ECOSYSTEM CONDITIONS AT LENDANG LUAR BEACH, LOMBOK ISLAND, INDONESIA

Abstract

This study aims to identify biotic and abiotic components and describe the ecosystem conditions at Lendang Luar Beach, Malaka Village, Pemenang District, North Lombok Regency, West Nusa Tenggara. This study used exploration and direct observation methods. Data were collected through observation and documentation of various organisms and coastal environmental conditions, then analyzed descriptively. The results of the observations showed the presence of several organisms, including coralline algae (Amphiroa rigida), sand crabs (Ocypode sp.), seaweed (Ulva lactuca), barnacles (Cirripedia), sea urchins (Echinoidea), starfish (Asteroidea), and coastal vegetation in the form of coconut trees (Cocos nucifera L.) and sea pandan (Pandanus tectorius). In addition, mollusk shells and inorganic waste were found along the beach. The presence of these organisms indicates that the Lendang Luar Beach ecosystem has various components that support coastal ecological functions. However, the presence of inorganic waste indicates the potential for environmental disturbances due to human activities. Therefore, efforts to maintain beach cleanliness and preserve coastal habitats are needed to support the sustainability of the Lendang Luar Beach ecosystem.
