SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'order clause'

I got this error when i run edit method.

SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'order clause' (SQL: select * from tbl_departement order by 1 desc limit 15 offset 0)

here is the method in my controller:

public function edit($id){
    $page = session('departementPage');
    $edit = Departement::find($id);
    $departement = Departement::orderBy('id_departement','asc')->paginate($page);
    return view('/akun/admin_0/departement/index')->with('edits',$edit)->with('departements',$departement)->with('sort','1')->with('page',$page);
}

public function update(Request $request, $id){
    if ($request->input_id_departement != '') {
        $get_id_departement = Departement::where('id_departement','=',$request->input_id_departement)->where('id_departement','!=',$id)->count();
        if ($get_id_departement > 0) {
            return redirect()->back()->with('message','ID Departement sudah digunakan \n silahkan masukan ID Departement lainnya!');
        }else{
            Departement::find($id)->update([
                'id_departement' => $request->input_id_departement,
                'nama_departement' => $request->input_nama_departement
            ]   );
            return redirect('/departement')->with('message','Data departement berhasil diupdate');
        }
    }else{
        Departement::find($id)->update([
            'id_departement' => $id,
            'nama_departement' => $request->input_nama_departement
        ]   );
        return redirect('/departement')->with('message','Data departement berhasil diupdate');
    }
}

here is the Departement.php:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Departement extends Model
{
    protected $table="tbl_departement";
    protected $primaryKey="id_departement";
    public $incrementing=false;
    public $timestamps=false;
    protected $fillable=[
    'id_departement','nama_departement'
    ];
}
