Abstract

Abstrak
Diseminasi nilai kalibrasi resistor standar kepada standar kerja di Puslit Metrologi - LIPI telah dilakukan. Hal ini bertujuan untuk mendapatkan hasil kalibrasi dan estimasi ketidakpastiannya yang valid dan tertelusur ke SI pada standar kerja. Desiminasi dilakukan dengan cara mengimplenmentasikan nilai kalibrasi resistor standar 1 kΩ ke resistor acuan dan kemudian ke standar kerja. Nilai yang telah diturunkan kepada standar kerja, reference multimeter, telah dibandingkan dengan nilai pengukuran yang dilakukan oleh KRISS (Korea Research Institute of Standards and Science) melalui kriteria derajat ekuivalensi. Error number berdasarkan kriteria derajat ekuivalensi antara Metrologi - LIPI dan KRISS pada resistor-resistor 100Ω, 10Ω, dan 1Ω masing-masing adalah sebesar 0,51, 0,73, dan 0,87. Berdasarkan error number tersebut, hasil pengukuran Metrologi - LIPI memiliki kesesuaian nilai ukur dengan hasil ukur KRISS. Lebih daripada itu, hal tersebut telah memvalidasi hasil kalibrasi dan estimasi ketidakpastian dari resistor acuan dan standar kerja di Puslit Metrologi - LIPI.
Kata kunci: nilai kalibrasi, resistor standar, standar kerja, kriteria derajat kebebasan, validasi.

Abstract
Dissemination of calibration value of standard resistor to working standard in Research Center for Metrology LIPI has been done. It aims to get the calibration result and the uncertainty estimation that are valid and traceable to SI on the working standard. The desimination was performed by implementing calibration value of 1 kΩ standard resistor to reference resistor and then to working standard. The value that had been disseminated to working standard, reference multimeter, had been compared to the measurement value made by KRISS (Korea Research Institute of Standards and Science) through a degree of equivalence criteria. The error numbers based on the degree of equivalence criteria between Metrology-LIPI and KRISS for the resistors measurement of 100Ω, 10Ω, and 1Ω were 0.51, 0.73, and 0.87 respectively. Based on those error numbers, Metrology-LIPI measurement results had the measuring value agreement with KRISS measurement results. Moreover, Its had validated calibration result and the uncertainty estimation of reference resistor and working standard in Metrology LIPI
Keywords: calibration value, standard resistor, working standard, degree of equivalence criteria, validation.
