Abstract

Sumpit merupakan senjata tradisional suku Dayak yang saat ini telah mengalami perkembangan, terutama dalam proses produksi sumpit atau peluru sumpit. Selama ini proses produksi khususnya untuk peluru sumpit masih dilakukan secara tradisional. Kelemahan sistem produksi secara tradisional adalah kurang presisi dan tidak seragam. Upaya penyelesaian masalah dilakukan dengan mengembangkan mesin pembentuk ekor peluru sumpit menggunakan sistem pemakanan otomatis. Penelitian ini bertujuan merancang bangun dan menguji kinerja mesin pembentuk ekor peluru sumpit dengan pemakanan otomatis. Tahapan penelitian meliputi proses pembuatan mesin, penulisan koding program, uji verifikasi mesin, uji kinerja mesin, pengambilan dan analisis data. Uji kinerja yang dilakukan pada mesin berupa pengukuran kapasitas produksi dan keseragama ukuran. Mesin hasil rancang bangun memiliki dimensi panjang 62 cm, lebar 60 cm, tinggi 110 cm. Mesin terdiri atas 3 motor yaitu motor pemutar ekor peluru menggunakan motor listrk 125 watt, motor pemotong menggunakan motor listrk 125 watt dan motor penggerak eretan menggunakan motor stepper. Pergerakan motor dikontrol oleh mikrokontroler Arduino UNO. Hasil pengujian menunjukkan bahwa mesin pembentuk ekor peluru sumpit memiliki kapasitas produksi rata-rata 18,10 butir/jam. Hasil pengujian keseragaman ukuran menunjukkan bahwa rata-rata keseragaman dimensi A dan B masing-masing sebesar 98,93% dan 98,94%, sedangkan dimensi C dan D mencapai 97,85% dan 96,89%.

Abstract

The purpose of this study is to describe the process and results of developing a Hydraulic Hot Press machine for molding areca palm sheath sheets into tote bags. Areca palm sheaths were selected as the sample material due to their abundance as organic waste in Sambas Regency, which has not yet been utilized in waste processing. This research was conducted through five stages: literature review, tool design, preparation of tools and materials, fabrication, and testing. The development process of the Hydraulic Hot Press included determining the dimensions, constructing the frame, assembling the heating system, and conducting functional tests. The press was designed with dimensions of 100 cm in length, 60 cm in width, and 130 cm in height. It was equipped with a heating system powered by an LPG gas cylinder as the main energy source, with heat delivered through a piping system to the main pressing point. The results indicated that when the steel base plate of the press was subjected to hydraulic pressure and direct heating, thermal expansion occurred, causing slight bending of the steel foundation. This condition led to less-than-optimal molding results of the areca palm sheath sheets into tote bags.
