Abstract

The weed is a plant that develops in undesirable areas and harms surrounding plants. Nonetheless, this herb can be used as a source of organic material, as a soil coating to prevent erosion, and as a traditional medicine. Weed growth can vary depending on the weed’s characteristics and environmental conditions. The Selo region is a verdant tourist destination in the montane zone's highlands. The land clearing caused a change in the area's vegetation. This study seeks to determine the Montane zone's weed vegetation varieties, composition, and structure. It is also connected to the release of land in Selo as a tourist area. This form of research is conducted at three different altitudes (1.600m asl, 1.700m asl, dan 1.800m asl). The intercept-point and exploration method is used, as well as data analysis involving the determination of summed dominance ratio (SDR) values and diversity index analysis. Consequently, there are variations in the composition and dominance of herbaceous vegetation at each height. There are 27 species of vegetation, with Imperata cylindrica (SDR 55.67% and 27.73% at 1.600m asl and 1.800m asl, respectively) dominating at 1.600m asl and 1.800m asl, and Ageratina riparia (SDR 20.86%) dominating at 1.700m asl. The highest diversity of grass species at the altitude of 1.800 m asl (H' 2,17). The highest sorensen’s similarity index is at altitudes of 1.600 m asl and 1.700 m asl (SSI 52,17%). The ecosystem conditions influenced by abiotic factors and the management of ecosystems impact the diversity and uniformity of grass species in the mountainous region of the Selo Tourist Area.

Abstract

This study aims to investigate the effectiveness of using biotechnology e-modules for eco-enzyme production, based on the SETS (Science, Environment, Technology, and Society) approach, on the problem-solving skills of ninth-grade junior high school students. A quasi-experimental design with a non-equivalent control group was employed. The sample consisted of two classes, each comprising 32 students, divided into an experimental class and a control class. The main instrument was a problem-solving skills test based on Polya’s indicator. Data were analyzed using ANCOVA after confirming the assumptions of normality and homogeneity of variance. The results revealed a significant difference between the average posttest scores of the experimental class (80.562) and the control class (46.094), with a significance level of 0.000 (p 0.05). The R² value of 0.952 indicates a powerful influence of the e-module on the improvement of problem-solving skills. This e-module facilitates students’ contextual understanding of biotechnology concepts through the eco-enzyme production project, thereby supporting the development of 21st-century skills. The study recommends the use of SETS-based e-modules as a contextual, innovative, and applicable alternative to traditional learning in science education.
