The potential contribution of the lagoon ecosystem as mangrove carbon sinks in Java

The concentration of CO2 in the atmosphere continues to increase due to the increased release of CO2 in the atmosphere effect of anthropogenic activity. Mangrove ecosystems have an important role in c on tharbon sequestration and reduce the concentration of CO2 emissions in the atmosphere. Mangrovee southern coast of Java partially growth in river mouth lagoon ecosystem, thus it has the potential for more vast mangrove restoration as carbon sink. Therefore, the purpose of this study is to assess the potential mangrove as carbon sink by the lagoon ecosystem on the Java island. One of the locations selected as an assessment sample, that is the Bogowonto Lagoon in Kulonprogo district by set up 12 plots in the planted mangrove. Allometric equation are described for assess the aboveground carbon stored in the stem and calculate the diameter at breast height (DBH) in each plot. Soil sampels were taken in each plot for assess organic carbon soil content were determined using Walkley-Black method, thus the belowground carbon sink was calculated. There was total potential mangrove carbon sink in Java which is 11,758,729.65 tons of CO2 and it can reduce carbon emissions by 4.4 in Java Island.
