Abstract

Critical thinking is a 21st-century skill that is crucial for problem-solving and decision-making. However, the learning process in schools is still not optimal in developing this skill. This study aims to test the validity of an e-module product developed to improve critical thinking skills. This research is a developmental study using the 4D model. The instrument used was an expert validation sheet. Data collection was carried out through a questionnaire in the form of a validation sheet given to the validators. Data were analyzed quantitatively based on the validation results, then elaborated with qualitative analysis. The results showed that the material validity value from the three validators was 88.47%, language validity was 89.33%, and media validity was 87.33%. These three results were then averaged, resulting in an overall validity value of 88.37%, which is categorized as valid. Input from the three validators was used as a reference for improving the e-module. Thus, it can be concluded that the e-module on the human respiratory system based on problem-based learning to improve critical thinking skills is valid and worthy of being tested.

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
