The purpose of this study is to examine tourist loyalty, which is developed through the value of experience and the image of the destination mediated by the strength of tourist engagement. The research is using a survey with the interview method and distribution of structured questionnaires, related agency documents, research reports, publications, and other literature relevant to research such as data on the number of tourism destinations in South Sumatra. This study examines all tourists who visiting natural tourism destinations in Palembang City, Lahat and Pagar Alam. This study was conducted in one district and two cities in South Sumatra because in these three areas feature natural tourism destinations visited by domestic tourists. The data analysis was carried out by structural equation modeling (SEM) with the help of the AMOS program. This study explains that the value of tourist experience and destination image has a positive and significant effect on the strength of tourist engagement. The value of experience and tourist engagement has a positive and significant effect on tourist loyalty. Destination image does not affect the tourist loyalty. The strength of tourist engagement is mediating the relationship between experience value and destination image, and tourist loyalty.

Power Consumption of Piezo-Composite Actuator at Resonance Frequency
Setiawan, Hery,Yoon, Kwang Joon,Park, Hoon Cheol,Goo, Nam Seo Trans Tech Publications, Ltd. 2006 Key Engineering Materials Vol.306 No.-
<P>This paper addresses the power consumption of the LIPCA (LIghtweight Piezo-Composite Actuator) device system when electric input was applied at its resonance frequency. The LIPCA device system is composed of a piezoelectric ceramic layer and fiber reinforced lightweight composite layers. Typically, a PZT ceramic layer is sandwiched by a top fiber layer with low CTE (coefficient of thermal expansion) and base layers with high CTE. The advantages of the LIPCA design are weight reduction by using the lightweight fiber reinforced plastic layers without compromising the generation of high force and large displacement, and design flexibility by selecting the fiber direction and the size of prepreg layers. An experimental set-up was specially designed to measure the power consumption of the LIPCA. By measuring the capacitance of the PZT ceramic wafer during the test, the electric power that consumed can be determined. Experimental results revealed a significant increase in capacitance of the PZT ceramic wafer with an increase in the frequency of applied voltage around the natural frequency of the actuator. </P>
