Abstract

Pengelolaan limbah operasional kapal di pelabuhan Indonesia menghadapi tantangan besar dalam pemenuhan standar internasional MARPOL 73/78, terutama terkait disparitas infrastruktur dan koordinasi antarlembaga. Penelitian ini bertujuan untuk mengevaluasi dan menentukan metode pembuangan limbah yang paling optimal di Pelabuhan Tanjung Perak, Gresik, dan Semarang melalui integrasi metode Dependency Matrix dan Analytic Hierarchy Process (AHP). Struktur hierarki keputusan yang dibangun mencakup 5 kriteria utama teknis, operasional, ekonomi, keselamatan, dan aspek lainnya serta 17 sub-kriteria spesifik. Penggunaan Dependency Matrix dalam penelitian ini berfungsi sebagai instrumen kalibrasi untuk mengatasi subjektivitas pada skala Saaty, sehingga menghasilkan pembobotan yang lebih objektif berdasarkan interdependensi kausal antar elemen. Hasil analisis menunjukkan variasi prioritas yang signifikan berdasarkan klasifikasi pelabuhan. Pada pelabuhan kelas utama, kriteria teknis mendominasi dengan bobot 0,323, sementara pada pelabuhan kelas satu, aspek pendukung lainnya menjadi prioritas utama (0,300). Sebaliknya, pelabuhan kelas dua sangat menitikberatkan pada dimensi teknis (0,427) dalam pengambilan keputusan. Berdasarkan pengolahan data AHP, alternatif "Kapal–Truk–Pembuangan di Luar Pelabuhan" terbukti menjadi solusi paling efektif untuk pelabuhan kelas utama (0,362) dan kelas satu (0,352). Namun, bagi pelabuhan kelas dua, alternatif "Kapal–Truk–Receiving di Pelabuhan" (0,359) dinilai lebih optimal. Analisis sensitivitas dengan variasi bobot hingga kurang lebih 10% mengonfirmasi stabilitas keputusan di Tanjung Perak dan Gresik. Di Pelabuhan Semarang, meski ditemukan sensitivitas terhadap kriteria teknis, tidak terjadi perubahan peringkat alternatif secara ekstrem (rank reversal). Temuan ini memberikan kerangka kerja strategis bagi otoritas pelabuhan dalam mengimplementasikan sistem manajemen limbah maritim yang lebih robust dan berkelanjutan di Indonesia.

The management of ship operational waste in Indonesian ports faces significant challenges in complying with international MARPOL 73/78 standards, primarily due to infrastructure disparities and fragmented institutional coordination. This study aims to evaluate and determine the most optimal waste disposal methods at Tanjung Perak, Gresik, and Semarang ports by integrating the Dependency Matrix and the Analytic Hierarchy Process (AHP). The established decision hierarchy consists of 5 main criteria technical, operational, economic, safety, and other aspects alongside 17 specific sub-criteria. The application of the Dependency Matrix serves as a calibration instrument to address subjectivity within Saaty's scale, resulting in more objective weighting based on the causal interdependencies between elements. The analysis reveals significant priority variations based on port classification. In main-class ports, technical criteria dominate with a weight of 0.323, whereas in first-class ports, other supporting aspects become the primary priority (0.300). Conversely, second-class ports place a heavy emphasis on the technical dimension (0.427) in decision-making. Based on AHP processing, the "Ship–Truck–Disposal Outside Port" alternative is proven to be the most effective solution for main-class (0.362) and first-class (0.352) ports. However, for second-class ports, the "Ship–Truck–Receiving at Port" (0.359) alternative is considered more optimal. Sensitivity analysis with weight variations up to 10% confirms high decision stability in Tanjung Perak and Gresik. In Semarang Port, despite sensitivity to technical criteria, no extreme rank reversal occurred. These findings provide a strategic framework for port authorities to implement a more robust and sustainable maritime waste management system in Indonesia.
