Abstract
Observations of the condition of coral reefs have been carried out in Spermonde waters from 2015 to 2018. The method used in this observation uses Underwater Photo Transect (UPT), and the data obtained is analyzed using CPCe (Coral Point Count with Excel Extensions) software. The results show that the percentage of coral cover has increased from year to year. The percentage of live coral cover in 2015 was 19.64%, 23.60 in 2016, 23.72% in 2017, and 27.83% in 2018. The increase in live coral cover from year to year is thought to occur due to the availability of nutrients. or increasing public awareness, considering this location is one of the most famous tourist attractions in Makassar. Coral reef health index values can be used to classify coral reef health. Through the analysis of the coral reef health index, an index value of 4 was obtained, which means that the condition of the coral reefs is in the “moderate” category.
Highlights
Indonesia's coral reefs have the highest diversity globally, which makes Indonesia's coral reefs a prime target for research, protection, and management (Mora et al, 2003)
This study aims to determine the distribution and cover of hard corals in Spermonde Waters to conduct sustainable management of coral reef ecosystems
Underwater Photo Transect (UPT) is a method of collecting live coral cover data using a frame measuring 58 cm x 44 cm, which is mounted on a 50 m long transect line by shooting which will be analyzed through the CPCE application
Summary
Indonesia's coral reefs have the highest diversity globally, which makes Indonesia's coral reefs a prime target for research, protection, and management (Mora et al, 2003). Sulawesi Island and its surroundings have the highest coral reefs in Indonesia and are known as the global center of coral reefs with the highest diversity (Suharsono et al, 2011). Borderless coral reefs border Sulawesi's coastline, while further offshore is the deep sea with very clear water originating from Arlindo. This results in very dense coral reef growth (Suharsono et al, 2011). Anthropogenic activities like trade and tourism are massive, coupled with port development and reclamation activities. Spermonde waters are a famous tourist site that functions as a research site for coral reefs (Hoeksema, 1988). Spermonde waters show heterogeneous habitats and are very rich in coral species (Hoeksema, 2007). Spermonde waters are experiencing rapid development of water tourism,
