Abstract

Indonesia sebagai negara kepulauan sangat bergantung pada transportasi laut dalam mendukung konektivitas wilayah serta distribusi logistik nasional. Dalam sistem penggerak kapal, propeller merupakan komponen utama yang berfungsi sebagai pendorong saat kapal beroperasi, namun rentan mengalami kerusakan akibat kelelahan material, kavitasi, dan beban operasi jangka panjang. Kerusakan propeller dapat menurunkan performa kapal, meningkatkan konsumsi bahan bakar, serta berkontribusi terhadap peningkatan emisi gas rumah kaca. Tanpa strategi pemeliharaan yang tepat, praktik penggantian propeller secara berulang berpotensi meningkatkan beban emisi dan biaya karbon, sehingga menghambat pencapaian target dekarbonisasi sektor maritim. Seiring dengan penerapan carbon pricing dan meningkatnya tuntutan keberlanjutan, diperlukan strategi pemeliharaan propeller Revisi 1yang lebih efisien dan berkelanjutan. Penelitian ini menerapkan Life Cycle Assessment (LCA) dengan menggunakan Software SimaPro untuk membandingkan dampak lingkungan antara propeller baru dan strategi perbaikan (repair). Hasil penelitian menunjukkan bahwa proses rancangan alur siklus hidup propeller pada manufaktur propeller kapal memiliki hotspot atau kontribusi dampak lingkungan yang lebih besar dibandingkan dengan proses repair. Kemudian dilakukan klasifikasi yang berfokus pada kategori global warming, dimana hasil menunjukkan proses manufaktur tetap memiliki dampak luaran paling besar dibanding repair, memperkuat hasil penelitian dilakukan prediksi environmental cost melalui skenario carbon tax Indonesia dan terbukti strategi repair terbukti memiliki biaya lingkungan yang lebih rendah dan memberikan manfaat ekonomi sekaligus pada lingkungan. Temuan ini menegaskan bahwa strategi repair tidak hanya menurunkan emisi, tetapi juga memberikan manfaat ekonomi melalui penghematan biaya karbon dengan potensi saving yang diperkirakan meningkat seiring perkembangan kebijakan carbon tax di masa depan.

Indonesia, as an archipelagic country, relies heavily on maritime transportation to support regional connectivity and national logistics distribution. In ship propulsion systems, the propeller is a key component that generates thrust during operation; however, it is highly susceptible to damage due to material fatigue, cavitation, and long-term operational loads. Propeller damage can reduce vessel performance, increase fuel consumption, and contribute to higher greenhouse gas emissions. Without appropriate maintenance strategies, repeated propeller replacement may lead to greater environmental burdens and carbon-related costs, thereby hindering the decarbonization targets of the maritime sector. Along with the implementation of carbon pricing policies and increasing sustainability demands, more efficient and sustainable propeller maintenance strategies are required. This study applies Life Cycle Assessment (LCA) using SimaPro software to compare the environmental impacts of manufacturing new propellers and implementing repair strategies. The results indicate that the life cycle stages of new propeller manufacturing generate higher environmental hotspots and contribute more significantly to overall impacts than repair processes. Focusing on the global warming impact category, manufacturing remains the largest contributor compared to repair scenarios. Furthermore, an environmental cost prediction was conducted by integrating the Indonesian carbon tax scheme, demonstrating that repair strategies result in lower environmental costs while providing both economic and environmental benefits. These findings highlight that propeller repair not only reduces emissions but also offers financial advantages through carbon cost savings, with greater potential benefits expected as carbon tax policies continue to develop in the future.
