The methodology employed is a mixed-methods approach, utilizing questionnaire surveys distributed to 78 r…
Coastal soils are dominated by marine clay and organic-rich soils with low shear strength, high compressibility, and sensitivity to moisture content and salinity, thereby increasing the risk of infrastructure failure. 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…
The condition of people living in peatland areas makes it difficult to get clean water for daily needs and they have to buy clean water to meet their needs. Economic limitations make people in peatland areas use clean water for food, drinks and washing so that they are unable to use clean water to be mixed with concrete. People living in peatland areas only have another option to use peat water…
he rapid growth of high-rise building construction in earthquake-prone regions such as Indonesia presents significant challenges in structural planning, particularly regarding increasingly complex and asymmetrical building forms. This study aims to examine the influence of structural mass configurations on the dynamic behavior of multi-story buildings located in high seismic risk zones. The mai…
