Abstract

This represents an advanced Research and Development (R&D) study designed to evaluate the practicality and effectiveness of an e-encyclopedia which has been built and validated with very valid results. The fourteen students who formed up the research subjects. Pre-test and post-test questionnaires, observation sheets, and student response questionnaires were used as the study instruments. The study data analysis technique was descriptive quantitative through three stages, namely calculating the percentage value of practicality and effectiveness tests, Mann-Whitney U non-parametric test, and N-Gain (g) test. An average percentage value of 85.63% was attained with a very practical category in the practicality test analysis findings. With a percentage score of 81.13%, the effectiveness test analysis revealed a very strong response from the students. In contrast, there was a significant difference between the pre-test and post-test findings in terms of raising CTS by 0.78 with a high category, according to the effectiveness test analysis results using the Mann-Whitney U test and the N-Gain (g) test. The conclusion shows that Canvaflipedia to improve CTS is proven to be practical and effective, so it is suitable for use.

Abstract

So far, cognitive style-based critical thinking, collaborative, and communication skills have yet to be utilized optimally. Additionally, there has been no research on optimizing 21st-century skills in cognitive style through the implementation of Figma Contextual Teaching Learning Learning Media (Figma-CTLLM). The research aims to optimize critical thinking, communication, and collaboration skills based on reflective and impulsive cognitive styles by implementing Figma-CTLLM in Poaceae diversity learning. The type of research is quantitative descriptive research. The research subjects consisted of 26 students. Research instruments include MFFT sheets, critical thinking and communication skills in written form test sheets, and collaboration skills observation sheets, all of which had been validated and proven reliable for use. The data analysis technique was carried out descriptively and quantitatively in three stages. The research results showed that eight students had a reflective cognitive style, and eight had an impulsive one. The results of the analysis of each skill show that there is no significant difference in critical thinking, communication, and collaboration skill scores between students with a reflective and impulsive cognitive style. This is proven by the average percentage value for each skill in the same category, which is very high among students with a reflective cognitive style and impulsiveness. This was also confirmed by the Mann-Whitney U test for each skill with a significance value (p) above 0.05 (p>0.05). Based on the results, the implementation of figma-CTLLM can optimize critical thinking, communication, and collaboration skills in students with reflective and impulsive cognitive styles in Poaceae diversity learning.

Abstract

Background: The need for e-encyclopedia development due to the low utilization of ICT in developing e-encyclopedias makes students lazy and less interested in studying the morphological diversity of Pteridophyta based on local potential. Therefore, the development of Canvaflipedia addresses the above problems as a learning medium that is more interactive and easily accessible to students, and can be applied in the PBL model of learning. This study aims to design and test the validity of an electronic encyclopedia related to the morphological diversity of Pteridophyta based on local potential in PBL learning. Methods: The type of research used is an R&D study with a 4D (Define, Design, Develop, and Disseminate) model, but the research only reached the development stage, which focused on validity testing by three validators using a validation sheet as a research instrument. Data was collected by compiling the results of the validation sheet and analyzed descriptively and quantitatively to interpret the validity results obtained. Results: The findings of the material expert validation test analysis showed a very valid category with an average value of 91.11%. By contrast, the results of the media expert validation test analysis showed a very valid category with an average value of 87.70%. Conclusions: Based on these results, the Canvaflipedia developed is very valid for application in PBL learning.

Abstract

This study aims to determine the diversity index and the importance value index of herbaceous plants found around the Joko Tarub Forest Tuban. The type of research is quantitative descriptive with a sampling method using the quadrat technique. The quadrates were made with a size of 1 x 1 m as many as 10, as a measurement area. The data collection technique was carried out by recording the names of plants and their numbers found in each quadrat. In addition, the area covered by each plant in the quadrat was also calculated. The data analysis was carried out by calculating the density of species, dominance, and frequency as a basis for calculating the important value index. In addition, the Shannon-Wienner diversity index was also calculated to determine the level of diversity of herbaceous plants living in the area. From the results of this study, 10 types of herbaceous plants were found which are included in 9 Families. Of the 10 types of plants found, those with a high importance value index are Synedrella nodiflora and Crassocephalum crepidioides with values ​​of 53.61 and 44.37 respectively. The herbaceous plant diversity index in the region is in the moderate with a value of 1.89
