This document discusses the threats faced by sea turtles and efforts to protect their eggs. It notes that only 1 in 1000 sea turtle hatchlings survive to adulthood. It also states that 12,000 eggs were stolen in one month from a small Indonesian island. The document then introduces Penyu Ranger, a project that uses devices to monitor and protect sea turtle nests, alerting rangers to threats via an app. The app allows rangers to manage multiple devices, record nest data, and view monitoring results. The overall aim is to help conserve sea turtles facing extinction.
