Development of ecotourism floating restaurant in Surabaya City

In the 18^th century, Kalimas's river serves as a workspace, marketing space, and transportation routes for residents of Surabaya. Although the current condition of Kalimas river has changed a lot, but Kalimas's river has good potential of water tourism and transportation facilities. Therefore, the Surabaya city government setup a policy to revitalize the Kalimas's River. The submarine monument area as one of Surabaya's landmarks next to Kalimas's River will be developed as a 'Riverside Center Business Center'. One feasible way to support the city government program is the development of a floating restaurant. Floating restaurant is just a place to eat, when doing business negotiations or family tours. The concept of floating restaurant development based on ecotourism. Hence, this restaurant is designed environmentally friendly, empowering local people, and become a means of learning and education. The eco-friendly concept is manifested in a flat outward-side asynchronous catamaran form and battery-based electric propulsion systems and solar panels. The menus are provided by local vendors along the river bank of Kalimas so the local food supplier will be more empowered.
