Abstract

Pengujian ultrasonik tidak merusak ialah pengujian yang memanfaatkan pantulan gelombang suara dari media tertentu. Metode tersebut digunakan untuk mengetahui lokasi dan besarnya cacat dalam benda uji. Akan tetapi, pada umumnya, gelombang suara yang merambat akan melemah semakin jauh dengan jaraknya. Pelemahan gelombang suara yang terjadi dapat digambarkan dalam bentuk kurva yang disebut kurva distance amplitude correction (DAC). Untuk mendapatkan kurva DAC dibutuhkan blok kalibrasi dimana terdapat beberapa lubang cacat buatan atau cacat referensi didalamnya. Blok kalibrasi pada umumnya ada dua bentuk yaitu piping dan non-piping mengikuti standar ASME V. Kali ini, kurva DAC didapatkan dari blok kalibrasi non-piping yang dibuat dan dapat digunakan sebagai acceptance criteria untuk pengujian ultrasonik pada spesimen sambungan las pipa bentuk T serta akan digunakan sebagai perbandingan dengan kurva DAC dari blok kalibrasi piping untuk mengetahui apakah adanya perbedaan dari hasil yang akan dijadikan kesimpulan atas keunggulan diantara kedua blok kalibrasi tersebut. Hasil dari penulisan ini juga hendaknya menjadi pemahaman dan alat bantu untuk meningkatkan pengetahuan teori dan praktik terutama dalam modul Pengujian ultrasonik tidak merusak.

Abstract

Thrust and Moment Meter (TMM) is an instrument for measuring thrust and moment or torque produced by a small electric propulsion system, which is usually used on Unmanned Aerial Vehicles (UAV) and/or small size Radio Control (RC) aircraft. This tool is designed with low-cost materials and simple process, namely Acrylonitrile Butadiene Styrene (ABS) plastic using 3D printing technology. The main component of this device is an Arduino Nano microcontroller, equipped with three Load Cell sensors and one LCD screen. The results of this research are that the TMM tool has been successfully created and tested for accuracy in several cases, and very good results were obtained where the force measurement accuracy was more than 99% (error < 1%).

Abstract

This program is aimed for teachers from SMK N 12 Bandung. Through this PKM (Community Service Program), it is expected that the training participants will gain insights and enhanced knowledge regarding aircraft maintenance, particularly the maintenance of gas turbine engines. The training was conducted at the Propulsion Laboratory, Aeronautical Engineering Hangar, Department of Mechanical Engineering, from October 12 to 16, 2021. The aircraft engine maintenance training began with a pre-test to assess participants' initial knowledge of aircraft engine maintenance. At the end of the training, a post-test was conducted to measure the improvement in their understanding and knowledge. The outcome of this PKM activity is a certificate of participation in the aircraft maintenance training, specifically focused on gas turbine engines.
