Abstract

The article aims to analyze the perception of professional skills acquired in online learning among electronic engineering students. The research method is qualitative, with a descriptive approach, since it focuses on analyzing the statistics of the students' perception (frequency of satisfaction levels). Initially, the reliability of the instrument was determined using Cronbach's Alpha, obtaining a consistency coefficient of 0.967 and 0.932, in the academic semesters 2020-I and 2020-II, respectively. The data collected by means of a virtual questionnaire were processed in the SPSS software transformed into the Likert scale. The results obtained show a high perception among electronic engineering students in reference to the professional skills they have acquired. There is an increase in satisfaction from 66.78% (2020-I) to 74.26% (2020-II) between the first and second academic semester, despite the abrupt and unexpected change in the teaching-learning modality, in the second semester achieved a greater adaptation of this process. However, the online learning method should continue to be improved so that students perceive with greater satisfaction that they possess the skills to solve problems and cases related to the specialty) and the skills to master practical professional skills.

Abstract

This article describes the design of an automated system for the automatic monitoring and control of the liquid wax production process, in order to quantify its effect on productivity indicators. For which initially the procedure for obtaining the automation will be described; then the results obtained will be presented, the same ones that will be identified through a comparative analysis. During the investigation it was determined that, through the use of a programmable logic controller, it was possible to improve the precision of the dosage of components in the liquid wax production process; By achieving acorrect dosage, it is achieved that the physical-chemical factors that intervene in the quality of the final product, which are the pH and specific density, are within the limits established by the company, this is reflected in the decrease 38.77% of the amount of monthly loss of raw material, thus achieving the optimization of the productivity of the production of liquid wax by 83.69% per month, compared to the non-automated process.
