Abstract
Galangan kapal berperan penting dalam menjaga keberlanjutan armada maritim nasional, namun operasionalnya masih didominasi energi berbasis bahan bakar fosil sehingga menimbulkan biaya operasional dan emisi yang tinggi, terutama pada galangan terpencil seperti Dockyard Sorong PT Pertamina Marine Engineering (PME) yang seluruh kebutuhan listriknya dipenuhi generator diesel. Penelitian ini bertujuan menganalisis integrasi konsep Smart Shipyard dan Green Shipyard untuk menurunkan emisi dan meningkatkan efisiensi operasional galangan tersebut. Metode yang digunakan adalah studi kasus dengan mengukur kinerja pada dua dimensi, yaitu dimensi green melalui kerangka Energy Performance Indicator (EPI) yang dibandingkan terhadap Green Port/Shipyard Framework, serta dimensi smart melalui Smart Shipyard Maturity Level (SSML) atas sepuluh modul operasional. Baseline energi dan emisi dihitung dari konsumsi bahan bakar menggunakan faktor emisi DEFRA 2023, kemudian disusun rencana perbaikan terintegrasi berbasis gap EPI dan SSML dengan kerangka Input–Throughput–Output serta prinsip lean–digital–green, dan dinilai kelayakannya melalui cost-benefit analysis. Hasil pengukuran menunjukkan kondisi awal galangan mengonsumsi 341.525 liter diesel per tahun (setara 1.482.675 kWh) dengan emisi 1.106.541 kgCO₂e per tahun, intensitas karbon 0,746 kgCO₂e/kWh, skor Green 2,73, dan kematangan Smart 1,9 dari skala 5 (Level 2 – Monitoring). Setelah penerapan intervensi terintegrasi—terutama substitusi sebagian pembangkitan diesel dengan PLTS 270 kWp dan BESS 1,1 MWh berskema sewa/kWh (OPEX) serta digitalisasi fungsi pendukung—konsumsi diesel turun menjadi 239.999 liter per tahun dan emisi berkurang menjadi 777.597 kgCO₂e per tahun (reduksi 328.944 kgCO₂e atau 29,7%). Intensitas karbon turun menjadi 0,524 kgCO₂e/kWh, fraksi energi terbarukan meningkat dari 40,0% menjadi 66,2%, skor Green naik menjadi 3,45, dan kematangan Smart meningkat menjadi 2,9 (menuju Level 3 – Control). Dari sisi ekonomi, biaya energi tahunan berkurang sekitar Rp1,04 miliar (10,0%) dengan Benefit/Cost Ratio 1,21 sehingga investasi dinyatakan layak. Disimpulkan bahwa integrasi Smart–Green Shipyard mampu menurunkan emisi dan meningkatkan efisiensi operasional secara signifikan, sekaligus menawarkan model transformasi galangan berkelanjutan yang layak secara teknis dan ekonomis serta dapat direplikasi untuk galangan di wilayah terpencil Indonesia.

Shipyards play a vital role in sustaining the national maritime fleet, yet their operations remain dominated by fossil-fuel-based energy that drives high operating costs and emissions, particularly at remote yards such as the Sorong Dockyard of PT Pertamina Marine Engineering (PME), where the entire electricity demand is met by diesel generators. This study aims to analyze the integration of the Smart Shipyard and Green Shipyard concepts to reduce emissions and improve the operational efficiency of the yard. A case-study method is applied, measuring performance across two dimensions: the green dimension through the Energy Performance Indicator (EPI) benchmarked against a Green Port/Shipyard Framework, and the smart dimension through the Smart Shipyard Maturity Level (SSML) across ten operational modules. Energy and emission baselines are computed from fuel consumption using DEFRA 2023 emission factors; an integrated improvement plan is then derived from the measured EPI and SSML gaps using an Input–Throughput–Output framework and a lean–digital–green principle, and its viability is assessed through a cost-benefit analysis. The results show that, at baseline, the yard consumes 341,525 liters of diesel per year (equivalent to 1,482,675 kWh), emitting 1,106,541 kgCO₂e per year, with a carbon intensity of 0.746 kgCO₂e/kWh, a Green score of 2.73, and a Smart maturity of 1.9 out of 5 (Level 2 – Monitoring). After the integrated intervention—chiefly substituting part of the diesel generation with a 270 kWp solar PV plant and a 1.1 MWh BESS under a per-kWh lease scheme (OPEX), together with digitalization of support functions—diesel consumption falls to 239,999 liters per year and emissions decline to 777,597 kgCO₂e per year (a reduction of 328,944 kgCO₂e, or 29.7%). Carbon intensity drops to 0.524 kgCO₂e/kWh, the renewable energy fraction rises from 40.0% to 66.2%, the Green score increases to 3.45, and Smart maturity improves to 2.9 (toward Level 3 – Control). Economically, annual energy cost decreases by about IDR 1.04 billion (10.0%), with a Benefit/Cost Ratio of 1.21, confirming the investment as feasible. It is concluded that Smart–Green Shipyard integration can significantly reduce emissions and improve operational efficiency while offering a technically and economically viable, replicable model of sustainable shipyard transformation for remote regions of Indonesia.
