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. Currently, green construction have been implemented in building projects such as half slab. Half slab method is divided …
Peatlands in Kampar Regency are located in one of the villages, namely Rimbo Panjang Village, Tambang District, which are used for agricultural areas, plantations, housing locations and highways. In addition to the many benefits of peatland areas utilized by the community, it is possible that peatlands also have weaknesses that will have a negative impact on the surrounding community, namely pe…
ABSTRACT This study aims to evaluate the effectiveness of the School Safety Zone (ZoSS) in improving pedestrian safety at SDN 17 & 182 Pekanbaru and SDN 011 Desa Baru, Kampar Regency. The evaluation was carried out by analyzing vehicle speed, student escorts’ behavior, and pedestrian behavior. The methods used include field surveys, ZoSS facility inventory, and statistical analysis using the…
ABSTRACT Infill walls in reinforced concrete (RC) frame structures are generally classified as non-structural elements and therefore are often disregarded in structural design. However, their presence significantly contributes to the overall strength and stiffness of the structure. This study aims to compare the seismic performance of RC frame structures with and without infill walls in ac…
ABSTRACT Masonry walls in buildings are generally classified as non-structural elements and are therefore not accounted for in the structural design. In buildings with soft-story characteristics, neglecting the effect of masonry infill walls needs to be studied further, since soft-story behavior can increase the vulnerability of the structure during an earthquake. A soft story occurs when …
ABSTRACT This study analyzes meteorological drought on peatlands in Bengkalis Island using the Standardized Precipitation Index (SPI). Rainfall data from the Global Precipitation Measurement (GPM) satellite for the 2015–2024 period were processed through two approaches: manual calculation based on the Gamma distribution using Microsoft Excel and automated computation with Google Earth E…
ABSTRACT Hydrological analysis requires input from various data to be able to perform a good analysis. One of the most important data to be used in hydrological analysis is rainfall data. Rainfall is an important parameter to estimate the water available for plants and also to determine the hydrological quantities to be used. Rainfall data in a watershed can be used in various fields. In this …
ABSTRACT Prof. M.Yamin, S.H. Bangkinang Road is a national road that connects Riau province and West Sumatra province.
