Abstract

ABSTRAK: Pemanfaatan limbah biomassa berupa serbuk kayu mahoni hingga kini masih belum optimal, padahal bahan ini berpotensi besar untuk digunakan sebagai pengisi (filler) dalam campuran aspal beton jenis Asphalt Concrete-Wearing Course (AC-WC). Sebelum diaplikasikan, serbuk kayu tersebut harus dibakar hingga menjadi abu agar memenuhi syarat lolos saringan No. 200 minimal 75% sesuai Spesifikasi Umum Bina Marga 2018 (Revisi 2). Penelitian ini diarahkan untuk menguji kelayakan abu serbuk kayu mahoni sebagai filler pada campuran AC-WC ditinjau dari karakteristik Marshall. Pengujian dilakukan dengan menerapkan kadar filler 2% serta variasi kadar aspal sebesar 5,5%, 6,0%, dan 6,5%. Parameter yang dievaluasi mencakup density, Void in Mix (VIM), Void in Mineral Aggregate (VMA), Void Filled with Bitumen (VFB), stabilitas, flow, Marshall Quotient (MQ), dan Kadar Aspal Optimum (KAO). Hasil laboratorium mencatatkan bahwa abu serbuk kayu mahoni memiliki persentase lolos saringan No. 200 mencapai 98,41%, sehingga lolos kualifikasi sebagai filler. Berdasarkan uji Marshall, didapatkan nilai KAO sebesar 5,51% di mana secara umum penggunaan material ini mampu memenuhi standar karakteristik campuran sesuai regulasi Bina Marga 2018 sehingga sangat berpotensi menjadi bahan alternatif pada perkerasan jalan.

Prior to application, the sawdust must be incinerated into ash to meet the requirement of at least 75% passing the No. 200 sieve, in accordance with the 2018 Bina Marga General Specifications (Revision 2). This study aimed to evaluate the suitability of mahogany sawdust ash as a filler in AC-WC mixtures based on Marshall characteristics. Testing involved a fixed filler content of 2% and varying asphalt contents of 5.5%, 6.0%, and 6.5%. Evaluated parameters included density, Voids in Mix (VIM), Voids in Mineral Aggregate (VMA), Voids Filled with Bitumen (VFB), stability, flow, Marshall Quotient (MQ), and Optimum Asphalt Content (OAC). Laboratory results indicated that the mahogany sawdust ash achieved 98.41% passing the No. 200 sieve, thereby qualifying it for use as a filler. Marshall testing yielded an OAC of 5.51%; overall, the material met the mixture characteristic standards set by the 2018 Bina Marga regulations, demonstrating significant potential as an alternative material for road pavement.
