<![CDATA[Processing Total Station measurement data in fabrication work requires an efficient, consistent, and accurate workflow, particularly when comparing actual positions with design positions. Manual processing involves several stages, including coordinate processing, deviation calculation, and visualization in AutoCAD, which may increase processing time and the potential for operator errors. This study aims to develop and implement the ECC.LSP AutoLISP program in AutoCAD to automate Total Station data processing and evaluate its effectiveness compared with the manual method. The study was conducted at PT Rotary Engineering Indonesia using 12 sample points. ECC.LSP was developed to read design and actual point coordinates, calculate coordinate deviations, determine displacement direction, and generate visualizations in the form of arrows and deviation values in AutoCAD. The evaluation was based on processing time, accuracy, consistency, and potential errors. The results showed that processing time decreased from 25 minutes using the manual method to 7 minutes using AutoLISP, representing a 72% time efficiency. Both methods demonstrated high accuracy, while the AutoLISP method provided higher consistency than the manual method. The potential for errors was also lower when using AutoLISP. These findings indicate that ECC.LSP can improve the efficiency and consistency of Total Station data processing without reducing the accuracy of the results in the conducted evaluation.]]>
