Community service activities (PKM) are an integral part of the Tri Dharma, namely Teaching, Research and Community Service. This PKM activity is carried out by Lecturers routinely every semester which aims to contribute to the community in the application of knowledge needed to face very dynamic developments and changes in all aspects of life. The synergy and collaboration of academics and the community are expected to have a positive impact on both society and the University. Community service activities are inseparable from the other Two Dharmas, and involve all Academics, namely lecturers, students, education staff and alumni. Through PKM, the academic community can be present in the midst of society in order to help with various problems faced by the community. The community service activity (PKM) carried out in the even semester of the 2023/2024 academic year was the installation of a hole guard rail (Hole Guard Rail) for inspection or inspection of the lower part of the Test Vehicle which is often referred to as the Undercarriage of Vehicles. The motor vehicle test hole or tunnel is one of the facilities at the Motor Vehicle Testing UPT (PKB). The purpose of installing this Safety Rail is to implement Safety First, namely preventing cars or test vehicles from falling into holes or test tunnels and ensuring that services to the public using the service can run smoothly as expected. The construction of this Safety Rail uses two types of UNP profile steel (U channel), namely U channel 100 and 50. U channel 100 is for the safety rail or barrier while channel 50 is for the support pole or support for the Safety Rail. This steel construction is glued or tied with an Electric arc welding system (SMAW). The total cost of this construction is borne by the Head of UPT PKB, Maros Regency.

The primary focus of this research was to create a Smart Count of Vehicle Loading Prototype for ships, with an emphasis on monitoring and tallying vehicles boarding and disembarking from ships based on their weight. Microcontrollers, such as the ESP32, were utilized for the counting process and to determine if the ship's cargo weight exceeded its maximum capacity. The main objective was to prevent overloading on ships, which could lead to accidents during voyages or while vehicles were being loaded onto the ship. To achieve this goal, weight and distance sensors were installed on the ship and controlled by the microcontroller, allowing for accurate monitoring of the quantity and categories of vehicles being loaded. After designing and testing this prototype device, it has become a new technological innovation that makes monitoring the weight and quantity of cargo on ships easier and more efficient. This is supported by the fact that each sensor's readings can work well with an average error rate below 2%. Additionally, the maximum communication range between the Blynk IoT application and the ship system can reach up to 20 meters.

This study explores how public service innovations in motor vehicle testing, based on Regional Public Service Agencies (BLUD), can improve road safety governance. In regions with rapidly growing motor vehicle populations, inadequate roadworthiness controls contribute to high traffic accident risks. While Indonesia has a regulatory framework for motor vehicle testing, service delivery remains largely administrative and lacks a strong focus on road safety. The study aims to assess how public service innovations can enhance road safety governance through local government-managed vehicle testing based on BLUD. Using a qualitative case study approach, data were collected through in-depth interviews, observations, and document analysis involving local government officials, testing technicians, and service users. Thematic and interpretive data analysis identified governance dimensions that influence service effectiveness. The study finds that road safety governance improvement relies on four main capacities: relational, structural, resource, and adaptive. Although BLUD-based management offers flexibility for service innovation, its implementation has not fully aligned with road safety goals. Challenges remain in public trust, cross-agency coordination, resource availability, and organizational learning. The study concludes that integrating public service innovation with institutional capacity building and safety-focused performance management is essential for strengthening road safety governance. These findings highlight the strategic importance of motor vehicle testing in enhancing road safety and public value at the regional level.
