Abstract

The 4 stroke (4 cylinder) gasoline engine ignition system simulation based on the Arduino Uno microcontroller was designed as one of the modeling of conventional ignition system modification into an electronic ignition system based on the Arduino Uno microcontroller. Conventional ignition systems are modified by removing distributor components and replaced with microcontrollers as ignition system controllers. Spark plug and coil cables are replaced with Igniton coil that uses Igniter. Arduino Uno microcontroller is used as a controller that receives signals from the optocoupler sensor and activates the module relay so that the electric current enters the Ignition Trigger, the voltage needed by Igniton Trigger is 2 V by using a step down transformer to reduce the voltage. So that the Ignition Coil is active and produces a high voltage so that it can produce sparks on each spark plug. This Arduino Uno microcontroller processes data received from an optocoupler sensor

Abstract

Press tool is a press tool used to cut or form a thin plate into the desired shape with a pressing or press machine. This press tool is designed to be able to produce goods in bulk with a relatively short processing time without reducing the quality of the product, so that work efficiency can be improved and can reduce production costs. The design of the press tool for making cylinder head gaskets (3XA - E 1181 - 00) is a Yamaha F1ZR motor with a thickness of 0.5 mm made from ST37 through two processes, namely the embossing process, besides forming, the punch embossing also functions as a stripper. stock), followed by the cutting tool (piercing and blanking) process. Judging from the type of construction, this press tool belongs to the type of compound tool. In the process of making construction products this type has two workmanship functions but in one step work. The force that occurs is the sum of the cutting force (F _p = Us. R_m). The punch center calculation is useful for knowing the center of emphasis. This component is a gas leak retaining plate on the engine cylinder located between the cylinder block and cylinder head.

Abstract

Coconut is a versatile plant and almost all parts of coconut can be utilized by humans. In the processing of coconut fruit, namely stripping, decomposition and sieving, but in the stripping process there are still many uses manually. Therefore, coconut husk peeler is made. This machine can facilitate the stripping of coconut fiber to separate it from the coconut shell. The working principle of this machine is to use knives that are located in the shaft and connected to the motor as a driver by using electric power. The way to do it is that the coconut that has been taken from the tree that is ready to be peeled is placed on the shaft, pressed using a lever to the shaft that has a knife, then the shaft will rotate and the knife will pull the coconut fiber. For the smooth use of coconut coir peeler, proper and efficient maintenance planning is needed so that the engine can run continuously, where the engine components that are treated are shaft, motor, gear, pully and belt. In planned care includes daily, weekly and monthly care. So care must be done well and optimally in order to get good treatment results

Abstract

Water turbine is a tool to convert the potential energy of water into mechanical energy, this mechanical energy is then converted into electrical energy by a generator. Crossflow turbines are radial, small pressurized turbines with tangential injection from fan rotation with a horizontal shaft. The flow of water flows through the pipe entrance, and is arranged by a propeller and into the turbine fan rotation. After the water passes through the turbine fan rotation, the water is at the opposite fan rotation, thus providing additional efficiency. Finally, water flows from the casing either freely or through a tube under the turbine so that it rotates and turns the generator so it can produce electricity. Maintenance of PLTMH is carried out namely preventive maintenance such as; cleaning, lubrication and periodic checks. Maintenance corrections are carried out with the aim of being able to maintain the PLTMH component. Predictive maintenance of a treatment carried out in accordance with the conditions of the PLTMH and predicting damage that will occur in PLTMH

Abstract

The main goal to be achieved is to be able to make an onion slicing machine so that it can answer the problem if the onion slicing is carried out in a larger capacity. The onion slicing machine is made to support the increase in the production of shallot slices, which are ready to be fried for the production of scallion onions in household industries. In a small scale, the work can be done manually with a knife or other simple cutting tool. Problems will arise if large quantities of sliced or cut production are available. In order to facilitate the community in processing shallots and learn about the problems, namely how to produce a shallot slicing machine with uniform slices results using different slope angles on the knife. the working principle of this machine is the Onion which has been peeled dry skin inserted into the funnel then the plate on the back of which has a knife, will rotate because it is driven by an electric motor. As a result of the rotation the onion will be sliced and the slice will fall down, and below it a container will be used as a cross section of the onion which has been finished sliced as a result

Abstract

Starting from the events on the island of Sumatra that often experience forest fires and result in the emergence of smog that can disrupt the respiratory tract in living things, especially in humans. Thus resulting in the emergence of diseases such as ispa, shortness of breath, and other diseases. This is caused by polluted air because the concentration of oxygen (O2) is only a few percent compared to air containing carbon dioxide (CO2), carbon monoxide (CO), sulfide (S2) and other combustion substances. The smoke sensor is useful for activating the fan on the smoke filter tool automatically, the Fan functions as a smoke suction to be forwarded to the room where the smoke is filtered. The workings of this tool are, when the sensor reads the smoke content on the tool more than 140 ppm, then the relay connected to the fan will activate and make the fan spin. After the fan or fan lives, then the smoke will be sucked into a tube, where the tube has a small hose at the end, then the smoke is released at the end of the hose, where the end of the hose is soaked in a container containing water, where the air will be filtered. The results of the filter are sucked back by the fan or fan in another room. If the smoke level has fallen below the threshold of 140 ppm, the fan will automatically die.

Abstract

The power produced by a hydrokinetic turbine depends on the interaction between the rotor and water. Therefore, the optimal rotor geometry must be designed and built to capture maximum water energy and convert it into usable energy. Hydropower is one of the potential renewable energy that can contribute to the need for electricity. Hydropower generator is pollution free so this generator can answer environmental problems and the availability of renewable energy sources. The aim to be achieved in this study is to produce a turbine hydropower with good performance if it operates on an irrigation channel and is applied as a power plant. This research was developed to get the right specifications for the use of hydrokinetic turbines in the irrigation canal area. There are several methods carried out in the design of hydrokenetic turbines, namely by designing blades based on the shape of water flow, repairing the transmission system, and selecting the right generator. In this study, we tested the sweet lemon irrigate applied and tested in the area of ​​Padang Sumbar Sweet Limes Pauh, the results obtained were that the turbine can produce power of about 12.6 watts.
