Abstract

Oceanographic parameters that affect coral reef growth are clarity, temperature, salinity and water currents taken at 20 stations using AAQ Rinko 1183 and FLOWATCH FL-03 current meter. The data processing using the IDW (Inverse Distance Weighted) interpolation method and the determination of the suitability area through scoring and weighting. The identification value consist of: (a) Clarity ranges from 2 - 6 meters, (b) Water turbidity ranges from 0.3 - 4.32 NTU, (c) Bottom substrate type is fine black sand, (d) Current velocity ranges from 0.1 m/s - 0.4 m/s, and (e) TSS ranges from 35.6 - 351 mg / L. The suitability of placing artificial reefs is classified at the appropriate level (S2), as a support for the survival of fishermen and local communities in Damas Beach, Trenggalek Regency.

Abstract

Pantai Putri Menjangan, has good condition of coral reef, is located at Gerokgak District, Buleleng, Bali. Natural threat came from other inventebrate such as the coral eater, Acanthaster planci, that prey on coral tissue. A. planci is from family Acanthasteridae has 7-12 arms covered by toxic spines with 25-35 cm of body diameter. The aim of this research was to know abundance of A. planci at Pantai Putri Menjangan. To observed abundance of this creatures, we performed a belt transect 10x30 m in 5 stations. All A. planci inside of transect was count, note color and their diameter. We also record types of substrates and coral lifeform in this location. The study showed the abundance of A. planci in stations 1-3 was lower about 0.0067 individu/m2 and higher in station 5 was 0.03 individu/m2. In conclusion that no outbreak sign in this location.
