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. The effect of variations in axial loading speed on concrete compressive strength value fc' 20.75 MPa will be tested in this study. This test aims to determine the effect …
ABSTRACT Minimum service standards for toll roads consist of several service substances, namely toll road conditions, average travel speed, accessibility, mobility, safety, aid/rescue units and service assistance, environment, and rest areas. Accessibility is a service measure that must be achieved related to the ease of interaction between toll users and facilities on toll roads, namely t…
