ABSTRACT The behavior of a building during an earthquake has a significant effect on the shape, size and geometry of the building. Tall buildings with a large vertical aspect ratio affect the response of the structure when resisting lateral forces. The purpose of this research is to analyze the response of the structure with the plan earthquake to the vertical aspect ratio, then it will model …
ABSTRACT Bridges are infrastructure buildings that are commonly used and very functional in everyday. One of the structural components of the bridge is a reinforced concrete beam as a load bearer that will be forwarded to the foundation. The shear capacity of reinforced concrete beam structures sometimes cannot meet the existing requirements. This can be caused by increased loads, inadequate s…
ABSTRAK In the Riau Province, there are 1,534.581 hectares of oil palm plantations (PKS), which produce 15.2 million tons of solid trash year and 28.7 million tons of liquid waste annually. Every year the area of oil palm plantations has increased. Every 1 hectare OPM produces around 1.5 tons of solid waste of empty palm fruit bunches (EFB) annually in a dry state and 2.64 tons of EFB with a m…
ABSTRACT Concrete that uses POFA (Palm Oil Fuel Ash) as a replacement of cement and a silica combination is known as POFA-blended concrete with silica as reactivity improvement material for POFA. This study aims to examine compressive strength, porosity, shrinkage, weight change, and the effect on environment using Toxicity Characteristic Leaching Procedure (TCLP) in peat water curing for 0, 7…
ABSTRACT The compressive strength of concrete is influenced by many things, including the constituent materials, mix design, workmanship, and maintenance. The purpose of this treatment is to prevent or reduce water loss/evaporation from inside the concrete which is still needed for the continuation of the hydration process so that the optimization of concrete strength can be achieved close to …
ABSTRACT Delima Street is two lanes without a median with a width of 6 m and a length of 1,700 m and connects Srikandi Street and H.R Soebrantas Street so it is classified as a collector's road, therefore many vehicles pass through this road. As a result of the large number of vehicles that pass through this road, this is one of the causes of certain damage to the road body. The purpose of thi…
ABSTRACT The intersection of Durian street - Serayu street located in Payung Sekaki District, Pekanbaru City is an unsignalized three-arm intersection and often experiences traffic jams. The purpouse of this study was to analysis the performance of the unsignalized intersection of Durian street - Serayu street. The method for calculating this unsignalized intersection is guided by the MKJI 199…
ABSTRACT Material strength becomes an important sight because it is needed in structural design planning. In general, the compressive strength of concrete is influenced by the composition of the concrete, but it turns out that it is not only influenced by the composition of the concrete, but also by the speed of loading. The effect of variations in axial loading speed on the compressive streng…
ABSTRACT The Tapung Kanan Watershed is part of the Siak Watershed which is located in the Siak River Basin, which is one of the watersheds with critical conditions and requires priority handling. This is due to the uncontrolled use of water resources, causing the availability of water to tend to decrease and decreased water quality. As the effect of this problem, it is necessary to manage and …
ABSTRACT Water is the source of life for humans. Along with the increase in population, human activities have also increased and will require more water. This resulted in the use of water required costs in its management. The Pamsimas (Community-Based Drinking Water and Sanitation Provision) program is one of the water supply programs for drinking water customers in Talang Bersemi Village. KP-…
ABSTRACT The reservoir has a function as a place to accommodate excess water during the rainy season and will be used to meet water needs during the dry season. The water needs in question include raw water and irrigation water. The Kelarik Reservoir is located in North Kelarik Village, North Bunguran District, Natuna Regency, Riau Archipelago Province. The Kelarik Reservoir is used as an irri…
ABSTRACT Asphalt modification is one way to improve the performance of asphalt mixtures.The material for asphalt modification used can be natural substance such as concentrated latex. Concentrated latex is fresh latex that has been processed and its rubber content concentrated. This study uses concentrated latex as a modified material with the aim of knowing the effect of adding concentrated l…
ABSTRACT The availability of water is very influential for fulfill the basic needs of living things, which is water needs. The water needs of Rokan Kiri Watershed have continuesly increase along with the increase of population, meanwhile the water availability is relatively constant, moreover the quantity and the quality of water getting decrease, and causing various problems. The problems tha…
ABSTRACT Reservoir is a place on the ground surface that is used to store water when excess water occurs or during the rainy season so that the water can be used during the dry season. One of the reservoirs intended to accommodate or store excess water is the Selayar Reservoir located in Lingga District, Lingga Regency, Riau Islands, Indonesia. Utilization of the Selayar Reservoir is intended …
ABSTRACT Productivity is the comparison between the results achieved (output) with all the resources used (input). In general, machine productivity per hour depends on production per cycle, number of cycles, cycle time and work efficiency. In collecting data on productivity, only secondary data is used, namely speed, cycle time, distance, times schedule and heavy equipment data used. On produc…
ABSTRACT Lightweight brick is one of the materials used as a partition wall to replace traditional red brick. The use of lightweight bricks replaces red bricks because they have a lighter weight so the use of lightweight bricks as partition walls will reduce the building's own weight. However, due to its lighter weight, the lightweight brick becomes brittle, affecting its strength. For this re…
ABSTRACT Numerical modelling of helical pile test in peat soil is rarely to be found. The research aimed to analyze the effect of different variation of helical pile spacing, number and diameter using numerical method. Analysis was focused to bearing capacity and failure mode of helical pile in peat soil. Bearing capacity was interpreted with Terzaghi method and Tangent Intersection Method. Th…
ABSTRACT Peat beaches are beaches whose land can be easily abraded than beaches with other types of land. This is due to the light density of peat soil so that it can be easily carried away by the flow of sea water. One of the peat beaches in Indonesia whose coastline has changed significantly in recent decades is the peat beach on Bengkalis Island, Riau Province. Peat samples were taken fro…
ABSTRACT Currently, many companies still use conventional methods as floor slab, where in this conventional floor slab work uses wood as the formwork and take a long time in the process of working on it. In addition, wood is slowly getting harder to get and the price is also expensive. For this reason, we need other technological alternatives to minimize the use of wood. One alternative to woo…
