Penerapan Metode Nigel Cross pada Desain Produk Rest-O-Sphere

Abstract

Rendahnya tingkat kesadaran mahasiswa dalam mengelola waktu aktivitas dan istirahat sering memicu kelelahan fisik serta penurunan kesehatan mental. Walaupun aplikasi pengingat digital telah tersedia luas, efektivitasnya dalam memberikan intervensi langsung dinilai masih terbatas. Oleh karena itu, penelitian ini bertujuan merancang solusi fisik inovatif bernama Rest-O-Sphere. Perangkat multifungsi ini menggabungkan sistem pengingat mandiri otomatis dengan fitur penunjang kenyamanan, termasuk lampu tidur LED, kipas penstabil suhu ruangan, dan sistem audio. Metodologi penelitian mengadopsi kerangka kerja perancangan Nigel Cross, yang mencakup tahapan klarifikasi tujuan, penetapan fungsi, penyusunan kebutuhan, penetapan karakteristik, hingga pengembangan detail rancangan. Pada tahap identifikasi kebutuhan, metode Quality Function Deployment (QFD) digunakan untuk mengubah keinginan konsumen menjadi karakteristik teknis. Melalui matriks House of Quality, dilakukan analisis hubungan antar atribut produk, tingkat kesulitan teknis, serta perbandingan kinerja terhadap pesaing. Hasilnya menunjukkan seluruh parameter teknis berkontribusi secara signifikan terhadap kualitas akhir produk.Selanjutnya, beberapa alternatif kombinasi solusi dikembangkan menggunakan peta morfologi (morphological chart). Alternatif tersebut dievaluasi menggunakan analisis pembobotan tujuan melalui metode perbandingan berpasangan (pair-wise comparison), sehingga terpilih rancangan dengan tingkat stabilitas dan nilai kepentingan tertinggi sesuai ekspektasi konsumen. Penelitian ini juga menerapkan metode rekayasa nilai (value engineering) untuk mengoptimalkan biaya produksi tanpa mengorbankan nilai fungsional perangkat. Terakhir, validasi rancangan diperkuat oleh simulasi perangkat lunak SolidWorks untuk memastikan kekuatan mekanik dan kelayakan desain sebelum memasuki tahap manufaktur. Disimpulkan bahwa rancangan Rest-O-Sphere layak diproduksi secara teknis dan ekonomis.

The low level of awareness among university students in managing their activity and rest time often triggers physical fatigue and a decline in mental health. Although digital reminder applications are widely available, their effectiveness in providing direct intervention is considered limited. Therefore, this research aims to design an innovative physical solution named Rest-O-Sphere. This multifunctional device combines an automatic self-reminder system with comfort-enhancing features, including an LED night lamp, a room temperature-stabilizing fan, and an audio system. The research methodology adopts the Nigel Cross design framework, encompassing the stages of clarifying objectives, establishing functions, setting requirements, determining characteristics, and improving design details. In the needs identification stage, Quality Function Deployment (QFD) was utilized to transform consumer desires into technical characteristics. Through the House of Quality matrix, an analysis was conducted to evaluate relationships between product attributes, technical difficulty levels, and competitor performance. The results indicate that all established technical parameters significantly contribute to the final product quality. Furthermore, several alternative solution combinations were developed using a Morphological Chart. These alternatives were evaluated using objective weighting analysis through the Pair-Wise Comparison method. Consequently, the design demonstrating the highest stability and importance value aligning with consumer expectations was selected. This research also applies Value Engineering to optimize production costs without sacrificing the device's functional value. Finally, design validation is strengthened by SolidWorks software simulation to ensure mechanical strength and design feasibility before the manufacturing stage. It is concluded that the Rest-O-Sphere design is technically and economically feasible for production.
