A Study of the effectiveness Fin Stabilizer on Unsada Water Tour Bus to Comfort the Rolling Period to Support Toba Lake Tourism

Abstract

Lake Toba is one of the five super priority national tourist destinations. To support Lake Toba tourism. a suitable and safe mode of transportation is needed and to be able to provide an attraction for tourists. See this opportunity. we plan to make this mode of transportation. The Air Unsada Tourism Bus is one of the modes of transportation that is a pioneer of new modes of tourism transportation in Indonesia. especially on Lake Toba. North Sumatra. The Unsada Water Tourism Bus is an amphibious bus that can move both on land and in water. The Unsada Air Tour Bus is specially designed using fin stabilizers on the bus body. like the hull of a ship in general. The purpose of this research is to design a Water Tourism Bus that can provide comfort and safety for tourists. in this case that is how to minimize the rolling time on the Air Unsada Tourism Bus to pay attention to the condition of Lake Toba's waters which is quite extreme. In designing this bus using the dimensions of a conventional bus with a length of 13.115 meters. 2.5 meters wide. As high as 3.8 meters. and a double decker used for the roof so that tourists can enjoy views of Lake Toba. The method used for the calculation is IMO stability level 2 and also uses Indonesian land transportation regulations contained in government regulation no 55 chapter 3 part 3d 2012. For calculations and analysis using the Maxsurf software. Meet the IMO standard parametric rolling level 2. The results obtained are 0,000239 below the 0.06 standard.
