This paper discusses part of Tribotronic system on Pin-On-Disc (POD) Tribometer focusing on friction measurement using load cell. The analysis conducted using MATLAB software to measure Coefficient of Friction (CoF) of 2 sample types in order to prove the validity of the measurement. The 2 samples are lubricant (Shell Helix Fully synthetic oil) and lubricant (Shell Helix Fully synthetic oil) with additive. It is revealed that the measurement of the lubricant with additive shows better CoF (0.006) than lubricant without additive, CoF of 0.02.
