$this->db->select("*");
$this->db->from("pemasukan");
$query = $this->db->get();
return $query;
}
view

foreach($finmasuk->result() as $row) { ?>
<tr>

try this:
model
public function finmasuk(){
$this->db->select("*");
$this->db->from("pemasukan");
$query = $this->db->get();
return $query->result();
}
View
<?php if(!empty($finmasuk)){
foreach($finmasuk as $row) { ?>
<tr>
<td><?php echo $row->nomor;?></td>
<td><?php echo $row->tanggal_input;?></td>
<td><?php echo $row->jenis_pemasukan;?></td>
<td><?php echo $row->nominal;?></td>
<td><?php echo $row->keterangan;?></td>
</tr>
<?php }}
else
{ ?>
<tr>
<td colspan="5">No Data Found</td>
</tr>
<?php }?>

You could try a few debugging tricks to check if your query is returning any rows at all.
Controller
public function finmasuk(){
$this->load->model('m_input');
$rowsReturned = $this->m_input->finmasuk()->num_rows();
echo $rowsReturned;
}
Model
public function finmasuk(){
return $this->db->get('pemasukan');
}
Another Option - This checks for query results as an array
Controller
public function finmasuk(){
$this->load->model('m_input');
$resultArray = $this->m_input->finmasuk()->result_array();
var_dump($resultArray);
echo "<br>";
echo "Count - ".count($resultArray); //Get number of rows in
}
Model
public function finmasuk(){
return $this->db->get('pemasukan');
}
