The potential wealth of marine resources such as marine fisheries resources is owned by Indonesia. The wealth of marine resources has not been utilized and managed optimally. Today, there are many businesses driven in various fields. The business of building floor crafts from sea shells (anadara grandis) can be pioneered into one form of business. Buton Regency is an archipelago, more than 80% of its territory consists of sea. During this time, shellfish cultivated by fishermen only used the meat, while the shell removed and became waste. This research aims to utilize shell waste into floor material. The method used in this research was exploration method. The data began with the selection of materials, work tools, and stages of manufacture. Information from various sources is captured and interpreted into a creative idea. The process of analysis was done qualitatively, so it was obtained and raised the shape of the floor. This study concludes that the use of waste shellfish shells into composite floor material is done in three stages. In the first stage, prepared work tools such as glass molds, measuring cups, stirring spoons, brushes, flooring boards, measuring tools, hammers, cutter knives, sandpaper and plastic. The second stage is prepared work materials such as shells, hardener, resin oil, and mirror glass. The third stage is made of floor like shell stage filled with resin oil; The printed floor stage is like smearing a glass mirror on the mold, the resin oil is mixed with hardener, the composite mixture is poured into the mold, the shells are placed in the mold, the shells are poured again with resin oil, and hardener; Stage of removing from glass mold and; finally the floor is given the ballast.
