The purpose of this case study is to identified, asses simulate and reduce delay risk in Pekanbaru – Dumai Toll Road Contruction Section 1 using stochastic method and mitigation risk. In fact, there are some article about delay analysis related to toll road contructi…
Indonesia is located on a earthquake-prone area and Riau Province is affected by the event of the earthquake epicenter on the west side of the island of Sumatra. According to the recent seismic hazard map provided by BMKG (Indonesia Meteorological Climatological and Geophysical Agency), between 2010 to 2018, the magnitude of earthquake that occurred in the west part of Sumatra Island reached mo…
This study aims to get the performance value of the irrigation network system in the Uwai Pangoan irrigation area and get budget optimization in the Uwai Pangoan irrigation area. Maintenance of irrigation networks can be realized properly if financing needs can be met optimally. The amount of the cost of maintaining irrigation networks in the past refers to the format and assessment of each ma…
ABSTRACT Pekanbaru is the capital of Riau province which has a diversity of arts. The development of art in Pekanbaru can be seen from the form of ornaments, clothing, dance, music, and the arts community. However, based on data from the Ministry of Education and Culture, it states that Pekanbaru does not have art schools at the tertiary level. Thus the Pekanbaru Art Institute is a respons…
ABSTRACT Pelita Market is one of the markets in Kubu Babussalam sub-district, precisely in Rantau Panjang Kiri village, Rokan Hilir. Judging from the location of the lamp market position, it is in a strategic position that is on the edge of the traffic road, so that access to the market does not get obstacles, because it has been equipped with adequate transportation. However, various comm…
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, …
