Perancangan Produk AeroMist dengan Menggunakan Metode Nigel Cross

Abstract

Penelitian ini bertujuan untuk merancang produk AeroMist, sebuah perangkat inovatif yang memadukan fungsi diffuser dan dehumidifier dalam satu unit portabel. Proses perancangan dilakukan secara sistematis berdasarkan pendekatan Nigel Cross yang terdiri atas tujuh tahapan utama: klarifikasi tujuan, menentukan fungsi, menciptakan kebutuhan, menentukan fitur teknis, generasi alternatif, penilaian alternatif, dan detail desain. Pada tahap klarifikasi tujuan, digunakan metode pohon tujuan (objectives tree) untuk mengidentifikasi sasaran utama dan subtujuan secara hierarkis. Fungsi produk dianalisis menggunakan metode Black Box untuk memetakan hubungan antara input dan output. Kebutuhan konsumen ditentukan melalui brainstorming dan kuesioner berbasis metode Analytic Hierarchy Process. Hasil akhir dari analisis ini menunjukkan bahwa atribut keinginan (wish) lebih banyak dibandingkan atribut kebutuhan (demand), menandakan bahwa rancangan produk sesuai dengan preferensi konsumen. Karakteristik teknis ditentukan dengan Quality Function Deployment dan divisualisasikan dalam House of Quality. Alternatif desain dikembangkan dengan pendekatan morphological chart, dan dievaluasi menggunakan metode weighted objective. AeroMist dipilih sebagai desain terbaik berdasarkan hasil pembobotan. Pada tahap pengembangan, dilakukan rekayasa nilai untuk menekan biaya produksi dari Rp380.000 menjadi Rp330.000 tanpa menurunkan kualitas. Simulasi produk dengan perangkat lunak SolidWorks menunjukkan massa sebesar 0,217 kg dan tensile strength sebesar 4,079 N/m². Hasil penelitian membuktikan bahwa metode Nigel Cross efektif dalam menghasilkan desain produk yang inovatif, efisien, serta relevan dengan kebutuhan pasar modern.

This research aims to design the AeroMist, This product is designed as a portable solution that serves dual purposes: dispersing fragrance like a diffuser while also reducing humidity levels, similar to a dehumidifier. The design process was carried out systematically based on Nigel Cross’s approach, which consists of seven main stages: goal clarification, function determination, need creation, specification of technical features, generation of alternatives, evaluation of alternatives, and detailed design. In the goal clarification stage, the objectives tree method was used to identify the main goals and sub-goals hierarchically. The product’s functions were analyzed using the Black Box method to map the relationship between input and output. Consumer needs were determined through brainstorming and questionnaires based on the Analytic Hierarchy Process method. The analysis revealed that 'wish' attributes were more numerous than 'demand' attributes, suggesting that the design of the product corresponds well with what consumers are looking for. Technical characteristics were defined using Quality Function Deployment and visualized in the House of Quality. Design alternatives were developed using a morphological chart approach and evaluated using the weighted objective method. AeroMist was selected as the best design based on the weighting results. During the development phase, value engineering was applied to reduce the production cost from IDR 380,000 to IDR 330,000 without compromising quality. Product simulation using SolidWorks software showed a mass of 0.217 kg and a tensile strength of 4.079 N/m². The research results demonstrate that the Nigel Cross method is effective in producing innovative, efficient product that relevant the needs of the modern market.
