It is believed that organizational culture is one of the primary strategies that drive employee productivity and competitiveness. The abstract of organizational culture is a complex and dynamic phenomenon and challenge in the field of research till the present. The efficacy of human interaction with an organization is closely related to the propagation of organizational culture. In the meantime, cultural entropy is a metric for assessing the process of cultural dissemination in organizations, where a reduced entropy value is preferable. This study aims to modify the entropy culture algorithms that accommodate discrete and continuous vectors. We applied Shanon’s entropy as the fundamental formulation and the Axelrod model as the peer interaction analysis. The proposed measurement of cultural entropy considers not only the desired values but also evaluates the gap with the espoused value of the organization. The modified cultural entropy algorithm can measure the entropy value for discrete and continuous vectors. Measuring cultural entropy using continuous data results in an approach that can better display value heterogeneity within organizations.

Based on Google Trends, searches related to cryptocurrency have significantly increased in the last couple of years. One crucial aid for cryptocurrency traders or investors is the graphical visualization, which shows the time series data of the cryptocurrency prices. However, problems may occur in data visualization, such as visual noise and information loss, which cause perceptual and cognitive errors in data reading. Therefore, good visualization is needed to avoid decision-making mistakes, particularly in the cryptocurrency trade and investment activities. This study aims to investigate the effect of chart design and time interval on the usability of data visualization. The experiments are conducted in two scenarios, i.e., with and without time pressure. The participants recruited in this study were non-experienced and experienced people classified based on their familiarity with cryptocurrency investment/trading. Objective usability testing is performed by eye tracking, while subjective assessment employs the System Usability Scale (SUS) questionnaire. There are four quantitative dependent variables: response time, number of errors, number of fixations, and time to first fixation. The results show that time interval and time pressure significantly affect usability for both groups of respondents. Although chart design does not substantially affect the dependent variables, a candle chart is generally better than a line chart. By comparing all the combinations of chart design and time intervals, this study concluded that combining candle charts with 1-hour or 4-hour time intervals gives the best results for both respondent groups.

The study discusses teachers’ knowledge and experience using learning media for elementary schools’ forest and land fire disaster mitigation. The results of this study are used as a preliminary investigation to design an Air Pollution Index Simulator (SI-ISPU). The research method used is a survey method. Respondents in this study amounted to 23 teachers in elementary schools. Data collection techniques using closed questionnaire techniques and data analysis techniques using descriptive statistics. The results showed that 39.13% of teachers still did not know the learning media that could be used to teach forest and land fire disaster mitigation. Then, 69.57% there are still many teachers who have not taught using learning media for forest and land fire disaster mitigation. The experience of teachers who have developed learning media for forest and land fire disaster mitigation is only 13.04%. Then 78.26% of teachers experienced problems developing learning media for forest and land fire disaster mitigation. Furthermore, 65.22% of teachers have difficulty teaching forest and land fire disaster mitigation. The research concludes that most teachers still experience difficulties and obstacles in developing learning media and teaching about forest and land fire mitigation in elementary schools.
