Correctional clients who receive integration programs are required to report regularly as part of guidance and supervision by the Correctional Center (Bapas). The wide working area of Bapas Class II Purwokerto creates geographical and transportation barriers for some clients, making the Griya Abhipraya Kota Lama Banyumas Bapas Post an important decentralized service. This study aims to analyze the effectiveness of Bapas Post services in supporting compulsory reporting compliance and to identify supporting and inhibiting factors. The study employed a qualitative phenomenological approach. Data were obtained through observation, semi-structured interviews, and documentation involving seven participants consisting of the Head of Bapas Class II Purwokerto, two Correctional Guidance Officers, and four adult correctional clients. Data were analyzed through data reduction, data presentation, interpretation, conclusion drawing and verification, supported by triangulation. The findings show that the Bapas Post service generally operates effectively. Based on Subagyo's effectiveness indicators, the service has targeted clients who need closer access, socialization has been conducted through Correctional Guidance Officers, initial assessments, registration, social media, WhatsApp, and direct communication, while program objectives are supported by reduced travel distance, time, and cost and more intensive communication between officers and clients. Monitoring is conducted through attendance books, guidance cards, digital systems, officer communication, managerial monitoring, monthly evaluation, and follow-up for clients who are late or absent. Supporting factors include location accessibility, officer communication and commitment, friendly service, communication flexibility, and monitoring systems. Inhibiting factors include limited facilities, unstable internet connectivity, transportation barriers for some clients, conflicts between reporting schedules and work, and distribution of Correctional Guidance Officers.
