ABSTRACK Hoarding on soft soil has been done in several ways so that a structure can be built properly, one of which is using light material as a pile on soft soil. Stability analysis will be carried out on the embankment using foam mortar at Flyover SP.SKA. Modeling is done using the finite element method in the plaxis 16 program, this study uses Mohr – Coulomb for selected embankments,…
ABSTRACT Foamed mortar embankment is the latest technology in the embankment work. This technology uses lightweight concrete containing foam as fill material to replace conventional technology that uses soil as fill material for embankment. This research aims to find out how effective and economical foamed mortar technology is compared to conventional technology. The two types of embankmen…
ABSTRACT The construction of the Sukaramai Trade Center II parking building was planned in 2016 and managed by PT. Makmur Papan Permata is supporting the STC I building to fill the parking lot in the future, due to the additional construction of STC III so that the construction of the STC II parking building must be carried out, by increasing consumer demand and land that does not meet. T…
ABSTRACT UWC is one type of high-performance concrete for the work of fresh concrete casting, where conditions in the field have a groundwater level that can’t be avoided. Underwater concrete casting does not allow the compaction process to be carried out so that concrete with certain liquid properties is needed, fresh concrete that can flow, does not mix with water, and can solidify its…
This research discusses abrasion and sedimentation in Selat Baru Beach, Bengkalis Regency, Riau Province. The purpose of this study was to determine the condition of current patterns, surface elevation patterns and sediment transport patterns in Selat Baru Beach by making numerical models using MIKE 21 software. Data processing in this study uses data, namely bathymetry data with BATNAS data, a…
Peat water is found in many lowland areas in Sumatra, especially in Bengkalis Regency. Peat water is dark brown-black in color, has high organic content and has high acidity. Generally in remote areas on the island of Bengkalis. Peat water is also used as water for treating concrete, even though the characteristics of peat water do not meet the requirements as clean water. In this research, a s…
This study discusses the resistance of concrete using OPC and PCC cement with a concrete quality plan of f'cr 15 MPa, f'cr 20 MPa and f'cr 28 MPa through a treatment process using normal water for 28 days which is then immersed in a peat water environment with pH ranged from 3.00 to 3.80 with an average pH of 3.44 for 120 days in Bengkalis Regency. The aim of this research is to examine the com…
In the field conditions are often found a foundation design to be change due to differences in static and dynamic bearing capacity. In this research a study was conducted on the correlation between theoretical bearing capacity analysis with calendering and PDA as a dynamic test. Static bearing capacity is calculated based on N-SPT data with the Mayerhof method and the Luciano Decourt method. Wh…
Concrete material-based development is currently very important in infrastructure development. One of the developments that often occurs on peatlands, because Indonesia is a country that has the largest peatlands after Brazil. Peat is a material known for its acid content, which has a negative effect on the concrete used as a building structure. Along with this, research development is needed, …
Pile foundations are categorized including the type of deep foundations used to support buildings that hold uplift forces, especially in high-rise buildings that are affected by windmills. Along with advances in science and technology, modifications to the form and calculation of the bearing capacity of the pile foundation continues to grow. Many types or forms of modified pile foundations have…
Some watershed management activities carried out in upstream areas such as land management activities that encourage erosion, in turn will have an impact in downstream areas. The Tapung Kiri Sub-watershed is a sub-watershed of the Siak watershed located in the upstream part of which is a buffer zone for the central and downstream areas of the Siak watershed. This study aims to establish sc…
The evaluation stage of the old pavement is very important for road rehabilitation decision making. Empirical methods such as AASHTO 93 have become a long-term reference used in Indonesia. necessary to compare the suitability of the empirical design with the mechanistic-empirical which can predict the damage model based on the analysis of the loading of the wheels and the quality of the materia…
General phenomenon of the decision making of water resource development is complex, multi-sector and multi-actors, requiring an alignment between technical and non-technical aspects, systematic analysis procedure is required to integrate a variety of competitive intentions and decision Support System (DSS) is an important part as an analysis tool for decision making. The main objective of this …
ABSTRACT Research The final project which as in the title is the utilization of Geolical Carbon used is Graphane. Graphane is the basic sheets of related carbon atoms. The research process starts from the test of fine aggregate material and coarse aggregate, for fine aggregate, it is tested for the modulus of thirst, specific gravity, organic content, sludge content, volume weight and mois…
Drainage is a system created to deal with the problem of excess water both excess water that is above the soil surface. In the rainy season there is excess water in the form of surface runoff which often causes floods so people start thinking about the need for a channel system that can drain water more controlled. The existing condition of the drainage channel that does not function optima…
In general, soils have properties that vary from place to place due to the complex formations of the soil. Soil investigation is the main key in starting a construction. The Standard Penetration Test (SPT) and Sondir are the field tests most often used to estimate soil parameters in foundation analysis and design. The SPT value shows a correlation with the Sondir value and other soil parameters…
ABSTRACT This research examines the variation of initial time in time observation based on the Hijriah calendar, which produces the most accurate tidal predictions. The study analysis uses the Admiralty method with hourly observation data for 15 days and 29 days. The data uses tidal data in Kotabaru waters and simulated with three simulations, namely, the simulation of the data itself, the…
ABSTRACT The coastal area of Bengkalis Regency, especially the one directly opposite the Malaka Strait has the characteristic of sea waves that are strong enough so that it can suffer quite severe damage such as abrasion and sedimentation. Abrasion and sedimentation on the coast is influenced by the characteristic wave conditions. The purpose of this research is to make a beach modeling t…
ABSTRACT The Seberang Gunung Irrigation Area serves an area of 581 Ha. Irrigation networks that experience physical damage and decreased function will result in a decrease in efficiency, therefore maintenance activities are needed to restore the function of the irrigation network.
