HYBRID OPTIMIZATION METHOD BASED ON GENETIC ALGORITHM FOR GRADUATES STUDENTS

Graduation is a target that must be achieved by students, especially graduating on time will be very important. To determine students who graduate on time or cannot be determined before students reach the final semester and hold a trial, many students who fail to graduate on time cause delays and affect the quality assurance of a tertiary institution. The problem in this research is how to optimize student graduation in order to graduate on time. Therefore, to determine this decision, we conducted a graduation data trial using the SVM method with GA optimization. SVM with accurate learning skills and good generalizations in classifying non-linear data, but SVM is weak in terms of parameter optimization it requires optimization using GA. GA is a method that has evolved to produce a more optimal data. From the results of processing using SVM and GA, we get more optimal results with 86.57%. Then from these results can help students to graduate on time

Perceived workload and organizational citizenship behavior (OCB): The role of psychological empowerment

Organizational Citizenship Behavior (OCB) refers to employee behavior that is voluntary and does not attract formal rewards from organizations, but which can increase their effectiveness and efficiency. This study aims to examine the mediating effect of psychological empowerment on the relationship between perceived workload and OCB. Data were collected using the snowball sampling method and an online survey of 201 employees aged 19-50 working in various private organizations in Indonesia, particularly in the Jakarta, Indonesia (female: 54.7%; male: 45.7%). The measuring instruments used were the workload subscale of the Job Demand-Resource scale, the Psychological Empowerment Questionnaire (PEQ), and the OCB subscale of the Task Performance Scale. Data were analyzed by the mediation technique using Hayes's Macro. The results show that perceived workload positively predicted psychological empowerment (B = 0.192, p .01) and that psychological empowerment positively predicted OCB (B = 0.2189, p .01). The results also show that psychological empowerment mediated the relationship between perceived workload and OCB (B= 0.021, SE = 0.0160, 95% CI [0.0143, 0.0759]). From the findings, it is expected that organizations will be able to manage the workload of their employees and create positive emotions in it

EFL LEARNERS' EXPERIENCES OF PEER FEEDBACK IN PARAGRAPH WRITING THROUGH CLOUD COLLABORATION

ABSTRACTOnline peer feedback has become common in university writing classrooms due to the availability of computer technology. This study aimed to explore EFL learners' experiences engaged in online peer feedback on writing through cloud collaboration. This study was an extension activity of the paragraph writing class for two weeks, in which ten participants voluntarily took part in it and were monitored by two instructors.
