Abstract

Proses pengelasan dalam industri perkapalan merupakan proses yang sangat penting terutama dalam pembangunan kapal baja. Juru las sudah harus memiliki kualifikasi sebagai juru las. Pada saat proses sertifikasi biasanya juru las sering merasa sudah memiliki kualifikasi, namun kenyataannya juru las belum memiliki kualifikasi. Sehubungan dengan itu, banyak juru las mendapatkan keahlian mengelas dari internship atau kerja magang. Penilaian kemampuan untuk mendapatkan sertifikat kualifikasi masih diperlukan. Sistem monitoring pelatihan pengelasan profesional saat ini masih menggunakan sistem konvensional sehingga kurang efektif. Penelitian tugas akhir ini bertujuan untuk merancang sistem monitoring pengelasan jarak jauh menggunakan wearable sensors secara real-time. Wearable sensors yang digunakan meliputi sensor accelometer, gyroscope, dan magnetometer. Sensor digunakan untuk mengetahui pergerakan khas juru las selama proses pengelasan. Ada empat tahapan yang dilakukan dalam penelitian ini. Pertama, dilakukan observasi sistem monitoring pelatihan pengelasan saat ini. Kedua, perancangan sistem monitoring pelatihan pengelasan jarak jauh secara real time menggunakan sistem aplikasi android dan website. Fungsi dari aplikasi android untuk mengambil data dari wearable sensors dan mengirimkan data ke website. Fungsi aplikasi website yaitu untuk database dan memvisualisasikan grafik dari data sensor yang dikirim agar bisa dilihat di monitor. Ketiga, pengambilan data berupa data non pengelasan yaitu data yang berhubungan dengan data teknis seperti data fitur indikator baterai dan delay pengiriman data. Data pengelasan didapatkan dari perlakuan pengelasan jarak jauh dan dekat dengan pengelasan pelat straight, weaving, 1F, 2F, 3F, 1G, 2G, dan 3G. Proses pengambilan data monitoring dengan pengelasan jarak jauh dibantu dengan video conference (Zoom atau video call via WhatsApp) untuk memastikan juru las melakukan pelatihan pengelasan dan mencatat aktivitas kegiatan pengelasan. Keempat, analisis dan pembahasan mengenai sistem yang telah dibangun. Hasil yang didapatkan pada data non pengelasan yaitu fungsi dari fitur yang dibangun dapat berfungsi dengan baik dan didapatkan delay pengiriman data sensor-sensor dengan rentang satu-dua menit. Data pengelasan yang di-monitoring secara jarak dekat dan jauh menunjukkan adanya data yang tidak terkirim secara sempurna. Hal ini disebabkan oleh terputusnya koneksi internet atau terputusnya koneksi antara wearable sensors dengan aplikasi android sehingga tidak bisa mengambil data dengan baik. Berdasarkan hasil uji coba, koneksi internet yang dapat disarankan untuk digunakan yaitu pada range ping internet dibawah 100 ms dengan kecepatan internet up dan down 2Mbps. Oleh karena itu, penelitian tugas akhir ini diharapkan dapat memberikan manfaat dalam proses monitoring pelatihan pengelasan jarak jauh sehingga lebih efektif dan efisien.

The welding process in the shipbuilding industry is very important, especially in the construction of steel ships. Welders must have the qualifications of a welder. During the certification process, the welder usually feels that he already has the qualifications, but in reality, the welder does not yet have the qualifications. In this regard, many welders gain welding expertise from internships or apprenticeships. An assessment of the ability to obtain a qualification certificate is still required. The current professional welding training monitoring system still uses a conventional system, making it less effective. This final project research aims to design a remote welding monitoring system using wearable sensors in real time. Wearable sensors used include an accelerometer, gyroscope, and magnetometer sensors. The sensors are used to determine the typical movement of the welder during the welding process. There are four stacks carried out in this research. First, the current welding training monitoring system was observed. Second, designing a real-time remote welding training monitoring system using an android application system and website. The function of the android application is to retrieve data from wearable sensors and send data to the website. The function of the website application is to database and visualize graphs from the sensor data sent so that it can be seen on the monitor. Third, data collection is in the form of non-welding data, namely data related to technical data such as battery indicators and data transmission delay. Welding data is obtained from remote and near welding treatments with straight plate welding, weaving, 1F, 2F, 3F, 1G, 2G, and 3G. The process of taking monitoring data with remote welding is assisted by video conference (Zoom or video call via WhatsApp) to ensure welders conduct welding training and record welding activities. Fourth, analysis and discussion of the system that has been built. The results obtained on non-welding data are the function of the features built can function properly and the delay in sending sensor data is obtained with a range of one-two minutes. Welding data that is monitored closely and remotely shows that there is data that is not sent perfectly. This is caused by the disconnection of the internet connection or the disconnection of the connection between the wearable sensors and the android application so that it cannot retrieve data properly. Based on the test results, the internet connection that can be recommended for use is in the internet ping range below 100 ms with internet speeds up and down 2Mbps. Therefore, this final project research is expected to provide benefits in the process of monitoring remote welding training so that it is more effective and efficient.
