ABSTRACT A construction project has specific objectives that must be met, namely on-time, onbudget, and on-quality, as well as safety in the construction process. These objectives will be met if there is good management, one of which is project time management. This study aims to evaluate the application of Project Time Management (PTM) in construction projects carried out by contractors i…
ABSTRACT The behavior of a building during an earthquake is highly dependent on several parameters such as shape, size, and overall geometry. These parameters will determine the overall capacity of the building, especially seismic parameters. The ratio of vertical aspect (H/L or H/B) and aspect ratio horizontal ratio (L max /L min) affects the efficiency and stability of the structure in w…
ABSTRACT The Rokan Kiri sub-watershed is one of the sub-watersheds of the Rokan watershed. On February 26-27, 2025, flooding occurred due to the overflowing of the Rokan Kiri River. To reduce the risk of flooding, water structures are needed whose planning requires accurate design flood discharge to produce reliable, safe, and economical water structures with hydrological analysis. One app…
ABSTRACT Pangkalan Kerinci District is an area with a high level of flood risk caused by intense rainfall, overflow of the Kampar River, and land use changes due to industrial and residential activities. Based on a survey conducted by PT Tri Karsa (2022), there were 20 flood points in Pangkalan Kerinci Kota Village and 4 flood points in Pangkalan Kerinci Barat Village. The preparation of t…
The condition of people living in peatland areas makes it difficult to get clean water for daily needs and they have to buy clean water to meet their needs. Economic limitations make people in peatland areas use clean water for food, drinks and washing so that they are unable to use clean water to be mixed with concrete. People living in peatland areas only have another option to use peat water…
ABSTRAK The growth of the vegetable oil refining industry generates a large amount of solid waste known as Spent Bleaching Earth (SBE), which can cause environmental pollution if not properly managed. This study aims to utilize extracted SBE as an additive material in brick production to reduce environmental impact while producing an eco-friendly alternative building material. The research was…
ABSTRACT Construction projects require proper control so that they can be completed according to the planned schedule and budget. This study aims to evaluate the cost and time performance of the University of Riau Postgraduate Center Building Project through the application of the Earned Value method. This method is used because it is able to show the relationship between cost, time, and t…
ABSTRACT This study aims to utilize extracted Spent Bleaching Earth (SBE) waste as an additive material in the production of clay bricks. SBE waste is a by-product of the palm oil bleaching process, which is abundantly available and has the potential to cause environmental pollution if not properly managed. The variations of SBE content used in this research were 0%, 30%, 40%, 50%, and 60% of …
he rapid growth of high-rise building construction in earthquake-prone regions such as Indonesia presents significant challenges in structural planning, particularly regarding increasingly complex and asymmetrical building forms. This study aims to examine the influence of structural mass configurations on the dynamic behavior of multi-story buildings located in high seismic risk zones. The mai…
ABSTRACT Indonesia as a tropical country has a high risk of hydrometeorological disasters, one of which is drought that often occurs in various regions. This study aims to analyze the level of drought and its relationship with the distribution of hot spots in Pelalawan Regency using Sentinel-2 satellite imagery through the Google Earth Engine (GEE) platform with the Normalized Difference D…
ABSTRACT Almost every year during the dry season, forest fires in peatlands occur, with the main factor being drought. In peatlands that have undergone land use change, there is excessive construction of drainage canal networks that accelerate the flow of water out of the peat. Depth to Groundwater Table is a key parameter in overcoming these problems. The ai…
ABSTRACT Drought is a condition in which rainfall falls below normal for a certain period and becomes a major threat to the sustainability of peatlands, as it can increase the risk of forest fires. This study analyzes the drought index in the peatlands of Siak Regency using the Standardized Precipitation Index (SPI) method based on CHIRPS satellite data on the Google Earth Engine (GEE) pla…
ABSTRACT As cities develop, problems related to urban drainage systems become increasingly complex. This is also the case in Pekanbaru, particularly on Jalan Arifin Ahmad, which plays a strategic role in supporting community mobility. Suboptimal drainage conditions, high levels of development, and land use changes cause flooding during the rainy season. These floods…
ABSTRACT Frequent droughts often cause various hydrometeorological disasters that commonly occur in tropical regions such as Indonesia, particularly in Siak Regency, Riau Province. This study examines drought index analysis using the Normalized Difference Drought Index (NDDI) method in the administrative area of Siak Regency. In addition, this study also analyzes the correlation between the dr…
ABSTRACT Marpoyan – Batas Kuansing is part of a road network classified as an interurban road type. The level of service (LOS) is used to indicate the quality of service provided by a road under certain conditions. The LOS reflects whether a road segment has capacity issues or not. Changes in the LOS relative to the available capacity indicate whether the road can still maintain a servic…
Pekanbaru - Bangkinang Toll Road is part of the Trans Sumatra Toll Road based on Presidential Regulation Number 117 of 2015. Where based on information from the Service Provider and Service User experiencing delays in completion. The purpose of this case study is to identify and analyze the risk factors causing delays with a probabilistic approach and lean sigma method. The research method…
