How to get single record from one to many relationship in laravel

i have one to many relationship in my models and it works as i want, but sometime i only need one record to be returned (not as an array of collection). Here is my controller

$sesi = Sesi::with('jadwal.mapelLokal.guru','jadwal.mapelLokal.matapelajaran')->whereHas('jadwal',function($jadwal) use ($r) {
            $jadwal->whereHas('mapelLokal',function($mapel) use($r) {
                $mapel->where('id_lokal',$r->lokal);
            });
        })->get();

Sesi Model

class Sesi extends Model
{
    protected $table = 'sesi';
    public $timestamps = false;

    public function jadwal()
    {
        return $this->hasMany('SIAStar\Jadwal','id_sesi');
    }
}

jadwal model

class Jadwal extends Model
{
    protected $table= 'jadwal';
    public $timestamps = false;

    public function mapelLokal()
    {
        return $this->belongsTo('SIAStar\MapelLokalGuru','id_mapel_lokal');
    }
}

and MapelLokalGuru

class MapelLokalGuru extends Model
{
    protected $table = 'mapel_lokal_guru';
    protected $fillable = ['id_lokal','mapel_id','guru_id'];
    public $timestamps=false;

    public function mataPelajaran()
    {
        return $this->belongsTo('SIAStar\MataPelajaran','mapel_id');
    }
    public function guru()
    {
        return $this->belongsTo('SIAStar\Guru','guru_id');
    }
    public function formNilai()
    {
        return $this->hasMany('SIAStar\FormNilai','id_mapel_lokal');
    }
    public function lokal()
    {
        return $this->belongsTo('SIAStar\Lokal','id_lokal');
    }
    public function postMateri()
    {
        return $this->hasMany('SIAStar\PostKelasOnline','id_mapel_lokal');
    }
}

and the result of controller is like this

    Collection {#454 ▼
      #items: array:2 [▼
        0 => Sesi {#452 ▼
          #table: "sesi"
//...
          #relations: array:1 [▼
            "jadwal" => Collection {#468 ▼
              #items: array:1 [▶]
            }
          ]
        }
      ]
    }

as you se, jadwal relationship returning a collection, but what i want is only single record since it's only has one record. How to querying nested relationship so jadwal relationship only return one data?
