Reducing the energy consumption of industrial robots (IR) that are used in manufacturing systems has become a main focus in the development of green production systems. This is due to the reality that almost all automated manufacturing processes are using IR as the main component. Thus, reducing the energy consumption of IR will automatically reduce operating costs and CO 2 emissions. Therefore, a method for reducing the energy consumption of IR in manufacturing systems is desired. Firstly, this paper presents a literature survey of the research in energy consumption analysis of IR that is used in manufacturing processes. The survey found that current research in this field is focused on the development of simulation models of IR that are able to be used to predict its energy consumption. Secondly, a modular model to analyze power consumption and dynamic behavior of IR is developed. Afterward, an experimental investigation is carried out to validate and estimate the accuracy of the model developed. The investigation shows that the developed modular model can be conveniently used to optimize the industrial robot's operating parameters, which are commonly needed for production planning and at the process optimization stage. In addition, the investigation shows that the process constraints, environment layout, productivity requirement, Paryanto ( ) · M. Brossog · J. Franke as well as the robot payload and operating speed are the key factors that must be considered for optimizing the productivity and efficiency of IR.

The purpose of this study was to study the application of working culture to the learning practice of machining in vocational high school (VHS) Muhammadiyah 1 Salam. The industrial working culture adds value to integrity, professional, productive, innovative, and competitive. This research is a quantitative and qualitative descriptive study. The subjects in this study were machining subject teachers of class XI and XI grade students in mechanical engineering majors at VHS Muhammadiyah 1 Salam. The obtained data were analyzed through descriptive analysis. The results show the value of integrity that has been implemented by 88% of students by behaving honestly and responsibly. Professional values have been applied to 54.8% of students with standardized procedures and applying K3 while working. Productive value has been applied 69% of students according to the time and quality determined. 27 % of students have applied innovative value. Innovative value is applied by finding new alternatives at work. Competitive value has been applied by 53% of students by looking for information related to the field of work and confidence in showing competence.
