Solms paper process whilst the increasing of paper pulp by the agriculture wastes as pineapple and banana leaves. The experimental started preparing the paper pulp using NaOH 10 g/l at 100oC for 3 hours. Then, the paper pulp was bleaching with H2O2 5 g/l at 90oC for 30 minutes. The paper was used for packtech what the optimum ratio were 70% Eichhornia crassipes (Mart.) Solms, 10% pineapple leaf, and 20% banana leaf. The paper properties were increased by distributing agent as Acramin 5 g/l and improving the paper strength with 5%w/v residual activated carbon water. The product had an equivalent quality as craft paper type KI. It has 0.537 mm in thickness, 35.4 kN/m2bursting strength, tear strength 356 mN, and 185 gram in weight. The paper was good at box set for the generally products.
