Characterization and activation of Natural Zeolite from Ponorogo (ZAP) have been done to improve the quality of zeolite as porous material. Analysis of mineral composition is done using X-Ray Difraction (XRD), Fourier Transform-Infra Red (FTIR) Spectroscopy and metal analysis using Atomic Absorption Spectroscopy (AAS). Characterization of the activated zeolite covered about number of acidic sites, surface area, ratio Si/Al and metal composition (Na, Ca, K and Fe). Activated processes is done using various mineral acid, i.e HCl, HNO3, H2SO4 and HPO4 with each concentration at 1 M and 3 3 hours dipping. The result showed that ZAP has composition Ca-klinoptilolit (43.09 %), gismondin (17.57 %), modernit (4.21 %) and quartz (10.37 %). The most efectif of the acid to activate is HCl and is proved to absorp of Zn in waste water. The effect of chemical activation is increasing the ratio of Si/Al, increasing the surface area and reducing some metal composition.   Keywords: natural zeolite, chemical activation, porous material

Concerning measurements with dynamic pressure sensors, one of the most interesting aspects is the influence of a remoting system interposed between the sensor and the measurement point. This mounting system, once correctly characterized, allows one to use the same sensor for different measurement points, reducing the total number of sensors used. In addition, in all the applications involving high temperatures (e.g. combustion chamber), a remoting system allows the use of cheaper dynamic pressure sensors with lower operating temperature capability. A remoting system for dynamic pressure sensors made up by a remoting duct, between the sensor and the measurement point, followed by a damping duct has been characterized for different tube lengths. Tests were carried out with two kinds of sources: a diaphragm-less shock tube for the first set of tests and an acoustic speaker for the second. Results are here reported and commented.
