Abstract

Quality is a characteristic or value inherent in a product and plays an important role in maintaining a company’s competitiveness. An automotive spare parts company producing tool holders, with part 3060HD as its flagship product, experienced quality problems in the form of fluctuating and unstable defect levels during the period from January to October 2024. This condition potentially causes financial losses because the defect rate has exceeded the tolerance limit set by the company. Therefore, this study aims to determine the level of defects that occur, analyze the factors causing defects at each stage of the production process, and formulate improvement efforts to reduce the number of defective products. The method used in this study is Statistical Quality Control (SQC). Based on production data from January to October 2024 with a total production of 3,623,736 units, the number of defective products for part 3060HD was 47,572 units, consisting of 27 types of defects and 1 mixed defect type. The highest defect was caused by synchronization tool change problems, with a total of 6,365 defective units. The analysis results indicate that defects are influenced by man, method, machine, material, measurement, and environment factors. The results of this study are expected to serve as a reference for the company in implementing continuous improvement to enhance product quality and minimize defect rates.

Abstract

PT Yili Indonesia Dairy adalah perusahaan Fast Moving Consumer Goods (FMCG) dengan produk utama es krim Joyday. Pada proses produksinya, khususnya pada pembuatan bahan baku coklat di area mixer, beberapa aktivitas masih dilakukan secara manual, seperti mengambil material, mengangkat material, dan mendorong tangki. Berdasarkan wawancara, pekerja sering mengalami keluhan Musculoskeletal Disorders (MSDs) saat melakukan aktivitas tersebut. Untuk itu, diperlukan rekomendasi perbaikan postur kerja guna menurunkan risiko MSDs. Penelitian ini menggunakan metode Quick Exposure Check (QEC) dan Rapid Entire Body Assessment (REBA) untuk menilai tingkat risiko ergonomi. Hasilnya menunjukkan bahwa aktivitas mengambil dan mengangkat material berada pada kategori risiko tinggi. Aktivitas mengangkat material memperoleh QEC 74% dan REBA 8 (risiko tinggi) sehingga direkomendasikan penggunaan forklift yang menurunkan skor REBA menjadi 2 (risiko rendah). Aktivitas lainnya memiliki QEC 93% dan REBA 12 (risiko sangat tinggi) sehingga disarankan penggunaan hydraulic lift table yang menurunkan skor REBA menjadi 4 (risiko sedang)

Abstract

PT XYY is a company that focuses on activities in the field of Fast Mouving Consumer Goods (FMGC), namely ice cream products with the JY brand. The problem that is often encountered at PT XYY is the frequent stopping of the production process due to downtime. The machine that often experiences downtime is the corn egroll machine which is one of the machines used as a stage in the ice cream making process. One solution to overcome this problem is to approach total productive maintenance (TPM) as a whole which is measured using the Overall Equipment Effectiveness (OEE) method.sas a critical measuring tool for assessing productivity and operational efficiency.  and find out the dominant root cause of OEE problems with fishbone diagram. The calculation results show that the OEE value on the corn egroll machine in November is 66.03%, this value is far below the international standard of 85%. The decrease in the OEE value is mainly due to the low operation time which is influenced by the fairly high machine downtime. This is also reflected in the machine availability value which is only 81.74%, which indicates an imbalance between operating time and time that should be used for production.
