public function getMei()
{
    $data['users'] = DB::table('lembur_karyawan')
            ->selectRaw('SEC_TO_TIME(SUM(timeSpent)) as  total_lembur') 
            ->groupBy('nama')
            ->havingRaw('SUM(total)')

Answer 2

Use

DB::raw('SEC_TO_TIME( SUM( TIME_TO_SEC( `timeSpent` ) ) ) as total_lembur')

MySQL autoconverts time to hours and you have to explicitly convert value by either TIME_TO_SEC or UNIX_TIMESTAMP.
