The quadplane dual-system is the most popular fixed wing VTOL concept. The development of fixed wing VTOL vehicles that has been carried out has several obstacles including being unstable during the t…
ABSTRACT Every country is racing in developing renewable energy potential with the natural resources they have, this is because renewable energy can be a sustainable and environmentally friendly energy supply. The Vortex turbine is one of the hydropower generator turbines which has the potential as a source of renewable energy even on a small scale. The working principle of the vortex turbine …
ABSTRACT Turbine vortex is one of the picohydro power plant water turbines. There have been various studies conducted on turbines vortex, but the efficiency obtained by each researcher has a different value. So the real efficiency of the turbine vortex can not be determined. Therefore the turbine design is carried out vortex to get real efficiency. The design is carried out based on the result…
ABSTRACT Life Cycle Assessment (LCA) analysis is a method used to evaluate the environmental impact of a product or process over its entire life. In this study, LCA was used to analyze the comparative synthesis of Cobalt Glutamic Bio-MOF using two methods, namely the solvothermal method and the ultrasonic method. The purpose of this analysis is to determine the environmental impact resulti…
ABSTRACT Torefaction is a thermal treatment of biomass in the absence of oxygen for 15-60 minutes. Torefaction was chosen because the solid substance produced is 50-90% of the initial biomass and the energy yield is 60-80% of the initial energy. The raw material used is empty bunches of palm oil and the product of torefaction is bio-coal. The torefaction method used is continuous tubular b…
ABSTRACT Global warming caused by greenhouse gases is getting longer and more worrying. Switching from fossil fuels to natural gas is a promising solution, by applying the ANG (Adsorbed Natural Gas) mechanism. An important factor for the success of this mechanism is the selection of the adsorbent used. MOF (Metal Organic Frameworks) has good potential in storing methane gas, but further resear…
ABSTRACT Automation machine technology has been developed to help overcome problems in manufacturing performance. One of the machines developed is the delta type 3D printer machine which can be used in various professional fields. In designing a delta robot, several things need to be considered, one of which is the singular condition of the delta robot. This is so that the delta robot can oper…
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…
