Palm oil palm is one of the solid waste produced by oil palm plantations every harvest. Chemical analysis of palm oil palm oil pellets showed that there are components of cellulose, hemiscellulose, and lignin that show that palm oil pellets have the opportunity to be further processed into useful and economically valuable products. Palm waste contains cellulose by 34.89%, hemiscellulose by 27.14%, and lignin by 19.87%. The analysis conducted on raw materials includes the analysis of water content and cellulose levels of palm oil palm oil. 46.6% and cellulose levels of 29.2%. In this study quantitative analysis was conducted in the form of cellulose conversion and oxalic acid yield. The largest cellulose conversion was obtained at the use of 70% nitric acid concentration and 80 minutes reaction time of 58.56%.

As one of the solid waste generated by palm oil plantations, Oil Palm Fronds have the potential to be further processed into useful products since the presence of cellulose, hemicellulose and lignin. Hence, the objective of this study was to utilize oil palm fronds in producing oxalic acid through oxidation process using. To achieve the objective, this study assessed conversion of cellulose, yield and quality of oxalic acid produced. Two stages are carried out, namely oxidation and crystallization. Assays on raw materials revealed the cellulose content of 29.2 percent. The largest yield of oxalic acid was 43.31 percent, the highest conversion of cellulose was 58.86 percent. FTIR and melting point analysis were employed in this study. These analyses indicated that the functional groups have reached the standard of oxalic acid with a melting point of 102.1 °C, which showed that the oxalic acid obtained was oxalic acid dehydrate.
