ABSTRACT Lubricant is an important thing in the working system of the machining. Without the use of lubricants, it will cause friction and cause wear and tear so that energy is wasted and component life is reduced. The types of lubricants that are widely used are synthetic lubricants and mineral oil which are difficult to decompose by the environment, causing environmental damage, and their so…
ABSTRACT Mechanical contact on an object that gets a load or thrust will cause friction. Friction between objects if it occurs continuously causes wear. Bearing is one of the elements that must avoid friction because it can affect the life of the element and the work efficiency of the machine. One way to slow it down is to use lubricant. The science that studies the problem is tribology. Wear …
ABSTRACT Fossil fuels are running low and are expected to run out, so the world needs renewable energy. Biomass from Empty Fruit Bunches (EFB) is one of the potential renewable energy. In previous studies, peat water was used to reduce potassium (K) so that potassium oxide (K2O) decreased which can cause slagging and fouling, and torrefaction methods to increase the heating value. Chlorine cau…
Abstract The process of planting rice in general is still done manually, especially as rice planting is carried out by farmers in the Salimpaung District, Tanah Datar Regency, West Sumatra. Planting is usually done by 1-3 people depending on the area of the rice field to be planted with an average spacing of about 23-27 cm. The scarcity of labor in agriculture, especially planting workers, is …
ABSTRAK A tribometer is an instrument used to measure a tribological quantity consisting of the coefficient of friction, frictional force, and volume of wear between two materials in contact with each other. This final project aims to manufacture and assemble a gear type tribometer and determine the effect of oil (lubricant) on gears. Generally what is related to the Tribometer is testing on ma…
The porang chopper machine plays an important role in the flouring process, porang tubers that have been cut or commonly called porang chips will dry quickly so it doesn't take a long time. At present, many home industries use a simple method, namely using manual cutting tools so that it requires a lot of energy and a long time. This final project aims to obtain a porang chopper machine wi…

ABSTRACT The powder mixing/blending process plays an important role in powder metallurgy because the uniformity of the powder mixture greatly affects the quality of the resulting product. The aim of this final project is to make a metal powder mixer that can be used for powder metallurgy processes. Mixing speed on this machine is controlled using a 12V 110 rpm DC motor. The working principle o…

ABSTRACT The process of filtering soybean pulp to separate tofu water and dregs in the tofu-making home industry is still carried out in a traditional and less efficient way. Though this process affects the taste, quality and quantity of tofu produced. Need to apply simple technology in the screening process. Centrifugal filtering can be applied to separate soybean pulp and dregs using the cen…

ABSTRACT Gate valve is a machine element that is commonly used to control the flow of fluid and gas at high pressure, so that in the process of making a gate valve it is necessary to pay attention to design characteristics. This study aims to obtain a gate valve design using the Quality Function Deployment (QFD) method. Data was collected by distributing questionnaires and conducting interview…
ABSTRACT In the case study at UKM, Wardi Tahu still uses a 25 kg paint bucket filled with water as the weight. This study aims to design a pneumatic system tofu pressing machine using the quality function deployment (QFD) method and obtain the design characteristics of a pneumatic system tofu pressing machine as desired by UKM Wardi Tahu. In the design of the pneumatic system tofu pressing…
ABSTRACT To improve the performance of the fixed wing flying vehicle, in 2021 the Mechanical Engineering Flying Robot Team of the University of Riau again redesigned the SSU-01 fixed wing type of VTOL flying vehicle. The design process for the SSU-01 VTOL fixed wing flying vehicle has been completed at the design stage. The second stage of the design of the fixed wing VTOL vehicle is the manuf…

ABSTRACT Petroleum production shows a downward trend. Biodiesel is a renewable energy source that can be an alternative fuel similar to conventional (fossil) diesel oil. The use of biodiesel in diesel engines is still experiencing problems and results in the performance of diesel engines not being optimal. Several ways that can be use to improve engine performance in the use of biodiesel inclu…
ABSTRACT Currently, the supply of fossil energy such as oil in Indonesia, which has been used so far, is running low. Therefore, efforts are needed to find renewable energy. One alternative fuel that is environmentally friendly and comes from renewable resources is biodiesel. The biodiesel used is generally mixed with diesel, which is called biodiesel, each biodiesel-solar mixture will have it…
ABSTRACT Fulfilling the need for electrical energy that is not optimal, especially in rural areas, makes it difficult for people to be able to carry out activities like other communities, such as in other areas where electricity has entered the area. The Portable Screw Turbine is a small-scale power plant, where this turbine works by utilizing low head water flow and high water discharge to pr…
ABSTRACT The increasing amount of plastic waste is causing problems for the environment, due to the non-degradable nature of plastic in the soil. One of the plastics that are widely used in everyday life is polyethylene terphthalate (PET). It takes decades in the soil to decompose the wastes from these plastic materials. Another alternative for handling plastic waste is the recycling process w…
