Here, the Meteostunami from Krakatoa eruption and Kenanga tropical cyclone minor effect are triggered a tidal wave 3 to 15 meter over Sunda Strait, Indonesia. The early warning sensors tsunami has been worked perfectly in this area. However, a minor component from this sensor cannot asses Meteotsunami due to lack of the meteorological data. Thus, in this study aimed to analyze meteorological parameter during Meteotsunami in one-month observation (1 Dec to 31 Dec 2018) using Fuzzy Logic algorithm. The result shows in 128 combination predictor and target parameter are assessed using correlation analysis to obtain R-sq value. Here, we obtain the best cluster mode e.g. Tidal Elevation (TE) and Wind Speed (WS) as a predictor with Vulcanic Eruption Residual Water Level (RW\mathrm L mathrm v \mathrme) and Storm Surge Residual Water Level (RW\mathrmL_\mathrms\mathrms) as a target parameter reached 0.79 of R-sq value. Based on correlation analysis, we successful to obtain the fit Meteotsunami model from meteorological parameters. Here, we obtain the three Membership function’s category ($\mu$) using Gaussian Function over predictor and target parameter, respectively. Finally, the fit meteorological parameters can be estimate Meteotsunami model especially over Sunda Straait, Indonesia in near future.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Correlation analysis,Fuzzy logic algorithms,Gaussian functions,Meteorological data,Meteorological parameters,Minor components,Tidal elevations,Tropical cyclone[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Fuzzy Logic Algorithm,Krakatoa eruption,Meteotsunami,Sunda Strait[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICOIACT50329.2020.9332144[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
