Abstract

The newest finding in 2016 about Baribis thrust, if it is pulled straight from Cibatu to Tangerang, it is roughly found that this fault passes through several sub-districts in Jakarta. Meanwhile, Center of Jakarta as the capital city, many governmental, economic, and business activities are conducted in this area. And also Geographic Information System (GIS) techniques are commonly used for monitoring and damage assessment for many natural and geological hazards. The present study, GIS techniques have been used to generate various thematic layers to assess earthquake hazard with a suitable numerical ranking scheme, mesh processing, and spatial data integration. The results also show that the proposed model provides reasonable earthquake potential index (EPI) from elevation, slope, magnitude, active fault, and epicentre parameters compared to the peak ground acceleration (PGA) in Center of Jakarta. The result of the EPI map explained just a little area in Center of Jakarta has very high EPI. Very high EPI area mostly in southeastern part in the study area, exactly in Menteng sub-district. And also illustrated, spatially in the more northward area indicate the smaller of the EPI in the study area. EPI resulted from the calculation of surface parameter have the same indication or same trend with PGA.

Abstract

In Serang Regency, pollutants and air emissions are produced by industrial activities, including Sulfur Dioxide (SO2) gas. SO2-polluted air causes problems to the human respiratory system. This study examine the spatial pattern of SO2 gas dispersion and its impact on settlements in Serang Regency using geostatistic and Inverse Distance Weighting (IDW) method in Arc GIS. Based on the results of ambient air quality measurements in Serang Regency, which have been measured by the Serang Regency Environmental Agency from 2015 - 2019 for the SO2 parameter, it can be seen that none of them exceed the standard of the PP No. 411999 concerning Air Pollution Control. The results of spatial analysis of gas dispersion show tendencies of high gas concentration in industrial zones, which indicate the contribution of gases from industrial business activities in several monsoons. The most extensive settlement affected by SO2 gas with the highest value of 40-50 µg / Nm3 is on Cikande District covering an area of 3.173,77 Ha which occurs during the west monsoon from December to February.
