ABSTRACT Centrifugation is a process that utilizes centrifugal force for the sedimentation of a mixture by means of a centrifugal or dizzying machine. Centrifugal force is the force that occurs due to the presence of rotation, the direction of the force is from the central point of the exit rotation towards the outer radius. The separation between the two liquid phases that make up the emulsio…

Abstract One of the phenomena that occurs in the field of machining is the phenomenon of contact between components. Tribometer is a tool used to determine the wear and friction of a material between two contact surfaces. The Pin On Disc tribometer that already exists in the Mechanical Engineering lab at the University of Riau is driven by an electric motor and uses a regulator as a regulator …
Abstract To improve the performance of the racing plane flying vehicle, in 2021 the Mechanical Engineering flying robot team at the University of Riau again designed the Racing Plane re- vehicle. The design process for the Serindit V-3 vehicle has been completed at the design stage. The second stage of the design of the Serindit V-3 spacecraft is the manufacture and assembly of the Serindit V-…
ABSTRACT The buildup of old documents that are no longer used often occurs in offices and campuses. The old document can be sold to a paper collector but not with its contents. Many of the old documents are confidential which before being sold is required to be cut so that the contents are not known. To cut the paper, a document shredder was made with these 4 blades. The tool consists of sever…

ABSTRACT This study discusses the Performance of an Organic Rankine Cycle with a Capacity of 560 Watts with the Use of Gasoline Engine Exhaust Heat as an Energy Source. ORC is a modification of the conventional Rankine cycle, where in ORC the working fluid is an organic fluid or refrigerant that has a low boiling point, so that at low temperaturs it is capable of producing steam. The worki…
ABSTRACT The demand for energy around the world is increasing gradually as a result of population growth, advances in science and technology. The fossil energy that been used has led to increasing environmental problems such as air pollution, global warming, depletion of the ozone layer and acid rain caused by excessive consumption of fossil fuels. Utilization of renewable energy sources such …
ABSTRACT Atha Mapper 2150 generation II is a UAV vehicle developed by the Serindit Aero Mechanical Engineering team at the University of Riau in 2021 but data regarding the performance of the vehicle has not been obtained. This study aims to determine the performance of the propulsion system and the flying performance of the second generation Atha Mapper 2150 UAV, theoretically and experimenta…
ABSTRACT Fixed wing unmanned aircraft have several weaknesses including requiring a large area for take off and landing, requiring a launcher as an additional tool for take off and having a high crash risk during landing. because the vehicle does not use landing gear. So that the above weaknesses can be corrected, it is necessary to conduct research related to the development of a tail-sitter …
