Film Unyil puppet comes not just part of the entertainment world that can be enjoyed by people from the side of the story, music, and dialogue. However, there is more value in it which is a manifestation of the creator that can be absorbed into the charge for the benefit of educating the children of Indonesia to the public at large. The Unyil puppet created by the father of Drs. Suyadi is one of the works that are now widely known by the whole people of Indonesia. The process of creating a puppet Unyil done with simple materials and formation of character especially adapted to the realities of the existing rural region. Through this process, this research leads to the design process is fundamentally educational puppet inspired by the creation of Si Unyil puppet. The difference is the inspiring character created in this study is on the characters that exist in urban life, especially the city of Jakarta. Thus the results of this study are the pattern of how to shape the design of products through the creation of the puppet with the approach of urban culture.

<p>A vertical axis wind turbine triple-stage savonius type has been created by using simple materials to generate electricity for the alternative wind power plant. The objective of this research is to design a simple wind turbine which can operate with low wind speed. The turbine was designed by making three savonius rotors and then varied the structure of angle on the three rotors, 0˚, 90˚ and 120˚. The dimension of the three rotors are created equal with each rotor diameter 35 cm and each rotor height 19 cm. The turbine was tested by using blower as the wind sources. Through the measurements obtained the comparisons of output power, rotation of turbine, and the level of efficiency generated by the three variations. The result showed that the turbine with angle of 120˚ operate most optimally because it is able to produce the highest output power and highest rotation of turbine which is 0.346 Watt and 222.7 RPM. </p><p><strong>Keywords</strong>: Output power; savonius turbine; triple-stage; the structure of angle</p>

Variational Formulations

For homogeneous higher-gradient elasticity models we discuss frame-indifference and isotropy requirements. To this end, we introduce the notions of local versus global SO(3)-invariance and identify frame-indifference (traditionally) with global left SO(3)-invariance and isotropy with global right SO(3)-invariance. For specific restricted representations, the energy may also be local left SO(3)-invariant as well as local right SO(3)-invariant. Then we turn to linear models and consider a consequence of frame-indifference together with isotropy in nonlinear elasticity and apply this joint invariance condition to some specific linear models. The interesting point is the appearance of finite rotations in transformations of a geometrically linear model. It is shown that when starting with a linear model defined already in the infinitesimal symmetric strain [Formula: see text], the new invariance condition is equivalent to the isotropy of the linear formulation. Therefore, it may also be used in higher-gradient elasticity models for a simple check of isotropy and for extensions to anisotropy. In this respect we consider in more detail variational formulations of the linear indeterminate couple-stress model, a new variant of it with symmetric force stresses and general linear gradient elasticity.
