Abstract

Fire jet nozzle merupakan komponen penting pada sistem pemadam kebakaran yang berfungsi mengarahkan aliran air menuju titik api. Namun, desain fire jet nozzle konvensional masih memiliki beberapa kelemahan, seperti potensi kebocoran pada sambungan, jumlah komponen yang relatif banyak, serta penggunaan material kuningan yang memiliki bobot cukup berat sehingga memengaruhi efisiensi penggunaan dan proses perakitan. Penelitian ini bertujuan untuk merancang ulang fire jet nozzle menggunakan metode Design for Manufacture and Assembly (DFMA) dengan menerapkan material Carbon Fiber Reinforced Polymer (CFRP), mengurangi jumlah komponen, serta mengembangkan sistem sambungan untuk meminimalkan kebocoran. Metode penelitian dilakukan melalui studi literatur, perancangan desain menggunakan Computer Aided Design (CAD), pembuatan prototipe, serta analisis performa terhadap desain yang diusulkan. Hasil penelitian menunjukkan bahwa jumlah komponen berhasil dikurangi dari tiga menjadi dua komponen melalui penyederhanaan desain. Selain itu, penerapan sistem coupling machino yang dikombinasikan dengan mekanisme male-female menghasilkan sambungan yang lebih rapat dengan potensi kebocoran yang lebih rendah. Penggunaan material CFRP juga menghasilkan desain fire jet nozzle yang lebih ringan dibandingkan material kuningan. Berdasarkan hasil penelitian, redesign fire jet nozzle berbasis DFMA mampu meningkatkan efisiensi perakitan, meminimalkan potensi kebocoran, dan meningkatkan performa nozzle secara keseluruhan. ***** Fire jet nozzle is an important component in a firefighting system that functions to direct water flow toward the fire source. However, conventional fire jet nozzle designs still have several limitations, including leakage potential at connection points, a relatively high number of components, and the use of brass material with considerable weight, which affects efficiency and assembly processes. This study aims to redesign the fire jet nozzle using the Design for Manufacture and Assembly (DFMA) method by implementing Carbon Fiber Reinforced Polymer (CFRP) material, reducing the number of components, and developing an improved connection system to minimize leakage. The research method was conducted through literature studies, Computer Aided Design (CAD)-based design development, prototype fabrication, and performance analysis of the proposed design. The results showed that the number of components was successfully reduced from three to two through design simplification. In addition, the implementation of a coupling machino combined with a male-female mechanism produced a tighter connection with lower leakage potential. The use of CFRP also resulted in a lighter fire jet nozzle design compared to brass material. Based on the results, the DFMA-based redesign successfully improved assembly efficiency, minimized leakage potential, and enhanced the overall performance of the fire jet nozzle.
