I used form and view in one page are this is the problem
This is my model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Kwitansi extends Model
{
// $id = IdGenerator::generate(['table' => 'kwitansis', 'length' => 10, 'prefix' =>'PM-INV-']);
protected $table = 'kwitansis';
protected $fillable = [
'received',
'registration',
'course',
'trasnportation',
'sum_rp',
'payment',
'register_at',
];
protected $primarykey = 'id';
public $increment = false;
protected $keyType = 'string';
}

Answer 1

Remove these lines from your model:
protected $primarykey = 'id';
public $increment = false;
protected $keyType = 'string';

Answer 2

Ok Thanks Guys For Helping, I Have Solved The Problem.
I Only Delete Some function on Controller adn Worked for Me
$request->validate([
'sum_rp' => 'required',
'sum_text' => 'required',
]);
$sum_rp = $request->registration + $request->course + $request->transportation;
function penyebut($nilai) {
$nilai = abs($nilai);
$huruf = array("", "satu", "dua", "tiga", "empat", "lima", "enam", "tujuh", "delapan", "sembilan", "sepuluh", "sebelas");
$temp = "";
if ($nilai < 12) {
$temp = " ". $huruf[$nilai];
} else if ($nilai <20) {
$temp = penyebut($nilai - 10). " belas";
} else if ($nilai < 100) {
$temp = penyebut($nilai/10)." puluh". penyebut($nilai % 10);
} else if ($nilai < 200) {
$temp = " seratus" . penyebut($nilai - 100);
} else if ($nilai < 1000) {
$temp = penyebut($nilai/100) . " ratus" . penyebut($nilai % 100);
} else if ($nilai < 2000) {
$temp = " seribu" . penyebut($nilai - 1000);
} else if ($nilai < 1000000) {
$temp = penyebut($nilai/1000) . " ribu" . penyebut($nilai % 1000);
} else if ($nilai < 1000000000) {
$temp = penyebut($nilai/1000000) . " juta" . penyebut($nilai % 1000000);
} else if ($nilai < 1000000000000) {
$temp = penyebut($nilai/1000000000) . " milyar" . penyebut(fmod($nilai,1000000000));
} else if ($nilai < 1000000000000000) {
$temp = penyebut($nilai/1000000000000) . " trilyun" . penyebut(fmod($nilai,1000000000000));
}
return $temp;
}
function terbilang($nilai) {
if($nilai<0) {
$hasil = "minus ". trim(penyebut($nilai));
} else {
$hasil = trim(penyebut($nilai));
}
return $hasil;
}
$sum_text = $request->sum_rp;
$kwitansi->sum_rp = $sum_rp;
$kwitansi->sum_text = terbilang($sum_text);
Only Delete This function and add it to Helper Class
