Abstract

The Bagek Kembar Mangrove Ecosystem Essential Area (EEA) in West Lombok is a critical habitat that supports various aquatic organisms, including mollusks. This study aimed to identify and analyze the diversity of mollusks from the classes Gastropoda and Bivalvia, within the Bagek Kembar mangrove ecosystem. Sampling was conducted from February to April 2025 using the quadrat transect method, and data were analyzed using the Shannon-Wiener diversity index (H′), Pielou’s evenness index (E), and Simpson’s dominance index (C). A total of 2,368 individual mollusks were recorded, comprising 20 species: 16 Gastropods and 4 Bivalves. The family Potamididae from the class Gastropoda was the most dominant, with Cerithidea cingulata being the most abundant species. Gastropods exhibited moderate diversity (H′ = 2.20), high evenness (E = 0.79), and low dominance (C = 0.15), while Bivalves showed low diversity (H′ = 0.61), moderate evenness (E = 0.44), and moderate dominance (C = 0.70). These results indicate that mollusk diversity in the area is at a moderate level. The findings highlight the importance of mangrove ecosystems in maintaining mollusk diversity and support their use as bioindicators in environmental monitoring and local conservation strategies.

Abstract

Mangrove ecosystems provide essential ecological and socio-economic services that support coastal sustainability, yet their potential has not been fully optimized in ecotourism development. This study aims to identify the roles of mangrove ecosystem services, review effective ecotourism models, and formulate development recommendations for the Tanjung Batu Mangrove Area. A Systematic Literature Review (SLR) following the PRISMA 2020 protocol was conducted, and 52 eligible articles were analyzed using thematic synthesis supported by bibliometric mapping. The findings show that regulating and cultural ecosystem services are the most influential in shaping mangrove ecotourism, particularly through shoreline protection, habitat support, and educational value. Community-based ecotourism (CBE), educational tourism, and conservation-oriented approaches emerge as the most effective models across tropical coastal regions. Successful implementation is determined by ecological integrity, community participation, and supportive governance. For Tanjung Batu, integrating these components offers a strategic framework for enhancing tourism potential while strengthening conservation outcomes. This study recommends applying a hybrid community-based and education-focused ecotourism model supported by governance collaboration to ensure long-term ecological resilience and sustainable coastal development.
