One of the work activities usually carried out to maintain and repair public facilities in residential communities is the welding process. Of course, correct knowledge is needed regarding a good welding process in order to produce quality welding results so that the object being repaired can last a long time. In the welding process there are several potential dangers which have risks both for the welding worker himself in terms of health and risks for the environment in the form of fire. Education to the public regarding the welding process so that it produces quality results in general includes: ensuring the work area is clean and safe, then the tools and materials used are according to specifications and correct welding techniques are very helpful to the public. Apart from that, recognition of the potential dangers and risks that may arise from the welding process can increase awareness in the community of the importance of implementing occupational health and safety principles.

In the world of the PLTU industry, the need for material, especially the need for the sapot process and conveyor repairs, occurs in the world of PLTU, which is installed on the conveyor construction and when connecting materials, different grades are often used and this often occurs in the field during the process of combining plates with different grades. on the sapote. and for installing the plate on the sappot, use grade A and the plate that is often used is the plate for the machine foundation with grade B on the sappot material using low carbon grade A steel. In this research report, welding is carried out and combined with grade A steel which is usually used for sappots. the conveyor is combined with low carbon grade B steel in the construction of the PLTU sapot. Where welding is carried out 3x why this needs to be done is because to know the characteristics of low carbon grade A steel and low carbon grade B steel, whether the characteristics are the same or not because they are used in When grade A steel material runs out in the industry, the testing process uses 3 tests, namely to determine NDT testing (Non Destructive, test), tensile testing, and micro testing for the testing process.

Welding is an important thing in shipbuilding. There are several types of joints and types of materials with different material thicknesses, on of which is Flux Cored Arc Welding (FCAW). FCAW is a welding process that has a high level of productivity so that it is suitable for fabrication activities. Double-sided welding is often performed on joints. This causes time inefficiencies and costs quite a lot. Therefore, the solution so that welding is only done on one side, by using a backing ceramic. The Backing Ceramic is used to hold the welding penetration better and get better welding result. The purpose of this study was to determine the result of the strength of Backing Ceramic Weld on FCAW welding of A36 carbon steel material so that it can get perfect results, not defective and can be accepted according to the desired criteria.

Di negara indonesia ini, permasalahan ketenagakerjaan ini memiliki berbagai permasalahan, di antaranya ialah kepercayaan diri yang kurang, kualitas tenaga kerja yang rendah serta lapangan pekerjaan yang sulit hingga berimplikasi terhadap krisis global. Namun, tidak melibatkan upaya pengembangan sumber daya manusia yang bertalenta dan berdaya saing di tengah permasalahan yang kompleks. Kondisi kondisi kerja di Indonesia tentunya akan semakin memburuk. Dengan demikian, segala bidang perlu pembenahan diri baik dari segi kualitas maupun kuantitas pekerjaan, salah satunya adalah bidang teknologi las. UPT Praktek Kerja Kabupaten Deli Serdang, sebagai instansi pemerintah yang mengadakan beberapa jenis pelatihan,  yang di antaranya ialah berupa teknik pengelasan, yang mana ini dianggap akan dapat menyebabkan proses dalam mengembangkan sektor ketenagakerjaan ini semakin cepat. Penelitian ini tujuannya ialah agar dapat mengetahui pelaksanan dari pelatihan untuk keterampilan dari las listrik untuk menaikkan persaingan dan kapasitas dari para tenaga kerja tersebut. Jenis penelitian ini terintegrasi secara kualitatif dan kuantitatif. Topik penelitian sebanyak 10 responden, terdiri dari 10 peserta pelatihan. Observasi, wawancara, kuesioner dan dokumentasi sebagai sarana pengumpulan data, dan data yang terkumpul ini dilakukan pengolahan dan penganalisisan dengan mempergunakan rumus koefisien korelasi product-moment. Hasil survey menunjukkan bahwa pelatihan las memberikan pengaruh signifikan terhadap kualitas tenaga kerja masyarakat dalam peningkatan kualitas tenaga kerja masyarakat di Balai Pelaksana Teknis Balai Latihan Kerja Kabupaten Deli Serdang.

PT. XYZ, sebuah perusahaan manufaktur, memproduksi berbagai produk, termasuk Bok Travo. Perusahaan bertujuan untuk mengurangi limbah dalam proses produksinya untuk meningkatkan keuntungan dan tetap kompetitif di industri. Untuk mencapai hal tersebut, sebuah penelitian dilakukan untuk mengidentifikasi, mengurangi, dan mengusulkan perbaikan limbah dalam proses produksi Bok Travo. Studi ini menggunakan konsep lean manufacturing dengan menggunakan alat pemetaan aliran nilai dan metode Failure Mode and Effect Analysis (FMEA). Hasil pemetaan aliran nilai menunjukkan bahwa waktu produksi Bok Travo dapat dikurangi dari 2559 menjadi 2159 menit. Dengan menggunakan metode FMEA, akar penyebab pemborosan tertinggi diidentifikasi sebagai cacat seperti permukaan material yang tidak rata, kebocoran, kerataan, dan goresan pada produk. Rekomendasi perbaikan yang diusulkan antara lain penambahan waktu pengelasan dan pemberian support selama pengelasan, serta pengecekan silang dimensi sebelum proses perakitan.
