Abstract

Halal products are products that are starting to be looked at by the market today. One of the goals of the Indonesian government, under BPJPH, in 2024 it is hoped that products, especially food and beverages in Indonesia, will already have halal certificates so that they can increase the attractiveness of pariwasata for Muslims around the world if they visit Indonesia. Based on the new legislation in 2014, namely law no. 33 of 2014 concerning Halal Product Guarantee, the halal certification process is carried out in synergy by various parties, one of which is the halal product guarantee organizing body (BPJPH). Halal product process assistance is a process of verifying and validating halal statements by business actors (self-declare). This activity serves to assist micro and small business actors in meeting product halal requirements. The purpose of this community service is to find out the level of understanding of prospective halal product process assistants in Batam City, service activities are carried out with 3 stages, namely surveys, socialization and training activities and the last stage is evaluation and reports. This activity is supported by BPJPH and Bank Indonesia as additional sponsors for activities to be carried out offline and online.

Abstract

The working principle of CNC Milling machine is the machine rotates and contacts with the workpiece so that erosion and cutting occur. The machining process affects the mechanical properties of the material, so it needs to conduct a study to determine changes in the character of the material due to the machining process. This research was conducted to determine the effect of the number of 2 flutes and 4 flutes on the workpiece surface roughness using PMC-5VT20 CNC Milling machine. Specimens test use 304 material stainless steel that has strength and resistance to the corrosive. The research method was carried out experimentally using 304 stainless steel material which had been done with a finishing process using an endmill cutter with 2 flutes and 4 flutes. The roughness of specimens were tested using surface roughness tester to determain the effect of flute number on the surface roughness. The result of testing shows that the number of flutes affects the roughness of the machining process. The roughness value using 2 flutes is lower than the use of 4 flutes.
