Abstract

The purposes of this research are to validate the potential of superior natural resources and human resources in the tourism development of education based on Tri Hita Karana (THK) in Mengesta in Bali, to establish the centers of educational tourism, to form groups of community that supports the educational tourism based on THK, and to design media promotion. The method designed to achieve the targets are analysis, design, evaluation, and revision. Data were collected through observation, questionnaires, and interviews and analyzed using SWOT analysis and descriptive analysis. The results of this research show that there are seven learning resources that have been successfully validated, namely: dance and percussion forum, natural agricultural laboratory, Bali traditional house, agriculture training center, tracking, natural panorama and hot water bathing place, and culinary tour. The understanding and commitment of the people about educational tourism based on THK fall into good categories. Moreover, the media promotion has been successfully designed, which are in the form of art forum brochure, village tourism brochure, and a draft of guide book to educational tourism based on THK.

Abstract

The study of silica from pumice was done by extraction method using NaOH, H2SO4, and HCl. Powder of pumice before extraction was calcined at 450oC for 4 hours. The extraction powder was calcined at 800 °C for 3 hours. The powder before and after the extraction were characterized by XRD and SEM-EDS. Sample also characterized by DTA-TGA analysis before extraction and after extraction was analyzed by TEM. XRD pattern powder of pumice dominated by amorphous silica. The results have been confirmed with SEM-EDS showing that the silica content has the highest percentage, ie 65.88% for the sample before extraction and 78.95% for the sample after extraction. From the TEM observation it shows spherical particles, with particle size of 5.8 ± 0.2 nm. DTA-TGA analysis for pumice powder shows the occurrence of endotherm and exothermic events accompanied by mass shrinkage along with warming temperature rise.
