The welding is the process of connecting two metals, where factors that influence are current, voltage, plate thickness, gap shape and heating temperature of the electrode. The heating of this electrode aims to stabilize the arc arising during welding. The objective of the study was to determine the maximum hardness of low carbon steel welding with E 7018, with temperature of electrode storage at temperature 50, 75 and 100 ° C. Determine the maximum change in the hardness of the welded by using heated electrodes preheated to an initial temperature of 50, 75 and 100 ° C. Compare its hardness to the standard. The specimen-making method is based on JIS Z 3121, further data are compared against the standard. The result of maximum hardness value for slit I is 175HV and for slit V 264HV in weld area with temperature 75 ° C, hardness change of 33HV for temperature 100 °C.

Stainless steels are widely used for household purposes, such as spoons, forks and knives that serve as cutting tools are currently widely used. Based on the micron structure this metal is grouped into austenitic, ferritic, martensitic, duplex and prepication hardening. The purpose of writing determines the optimum hardness value of stainless steel 304 after getting treatment with nitrogen media. Gets optimum hardness when using nitric acid media. At what temperature and what type of cooling is used to obtain optimum hardness. Research method by comparing stainless steel before and after experiencing heat treatment process by using nitrogen cooling medium and nitric acid. Hardness testing using rockwell method. Optimum hardness results occur at 400 °C with 20.33HRc nitrogen cooling medium and 500 °C of nitric acidic acid 19,67HRc

The development and revision of milling machines and components are continuous. With the help of computer technology, we can simulate some activities in a manufacturing system. The main purpose of a simulation is to understand and imitate the behavior of a particular manufacturing system on a computer, before hardware creation, thereby reducing the amount of testing and experimentation in the field. By using a virtual system, less material is wasted and the constraints on the actual operation of the machine in the field can be minimized. In the field of milling machinery, various modeling and simulation methods have been introduced so far. Today, the manufacture of a machine tool can no longer use the time-consuming and costly manufacturing and testing of physical prototypes to detect weak points and then optimize the design. In contrast, the current machine tool design process uses "virtual prototyping" technology to reduce the cost and time of hardware testing and iterative improvements to physical prototypes. The model of a milling machine can be simulated in Matlab simulations through analytical methods using various compositions. The presented virtual modeling methods and milling machine tool simulations make it possible to design, perform complex analyses, test, optimize, and use various types of control structures. in the computer simulation. Keywords: Milling Machine, CNC Miling Machine, Matlab

Kondisi perekonomian saat pandemi ini sungguh merosot tajam, hal ini di tandai dengan rendahanya daya beli masyarakat. Hal ini tentunya disebabkan lapangan kerja yang semakin berkurang, sedangkan tenaga produktif bertambah sehingga penganguran semakin bertambah. Untuk menumbuhkan dan meningkatkan ekonomi rakyat, perlu dilakukan penguatan pada industri kecil dan menengah. Salah satunya adalah industry keripik tepung singkong UMKM TIGA DIVA. Tujuan dari pengabdian ini adalah meningkatkan produktivitas kerupuk singkong. Metode implementasi dan pendekatan untuk memecahkan masalah produksi mitra UMKM. Langkah pertama adalah penyesuaian. Dari koordinasi dan diskusi yang berlangsung, lahir enam program strategis untuk mengatasi permasalahan di bidang produksi yaitu: a. Penentuan spesifikasi mesin pengaduk adonan, b. Pengadaan mesin pengaduk adonan. c. Uji coba mesin pengaduk adonan. D. Pelatihan dan pendampingan mesin pengaduk. Sedangkan untuk permasalahan bidang pemasaran, diperoleh program strategis penyelesaian permasalahan bidang pemasaran yaitu perancangan pemasaran berbasis online melalui website dan marketplace. Berdasarkan rancangan penilaian kegiatan, Hasil pengabdian menggambarkan tahapan kegiatan pengabdian penerapan iptek dan pencapaian indikator keberhasilan: Tim layanan menyinkronkan jadwal dan membuat daftar alat dan bahan yang digunakan oleh masyarakat pembuat keripik singkong. Berdasarkan hasil penyesuaian tersebut, tim pengabdian bersiap untuk mendukung pembuatan mesin pengaduk, web and pemasaran, dan pengelolaan UMKM. Lama waktu pengadukan tanpa mesin pengaduk untuk kapasitas 50 kg dibutuhkan 6 orang dengan waktu sekitar 30 menit, sedangkan setelah menggunakan mesin pengaduk hanya butuh 3 orang dengan waktu sekitar 5 menit. Sehingga dapat meningkatan produktifitas umkm meningkat secara signifikan sekitar 2,85 kali dari sebelum adanya mesin pengaduk.
