Abstrak. Telah dibuat genteng komposit polimer berbasis limbah abu boiler kelapa sawit (ABKS) dan serat benang karet ban bekas yang diperkuat oleh aspal melalui teknik konvensional cetak dan tekan. Bahan baku terdiri atas pasir, abu boiler kelapa sawit (ABKS), serat benang ban, aspal, dan resin epoksi dengan variasi komposisi ABKS dan serat benang karet ban adalah sebesar 20%:0%, 18%:2%, 16%:4%, 14%:6%, 12%:8%, dan 10%:10%. Karakterisasi yang dilakukan meliputi: sifat fisis (densitas dan

Hasil tes menunjukkan bahwa sampel dengan komposisi pasir, ABKS, serat benang karet ban, aspal, dan resin epoksi yang optimum sebesar 55%:12%:8%:10%:15% memiliki nilai densitas tertinggi sebesar 1,64 gram/cm 3 , nilai penyerapan air 1,72%, nilai uji impak 77,68 kJ/m 2 , nilai kuat lentur 19,373 MPa, dan suhu DTA (Differential Thermal Analysisis) 360 o C. Hasil ini memenuhi standar SNI untuk genteng yang sudah ada dan dapat dijadikan sebagai alternatif bahan genteng yang harganya terjangkau dan ramah lingkungan. Kata-kata kunci: Abu boiler kelapa sawit (ABKS), genteng komposit polimer, dan serat benang karet ban. Abstract. Polymer composite tile based on boiler ash waste from palm oil industry (ABKS) and fiber from waste tire reinforced by asphalt have been prepared through compression molding techniques. The raw materials consist of sand, ABKS, recycled tire fibers, asphalt, and epoxy resin with variation of ABKS and recycled tire fibers composition by 9 thermal properties (DTA, Differential Thermal Analysis). The test results showed that sample with the optimum composition of sand, ABKS, recycled tire fibers, asphalt, and epoxy resin of 55%: 12%: 8%: 10%: 15% had the highest density value of 1.64 grams/cm 3 , water absorption of 1.72%, impact test value of 77.68 kJ/m 2 , bending strength value of 19.373 MPa, and DTA temperature of 360 ºC. These results meet SNI standards for existing tiles and can be used as an alternative tile materials which is affordable and environmentally friendly Keywords: Boiler ash waste from palm oil industry (ABKS), polymer composite tile, and recycled tire fibers
