Abstract

This study was conducted based on the findings of radioactive minerals in the form of indication of relatively high radiation dose rate anomalies. The hypothesis underlying the existence of a high radiation dose rate is the deposition of uranium derived from basalt rock Auwea Formation, uranium enrichment derived from limestone to the soil surface, and the deposition of uranium resulted from the use of fertilizers in agriculture. Therefore the research aimed to obtain the conclusion of its hypotheses. Research methodology applied is geological mapping, radiometric measurement of uranium (U), thorium (Th), and potassium(K) in the field using RS 125 to determine in-situ grade of elements, radiometric measurements of plant fertilizer, sampling, and laboratory analysis of the element grade. Based on the analysis and evaluation of survey data it is known that in the area around Maryendi, Darmapis and Denafi, indicate the presence of anomalous zones which is characterized by the presence of uranium (U) dark brown soil – reddish brown, with the value of the radiation dose of 1.9 to 4,032.3 nSv/h and grade of uranium (U)has 20.27 to 325 ppm eU. Based on the analysis of source rock of uranium, it is concluded that limestone is the source rock of uranium in research area. The results of field observations of the fertilizer and basalt rock of Auwea Formation, it is found that no anomalies may indicate material/rock that acts as the source of uranium.

Abstract

This research aims to describe the form and creative process of creating the Tari Kleting Sumandhing. The method used in this study is descriptive qualitative research through observational data collection, interviews, and literature studies. The result of this research is the form of the Sumandhing Kleting Dance which consists of movement, dancers, makeup, and clothing, floor patterns, accompaniment music and staging venues. So that the dance form finds beautiful choreography and can be felt by the five senses. Meanwhile, the creative process is the process of thinking in creating, expressing, and creating the visuals of the Tari Kleting Sumandhing. This creative process involves deep exploration to translate values into symbolic forms of movement. The visualization of this symbol is expressed by thinking creatively as a process of imagining combining feelings and movements to find the expression of the character or figure of Kleting Kuning.
