Low air draft passenger boat for inland waterways navigation is a design of a boat that is suitable for navigation in the parts where there are bridges that are low enough to be navigate by regular dimensions passenger boat. Therefore for a passenger boat to navigate in Klang River from LRT Kampung Baru to LRT Tun Sambanthan for 4km long the air draft of the boat must meet the specifications of 2.0m to have a safety margin for the boat as well as 11m length for the boat to manoeuvre easily to go to and fro the route. The boat is design using Maxsurf software and the linesplan and general arrangement is design using AutoCAD. The passenger boat is able to accommodate for 54 people per trip for a speed of average 10 knots or 18.52 km/h. the boat also equip with safety that needed for the passenger to be safe during the trip as well as for their comfort is being taken into account. The economic analysis was carried out for building the boat and for operating the boat as a passenger vaessel in Klang River.

Ocean Thermal Energy Conversion (OTEC) is a clean marine renewable energy using temperature difference between the sea surface and the deep ocean to rotate a generator to produce electrical energy. As Indonesia is an equatorial country located at latitudes less than 20 degrees covered by 77 % ocean, thousand islands, strain and many difference of topography, OTEC is very compatible to be built in Indonesia. This paper discussed on sea temperature profiles at Siberut island-Mentawai, Sumatera Barat-Indonesia. The Siberut island-Mentawai is one of potential areas for OTEC in Indonesia. The Siberut island-Mentawai has a hot and humid tropical rainforest climate, with an annual rainfall of 4,000 mm with temperatures range 27 - 31 0C and humidity averages 81 - 85%. The sea temperature was measured using thermocouple, It founded that the Siberut island-Mentawai has potential OTEC due to the gradient temperature more than 20 Celcius.
