ABSTRACT Generally, structural planning involves using column-base fixed supports, which assume the base soil is infinitely rigid. In fact, the soil has a certain rigidity and is capable of deformation so that it can affect a structure, commonly called soil structure interaction (SSI). But practitioners rarely consider the interaction between soil and structural systems because of its high c…
ABSTRACT Bengkalis Island is one of the large islands in Bengkalis Regency which is located in Riau Province. According to the Central Statistics Agency (CSA), Bengkalis Island is projected to experience an increase in population and rapid development every year. This increase results in a reduction in the area of water infiltration areas. The aim of this research is to analyze the condition…
ABSTRACT The coastal area of Riau Province borders the Strait of Malacca and consists of small islands, one of which is Rupat Island with an area of approximately 1.500 km. One of the water resource problems on Rupat Island is the decline in groundwater levels due to the construction of canals by the community which can trigger seawater intrusion, because when groundwater decreases the hyd…
ABSTRACT Water catchment areas are very important to preserve groundwater resources and create an equilibrium of environmental water resources, water catchment areas are affected by changes in the environment. The rapid development of technology, especially in the field of remote sensing, makes it possible to manage spatial data on the potential of water catchment areas. Tebing Tinggi Island…
ABSTRACT The Physical Development Work Project CWR-03 AKSI ADB UNRI Postgraduate building at the end of the project in September 2023 has progress amounting to 67.0759% should be planned at 95.5614% so that there is a deviation of 28.4855%, so it’s necessary to identify the risk of delay. The aim is to identify the risk of delays using the method Relative Importance Index, as well as det…
ABSTRACT The appearance of cracks in structural elements during the service life of construction led to the emergence of self-healing methods with encapsulation that can activate the self-healing performance of a structural element, especially mortar. This study aims to assess the characteristics of self healing mortar with the use of Sodium Silicate capsules against cracks that occur in sul…
ABSTRACT Construction development in the marine environment has an impact on structural resilience because seawater is corrosive and aggressive which can cause cracks in building structures. The latest effort that can be made to increase the durability and durability of building structures is by applying Self-healing Technology by using nanomaterials in the form of silica dioxide in construc…
During its service life, mortar can form cracks and there is currently construction technology to repair these cracks by using self-healing material. Capsule-based self-healing with the healing agent sodium silicate can react with portlandite (Ca(OH)2) to form Calcium Silicate Hydrate (CSH) which fills the cracks. The purpose of this study was to assess the self-healing performance of mortar us…
ABSTRACT Self-healing concrete is a technology to heal cracks and reduce the width of cracks in mortars damaged in extreme environments such as marine environments with tidal or wetting-drying cycles. Shell waste through the combustion process will produce CaO content which has the potential to be a substitute for lime in cement making. This study aims to determine the effect of variation of…
ABSTRACT Seawater has aggressive properties that can cause cracks and reduce the durability of mortar, self-healing technology can repair these cracks independently and thus reduce repair costs. Calcined shell waste has calcium oxide (CaO) compounds that have self-healing ability by filling the cracks of mortar. The purpose of this study was to examinethe effect of variations in clam shell a…
Water is one of the essential components for basic human life. Population growth that increases every year in an area causes the need for water to continue to grow. Excessive water use can affect water availability and cause water quality and quantity to decrease. This study aims to analyze the balance between the potential availability and demand for water in the Indragiri River basin (Lubuk A…
This research aims to analyze the criteria for coastal damage in the city of Dumai and to assess the state of coastal damage that prioritizes intervention. The research location is in the coastal area Marina Beach of Dumai City, Riau Province, Indonesia. This area was chosen due to its proximity to community activities. Data analysis utilized the determination of priority levels through the acc…
Sructural analysis uses Tuned Mass Damper (TMD) and viscosity damping to reduce excessive vibrations from dynamic loads which can cause failure in building structures. To reduce damage to buildings, it is necessary to select the right ratio damping system. Many structural systems use damping ratios, including TMD and damping viscosity. The addition of the damping ratio affects different buildin…
The Simandolak – Pangean Irrigation Area (D.I Sim-Pang) is an Irrigation Area located in Kuantan Singingi district, Riau Province. D.I Sim-Pang has an area of 3,034 Ha which is divided into three Irrigation Networks, namely the Simandolak I Irrigation Network (976 Ha) which is located in Tebing Tinggi Simandolak Village, Benai District. Then there is the Simandolak II Irrigation Network (1,08…
The elevation of Pekanbaru City, ranging from 5 to 50 meters (MSL), mostly lies on relatively flat terrain, making it difficult to drain surface water. Therefore, if there is significant rainfall, it has the potential to cause flooding, as happens every year, especially in areas with relatively flat terrain due to slow drainage. This results in numerous flood points in the Bina Widya Sub-Distri…
