You can use public/private key generation method using ssh-keygen (https://help.ubuntu.com/community/SSH/OpenSSH/Keys) And then use the below script.
for VARIABLE in dir1 dir2 dir3
do
ssh [email protected] mkdir -p $location
scp -r $i [email protected]:$location
done
Alternative solution : You can use sshpass
for VARIABLE in dir1 dir2 dir3
do
ssh [email protected] mkdir -p $location sshpass -p '<password>' <command>
scp -r $i [email protected]:$location sshpass -p '<password>' <command>
done

Please note that the 1st method above is highly preferable (or, even, the only you should use) : the 2nd one can make the password appear to anyone on the system (via 'ps'). And the first one should have the private key only be readable by the user and no others should be able to get it.
While public/private keys is the easiest option, without need to change the existing script, there is another option, of using sshfs. sshfs may not be installed by default.
With this approach, you basically mount the remote file system to a local directory, over ssh protocol. Then you can simply use commands like mkdir / cp etc.
NOTE: These command are from YOUR system & not from REMOTE system.
Mounting over ssh is a one time job, which will require your manual intervention. Do this before running the script.
e.g. for your case:
mkdir /tmp/tam_192.168.174.43
sshfs [email protected]:/ /tmp/tam_192.168.174.43
[email protected]'s password: <ENTER PASSWORD HERE>
& then, in your script, use simple commands like:
mkdir -p /tmp/tam_192.168.174.43/$location
cp -r $i /tmp/tam_192.168.174.43/$location
& to unmount:
fusermount -u /tmp/tam_192.168.174.43
