"ABSTRAK\r\n\r\n\r\n \r\nKARAKTERISTIK FUNGSIONALITAS DAN MIKROSTRUKTUR\r\nASPAL-KARBOSIL KOMPOSIT \r\n\r\nOleh \r\n\r\nENDAH AYU NINGTIAS \r\n\r\n \r\nSintesis karbosil telah dilakukan dengan bahan dasar silika sekam padi dengan\r\nmetode pirolisis dan metode pencampuran aspal-karbosil yang digunakan yaitu\r\nmetode padatan. Komposit aspal-karbosil dengan massa aspal masing-masing\r\nsampel 0 g; 1,0 g; 1,5 g; 2,0 g; 2,5 g; dan 3,0 g, sedangkan massa karbosil masing-\r\nmasing sampel 10 g; 9 g; 8,5 g; 8 g; 7,5 g; dan 7 g.\r\nP\r\nerubahan gugus fungsi, dan\r\nmikrostruktur komposit aspal-karbosil dipengaruhi oleh variasi perbandingan\r\naspal-karboosil yang digunakan. Hasil FTIR menunjukkan adanya gugus fungsi\r\nO-H, Si-O-Si, Si-O, C-H, dan C=O. Selain itu, hasil analisa SEM menunjukkan\r\nadanya retakan dan gumpalan yang bervariasi pada masing-masing sampel.\r\nKomposisi unsur yang terbentuk sampel aspal-karbosil adalah C, Si, O, dan N.\r\nPenambahan kandungan aspal menyebabkan persentase C meningkat. Hasil uji\r\nfisis menunjukkan bahwa semakin banyak aspal yang ditambahkan maka nilai\r\ndensitas meningkat dan nilai daya serap menurun, selain itu, nilai kekerasan\r\ntertinggi pada sampel dengan perbandingan aspal karbosil 30:70 sebesar 139,97\r\nkgf/mm\r\n2\r\n. Hasil penelitian ini menunjukkan bahwa komposit aspal-karbosil\r\nmempunyai potensi sebagai bahan campuran untuk jalan raya.\r\n\r\nKata kunci: sekam padi, karbosil, aspal, FTIR,SEM, metode pirolisis, aspalkarbosil.\r\n \r\nSynthesis carbosil has been carried out with the basic material of rice husk silica\r\nusing the pyrolysis method and the asphalt-carbosil mixing method which used\r\nwas the solids method. Asphalt-carbosil composites with asphalt mass for each\r\nsamples are; 0 g; 1.0 g; 1.5 g; 2.0 g; 2.5 g; and 3.0 g, while the carboxyl mass of\r\neach samples are 10 g; 9 g; 8.5 g; 8 g; 7.5 g; and 7 g. Changes of the functional\r\ngroups and the microstructure of the asphalt-carbosil composite were affected by\r\nthe variation of the asphalt-carbosil ratio. The FTIR results shows the presence of\r\nfunctional groups O-H, Si-O-Si, Si-O, C-H, and C=O. In addition, the results of\r\nthe SEM analysis shows that there are various cracks and lumps in each sample.\r\nThe elemental compositions of the asphalt-carbosil samples are C, Si, O, and N.\r\nThe addition of asphalt content causes the increasing of C percentage. The results\r\nof the physical test shows that the more asphalt was added, the density value\r\nincreases and the absorption value decreases, in addition, the highest hardness\r\nvalue in the sample with a ratio of 30:70 carbosil asphalt is 139.97 kgf/mm\r\n. The\r\nresults of this study indicates that the asphalt-carbosil composite has the potential\r\nas a mixture for highways.\r\n\r\nKeywords: rice husk, carbosil, asphalt, FTIR, SEM, pyrolysis method, asphaltcarbosil.\r\n\r\n"^^ .
