Bangsring is a tourist destination on Java Island's east coast, bordering immediately with the Bali Strait. This place is referred to as Bunder, which means Bangsring Underwater. This tourism destination grew from a marine protected area (MPA) run by the Bangsring fishing community. The floating house manned by fellow Bangsring fisherman serves as a coral fish acclimation pool before they are discharged. Typically used as a preparation pool for both white-tip and black-tip reef shark species.
Furthermore, the natural and artificial coral reef habitats in Bangsing waters are popular tourist destinations. Snorkelling and diving are the most popular activities among visitors. From the many tourism operations that focus on the coral reef environment, fellow fishermen and tourism managers here recognize the importance of ecosystem sustainability and continue to pursue it. Several actions to preserve the coral reef ecology have been carried out here. Cooperation with other parties is also practiced here. UNY conducts activities such as assessing the growth of coral reefs and coral fish communities.

UNY's biology education department studies coral reef growth and collects periodic data from coral fish communities in Bangsring waters in three types of ecosystems. Natural ecosystems, damaged ecosystems, and artificial ecosystems have all been maintained. This activity began in 2023 as part of the innovative research activity MBKM.

Monitoring of coral reefs and reef fish is also carried out in the waters of Karimunjawa. Monitoring operations are led by marine biology educators from the Department of Biology Education UNY, who collaborate with academics from Marine Science, Brawijaya University, Malang, and the National Research and Innovation Agency's oceanographic section. One of the monitoring locations is located in the coral reef habitat of Gosong Cemara. This activity began in mid-2024, coinciding with the Department of Biology Education students' annual routine field study activities.
