Indonesia has thousand islands to be developed. The total number of islands is 17,508. The potential that can be developed on a small island are environment, energy, transportation, education, information, and so on. In this study, focus is development of Maratua island, located in the district of Berau in East Kalimantan Indonesia. The potential of the island is development of marine tourism. In this case, Sustainable Island Development initiatives (SIDI) implemented to address the above challenges through multidisciplinary research activities. This research is starting from the transport sector, health, education, energy and implementation of information technology. In this context, the development of digital education is very important. This research provides solutions to the educational development of practical and suitable for the Maratua Island. This research develops the role of information and communication technology for teaching and learning activities island communities, examines the role of technology as a supplement teaching and learning process. In addition, this research also aims to design a physical architecture and digital education system that can be implemented in small islands in Indonesia, designing a learning method to support the teaching and learning process, and educating stakeholders about the concept of digital education

Crude oil contains mixed of hydrocarbons, the most commonly found molecules are alkanes (paraffins), cycloalkanes (naphthenes), aromatic hydrocarbons, or more complicated chemicals. In the process of taking crude oil in subsea pipeline system with depth 1200 meters, the contents of crude oil like sulfur, paraffin, asphalt could deposit in the wall of the pipe because of the different temperature between crude oil and wall of the pipe. The deposition can make blockage to the pipe and cause crude oil flow to be slow or stop. In this bachelor thesis, will be design double walled pipe for Subsea pipeline system with depth 1200 meters and simulation double walled pipe to knowing the impact of double walled pipe to crude oil flow in Subsea with depth 1200 meters. Based on the simulation that has been done, using double walled pipe could stabilize the temperature between crude oil and wall of the pipe. It shows that the average of temperature decrease using double walled pipe is only 0.125 K for 12 meters. So, it could get the conclusion based on the simulation of double walled pipe that the impact to crude oil flow is there’s no blockage in the pipe and the crude oil flow will steady.

Marine business is one of the largest businesses in the world. Exports and Imports of human necessities in the majority are using ships. This is because of the ratio between the goods that can be delivered on each trip and the number of trips it can go to fulfill this. This makes the shipping or transport cost-efficient. But the continuous growth of the world population and its standard of living creates an ever-increasing dependency for the world economy on international trade. Therefore a good shipping company will always develop a better way of shipping together with more efficient and optimized voyage planning. To increase the efficiency of shipping, companies try to reduce the cost of almost everything. Therefore, one of the options for improving the efficiency of shipping is by increasing the efficiency of the ship itself. The ship efficiency is not only determined by how fast the ship and how much the ship can load, but also how much fuel does the ship consume for each operation. An investigation of the engine efficiency must be done. The investigation will be done by using an engine model in Simulink to create a similar engine model to the real engine. Then simulate the dynamic process of the engine, which will affect the consumption in general. Therefore the consumption of the engine can be analyzed. The results of this bachelor thesis is an explanation of how to develop the engine model. This includes the explanation of what is the engine efficiency and the engine parameters that affect efficiency, such as engine consumption, engine losses, etc. The model development includes the change in parameters and model structure. Then a simulation is done to compare the results with the measured data. From this process, the model can be considered satisfactory when the results are similar to the measured data.

The thermal oil system is one type of heater that widely used on ships. The system is an important system used to heat fuel that will be used for the operation of the main engine, auxiliary engine, and boiler. This system has been installed on 17500 LTDW Product Oil Tanker, MT. Parigi, but not yet tested so that it does not know whether the system is able or not to transfer heat from heating equipment (boiler and economizer) to each fuel tank in accordance with the desired value. Therefore, this research performs an engineering evaluation in term of heat transfer analysis to ensure that the heat transfer process of thermal oil from heating equipment to the fuel tanks is already meeting the required temperature or not. This analysis is done by using thermodynamic equation, namely heat balance equation and heat loss equation. The result shows that the heat transfer of thermal oil to each fuel tank corresponds to the desired value, namely 180oC for the thermal oil inlet temperature to each fuel tank and 140oC for the thermal oil re-enter temperature to the heating equipment.
