ABSTRACT Blended concrete is a mixture of aggregate and blended cement. Substitution of cement into mixed cement has an impact on increasing the pozzolanic reaction in cement. The silica content in Palm Oil Fuel Ash (POFA) is the element most needed to increase the reactivity of pozzolans. A treatment is required to obtain pure silica in POFA through the sol gel precipitation process. The cont…
ABSTRACT The relocation of the capital city to the province of East Kalimantan was based on the relatively small potential risk of an earthquake. Based on records, East Kalimantan has experienced a strong earthquake, so the risk of building failure must be considered. In general, structural system failure can occur due to a level that cannot dissipate energy well enough or is referred to as a …

ABSTRACT Bridges are infrastructure buildings that are affected by technological developments. The shear capacity of reinforced concrete beam sometimes cannot meet the existing requirements. This can be caused by increased loads, inadequate shear provisions in the initial design and material damage due to natural factors. Reinforcement methods by means of externally bonded (EB) and near-surfac…
Abstract The increased use of concrete as a building material will result in an increase in the use of cement. The use of cement in very high quantities will have a significant effect on increasing CO2 emissions and global warming. Cement substitution can help to reduce the excessive use of cement. Furthermore, cement substitution can help reduce the residual cement hydration reaction, namely …
Some problem in this research possession of the ball always fails when receiving service from the opposing team, due to a lack of eye-foot coordination, which should be controlled but the ball is not aimed. In addition, the maximum smash power has not yet been reached. This research aims to investigate whether there is a contribution between leg muscle strength and flexibility on smashing sk…
ABSTRACT The success of a project requires the implementation of good management. Good control can reduce the risk of delays and project cost overruns. To improve effectiveness in monitoring and controlling the project, the result value concept method is used. The Result Value Concept Method is able to calculate the amount of costs in accordance with the budget that has been implemented and ma…
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 Melamine is the coating for general or specific purposes such as automotive and paint additives. Melamine is a fine, white, powdered crystal that reacts to aliphatic and aromatic aldehydes into many products. The upcoming trend in the market such as melamine-based foam is likely to provide huge opportunities in the future. In 2018, Indonesia recorded a melamine import number of 32,503…
ABSTRACT Methyl salicylate (C8H8O3) or oil of wintergreen is an organic compound in the ester group in the form of a colorless liquid which has little solubility in water. Methyl salicylate has uses in various industries.
