Effect of Salinity On Biomass of Avicennia marina and Rhizophora mucronata That Grown At Reed Bed System Reactor With Continuous Flow

EasyChair Preprint no. 2381

Abstract

Salinity is one of the environmental factors having an important role in controlling mangrove growth. Each type of mangrove has different adaptability. This causes the structure and composition of mangrove with distinctive boundaries, ranging from zones close to land to zones close to the ocean. This research was aimed to examine the ability to grow mangrove tillers at various levels of salinity, Avicennia marina and Rhizophora mucronata types with addition bacteria Vibrio alginolyticus using reed bed system reactor continuous flow with salinity concentration 20‰ and 25‰.

The indicator of mangrove plant growth was conducted by physical observation during the exposure time. The fresh weight (FW) and dry weight (DW) were measured at day 0 and the last day of experiment. The monitoring parameters such as pH and temperature were also measured. The results showed Avicennia marina with added bacteria have the greatest growth at concentration salinity 25‰ with dry weight was 69,27 grams. Salinity 25‰ gives a greater growth result than salinity with a concentration of 20‰. This can be seen in the dry weight of Avicennia marina and Rhizophora mucronata.
