<![CDATA[Abstrak Penelitian ini bertujuan menganalisis pengaruh penambahan tepung jagung terhadap stabilitas dan permeabilitas campuran aspal porus. Penelitian menggunakan metode eksperimental dengan kadar aspal optimum (KAO) sebesar 4,5% dan variasi tepung jagung sebesar 0–2,5%. Hasil penelitian menunjukkan bahwa stabilitas tertinggi sebesar 821 kg diperoleh pada variasi 2,5%, namun nilai Void in Mix (VIM) tidak memenuhi standar AAPA (2004). Variasi 2,0% menghasilkan stabilitas sebesar 807 kg dengan nilai VIM 18,05% yang memenuhi standar, sehingga direkomendasikan sebagai campuran aspal modifikasi. Variasi 0,5% memberikan kinerja permeabilitas terbaik dengan waktu aliran 10,67 detik/liter dan koefisien permeabilitas 0,49 cm/s. Secara keseluruhan, seluruh variasi memenuhi persyaratan permeabilitas menurut AAPA (2004). Kata kunci: aspal porus, tepung jagung, stabilitas, permeabilitas, VIM. Abstract porous asphalt mixtures. An experimental method was employed, with an optimum asphalt content (OAC) of 4.5%. Corn starch extract was added at 0%, 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%. The results indicated that corn starch extract improved the performance of porous asphalt mixtures. The highest stability (821 kg) was obtained at 2.5%, although its Void in Mix (VIM) did not meet the AAPA (2004) specification. The 2.0% mixture achieved a stability of 807 kg and a VIM of 18.05%, satisfying the AAPA (2004) standard. Therefore, the addition of 0.5–2.0% corn starch extract is recommended for modified porous asphalt. The 0.5% mixture showed the best permeability performance, with the shortest flow time (10.67 s/L) and a permeability coefficient of 0.49 cm/s. Overall, all mixtures met the permeability requirements of the AAPA (2004) standard. Keywords: porous asphalt, corn starch, stability, permeability, VIM.]]>
