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…
Abstract In 2020, to improve the performance of the Atha Mapper 2150 fixed-wing, the Mechanical Engineering flying robot team of the Universitas Riau re-designed the Atha Mapper 2150. The research process for the second generation of Atha Mapper has been completed at the design stage. The Atha Mapper 2150 Generation II used fiberglass composite material on the fuselage, while the tail and…
ABSTRACT The availability of fossil energy continues to decrease. The consumption in large quantities and high population growth in the future, it will make the supply of fossil energy unable to keep pace with the demand for energy needs. This encourages the Government to continuously increase the role of new and renewable energy. One of them is empty fruit bunches of oil palm, where its …
ABSTRACT CV. Mutya is an SME scale company (Small and Medium Enterprises) which is engaged in wood processing of wooden pallets. Among companies, the production of wooden pallets is used as storage for logistics goods. The problem that occurs in this company is the amount of productivity that does not meet the target demand. This happens because the distance of the Material flow is far. In…
ABSTRACT Sumber Rezki tofu factory is one of the small and medium business industries engaged in the production of tofu. This study aims to analyze the productivity of tofu production with a lean and green manufacturing approach. The lean manufacturing approach uses VSM (value stream mapping), WRM (waste relationship matrix), WAQ (waste assessment questionnaire), fishbone diagrams, PAM (p…
ABSTRACT PT. Ramajaya Pramukti is one of the agroindustry companies that produces products in the form of Crude Palm Oil (60 tons/hour) and palm kernel (kernel). This study aims to analyze the productivity of CPO processing using Lean and Green Manufacturing. The research method uses value stream mapping (VSM), fishbone diagrams, process activity mapping (PAM) to analyze CPO processing pr…
ABSTRACT Tribology is the science that deals with friction, wear, and lubrication of surfaces in the relative motion of objects. In machining, mechanical contact is unavoidable which causes components to experience friction and wear. The Pinon- Disc Tribometer is a friction and wear test tool consisting of a pin and a disc. Lubricant is a solution to reduce friction and wear. The Pin-on-Di…
ABSTRACT Benefits from waste the oil palm trunk is biomass. The biomass developed from this oil palm trunk is a biopelet. For the production of biopelet, it takes a molding press to make a biopelet which is a biopelet press based on fibers from the palm. This final project was created with purpose modifying a biopelet molding machine In order to mobilise the machines easier and the resulti…
Abstract The use of plastic materials gradually began to shift the use of other materials such as metal, wood, and leather. plastic materials are used in various products ranging from electronic products, automotive, and household appliances. Plastic materials used for automotive and other components that require higher strength reinforced with fibers are known as Composites. Composites fo…

ABSTRACT Every object that moves and comes into contact with each other must experience friction. Friction is a phenomenon that occurs on a surface of contact that moves relative to each other. Friction that occurs continuously can cause wear and tear or loss of particles of an object. There is a science that studies friction, wear, and lubrication, the science is called tribology. There a…
ABSTRACT The failure of the beam pump is something that as much as possible does not happen because the amount of oil production is affected by the performance of the beam pump. The component in the beam pump that often fails is the wrist pin bearing, it is necessary to do a failure analysis to determine the causes and types of failure in the bearing and obtain recommendations for solution…
ABSTRACT Every moving equipment is always damaged. This is due to the presence of two objects that are in contact or rubbing against each other. The main problem faced by the industrial world so far is how to reduce or prevent losses due to friction. This friction can cause damage or loss of particles from a material called wear. There is a science that studies friction, wear, and lubricat…
ABSTRACT Tribology is an interdisciplinary science and technology about the interaction of surfaces in their relative motion. In other words, tribology is the knowledge of friction, lubrication and wear. A pin-on-disc tribometer is a tribometer that uses a pin and a disc as two rubbing surfaces. Friction and wear in the engine elements must be controlled, so that the engine can work optima…
