Abstract

Abstract Varity of the effect of climate change including of beach disturbance on the coastal area. Beach disturbance also happen on Sukamade beach at Maru Betiri National Park (TNMB). These areas as nesting site of sea turtle are usually visiting by Green turtle (Chelonia mydas) and others sea turtle species. This research conducted to understanding of relationship between beach area and green turtle (Chelonia mydas) conservation activity was done at October 2010. Survey used to collecting primary data, and secondary data collecting from National Park Office. The result show that beach disturbance affected to the nesting activity of green turtle (Chelonia mydas). Formula show that interaction between beach extensive and number sea turtle are nesting is y = 1.4943x + 417.13 (r:2.46%). In the other hand, beach extensive and number of nest was find out the regretion formula is y = 2.3615x -656.45 (r = 20.66%). Physic and chemistry parameter in aquatic and sea turtle nest on the range are toleranced for conservation activity of green turtle. Physic and chemistry parameter in aquatic are pH 8-8.2, salinity 29-32o/oo , Light intensity 8250-8342 lux, sand pH 6,6 -8.5, sand humidity 8-8.5 and Amonia-Amonium 0.00 – 0.5 mg/l. Disolved oxsigen measuring on 6.027 – 7.627 mg/l
