Abstract

Bunut River flows across Rawang Panca Arga District with its upstream in Setia Janji District, Asahan Regency and empties into balai River, Sei Balai District, Batubara Regency. The water discharge on the Bunut River causes flooding when the water discharge increases. Most flooding problems are caused by unstable and critical embankments. The aim of this research is to design a Geographic Information System and contain data regarding critical embankments in Rawang Panca Arga District. The location of critical embankments on the Bunut River can be mapped with a moteode using the ArcGis application version 10.3. Critical embankment problems on the Bunut River can be prevented with proper handling by strengthening the river banks with pairs of gabions. By strengthening river banks, it produces embankments that are safe from flood disasters when water discharge increases

Abstract

Silau River is a river that flows for 13.3 kilometers across Kisaran City, Asahan Regency. The rapid development of Kisaran City as the district capital has caused many land conversions around the Silau River Watershed. The large number of land conversions causes environmental damage to rivers. This research aims to determine the development of width, depth and scour that occurs around the river basin. Applying contour maps to river basins will reveal the area of ​​buildings and plantations that are being converted into land use. Contour maps can be built in the ArcGis application version 10.3. With the ArcGis 10.3 application, you will get the area that is being converted into land. The treatment carried out is controlling and normalizing areas that have changed function and replanting protected plants around river banks

Abstract

Porous concrete is concrete that has cavities in its structure so that water can drain. The aim of this research is to obtain compressive strength and porosity referring to the Aci 522R-10 method using a cylindrical mold measuring 15 cm x 30 cm with a soaking age of 28 days. The highest compressive strength values ​​were obtained in porous concrete specimens mixed with 10% brown shell with an average compressive strength value of 11.7 Mpa and porous concrete mixed with 5% zeolite with an average compressive strength of 11,6 Mpa. The lowest compressive strength of porous concrete mixed with 5% zeolite + 10% brown skin with an average compressive strength of 5.5 Mpa and concrete mixed with 10% zeolite + 5% brown skin with an average compressive strength of 5,9 Mpa. The highest porosity was obtained in the 10% zeolite mixture variation test object and the 5% zeolite mixture + 5% brown leather variation test object, namely 27,6%.
