Coastal areas are transitional areas between land and marine ecosystems that are very vulnerable to natural disasters, one of which is abrasion. Coastal abrasion is the process of erosion of coastal areas caused by wave activity, ocean currents, and human activities such as infrastructure development and sand mining. Ciberi Beach (Tanjung Ciberi) located in Enggros Village, Abepura District, Jayapura City, is one of the coastal areas that experiences continuous abrasion. Its strategic location and direct facing the Pacific Ocean makes this area very vulnerable to coastal erosion. Based on the author's experience while conducting Field Work Practices at the Papua River Basin Center (BWS Papua), it is known that abrasion has caused damage to public facilities and significant coastline decline since 2019 (Cepos, 2024). Strong suspicions arose from the community based on the results of interviews conducted that the construction of the Youtefa Bridge contributed to the acceleration of abrasion. Previous research also showed that the rate of abrasion in the Yos Sudarso Bay area, including Ciberi Beach, reached 0.89 meters per year. Therefore, this study aims to analyze the level of damage to Ciberi Beach due to abrasion during the period 2014–2024, and to provide recommendations for handling to reduce the impact of damage in the coastal area.

To meet the needs of safety and comfort within the Faculty of Engineering, Cenderawasih University, the campus has provided a fairly adequate parking area. With the parking area that is already available, it is necessary to conduct an analysis of the need for parking areas within the Faculty of Engineering, in order to arrange vehicles that are neater, safer and more comfortable. The formulation of this research problem is in the form of existing parking conditions, parking characteristics, and ideal parking lot capacity. This research aims to identify problems, analyze characteristics, and determine the size of Parking Lot Units. The benefits of research for reference materials, input to local governments related to parking solutions. Make a calculation of the parking lot capacity. The limitations of the research problem, which was carried out in the parking lot of the Faculty of Engineering, Cenderawasih University and the number of parking lot capacity, Calculating the capacity of the type of motorcycle and car vehicles, the survey was carried out on 3 (three) active working days, namely Monday. Wednesday, and Friday for 3 (three) weeks. This research method uses a quantitative approach with a survey type of research. With this research, it is hoped that the Faculty of Engineering, Cenderawasih University can provide adequate parking lots.
