Abstract

Keandalan instrumen pengujian di laboratorium pengujian material memiliki peran penting dalam menjamin akurasi hasil pengukuran dan kualitas data pengujian. Penurunan performa instrumen maupun kegagalan sistem pengukuran dapat menyebabkan penyimpangan hasil pengujian yang berpotensi memengaruhi kualitas produk dan keandalan proses pengendalian mutu. Oleh karena itu, diperlukan pendekatan yang mampu mengevaluasi potensi kegagalan instrumen sekaligus kapabilitas sistem pengukuran secara komprehensif. Penelitian ini bertujuan untuk menganalisis potensi kegagalan instrumen pengujian menggunakan metode Fuzzy Failure Mode and Effects Analysis (Fuzzy FMEA) serta mengevaluasi kapabilitas sistem pengukuran menggunakan Measurement System Analysis (MSA) dengan metode Gage Repeatability and Reproducibility (GRR). Objek penelitian meliputi lima instrumen pengujian, yaitu Thickness Gauge, Roughness Tester, Tensile Tester, Density Tester, dan Chromium Analyzer. Hasil analisis Fuzzy FMEA menunjukkan bahwa Roughness Tester memiliki tingkat potensi kegagalan tertinggi dengan nilai Fuzzy Risk Priority Number (FRPN) sebesar 8.93, diikuti Chromium Analyzer sebesar 8.20, Tensile Tester sebesar 6.40, Thickness Gauge sebesar 5.47, dan Density Tester sebesar 3.33. Validasi menggunakan data historis operasional menunjukkan bahwa instrumen dengan nilai FRPN lebih tinggi cenderung memiliki frekuensi kejadian kegagalan yang lebih besar. Sementara itu, hasil Measurement System Analysis menunjukkan bahwa seluruh instrumen masih memiliki kapabilitas sistem pengukuran yang dapat diterima dengan nilai %GRR di bawah 30%. Berdasarkan hasil integrasi analisis Fuzzy FMEA, data historis, dan MSA/GRR, penelitian ini menghasilkan usulan evaluasi interval kalibrasi yang berbasis kondisi aktual instrumen dibandingkan pendekatan interval kalibrasi periodik tetap. Pendekatan tersebut diharapkan dapat mendukung peningkatan efektivitas pengelolaan kalibrasi serta menjaga keandalan hasil pengujian di laboratorium.

Testing instruments in material testing laboratories play an important role in ensuring the accuracy of measurement results and the reliability of testing data. Instrument failure or degradation in measurement system performance may lead to deviations in test results, which can potentially affect product quality and the reliability of testing processes. Therefore, an analytical approach is required to evaluate the potential failure of testing instruments as well as the capability of their measurement systems. This study aims to analyze the potential failure of laboratory testing instruments using the Fuzzy Failure Mode and Effects Analysis (Fuzzy FMEA) method and to evaluate measurement system capability using Measurement System Analysis (MSA) with the Gage Repeatability and Reproducibility (GRR) approach. The objects of this study include five testing instruments: Thickness Gauge, Roughness Tester, Tensile Tester, Density Tester, and Chromium Analyzer. The results of the Fuzzy FMEA analysis indicate that the Roughness Tester has the highest potential risk with a Fuzzy Risk Priority Number (FRPN) value of 8.93, followed by the Chromium Analyzer with a value of 8.20, Tensile Tester with 6.40, Thickness Gauge with 5.47, and Density Tester with 3.33. Validation using historical operational data shows that instruments with higher FRPN values tend to exhibit higher frequencies of operational failures. The results of the Measurement System Analysis indicate that all instruments still have acceptable measurement system capability, with %GRR values below the 30% threshold. Based on the evaluation results, this study proposes adjustments to the calibration intervals of the instruments by considering the potential failure risk of the instruments as well as the stability of their measurement systems. This approach is expected to assist laboratories in improving the effectiveness of instrument calibration management while maintaining the reliability of testing results.
