Published: December 2019

The high unemployment rate of vocational high school graduates, which is up to 9.27% of the 131.55 million productive age people, is the result of the weak evaluation of the learning process. This can happen because the learning system is still focused only on hard skills teaching (skills evaluation), and ignores evaluations related to soft skills, especially those that include evaluation of 4C (Creativity, Critical Thinking, Communication, and Collaboration). In this 4.0 revolutionary era with the digital-based work character, the government sought to improve the quality of vocational high school graduates by launching a policy on revitalizing vocational education. Currently, the quality of learning evaluation instruments in vocational high schools is still considered less valid so that it has not been able to evaluate aspects that are fully evaluated. Referring to eight national education standards, one of which is related to evaluation standards, it seems that there have not been many studies specifically and comprehensively, especially related to the 4C evaluation model. The purpose of this study is to develop a 4C evaluation management model in the productive learning of vocational high schools which the results can help succeeding the vocational high schools revitalization program. This study used the Research and Development (R & D) approach and for testing the effectiveness of the model, it used the project learning strategy (PjBL), which also used to produce a product that is a 4C evaluation management model. A test-shaped evaluationis used to measure cognitive domains (knowledge), while non-test to evaluate performance (performance test) is usedto measure affective domains (attitudes) and psychomotor (skills).

Natural Animal Sound Spectrum Characterization based on Fourier analysis is a undamental scientific study of the spectrum of natural animal sounds that can be used as a stimulator of growth and productivity in food intensification. The results of characterization are very useful for adding scientific treasures in the field of biophysics, especially to support the use of natural animal sounds as stimulators of growth and productivity of food crops through spectrum analysis based on Fourier analysis so that it has a strong theoretical basis to be developed into an applied industry in the field of food intensification. Natural animal sound spectrum is obtained by recording animal sounds naturally in nature by using a voice recorder. Furthermore, the sound of these natural animals analyzed their spectrum characteristics using Adobe Audition to determine the peak frequency produced. Sound spectrum characterization which has peak frequency sonic bloom between 3000Hz - 5000 Hz is made as an audio stimulator for growth and productivity of food crops. From various 27 sources of animal sounds recorded and analyzed, there are 17 types of animals that have frequency peaks in range sonic blooms (3000-5000 Hz) and can be produced into stimulators and 1 combined stimulator. While the results of the sound timbre analysis of each animal has a frequency range including: 1-1000 Hz a number of 6 animals, 1000-2000 Hz of 8 animals, 2000-3000 Hz a number of 14 animals, 3000-4000 Hz a number of 12 animals, 4000-5000 Hz is 2 animals, and 5000-6000 Hz is 4 animals.

Published: December 2019

The use of a reference manager (RefWorks, Mendeley, EndNote, Zotero) has become very important in the writing of scientific papers for students and lecturers. The Faculty of Economics of Semarang State University (FE UNNES) has called on students to use a reference manager when composing a thesis. This study aims to analyze factors that influence the utilization of reference managers by FE UNNES students. The theories used are the Unified Theory of Acceptance and Use of Technology (UTAUT) and the Theory of Planned Behavior (TPB). The research population was students working on their theses at FE UNNES. The data collection method used is a questionnaire distributed online to respondents through the Google platform. The data analysis method used is path analysis. The results show that performance expectancy and social influence have positive and significant effects on a student’s intention to use a reference manager. Meanwhile, effort expectancy is not proven to have a significant effect on a student’s intention to use a reference manager. Effort expectancy, performance expectancy, and social influence have a significant effect on the use of reference managers. Other results show that behavioral intention, lecturer guidance, and policy pressure do not significantly influence the use of reference managers. The results of this study demonstrate that the use of reference managers by students is more influenced by perceptions of their usefulness. That is, students assume that the use of a reference manager is a necessity.
