The purpose of this research is to analyze environmental factors that affect the condition of rehabilitated mangroves on Harapan Island. The method used is a field survey to obtain data on mangrove conditions, environmental factor data in the form of temperature, salinity, pH, DO, nitrate, phosphate, and substrate types from mangrove ecosystems. To determine the relationship between mangrove conditions and environmental factors, a Principal Component Analysis was conducted. There are 3 observation stations in the study that are determined using the purposive sampling method with the main consideration being differences in environmental conditions. The results of the study show that the rehabilitated mangroves on Harapan Island are in good condition and very dense. However, the planting distance that is too close and the lack of thinning when the mangroves begin to grow large causes insufficient space for mangroves to grow properly. The condition of mangroves on Harapan Island, which is in the form of density and growth, is mainly influenced by the substrate in the mangrove ecosystem which is rough and the nutrient content with a fairly high concentration, where the phosphate concentration ranges from 0.038 – 0.062 mg/L and the nitrate concentration ranges from 0.059 – 0.461 mg/L. In addition, other environmental factors such as pH values that are below the predetermined quality standards and the condition of the waters of Harapan Island which are included in the lightly polluted category also affects the condition of mangroves. }, issn = {2550-0015}, pages = {190--204} doi = {10.14710/buloma.v14i2.65378}, url = {https://ejournal.undip.ac.id/index.php/buloma/article/view/65378} }
