| Summary: | Green turtle is a marine reptile that lays its eggs in a specific shore based on their preference, one those locations being Sindangkerta Wildlife Sanctuary, West Java. As a hatching area, Sindangkerta Wildlife Sanctuary is closely located to main roads and human settlements. This condition tends to increase artificial light illumination and anthropogenic noise towards the hatching area. The tolerance range of green sea turtles towards illumination is 0-3 lux and tolerance towards sound pressure is 39 decibels. This research aims to perceive the light illumination condition and anthropogenic noise levels on the six hatching blocks of green sea turtles in Sindangkerta Wildlife Sanctuary.
Light illumination is determined by measuring the intensity of light source facing the hatching areas. Noise levels are determined through noise pressure measurement along the coastal border at seven times intervals in a day. Results show that the highest light illumination reaches the hatching areas is 1,58 lux being a white light from the main road lighting. The highest level of noise that reaches the hatching area is 65,35 decibels with an attenuation of -5,56 decibels. Based on the values of light illumination, all the hatching blocks can be categorized as proper to the tolerance range of green sea turtles, whereas based on noise pressure, only one block can be categorized as not noisy with a noise pressure of 36,86 decibels and a attenuation of 9,78 decibels through the coastal border vegetations with thickness reaching up to 121 meters. |
