## Abstract
Abstract Global warming caused by various human activities results in increased concentrations of Greenhouse Gas (GHG) emissions. This causes the problem of climate change. One of the sources of Indonesia’s greenhouse gas (GHG) emissions comes from the agricultural sector. Methane (CH4) is the second most important greenhouse gas and has a global warming potential 25 times greater than CO2. Paddy fields contribute to GHG emissions due to the condition of the rice fields which are always flooded which produce gases such as CO2, N2O and Methane (CH4). This study aims to determine the effect of microbial abundance on increasing emissions of methane gas (CH4) in paddy fields. This research was conducted by collecting samples in the field with variations at 30th, 60th, and 90th day after planting (DAP). The results of laboratory analysis showed that the results of C-Organic analysis were 1.45-2.56%, the results of soil microbial abundance analysis for the total bacterial population ranged from 1.2 x 104 - 6.3 x 105 (CFU/g) and the results of analysis flux of CH4 at 30thDAP sampling from the three sample points ranged from 2.13 - 11.29 (mg/m2/hour). For the 60thDAP sample from the three sample points it ranges from 10.01 - 22.77 (mg/m2/hour). For the 90thDAP sample from the three sample points it ranges from 21.98 - 25.54 (mg/m2/hour). The results of the analysis of methane (CH4) emissions in one growing season show different values of methane emissions at different locations and sampling times.
