Abstract
The Constitution guarantees every citizen equal treatment before the law and access to non-discriminatory public services. However, members of the public are often unaware of these rights and the procedures for asserting them when they experience unfair treatment by public service officials. This community service program aimed to raise public awareness of constitutional rights in accessing fair and non-discriminatory public services in the Menteng area of Medan City. The program was conducted on August 19, 2026, by three lecturers specializing in Constitutional Law and attended by 40 participants. The materials covered constitutional rights to equal treatment, the principles and standards of public service under Law No. 25 of 2009, and complaint mechanisms available through public service providers and the Ombudsman of the Republic of Indonesia. Evaluation was conducted through pre-tests and post-tests, case study simulations, and a satisfaction survey. The participants’ average scores increased from 45 to 90, with an N-gain of 0.82 (high category); 38 participants (95%) demonstrated improved scores, and no participants experienced a decline in their scores. In the case study simulation, participants’ understanding improved, as indicated by an increase in correct answers from 30% to 90%. All participants reported being satisfied or very satisfied with the program. These findings indicate that case-based education helps the public develop a practical understanding of their constitutional rights, including identifying the information they should request, the evidence they need to retain, and the complaint channels they can pursue.
