ABSTRACT Leaf litter decomposition which accompanied with releasing nutrient have an important function in mangrove waters. Nutrients needed for the environment from the results of decomposition, t hose are N (Nitrogen) and P (Phospor). Maron Mangrove Edupark is one of the mangrove ecosystems located in Tugurejo, Semarang City. This area has a pond and close to the beach so it serve an abrasion deterrent. To determine the role of mangrove vegetation for the environment, a study was conducted to determine the content of N and P resulting from decomposition of mangrove leaf litter in sediments. The study had been carried at from March 25, 2019 to April 22, 2019. The purpose of this study is to determine the density of existing mangrove species, determine the content of N and P in the decomposition of mangrove leaf litter in sediments and their relationship with sediment types at Maron Mangrove Edupark, Semarang. The method is an experimental method through control, manipulation of treatment in the field and observation. Station determination is based on substrate type, and there are 4 stations. The results of this study are the mangrove densities ranging from 2.72 Ind / m2 to 4.20 Ind / m2.

The total nitrogen content ranges from 0.004-0.074% and phosphate ranges from 0.164 to 1.52%. Sediment texture in station A is a sandy loam, station B is a sandy clay loam, station C and D is a clay. There is a high correlation between the texture of sediment and total nitrogen, and a moderate correlation with phosphate. }, issn = {2721-6233}, pages = {226--233} doi = {10.14710/marj.v8i3.24260}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/24260} }
