Abstract

Meningkatnya timbulan sampah di Indonesia dan ketergantungan industri semen pada batu bara memerlukan distribusi Refuse Derived Fuel (RDF) yang efisien. Penelitian ini menggunakan model optimasi Integer Linear Programming (ILP) untuk meminimalkan biaya distribusi dari 40 titik supply ke 5 pabrik semen. Model ini menggunakan beberapa skema pengiriman, termasuk rute darat langsung dan rute laut dengan beberapa tahap dan mempertimbangkan kapasitas supply. Hasil menunjukkan potensi supply RDF sebesar 925.640 ton terhadap kapasitas penerimaan pabrik sebesar 4.814.078 ton. Unit cost pengiriman pada skenario I sebesar Rp261.835/ton dengan total emisi setelah menggunakan RDF sebesar 6.953.951 tCO₂, sementara pada skenario II sebesar Rp261.874/ton dengan total emisi yang sama, yaitu 6.953.951 tCO₂. Pada skenario III (supply sebesar 50% dari kapasitas pabrik), unit cost pengiriman meningkat menjadi Rp 432.045/ton dengan total emisi 5.407.783 tCO₂. Selanjutnya, pada skenario IV (supply melebihi kapasitas pabrik), biaya mencapai Rp 518.296/ton dengan total emisi sebesar 3.619.136 tCO₂. Jika dibandingkan dengan kondisi eksisting yang memiliki unit cost pengiriman sebesar Rp157.457/ton dengan total emisi 7.730.136 tCO₂, skenario dalam penelitian ini memang menghasilkan unit cost yang lebih tinggi. Namun, skenario tersebut mampu memaksimalkan penyerapan sampah dan menghasilkan pengurangan emisi karbon yang jauh lebih besar.

The increasing waste generation in Indonesia and the dependency of the cement industry on coal require an efficient distribution of Refuse Derived Fuel (RDF). This study uses an Integer Linear Programming (ILP) optimization model to minimize distribution costs from 40 supply points to 5 cement plants. The model incorporates several shipping schemes, including direct land routes and multi-stage sea routes, considering supply capacity. The results show a potential RDF supply of 925.640 tons against a plant reception capacity of 4.814.078 tons. In Scenario I, the unit shipping cost is Rp261.835/ton with a total emission after RDF use of 6.953.951 tCO₂, while Scenario II has the same total emission at Rp261.874/ton. In Scenario III (50% supply of plant capacity), the shipping cost rises to Rp432.045/ton with total emissions of 5.407.783 tCO₂. Scenario IV (supply exceeding plant capacity) sees costs of Rp518.296/ton and total emissions of 3.619.136 tCO₂. Compared to the existing condition with a shipping cost of Rp157.457/ton and total emissions of 7.730.136 tCO₂, the proposed scenarios have higher costs but significantly reduce carbon emissions and maximize waste absorption.
