$result = $this->MsLaporan->dataNullByKecamatan($dateStart, $dateEnd, $kategori, $keykecamatan['IDKecamatan']);
if ($result == NULL) {
$row = array(
"NamaKecamatan" => $keykecamatan['NamaKecamatan'],
"total" => 0,
"laki" => 0,
"cewe" => 0,

Answer 1

$data = '[{"data":{"NamaKecamatan":"BEJI","total":"2","laki":"1","cewe":"1"}},
{"data":{"NamaKecamatan":"BOJONGSARI","total":0,"laki":0,"cewe":0}},
{"data":{"NamaKecamatan":"CILODONG","total":"2","laki":"1","cewe":"1"}},
{"data":{"NamaKecamatan":"CIMANGGIS","total":"4","laki":"2","cewe":"2"}}]';
$array_data = json_decode($data, ture);
$result = [];
foreach($array_data as $item) {
$result['data'][] = $item['data'];
}
return json_encode($result);

You can approach this as following
public function countByKecamatan(){
$kecamatan = $this->db->query("SELECT IDKecamatan, NamaKecamatan FROM mskecamatan ORDER BY NamaKecamatan ASC")->result_array();
$i = 0;
foreach ($kecamatan as $keykecamatan) {
$result = $this->MsLaporan->dataNullByKecamatan($dateStart, $dateEnd, $kategori, $keykecamatan['IDKecamatan']);
if ($result == NULL) {
$row = array(
"NamaKecamatan" => $keykecamatan['NamaKecamatan'],
"total" => 0,
"laki" => 0,
"cewe" => 0,
);
}else{
$row = $result[0];
}
($i > 0) ? ($data[] = $row) : ($data = array('data' => $row));
$i++;
}
echo json_encode($data);
}

The output your getting is down to 2 minor problems in the lines...
$data = array(
"data" => $row,
);
echo json_encode($data);
The first is that you are building the array with the extra level which you say you want to remove. The second line of code then echos each piece of data one at a time. You need to build up a list of all of the records and then return the full data in one go.
public function countByKecamatan(){
// Create empty array for data
$data = [];
$kecamatan = $this->db->query("SELECT IDKecamatan, NamaKecamatan FROM mskecamatan ORDER BY NamaKecamatan ASC")->result_array();
foreach ($kecamatan as $keykecamatan) {
$result = $this->MsLaporan->dataNullByKecamatan($dateStart, $dateEnd, $kategori, $keykecamatan['IDKecamatan']);
if ($result == NULL) {
$row = array(
"NamaKecamatan" => $keykecamatan['NamaKecamatan'],
"total" => 0,
"laki" => 0,
"cewe" => 0,
);
}else{
$row = $result[0];
}
// Add new row of data to data to be returned
$data[] = $row;
}
// Return all of the data in JSON format
return json_encode($data);
}
Note that this returns the value rather than echos it - you may need to change this if when you call the controller, your framework needs to encode it some other way (i.e. as part of a Response object).
