Abstract

Tujuan utama dari pengendalian kualitas yaitu untuk mempertahankan dan meningkatkan kualitas produksi yang dihasilkan oleh suatu perusahaan. Salah satu metode pengendalian kualitas yang sering digunakan adalah diagram kontrol. Dalam penelitian ini diterapkan diagram kontrol Cumulative Sum (CUSUM) dan Decision On Belief (DOB) dimana keduanya merupakan pengontrol kualitas dari data univariat. Studi kasus dilakukan di PT. Pacific Angkasa Abadi dengan data yang dipakai yaitu jumlah produksi pipa besi yang cacat periode Juli hingga September 2018. Penerapan diagram kontrol CUSUM dan DOB menunjukkan bahwa produksi pipa besi belum terkendali secara statistik. Dari hasil analisis, dapat disimpulkan bahwa diagram kontrol DOB menghasilkan 10% lebih sensitif bila dibandingkan dengan diagram kontrol CUSUM berdasarkan jumlah data yang out of control.

The main purpose of quality control is to maintain and improve the quality of production produced by a company. One quality control method that is often used is a control diagram. In this study Cumulative Sum (CUSUM) and Decision On Belief (DOB) control diagrams are applied, both of which are quality controllers of univariate data. Case studies conducted at PT. Pacific Angkasa Abadi with the data used is the number of defective iron pipe production from July to September 2018. The application of CUSUM and DOB control diagrams shows that iron pipe production has not been statistically controlled. From the results of the analysis, it can be concluded that the DOB control diagram produces 10% more sensitive when compared to the CUSUM control diagram based on the amount of data out of control.
