Transisi energi Indonesia menuju energi bersih memerlukan evaluasi komprehensif terhadap skenario blending bahan bakar alternatif yang praktis dan implementable. Penelitian ini menganalisis sensitivitas sembilan skenario blending small-scale LNG (ssLNG) dan Sustainable Aviation Fuel (SAF) dengan diesel konvensional terhadap emisi karbon menggunakan metode Simple Additive Weighting (SAW). Skenario yang dievaluasi mencakup binary blending (diesel dengan satu bahan bakar alternatif) dan ternary blending (kombinasi ketiga bahan bakar) berdasarkan lima kriteria: faktor emisi, kandungan energi, biaya relatif, kelayakan teknis, dan persentase pengurangan emisi. Hasil analisis menunjukkan bahwa ternary blending dengan komposisi 25% LNG + 25% SAF + 50% diesel menempati peringkat tertinggi dengan skor SAW 0,8756, menghasilkan pengurangan emisi sebesar 28,80% dengan biaya relatif 1,312 dan kelayakan teknis 6/10. Ternary blends secara konsisten mengungguli binary blends dengan rata-rata pengurangan emisi 23,27% dibandingkan 11,52%. Penelitian ini memberikan rekomendasi praktis bahwa ternary blending merupakan solusi optimal untuk implementasi near-term yang menyeimbangkan pengurangan emisi signifikan dengan kelayakan ekonomi dan teknis dalam konteks transisi energi Indonesia
