Plastic garbage is one of the elements that causes the pollution and especially pollution in the sea. The amount of rubbish in the waters has indeed become one of the problems which has not been resolved. It comes from the activities of human who throw garbage into the sea, the lack of mutual cooperation activities and public awareness in disposing of garbage in its place. The aims of this research are to make a suction tool and trash collector to help the community in collecting marine trash on the surface of the sea, so the community does not need to manually collect or clean up trash in the port area or residents homes near coastal. In this study, the researcher used LDR sensor to respond the presence of garbage, DC motors to move the garbage nets, relay modules as the regulators of the life of the pump, and limit switches to turn off and turn on the DC motors, and also GSM900 Modules as notification tools which is to send a Short Message Service (SMS) to the user that the garbage is full and ready to be picked up. The result of the study was obtained that the device are able to take waste with an average weight every hour, 0.3 kg and the maximum weight that can be lifted nets 0.5 kg and minimum weight around 0.1 kg. with the most type of waste in the form of plastic waste , organic waste and other household waste in small size.
