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

Marking machining processes using lasers have developed in the industrial world. Having high precision and good final quality is one of the advantages of this laser machine. There is a thermal effect generated in the process, so we must understand the impact of the power applied to the material. Carry out the laser marking process with the engraving method on a stainless steel plate material which is given a variation of strength to observe the difference in the final result of a marking. Make as many as 3 pcs of products for each variation of power parameters. The product that has been produced will also be observed for surface roughness on the marking, which aims to find out how deep the food is from the marking. Observation of the surface roughness of the marking on the product using the Surface Roughness Tester 3 times for each product. The results of the data that have been taken will only be observed and entered into the marking results into the roughness class according to ISO or DIN 4763:1981. The marking process uses power variations of 20%, 40%, 60%, 80% and 100%. The results of the marking with the lowest power of 20% produce markings with a roughness value of 0.029µm – 0.110µm and enter into class N3 while the results of marking with the greatest power of 100% obtain a roughness value of 18.210µm – 19.876µm which is included in the roughness class N10. Based on the data obtained in the engraving process with different power variations, it can be interpreted that the higher the power supplied, the higher the roughness value

Abstract

Penelitian ini bertujuan untuk mengetahui kekasaran permukaan material baja dengan jenis ST 37 akibat variasi proses pengasahan batu gerinda. Sebagai proses finishing pada produk manufaktur, maka proses menggerinda datar perlu diketahui parameter asahan batu yang tepat. Penggunaan ST 37 sendiri menjadi pertimbangan karena kebutuhan material benda kerja untuk pendidikan di laboratorium manufaktur. Metode penelitian pendekatan eksperimen pada 3 spesimen dengan 3 variasi parameter pengasahan batu gerinda. Pengambilan data enggunakan konsep duplo untuk memperoleh data lebih dari satu. Setiap data sampel mempunyai 6 pengukuran. Hasil yang diperoleh yaitu, variasi 1 mendapat nilai kekasaran permukaan N6 dengan rata-rata kekasaran 0,839 ?m.Variasi 2 memperoleh nilai kekasaran permukaan N6 dengan nilai rata-rata kekasaran 0,650 ?m. Variasi 3 didapatkan nilai kekasaran permukaan N8 dengan nilai rata-rata 2,685 ?m. Sehingga, dapat disimpulkan bahwa pengasahan batu gerinda berpengaruh terhadap perubahan nilai kekasaran permukaan, baik variasi 1 maupun 2.
