Lightweight brick is an alternative building material for walls that has a lower density than red brick and concrete brick in general, so that it can minimize the load received by the structure and reduce the dimensions of the structure. Lightweight bricks have weaknesses in terms of compressive strength. Lightweight bricks can be made by adding additional materials to improve the quality so th…
Dompas Village is one of the areas with a high level of vulnerability to peatland fires in Bengkalis Regency. Frequent fires result in haze and disrupt community activities. In addition to the factor of minimal rainfall, fires occur due to a prolonged dry season so that the ground water level is at a depth lower than 40 cm. Therefore it is necessary to analyze the peatland fires by predicting t…

The Project Performance of Sumatera 500 kV Transmission is located Riau with a path length of ±160 kms and a total of 379 tower foundation points but in its implementation the project experienced a time delay. The absence of similar research especially in the d…
The study aims to optimize the thickness of the shear wall on the building. The object of research is Type CW.2 shear wall on the government building of Riau Province Gedung 9 (Sembilan) Lantai Kantor Dinas Provinsi Riau. Before performing optimization, the shear wall is analyzed to determine the field stresses that occur. The analysis that used to explain is plane stress analysis with fin…
This study aims to analyze and to examine the impact of land use change to the Dumai River Basin flood discharge. This research used hydrological analysis from the processing of rainfall data for the period 1980-2017 (38 years). By using Log Pearson type III distribution analysis, which was continued by using the Mononobe formula to get the flood discharge plan value. Furthermore, using data fr…
Siak River is one of the national strategic river located in Riau Province which has a very important function in the economic development of the locally, regionally and nationally. At present, Siak river has become an issue as a river that was polluted. The main objective of this research was to establish the reduction of Siak river contamination load on BOD, COD and TSS parameters about maxim…
Generally, the problems which occurred on constructions on peat soils are related to shear problems. The mechanism of equilibrium failure can occur on the soils with low bearing capacity, due to the weight of soil itself. This research was about wooden bearing capacity on peat and soft soils. In this research, the single wooden model and group model were embedded into three kinds of different…
Satellite-based rainfall data GSMap_NRT is expected to predict and forecast flooding in the area of sub watershed Pasir Pengarayan. Advances in remote sensing technology make it possible to overcome the problem of available data limitations by utilizing data sourced from satellite. The availability of many remote sensing programs connected directly to satellites speeds up the process of collect…
The main purpose of this research is to approach using Wavelet Transformation-ANFIS to find out the important parameters of the accuracy of the stream flow forecasting result, to test the accuracy of the forecasting result of the stream flow and to set the configuration of the stream flow forecasting model in Siak Watershed. The input data of this model is the discharge data from the AWLR Panta…
Menara Lancang Kuning building is one of the high-rise buildings in Pekanbaru that has considerable vulnerability to earthquakes. This building must be able to withstand earthquakes so that the risk of danger that occurs can be minimized. This study aims to determine the vulnerability of buildings to earthquakes. In this study was evaluated based on American Society of Civil Engineering 41-13 (…
This study aims to analyze and examine the correlation between peak ground acceleration (PGA) values dueto displacement, acceleration and story shear against using the dynamic spectrum response method, which is a review of high-rise buildings against the soft soil in districts / cities in Riau Province,because the soft soil is the lowest soil conditions in holding the loads. The parameters are …
Forest and peatland fires cause haze disasters that threaten aspects of human life at the local, national, regional and even global level. Loss of vegetation and the opening of peat swamp forests cause flooding in the rainy season, reduce carbon sequestration thereby increasing the greenhouse effect, and forests will lose their climate regulation function. The purpose of hydraulics modeling re…
Long segment preservation, combines routine maintenance works, widening, rehabilitation, and reconstruction of one continuous road segment into one single contract which is purposed to obtain steady road condition throughout the segment. This research is conducted to analyze the critical success of contractor’s performance in implementing this long segment preservation program. Contractors …
Reducing the risk of forest fires that have a negative impact, it is very important to study and improve the patterns and practices of forest resource management and communities living around the forest. The pattern and practice of forest resource management and the community around the forest must be formulated in a forest fire prevention strategy. This study aims to: (i) explore information o…
One of the most important components to prevent the occurrence of fires in Tropis peatland is groundwater level. Monitoring groundwater level directly in the field requires a high cost. Therefore is Background, this study will make Hydrological Model for Prediction of Groundwater Level in Tropis Peatland as Fire Mitigation Efforts based on rainfall data and groundwater level data. This reseac…
The availability of wood with suitable properties for bridge construction has become increasingly scarce. The reason is the decreasing size of the forest as a source of timber. To anticipate this, innovation is needed by utilizing wood which is still widely available but does not meet the requirements. In this regard, the purpose of this study is to examine the behavior of merau wood and wood c…
