Abstract. Daris L, Massiseng ANA, Fachry ME, Jaya, Zaenab ST. 2022. The impact of fishermen’s conflict on the sustainability of crab (Portunus pelagicus) resources in the coastal areas of Maros District, South Sulawesi, Indonesia. Biodiversitas 23: 5278-5289. Using environmentally unfriendly fishing gear causes damage to coral reefs and seagrass, which are the habitat of crabs. The prohibition on using ecologically unfriendly fishing gear, such as mini trawl, in catching crabs and shrimps in the coastal area of ??Maros District, South Sulawesi, Indonesia, has triggered horizontal conflicts between traditional fishermen from 1985 until now. This study aims to identify the types of fishing conflicts and analyze the distribution of conflict areas and the maximum fishing rate that could threaten the sustainability of crab (Portunus pelagicus) resources. This research was conducted from February to July 2022 in the coastal area of ??Maros, South Sulawesi Province, Indonesia. The type of data is primary and secondary data. The data collection methods used in this study were observation, interviews, and Participatory Rural Appraisal (PRA). The analysis data used qualitative by reducing and presenting data obtained from observations, interviews, and PRA, as well as spatial analysis and Geographic Information Systems (GIS) to describe the distribution map of fishermen's conflicts. The results showed that the types of conflicts between fishermen using crab resources were agrarian conflicts, technological conflicts, and perception conflicts between fishermen using trammel nets and traps and fishermen using mini trawls. Conflicts between fishermen in resource utilization crabs occur between ??2.71-3.26 km from the coast during dark moons and 2.17-3.26 km during bright moons. Fishing conflicts have an impact on decreasing crab catches from 2015 until 2021, where the fishing effort (trip) has exceeded the sustainable fishing effort (MSY) by 690 trips/year with a total catch of 1232.3 tons/year.

Teknologi Elektrolisis untuk Mempercepat Pembentukan Batu Kapur dalam Pertumbuhan Terumbu Karang

“…Jika kerusakan terumbu karang terus berlanjut, maka akan berdampak pada hilangnya banyak spesies laut, kerugian ekonomi yang besar, dan bahkan mengancam keberlangsungan hidup manusia di masa depan [8]. Kerusakan terumbu karang menyebabkan terjadinya degrasdasi bagi ekosistem laut yang mempengaruhi fungsi ekologi dan manfaatkan ekonomi dari ekosistem laut [9]- [12] seperti rusaknya habitat kepiting [13]. Terumbu karang sangat terancam disebabkan oleh empat faktor utama yatu penangkapan ikan yang berlebihan, polusi dari daratan, kerusakan struktural akibat ulah manusia, dan pemutihan karang [14].…”

Consumer perceptions of stingrays in coastal areas of Indonesia

“…Consumers assume a significant part in reducing food impacts to more reasonable levels through dietary changes (Lucas et al 2021); moreover, the future direction for the fisheries sector is still uncertain (Chan et al 2019). The exploitation of fish resources in Indonesia is currently experiencing severe harm because of the weight of business abuse to seek momentary benefits (Daris et al 2022).…”

Characteristics of plastic waste and perceptions of coastal communities in the MLC Baluno mangrove ecotourism area, West Sulawesi, Indonesia

“…Arabi and Nahman's (2020) research show that plastic waste from coastal tourism activities negatively impacts marine habitats, biodiversity, and commercial fishery stocks and affects the community's economy. Plastic waste can come from visitor waste, marine debris, and fishing communities (Daris et al 2022;Khuu et al 2020;Nelms et al 2020). Videla and Araujo (2021) have described on the coast of Brazil that plastic waste can affect the community's economy and other social problems.…”
