Abstract

Carbon steel is a primary material in various engineering applications that require cutting accuracy to maintain product quality. Advances in flame cutting technology in the manufacturing industry highlight the importance of understanding proper parameter settings. Incorrect parameter adjustments can lead to inaccuracy, material defects, and increased operational costs. In this study, the Taguchi method combined with ANOVA will be used to optimize dimensional inaccuracy in the CNC flame cutting process on SS400 steel plates. The effects of variations in cutting parameters, including cutting speed, gas pressure, and oxygen pressure, on the dimensional inaccuracy of the cut were identified. The analysis results show that gas pressure is the most influential parameter, with a contribution of 86.31%, followed by cutting speed at 6.06% and oxygen pressure at 2.42%. The optimal parameter combination for minimizing dimensional inaccuracy was found at a cutting speed of 319 mm/min, gas pressure of 4 bar, and oxygen pressure of 6 bar. These findings highlight the importance of adjusting gas pressure to improve cutting accuracy and reduce operational costs and time at PT XYZ.

Abstract

Perkembangan industri yang sangat pesat mengakibatkan suatu perusahaan harus melakukan peningkatan daya saing dan efektivitas proses produksi. Salah satu cara dalam meningkatkan efektivitas proses produksi adalah melakukan penataan fasilitas produksi yang baik dan benar. Permasalahan yang ada pada perusahaan ini adalah pada penataan fasilitas produksi yang hampir tidak berubah banyak dari sejak didirikan dikarenakan alat maupun metode kerja yang tradisional. Dalam pengamatan yang terjadi di lapangan, diketahui bahwa dalam beberapa stasiun kerja terdapat pekerja yang sama. Proses pemindahaan bahan baku dalam proses dil-akukan secara manual oleh para pekerja dan dilakukan berkali-kali oleh pekerja yang sama. Dari permasalahan diatas, maka perlu dilakukan perancangan ulang tata letak fasilitas produksi pada lantai produksi abon sapi. Salah satu proses perancangan tata letak fasilitas produksi yang dapat digunakan yaitu Automated Design Layout Program (ALDEP). Hasil output ALDEP yang sesuai dengan ARC memliki total Total Closeness Rating (TCR) terbesar sebanyak 970 dan diterapkan dalam layout usulan. .Dalam perhitungan perbandingan jarak total antara existing layout dengan layout hasil ALDEP terjadi penurunan sebesar 43 m dari 137 m untuk existing layout menjadi 94 m untuk layout hasil ALDEP.

Abstract

Pekerjaan mengangkat merupakan pekerjaan yang memiliki resiko yang tinggi untuk terkena penyakit akibat kerja. Proses pengangkatan menir beras di PT. XYZ masih mengandalkan tenaga manusia. Oleh sebab itu dengan banyaknya aktivitas manual handling seperti mengangkat dan membawa menir yang dilakukan pekerja setiap harinya, maka kemungkinan besar para pekerja angkat memiliki risiko yang cukup besar pula untuk terkena penyakit akibat kerja dari pekerjaan yang dilakukannya. Tujuan dari penelitian ini antara lain untuk mengetahui apakah aktivitas kerja yang dilakukan di PT. XYZ masih aman dilakukan berdasarkan analisa NIOSH Lifting Equation. Hasil perhitungan LI (Lifting Index) menunjukkan bahwa pekerjaan yang dilakukan pekerja mem-iliki risiko cidera karena nilai LI > 1. Nilai LI yang dihasilkan sebesar 2,35, 2,26, 2,18, 2,11, 2,03. Hasil pengukuran tingkat konsumsi energi pada pekerja adalah 2,2 kkal/menit, 2,2 kkal/menit, 2,7 kkal/menit, 2,8 kkal/menit, 2,5 kkal/menit, berdasarkan hasil tersebut pekerja akan mengalami ke-lelahan karena hasilnya melebihi 1,2 kkal/menit. Kemudian hasil perhitungan gaya tekan ML5/S1 adalah sebesar 7957,07 N, 9857,81 N, 12408,23 N, 12420,13 N dan 12499,31 N, Berdasarkan hasil yang didapatkan gaya tekan ML5/S1 pada pekerja melebihi batas maksimum gaya tekan ML5/S1 normal sebesar 6500 N. Dapat disimpulkan bahwa pekerjaan mengangkut menir beras yang dil-akukan pekerja memiliki risiko cidera, maka perlu adanya perbaikan sistem kerja pada pekerja agar tidak menimbulkan risiko cidera baik jangka pendek maupuk jangka panjang, serta kesehatan para pekerja akan terjamin.
