Abstract

Coral reefs are one of the most productive and most diverse coastal ecosystem. This ecosystem is the habitat of marine biota such as reef fish, molluscs, crustacea, seaweed, marine plants and so on that use this place as a place to breed, look for food and protection (Romimohtarto, 1991). Coral reef ecosystems are one of the natural resources, where coastal communities benefit from these resources. This study aims to determine the shape of coral reefs (lifeform) and the percentage of coral reefs, and to estimate the economic benefits of coral reef ecosystems in the waters of Bajo-Guruapin Village, Kayoa District, South Halmahera Regency, North Maluku Province. in the waters of Bajo - Guruapin are Acropora Branching (ACB), Acropora Submassive (ACS), Acropora Tabulate (ACT), Coral Branching (CB), Coral Encrusthing (CE), Coral Massive (CM), Coral Foliose (CF), Coral Submassive (CS) and Soft Coral (SC). From the results of the analysis, the percentage of coral cover ranged from 35.65 to 74.42% consisting of hard corals and soft corals so that the condition of coral reefs in Bajo - Guruapin waters can be categorized as conditions up to good.

This study used mixed research methods between quantitative and qualitative research with the aim of complementing the description of the study results regarding the phenomenon being studied and to strengthen research analysis. Data collection consisted of interviews, questionnaires and field observations. The assessment of plant success was carried out through a sampling technique using the Systematic Sampling with Random Start method, ie the first plots were made randomly and the next plots were made systematically. The results showed that the plant height growth (Growth rate) in Tafaga Village in an area of 100 x 100 meters with an average of 31 cm. While the area is 100 x 50 meters with an average of 49 cm. Meanwhile, in Figur Village, the general population experienced good growth with an average of 63 cm. The success of rehabilitation activities in Tafaga Village was very low at 9% and 21% so that they were not successful overall. While in Figur Village it is considered successful with 80% success.

Abstract

Coral reefs are a group of coral animals that live in symbiosis with a type of algae called zooxanthellae. Coral reefs themselves have functions and benefits as well as very important meaning for human life both in terms of economy and as a support for tourism activities. This study aims to estimate the economic value of using coral reef ecosystems on Maitara Island, seen from the value of direct benefits as fishing grounds, value of coral mining, tourism value and research value and estimating the value of indirect benefits as the manufacture of breakwaters and spawning areas. (nursery ground). Based on the results of the study, the actual condition of coral reef ecosystem resources in the waters of Maitara Island, Tidore Island City with an area of 17.55 Ha, has an economic value of direct use of coral reef ecosystems during 2019 of Rp. 14,762,522,910, which consists of a fishery benefit value of Rp. 6,858,991,660, the value of coral mining is Rp. 1,485,000,000, tourism value Rp. 12.060.000 and research value Rp. 5,850,000. While the indirect benefit value of coral reefs on Maitara Island in 2019 was Rp. 6,400,621,250, which consists of making a wave barrier of Rp. 6,380,000,000 and the value of the nursery ground is Rp. 20,621,250.
