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…
ABSTRACT Indonesia as a tropical country has a high risk of hydrometeorological disasters, one of which is drought that often occurs in various regions. This study aims to analyze the level of drought and its relationship with the distribution of hot spots in Pelalawan Regency using Sentinel-2 satellite imagery through the Google Earth Engine (GEE) platform with the Normalized Difference D…
ABSTRACT Almost every year during the dry season, forest fires in peatlands occur, with the main factor being drought. In peatlands that have undergone land use change, there is excessive construction of drainage canal networks that accelerate the flow of water out of the peat. Depth to Groundwater Table is a key parameter in overcoming these problems. The ai…
ABSTRACT Drought is a condition in which rainfall falls below normal for a certain period and becomes a major threat to the sustainability of peatlands, as it can increase the risk of forest fires. This study analyzes the drought index in the peatlands of Siak Regency using the Standardized Precipitation Index (SPI) method based on CHIRPS satellite data on the Google Earth Engine (GEE) pla…
ABSTRACT As cities develop, problems related to urban drainage systems become increasingly complex. This is also the case in Pekanbaru, particularly on Jalan Arifin Ahmad, which plays a strategic role in supporting community mobility. Suboptimal drainage conditions, high levels of development, and land use changes cause flooding during the rainy season. These floods…
ABSTRACT Frequent droughts often cause various hydrometeorological disasters that commonly occur in tropical regions such as Indonesia, particularly in Siak Regency, Riau Province. This study examines drought index analysis using the Normalized Difference Drought Index (NDDI) method in the administrative area of Siak Regency. In addition, this study also analyzes the correlation between the dr…
ABSTRACT Marpoyan – Batas Kuansing is part of a road network classified as an interurban road type. The level of service (LOS) is used to indicate the quality of service provided by a road under certain conditions. The LOS reflects whether a road segment has capacity issues or not. Changes in the LOS relative to the available capacity indicate whether the road can still maintain a servic…
Pekanbaru - Bangkinang Toll Road is part of the Trans Sumatra Toll Road based on Presidential Regulation Number 117 of 2015. Where based on information from the Service Provider and Service User experiencing delays in completion. The purpose of this case study is to identify and analyze the risk factors causing delays with a probabilistic approach and lean sigma method. The research method…
This study aims to analyze the condition and performance index of breakwater structures on Bengkalis Island based on the Guidelines of the Ministerial Circular Letter of the Ministry of Public Works No. 1/SE/M/2011, as well as to analyze the priority scale for handling the breakwater structures on Bengkalis Island. The research was conducted through direct field assessment. The physical co…
This study analyzes the comparison of infiltration areas in the Siak River Basin based on the Ministry of Public Works and Public Housing Regulation Number 10/PRT/M/2015 and the Ministry of Environment and Forestry Regulation Number 10 of 2022, utilizing Geographic Information Systems (GIS). The objectives are to identify the distribution and classification variations of water catchment areas a…
In embankment construction activities, the selection and use of materials are crucial aspects that must meet various technical requirements to ensure the quality and safety of the constructed embankment. One of the key parameters often used as a reference in determining the quality of soil embankment construction is the California Bearing Ratio (CBR) value. The objective of this study is to eva…
ABSTRACT Cracks can occur in mortar during the construction service life, potentially reducing the overall mechanical performance of construction components. Selfhealing mortar is a material innovation that is able to repair cracks by the material itself without requiring additional treatment. The self-healing process can be optimized by adding certain materials that function as self-heali…
ABSTRACT Fine cracks in mortar accelerate deterioration as harmful agents such as sulfuric acid can penetrate and damage the cement paste, thereby reducing the material's durability. Selfhealing mortar is one of the potential solutions to extend service life through a continuous repair mechanism, particularly in sulfuric acid environments. Several types of materials that can function as se…
Premature damage to flexible pavements in Indonesia is generally caused by overloading, poor construction quality, and suboptimal design. One critical point of damage occurs in road widening projects, particularly at the interface between old and new structures, which is vulnerable to material fatigue and deformation due to repeated deflections. This study was conducted on the BTS Kampar Regenc…
ABSTRACT Cracks in mortar are inevitable during the construction service period, thereby reducing the durability of the mortar. Self-healing methods are used to repair cracks independently, either with natural or artificial additives or from environmentally friendly waste. Additives or healing agents that can be used to aid the self-healing mechanism include eggshell ash waste and silica f…
ABSTRACT Cracks in mortar accelerate damage because they facilitate the entry of aggressive substances such as sulfuric acid, which can damage the cement paste. Damage to the cement paste reduces the strength of the mortar. Self-healing mortar is one solution because it can repair cracks independently. Self-healing can be supported by environmentally friendly additives, such as eggshell as…
ABSTRACT Mortar is an important construction material consisting of a mixture of fine aggregate, Portland cement, and water. Mortar functions as a coating for walls, brick adhesive, and others. However, the use of cement in mortar often causes cracks in these elements. Cracks occur due to variations in temperature changes, loading, and uneven shrinkage. This study uses a solution to overco…
ABSTRACT Cracks during the service period can cause a decrease in the durability of the mortar. One innovative solution for handling cracks in mortar is self healing, which is the ability of mortar to heal its cracks by utilizing certain materials such as mineral additives and pozzolan. This study aims to examine the effect of adding pineapple leaf fibers and silica fume as cement substitu…
The increase in construction of building need a more efficient of slab construction method. The conventional formwork is considered uneconomical because expensive cost of materials and labor, longer construction time, and producing significant amount waste of wooden formwork.
