Characteristics of Olive Ridley Sea Turtle (Lepidochelys Olivacea) Nesting Habitat along the Coast of Jembrana Regency, Bali

Abstract

This study aims to identify the characteristics of the spawning habitat of the loggerhead turtle (Lepidochelys olivacea) and the ecological obstacles that affect the spawning process in the turtle conservation area on the coast of Jembrana Regency, Bali. The research was carried out through field observation by collecting data on environmental parameters including the type of coastal vegetation, the slope of the beach, and the characteristics of sediment at the spawning location of loggerhead turtles. The results of observations show that loggerhead turtles tend to choose open sand areas with sparse coastal vegetation, sloping beach slopes, and fine-textured black sand sediments. The study also found that some turtle spawning processes are hampered by changes in coastal conditions, especially due to abrasion and the presence of artificial structures such as breakwaters that block turtles' access to the sampling zone. These findings indicate the importance of maintaining the physical condition of natural spawning habitats to support the reproductive sustainability of loggerhead turtles. The results of this study are expected to be a reference in conservation efforts and sustainable management of turtle spawning habitats, especially in coastal areas that are under pressure due to human activities and environmental changes.
