Abstract

Drying is a process of transferring heat and water vapor simultaneously which requires heat energy to evaporate the water content. This heat energy can usually be obtained from sunlight. However, during the rainy season, this condition inhibits the drying process that utilizes sunlight, so the drying process takes a long time. Therefore we need a tool that can dry clothes without depending on the heat source from the sun's rays. The clothes dryer is a tool used to dry clothes with artificial heat energy, one of the artificial heat producers is a heating element or what is often called a heater. The artificial heating element used in this research is Electric Heater. This Electric Heater is equipped with a fan that can produce an indoor temperature of up to ± 52.3º C so that the heat generated by the Electric Heater can convert the water contained in the clothes into water vapor which will then be released into the environment with the help of a fan. Based on the results of calculations and testing, the ability of this tool is able to evaporate an average mass of water of 535.8 grams/hour and this machine reaches its optimum point for the number of drying clothes that can be dried as many as 6 clothes.

Abstract

Alignment is a technique used to maintain machine components that rotate or transfer power so they can operate as effectively as possible and prevent damage to other machine components from errors made during installation or maintenance. Alignment is a maintenance activity that is often carried out on machines in industry and machines within the Morowali Metal Industry Polytechnic, especially in the Mechanical Maintenance Engineering Study Program. Competency in the alignment of gears and bearings is very much needed for prospective mechanics in the industry. The purpose of making this tool is as a simulation tool for learning alignment to achieve straightness and centricity between two rotating shafts (drive and driven shaft) to prevent friction, vibration, and other problems that can reduce tool life and, of course, increase expenditure costs. for repair or replacement of heavy equipment. In the process of designing this alignment tool, a drive method is used in the form of a sprocket and chain, where the link between the drive motor and the shaft to be moved is the sprocket and chain method. This research serves to help produce a design by considering the user's perspective so that the design results can be useful effectively. From the test results, the gear alignment setting tool can function well with the help of an inverter so that motor rotation can be reduced and can be controlled according to the desired conditions. The previous alignment setting tool had an RPM: of 1450.8 and the alignment setting tool that was made had an RPM: of 1455.7 with a frequency of 50 Hz so it can be concluded that this tool can be used for practical work in machine repair and maintenance laboratories.
