Trash is one of the biggest problems on earth. This waste can pollute and endanger the natural wildlife and environment of the lake. The Solar Powered Aquatic Trash Boat (SPAT) project is dedicated to realizing an eco-friendly, remotely operated vehicle, solar-powered trash boat concept. The remote control function allows floating trash to be picked up from the middle of the lake, which is usually unreachable by traditional trash collection methods that require the mobilization of many people to move along the lake shores. People have to go to the shore of the lake and wait for the garbage in the middle of the lake to be swept away by the lake’s current. Construction of the vehicle was completed, and continued by the testing of its electrical, buoyancy, navigation, and trash collection ability. A buoyancy test showed that the boat floats perfectly with the weight of 11 kg. Navigational tests showed that the boat can travel at a maximum speed of 1.2 km/h and can be remotely controlled within a range of 150 meters. Electrical tests have proven that the boat can sail continuously without interruption as long as it is connected to the solar panels. In the absence of sunlight, the boat still can sail for 5 hours. For energy cost comparison, solar power is free but when using conventional home power electricity, the estimated annual electricity bill is about $5.4 USD, or about 78,000 Indonesian rupiah. Trash collection performance tests have proven that the boat’s net can collect around 1 kg of garbage in one collection round before it returns to shore for disposal.
