What's the second one for, could you explain please??

This is your change.
Bitcoins do exist as UTXO (Unspent transaction outputs).
Each transaction takes UTXO's (inputs of the new transactions) to create new UTXO's (output of the transaction).

In your case:
The input of your transaction was an unspent output (0.005486 BTC).
You have created two 'new UTXOs' (The payment you wanted to do (0.000848) and your change (0.0046342 BTC)).
Those two values sum up to 0.0054822. Plus your fee of 0.0000038 BTC this equals your input.

Thanks for that explanation! It really clarified it.

What about this previous transaction:

What's 0.000072 here?
