Daftar Isi:
- The research was conducted to determine the quality of the waters of the Ciwaka Reservoir, Serang City, Banten, based on the content of chlorophyll-a and the presence of phytoplankton. The relationship between the chlorophyll-a content and the presence of phytoplankton with the physical-chemical parameters of the waters was also being analyzed. Thus the results from the study were used as content for learning media education research. This research was conducted from February-July 2021, in Ciwaka Reservoir, Serang City, Banten. A sampling of water at three stations was carried out using the purposive sampling method. Chlorophyll-a analysis was carried out using spectrophotometric methods. The results of chlorophyll-a analyze in each station ranged from 7,458 g/L – 34,352 g/L. Ciwaka Reservoir is included in the category of waters that are eutrophic (polluted) due to high nutrient levels. The water quality of Ciwaka Reservoir is still in good condition according to the designation of class 2 water quality standards in PP No. 82 of 2001. The content of chlorophyll-a and the presence of phytoplankton (abundance, diversity, and dominance) only has a weakness with the brightness (r = 0.000). Phytoplankton diversity was strongly correlated with temperature (r = 0.994). Phytoplankton dominance was strongly related to DO (r = 0.998) and BOD (r = 0.998).

- Penelitian dilakukan untuk mengetahui kualitas perairan Waduk Ciwaka, Kota Serang Banten berdasarkan kandungan klorofil-a dan keberadaan fitoplankton, mengetahui hubungan kandungan klorofil-a dan keberadaan fitoplankton dengan parameter fisik-kimia perairan serta mengetahui bentuk media pembelajaran yang sesuai untuk menginterpretasikan hasil penelitian terhadap kependidikan. Penelitian ini dilaksanakan dari bulan Februari-Juli tahun 2021 di Waduk Ciwaka, Kota Serang Banten. Pengambilan sampel air pada 3 stasiun dilakukan menggunakan metode purposive sampling. Analisis klorofil-a dilakukan menggunakan metode spektrofotometri. Hasil analisis kandungan klorofil-a pada setiap stasiun berkisar 7,458 ?g/L – 34,352 ?g/L. Waduk Ciwaka termasuk dalam kategori perairan yang mengalami eutrofik (tercemar) karena memiliki kadar unsur hara yang tinggi. Kualitas perairan Waduk Ciwaka masih dalam kondisi yang baik sesuai peruntukan baku mutu air kelas 2 pada PP No.82 tahun 2001. Kandungan klorofil-a dan keberadaan fitoplankton (kelimpahan, keanekaragaman dan dominansi) berhubungan lemah dengan kecerahan (r = 0,000). Keanekaragaman fitoplankton berhubungan sangat kuat dengan suhu (r = 0,994). Dominansi fitoplankton berhubungan sangat kuat dengan DO (r = 0,998) dan BOD (r = 0,998).
