Oil palm plantations in Riau Province are oil palm plantations with the largest land area in Indonesia. One of the areas in Riau Province where oil palm plantation farmers are located is in Kampar Regency, especially in Tapung Hilir District. In the process of shaving oil palm leaves, the craftsmen still use the manual method, namely by cutting the leaves to leave a stick using a knife. To be a…
Excavator is one of the heavy equipment consisting of undercarriage equipped with arm, bucket, and boom. The manufacture of Riau University laboratory scale excavators was first carried out by previous research in 2004. Where an excavator was created with a pneumatic arm whose movement was still maximum and minimum. Other excavator developments in the study developed swing and undercarriage par…

Kualanamu International Airport is located in Deli Serdang Regency, North Sumatra Province. The development of air transport movements at this airport indicates that the passenger terminal facilities which have an existing area of 118,930 m2 with a capacity of 8.9 million passengers per year are no longer able to accommodate the existing passenger volume. This can be seen from the increase in t…
Traffic congestion is a common issue in urban road traffic, and the resulting traffic jams adversely affect road users. Congestion occurs when traffic approaches the road capacity. HR Soebrantas Road is a collector road connecting the city of Pekanbaru and Kampar Regency. This road has four lanes, two in each direction (4/2)D, and holds the status of a provincial road. Each segment of the road …
In Indonesia, industrial waste such as elastic rubber powder from used vehicle tires and fly ash from power plant waste can be used in construction. Fly ash is a geopolymer substance or alternative adhesive that can be used in place of cement in mortar mixtures. The purpose of this study was to examine the effect of silicate modulus (Ms) variation on the resistance of hybrid fly ash geopolymer …
Concrete is a material that has high strength to withstand loads. One of the uses of concrete in the construction field is as a road pavement which is often called rigid pavement. Rigid pavement is brittle so it cannot withstand large tensile loads, so it requires rubber crumb as an added material. Waste rubber crumb from used tires has good benefits for concrete to increase the strength of con…
Eggshell is a type of solid waste that is mostly produced from the food industry. Eggshell ash produced through the combustion process at 900oC will produce a CaO content of 44.4% so that it has the potential to be a substitute for lime in making cement. This study aims to assess the maximum compressive strength, UPV, tensile strength and shrinkage of concrete with cement substitution using egg…
Eggshells are a waste that is generated in large quantities. In fact, eggshells have potential as a sustainable material in construction because they contain calcium carbonate which can increase the strength of concrete and reduce the use of cement. However, eggshells also have disadvantages, especially in terms of impermeability to water and aggressive substances. These weaknesses can be compe…
The utilization of waste rubber and waste fly ash as basic materials in the manufacture of materials is an effort made to mitigate negative impacts on the environment. Rubber powder waste that is elastic and resistant to high temperatures is derived from old vehicle tire waste. Fly ash from PLTU waste is one of the geopolymer materials or alternative adhesive to replace cement. Both wastes can …
