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…
ABSTRACT PCI and PCU type girders have similarities in the economic span range, which is 25–40 meters, as stated in the Practical Guidelines for Bridge Technical Planning (2021). This study aims to compare the use of PCI and PCU girders on the Siak Bridge sta. 195+500 Trans Sumatra Toll Road Rengat-Pekanbaru section Lingkar Pekanbaru. The comparison is made based on the parameters of pre…
ABSTRACT This study aims to determine the population projection and the amount of clean water needs in Tenayan Raya District for 2025-2040, using a method in the form of data analysis. The methods used in calculating the population are arithmetic, geometric, and exponential methods to project the population, as well as standard deviation analysis to determine the most appropriate method. 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…
