PENGARUH PENGAWASAN PIMPINAN TERHADAP DISIPLIN KERJA KARYAWAN PADA PABRIK MESIN INDUSTRI KECAMATAN GEGER KABUPATEN MADIUN

This study aims to determine Supervision Leadership in Plant Engineering Industry, to know Discipline Employees in Industry Machinery Factory, as well as to determine whether or not Influence Between Monitoring Employee Discipline Leader Against the Machine Factory Geger Madiun County Industrial District. This research uses design conclusive studies. Data collection using questionnaires, observation, documentation and data analysis using linear regression correlation test, F test and t test. The results showed that the supervisory leaders have influence at the same time a positive relationship to discipline employees working at Plant Engineering Geger Madiun County Industrial District. It can be seen from the results of linear regression analysis of Y = 11.277 + 0.840 X. This means that if the leadership supervision increased by 1%, the discipline of employees will increase by 0.840% if other factors held constant. Based on the hypothesis testing results obtained from the correlation test showed that rhitung is 0.6727 while the value rtabel at N = 30 is 0.361. Thus H0 is rejected, meaning that there is difference between the effect of supervision led to the discipline of employees at Plant Engineering Geger Madiun County Industrial District.

Study on Natural Lighting Modification of Existing Steel-Structure Plants in Cold Regions

This thesis takes it as an example that the steel-structure processing workshop of a machinery factory in Shandong province of cold areas, makes use of the software to simulate the factory’s natural lighting environment according to real conditions and objective analysis to its simulation result. Besides, it proposes feasible measures of optimizing and modifying lighting windows area and material selection for the purpose that creating a comfortable lighting environment for the steel-structure industrial plants in cold areas, and it also plays a role in rendering effective suggestions and reference.

The Theoretical Analysis and Application of the Ultra-Precision Machining the End Surface of Stop Valve’s Valve Flap with the Diamond Facing Tool

A new process was proposed. The disadvantage of of using brown alumina grinding wheel to grinding and lapping surface was studied in the analysis. The diamond facing tool was designed and manufactured with the solution of the key technique of the critical technical of single crystal diamond’s material selecting, grinding, welding. The face cutting parameters: “V”, “f” and “ap” were measured by experiment and academic analysis. Tt can fully meet the quality requirements of stainless steel valve flap’s surface used by one valve machinery factory; meanwhile the productivity was increased by a factor of 15, with overcoming the disadvatange of grinding and lapping valve flap’s surface.
