ABSTRACT This study aims to develop an empirical equation to predict the California Bearing Ratio (CBR) based on the results of the TVA Penetrometer (Hand Cone Penetrometer) test on soft soils, particularly in coastal areas. Soil samples were prepared by mixing bentonite clay, kaolin, and sand, then compacted and tested in the laboratory to obtain CBR values and QcTVA readings. Stepwise re…
ABSTRACT In geotechnical engineering, professional actions and expert judgment are often essential in soil investigation methods. In coastal areas, expansive soils with sandy sedimentation lead to reduced bearing capacity and challenges in field instrumentation. This study models a clayey sand (SC) mixture using Bentonite and Kaolin as fine fractions, which exhibit expansive behavior and p…

The r…
ABSTRACT In the construction of the Trans-Sumatra Toll Road, Rengat–Pekanbaru Section, specifically at the Pekanbaru Ring Road segment Sta. 193, two identical bridges are planned to employ prestressed concrete box girder structures. The construction of these bridges adopts the balanced cantilever method. Implementation of the balanced cantilever technique requires optimization through cr…
ABSTRACT The curve at Km 50 of the Pekanbaru-Bangkinang Highway is classified as a sharp and closely spaced compound curve and is identified as an accident-prone area, marked by accident-prone zone signs on one direction of the curve. Based on traffic accident data from 2019-2024, five accidents have occurred at this location. Noncompliance of the geometric design with current standards is…

ABSTRACT Concentrically Braced Frame (CBF) is one of the commonly used seismic-resisting systems because it can effectively resist lateral forces. However, this system has a weakness, which is the risk of buckling under compressive forces that can reduce the structural capacity. Buckling Restrained Braced Frame (BRBF) is a development of CBF with restrainers that prevent buckling. This fin…
ABSTRACT Slope stability is essential in ensuring the safety of residential areas, especially in regions with unstable soil conditions. This study aims to design gravity and cantilever type retaining walls as an effort to prevent soil instability at the Derofizha Permata Indrapuri Housing site in Pekanbaru. The methods used include field surveys, collection of soil parameter data, manual c…
ABSTRACT The research aims to analyze the stability of the slope at the Derofizha Permata Indrapuri Pekanbaru Housing site to obtain the Safety Factor value, The safety factor is an important consideration in the stability of slopes or embankments. The stability of a slope is a crucial factor in work that involves excavation, earthworkers, rocks, and mineral materials. The results of this …
The design of pile foundations requires accuracy in determining the soil bearing capacity in accordance with field conditions. This research was conducted to compare the bearing capacity of single pile foundations based on two types of data: Cone Penetration Test (CPT) results and laboratory soil test data. The study was carried out in the Indrapuri Housing area, Pekanbaru City. The analysis me…
ABSTRACT A slope is a land surface that makes a certain angle to the horizontal plane, causing a slope. Slopes that have a crucial slope need to be analyzed for slope stability. The purpose of this study, is a comparative analysis of the slope safety factor between the limit equilibrium method (Limite Equilibrium Method) and the finite element method (Finite Element Method) in terms of the…
ABSTRACT Erosion can reduce the capacity of water channels. So to overcome the problem of erosion in river channels, a river bank protection structure is needed. Therefore, in this study, analyzing the capacity of the river cross-section. This study aims to determine the flow rate of the Kampar River, the depth of the Kampar River in order to determine the river discharge after the constructio…
ABSTRACT This study aims to analyze hydrometric parameters in the Air Hitam River by comparing two commonly used measurement methods: the float method and the current meter method. Both methods are employed to measure flow discharge and water velocity along the river, which exhibits variations in flow due to natural factors and human activities. The float method tracks the time taken by a floa…
ABSTRACT This research analyzes water discharge with variations in flow velocity measurements at Sail River, Bukit Raya District, Pekanbaru City. Water discharge is a crucial parameter in hydrology, playing a significant role in water resource management, flood mitigation, and infrastructure planning. The study aims to determine the water discharge value based on flow velocity measurement meth…
ABSTRACT The Tangkerang River in Pekanbaru City frequently experiences flooding due to high rainfall that exceeds the river’s capacity. This study aims to design a retention pond (embung) as an alternative flood control measure to reduce the peak discharge of the river flow.
