Abstract

This study on potential abrasion hazards in Banggai Laut Regency is intended to determine the abrasion points on the entire coast and provide alternative abrasion hazard mitigation solutions. The process of identifying abrasion disasters in the Banggai Laut Regency uses a manual interpretation method by considering several variables including coastal morphology, bathymetry, abrasion event history, the degree of coastal slope, coastal geology, and the position of the coast towards the coming wind direction. These six factors are given equal weight to their contribution to the identification of the potential for abrasion. The results of the interpretation of the identification of the potential for abrasion are indicative abrasion potential boundaries with high potential values (red), medium (yellow), and low (green). All coastlines in Banggai Laut Regency have high, medium or low abrasion potential. Most of the abrasions that have occurred in Banggai Laut Regency are in the morphology of the bay. Coastal morphology and the position of the coast towards the direction of wind coming from the high seas are the main variables causing the occurrence of high abrasion hazards in the Banggai Laut Regency. Alternative methods of handling abrasion can be in the form of mitigation of structural and non-structural abrasion hazards.

Abstract

The main activities in Serang Regency which are suspected to produce pollutants and air emissions include industrial business activities where the pollutants produced are in the form of Nitrogen Dioxide (NO2) gas which is not only dangerous for humans and animals, but also dangerous for plant life. Therefore this study tries to examine the spatial pattern of NO2 gas dispersion and its impact on settlements in Serang Regency. 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 NO2 parameter, it is seen that none of them exceed the standard of the PP No. 41 of 1999 concerning Air Pollution Control. The results of gas dispersion modeling show a tendency that gas concentration is relatively high in industrial zones, which indicates the contribution of gases from industrial business activities in several monsoons. The most extensive settlement affected by NO2 gas with the highest value (40-50 µg / Nm3) is in Cikande District covering an area of 396.4 Ha which occurs during the west monsoon (December-February).

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.
