Abstract

The sabit, a traditional agricultural instrument for harvesting oil palm fruit bunches, is normally made out of a curved metal blade and a short wooden handle. The current Sabit Teras Premium by Teras Tegas Argotech Sdn. Bhd. has gives harvesting efficiency and user comfort. The goal of this research is to redesign the sabit in order to optimise its curvature, hence improving cutting efficiency and performance. An indepth investigation of the existing Sabit Teras Premium design, focused on blade curvature, was carried out utilising a reverse engineering approach and 3D modelling in SolidWorks. The techniques of analysis Linear Static, and Dynamic were used. Linear Static Analysis using Simulation Xpress been done to assess the displacement, stress and safety factor. Hence, with data get from safety factor used to find the fatigue using Newton Interpolation Method and it show the improvement design had higher fatigue than existing. Meanwhile, Dynamic Analysis done by ANSYS (FLUENT) to indicate the velocity, pressure, and viscosity exerted on the sabit, providing information about its lifespan. During these assessments, both existing and improvement sabit designs were subjected to varied loading situations that simulated actual usage forces and fatigue. The results showed that the improvement designs of sabit outperformed the previous one in terms of linear static and dynamic analysis, showing higher efficiency, performance, and durability. The validation method, which included Coefficient of Variation (CV) and Design Efficiency (DE) measurements, confirmed that existing and imprvement design shown the optimised design achieves maximum capacity, enhancing cutting accuracy and minimising user effort.
