This one works for me

In View file

<div id="area_input">
  <div id="inputan" class="form-inline">
    <div class="form-group col-sm-6">
      <input type="text" class="form-control" name="size[]" placeholder="ukuran">
    </div>  
    <div class="form-group col-sm-6">
      <input type="text" class="form-control" name="size[]" placeholder="ukuran">
    </div>   
    <div class="form-group col-sm-6">
      <input type="text" class="form-control" name="size[]" placeholder="ukuran">
    </div>
    <div class="form-group col-sm-6">
      <input type="text" class="form-control" name="size[]" placeholder="ukuran">
    </div>            
  </div>  
</div>

you can repeat input as needed.

in Controller file

$data = array(
            'size' => $this->input->post('size'),
        );

You can check stucture of array using print_r($data), or print 'em using:

foreach ($data as $key => $value) {
   foreach ($value as $detail) {
        echo $detail;
        echo "<br>";
    }
}

Change the way name of checkbox written as follows,

<?php foreach ($doc as $row) { ?>
<label>
  <input name="size[]" type="checkbox" value="<?php echo $row['doc']; ?
  >">&nbsp;&nbsp;<?php echo $row['doc']; ?>
</label>
<?php } ?>

And in post method, 

$size_arr = $this->input->post('size');
foreach($size_arr as $v){
  echo $v;
}

if for some reason it is not working then check with,

$size_arr = $_POST['size'];
foreach($size_arr as $v){
  echo $v;
}

EDIT

One more alternative,

$arr = $this->input->post();
$size_arr = $arr['size'];
foreach($size_arr as $v){
  echo $v;
}

Core version,

$arr = $_POST;
$size_arr = $arr['size'];
foreach($size_arr as $v){
  echo $v;
}

No need to use $i in checkbox name in view file just take an array

View file

<?php foreach ($doc as $row) { ?>
<label>
<input name="size[]" type="checkbox" value="<?php echo $row['doc']; ?>">&nbsp;&nbsp;<?php echo $row['doc']; ?>
</label>
<?php  } ?>

Controller

$countsize = count($this->input->post('size'));
for ($i=0; $i<$countsize ; $i++) 
{
   echo $this->input->post('size')[$i];
}

Your html form code should be like below.

<input name="size[<?php echo $i; ?>]" type="checkbox" value="<?php echo $row['doc']; ?>">

Inside controller your code should be like below.

$size = $this->input->post('size');
foreach($size as $sa)  
{
   echo $sa;
}
