Journal Innovations Computer Science Volume 4 Issue 2 published in November 2025 features thirty research studies exploring artificial intelligence, cybersecurity, Internet of Things, and digital transformation across multiple sectors. Machine learning applications include sentiment analysis using Naïve Bayes and K-Nearest Neighbor algorithms for e-commerce reviews, government performance evaluation, and social media discourse analysis. Cybersecurity research addresses Midtrans Payment Gateway DDoS protection, network redundancy through HSRP and VRRP protocols, and AWS-based Defense in Depth architecture for small business security. IoT innovations encompass automated household water monitoring, chicken coop temperature regulation using DHT11 sensors, and NodeMCU ESP8266-powered plant watering systems. Computer vision advances through YOLOv8-based rose classification, cryptographic hash-secured face recognition, and HOG-algorithm waste identification platforms. Digital service development includes web-based logistics management for Bintang Technic, thrifting marketplace platforms, and AcaraKita event organizer services. Research also covers Decision Tree models for customer satisfaction prediction, SMOTE-optimized neural networks for heart disease classification, heuristic evaluation of Tulungagung Portal interface, game-based learning at BQ Boarding School, SNMP enterprise network monitoring, edge computing for smart buildings, and low-light face recognition enhancement. These studies demonstrate practical technology applications in government services, commercial operations, education, and industrial automation throughout Indonesia.
