ABSTRACT The abundance of solar energy received can be utilized as a source of renewable energy. The potential of solar energy in Indonesia reaches an average of 5.67 kWh/m2/day. The potential for solar energy is more than 400,000 MW and only about 10,000 MW has been utilized or about 3% of the existing energy potential. It is necessary to develop further regarding the use of solar energy usin…
ABSTRACT Roundness Measuring Tool is a machine that is used to make measurements that are shown to check the roundness of an object or to find out whether an object is really round or not when viewed carefully using a measuring instrument. In carrying out measurements, it must be supported by technology that can make it easier for operators to use and analyze measurement results by involving p…
ABSTRACT Solar chimney power plant (SCPP) is part of the form of solar thermal collector technology. SCPP has the working principle of absorbing solar thermal energy using a glass collector, then converting hot air that flows into electrical energy through a turbine. Converging lenses can increase the output power. This is because the converging lens can focus or focus the intensity of the …
ABSTRACT In structural analysis many problems are too complex to be solved analytically. The Finite Element Method is one of the numerical procedures to solve this problem. The MEH solution requires quite a lot of repeated calculations so that computer assistance is needed. Currently, there are many MEH-based applications such as SAP 2000, MSC/NASTRAN, ALGOR, CAEFEM, ABAQUS, PATRAN, ANSYS. How…
ABSTRACT Solar chimney power plant (SCPP) is an efficient and environmentally friendly renewable energy by utilizing solar energy as its main source. Based on the obtained hypothesis, the use of concentrating lenses can increase the temperature inside the solar collector. With increasing temperature, the speed of air to rotate the turbine blades will increase, so that the power obtained wi…
ABSTRACT The application of the Finite Element Method as one of the numerical methods to solve various engineering problems is of course inseparable from the development of computers with various other related fields such as Computer Aided Design (CAD) and Computer Aided Engineering (CAE) which continuously becomes a concentration of interest in the engineering field. Element analysis has …
ABSTRACT The vertical roundness measuring instrument is a tool used to make measurements that are shown to check the roundness of an object or to find out whether an object is really round or not when viewed carefully using a measuring instrument. The vertical roundness measuring instrument has several main components, namely the chuck as a place to put the test object where the chuck rot…
ABSTRACT The rotary friction welding method is a new method in the welding process. As with welding in general, the welding process with the rotary friction welding method uses friction energy that turns into heat to join two metals. This type of method has a source of heat energy produced by the friction of the material being joined. Where two metallic materials, whether similar or not, a…
ABSTRACT UAV Atha Mapper 2150 is a fixed wing type flying vehicle that can only fly for 30 minutes. Limited cruising time is influenced by several factors, namely the relatively low coefficient of lift force (Cl), as well as the air resistance (drag) that works along the fuselage is relatively large. This research aims to produce Atha Mapper 2150 UAV wing design with greater Cl value and l…
ABSTRACT Friction welding is a type of solid state welding in solid phases as a result of direct conversion of mechanical energy in the form of friction into thermal energy. Friction welding can be done using homogeneous or different types of materials. In friction welding using different types of materials it is difficult to get optimal results due to differences in crystal structure, che…
ABSTRACT Various types of bananas with good quality thrive in various regions in Riau. Banana fiber has good potential to be developed as an engineering material by engineering composite materials. Fiber processing is treated in the form of an alkaline treatment using 5% NaOH for 2 hours, this treatment is carried out to increase the bond between the matrix and the filler. Composite produc…
ABSTRACT Wheelchairs are tools for humans who experience illness, disabilities, and injuries that cause walking difficulties. There are many types of wheelchairs on the market, while wheelchairs that function to help users defecate flexibly have not been widely sold in the market. Therefore, it is necessary to develop a flexible and multifunctional wheelchair that can assist the users in c…
