Perancangan Produk Sensebox Menggunakan Metode Quality Function Deployment (QFD)

Abstract

Perancangan produk memerlukan metode yang dapat mengonversi kebutuhan pelanggan ke dalam spesifikasi teknis dengan terstruktur. Pada perancangan produk Sensebox, digunakan pendekatan Quality Function Deployment (QFD) untuk memastikan atribut yang menjadi preferensi konsumen dapat dipenuhi melalui parameter teknis produk. Penelitian ini dilakukan untuk menentukan spesifikasi teknis produk Sensebox sesuai kebutuhan konsumen menggunakan metode QFD. Tahapan yang digunakan meliputi identifikasi spesifikasi produk, penetapan tingkat kepentingan atribut, penyusunan matriks relasi antara atribut produk dengan spesifikasi teknis pada House of Quality (HoQ), identifikasi hubungan antar spesifikasi teknis, serta penetapan tingkat kesulitan, tingkat kepentingan, serta estimasi biaya. Hasil penelitian mengindikasikan bahwa atribut produk yang selaras dengan preferensi konsumen mencakup ukuran, bahan, berat, kapasitas baterai, jenis penutup, bentuk, warna, serta fitur tambahan berupa monitoring nirkabel, sensor suhu dan kelembapan, dan sterilisasi . Karakteristik teknis memiliki tingkat kepentingan yang berbeda, di mana radius jangkauan tergolong kurang penting, sedangkan dimensi produk, tegangan sistem, total massa, ketahanan daya, ketebalan wadah, dan volume ruang internal tergolong penting . Tingkat kesulitan terbagi menjadi dua kategori, yaitu cukup mudah dan sangat sulit, sedangkan perkiraan biaya terbagi ke dalam kategori rendah dan sedang. Hasil tersebut menunjukkan bahwa metode QFD mampu mengidentifikasi karakteristik teknis produk Sensebox berdasarkan kebutuhan konsumen secara terstruktur.

Product design requires a method capable of systematically translating customer needs into technical spesifications. In product design of  Sensebox, the Quality Function Deployment (QFD) approach is used to ensure that the attributes required by customers can be fulfilled through technical parameters. This study is conducted to define the technical characteristics of the Sensebox product based on customer needs using the QFD method. The stages employed include the identification of product attributes, determination of attribute importance levels, construction of the interaction matrix of product attributes and technical characteristics in the House of Quality (HoQ), identification of relationships among technical characteristics, and determination of difficulty level, degree of importance, and estimated cost. The results show that the product attributes in accordance with customer needs include size, material, weight, battery capacity, closure mechanism, shape, color, as well as additional features such as wireless monitoring, temperature and humidity sensors, and sterilization. The technical characteristics have varying levels of importance, where the coverage radius is categorized as less important, while product dimensions, system voltage, total mass, power endurance, container thickness, and internal volume are categorized as important. The level of difficulty is classified into two categories, namely moderately easy and very difficult, while the estimated cost is categorized into low and moderate levels. These results indicate that the QFD method is capable of systematically identifying the technical characteristics of the Sensebox product based on customer needs.
