Abstract

Jembatan Mahakam di Samarinda merupakan titik lintas wajib rangkaian tunda-tongkang batubara Kalimantan Timur. Keterbatasan bentang bebas alur antar pilar mewajibkan proses pengolongan yaitu terdiri dari pemanduan-penundaan kapal oleh tugboat assist melewati kolong jembatan, sementara kapasitas layanan dibatasi tiga unit tugboat dengan jendela operasional tetap 8 jam per hari berpola blok 4-2-4. Penelitian ini mengukur kinerja operasional eksisting dan menentukan jumlah tugboat optimal untuk proyeksi 2025 hingga 2029. Metode yang digunakan adalah trace-driven discrete event simulation berbasis Python yang memutar ulang 19.437 kedatangan aktual selama 185 hari (105,06 kapal per hari), dengan pembangkitan kedatangan bootstrap beridentitas nama kapal nyata dan alternasi arah, pertumbuhan permintaan 4,04 persen per tahun mengikuti PDRB Kalimantan Timur, eksperimen grid enam skenario armada (3 hingga 8 unit) sebanyak 30 replikasi, serta tujuh pengujian verifikasi-validasi yang seluruhnya lulus. Hasilnya, konfigurasi eksisting kelebihan beban struktural: hanya 93,2 kapal per hari terlayani pada utilisasi 99,7 persen, dengan backlog akhir 2.192 kapal dan median waktu tunggu antrean 177,3 jam. Jumlah tugboat optimal adalah 5 unit pada 2025 hingga 2028 dan 6 unit mulai 2029, yang menjaga coverage 100 persen (99,82 persen pada 2029) dengan waktu tunggu rata-rata 9,55 hingga 10,91 jam dan utilisasi armada terkendali terhadap ambang perencanaan 85 persen. Jalur rekomendasi menghasilkan pendapatan kumulatif Rp 418,44 miliar dari 220.232 kapal terlayani dan laba operasional Rp 143,67 miliar terhadap belanja modal Rp 25,05 miliar. Kata kunci: Jembatan Mahakam, Kapasitas Operasional, Pengolongan Kapal, Simulasi Kejadian Diskrit, Tugboat, Waktu Tunggu.

The Mahakam Bridge in Samarinda is a mandatory passing point for the coal tug-and-barge convoys of East Kalimantan. The limited navigable clearance between its piers makes the pengolongan process tug-assisted escort of vessels through the bridge span compulsory, while service capacity is limited to three assist tugboats within a fixed 8-hour daily operating window arranged in a 4-2-4 block pattern. This research measures the existing operational performance and determines the optimal number of tugboats for the 2025–2029 projection. The method is a Python-based trace-driven discrete event simulation replaying 19,437 actual arrivals recorded by over 185 days (105.06 vessels per day), featuring bootstrap arrival generation with real vessel identities and direction alternation, demand growth of 4.04 percent per year following East Kalimantan GRDP, a grid experiment of six fleet scenarios with 30 replications, and seven verification-validation tests, all passed. Results show the existing configuration is structurally overloaded: only 93.2 vessels per day are served at 99.7 percent utilization, leaving a final backlog of 2,192 vessels and a median queueing time of 177.3 hours. The optimal fleet is 5 units for 2025–2028 and 6 units from 2029, maintaining 100 percent coverage (99.82 percent in 2029) with average waiting times of 9.55 to 10.91 hours and fleet utilization controlled against the 85 percent planning threshold. The recommended path generates cumulative revenue of IDR 418.44 billion from 220,232 served vessels and an operating profit of IDR 143.67 billion against a capital expenditure of IDR 25.05 billion.
