Abstract

AbstrakSerasah mangrove berperan penting dalam kesuburan perairan pesisir. Serasah mangrove yang terdekomposisi akan menghasilkan unsur hara yang diserap oleh tanaman dan digunakan oleh jasad renik di lantai hutan dan sebagian lagi akan terlarut dan terbawa air surut ke perairan sekitarnya. Penelitian dilakukan dengan cara menghitung penyusutan bobot serasah awal yang terdekomposisi kemudian membandingkan bobot serasah yang terdekomposisi tiap bulan. Penelitian bertujuan untuk mengetahui pengaruh tingkat kedalaman tanah yang dapat mempercepat proses dekomposisi serasah. Hasil penelitian menunjukkan bahwa kedalaman tanah berpengaruh terhadap laju dekomposisi serasah jenis Avecennia lanata,  tiap kedalaman tanah memiliki jenis dan jumlah mikroorganisme yang berbeda-beda, kondisi ini akan dapat berpengaruh terhadp laju dekomposisi serasah dan tingkat kedalaman 10 cm yang paling berpengaruh terhadap laju dekomposisi serasah Avecennia lanata yaitu yaitu sebesar 0,29-0,39 gram/hari. Kata kunci: dekomposisi serasah, Avecennia lanata, Tingkat kedalaman tanah AbstractMangrove litters play important role in coastal water fertility. The decomposed mangrove litters will produce nutrient absorbed by plants and some of them will be used by microorganisms in wood floor and the other will be dissolved and carried by the low tide to the surrounding waters. The research was conducted by calculating the depreciation of the initial weight of the decomposed litters and comparing it to the decomposed litter weight every month. The research aimed to find out the influence of soil depth that could accelerate litters decomposition process. The research result indicated that soil depth influenced the decomposition rate of Avecennia lanata litters. Each soil depth had different type and number of microorganisms. The condition would influence the decomposition rate of the litters. Soil depth of 10 cm was the most influential on the decomposition rate of Avecennia lanata litters, which was 0.29-0.39 gram/day. Keywords: litters decomposition, Avecennia lanata, Soil depth
