Abstract

The current becomes a factor influencing the hardness value In the welding. The higher the welding current would affect the higher the hardness test results. If the current were used is low it will make it difficult to ignite the electric arc. Aims of this study to determine the effect of welding current (90, 110 and 130 A) and buffer layer on hardness, macro and microstructure layers are result from hardfacing using AWS A5.13 EFe2/AWS A.51 E7018 elektrodes. The hardfacing process uses a Shielded Arc Metal Welding (SMAW) welding machine with DC+ polarity. Hardfacing consists of three layers, 1st layer uses AWS A5.13 EFe2 electrode, 2nd layer uses AWS A.51 E7018 electrode, and 3rd layer uses AWS A5.13 EFe2 electrode. The increase in hardness will occur significantly after hardfacing on the base metal. The higher welding current is resulting the higher hardness value. The hardness of the 130 A specimen is higher than 90 A and 110 A specimen. In the 130 A specimen the hardness value was 468.1 VHN, and in the 90 A specimen the hardness value was 358.94 VHN.

This training aims to provide knowledge about how to deal with fire hazards and procedures for using extinguishing media when small-scale fires occur. In addition, this training also provides evacuation procedures when a fire disaster causes casualties. After participating in the training, participants are expected to be able to understand, deal with fires and how to properly evacuate victims. so that in general, it can reduce losses due to fire disasters to all levels of society. Abstrak Pramuka merupakan komunitas pemuda yang aktif dalam berbagai bidang sosial masyarakat. Dimana kegiatan pramuka ada pada setiap gugus tugas, baik dari ranting, kelompok hingga tingkat nasional memiliki kegiatan yang selalu berdampak positif bagi para anggota. Berdasarkan banyaknya anggota dari komunitas ini, pelatihan penanggulangan kebakaran untuk Pramuka SMAN I Muara Gembong Bekasi merupakan salah satu pendekatan untuk meningkatkan pengatahuan pada masyarakat. Pelatihan ini bertujuan untuk memberikan pengetahuan tentang bangaimana cara penanggulangan bahaya kebakaran serta tata cara penggunaan media pemadaman ketika terjadi kebakaran sekala kecil. Selain itu, pelatihan ini juga memberikan tata cara evakuasi Ketika bencana kebakaran menimbulkan korban jiwa. Setelah mengikuti pelatihan, peserta diharapkan dapat memahami, menanggulangi kebakaran hingga cara evakuasi untuk korban secara benar. sehingga secara umum, dapat mengurangi kerugian akibat bencana kebakaran kepada seluruh lapisan masyarakat.
