Mobile Application for Citizen Engagement with Urban Patrols in Cajamarca

Abstract

pre-experimental design with pre- and post-tests, using a convenience sample of 60 participants (40 citizens and 20 patrol members). The app, developed with SCRUM, Android Studio, Kotlin, and Firebase, includes geolocation, multimedia evidence, severity classification, real-time notifications, and report tracking. The results show significant improvements: response time reduced from 45 to 15 minutes (67%), response level from 1 to 4 points, report completeness from 40% to 90%, and satisfaction from 2 to 4.2 points, with high usability confirmed by the System Usability Scale (SUS). These findings confirm the positive effect of the tool on collaborative communication, reducing traditional barriers and strengthening community safety in contexts with limited resources, accepting the alternative hypothesis and demonstrating the value of citizen-centered digital solutions for organizations such as Rondas Urbanas.
