Abstract

AbstractThe problem in this research is "How to influence  discovery on learning outcomes of IPA student grade V Primary School?". This research aims to analyze the influence of  discovery on the outcome of science students grade V Primary School.This study used experimental methods, with the form of quasi Experimental Design. The population in this study is all students of grade V Primary Schoolwhich amounted to 64 people. The sample in this study was a VA class student numbering 32 people. The data collection technique used in this research is a measurement technique with the tools used is a double choice written test as much as 45 questions. Based on data analysis obtained average final test result student of experimental class of 75,03 and average final test result of control class students of 70,53. After conducted test T acquired Tcount of 1,7108 whereas Ttable of 1,6706 it turns out Tcount ≥ ttable or 1.7108 ≥ 1.6706 which means there is influence of  discovery of learning results of IPA students in grade V Primary School. From the effect of calculation result is obtained by 0.38 with the criteria classified as medium. This means the application of discovery learning gives a moderate influence on the outcome of learning IPA students grade V Primary School. Keyword: Influence, Model of Discovery, learning outcomes, natural sciences.

Abstract

Clinker is an artificial rock produced from kiln feed or rawmeal through a process that occurs in a rotary kiln with a temperature of around 1450°C. In the heating process in the rotary kiln, physical reactions and chemical reactions occur simultaneously. The methodology used to complete this article consists of several stages including the following: Taking actual condition data from the Central Control Room (CCR) and composition data from the Quality Control (QC) laboratory. From the results of the performance evaluation, the thermal efficiency of the rotary kiln is still classified as good with an average of 74.05% where the good efficiency ranges from 71%-84%. This value indicates that the performance of the rotary kiln is still fairly good when viewed from the actual calculated thermal efficiency. Regular checking, maintenance and repair is an increase in the performance of rotary kiln equipment so that the obstacles experienced can be reduced. he decrease and increase in AFR value is also influenced by the size of the feed flow rate that enters the combustion process.
