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…
Mortar is an important binding matrix in construction, playing a role in protecting structures from damage and cracking. Handling seepage and corrosion in structures is a major concern. Research shows that the addition of Acrylic Binder to mortar mixes improves weathering, chemical, abrasion resistance and adhesive strength. This study aims to assess the characteristics of mechanical and physic…
The Batang Anai Irrigation Area is one of the mainstay irrigation areas in West Sumatra Province. The Batang Anai Irrigation Area provides irrigation flow on the right and left sides of the weir. In this research, the review is the left side of the weir, namely the Batang Anai Irrigation in the Sekayan Secondary Channel with an irrigated area of 225 Ha. As time goes by, the function of irrigati…
The Simandolak-Pangean Irrigation Area (DI) consists of the Simandolak 1 Irrigation Network, the Simandolak 2 Irrigation Network and the Pangean Irrigation Network with an area of 976 Ha and 1,087 Ha respectively, while the Pangean Irrigation Network has an area of 971 Ha. Analysis of the performance of the Pangean Irrigation Network needs to be carried out in order to improve the function of t…
Based on data from the Ministry of Environment and Forestry of the Republic of Indonesia in 2023, the districts experiencing the largest forest and peatland fires in West Kalimantan Province were recorded as Kubu Raya, Ketapang, and Sambas. This study investigates the impact of Weather Modification Technology (WMT) on carbon gas emissions. The research evaluates whether the implementation of WM…
