Abstract

Penelitian ini menganalisis potensi pemanfaatan karbon dioksida (CO2) dari pembangkit listrik tenaga uap (PLTU) untuk kebutuhan industri pupuk, dengan fokus pada aspek transportasi laut, biaya terkait, dan potensi profit. Penelitian ini bertujuan untuk menghitung emisi CO2 yang dihasilkan oleh PLTU, menentukan jumlah emisi yang dapat ditangkap menggunakan teknologi Carbon Capture, dan mengembangkan skenario pengiriman CO2 yang efisien dari pembangkit listrik ke industri pupuk. Pendekatan yang digunakan meliputi perhitungan emisi berdasarkan pedoman Direktorat Jenderal Ketenagalistrikan, analisis kebutuhan CO2 industri pupuk melalui stoikiometri dan pengembangan model Vehicle Routing Problem untuk optimasi transportasi laut. Hasil penelitian menunjukkan bahwa PLTU Indramayu dan PLTGU Tambak Lorok merupakan pemasok CO2 yang optimal, dengan biaya pengiriman terendah dicapai melalui skema pengiriman curah dan pemanfaatan Terminal Untuk Kepentingan Sendiri (TUKS), masing-masing sebesar 18.700.078 Jt-Rp dan 19.801.438 Jt-Rp. Biaya investasi dan operasional teknologi Carbon Capture untuk PLTU Indramayu mencapai 21.300.807 Jt-Rp dan 3.832.339 Jt-Rp per tahun, sedangkan untuk PLTGU Tambak Lorok sebesar 14.433.402 Jt-Rp dan 547.968 Jt-Rp per tahun. Biaya pajak karbon untuk pembangkit yang tidak terpilih, seperti PLTU Suralaya dan PLTU Tanjung Jati B, masing-masing sebesar 3.409.731 Jt-Rp dan 2.343.666 Jt-Rp. Profit per m3 CO2 yang dihasilkan adalah Rp1.567.300 untuk PLTU Indramayu dan Rp1.638.118 untuk PLTGU Tambak Lorok, dengan total profit sebesar 155.643.035 Jt-Rp. Analisis rasio manfaat-biaya menghasilkan nilai 1,13, menunjukkan kelayakan ekonomi proyek. Analisis sensitivitas menunjukkan bahwa peningkatan volume muatan menurunkan biaya unit, meskipun penambahan moda transportasi menyebabkan pola biaya zigzag. Penelitian ini memberikan kontribusi terhadap strategi keberlanjutan melalui pemanfaatan kembali CO2 dan optimasi transportasi laut.

This study analyzes the potential utilization of carbon dioxide (CO2) from coal-fired power plants (PLTU) for the fertilizer industry, focusing on maritime transportation, associated costs, and potential profits. The research aims to calculate CO2 emissions produced by PLTUs, determine the amount of emissions capturable using Carbon Capture and Storage (CCS) technology, and develop efficient CO2 transportation scenarios from power plants to fertilizer industries. The methodology includes emission calculations based on guidelines from the Directorate General of Electricity, analysis of CO2 requirements in the fertilizer industry using stoichiometry, and the development of a Vehicle Routing Problem model for optimizing maritime transportation. The results indicate that PLTU Indramayu and PLTGU Tambak Lorok are optimal CO2 suppliers, achieving the lowest transportation costs through bulk shipping and the utilization of Dedicated Terminals (TUKS), amounting to 18.700.078 Mio-Rp and 19.801.438 Mio-Rp, respectively. The investment and operational costs for CCS technology at PLTU Indramayu are 21.300.807 Mio-Rp and 3.832.339 Mio-Rp per year, while for PLTGU Tambak Lorok, they are 14.433.402 Mio-Rp and 547.968 Mio-Rp per year. Carbon tax costs for non-selected power plants, such as PLTU Suralaya and PLTU Tanjung Jati B, amount to 3.409.731 Mio-Rp and 2.343.666 Mio-Rp, respectively. The profit per cubic meter of CO2 is Rp1.567.300 for PLTU Indramayu and Rp1.638.118 for PLTGU Tambak Lorok, with a total profit of 155.643.035 Mio-Rp. The benefit-cost ratio analysis yields a value of 1,13, indicating the project’s economic feasibility. Sensitivity analysis shows that increasing shipment volumes reduces unit costs, although additional transportation modes result in a zigzag cost pattern. This study contributes to sustainability strategies through the reuse of CO2 and optimization of maritime transportation.
