Abstract

Industri maritim saat ini berada di bawah tekanan global yang semakin kuat untuk menurunkan emisi gas rumah kaca. Upaya ini diwujudkan melalui penerapan regulasi Carbon Intensity Indicator (CII) oleh International Maritime Organization (IMO). Penelitian ini dilakukan untuk mengkaji kinerja operasional, tingkat konsumsi bahan bakar, serta intensitas karbon pada KM Ciremai dan KM Dobonsolo, sekaligus menilai pengaruh tindakan repowering terhadap peningkatan efisiensi energi kapal. Kedua kapal yang menjadi objek penelitian telah melewati usia ekonomis operasionalnya, yaitu KM Ciremai dengan usia 34 tahun dan KM Dobonsolo 33 tahun. Penelitian ini menganalisis kinerja Carbon Intensity Indicator (CII) pada kapal penumpang KM Dobonsolo dan KM Ciremai sebagai dasar pengambilan keputusan operasional dalam mendukung kebijakan dekarbonisasi pelayaran. Metode penelitian meliputi evaluasi CII eksisting, analisis tren penurunan rating CII berbasis proyeksi, serta simulasi optimasi kecepatan operasi. Hasil menunjukkan bahwa pada tahun 2025 KM Dobonsolo memperoleh rating CII kategori D dengan nilai Required CII 22,77, sekitar 2,5% lebih buruk dibandingkan KM Ciremai yang berada pada kategori C dengan nilai 22,22. Proyeksi jangka panjang menunjukkan kecenderungan penurunan rating CII pada kedua kapal seiring pertambahan umur kapal, yang berdampak pada peningkatan konsumsi bahan bakar dan intensitas karbon. KM Ciremai diproyeksikan mencapai rating E pada periode 2029–2035, sedangkan KM Dobonsolo pada periode 2031–2035. Simulasi menunjukkan bahwa optimasi kecepatan hingga 18 knot berpotensi menurunkan konsumsi bahan bakar tahunan sekitar 31,5% pada KM Dobonsolo dan 29,0% pada KM Ciremai. Hasil penelitian menegaskan bahwa optimasi kecepatan merupakan strategi efektif untuk menekan emisi dan memperlambat penurunan rating CII

The maritime industry is currently under increasing global pressure to reduce greenhouse gas emissions. This effort is reflected in the implementation of the Carbon Intensity Indicator (CII) regulation by the International Maritime Organization (IMO). This study aims to evaluate the operational performance, fuel consumption, and carbon intensity of the passenger vessels KM Ciremai and KM Dobonsolo, as well as to assess the impact of repowering measures on improving ship energy efficiency. Both vessels examined in this study have exceeded their economic operational lifetimes, with KM Ciremai operating for 34 years and KM Dobonsolo for 33 years. This research analyzes the Carbon Intensity Indicator (CII) performance of KM Dobonsolo and KM Ciremai as a basis for operational decision-making in support of maritime decarbonization policies. The methodology includes an assessment of existing CII performance, trend analysis of projected CII rating degradation, and simulations of operational speed optimization. The results indicate that in 2025, KM Dobonsolo achieved a CII rating of category D with a Required CII value of 22.77, approximately 2.5% worse than KM Ciremai, which achieved a category C rating with a Required CII value of 22.22. Long-term projections reveal a continuous decline in CII ratings for both vessels as they age, leading to increased fuel consumption and carbon intensity. KM Ciremai is projected to reach a CII rating of category E during the period 2029–2035, while KM Dobonsolo is expected to reach category E during 2031–2035. Simulation results demonstrate that optimizing operational speed to 18 knots can reduce annual fuel consumption by approximately 31.5% for KM Dobonsolo and 29.0% for KM Ciremai. The findings confirm that operational speed optimization is an effective strategy for reducing emissions and slowing the deterioration of CII ratings.
