Abstract
The purpose of this experiment is to know the influence of a single guide vane position and angle to the performance of a cross-flow wind turbine. The cross-flow wind turbine was positioned at the discharge outlet of a cooling tower model to harness the discharged wind for electricity generation. A guide vane was used to enhance the rotational speed of the turbines for power augmentation. Various position and angle of attack of the guide vane were tested in this experiment. To avoid negative impact on the performance of the cooling tower fan and to optimize the wind turbine performance, the turbine position on the discharge wind stream was also studied. The result showed that cross-flow wind turbine with a guide vane attached at the right position had a higher coefficient of power than cross flow turbine without guide vane. A crossflow wind turbine with the guide vane at the position of 150 mm from the center and 30° angles had the highest coefficient of power of 0.49. Comparing to the wind turbine without guide vane, the coefficient of power of the cross-flow wind turbine was increased about 84.3%.

This research aims to identify the role of the stakeholders for Deep Discount Bond (DDB) and Land Lease (LL) joint funding schemes and the institutional success factors, and to determine the most effective institutional model by involving private parties
It means that project finance is still not suitable to be implemented in Indonesia
Summary
The World Economic Forum in its 2016 Global Competitiveness Report revealed that the existence of efficient and growing infrastructure within a country can ensure economic activities in various sectors that can develop that country. Bonds is one of the most popular infrastructure debt finance instruments in developed economies such as the UK and the USA [2]. Other cases showed that the USA leased lands to gain income to fund their transportation infrastructure [3]. The institutional model must be made based on the success factors to ensure DDB and LL schemes are running well. This research aims to identify the role of the stakeholders for DDB and LL joint funding schemes and the institutional success factors, and to determine the most effective institutional model by involving private parties
