Laravel Migration Type Year become undefined Method

i have a problem with my migration on laravel 5.8. I try to make Year Column as mentioned in documentation. But i get this error "[Symfony\Component\Debug\Exception\FatalThrowableError] Call to undefined method Illuminate\Database\Schema\Blueprint::year()".

this is my migration file :

Schema::create('pengajuan_arsip', function(Blueprint $table) {
        $table->increments('id');
        $table->uuid('uuid');
        $table->integer('id_pegawai_pengaju');
        $table->string('nip_pengaju',50);
        $table->string('nik_pengaju',50);
        $table->string('nama_pengaju',200);
        $table->string('bidang',100);
        $table->string('sub_bidang',100);
        $table->string('tingkat',50);
        $table->integer('status');
        $table->boolean('is_setuju');
        $table->integer('setuju_kasi_by');
        $table->year('tahun_mulai');
        $table->year('tahun_akhir');
        $table->timestamps();
        $table->softDeletes();
    });

    Schema::create('detail_histori_arsip', function(Blueprint $table) {
        $table->increments('id');
        $table->uuid('uuid');
        $table->integer('id_pengajuan_arsip');
        $table->integer('status');
        $table->integer('status_by');
        $table->integer('diambil_by');
        $table->date('tanggal_diambil');
        $table->integer('id_ruang_arsip');
        $table->date('tanggal_pindah');
        $table->timestamps();
    });

    Schema::create('detail_arsip', function(Blueprint $table) {
        $table->increments('id');
        $table->uuid('uuid');
        $table->integer('id_pengajuan_arsip');
        $table->string('nama_dokumen',200);
        $table->year('tahun_dokumen');
        $table->timestamps();
    });
