On the sidelines of the launch of a solar -powered speedboats carried along East Java Governor Soekarwo ITS Vice Rector Prof. Saso Herman , one of the " drivers " that explain Jalapatih ship " Jalapatih " it has actually been initiated since 2012 .
" Shipbuilding is actually only a year , but we were able to find links to the Netherlands , including solar cell, we use an assistance exercise any of the LEN ( SOE ) . We did not design the solar cell , because it will be given committee , but the design of the boat and motor drive is homemade , " he said .
He explained that the first race was followed ITS is a solar -powered racing boat with the distance as far as 200 kilometers across seven provinces in the Netherlands . " We will colonize the former colonizers , " he said , to laughter from the audience and the Governor of East Java .
Meanwhile , other drivers , Viky Suryanto , explaining ship 5 meters long and 1.5 meters wide that has a speed of 6.5 to 8 knots (equivalent to 12 km / h ) with a power of 1 kilowatt , but the ship has a lithium battery powered 1 , 5 kwh .
" So , Jalapatih ship has a maximum power of 2 kWh of solar cell and batteries available . Lithium ion batteries There were 119 ( special solar batteries ) that we have, but not Jalapatih excellence in solar cell or battery that is there , but the system that we have designed , " said the student of 4th semester Shipping System Department of ITS .
Therefore , he said , victory is not only determined the speed of the ship , but the intelligence of the " driver " in regulating the speed of the ship , because if it's too tight will also make the batteries run out quickly , but if it is not too slow either .
