Abstract

Abstrak: Indonesia adalah negara dengan biodiversity melimpah yang memiliki berbagai macam ekosistem, keanekaragaman hayati dan beragam habitat alami yang unik dan khas. Salah satu ekosistem sebagai penyangga kehidupan masyarakat di daerah pesisir dan pantai yang dimiliki adalah ekosistem mangrove. Ekosistem ini memiliki berbagai fungsi dan peran ekonomi dan ekologi. Mangrove menggambarkan suatu kekayaan keanekaragaman hayati yang sangat penting bagi pembangunan di Indonesia.  Adapun tujuan penelitian ini adalah melakukan valuasi manfaat  tidak langsung mangrove di Kecamatan Jerowaru, Kabupaten Lombok Timur. Pendekatan yang dilakukan dalam menentukan nilai ekonomi produk dan jasa mangrove adalah analisis finansial dan analisis ekonomi. Berdasarkan hasil analisis menunjukkan bahwa nilai manfaat tidak langsung mangrove ± 42.597.267 /ha/th yang berupa manfaat konservasi air tawar, menghalangi intrusi air laut ke darat, mencegah abrasi/erosi pantai dan perlindungan dari topan dan badai, mencegah pencemaran air tambak, penyedia hara/pakan alami bagi tambak, perluasan  lahan ke arah laut, perlindungan laut dan teluk dari pendangkalan, penyimpan karbon, regulasi mikroiklim dan makroiklim, serta keanekaragaman hayati dan spesies langka

 


Abstract:  Indonesia is a country with abundant biodiversity that has various kinds of ecosystems, biodiversity, and a variety of unique and unique natural habitats. One of the ecosystems that support people's lives in coastal and coastal areas that are owned in the mangrove ecosystem. This ecosystem has various economic and ecological functions and roles. Mangroves represent a wealth of biodiversity which is very important for development in Indonesia. The purpose of this study was to evaluate the indirect benefits of mangroves in Jerowaru District, East Lombok Regency. The approach taken in determining the economic value of mangrove products and services is financial analysis and economic analysis. Based on the results of the analysis, it shows that the indirect benefit value of mangroves is ± 42.597,267 /ha/year in the form of freshwater conservation benefits, preventing seawater intrusion into the land, preventing coastal abrasion/erosion, and protection from typhoons and storms, preventing pond water pollution, providing natural nutrients/feed for ponds, expansion of land towards the sea, protection of seas and bays from siltation, carbon storage, microclimate, and macroclimate regulation, as well as biodiversity and endangered species.
