This research as conducted in order to provide information quickly related to the category of A. planci hems in the Sombori tribe. The monitoring method used is the time s imming method hich is carried out for 2x10 minutes. Categorization of outbreak determination using threshold approach developed in the ORANET (Oceania Regional Acanthaster Network) program. Monitoring the abundance of A. planci as carried out in seven locations with 10 observation points, namely Dongkalan Kecil Island with 123 individuals, Dongkalan Besar Island with 5 individuals, Mbokita Island with 60 individuals, Kayangan Island with 7 individuals, Red Sand Beach with 5 individuals, Air Kiri Beach with 6 individuals, and Goa Alo Beach with 6 individuals. The high number of A. planci individuals is only found on 2 islands, namely Dongkalan Kecil Island and Mbokita Island.
