CONSERVATION, UTILIZATION OF LOCAL PLANT SPECIES, AND CULTIVATION AS THE EFFORTS OF CONTROLLING SALT AND SULFUR LEVELS AT THE BORDER OF BALURAN NATIONAL PARK, SITUBONDO REGENCY, EAST JAVA

Abstract

The diversity of plant species functions as a shelterbelt, to prevent saltwater intrusion and avoid sulfur from the crater of Mount Ijen through the Banyuputih River in Situbondo Regency. The Situbondo-Banyuwangi area is strategic (Pantura), passing through the Baluran National Park, so it is essential to maintain biodiversity and water ecosystems. Mangroves, beach vegetation, cultivated plants, and forest vegetation are indicators of environmental protection and conservation. This study aims to reveal the diversity of flora species on the border of Baluran National Park, Banyuputih sub-district, Situbondo Regency, which is allegedly contaminated with salt material from the sea and sulfur from the crater of Mount Ijen. An interview was conducted to determine the function of flora, location elevation, water pH, and well depth. The results of the biodiversity survey were then collected and diagnosed, and the scientific name was then determined. Potential species diversity at the border from an altitude of 5 m above sea level (asl) – 62 m asl included 17 families and 29 species. The data on biodiversity, location elevation, water well depth, and pH indicate low sulfur and salt content; therefore, water resources can be used sustainably by the living things surround them.
