Abstract

PT. XYZ merupakan salah satu perusahaan manufaktur yang salah satu produk unggulannya adalah produk kabel NFA2X. Pada perkembangannya permintaan akan produk tersebut terus meningkat. Selain itu permintaan pada kualitas produk kabel NFA2X tersebut juga meningkat. Tetapi dari data produksi hanya dicapai 80% dari target produksi selama Tahun 2021. Hal ini salah satunya disebabkan oleh tingginya downtime dari mesin extruder yang digunakan pada proses produksi. Tujuan dari penelitian ini melakukan pengukuran kinerja mesin extruder pada produk kabel NFA2X dengan menghitung nilai Overall Equipment Effectiveness (OEE) dari mesin extruder untuk mengetahui kinerja mesin selama Tahun 2021 sudah maksimal tersebut sehingga didapatkan data kinerja mesin extruder selama Tahun 2021. Dari data Overall Equipment Effectiveness (OEE) yang didapatkan selanjutnya dilakukan analisis kinerja mesin extruder menggunakan cause effect diagram untuk mengetahui penyebab rendahnya kinerja mesin extruder dan memberikan usulan perbaikan untuk meningkatkan kinerja mesin extruder. Dari hasil perhitungan didapatkan bahwa nilai Availability adalah 94 %, Rate of Quality adalah 100 %, Performance Efficiency adalah 80% dan Nilai Overall Equipment Effectiveness (OEE) adalah 83% dimana nilai tersebut masih di bawah nilai standar dunia.

Abstract

PT Agung Pelita Industrindo is a company engaged in the shoe industry that specializes in producing accessories or shoe components for various types of shoes. One of the products produced is the Foxing component product, which is a component produced for the NIKE Air Max Plus type of shoe. Based on the results of observations, it is known that the production process for Foxing component products still has product defects and The purpose of this research is to control the quality of the product of the foxing component at PT. Agung Pelita and to get information the most dominant types of defects in the Foxing production process and the factors causing the occurrence of defective products using the Statistical Process Control (SPC) method and providing suggestions for improvements to reduce the number of defective products. From the results of the analysis obtained six types of defects produced in the Foxing component production process, the more dominant type of defect is waste defects, namely defects that occur due to unwanted small prints on Foxing component materials, so that the proposed improvements that can be made by PT Agung Pelita Industrindo to reduce the number of waste defects in the production process of Foxing's component products is to hold outreach to operators to improve understanding of SOPs related to mold cleaning.

Abstract

PT RAA is one of company that moves in terms of pharmaceutical industry. In the process of checking the quality of pharmaceutical products involving one of the instrumentation namely HPLC (High Performance Liquid Chromatography). The data used in the research is secondary data obtained from the instrument logsheet hplc 2019 2010 than years up to. The method used to determine the critical component is the ABC Classification Method. he critical components of the HPLC instrumentation tool are D2 Lamp L-6585-02 with MTTF value of 277 days, Grating component, Sample Loop Assy with MTTF value of 305 days, and Plunger and Peek Neddle Seal components with MTTF value of 342 days. Calculation of the value of function damage to critical components used the calculation of the selected distribution method, namely Weibull distribution. Optimal ordering for D2 Lamp component L-6585-02 is 2 units / year with 1 unit ordering point, Grating component, Sample Loop Assy is 3 units / year with 1 unit ordering point, and Plunger and Peek Neddle Seal components are 3 units / year with a ordering point of 1 unit.

Abstract

XYZ Inc. is one of manufacturing companies that produce eco friendly polymer/resin. Five production machines were used to do some production process such as mixing and extracting. Production machine number three often suffered trouble that caused production stop. the purpose of this research is to calculate performace of production machine number three using Overall Equipment Effectiveness (OEE) and analyze the elements that caused failure of production machine number three using Failure Mode and Effect Analysis (FMEA). The data that used in this research was January to December 2019. The result showed that average OEE value is 70,49%, the highest RPN value is 448 on heating process and critical component of production machine number three was heater.
