Abstract

The Covid-19 pandemic forced everyone laid off. When the situation recover, do not know. Will he/she return to similar work, do not sure. Continuing stress threats to many people. They need helps, to manage the emotional related impact, to build what new about sense, who he/she might be, to carry on a recent part.

Abstract

Coordinate Measuring Machine (CMM) adalah sebuah alat pengukur multi fungsi dengan kamampuan kecepatan mengukur yang tinggi dan mampu menghasilkan nilai akurasi pengukuran dan efisiensi pengukuran yang tinggi. Pada pengoperasiannya alat ini membutuhkan operator yang memiliki keterampilan khusus dalam menjalankannya.Hal ini dikarenkan dalam pengoperasian Coordinate Measuring Machine (CMM) operator harus membuat program pengukuran terlebih dahulu agar alat dalam digunakan untuk mengukur benda kerja yang diinginkan. Pada pengujiankali ini dilakukan pengoperasian Coordinate Measuring Machine (CMM) serta pembuatan program pengukuran Benda kerja Baja S45-C dengan ukuran diameter dimensi atas 159.76 mm dengan arah ukur CW, dan diameter dimensi bawah 169,76 mm dengan arah ukur CCW, yang mana pada tiap dimensi dilakukan pengukuran berulang sebanyak 5 kali pengukuran dengan tiap sekali pengukuran dilakukan sebanyak 128 titik sampel ukur. Dari hasil pengoperasian yang telah dilakukan didapatkancara mengoperasikan mesin CMM dari awal dihidupkan hinggaselesai pengoperasian. Dan dari hasil pengukuran program yang telah dibuat didapat nilai error benda kerja Baja S45-5 pada diameter atas 159,79 dengan arah probe CW untuk tiap sekali pengukuran dilakukan sebanyak 128 titik ukur sebagai sampel ukur didapatkan nilai error secara berurutan yaitu 0,1933 mm, 0,1936 mm, 0,1933 mm, 0,1940 mm, dan 0,1939 mm. Pada diameter bawah 169,76 dengan arah probe CCW untuk tiap sekali pengukuran dilakukan sebanyak 128 titik ukur sebagai sampel ukur didapatkan nilai error secara berurutan yaitu 0,1606 mm, 0,1608 mm, 0,1606 mm, 0,1612 mm, dan 0,1608 mm.

Abstract

Bengkulu Province from Kaur Regency to Moko-Moko Regency is directly adjacent to the Indian Ocean. So that many Bengkulu residents are fishermen and farmers. Of course, with abundant natural resources, there are some fish and agricultural products that have not been utilized optimally, for example, young fish on Bai Island which are still widely discarded and milled rice bran which is very cheap. On the other hand, there is a very big problem experienced by farmers or breeders in Bengkulu Province, namely the price of fish and poultry feed is very high, thus making fish and poultry farmers unable to survive because of the high cost of feed. To reduce the production cost of making pellets, a research was carried out on optimizing the operation of the pellet molding machine Type MKS-PLT 15 with dimensions of 340 x 150 x 325 mm, the power used was 450 watts and the voltage used was 220 v / 50 Hz. The research carried out looked at the machine operation at 25 percents, 50 percents, 75 percents and 100 percents, from the results of the research that had been carried out, it was found that the 25 percents machine operation cost of 6mm pellet printing was 0.00762 kwh/kg or Rp. 11.021/kg, machine operation 50 percents production cost 0.009901kwh/kg or Rp. 14.3039/kg machine operation 75 percents pellet production cost 0.01235kwh/kg or Rp. 17.842/kg while the machine operation is 100 percents pellet production cost of 0.01084 kwh/kg or Rp. 15.6605/kg. so that from the research carried out, it was found that the operation of the MKS-PLT15 pellet machine, the low production cost, was in machine operation 0-50 percents of the capacity of the pellet machine's ability to operate.
