Friction Stir Welding was first introduced by The Welding Institute of UK 1991 as a solid joint technique. Application of Friction Stir Welding on polymeric materials and states that FSW technology can be applied to polymeric materials. The purpose of this study is to analyze the results of temperature measurements on the geometric angle of the pin tool on friction stir welding, then validated …
Biodiesel is an alternative fuel that is used as a substitute for depleting fossil fuels. Biodiesel has different characteristics than fossil fuels, so changes to the engine are needed to improve engine performance. One way to improve engine performance is to vary the fuel filter mesh with sizes of 2, 10, and 30 microns. This study uses B40 and B50 fuel with engine rpm of 2500 kg/m2, 5000 kg/m2…
Along with the increasing consumption of domestic diesel fuel oil with an average consumption rate of 5% per year and production of only 75% of the total demand, the reserves of fuel are getting depleted from year to year. There are many alternatives that can be done to overcome the reduced availability of petroleum. One of them is to use a mixture of vegetable oils into pure diesel, which is c…
This study aims to optimize the machining parameters in the production process of the Yamaha motorcycle brake piston master cylinder for finishing work and to determine the effect on surface roughness. The method used is the Taguchi method and simulation assisted by Mastercam 2018 software (CNC lathe). Machining parameters were varied based on the Taguchi method, each of which applied a machini…
ABSTRACT Biomass is a renewable fuel and generally comes from living things (non-fossil) in which energy is stored. In theory, Indonesia's biomass energy potential is estimated at around 49,810 MW. This figure is assumed on the basis of the energy content of the annual production of about 200 million tonnes of biomass from agricultural, forestry, plantation and municipal solid waste residues. …
ABSTRACT Definition of Centrifugation or centrifugation technique is a mixture separation technique that is carried out by utilizing centrifugal force. This technique is most often used when dealing with the field of biochemistry, particularly in the separation of macromolecules or colloids from other liquids. In theory, centrifugation utilizes centrifugal force where this centrifugal force is…

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…
