Abstract

The percentage of stunting toddlers in Sumedang Regency is the highest compared to other nutritional problems. Stunting imposes a significant risk to the future quality of human resources. This study explores the performance of the Support Vector Machine (SVM) algorithm in predicting the stunting status of toddlers in Tanjungmedar Subdistrict, the region with the highest incidence of stunting cases in Sumedang Regency in 2020. The testing uses RapidMiner software and applies the Synthetic Minority Oversampling Technique (SMOTE) to overcome the imbalanced dataset so that the resulting performance can be optimized. Accuracy, precision, recall, and F1-score are measured in performance evaluation using a confusion matrix. The findings demonstrate that SMOTE might adjust the distribution of target classes in the dataset to maximize the SVM algorithm's performance. At the start of the test, the SVM model produced an accuracy of 85.10%. After applying SMOTE, the accuracy of the SVM model increased to 89.08%. The F1-score also increased for each class, except for the Normal class, which decreased slightly. These results demonstrate the suitability of SVM combined with SMOTE for health-related multiclass classification tasks, especially in imbalanced public health datasets, contributing to the advancement of applied machine learning in healthcare informatics.

Abstract

Cybersecurity threats are increasingly complex and widespread, posing significant risks to individuals and organizations. However, many studies tend to address the technological or behavioral aspects separately. The study uses a survey-based quantitative approach using PLS-SEM to analyze key factors that influence cybersecurity awareness, including demographics, training, psychological bias, and organizational culture. The findings suggest that several constructs-such as threat awareness, perceived risk, and education-significantly predict cybersecurity awareness and behaviour. Notably, the model yields an R² value of up to 0.703 with a strong path significance (p < 0.05), which underscores the robustness of the relationship. This study offers an integrated perspective on cybersecurity by bridging the psychological, educational, and organizational dimensions. It highlights cybersecurity awareness as a mediating construct that links upstream factors to secure user behavior-a relational structure that has not been explored in previous research.

Abstract

Layanan pengaduan pelanggan merupakan salah satu elemen penting dalam menjaga kualitas layanan suatu perusahaan. Efisiensi dalam menangani pengaduan pelanggan merupakan elemen kunci dalam mempertahankan loyalitas pelanggan, terutama bagi perusahaan penyedia jasa seperti IMASNET Darmaraja. Saat ini, pengelolaan pengaduan pelanggan dilakukan secara manual, yang sering menyebabkan keterlambatan dalam merespons keluhan dan kurangnya transparansi. Penelitian ini bertujuan untuk merancang dan membangun aplikasi layanan pengaduan pelanggan berbasis web yang memungkinkan pelanggan menyampaikan pengaduan, memeriksa statusnya, dan menerima notifikasi secara real-time. Studi ini melibatkan 50 pengguna layanan yang tersebar di 4 RT di Desa Darmajaya, Kecamatan Darmaraja, Kabupaten Sumedang, Jawa Barat, dengan bandwidth internet sebesar 150 Mbps yang didistribusikan di area tersebut. Metode Pengembangan model Waterfall digunakan dalam penelitian ini. Hasil evaluasi menunjukkan aplikasi berbasis web ini mampu mempercepat proses pengelolaan pengaduan hingga 50% dibandingkan metode manual, serta memastikan distribusi bandwidth yang lebih optimal.
