Green Distribution Models for Building Material Supply Chains: A Carbon Footprint Optimization Framework
Abstract
Distribusi bahan bangunan merupakan salah satu kontributor utama emisi karbon dalam sektor logistik, terutama karena penggunaan kendaraan berat berbahan bakar fosil dan konsumsi energi intensif di gudang. Penelitian ini bertujuan mengembangkan kerangka kerja distribusi hijau untuk mengoptimalkan jejak karbon dalam rantai pasok PT XYZ(XYZ). Model matematis dirancang untuk mengevaluasi emisi karbon berdasarkan variabel utama seperti jarak tempuh, pemanfaatan kapasitas muatan, konsumsi energi gudang, dan skema offset karbon. Hasil simulasi menunjukkan bahwa kombinasi strategi optimasi rute, peningkatan efisiensi kapasitas muatan, dan transisi energi terbarukan dapat mengurangi total emisi karbon hingga 35% dari baseline. Validasi model dengan data aktual menunjukkan tingkat akurasi yang tinggi, dengan deviasi rata-rata kurang dari 0,3 ton CO₂. Penelitian ini memberikan kontribusi signifikan dalam literatur logistik hijau, menawarkan solusi aplikatif untuk mendukung keberlanjutan operasional distribusi bahan bangunan.
