Abstract

Reliability Centered Maintenance (RCM) is a process to determine effective maintenance. Dryer Tumbler is a drying machine that has a concentrated air flow pattern and a sealed cylinder rim to ensure the water management system works optimally. This tool is very useful and beneficial especially for laundry because it can produce the highest output in meeting the workload. Repeated component damage occurs in the dryer tumbler machine at Hotel X due to less than optimal maintenance. This is because the maintenance and repair estimates for the existing dryer tumbler machine have not been managed with good and suitable methods. Repeated component interference in the machine makes the machine's performance less than optimal, thus hampering the production process. The production process that is not running optimally causes the resulting product to also experience a decrease in quality. Based on the calculation of component replacement costs, cost savings of 85.17% were obtained for dryer bearings, 2.84% for flatbelts, 58.59% for sizepress bearings and 75.23% for gear couplings.

Abstract

PLTU Teluk Sirih is a coal-fired steam power plant as an energy source that produces ash with a capacity of 2 . The compressor is a medium for transferring ash by using compressed air. The compressor used is a SCREEW OIL INJECTED SULLAIR LS20-150H compressor. Currently there is a decrease in performance on the compressor, which initially had a compression ratio of 1,600 Psia, polytropic head 14,500,599, capacity 10,938,438, flow rate 11,379,622 lb/s, efficiency 98.5%. After analyzing this compressor, the data obtained was a compression ratio of 1,540 Psia, polytropic head 13,805,166, capacity 10,950,733, flow rate 11,392,412, and efficiency of 95.3%. The reason is because the compressor room area does not have an active blower so that dirt/ash stuck to the radiator fins causes heat transfer to be hampered and this greatly affects the performance of the compressor parts to work optimally

Abstract

Current technological advances have produced many products that aim to make human work easier. One of them is an iron burning tool that uses a blower as a tool used to increase or enlarge the air or gas pressure that will flow into the combustion container (furnace). The blower used is a 2 inch snail blower as a tool to increase the air pressure so that the air that is supplied can enlarge the burning flame. The furnace used is a drum coated with heat-resistant cement which can withstand the heat of the combustion fire so that the furnace does not melt. The frame materials used are hollow iron measuring 40 x 40 and angle iron measuring 40x40. For combustion, it uses coal as the main fuel and the blower itself as an air distributor so that it can produce the desired fire. Based on the test results in a metal burning furnace, a temperature of 340°C can be obtained as planned so that by heating the metal, various types of equipment can be formed as desired
