Abstract

Currently, the energy we use is still using fossil energy. In the future, the need for energy will increase because every year there is a large population growth. If you still use fossil energy and don’t find new energy alternatives, then Indonesia will experience a severe energy crisis and certain places will experience blackouts. One of the efforts so that the wind energy crisis can be minimized is to utilize natural energy that has the potensial to generate energy such as the Wind Power Plant. In this study, planning and simulation of Wind Power Plant were carried out to help reduce the use of fossil energy and help the needs of the community in the Talise Beach area. From the results of the study that the average output of wind turbine production is 1,180/hour winh a maximum production of wind turbines per day of 5,665 kW and the construction system cost (NPC) of Rp. 91,340,660,000. Electrical energy that can be generated from wind turbines by utilizing an area of about 42,021.67 m2 is 10,332,498 kWh/year with a total unfulfilled power of 1,416 kW/year. Lack of power or unmet load can be overcome by the existence of a grid/network.

Abstract

The wind is one of the new renewable energy sources that can be used as a source of electrical energy. But the wind in nature has a speed that varies greatly with each time and place. This can be overcome by using the DC-DC Converter tool with a fuzzy method to produce a stable electrical voltage so that it becomes usable electrical energy. This tool uses a series of converters connected to the Arduino microcontroller. The DC-DC converter circuit in this study also uses a voltage sensor as feedback for the Fuzzy method to maintain the stability of the circuit output which varies from 2V-5V, so that it can maintain a voltage of 6.5V which is used as a 6V battery charging. This circuit has an average efficiency of 60% for the open-loop system and 63% for the closed-loop system.

Abstract

Sun is one of the new renewable energy sources that can be used as a source of electrical energy that is available on the earth. But the sun in nature has a light intensity that varies greatly with each time and place. This issue can be overcome by using the Modification Sepic Converter tool with a fuzzy method to produce a stable electrical voltage so that it becomes usable electrical energy. This tool uses a series of converters connected to photovoltaics. The tool also uses a voltage sensor as feedback for the Fuzzy method to maintain a voltage of 21-23VDC to 48VDC.

Abstract

Utilization of electronic technology in various aspects of human life, both in household needs, education, industry, and human habitation itself. In this discussion is how to design a queuing system based on the Internet of Things using a Raspberry Pi W Zero controller. Internet of Things is a concept in which an object or object is implanted with technologies such as sensors and software with the aim of communicating, controlling, connecting, and exchanging data through other devices while still connected to the internet. In designing this queuing system, a website is needed to support this tool to make it easier for users to register online without having to manually take queue numbers. The programming language used for the Raspberry Pi W Zero controller uses python. Testing this queuing system 100% went well and according to what was designed for the design of an Internet of Things based anti covid 19 queuing system using the Raspberry Pi W Zero. With this tool, it can make it easier for users to register queue numbers and be able to run the appropriate Health protocol system.

Abstract

Noise hazards can occur in almost all work areas and can be sourced from various work equipment. The sound category included in the noise hazard is sound with an intensity of more than 70 dB. In areas where sound has an intensity of more than 70 dB, it is recommended to use hearing protection devices such as ear plugs, while if the sound intensity is more than 80 dB, you must use ear muffs. The work area is usually only given a warning board to use hearing protection equipment, but there is no noise hazard detection device that can give real-time warnings. The purpose of this study is to design a tool that can detect and measure noise levels in a work area. This tool uses the fc-04 tool as a noise level reader which then gives a signal to the Arduino Uno microcontroller which will classify the sound level into 3 levels, namely low, medium and high which are displayed on the LCD board and use 3 LED (green, yellow and red) as an indicator of the level of noise hazard and a warning to use hearing protection.

Abstract

Chips are a type of snack or snack made from tubers such as cassava and bananas which are usually produced by home businesses. However, most home-based chips making businesses still use manual tools such as kitchen knives or cutters so that production takes longer, the thickness cannot be adjusted and the risk of workers' hands being injured by knives is added. This cassava and banana chopper uses a driving motor system that is driven by an electric motor with a speed of 1400 RPM HP and the pusher is driven by a power window. The results of this tool chopping obtained thickness in cassava and banana is 1-1.5 mm which is the standard thickness of chips in general. In addition, the results obtained are faster production compared to manual techniques using a kitchen knife or cutter. The conclusion is that the cassava and banana chopper with a driving motor is very efficient for chip craftsme, because the production time is faster and the thickness of the cassava and banana slices is uniform, namely 1-1.5 mm.

Abstract

Effect of NaCl Immersion Media on Corrosion Rate on ST 42 Steel in Kepok Banana Peel Inhibitor Extraction. This study aims to determine the corrosion rate of ST 42 steel using an inhibitor of kepok banana peel extraction with various NaCl immersion media. Sample immersion time is 168, 336, 504 hours. The method used to calculate the corrosion rate is to measure the weight loss. The sample of this research was carried out in the Mechanical Engineering laboratory, Faculty of Engineering and the Pharmacy laboratory, Faculty of Mathematics and Natural Sciences, Tadulako University. The results obtained in the variation of NaCl 2.5%, 3.0%, 3.5%, 4.0%, 4.5%, inhibitor kepok banana peel extraction 300 ppm, an increase in corrosion rate with increasing NaCl variation with the same amount of extraction inhibitor, this is because the percentage of NaCl variation greatly affects the corrosion rate.
