Illegal fishing practices, unreported and unregulated fishing (IUU fishing) have a negative impact on the economy, ecology, state sovereignty and social problems for Indonesia. According to FAO data, the economic loss suffered by Indonesia due to IUU fishing is around Rp. 30 trillion per year. This study aims to find forms of fishery resource protection that have been carried out by the central and local governments, and to find forms of law enforcement to eradicate IUU fishing that have been carried out by law enforcement officials. This research is a socio-juridical research, using a statutory approach and a conceptual approach, the data used are primary data and secondary data, all data collected were analyzed qualitatively. The results showed that the concept of protecting fishery resources from the ideal IUU fishing practice in Indonesia is to empower coastal communities by considering ecological, socio-economic and socio-cultural aspects, while community welfare is carried out by reducing imbalances in the management of fishing fleets, availability of fishing port infrastructure, chain fishery food management, research development and utilization, fishing community participation, and central and regional arrangements.
