Abstract
Flexible Manufacturing System (FMS) is one of the modern production systems that support the implementation of Industry 4.0. An educational institution plans to build an FMS model for learning the modern production systems. The FMS is a manufacturing system consisting of a set of automatic workstations connected to a material handling system where all activities are controlled by a computer system. The material handling system consists of a material storage system and a transportation system, one example of a transportation system is the stacker crane. In this research, the stacker crane model has been built which consists of three main components, which are the bottom frame, the mast, and the carriage. This component is equipped with stepper motors, leadscrews that are controlled by the micro controller and an application on Android. The stacker crane model is tested to retrieve and deliver the stereofoam material model to the destination which is controlled by the user using an application on Android. The characteristics of the stacker crane model can move the workpiece with a maximum error of 2 mm in the positive x-axis direction, 2 mm in the negative x-axis movement, up to 2 mm positive y-axis, downward at negative y-axis direction 2 mm.

Summary
Setelah perancangan model stacker crane selesai dilakukan, maka pada tahap ini akan dilakukan pengujian. Pengujian Bottom Frame Pengujian ini akan dilakukan untuk mengetahui apakah Bottom frame bergerak sesuai perintah yang diberikan melalui aplikasi Serial Bluetooth Terminal android. Sebelumnya telah dilakukan proses kalibrasi untuk memastikan bahwa perintah melalui androids dapat menggerakkan bottom frame ke tempat yang dituju. Kesalahan posisi selama tujuh kali pengujian yang dilakukan untuk memindahkan dari sebuah posisi ke posisi lain ditunjukkan pada Tabel 1. Pengujian Mast Mast yang digunakan pada penelitian ini akan diuji apakah mast bergerak dalam arah ke atas maupun ke bawah pada sumbu-y sesuai perintah yang diberikan melalui android dan apakah dapat berhenti tepat pada lantai tertentu. Susunan konstruksi pengujian disajikan dengan padangan depan stacker crane yang terdiri dari tiga tingkat, ditunjukkan pada Gambar 13. Pengujian dilakukan sebanyak tujuh kali dan eror selama pengujian ditunjukkan pada Tabel 2.
