Abstract

Oxalic acid is a chemical that is widely used, included for industrial uses such as the manufacture of ink, the manufacture of cellulose synthesis, selluloid manufacture. and it also can be used for reagents. Oxalic acid can be produced by hydrolysis of NaOH with agricultural waste material containing cellulose, including waste rod papaya (Carica papaya), which is still just a waste that has not been used optimally. This study aims to produce oxalic acid (H2C2O4) with utilization waste stem papaya (Carica papaya) by hydrolysis of sodium hydroxide (NaOH), in this research using concentration of NaOH 25% with the comparison between the waste and NaOH 1: 1; 1: 2; 1: 3 and 1: 4, and the duration time of hydrolysis is 45, 60 and 75 minutes. Oxalic acid determination by permanganometry titration. Oxalic acid product research results with variation of papaya stem waste and NaOH 25% is 1: 1, 1: 2, 1: 3 and 1: 4 with hydrolysis time 45 minutes in a row 4,92%; 6,26%; 5,59% dan 3,87%; with hydrolysis time 60 minutes in a row 6,73%; 8,35%; 7,40%; 5,78% and with hydrolysis time 75 minutes in a row 5,49%; 7,37%; 6,29%; 4,94%. Optimum results of oxalic acid from waste products papaya stem with NaOH 25% obtained in a ratio of 1: 2 and hydrolysis of 60 minutes is 8.35%. Keywords : papaya stem, hydrolysis, NaOH, Oxalic Acid
