Nowadays development growing fast among the countries in the world. It brings the effect of competitiveness and enhancement social cohesion of our nation, Indonesia. It also needs a system which will support those are. Regional Innovation Systems (SIDa) is a system which can support the development especially for regional and its local wisdom. Banyuwangi is one of the region in East Java that has numbers of potential things in coastal area. Not only that the wide area of agriculture with its agro industry also support the income of Banyuwangi. In order to enhance the effort of SIDa in Banyuwangi, it needs a cluster approach. The cluster approach is considered appropriate to create a model of business strategy planning. The parties involved (stakeholders) is the perpetrator field of agro industry, government institutions, local governments, research and development agencies, educational institutions, innovation support institutions, businesses, and community organizations in the area. From this study is expected to produce agro industrial cluster models that can improve scale agro industry and strengthening of SIDa in Banyuwangi.

There was a phenomenal vessel which has unique hull shape, the shape of the hull is flattened not conventional streamlined as normal vessel. This phenomenal design is dedicated for small vessels such as fishing vessel, patrol vessel and a prototype has been built. This design raised a question regarding the resistance compared to conventional streamline vessel. This paper compares a flat plate vessel with 282.56 ton displacement with a conventional vessel with same displacement and same speed. The resistance comparison was conducted using Computational Fluid Dynamic (CFD) on each ship with speed range 5-10 knots of operational speed. The results of the CFD shows that the resistance of flat plate ship is higher compared to conventional vessel for 5 knots speed. The resistance value for 5 knots of flat plate vessel is 11,618 kN while the conventional vessel shape is 9.23kN. While for 10 knots speed, the flat plate vessel is also higher compared to conventional vessel with 54.53 kN for flat plate and 49.96 kN for conventional vessel.

Abstractas a patrol ship, the offshore patrol vessel (OPV) 80 m has an operational profile consist of several conditions: loitering (10 knots), patrol (18 knots), and interception (22 knots). Applying diesel mechanic propulsion system, load factor of each OPV 80 m's main engine during loitering (10 knots) and patrol (18 knots) conditions in sequence have the value of 7% and 49.54%. The load factor permitted by the engine maker ranges between (60% ~ 90%) MCR, However, By applying hybrid propulsion system, the load factor of the OPV 80 m's shaft motor during loitering condition has the value of 87.26% while the load factor of its main engine during patrol and interception conditions becomes 62.10% and 89.949%.In terms of economic aspects, for 30 years of operation period of OPV 80 m, total of present values of hybrid application is significantly much lower than the diesel mechanical application, with the difference between them is IDR579.205.295.632,-.

Abstractthe increasing number of operating ships resulted in high air pollution from the combustion of the ship's engine. Efforts to utilize alternative energy to reduce ship engine work have been done, one of them is using unlimited alternative energy that is wind where one of its application of is the application of new ships sail, kite sail as auxiliary system of ship propulsion . In this final project purposed to find out the value of aerodynamic force of kite sail and power it can generated , with a CFD method that uses 3 kite sail design forms, rectangular, triangular, and elliptical, with an area of 160 m2 this models are simulated at wind speed variations
