Pengembangan Program Gauge R&R Berbasis R untuk Mendukung Analisis Sistem Pengukuran pada Proses Verifikasi Produk Injektor

Abstract

This paper presents the development of an R-based Gauge R&R program to support measurement system analysis in injector product verification. The study is motivated by the reliance on licensed statistical software, limited accessibility, and the need for a more flexible internal workflow. A design-and-development approach was employed, including requirement identification, conceptual design, module and library development, implementation, and initial validation through comparative analysis. The developed program supports crossed and nested study designs, normalized data processing, ANOVA, variance component estimation, study variation analysis, and interpretative graphical outputs. Validation results indicate that the program produces consistent and reliable analytical outputs compared to conventional tools. The findings demonstrate that a modular R-based application can effectively support measurement system analysis, improve analytical efficiency, and enhance decision-making reliability in verification processes.
