Penelitian ini bertujuan untuk melakukan penyusunan konsep produk untuk pembuatan prototype dengan mempertimbangkan suara konsumen (VoC) dan mengukur nilai investasi dari produk cairan pelapis permukaan air pada kloset. Desain produk adalah salah satu tahap yang paling penting dalam memulai suatu usaha menjual produk. Desain produk yang sesuai dengan permintaan konsumen berasal dari kebutuhan konsumen. Oleh karena itu, penelitian product engineering ini menggunakan pendekatan Quality Function Deployment (QFD). Analisis kelayakan investasi dilakukan dengan mencari nilai Net Present Value (NPV), Internal Rate of Return (IRR), Profitability Index (PI) dan Payback Period. Tahap yang dilakukan yaitu penentuan segmentasi pasar dan dilanjutkan dengan penyebaran kuisioner pendahuluan terhadap 24 responsden untuk mengetahui atribut apa saja yang akan muncul sebagai voice of customer. Kemudian tingkat kepentingan konsumen pada atribut kepentingan dikelompokkan menjadi 5 atribut utama, yaitu aroma, desain, portabilitas, efektivitas, dan harga. Hasil pengolahan data menunjukkan atribut desain memiliki hubungan yang paling kuat dengan respons teknis logo dan warna kemasan produk dengan nilai bobot sebesar 42.336. Pengembangan produk diprioritaskan pada respons teknis proporsi/ komposisi bahan baku, kemudian disusul dengan desain logo, warna, dan ukuran kemasan serta jenis bahan baku. Nilai analisis investasi kelayakan dengan metode payback period sebesar 8,63, bulan dan NPV sebesar Rp 10.612.209, IRR sebesar 22,32% dan PI sebesar 1,75. Hal ini menjadi dasar bahwa investasi layak dilakukan. Abstract[Product Engineering and Feasibility Analysis of Investment of The Development Water Surface Coating Products on Closets] The success of selling a product goes hand-in-hand with the product design on the market. To effectively create a competitive product for the market requires a great deal of product planning, design, and development. In preparing the product development plan will also requires an extended analysis of costs and investment value that will be carried out in the future. This study aims to develop a concept for making a product prototype by considering the consumer's voice (VoC) and measuring the investment value of a coating liquid product for toilet water’s surface to minimize the smell of feces. Product design is one of the most important stages in starting a business selling products. Product design in accordance with consumer demand comes from consumer needs. Therefore, the product engineering study uses Quality Function Deployment (QFD) method, whereas the investment feasibility study uses Cost of Goods Sold (CoGS), Profit and Loss Analysis (P&L), Payback Period (PP), Net Present Value (NPV), Internal Rate of Return (IRR), and Profitability Index (PI). The next step is specifying market segmentation and followed with distributing initial questionnaire to 24 people to determine what kinds of attribute will be selected as a voice of consumer’s. Then, all of the attributes will be grouped into 5 customer’s requirements characteristics which are scent, design, portability, effectiveness, and price. The design characteristic has strongest relation with technical response of logo and packaging color with weight value of 42.336. In product development, material proportion is prioritized, followed by logo design, color, product’s size, and types of ingredients. The result of investment feasibility study are 8.63 for payback period, Rp 10.612.209,- for projected NPV at 10th period, and 22,32% IRR. This becomes the the basis of reasoing why investment is feasible. Keywords: Product Development; Quality Function Deployment; Investment Feasibility Analysis; Product Design
