Tujuan dari penelitian ini adalah untuk mengetahui kelimpahan fitoplankton dan zooplankton, mengetahui perbandingan fitoplankton dan zooplankton, dan mengetahui status saprobitas. Penelitian ini menggunakan metode deskriptif yang dilaksanakan pada bulan September 2017 di perairan tambak di Kampung Tambak Lorok Semarang. Sampling dilakukan dengan menggunakan purposive sampling pada 4 stasiun dengan masing-masing stasiun 3 titik. Variabel yang diukur adalah kelimpahan fitoplankton, kelimpahan zooplankton, dan nilai saprobitas. Hasil penelitian menunjukkan kelimpahan fitoplankton berkisar antara 47-154 ind/l dan kelimpahan zooplankton berkisar antara 0-9 ind/l. Perbandingan fitoplankton dan zooplankton berkisar antara 7:1 sampai 47:0. Nilai SI (Saprobik Indeks) berkisar antara 1,28-1,33 dan nilai TSI (Tropik Saprobik Indeks) berkisar antara 1,89-2,50.

Purpose of this research is to know the abundance of phytoplankton and zooplankton, the comparison of phytoplankton and zooplankton as well as the status of saprobity. This research was carried out on September 2017 in the pond waters at Tambak Lorok Semarang Village by using descriptive method. Sampling was applied by using purposive at 4 station, each station using 3 point. Measured variables were phytoplankton abundance, zooplankton abundance, and saprobity value. The results showed that phytoplankton abundance ranged between 47-154 ind/l, while zooplankton abundance betweem 0-9 ind/l. Comparison of phytoplankton and zooplankton ranged from 7:1 to 47:0. The SI (Sabrobik Index) value ranged from 1,28-1,33 and the TSI (Tropic Saprobik Index) value ranged from 1,89-2,50. Based on SI dan TSI values mentioned above the condition of ponds in Tambak Lorok Village is classified as Oligosaprobik or uncured waters to minor contaminated and mostly in β-Mesosaprobik status or mild to moderate contamination. }, issn = {2721-6233}, pages = {237--245} doi = {10.14710/marj.v7i3.22547}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/22547} }
