Abstract

Noemuti River is a river located in North Central Timor District. The river is used by local people for daily needs such as washing motorbikes and clothes. In addition, at some point it is also used to mine sand. Seeing this phenomenon, it is estimated that there has been a change in the plankton community in the river, so it is necessary to conduct research on the plankton community in the river. This research was conducted by purposive random sampling to take existing plankton samples to see their abundance, diversity, dominance and evenness using index calculations. Based on research that has been done, the Noemuti River has an abundance of plankton 11400, 8716 and 7241 cells/L. The diversity index is 2.362; 2,627; and 2,880. Dominance index 0.173; 0.121 and 0.071 and the evenness index is 0.753; 0.838 and 0.918 this shows that the Noemuti River has a moderate and relatively even distribution of plankton diversity. So it can be concluded, that activities around the Noemuti river do not really affect the existing plankton community.

Abstract

This research aims to design an Angiosperm plant catalog application as an effort to provide learning media to support biology learning in recognizing Angiosperm plants. This study uses a 3D development model, namely define, design, and development. The define stage is carried out using the field needs survey method. The design stage is carried out by designing an Angiosperm plant catalog application. The develop stage is carried out with validation tests and application usage tests. Application design is carried out by creating activity diagrams, interface designs, and designs using Android Studio. The final stage of application design is checking navigation, performance, and operations. The application is validated by material experts and media experts, and tested for use by peer reviewers, teachers, and students. The average results of the angiosperm plant catalog application product assessment were 86.36% with very good quality by 2 material experts, 85.7% with very good quality by 2 media experts, 95.14% with very good quality by 10 peer reviewers, 90.76% with very good quality by 2 biology teachers, and 85.2% with very good quality by 25 students of MAN 2 Yogyakarta.
