Abstract

The condition of coral reefs is influenced by natural and anthropogenic factors. Anthropogenic activities such as coal mining will eventually have an impact on the surrounding ecosystems including coral reefs. This study aims to determine the condition of coral reefs in the waters around the operating areas of coal mining companies. This study is a preliminary study as a database that provides data on the health of coral reefs in the vicinity of the operation of mining companies in East Kutai Regency. Data was collected at Bengalon Reef, Kellie’s Reef and South Marker in March 2019 using Reef Check method, focusing on three indicators namely substrate, fish, and invertebrate. The line transect used in this method is 100 m long and divided into 4 segments. Physical and chemical parameters of the waters measured are current speed, brightness, pH, salinity, and water temperature. The condition of coral reefs in the study location is in medium category. The quality of the waters is in tolerance range of life support and coral growth. Indicator fish found were Chaetodontidae, Lutjanidae, Scaridae and Serranidae. Indicator invertebrates found were Holothuria edulis, Panulirus sp. and Tridacna spp. The dominant coral reef damage was found in boat anchors and fishing nets rubbish.

Abstract

In the era of digital government transformation, the utilization of geospatial data has become pivotal for accurate, efficient, and integrated planning, monitoring, and evaluation of infrastructure development. However, the capacity of human resources—particularly within the Office of Public Works and Spatial Planning (PUTR) of Bulukumba Regency—in managing geospatial data remains limited. This constraint may hinder the optimization of location-based decision-making in public infrastructure development. In fulfillment of the university’s third pillar of higher education—community service—the Department of Urban and Regional Planning at Hasanuddin University conducted a collaborative community engagement activity under the Faculty of Engineering’s Community Service Learning Program (LBE). The initiative focused on enhancing the geospatial data management capacity of local government officials. The activity was held on September 15, 2025, at the PUTR Office of Bulukumba Regency and involved technical staff and geospatial data officers. The methodology combined theoretical instruction with hands-on simulation, including field data collection using mobile devices and point mapping, followed by spatial data processing using freely accessible Geographic Information System (GIS) software. The results indicate that participants demonstrated high engagement and successfully acquired foundational competencies in geospatial data management. Furthermore, the activity fostered strategic academic–government collaboration, opening avenues for joint research, the development of a regional geospatial information system (SIGD), and ongoing technical mentoring. Thus, this initiative not only strengthened local institutional capacity but also laid the groundwork for sustainable, data-driven infrastructure planning in Bulukumba Regency.
