This research was conducted in Unggeh Island, Badiri Sub-district, Central Tapanuli Regency, North Sumatera Province in April 2017. The research method used is Purposive Sampling and divided into 3 stations. The result of seaweed density for Enhalus acoroides species of the station I is 35 ind/m2, station II is 42 ind/m2, and station III is 10 ind m2, with the average of 29 ind/m2. The species of Cymodocea serrulata of station I is 364 ind/m2, station II is 331 ind/m2, and station III is 219 ind/m2 with the average of 305 ind/m2. Halodule pinifolia species only is found in station III with a density of 36 ind/m2 with the average of 12 ind/m2.

Abstract

Mangrove leaves have decomposition process that gives donation of organic material is a source of food for various types of biota, other organisms in mangrove ecosystem. The objectives of this study were to count the decomposition rate of Sonneratia alba litter at each station, and count the percentage of carbon nutrient content (C), Nitrogen (N), Phosphorus (F) and C / N Ratio at each station location. The research was conducted in Sei Sakat Village, Panai Hilir Sub-district, Labuhan Batu District, North Sumatera Province conducted from March to May 2017. The research station was determined by purposive sampling method at three stations with station determination based on the availability of Sonneratia alba mangrove type in Sei Sakat Village. The results showed that the decomposition rate decreased the highest litter weight of station I (30,09 g/day) while the lowest station III (7,272 g/day). Carbon (C) content during the 90 days carbon-highest decomposition process of station III (18,80%) while the lowest station I (14,87%). Nitrogen (N), the highest station nitrogen day I and III (2,95%) while lowest station II (2,50%) and Phosphorus (P), the highest Phosphorus station III (0,29%) while lowest station I (0,20%)while the ratio of C/N during peroses decomposition of 90 days that is the highest ratio of station II (7,009%).Kata kunci : Dekomposisi, Analisis unsur hara, Daun Sonneratia alba.
