INTISARI
Seiring dengan meningkatnya kebutuhan material konstruksi yang berkelanjutan, mortar sebagai material yang secara luas digunakan perlu dievaluasi tidak hanya dari aspek mekanik, tetapi juga dampak lingkungannya. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan supplementary cementitious materials (SCMs), yaitu recycled concrete powder (RCP) dan rice husk ash (RHA), terhadap perilaku lentur, dampak lingkungan, dan kinerja keberlanjutan mortar. Variasi campuran yang digunakan meliputi kontrol, 15%RCP, 15%RHA, dan kombinasi 7,5%RCP+RHA. Pengujian beban lentur dilakukan menggunakan metode pembebanan satu titik dengan alat DYE-300S untuk memperoleh kurva beban–waktu secara otomatis. Hasil menunjukkan bahwa penggunaan RHA mampu mempertahankan performa lentur mendekati kontrol, sedangkan RCP cenderung menurunkan kapasitas beban. Dari aspek lingkungan, seluruh variasi SCMs menunjukkan penurunan nilai Global Warming Potential (GWP) dan Embodied Energy (EE), dengan reduksi terbesar pada campuran 15%RHA. Analisis sustainabilitas menunjukkan bahwa nilai eco-performance tertinggi diperoleh pada variasi 15%RHA, yang mengindikasikan efisiensi terbaik antara performa mekanik dan dampak lingkungan. Dengan demikian, pemanfaatan RHA sebagai substitusi semen memberikan kontribusi optimal dalam pengembangan mortar berkelanjutan.
