Abstract

In this paper, an ultrasonic non-destructive test (NDT-UT) has been carried out on steel using the Simulink-MATLAB Mathematica computation method. This study aims to analyze the NDT-UT output signal for material defect detection using secondary data as the first sample. The sample is then analyzed using the fast Fourier transform (FFT) method to produce a spectrum waveform and image thermography. It can be seen that there is a decrease in signal height from 1 a.u to 0.55 a.u. The first sample waveforms were used to analyze the second sample, third sample, and fourth sample, and all the samples had different defects. The results of the sample analysis are in the form of a thermographic image that shows the temperature level based on the distribution of red (R), green (G), and blue (B) images on the sample surface. The NDT-UT output signal produces a sinusoidal wave similar to the results of the Simulink-MATLAB modeling analysis on the initial input echoes and the back wall, with a percentage inequality of 10%. Then validated the sinusoidal signal from the NDT-UT which gave a percentage of inequality between 0% – 42%. More complex or irregular defects result in a larger percentage or vice versa.

Abstract

As a country with a multicultural population composition, the Indonesian population is very familiar with the issues of the halal and unlawful status of food, social etiquette and the practice of tolerance. So, it is very urgent to immediately formulate the theme of Islamic study material as part of multicultural insight lessons such as in the Kembayan District area, Sanggau, West Kalimantan. The aim of this research is to formulate Islamic ideals regarding the etiquette of getting along and being tolerant in the social interactions of Muslim and non-Muslim students so that education can actually become a forum that guides and directs students, especially those who are Muslim, so that they do not fall into negative relationships because they are wrong define the meaning of tolerance. This paper uses a descriptive qualitative research method with a type of library research which examines in depth the library materials that are relevant to the theme of the material being discussed. The main sources for this article are taken from books, journal articles, internet articles and other related writings. The technique used in collecting data in this paper uses secondary data, namely by collecting data indirectly by examining the object in question.
