ua741 DC offset on the output
The 741 (a dinosaur that is well-past its sell-by date) cannot handle inputs close to either supply rail. If you want the input to reduce to 0 volts and get 0 volts on the output then you'll need a negative supply rail.
Reasons not to use a 741 op-amp tells you about this problem in the answer - see the main bullet point 2: Input voltage range is typically from -Vs + 2 volt to +Vs - 2 volt and main bullet point 7: Typical output voltage swing is -Vs + 1 volt to +Vs - 1 volt
