Abstract

P PT. AHM merupakan salah satu perusahaan yang bergerak di bidang industri otomotif yang memproduksi sepeda motor. Dalam menghasilkan produknya, PT. AHM selalu berusaha mengutamakan mutu agar konsumen merasa puas. Disamping itu juga karena banyaknya pesaing-pesaing ba' dalam industri sepeda motor, seperti masuknya motor produksi Cina, Korea. Seksi Assembling merupakan salah satu seksi yang ada di PT. AHM. Seksi ini yang melakukan proses perakitan sepeda motor. Jenis cacat yang terjadi pada Seksi Assembling sangat bervariasi. Tetapi untuk cacat tertentu, yaitu rear fender miring, persentase cacatnya sangat tinggi dibandingkan jenis cacat yang lain Sampai saat ini, perusahaan telah melakukan pemeriksaan mutu produknya dan telah dilakukan usaha-usaha pengendalian mutu untuk menurunkan persentase cacat Karena target produksi merupakan prioritas perusahaan disamping mutu, maka pengendalian mutu produk hanya difinjau secara unium. Old] karena itu, perlu adanya pengendalian mutu statistikal terhadap proses perakitan sehingga dapat menurunkan persentase cacat dominan. Untuk memecahkan masalah tersebut, diperlukan pemahaman terlebih dahulu rnengeriai proses assembling, identifikasi faktor penyebab jenis cacat dominan. Selanjutnya dilakukan pengambilan data jumlah produksi harian yang mengalami cacat selama 2 bulan (Maret dan April 2001), lalu dilakukan pembuatan peta kontroi p untuk periode Maret-April 2001 untuk mengetahui apakah proses dalam keadaan terkendali atau tidak. Hasil perhitungan peta koritrol p menunjukkan proses assembling dalam keadaan tidak terkendali, yaitu 12 titik dimana terdapat 5 titik diluar batas kendali bawah dan 7 titik berada di luar batas kendali alas. Kemudian dilakukan revisi terhadap peta p dengan membuang titik-titik yang di luar kendali. Selanjutnya dilakukan pemilihan jenis cacat yang paling berpengaruh pada proses assembling selama rvia-ret-April 2001 dengan Diagram Pareto. Penyelesaian masalah diprioritaskan pada jenis cacat dorninan, yaitu rear fender miring, steering handle oblak, steering handle seret, screw cover body (L) tidak terpasang, kemudian dicari faktor penyebab keempat jenis cacat tersebut yang terdiri dan faktor manusia, alat, metode dan bahan, lalu digambarkan dengan diagram sebab-akibat. Ter dapat 5 faktor penyebab rear fender miring, 3 faktor penyebab steering handle oblak, 3 faktor penyebab steering handle seret dan 2 faktor penyebab screw cover body (L) tidak terpasang ; kemudian berdasarkan tiap-nap faktor tersebut diberikan usulan perbaikan dengan prinsip 5W 1H.

P PT. AHM is a company engaged in the automotive industry that produces motorcycles. In producing its products, PT. AHM always strives to prioritize quality so that consumers feel satisfied. In addition, it is also due to the many competitors in the motorcycle industry, such as the entry of Chinese and Korean motorcycles. The Assembling Section is one of the sections in PT. AHM. This section carries out the motorcycle assembly process. The types of defects that occur in the Assembling Section vary greatly. However, for certain defects, namely slanted rear fenders, the percentage of defects is very high compared to other types of defects. Until now, the company has conducted product quality inspections and quality control efforts have been carried out to reduce the percentage of defects. Because production targets are the company's priority besides quality, product quality control is only reviewed in general. Old] Therefore, it is necessary to have statistical quality control of the assembly process so that it can reduce the percentage of dominant defects. To solve this problem, it is necessary to first understand the engineering of the assembly process, identify the factors causing the dominant types of defects. Next, data collection was conducted on the number of daily production defects for 2 months (March and April 2001), then a p control map was made for the period March-April 2001 to determine whether the process was in a controlled state or not. The results of the p control map calculation showed that the assembly process was in an uncontrolled state, namely 12 points where there were 5 points outside the lower control limit and 7 points outside the lower control limit. Then a revision was made to the p map by removing the points that were out of control. Next, the type of defect that had the most influence on the assembly process during the rvia-ret-April 2001 was selected using a Pareto Diagram. Problem solving was prioritized on the dominant type of defect, namely tilted rear fender, loose steering handle, dragging steering handle, screw cover body (L) not installed, then the causal factors of the four types of defects were sought, consisting of human factors, tools, methods and materials, then described with a cause-effect diagram. There are 5 factors that cause the rear fender to tilt, 3 factors that cause the steering handle to wobble, 3 factors that cause the steering handle to drag and 2 factors that cause the body cover screw (L) not to be installed; then based on each of these factors, repair suggestions are given with the 5W 1H principle.
