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

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
