Again, you need to fix the basic problem first. Your structure is bad. There's no point to having hashes with just one key.

Again, it's hard to say what it should be without knowing what this data is and what you are doing with it.

Perhaps the following is what you need?

$VAR1 = [
          [ '13-3:USNJN4SOIMT_N3_N',    '16' ],
          [ '15-73:USNJN4SOIMT_N3_N',   '34' ],
          [ '13-84:USNJN4SOGLONAPUS_N', '34' ],
];

or maybe even

$VAR1 = [
          [ '13-3',  'USNJN4SOIMT_N3_N',   '16' ],
          [ '15-73', 'USNJN4SOIMT_N3_N',   '34' ],
          [ '13-84', 'USNJN4SOGLONAPUS_N', '34' ],
];
