Fabricating porous material can be done using various raw materials, one of them uses plant-based natural fiber to form composite materials. In this research, the natural fibers of sugarcane waste are synthesized into micro cellulose. Subsequently, the micro cellulose is developed as a filler for the composite ceramic foam. The filler is used to adjust pores characteristics. Morphology characterization was carried out by employing SEM to analyze the structure, pores diameter, and pore distance of the composite. It found that the addition of 1 g of micro cellulose in sizes of 212, 425, and 630 µm into the results: pore diameters of 1.29 × 102, 1.53 × 102 and 1.67 × 102 µm and the distance between the pores is 5.4 × 102, 5.15 × 102 and 4.01 × 102 µm. Moreover, such an addition also affects the composite ceramic foam’s physical properties such as the difference in water content, height/thickness, and density. The absorption performance in composite ceramic foam was assessed by acoustic impedance tubes following the procedure of ISO 10534-2. The results show that the absorption coefficients of each filler size are 63% at 2 kHz for 1 gr filler with 212 micro cellulose. Meanwhile, 68% and 73% around 1.75 kHz and 2.25 kHz are found for 425 and 630 micro cellulose respectively under the same weight.
