Abstract

Sunday for Christians and Sunday for Muslims have their own understanding, meaning and history for Islam and Christianity. This is what attracts the writer so that the writer wants to conduct a more in-depth study and analysis through various literature related to Sunday in the view of Islam and Christianity. Based on the background of the problem above, the writer tries to conduct a research using a scientific method. so that it is clearly known "Sunday in the View of Islam and Christianity. The purpose of this study was to find out the views of Islam and Christianity on Sundays, and to find out the similarities and differences of Sundays in the views of Islam and Christianity. This research method is a library research method, namely studying books or references from various literature. The findings as well as the results of this research are that Muslims and Christians have different views about Sunday, wherein Islam in Islam does not recognize Sunday but calls it Sunday where Islam calls it Sunday which means one or one, while Christians call it Sunday. holy day, great day and has various other features regarding Sunday. Muslims and Christians have differences and similarities regarding Sunday (Sunday) where the difference relates to the meaning and meaning of Sunday while the similarity is that Sunday (Sunday) is the same Sama stated that it was the first day of the creation of the universe and from an international agreement that Sunday is an international holiday for all activities, even though Islam has Friday as a special day and a holiday as well as a day of hospitality.

Abstract

PT Pelayaran Lomasasta Pangkalpinang is a company engaged in shipping services and manufacturing workshop services. In supporting the quality of ship components and operational efficiency, the reliability and precision of lathe machines are important factors. This study aims to analyze the effect of variations in cutting parameters on the performance of the Shenyang CW6280B Lathe Machine based on the surface roughness value (Roughness Average/Ra) of the workpiece. The method used was an experimental method by varying three main parameters, namely Spindle Speed, Feed Rate, and Depth of cut. The results showed that all three cutting parameters affected the surface quality of the workpiece. Increasing Spindle Speed tended to produce a smoother surface because the cutting process became more stable. Conversely, increasing the Feed Rate significantly increased the surface roughness (Ra) and became the most dominant parameter affecting surface quality. The Depth of cutalso affected the Ra value, but its effect was not as significant as that of the Feed Rate. The test results showed that the surface roughness values ranged from 1.998 µm to 8.728 µm therefore, the Shenyang CW6280B lathe machine is still considered suitable for use and remains within operational tolerance limits for the repair and manufacture of standard ship components. Based on the evaluation results, the optimal combination of cutting parameters can be used as a reference in machining processes to obtain better surface quality and support the efficiency of maintenance and ship component manufacturing processes at PT Pelayaran Lomasasta Pangkalpinang.
