Abstract

AbstrakDalam uji banding antar laboratorium kalibrasi yang terakreditasi, nilai acuan yang digunakan umumnya dikeluarkan oleh laboratorium metrologi nasional yang bertindak sebagai laboratorium acuan. Tetapi dalam beberapa kasus uji banding, laboratorium metrologi nasional kemungkinan tidak dapat mengeluarkan nilai acuan untuk uji banding karena artefak yang digunakan berada pada level industri, sehingga harus dilakukan cara lain untuk menetapkan nilai acuan. Tulisan ini memaparkan penetapan nilai acuan uji banding berdasarkan konsensus dengan contoh kasus uji banding mikropipet pada nilai nominal 100 μL dan 500 μL menggunakan beberapa pendekatan statistik sebagai estimator. Estimator yang dipilih disesuaikan dengan kondisi data hasil uji banding. Untuk memvalidasi metoda yang digunakan, nilai acuan dari estimator yang dipilih dibandingkan dengan nilai hasil kalibrasi yang dikeluarkan Puslit Metrologi LIPI. Berdasarkan analisis En number diperoleh nilai 0,31 dan 0,21 untuk masing-masing nilai nominal, sehingga dapat disimpulkan bahwa metoda yang digunakan dapat dipertanggungjawabkan..Kata kunci: uji banding, nilai acuan, konsensus, mikropipet.AbstractIn the laboratory comparison between accredited calibration laboratories, generally the reference value used is issued by national metrology laboratory act as reference laboratory. But in some cases, the national metrology laboratory may not provide the reference value for comparisons because of artifacts that are used at the level of the industry, therefore it should be done by another way to determine the reference value. This paper describes the determination of the reference value based on consensus of micropipette laboratory comparison as example cases on the nominal value of 100 μL and 500 μL use several statistical approaches as an estimator. The selected estimator adapted to the conditions of laboratory comparison data. To validate the method used, the reference value of the selected estimator compared with the value of the calibration results issued by Research Center for Metrology LIPI. Based on the analysis of En number, values obtained were 0.31 and 0.21 for each of the nominal value, therefore it can be concluded that the method used is reliableKeywords: laboratory comparison, reference value, consensus, micropipette.

Abstract

AbstrakKegagalan fungsi girder pada lintasan tripper yang sering terjadi disebabkan oleh keretakan pada penopang silang dan tegak, terjadinya defleksi berlebih pada batang utama, dan perubahan posisi pada kedua kolom. Kerusakan strukur diakibatkan oleh ketidaksesuaian pembebanan yang diterima, sehingga memperlemah komponennya dan dapat berakibat runtuhnya struktur girder. Studi dilakukan dengan mengkaji desain yang sudah ada melalui pendefenisian pembebanan, selanjutnya melakukan perhitungan mekanika pada tiga model pembebanan yang berbeda dan pengecekan kelayakan desain dengan metode LRFD berdasarkan SNI 03-1729-2002 dengan validasi menggunakan analisis elemen hingga. Hasil menunjukkan terjadinya ketidaksesuaian pembebanan yang berakibat kerusakan girder, sehingga diperlukan desain alternatif melalui pemilihan profil, perhitungan kelayakan profil dan analisis ulang untuk memastikan kehandalan rancangan. Dari hasil analisis perhitungan dapat disimpulkan bahwa desain alternatif mempunyai kehandalan yang memadai yaitu defleksinya 0,35 mm dibanding desain lama 15,96 mm berdasarkan perhitungan mekanik, sedangkan hasil analisis elemen hingga, defleksi desain baru 1,08 mm dan desain lama 10,37 mm. Tegangan maksimum desain baru adalah aman terhadap material yang digunakan, yaitu SS400 dengan kekuatan sebesar 245 MPa, dimana hasil perhitungan mekanika diperoleh tegangan maksimum desain baru 52,00 MPa, sedangkan tegangan maksimum hasil analisis elemen hingga adalah 56,31 MPa dan tegangan Von Mises 143,39 MPa.Kata kunci : girder, tripper, LFRD, elemen hingga, Standar Nasional Indonesia (SNI).AbstractMalfunction of girder on track tripper that often occurred is caused by cracks in the cross and upright supports, occurrence of excessive deflection on main bar, and a change in position of the both columns. Structural failure is caused by loading discrepancies received, so it is weaken its components and resulted in the collapse of the girder structure. The study was conducted by reviewing existing design through loading analysis, then performing the mechanical calculation on three different loading models and checking the feasibility of the design with LRFD method based on SNI 03-1729-2002 with validation using finite element analysis. Results showed the loading discrepancies resulting in damaged girder, so it is necessary to make design alternatives through the selection of profiles, re-calculation and feasibility analysis of the beam to ensure the reliability of the design. From the calculation analysis, it can be concluded that the alternative design has adequate reliability. Based on mechanical calculations the deflection is 0.35 mm compared to 15.96 mm of the old design, while the result of finite element analysis determine 1.08 mm deflection of the new design and 10.37 mm in old design. The maximum stress of the new design is safe for the material used, ie SS400 with a strength of 245 MPa, wherein mechanical calculation resulted in obtained maximum stress of the new design is 52.00 MPa, while the maximum stress through finite element analysis result is 56.31 MPa and Von Mises stress is 143.39 Mpa.Keywords: girder, tripper, LFRD, finite element, National Indonesian Standard (SNI).
