Abstract

Permasalahan sampah plastik di Indonesia memerlukan teknologi pengolahan yang sesuai untuk skala komunal, khususnya pada tahap reduksi ukuran sebelum proses daur ulang lanjutan. Penelitian ini bertujuan merancang mesin shredder botol plastik dual poros berbasis Internet of Things (IoT), menentukan spesifikasi teknis sistem mekanik, mengevaluasi kekuatan komponen kritis, serta merancang sistem elektrikal dan kontrol. Metode penelitian meliputi perancangan konseptual, pemodelan 3D, perhitungan elemen mesin, penyusunan Bill of Materials, simulasi Finite Element Analysis menggunakan Autodesk Inventor, analisis modal rangka, serta perancangan arsitektur elektrikal dan IoT. Hasil penelitian menghasilkan sistem transmisi pulley–V-belt tiga tahap berasio total 23,52 untuk menghasilkan putaran 59,524 rpm dan torsi 151,313 N·m, lebih besar daripada kebutuhan torsi PET sebesar 50,441 N·m. Simulasi menunjukkan safety factor pisau sebesar 3,893 dan rakitan poros sebesar 2,624, sedangkan displacement maksimum rangka sebesar 0,281 mm. Sistem kontrol dirancang menggunakan ESP32, Raspberry Pi 3, sensor inframerah, load cell, servo, monitor, dan rangkaian keselamatan hardwired. Rancangan memenuhi kebutuhan awal kekuatan statik dan fungsi kontrol, tetapi masih memerlukan fabrikasi serta pengujian eksperimental. ***** The problem of plastic waste in Indonesia requires processing technology suitable for the community level, particularly in the size-reduction stage prior to further recycling. This study aims to design a dual-shaft plastic bottle shredder based on the Internet of Things (IoT), determine the technical specifications of the mechanical system, evaluate the strength of critical components, and design the electrical and control systems. Research methods included conceptual design, 3D modelling, mechanical element calculations, preparation of a Bill of Materials, Finite Element Analysis simulation using Autodesk Inventor, frame modal analysis, and the design of the electrical and IoT architecture. The research resulted in a VI three-stage pulley–V-belt transmission with a total ratio of 23.52, producing a shaft speed of 59.524 rpm and a torque of 151.313 N·m—greater than the required PET torque of 50.441 N·m. Simulations showed a blade safety factor of 3.893 and a shaft assembly safety factor of 2.624, while the maximum frame displacement was 0.281 mm. The control system was designed using an ESP32, a Raspberry Pi 3, an infrared sensor, a load cell, a servo, a monitor, and a hardwired safety circuit. The design meets the initial requirements for static strength and control functions but still requires fabrication and experimental testing. Keywords : shredder, designing, waste, environment
