Abstract
Proses perakitan leaf spring di PT Indospring Tbk membutuhkan ketelitian pengukuran celah kemiringan yang presisi. Saat ini, pengukuran masih menggunakan alat manual taper gauge dan rentan terhadap kesalahan pembacaan visual (human error). Kendala ini memicu pemborosan berupa waktu tunggu dan risiko kerja ulang. Untuk mengatasi hal tersebut, diperlukan perancangan measurement table otomatis berbasis sensor non-kontak guna mendigitalkan perekaman data serta meningkatkan kecepatan dan akurasi inspeksi. Penelitian dimulai dengan identifikasi akar masalah menggunakan metode Fishbone Diagram untuk memetakan kelemahan alat ukur manual. Setelah kebutuhan sistem ditentukan, tahap selanjutnya adalah perancangan konsep 3D measurement table menggunakan perangkat lunak SolidWorks. Proses ini meliputi perhitungan beban, transmisi daya, dan pemilihan komponen mekanis. Desain kemudian dievaluasi melalui simulasi numerikal pembebanan statis untuk memastikan nilai von Mises tidak melebihi batas tegangan luluh materialnya, sehingga struktur aman untuk dioperasikan. Dari hasil analisis dan perhitungan perancangan tersebut, didapatkan spesifikasi komponen measurement table yang presisi menggunakan sensor Keyence CMOS seri IL-300. Untuk sistem penggeraknya, didapat spesifikasi berupa motor induksi Chenta 0,4 kW, transmisi timing belt dan disc coupling Misumi, serta ball screw dan LM Guide THK tipe HSR-15B. Analisis kekuatan desain menunjukkan tegangan maksimum sebesar 6,42 MPa, memenuhi kriteria desain karena jauh berada di bawah batas tegangan luluh material baja (250 MPa). Dengan capaian nilai Factor of Safety minimum sebesar 39, desain measurement table ini terbukti aman dan siap direalisasikan.

The leaf spring assembly process at PT Indospring Tbk requires precise inclination gap measurement. Currently, the measurement still relies on a manual taper gauge and is susceptible to visual reading errors (human error). This constraint triggers waste in the form of waiting time and the risk of rework. To overcome this issue, the design of an automated measurement table based on a non-contact sensor is required to digitize data recording and improve inspection speed and accuracy. The research began with root cause identification using the Fishbone Diagram method to map the weaknesses of the manual measuring tool. Once the system requirements were determined, the next stage was the 3D conceptual design of the measurement table using SolidWorks software. This process includes load calculations, power transmission, and the selection of mechanical components. The design was then evaluated through numerical static load simulation to ensure the von Mises stress value does not exceed the material's yield strength limit, confirming the structure is safe to operate. From the design analysis and calculations, the specifications for the precision measurement table components were obtained, utilizing the Keyence CMOS IL-300 series sensor. For the drive system, the obtained specifications include a 0.4 kW Chenta induction motor, Misumi timing belt and disc coupling transmission, along with a THK ball screw and LM Guide type HSR-15B. The design strength analysis demonstrated a maximum stress of 6.42 MPa, fulfilling the design criteria as it is well below the yield strength limit of the steel material (250 MPa). With a minimum Factor of Safety of 39, this measurement table design is proven to be secure and ready for realization.
