ABSTRACT Transportation is needed by the people around the Riau inland rivers to bring agricultural and natural products to the market or to other places. The transportation needed by the community is a boat or boat capable of carrying goods in Riau's inland rivers which are relatively narrow, shallow and muddy. One of the river transportation used by the people of Riau is the lane boat, w…
ABSTRACT This study aims to obtain optimum welding results on low carbon steel with variations in electrode angle and reverse polarity direct current welding current with SMAW welding machine with adaptive sliding system two axis with speed control. Welding is done automatically and the welding speed is adjusted using the Speed Control. The method used is experimental by varying the electr…
ABSTRACT Rotary friction welding is a type of friction welding which is a type of solid state welding where the welding process is carried out in a solid phase. The friction welding process occurs as a result of the direct conversion of mechanical energy in the form of friction into thermal energy. The process of friction between two surfaces of objects occurs in axial direction pressure. …
ABSTRACT Transmission is one part of the power transfer system that functions to get variations in moment and speed according to road conditions and loading conditions, which generally uses a gear ratio. The basic principle of transmission is how to change the rotational speed of a shaft to the desired rotational speed. Automatic transmission or known as CVT (Continuous Variable Transmissi…

ABSTRACT The strength of the pipe can be seen from test which is carried out by applying a compresive load to the cross section of the pipe, one of the tests carried out is by a pressure test given by a press machine. The manufacture of a hydraulic press machine with an electric motor drive is made to (1) Obtain a hydraulic press machine with an electric motor drive, for pipe testing. (2)…
ABSTRACT Dent defect is one type of mechanical defect that occurs a lot in pipes and other process equipment. The failure criteria used in this defect is no longer based on voltage-based analysis, but because there has been a change in shape (crossing the elastic boundary of the material), the phenomenon of dents in the pipe due to blunt force trauma to the pipe. Therefore, it is needed to…
ABSTRACT Hydraulic jack is one of the simple machine used to lift weights to the desired position with a small force. In the existing briquette press tool, hydraulic jacks are also used for mold presses. The hydraulic jack used previously had been paired with a pressure gauge but there was a leak. Therefore, to maximize the jack work at the same time can provide information on the size of t…
ABSTRAK The engine test bed is a laborious device that passes fuel to the vassel measure, and then from the fuel gauge is piped to the carburetor before entering the engine room. Fuel consumed time is calculated by a stopwatch, while air goes into the carburetor after passing the orifice plate that can be seen on diferential manometer. Loading on the engine is done by the tromol by pressin…

ABSTRACT Multicopter is also called a multirotor because of the number of motorbikes that are more than one, generally multicopters are used for military needs, mapping needs and are currently widely used in photography needs. One type of multicopter is a hexacopter. Hexacopter is one of the unmanned aircraft whose lift is generated from six motors mounted crosswise, the advantages of a he…

ABSTRACT A quadcopter is an unmanned flying vehicle whose lifting force is generated by the spin of the propulsion motor. One type of multicopter that is widely used to perform aerial mapping missions is the quadcopter type. In this study was designed to build a quadcopter frame structure that is able to support flying missions with MTOW quadcopter flying vehicles of 5 kg with a payload of…

ABSTRACT The amount of fuel production that is less than the amount demanded by the world community causes the fuel supply to be expected to run out of stock. Therefore, various efforts were made to save fuel consumption. Not only focus on efforts to discover new and renewable energy, but also focus on efforts to use energy that is efficient. Fuel savings can be done by reducing the weight…
ABSTRACT Broiler chickens will grow optimally if supported by appropriate environmental factors. one of the influencing factors is a comfortable ambient temperature. This temperature can be met by providing a heating device, on the other hand, the use of a heating device will increase the operational costs of maintenance. The purpose of this final project is to obtain a heating device that…
