Abstract The Indian Ocean Dipole (IOD) phenomenon is a phenomenon that occurs in the Indian Ocean due to differences in sea surface temperature anomalies between the Western Indian Ocean and Eastern Indian Ocean regions. This interaction produces high pressure in the Eastern Indian Ocean (South of Java and West of Sumatra) which causes the flow of air masses to blow westward. The IOD phen…

Mangrove forest are able to store carbon from the air through photosynthesis by converting CO2 into biomass based on ecological function. The better ability of mangrove forest to absorb CO2 has not been widely recognized by the wider community, this is one of the reasons why people do not consider the existence of mangrove forest and not maintain their sustainability. Based on that reason, this…
