Evaluasi Pengujian Mekanik Ban Sepeda Motor Berbasis SNI dan PDCA di Laboratorium Pemerintah

Abstract

Mechanical testing of tire products is a crucial component of quality control systems, essential for ensuring the safety of vehicle users. This study examines the implementation of mechanical testing processes for tires, based on quality control standards, within the Mechanics Laboratory at the Directorate of Standardization and Quality Control, Ministry of Trade of the Republic of Indonesia. The methodology employed includes direct observation, documentation, literature review, and interviews conducted during an internship from January 12 to February 12, 2026. The test subject was an 80/80-14 43S motorcycle tire, evaluated in accordance with the SNI 0101:2012 standard, using the Plan-Do-Check-Act (PDCA) cycle as a quality control framework. The test results indicate that all six parameters met the requirements of SNI 0101:2012: a total tire width of 77 mm (within the 77–88 mm range), a total diameter of 488 mm (within the 480–492 mm range), an average Tread Wear Indicator height of 1.0 mm (minimum 0.8 mm), a penetration energy of at least 347.22 J (minimum 347 kgf.cm), and diameter changes of 0.2% following the load endurance test and 0.6% following the high-speed test (both well below the maximum limit of ±3.5%). The application of the PDCA cycle fostered a structured workflow, encompassing everything from initial planning to continuous improvement. In conclusion, the Mechanics Laboratory’s operational system grounded in SNI and SNI ISO/IEC 17025 standards and the PDCA cycle ensures the reliability and validity of tire test results. However, the penetration energy parameter, which showed a narrow margin, warrants closer attention to maintain consistent production quality.
