Abstract

Ground water has a very close relationship, when in rainwater reaches the surface of the earth, some will enter the ground (infiltration) to be come part of ground water (groundwater) while absorbed by the ground will be come a surface run off (run off). Unima campus area has 270 hectare of land, the exictence of flat to steep topography, various vegetation and land management for campus buildings on unima very much allows different infiltrasions in various locations. This study aims to analyze the infiltration capacity of four fields and compare the infiltration capacity of the four fields using exploratory methods (eksploratory research) this research is also referred to as a very basic eksploratorion study, measurements are carried out using the horton formula and processed in microsoft excel applications. The results showed that the four lands with a lot infiltration capacity of 16,8 cm/hour with medium classifiction. Sloping land less trees infiltration capacity 34,8 cm/hour with a rather fast classification. Flat land many trees infiltration capacity of 14,4 cm/hour the clasification is rather slow. Flat land less trees infiltration capacity is rather slow. Flat land less trees infiltration capacity is 8,4 cm/hour slow classification. Of the four lands can be compared to land that has high infiltration found in sloping locations with less trees and the lowest infiltration on flat land with less trees.

Abstract

The purpose of this study was to determine the effect of teaching aids PBL learning model on student learning outcomes Static Fluid material class XI Science. Researchers used two classes namely, the experimental class numbered 24 students and the control class numbered 24 students. Both classes were given tests so that researchers could know the initial abilities of students, then each treatment was given. The experimental class uses the PBL model assisted with teaching aids, the control class uses the conventional model. After being tested for the second class posttest, it was obtained tcount> t table = 9.077> 2.01174. So, through this study, researchers can conclude the learning outcomes of the Experimental class using the Problem Based Learning model assisted with props larger than the Control class using the Conventional learning model.
