This study aims to apply pineapple leaves as a base substance in the preparation of dielectric materials and to analyze the important factors in pineapple leaves preparation as dielectric materials. Dielectric materials are basically insulators and are poor electrical conductors. They are commonly used for energy storage in capacitors. The investigated factors include the pineapple leaf powder mass (3 and 5 g), the ratio of pineapple leaves to distilled water, PL: DW (1:10 and 1:15), the boiling time (30 and 50 min), and the heating option (yes or no). The cellulose content was analyzed using the Kurschner-Hanack method, and the permittivity value was obtained through an Agilent Vector Network Analyzer (VNA). The experimental setup was designed by the Design-Expert software, and the data were analyzed accordingly based on the two-level factorial design (TLFD). Based on the analysis, the best condition was suggested at 3 g of pineapple leaf powder mass, 1:10 of PL: DW, 49.24 min of boiling time, and a heated sample. At this condition, the percentage of cellulose content and permittivity values were up to 59.25% and 2.8876, respectively. The obtained p -value of the cellulose content and permittivity values of 0.0035 and 0.0047 show that the chosen model was significant. The R 2 of 0.9856 and 0.9412 explained the well-fitted model for cellulose content and permittivity value. Hence, exploring dielectric material production using pineapple leaves could be another option to minimize pollution while turning waste into a valuable item. Graphical abstract
