Abstract

PT ABC as an automotive component manufacturing company faces the problem of high Downtime in CNC machines, especially the Hyundai Wia F500D Vertical Machining Center, which has an impact on decreased productivity and increased production costs. This study aims to identify the root cause of the failure of the cutting system in the machine and provide recommendations for appropriate repairs. The method used is Root Cause Analysis (RCA) with the Fishbone Diagram approach and 5 Why's analysis based on historical company data, field observations, interviews with related parties, and technical documentation. The results of the study show that the dominant root cause of cutting system failure is damage to the drawbar disspring which reduces the grip strength of the tool so that it triggers the condition of the tool oblique, spindle overload, and active system alarm. Other causative factors include production methods with aggressive cutting parameters, operator errors in tool installation and maintenance, machine age that has been more than 12 years with almost non-stop operation, and a less ergonomic working environment. These conditions have an impact on increasing the frequency of repairs, maintenance costs, decreased production output, and high potential product defects. The conclusion of this study is the need for corrective actions in the form of replacing drawbar dissprings and repairing spindle components, as well as preventive measures through scheduled maintenance, optimization of production methods, improvement of operator competence, and improvement of the layout of the work area.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan efisiensi, kenyamanan, dan keselamatan kerja pada proses produksi opak ketan di UMKM Opak Ketan Cibuaya yang berlokasi di Desa Pejaten, Kecamatan Cibuaya, Kabupaten Karawang. Permasalahan utama yang dihadapi mitra meliputi rendahnya efisiensi produksi, postur kerja yang tidak ergonomis, serta belum adanya standar operasional yang memadai, sehingga berdampak pada keluhan muskuloskeletal, ketidakkonsistenan ukuran produk, dan penurunan produktivitas. Metode pelaksanaan PkM menggunakan pendekatan partisipatif dan kolaboratif dengan melibatkan mitra secara aktif sejak tahap identifikasi masalah, perancangan solusi, implementasi, hingga evaluasi. Intervensi yang dilakukan meliputi perancangan dan penerapan meja kerja ergonomis, penyediaan alat bantu poka-yoke berupa cetakan opak untuk menyeragamkan ukuran produk, serta sosialisasi dan pendampingan terkait efisiensi dan keselamatan kerja. Hasil kegiatan menunjukkan adanya peningkatan kenyamanan kerja, penghematan waktu proses produksi, serta meningkatnya keseragaman ukuran opak yang dihasilkan. Selain itu, evaluasi pascapelaksanaan mengindikasikan peningkatan produktivitas, penurunan variasi produk, dan meningkatnya kesadaran pekerja terhadap pentingnya keselamatan dan kesehatan kerja. Secara keseluruhan, kegiatan PkM ini memberikan dampak positif bagi masyarakat sasaran dengan menunjukkan bahwa penerapan prinsip ergonomi dan poka-yoke yang sederhana, aplikatif, dan berbiaya rendah dapat menjadi solusi efektif dan berkelanjutan dalam meningkatkan kinerja produksi sekaligus kesejahteraan pekerja UMKM.
