Abstract

This study is concerned with maintenance on a heavy equipment excavator 390D series HE4019, one of the main tools used to support the process of nickel production. Major constraint in using this tool is an insufficiently planned maintenance such that the tool affected operational and production process of nickel. Failure mode and effect analysis (FMEA) method is used to identify the risks of failure of critical components on the performance of the unit. Based on risk priority number (RPN), three critical components are found as leading causes of unit downtime. These are stick cylinder (RPN 288), fuel filter (RPN 280) and oil pan (RPN 240), respectively. Mean time between failure (MTBF) scores of stick cylinder, fuel filter and oil pan are 1,288.91 hours, 334.04 hours and 1,455.77 hours, respectively. Each of making rod of the cylinder covered, periodically flushing the fuel tank and taking on a warning sign on the couplers and coating the gasket with an additional layer during installation, in the meantime, are proposed as preventive maintenance for each the three critical components.

Abstract

AbstractThe study aimed to minimize defective products to improve the production process quality of PT BI by identifying the most types of defects, calculating Defect per Million Opportunities (DPMO) value, suggesting the quality improvement of the Semi Refined Carrageenan (SRC) production process, and calculating Cost of Poor Quality (COPQ) value. The methods used in this research were Six Sigma and the COPQ. The priority improvement based on the Pareto chart was moisture defects with the percentage of damage of 36.9%. The Sigma level of the production process of PT BI was 3.42 with a defect rate of 27,429 DPMO. The analysis on the cause and effect diagram showed that factors affected the occurrence of defective products were error in reading on moisture content, diverse raw material, the wrong method of mixing raw materials prior to production process, and the lack of inspectors of production process. The most influential-dominant factor was the obsolete machine which causes error in reading on moisture content. The company can take preventive and corrective actions to suppress defective products and improve product quality. Based on the calculation of the COPQ, the costs that must be incurred by the company due to defective products was IDR 1,007,690,694.Keywords: Cost of Poor Quality (COPQ), quality control, seaweed, Six Sigma AbstrakPenelitian ini bertujuan untuk meminimalkan jumlah produk cacat sehingga meningkatkan kualitas proses produksi PT BI dengan mengidentifikasi jenis cacat terbanyak, menghitung nilai Defect per Million Opportunities (DPMO), menyarankan perbaikan kualitas proses produksi Semi Refined Carragenan (SRC) serta menghitung nilai Cost of Poor Quality (COPQ).

Abstract

AbstractQuality is a crucial factor of an industry. PT XYZ is an exporter and distributor company of seaweed in Makassar city. It exports various varieties of seaweed, one of them is Eucheuma cottonii. Quality must be maintained to preserve and increase company image or reputation and consumer satisfaction. The study aims to improve quality of seaweed through quality control by using Statistical Quality Control (SQC) method. Receiving data of Eucheuma cottonii seaweed obtained from 30 sample groups, each group contains three different samples. Analysis on the process capability then was carried out so that the obtained score of process capability ratio was 0.35<1 and the process capability index score was -0.12<0. It can be concluded that the receiving process of seaweed in this company was incapable and need improvement to increase receiving process capability of seaweed. Several factors caused this incapable process were the unskilled human resources on seaweed handling in material receiving process and during distribution process from the farmer, the limitation of reliable measuring instruments, and the lack of constructive partnership between farmers, suppliers, and industry. Hence, this study suggested to improve skills of the employee, supplier, and farmer regarding seaweed cultivation and handling, to provide more reliable measuring instruments, and to develop constructive partnership development among farmer, supplier, and industry as an improvement of seaweed quality on receiving process.Keywords: Statistical Quality Control, quality control, Euchema cottonii, seaweed AbstrakKualitas merupakan faktor penting dalam suatu industri. PT XYZ merupakan perusahaan eksportir dan distributor rumput laut di Kota Makassar yang mengekspor berbagai macam jenis rumput laut, salah satunya jenis Eucheuma cottonii. Kualitas produk perlu dijaga untuk mempertahankan dan meningkatkan citra perusahaan dan kepuasan konsumen. Kajian ini bertujuan meningkatkan kualitas rumput laut melalui pengendalian kualitas dengan metode Statistical Quality Control. Data penerimaan rumput laut jenis Eucheuma cottonii diperoleh sebanyak 30 kelompok sampel dan tiap kelompok terdapat tiga sampel yang berbeda. Selanjutnya dilakukan analisis kemampuan proses agar didapatkan nilai untuk rasio kemampuan proses adalah 0,35<1, dan untuk indeks kemampuan proses adalah -0,12<0. Dari hasil perhitungan dapat disimpulkan bahwa proses penerimaan rumput laut di perusahaan ini tidak capable, sehingga perlu dilakukan perbaikan untuk meningkatkan kapabilitas proses penerimaan rumput laut. Beberapa faktor yang menyebabkan proses not capable yaitu keterbatasan pengetahuan pada sumber daya manusia terkait dengan penanganan rumput laut pada proses penerimaan material dan selama proses distribusi dari petani, keterbatasan alat ukur yang reliable, lemahnya kemitraan konstruktif antara petani, pemasok, dan industri. Kualitas rumput laut pada proses penerimaan dapat ditingkatkan dengan melakukan peningkatan pengetahuan pada pekerja, pemasok, dan petani mengenai budidaya dan penanganan rumput laut, penyediaan alat ukur yang andal, serta pengembangan kemitraan yang konstruktif antara petani, pemasok, dan industri.Kata kunci: Euchema cottonii, quality control, rumput laut, Statistical Quality Control
