Code :

foreach ($data['garduinduk'] as $key => $gi){
            foreach ($ready as $rdy){
                if ($rdy->lokasi == $gi->id){ 
                    if ($rdy->status == 'On_progress'){
                        $gi->berlaku_dari = 'ON PROGRESS';
                        $gi->berlaku_sampai = 'ON PROGRESS';
                        $gi->file = 'ON PROGRESS';
                    }else{ 
                        $gi->berlaku_dari = $rdy->berlaku_dari;
                        $gi->berlaku_sampai = $rdy->berlaku_sampai;
                        $gi->file = $rdy->file;
                    }

                }else{
                    $gi->berlaku_dari = '';
                    $gi->berlaku_sampai = '';
                    $gi->file = '';
                }
            }
        }

Answer 1

Use reference on $gi

foreach ($data['garduinduk'] as $key => &$gi){

or use

$data['garduinduk'][$key]->

instead of

$gi->
