Abstract Currently, many wood industries have not seriously thought about how to handle the increasingly abundant waste of wood chips, especially the large-scale wood processing industry. small, so far wood waste is not taken into account but is only used as low-value products such as household fuel, burning red bricks and so on, this portable wood lathe uses a hand drill as the driving mo…
Abstract The harvesting process plays an important role in the palm oil industry, especially the separation of oil palm fruit. Separation of oil palm loose fruit aims to separate oil palm fruit based on the quality of maturity. The action that can be taken is making a palm kernel oil separator machine to separate the loose fruit from the bunch. The manufacture of this machine is the result…

ABSTRACT Based on the implementation of the unmanned fast boat contest (KKCTBN) the propeller of fast ships is one of the main factors for the success of the ship propulsion system. The design of the optimal drive system is an important design process. Therefore, there is a need for a design analysis study of the propulsion system to determine the performance of the propeller blades variat…
The objectives of this research are to analyze energy and exergy in the operation of collecting and shipping crude oil which is one of the operating processes in the Upstream Oil and Gas Industry that requires energy consumption at a large cost. The decline in oil production and the large operating costs at CPP Block BOB PT. Bumi Siak Pusako-Pertamina Hulu caused a reduction in company pro…
ABSTRACT Electrical energy is a very important supporting factor for the overall development of a nation, so that industrial and population activities, the need for electrical energy also increases. There are several factors that affect the availability of electricity in Indonesia, including the availability of primary energy and fuel prices. Many efforts have been made in energy efficienc…
ABSTRACT In 2020, the National Unmanned Fast Boat Contest (KKCTBN) was held with the theme "maritime technology in handling Covid-19" which is one of the important agendas for the student sector at the National Achievement Center, Ministry of Research, Education and Culture of Indonesia, in terms of developing innovation. maritime technology to take part in the idea of overcoming the COVID…
ABSTRACT In this study, damage to the pipe was detected using a voice signal and eight microphones. The voice signal method is a smart structural health monitoring that can detect damage at a lower cost. Sound excitation is given using a loudspeaker and the response of the sound signal is sampled using eight microphones connected to a PC-Oscilloscope which functions to convert the analog …
ABSTRAK Composite material is a new type of engineered material consisting of two or more materials where the properties of each material are different from one another. Composites are composed of 2 main materials, namely the matrix which is the phase in the composite, has the largest part or volume fraction in the composite which functions as an adhesive and protector and reinforcement w…
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 In general, every moving object always experiences friction, this friction occurs when there is mechanical contact that works on two components that come into contact. If this friction occurs continuously it will cause some losses, one of these losses is causing wear. There are several factors that affect the value of the wear rate and friction coefficient, such as loading factors…
ABSTRACT The combination punch and bending machine is a machine that belongs to the press type with the use of punch and die. This machine has a hydraulic drive with a maximum pressure generated of 700 bar. While the engine performance is only able to withstand a working pressure of 27.7 bar, therefore the utilization of the working pressure that is owned needs to be increased so that the …
ABSTRACT Spinner food driying is a machine that functions as a drain in the form of water or oil found in food. This final project aims to assist the process of increasing production results in draining the oil from frying food, both on a medium the industrial scale and a household scale (UMKM). This draining machine has main components, namely an electric motor, a shaft, a drum, a pulley,…
ABSTRACT Referring to the results of previous studies related to the detection of injection pump damage using vibration signal analysis, it was found that changes in the vibration signal parameters can be detected as abnormalities of the injection pump condition against normal conditions. Changes in the vibration parameters of the injection pump also result in changes to the parameters of …
ABSTRACT The human need for energy is increasing every time. However, the availability of energy is currently running low, especially energy sourced from fossil fuels. Renewable energy is the main topic of this research, where renewable energy is one of the breakthroughs to deal with the energy crisis. Vibration is one of the renewable energies that can be utilized, including vibrations th…
ABSTRACT The energy crisis is a problem for all countries because the availability and world's fossil fuel reserves are depleting every time. Departing from these problems came the idea to find renewable energy sourced from sound energy. Sound energy has wide availability, such as in roads, airports, markets, industry and so on. In this study, sound energy is captured or harvested using a …
ABSTRACT The plate punching and bending combination machine is a machine that belongs to the press type with the use of a punch and a die to make holes or bends in a plate workpiece. This machine uses a hydraulic drive with a maximum working pressure of 700 bar which is used as a punch force to workpiece, but it is not known how much working pressure this frame can withstand. Therefore, ma…
ABSTRACT This research was conducted to find out how to design an overshot type waterwheel and what is the effect of variations in the diameter of the overshot type waterwheel on work performance, the waterwheel is classified into the category of picohydro power plants that can generate electricity less than 5000 Watt, the overshot type waterwheel has a motion mechanism by using water impe…
