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 …
Abstract Currently, many wood industries have not seriously thought about how to handle the increasingly abundant waste of wood chips, especially the large-scale wood processing industry. small, so far wood waste is not taken into account but is only used as low-value products such as household fuel, burning red bricks and so on, this portable wood lathe uses a hand drill as the driving mo…

ABSTRACT Based on the implementation of the unmanned fast boat contest (KKCTBN) the propeller of fast ships is one of the main factors for the success of the ship propulsion system. The design of the optimal drive system is an important design process. Therefore, there is a need for a design analysis study of the propulsion system to determine the performance of the propeller blades variat…
The objectives of this research are to analyze energy and exergy in the operation of collecting and shipping crude oil which is one of the operating processes in the Upstream Oil and Gas Industry that requires energy consumption at a large cost. The decline in oil production and the large operating costs at CPP Block BOB PT. Bumi Siak Pusako-Pertamina Hulu caused a reduction in company pro…
ABSTRACT Electrical energy is a very important supporting factor for the overall development of a nation, so that industrial and population activities, the need for electrical energy also increases. There are several factors that affect the availability of electricity in Indonesia, including the availability of primary energy and fuel prices. Many efforts have been made in energy efficienc…
ABSTRACT In 2020, the National Unmanned Fast Boat Contest (KKCTBN) was held with the theme "maritime technology in handling Covid-19" which is one of the important agendas for the student sector at the National Achievement Center, Ministry of Research, Education and Culture of Indonesia, in terms of developing innovation. maritime technology to take part in the idea of overcoming the COVID…
ABSTRACT In this study, damage to the pipe was detected using a voice signal and eight microphones. The voice signal method is a smart structural health monitoring that can detect damage at a lower cost. Sound excitation is given using a loudspeaker and the response of the sound signal is sampled using eight microphones connected to a PC-Oscilloscope which functions to convert the analog …
ABSTRAK Composite material is a new type of engineered material consisting of two or more materials where the properties of each material are different from one another. Composites are composed of 2 main materials, namely the matrix which is the phase in the composite, has the largest part or volume fraction in the composite which functions as an adhesive and protector and reinforcement w…
ABSTRACT A dynamometer is a machine that is used to measure torque and rotation produced by a motor engine or other rotary drive. The working principle of a dynamometer is to rotate a shaft that has a disc located in a housing containing an electromagnet coil. When current passes through the coil, it creates a very large magnetic field in the disc, this will also produce a current that rot…
