Abstract Flooding in Bengkulu city is an event that occurs every year. One area that is often affected by floods is the downstream area of ??the Air Bengkulu River Basin. Flooding in the Air Bengkulu Hilir watershed is caused by an increase in water discharge due to high rainfall. This study aims to create a flood inundation map. This map was created by modeling. flood inundation in the Air Bengkulu Hilir watershed area through a simulation of flood flow. Flood inundation modeling is carried out by utilizing a special mode of analysis in Geographic Information Systems (GIS) for the creation of river geometry as well as a HEC-RAS hydraulic flow simulation program. The method of making maps with several stages, namely the first rainfall analysis, calculation of drainage coefficient and land cover. Secondly, the preparation of digital elevation data (DEM) as a source of data forming river geometry, then the flow simulation uses the flood data of the flood plan in 5 and 10 years at 1789,687 m3 / second and 1830.15 m3 / second. Flood generation is displayed automatically through the RAS Mapper site in ArcGIS. Depth The results of the flood inundation map based on the flood discharge plan for 5 and 10 years are 0 - 10,534 m and 0 - 10,571 m identified areas are Surabaya, Semarang, Bentiring, Tanjung Jaya, Tanjung Agung, Suka Merindu, Rawa Makmur, and Kampung Kelawi.

Abstract

Abstract Comparative evaluation of soil properties is used to determine soil properties in the field. Comparing several methods for grade testing aims to get results that are closest to the original data. Tests using Dynamic Cone Penetration (DCP) are commonly used. However, the method commonly used in Indonesia is in accordance with the 1993 Bina Marga regulation. Meanwhile, the method for testing DCP has many different variations. For this reason, DCP testing was carried out using 12 different methods to obtain test results from each method. The test was carried out at 6 points on the Halmahera Bengkulu road. From the test results, it is found that the largest Plastic Index value is at point A1 which is 98% while the largest CBR is at point B2, which is 62% using the NCDOT method. Of the 12 methods used, no significant differences were found, which means that all of these methods can be used for PI and CBR calculations.
