Daftar Isi:
- Synthesis of carboxymethylcellulose-g-copoly(acrylic acid)-N,N�- methylene bisacrylamide hydrogel from bagasse cellulose has been done and the use of the hydrogel as a material for enhancing the retention of water and fertilizer in the planting medium of chili pepper has been tested. Bagasse cellulose was obtained from soda process using 5 % (w/v) NaOH solution and then followed by process of bleaching using solution of 5 % (w/v) NaClO. Bagasse cellulose was reacted with natrium monochloroacetate in ethanol media that had been alkalined with 20 % (w/v) NaOH solution. Carboxymethylcellulose (CMC) produced in optimum condition had a viscosity of 51.12 centistokes and the ability to absorb water as much as 80.36 g per g of CMC. Hydrogel was prepared by reacting a solution of CMC with acrylic acid and using MBA as a crosslinking agent and the APS as an initiator. Hydrogel that has the best ability to absorb water was obtained by the addition of MBA as much as 0.056 g. Synthesized hydrogel is used in the planting medium of chili pepper. Hydrogel was planted at a depth of 10 cm. Control plant (A) was planted in a planting medium containing no hydrogel. Chilli plants which were planted in planting medium containing hydrogel subsequently received additional treatment through various watering and fertilizer addition. Variations on the subsequent watering and fertilizer addition began from 100 to 25 % of the watering and fertilizer addition given to the control plant. It was obtained that plants receiving 50 % watering from the control and plants that received 25 % subsequent fertilizer addition (plant H) from the controls had insignificant difference dry weight ratio of fruit and the whole plant.
