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…
ABSTRACT With the continued increase in rice productivity in Indonesia, it will certainly be comparable to the rice husks produced. The purpose of adding rice husks in this study was to determine the effect of adding rice husks on the quality of the red brick products produced with variations of 0%, 2%, 4%, 6% 8%, and to reduce the weight of the bricks themselves. Making samples of brick test …
Mendol Island coast is a dynamic area because it is directly opposite the Malacca Strait. These dynamic conditions can affect coastal vulnerability. The vulnerability of Mendol Island to changes in sea level rise is caused by several physical factors at sea and on land. Efforts to prevent the impact caused by disasters in coastal areas can be done by conducting a vulnerability analysis of …
Singkep Island is a coastal area. Coastal areas face various pressures and development and change. Therefore, the coast is always changing, including environmental changes that can be caused by human activities. These changes have an impact on changes in the coastline. Considering the condition of residential areas and access to transportation such as roads on the coast, this is considered…
ABSTRAK Coconut shell ash is waste generated from the process of burning coconut shells from the coconut shell industry. Coconut shell ash has the potential to be developed as a partial substitute for cement in the manufacture of mortar because coconut shell ash contains silica which can react with lime to produce CSH which is like cement so as to increase the compressive strength of the morta…
ABSTRACT 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.
