This study aims to identify soil parameters that influence undrained shear strength (Cu), analyze the relationships between parameters, and compare the performance of ANN, ANFIS, …
In the 2024 Fiscal Year, the Public Works and Spatial Planning Office of Kampar Regency planned 40 road pavement construction projects under the Highways Division. However, due to budget limitations, only 14 projects could be realized in the Budget Implementation Document (DPA), with an available budget of IDR 3.12 billion out of the total required budget of IDR 55.33 billion, or approximately …
The coastal peatland area of Bengkalis Island experiences drought, fires, coastal erosion, and bogburst phenomena. Direct groundwater level (TMAT) monitoring using monitoring wells is expensive, necessitating alternative hydrological model predictions utilizing satellite rainfall data. This study developed an empirical model for predicting daily TMAT fluctuations in coastal peatland in Bengkali…
In the experimental shaking table test, dynamic loads were simulated using a shaking table system equipped with a driving motor with adjustable frequency, allowing lateral motion of the table. This study aims to analyze the structural response of a scaled model of the terminal building of Sultan Syarif Kasim II Airport, Pekanbaru, with a scale ratio of 1:120 when subjected to dynamic loadin…
This study aims to analyse the lateral displacement of steel portals at specific points of a building due to seismic loads through experimental and numerical approaches. The experimental approach was conducted using small-scale shake table testing to simulate the dynamic response of the structure to seismic loads, while the numerical approach was conducted using the finite element method to mod…
Indonesia, as a tropical country, exhibits high rainfall variability, making precipitation a critical parameter across various sectors such as agriculture, infrastructure, tourism, and public health. Rainfall is typically measured through ground-based observation stations, which generate point data; however, the number of such stations is limited due to high installation and operational costs, …
This study aims to identify the condition of road pavement and analyze the relationship of road pavement conditions to vehicle speed, vehicle operational costs and travel costs. This research was carried out on the Riau provincial road, namely the Dompas – Sepotong road section (Siak Regency Limit) with a road length of 15.75 Km. of the length of the road is divided into 75 segments, where ea…
ABSTRACT The Pekanbaru–Rengat Toll Underpass Bridge at STA 184+650 was initially designed with a wall pier; however, a two-column pier system was constructed during implementation. This change in pier configuration may affect the section capacity, lateral stiffness, and nonlinear response of the bridge substructure. This study compared the two pier systems through two separate evaluations. T…
ABSTRACT The intersection of Paus Street – Tuanku Tambusai Street in Pekanbaru City is a signalized three-way intersection that has only been operational since January 2026, but there has not been any performance evaluation since the intersection was inaugurated. This study aims to evaluate the performance of the intersection and optimize the traffic light cycle time to improve the level of …
ABSTRACT The drainage channel along Bangau Sakti Street, Pekanbaru City, from STA 2+300 to STA 2+632 has varying channel depths of 0.80 m and 1.50 m, resulting in irregular changes in the channel bed elevation. This condition has the potential to cause flow obstruction, backwater effects, and reduced freeboard. This study aims to analyze the effect of variations in channel depth on freeboard f…
ABSTRACT The Pelalawan Border–Sikijang Mati Road Section is part of the Eastern Sumatra Highway and functions as a primary arterial road with a high traffic volume.
