LAJU DEKOMPOSISI SERASAH DAUN RHIZHOPORA APICULATA PADA BERBAGAI TINGKAT SALINITAS DI KAMPUNG NYPA DESA SEI NAGALAWAN KECAMATAN PERBAUNGAN
ABSTRACT: Mangrove litter has
been decomposed contributes organic matter as food source for many organism and
also to give fertility in the mangrove ecosystem. The purpose of this research
were to measure the decompotion rate and to know the nutrient of carbon (C),
nitrogen (N) and phosphorus (P) contained in the leaf litter of R. apiculata at
the various levels of salinity. This research was done at Kampung Nypa Desa Sei
Nagalawan Perbaungan, North Sumatera Province from August 2015 until January
2016 with used 50 grams of leaf litter. This research for decomposition rate of
R. apiculata used Olson method. Nutrient analysis of carbon was conducted using
Walkey & Black method, analysis of nitrogen and phosphorus nutrients was
conducted using the extraction of wet destruction. The results showed the
fastest weight loss and the rate of decomposition of R. apiculata leaf litter was at 0-10 ppt. The
highest of levels of carbon nutrients was in 10-20 ppt, the highest of levels
nitrogen and phosphorus nutrients was at 0-10 ppt
