Environmental chất lượng cultivation of considerable influence against the survival & growth of living beings in the water. Improvements to the environmental conditions of cultivation in order lớn remain stable & optimal for aquatic organisms, including fish as aquaculture animals become very necessary one, namely the granting of Ca(OH)2 (calcium hydroxide) & NaHCO3 (sodium bicarbonate). The application of Ca(OH)2 & NaHCO3 in fish farming serves as the buffer pH of pond water. In addition, the application of both these materials also function as degradation organic matter chemically, control the ratio N/P và the abundance of plankton in the water. This research aims to lớn know the dynamics of the pH value, COD, N/P ratio và abundance of plankton by administering calcium hydroxide (Ca(OH)2) and sodium bicarbonate (NaHCO3) in the water. Methodology this research uses descriptive survey method or a method of research that aimed to lớn describe existing phenomena, which takes place at the moment or the past. The results of the measurement of the pH value before the grant of Ca(OH)2 and NaHCO3 that is of 6.6-6.8 whereas after the grant of Ca(OH)2 và NaHCO3, there is increased và decreased range between 6.8-7.4. The results of the measurement of the value of COD prior khổng lồ the grant of Ca(OH)2 and NaHCO3 that is ranged between 72.5-32.5 mg/l while the after grant of Ca(OH)2 và NaHCO3, there is increased & decreased ranged between 26-55 mg/l, results of measurement of the value of the ratio N/P before the grant of Ca(OH)2 and NaHCO3 on all points of observation that is ranged between 3.15 – 3.68 while following the grant of Ca(OH)2 & NaHCO3, there is a decrease và an increase in the value of the ratio N/P a row ranges between 1.67 – 1.8 and 13.8 – 15.18. Observations a total mật độ trùng lặp từ khóa of plankton showed before the grant of Ca(OH)2 & NaHCO3 that is in the range 206.250-1.103.125 x104 ind/l whereas after the grant of Ca(OH)2 & there is a decrease in the mật độ trùng lặp từ khóa of NaHCO3 total plankton reach 9.375x104 ind/l. Research has been done gives the conclusion that the grant of Ca(OH)2 and NaHCO3 pH value can increase and may decrease the value of the COD. The ratio N/P và a density of total plankton. Suggestions for research is expected to bởi further research about the grant of Ca(OH)2 and NaHCO3 pH Dynamics against, COD, N/P ratio và abundance of plankton in summer.
