Hubungan Kandungan Bahan Organik Pada Sedimen Dengan Morfometrik Daun Mangrove Rhizophora Apiculata Di Ekosistem Mangrove Bagian Barat Kota Dumai Provinsi Riau
The damage rate of mangrove forests in Indonesia is considered as the fastest
and largest in the world. The reduced density of mangroves can be influenced by
the water quality and the organic matter content around the mangrove ecosystem,
causing changes in the mangrove leaves both in the shape of the length and width.
This study was conducted in the mangrove ecosystem in the western part of
Dumai City, with the aim of determining the morphometric size of the leaves of
Rizophora apiculata and its relationship with the content of organic matter in the
sediment. The method used in this study was survey method, where observations
and sampling were performed directly in the field and some of samples were
analyzed in the laboratory. Mangrove density obtained from the research results
ranges from 1.967 – 4.700 ind./ha, organic matter content 10.88 -17.21%. The
morphometric size of the leaf length varies from 13.03 - 15.05 cm, the leaf width
varies from 4.65 - 5.42 cm, and the length of the petiole varies from 1.59 - 1.91
cm. There is no significant relationship between the mangrove leaf morphometric
with sediment organic matter in the studied area.
Keywords: R. apiculata, morphometric, organic matter, Dumai City.
