Mini Production Suction Dredge (MPSD) has been made for the people of Bangka Belitung Province Indonesia which is known as a cheap, safe and straightforward technology ship to mine tin sand from surface land under the sea level. This MPSD creates more safe production operation since the previous ships by using a traditional small boat for catching the fish. The main reason why this MPSD was created because there is no diving activity for an operator to drive the suction pipe flexibly under the sea which in some cases make the divers have problems and get injured seriously or fatality. The MPSD is a welded construction of 4 x 10 meters ship which is equipped with the suction unit, 24 HP diesel engines to drive two suction pumps, the tin separation jig and the steering winch. The basic construction of the dredge consists of 2 sides of 0.8-meter diameters x 10 metersof the steel pontoon. It operates on the sea waves which take the sand up to 15 meters deep from the mean sea level and allows no diving activity in 1 mile away from the coastline. Through its operation, the MPSD operated more stable and safer than the previous operation.
