Abstract

Bryophytes is one of the various plant groups that have an important role in biodiversity. Bryophytes have an essential role in environmental ecology, including mosses contributing to the nutrient and water cycle and the carbon exchange cycle. This research aims to determine the effect of waterfall distance on bryophyte diversity in the waterfall area. This research uses an exploratory descriptive method with data collection locations at Coban Rondo Waterfall, Pujon District, Malang Regency. The research was carried out by collecting data directly in the field by observing and exploring according to the conditions at the research location. The objects in this research are classes bryophytes that grow around the waterfall area by creating three plots measuring 5m x 5m with the installation at the wet zone which is located in the waterfall area <25 m, the humid zone which is 25-50 meters from the waterfall, and the dry zone which is more than >50 meters from the waterfall. Each bryophyte found in a single plot in three zones will be analyzed by considering the factors of temperature, humidity, light intensity, and soil pH. The results of the study showed that there was an influence of waterfall distance on bryophyte diversity. The closer the location where bryophytes grow to a waterfall, the more diverse the number of species.

Abstract

This research is based on the limited use of learning media which results in students experiencing difficulties in understanding lessons and a lack of learning motivation, which impacts low learning outcomes. This research aims to develop valid, effective, and practical google sites multimedia to improve conceptual understanding and student motivation in the material of the digestive system. The research method used was research and development (RD) with the ADDIE model, namely: analyze, design, development, implementation, evaluation. Data were collected through observation, interviews, and questionnaires. Validation by material experts showed a "very valid" category with a percentage of 87.74%, while media experts reached 90.22%. The effectiveness test produced a significance of 0.000 (0.05), indicating a significant difference between the pretest (63.28) and posttest (89.62) scores, with an average increase in N-Gain of 0.72 (high). The learning motivation questionnaire obtained a score of 88.77% (very high). The practicality test by teachers produced 99.10% and and user responses from students 92.07%, indicating this application is very practical. The research results prove that google sites is feasible, effective, and practical to use to improve students' conceptual understanding and motivation in the digestive system topic
