Abstract
Laut Indonesia memiliki peranan penting bagi kehidupan bangsa dan negara. Salah satunya dalam hal transportasi. Indonesia memiliki beberapa pelabuhan utama, salah satunya adalah Pelabuhan Tanjung Perak. Sejak tahun 2010 Pelabuhan Tanjung Perak menaungi 2 perusahaan kapal, salah satunya adalah PT Pelni (Persero). Sebesar 41% dari total penumpang angkutan laut di Indonesia pada tahun 2017 menggunakan jasa PT Pelni (Persero). Tingginya kebutuhan pelayanan di PT Pelni (Persero) mengharuskan perusahaan memiliki database yang baik. Namun dikarenakan human error, data perusahaan tahun 2017 hilang. Pada penelitian ini akan didapatkan model terbaik untuk peramalan jumlah penumpang angkutan laut rute Surabaya-Jayapura di PT Pelni (Persero) untuk tahun 2017 dengan menggunakan metode A-RIMA Box-Jenkins dan regresi time series efek variasi kalen-der dengan residual data dilanjutkan dengan ARIMA Box-Jenkins. Efek variasi kalender digunakan karena pergeseran bulan terjadinya Hari Raya Idul Fitri. Hasil penelitian me-nunjukkan bahwa peramalan dengan menggunakan regresi ti-me series memberikan hasil yang lebih baik dibandingkan de-ngan metode ARIMA Box-Jenkins karena nilai MAPE dan AIC yang dihasilkan cendrung lebih kecil.
