Desain Alat Pengupas Kulit dan Inti Nanas (Ananas comosus L.) dengan Sistem Pneumatik

Abstract

Pineapple (Ananas comosus L.) is a tropical fruit extensively consumed and processed into various food products. Manual peeling of pineapple skin and core is labor-intensive, time-consuming, and poses occupational safety risks. This research aims to develop the design of a pineapple skin and core peeling machine employing a pneumatic system and to evaluate its performance through computational simulation using SolidWorks software. The research methodology comprises functional and structural design analysis, engineering calculations, technical drawing development, static structural analysis, and kinematic simulation. Design specifications reveal overall dimensions of 65 cm × 40 cm × 60 cm, incorporating principal components: stainless steel 204 cutting blades, SC 50×200 pneumatic cylinder, 1 HP compressor with 8 bar operating pressure, and ST 37 steel L-profile structural frame. Engineering calculations establish the required peeling force of 88.3 N at 0.451 bar operating pressure. The pneumatic actuation system generates forward and retraction piston forces of 982.14 N and 973.09 N respectively, consuming 2.92 liters of compressed air per operational cycle. Finite element analysis demonstrates maximum frame stress of 72.58 MPa, displacement of 0.494 mm, and safety factor of 1, confirming adequate structural integrity and load-bearing capability. Kinematic simulation validates consistent blade operation within a 5-second operational cycle. The proposed design presents a technically feasible solution for prototype fabrication, potentially enhancing operational efficiency in pineapple processing applications.
