Abstract

Site selection is influenced by several factors like the volume of material to be deposited, whether or not coal seams underneath, distance and topography. The amount of material that must be stockpiled on site Disposal Dumping Material (heap) the longer the sums are increasing, This goes along with the progress of mining.Considering the increasing number of opening new mines in PT. Bukit Asam (Persero), Tbk, so that the soil exposition needs to be managed properly. Required to standardize the management of the soil pile, so the pile area can be used optimally.From the direct she ar strength test results data showed parameter are cohesion ( C ) = 36.24 kPa,  friction angle (f)  = 16.72˚, and wet density (gw) = 19.36 kN/m3Based on simulation results F Kon a pile Banko Barat Pit-1 Timur derived the optimization of simulation (Geostudio/ Slope W 2007) sho thatby adding 7 ladder more with 6 meter high slope, angle ofa single slope 1: 2 and 25 meter of wide berm is still safe.

Abstract

This research is motivated by the teacher who only explains the material to be practiced verbally, and the series of pictures that will be practiced are illustrated by the teacher on the board, and the teacher directly instructs students to do the practice. This makes it difficult for students to understand and analyze the working principles of the control system, and so far students are only able to assemble and operate the circuit but students have not been able to explain how the circuit can operate. Therefore we need learning media that can support this, one of them is by applying Festo Fluidsim simulation learning media. This type of research is a descriptive study with quasi-experimental methods with the design of One Group Post-test Only. From the results of the study obtained an average post-test score of 76.63. With the t test analysis obtained t count = 2.754 which is greater than the table = 2.492 at the 0.01 significance level. Thus it can be concluded that there is an increase in student learning outcomes after the application of simulation software in the learning process of MSPEM class XI TITL SMKN1 Tilatang kamang.
