Two Samples

In this work, autotrophic growth of mesophilic acidophiles from the Underground Copper Mine Bor was performed. Two selected solution samples collected from the 'Tilva Ros' ore body were prepared in a 9K nutrient medium (Silverman and Lundgren, 1959). The first sample TR k-16 was obtained during the hole drilling of the ore body, and the second TR k-31 from the drainage channel. Two samples of 9K media (Silverman and Lundgren, 1959) were inoculated with two selected solution samples from the underground mine Tilva Ros. Inoculated culture media were incubated without prior autoclaving in the period of 6 days at a temperature of 28 ?C with purging air through the system with enough oxygen and carbon dioxide. Oxidation rate of ferrous ions in the first 3 days of incubation was 14.8 and 10.7 wt.% Fe2+/day, the next 3 days 17.3 and 13.6 and for the total period of 6 days 98.3 and 74.8 wt.% for the first and second sample, respectively, i.e. 100 wt.% with initial percentage of ferrous ion in each medium. After centrifugation of enriched samples of culture media at 3000 rpm for 5 min, a plenty of mesophilic acidophiles were determined by microscopic method. According to Karavaiko [6], in the processes of incubition for 9K nutrient solution cells number reach a value of 108 cells/cm3.

This research developed Science, Environment, Technology, Society (SETS) e-module integrated with predict, observe, explain (POE) model on the subject matter of Earth Layer and Its Dynamics for grade VII students. This study aimed to reveal i) the feasibility of the developed e-module for grade VII students, and ii) the practicality of the developed e-module and its dynamics. This is a developmental research adopting the ADDIE model consisting of five stages, i.e.: analysis, design, development, implementation, and evaluation. The subject of the limited test consisted of 15 students of grade VIII.G of Public Junior High School 8 Yogyakarta. The data were collected using a product feasibility assessment sheet for material and media experts, a product practicality assessment sheet for teachers, and a product readability assessment sheet for students. The results show that the developed e-module was feasible to be used according to the material and media experts and the developed e-module is practical according to teachers and students.
