Developing countries such as our country, losses due to weeds are as large as losses due to pests. Weed water hyacinth reduces the efficiency of irrigation systems, disturbing and widespread so that water waste due to evaporation and also reduces the flow of water. Water loss by evaporation (evapotranspiration) 7.8 times more than open water. In Swamp Pening, Weed Water can cause floating islands that disrupt the penetration of sunlight to the surface of the water, reduce oxygen solubility in water (DO: dissolved oxygens) and reduce water productivity. The wreck of the hyacinth will settle and speed up the silt. Increase the habitat vector disease, reduce aesthetics and interfere with water transportation.

The benefits obtained from this activity are in the form of obtaining design details and prototypes of safety tools to overcome hyacinth. Solution is prioritized on the design of the cavement that can be used on existing aluminum boat designs
