The research on abundance and diversity of phytoplankton has been conducted in the coastal waters of PLTU Holtekamp, Muara Tami district, Jayapura City, Papua Province. The background of this research is environmental was changed and it caused by human activities, PLTU activities, both of derived from organic and inorganic contamination. The purpose of research was to determine the abundance and diversity of phytoplankton in these waters. This research was observation research, namely by taking samples from 3 stations. Sampling was use planktonnet, observe was use microscope, identified, counted, and analyzed plankton diversity index. Identification was carried out at the Zoology Laboratory of the Biology Education Study Program, Department of Mathematics and Science Education, Teacher and Education Faculty, Cenderawasih University. Plankton abundance was calculated using Lackey Drop Micro Transect Counting Method and Plankton diversity was calculated using formulas Shannon-Weaner. The result shows that there were 17 genera of phytoplankton which were dominated by  diatoms and dinoflagellates. The highest abundance found in the station 3 is 2655 ind/l. Diversity index (H') ranged from 1.73 to 1.90 which indicates that there is unstable ecological conditions and dominance index (C) ranging from 0.24 to 0.28 which indicating there no dominant species.

Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ′) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality

Abstract: The purpose of this study was to improve the results and learning process of Genetic subjects in the Biology Education Study Program through lesson study (LS). The research type is descriptive, the sampling technique used purposive. The study sample used 40 students in the sixth semester of class a Biology Education Study Program, Faculty of Education, University of Mataram in academic year 2017/2018. The research data collection technique used observation, documentation, and tests. Data on student learning outcomes and LS-based learning processes were analyzed descriptively. LS implementation in this study consisted of four cycles and each cycle consisted of three stages, namely: planning, implementation, and reflection. Classically the average value of students' cognitive achievement is 82.1% in cycle I and II while in cycle III and IV it increases to 82.67%. Data from LS implementation observation results obtained an average value of 91.63%. The conclusion of this study is the application of LS learning can improve student achievement and learning processes on Genetic subjects in the Biology Education Study Program. It is recommended to other researchers to conduct similar follow-up research in broader research areas, more samples, use more complex research designs, and use more subjects so that more optimal results can be found. Keywords: Lessons Study; learning; genetics; learning achievements; collaborative

Student Learning Styles

The industrial revolution 4.0 in the field of education provides convenience in learning methods and processes. Internet-based technology makes it easier for students to learn independently, quickly in providing feedback, and freely choose material from library sources from anywhere. As a result, student learning styles change along with the development of internet-based technology. In the coursework, students can read and combine various writings from several sources, and in-class when students present assignments of learning materials that have been read so that they are easily understood by other students. Likewise, in completing paper assignments from lecturers, students can read various papers given by many lecturers. This happens because of the students' understanding of the assignments given by the lecturer. The purpose of this study was to identify the learning styles of students of the Biology Education Study Program, STKIP PGRI Sumatera Barat on the development of internet-based technology in the industrial revolution 4.0. This type of research is descriptive and the approach used is quantitative. The results of this study indicate that the learning style of students of the Biology Education Study Program STKIP PGRI Sumatera Barat, Padang, West Sumatra tends to be visual, namely 60.3%. The presence of internet technology and its use in an educational institution is a medium or source of learning that can be utilized by students

Tanjung Luar is coastal water used as a waste disposal area for Fish Landing Based (FLB) activities. However, the condition of the waters with phytoplankton as a bioindicator has never been reporting. This research aims to know Bacillariophyceae in terms of abundance, diversity, and measurement of environmental pollution variables. Methods Sampling at the study location was determined by a systematic random sampling method. Data analysis Bacillariophyceae were determined using formula abundance, diversity index, and dominance index. The index of similarity of species between sample points was determined based on the Bray-Curtis Cluster Analysis. Furthermore, the results showed an abundance of Bacillaryophyceae of 322,000 individuals / L classified as low, the diversity index of Bacillariophyceae of 2.162 classified as moderate, and a dominance index of 0.138 (without dominating species). The results showed that the highest species similarity index was between sample points II and III (57.9%), and the lowest species similarity index between sample points I and II was 23.7%. Water pollution on the waters of PPI Tanjung Luar is classified as moderate pollution level and oligotrophic fertility.

Gastropods plays an important role in the food chain on seagrass ecosystem and its existence are depend on the physical-chemical factors in the seagrass ecosystem. This study aims to determine the density and diversity of gastropods associated in seagrass habitat in Nusi and Gersen coastal waters. The measurement results of some physical-chemical waters variables, are still quite good for the life of gastropods. Species composition of gastropod in Nusi at higher than at the Gersen, but instead of individual density in Gersen more higher than Nusi. Diversity index of gastropods at Nusi station is higher (3,757) than Gersen (3.053), on the contrary the eveness and dominance index are higher at Gersen station than Nusi station. Community similarity index by species is low between the two stations, which indicates that the species of gastropods at both stations is quite different. The influence of human activity and higher utilizatin of gastropods in Nusi has lowered the density of gastropods in seagrass habitat, so it needs awareness efforts on the importance of gastropods and the seagrass habitat for coastal ecosystem.
