Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh temperature temper (TT) dan cooling rate (CR) terhadap sifat mekanik baja paduan rendah. Metode yang digunakan dalam penelitian ini adalah metode eksperimen yang meliputi pengumpulan data, analisis data dengan menggunakan korelasi pearson dan regresi linear. Kemudian dilihat nilai R-squared untuk mengevaluasi seberapa baik model regresi menjelaskan variasi dari variabel terikat. Hasil penelitian menunjukkan bahwa terdapat korelasi negatif yang cukup lemah antara TT dan YS/UTS, korelasi positif yang cukup lemah antara TT dengan EL/RA, dan korelasi positif yang cukup kuat dengan IS. Dari hasil koefisien regresi linear menunjukkan bahwa semakin tinggi TT maka akan semakin rendah sifat mekanik baja paduan rendah YS dan UTS. Namun, hasil regresi linear dengan CR menunjukkan bahwa semakin tinggi CR maka sifat mekanik baja paduan rendah YS dan UTS akan meningkat dan CR akan menurunkan sifat mekanik baja paduan rendah EL/RA/IS.

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

Abstract

An elevator is a vertical transportation device used to transport people or goods. Elevators are box-shaped and are generally used in high-rise buildings, usually more than three or four floors. Elevator specifications are determined by its capacity, speed, and carrying capacity. Elevator selection is based on the use of elevators in buildings with traffic, commuting time, peak time and waiting time in terms of capacity (handling capacity), elevator speed. Adequate quantity of vertical transportation is an important factor, because it will affect the quality of service in a building, so maintenance management is needed that can manage elevator performance. The first step in analyzing component repairs is to use direct observation methods, namely primary and secondary data collection, data processing is carried out to extend the service life of Otis elevators, covering the working principles of Otis elevators, knowing the causes of Otis elevator damage, determining the Otis elevator maintenance schedule and knowing how to properly maintain Otis elevators and how to minimize damage that occurs
