Abstract

Some of the unfavorable characteristics of peat soil are low bearing capacity and high compressibility. The reinforcing material used in this research which functions the same as geogrid are bamboo materials (grids and woven). The bamboo material used aims to determine the carrying capacity and reduction of shallow foundations on peat soil before being reinforced and after being reinforced. Bamboo matting and rectangular patterned bamboo grids. Laboratory scale testing were used as the research methodology. The peat soil sampling location came from the area of Dusun III Banyu Urip, Banyuasin Regency, South Sumatra Province. The bamboo material is obtained from the Seberang Ulu area, Palembang City and sand is obtained from the sand depot in the Musi II area, Palembang City. The results of laboratory testing show that the addition of the number of reinforcement layers and the effective layer depth distance will give a greater bearing capacity ratio (BCR) value. The bearing capacity value of the shallow foundation before being reinforced on peat soil using Terzaghi's analysis is 45.232 kpa. Then, after testing the variation in the depth of the layer d = 0b; d = 0.25b; and d = 0.5b with the number of layers 1 layer, 2 layers and 3 layers obtained a variation which gives the highest bearing capacity value of layer depth variations d = 0.25b with the number of layers of 3 layers. The bearing capacity value is 94 kpa with a BCR value of 2.08 (percent increase of 107.96 %).

Abstract

The Regency of Kerinci and The City of Sungai Penuh are areas that prone to landslides. In 2021 and 2021, were 13 landslides on national road sections in both, which disrupted access to both areas. This study aims to calculate the index and determine the risk level of landslides on roads and bridges on national roads in both regions. Assessment methods and variables are taken based on the Guidelines for the Implementation of Risk Analysis for Natural Disasters Affecting Roads and Bridges. The index and risk level assessment are carried out by analyzing the risk factors for landslides, namely: hazard, exposure, vulnerability, external context, and capacity. The mapping of landslide risk based on Geographic Information Systems is based on scoring and weighting in all parameters, as well as overlays among all the constituent parameters. Based on the results of the study on ten national roads (with a total road length of 82.50 km) in the study area into two classes, namely: (a) low class (= 8.72%) on 7 roads located within the city, and (b) medium class (= 91.28%) on three roads connecting the cities.
