This study presents the design and structural analysis of a palm frond shaving machine with a production capacity of 100 kg/hour, aimed at improving the efficiency of the traditional manual process used by craftsmen. The manual method is time-consuming and labor-intensive, limiting production to approximately 2 kg/hour. To address this issue, a mechanical design was developed using SolidWorks 2017 software. The research involved consumer surveys to identify user requirements, followed by concept generation, technical and economic evaluation, and simulation analysis of the selected design. Among three design variants, the second concept—featuring a stone grinder cutter system, UNP steel frame, V-belt transmission, and gasoline engine—was selected as optimal based on combined technical and economic scores. Structural simulation results indicate that the frame, made from UNP 50 steel profiles, exhibits acceptable stress, displacement, and safety factor levels under an applied load of 10 kg. This study offers a viable solution for small-scale industries to process palm fronds into usable sticks efficiently.

This study successfully designed and analyzed a palm frond shaving machine capable of producing 100 kg of shaved fronds per hour.Based on surveys and variant evaluations, Concept 2—with its stone grinder mechanism and gasoline engine—was chosen for its superior technical and economic performance.Structural analysis using SolidWorks confirmed the machines safety under operational load conditions.Von Mises stress remained within the yield strength of UNP steel, displacement was minimal, and the safety factor exceeded recommended thresholds.These results indicate that the machine is feasible for real-world use in palm oil-producing communities.

Berdasarkan penelitian ini, terdapat beberapa saran penelitian lanjutan yang dapat dilakukan untuk meningkatkan efisiensi dan keberlanjutan mesin pemotong daun kelapa. Pertama, perlu dilakukan pengembangan prototipe mesin secara fisik dan pengujian kinerja di lapangan untuk memvalidasi hasil simulasi dan mengidentifikasi potensi perbaikan. Kedua, penelitian dapat difokuskan pada pengembangan sistem otomatisasi untuk proses pemotongan, seperti penggunaan sensor dan kontroler untuk mengatur kecepatan dan ketebalan potongan secara presisi, sehingga meningkatkan kualitas produk dan mengurangi ketergantungan pada operator. Ketiga, eksplorasi penggunaan material alternatif yang lebih ringan dan ramah lingkungan untuk rangka mesin, seperti komposit serat alami, dapat menjadi fokus penelitian selanjutnya untuk mengurangi berat mesin dan dampak lingkungan.
