ABSTRACT In a pavement mixture, the filler has a significant effect because it functions as a cavity filler in the mixture. One of the fillers that can be used is Kapur Tohor. Tohor lime is the result of burning raw lime at a temperature of approximately 900 C which can be utilized and contains silica so that it can improve the quality of the pavement mixture. The purpose of this study was…
ABSTRACT Advancements in science and technology of civil engineering have led the development of modifications to the shape of pile foundation. Modification of the pile foundation by adding wings to the pile is one way to increase skin friction on soft soil, so that a greater bearing capacity is obtained. In this research, piles were modeled with variations of wing’s lengths of 0.50D, 0.…

ABSTRACT Flood routing in the Riau region is influenced by one factor, namely the water level in the river area, water level data processing using the Artificial Neural Network program with Back propagation Method. Data processing of water level carried out is to predict the water level in the downstream by using the water level data in the upstream and the water level data in the downstre…
ABSTRACT Tidal flat is formed because of sedimentation processes which are mainly influenced by the coastal hydrodynamic. Tidal flat formation on the coastal peat is a unique phenomenon that has occurred at western part of Bengkalis Island, Riau Province, Indonesia. The method used in this research was simulation of tidal flat formation with five wave variations. Simulations were carried o…
ABSTRACT Grab is a technology company from Malaysia that only provides public transportation transportation service applications, while the vehicle itself is owned by partners who have joined PT Grab Indonesia. The growth of online grab services in Pekanbaru which is so rapid and has succeeded in attracting many workers as drivers has become a phenomenon that needs attention. This study a…
ABSTRACT Clay soils with high water content are generally classified as soft soil and have poor bearing capacity. For this reason, it is necessary to improve soil conditions, one of which is the stone column method. Stone column is a method of increasing soil bearing capacity by using vertical columns made of stone or sand. The use of fly ash and bottom ash as stone column material is beli…
ABSTRACT The phenomenon of the formation of tidal flats is a unique phenomenon that is very interesting to study. The purpose of this study was to analyze the wave characteristics of the island peatlands and the tidal flat formation process. The method used in this research is bed load simulation and one-way waves with variations in wave period, wave height and wavelength. Simulations were…
ABSTRACT Soil conditions in Riau province are dominated with soft soils in the form of clay, silt and peat. Soft soils generally have low bearing capacity and high compressibility. Stone column is one of soil improvement method that can be done to fix these problems. Several previous studies have shown that the application of a layer of sand bed on top of stone columns could improve bulge …
ABSTRACT The importance of the performance of concrete construction demands an adequate quality. Many research studies have been carried out to obtain alternative discoveries, various ways have been done to produce concrete with even better quality, one of which is by using synthetic materials in concrete with the addition of Geolical Carbon which has been processed into graphane for all a…

ABSTRACT Efforts to increase the efficiency of the use of wood can be done by utilizing fastgrowing types of wood. In addition, low-quality wood can be used so that the use of wood is more efficient. In some developed countries, laminated wood is continuously developed using low quality wood species. Laminate wood is a combination of a number of wooden beams to form a unified whole. Jabon …
ABSTRACT Teropong road is a two-lane two-way undivided (2/2 TB) type of road was a local road with ± 2 km of road length and 6 m of width, that connects between Cipta Karya road and Soekarno Hatta road, currently part of teropong road is still in the form of landfill road along 1.3 km which entered the Kampar district area, and has been paved along 0,7 km that entered Pekanbaru City. Base…
ABSTRACT Changes in land use due to housing construction can indirectly damage water catchment areas. This results in reduced rainwater catchment areas which cause rainwater to collect in existing drainage channels. This condition will cause an increase in the volume of surface water that enters the drainage channel and the water overflows in the channel which can cause puddles or even flo…
