Abstract

Desa Karyawangi merupakan salah satu desa di wilayah Kabupaten Bandung Barat dan termasuk ke dalam wilayah agraris. Desa Karyawangi, dengan mayoritas penduduknya bermata pencaharian sebagai petani dan memiliki potensi besar dalam meningkatkan produktivitas pertanian. Namun, efisiensi proses pelubangan mulsa masih menjadi tantangan utama yang perlu segera diatasi. Metode manual pelubangan mulsa yang masih banyak digunakan terbukti memakan waktu, tenaga dan sering kali kurang presisi. Penelitian ini bertujuan untuk mengembangkan alat pelubang mulsa inovatif yang dirancang untuk meningkatkan efisiensi dan ergonomic kerja petani. Proses pengembangan meliputi desain, pembuatan prototipe, dan pengujian lapangan untuk mengevaluasi kinerja alat. Hasil pengujian menunjukkan bahwa alat ini mampu mempercepat proses pelubangan mulsa dibandingkan dengan metode konvensional, dengan tingkat presisi lubang yang seragam. Alat pelubang mulsa ini diharapkan menjadi model bagi pengembangan alat pertanian sederhana yang mendukung keberlanjutan sektor agraris.

Abstract

Braiding machines are essential equipment in the textile industry for producing precise fibber or wire interlacements. Most conventional braiding machines in Indonesia are aging and lack adequate technical documentation. As a consequence, maintenance, component replacement, and component reproduction processes become difficult to perform. This study aims to recover technical data and develop the take-up mechanism of a conventional braiding machine through a reverse engineering approach. The research methodology consists of component identification through disassembly, dimensional measurement, 3D CAD modelling, component design modification, preparation of technical drawings, followed by assembly and functional testing. The results show that the modified component design has a simpler geometry, resulting in more efficient assembly and maintenance processes. Functional testing demonstrates that all components operate in accordance with the original mechanism, while performance testing indicates that the take-up system is capable of maintaining constant yarn tension and producing uniform braiding within a speed range of 100–160 RPM. Statistical analysis using an X̄ control chart confirms that the braiding quality remains within statistical control limits without significant deviations. Therefore, this study concludes that the reverse engineering method is effective in providing comprehensive technical documentation, extending machine service life, and supporting local manufacturing independence.Keywords - Dokumentasi Teknis, Mesin Braiding, Reverse Engineering, Sistem Penarik, X-Chart.

Abstract

The main constraint in porang processing are porang chips thickness uniformity and high calcium oxalate content. There are three stages of porang processing are washing, slicing, and boiling. The machine designed in this research combining the function of three machines : washing machine, slicer, and boiler. First, porang roots is placed into the hopper, then porang is cleaned using rotating washing brush with the translational movement of the screw conveyor. After that, porang is sliced and boiled in NaCl solution to reduce its calcium oxalate content. This research uses VDI 2222 design methodology including planning, conceptualizing, designing, and finishing. The design and validation process of critical components is carried out using CAE (Computer Aided Engineering) software. After going through the design process, a machine design was produced with a production capacity of 500 kg/hour.
