Contamination of the heavy metal copper (Cu) in water has a negative effect to decrease cell function and causes organ damage on the organism. The quality of river’s water is influenced by the level of salinity concentration. The higher salinity concentration of wateris capable of causing damage and degrading cell function. The aim of this study is to determine the effect and correlation of the provision of variations in the concentration of heavy metal copper (Cu) and variations in salinity concentration on the quality of spermatozoa Tilapia (Oreochromis niloticus). There are 24treatment variations in heavy metal copper (Cu) concentration (0 ppm, 0.01 ppm, 0.05 ppm, 0.1 ppm, 0.5 ppm, and 1 ppm) and variations in salinity concentration (0 ppt, 4 ppt, 6ppt, and 8 ppt) with four times replication. The parameters measured by duration of mass motility, duration of individual motility, and viability of spermatozoa. The result showed that the highest viability and motility of spermatozoa was the 0,01-ppm test group on copper heavy metals and 4 ppt on salinity, and the decrease in viability and motility of spermatozoa began to occur in the administration of salinity concentrations of 6 ppt and 0.05 ppm on copper metals. This study highlights the viability and duration of motility of spermatozoa Oreochromis niloticus. Salinity and heavy metal copper (Cu) decrease the viability and duration of motility of spermatozoa Oreochromis niloticus.
