Abstract

ABSTRAK Seperti yang tertuang dalam SNI 03-1729-2002 dalam persyaratan perencanaan struktur, tujuan perencanaan struktur adalah untuk menghasilkan suatu struktur yang stabil, cukup kuat, mampu layan, awet dan memenuhi tujuan-tujuan lainnya sepertti ekonomi dan kemudahan pelaksanaan. Ada dua metode yang dapat digunakan untuk analisa konstruksi yaitu metode elastisitas dan metode plastisitas. Namun penyelesaian dengan metode plastis dianggap lebih menguntungkan karena dapat meramalkan beban runtuh sehingga pendimensian pada struktur lebih ekonomis. Pada perencanaan digunakan metode mekanisme dan elemen hingga untuk menganalisa faktor beban runtuh dari portal yang menggunakan profil IWF 300 x 300 pada balok dan profil IWF 400 x 300 pada kolom. Dari analisa yang dilakukan struktur portal melalui analisa plastis dengan perhitungan metode elemen hingga faktor beban runtuh sebesar sedangkan dengan menggunakan metode mekanisme didapat beban runtuh sebesar 2.431 . Kata Kunci : Plastisitas, perencanaan struktur, beban runtuh, portal baja,

Abstract

Public construction materials laboratories play a vital role in safeguarding infrastructure quality and public safety. Although ISO/IEC 17025:2017 is widely adopted as a quality management system, its actual influence on strategic performance in government laboratories is not well understood. This study evaluates the implementation of ISO/IEC 17025:2017 at a provincial government testing laboratory in North Sumatra, Indonesia, by integrating it with the Balanced Scorecard (BSC) framework. A mixed-methods approach was used involving 60 participants—30 internal personnel and 30 external users—through surveys, interviews, and direct observation. The BSC evaluation produced a performance score of 77.35%, categorized as satisfactory, with the strongest contribution from customer and financial perspectives. This study introduces an integrated evaluation framework tailored to public laboratories, bridging quality compliance with strategic governance. The results highlight the importance of aligning technical quality with institutional accountability, offering a practical pathway for improving performance and public trust in government testing services.

Abstract

Construction materials testing laboratories play a strategic role in ensuring the quality of infrastructure development. The implementation of ISO/IEC 17025:2017 as a quality management system is a crucial instrument to guarantee technical competence and the validity of test results. However, the effectiveness of this standard's implementation in achieving strategic performance in government laboratories remains underexplored. This study was conducted at the Construction Materials Laboratory Unit (UPTD) of the Department of Public Works and Spatial Planning (PUPR), North Sumatra Province, with the objective of evaluating laboratory performance through the integration of ISO/IEC 17025:2017 and the Balanced Scorecard (BSC) approach. A mixed methods design was employed with purposive sampling involving 60 respondents—30 internal personnel and 30 external service users. Data were collected through questionnaires, structured interviews, and document-based observations. Multiple linear regression analysis of 16 ISO-related variables identified three significant predictors of performance: Traceability Investment (β=0.044), Method Validity (β=0.023), and Management Transparency (β=0.030). Four additional variables with strong beta coefficients derived from interviews and observations were also considered in defining strategic objectives. The BSC-based performance evaluation yielded an overall score of 77.35% ("fairly good"), with the highest contributions from the customer and financial perspectives. The resulting evaluation model offers a practical reference for strengthening accountable and sustainable governance in public laboratories. Future research is recommended to apply this model to government laboratories of varying scale, complexity, and organizational structure in order to assess its external validity and contextual adaptability.
