This is the Volume 4 of the Southeast Asian Journal of Science and Technology, featuring research that spans education, technology, business, environment, and community development in the Philippines and beyond. The articles explore practical tools for beginning researchers, quality of service in commercial banks, and professional development through action research for senior high school teachers. Technology-focused studies include Arduino-based door security and vehicle accident alert systems, QR code time-tracking applications, Android-based e-tourist maps, and ERP frameworks for SMEs. Other contributions examine sustainability in online merchandising, aquaculture, and fisheries, as well as socioeconomic factors influencing participation in mobile money. Educational research emphasizes brain-based and individualized instructional strategies, outcomes-based education implementation, mother tongue-based instruction, student study habits, and learning management systems. Community-centered and tourism studies highlight participation in mobile self-service banking, property card games, cultural integration, and Hamilton circuits of top tourist spots in Pangasinan. Volume 4 underscores applied research that addresses local challenges while promoting innovation, effective education practices, and sustainable community and economic development.
