency of crop management, reduce economic losses, and support sustainable agriculture. Keywords: Chile leaf disease, K-Nearest Neighbor, GLCM, Classification.
