Kesan faktor-faktor pemulpaan soda-AQ ke atas sifat-sifat pulpa dan kertas tandan buah kosong kelapa sawit telah dikaji menggunakan Metodologi Permukaan Sambutan berasaskan Rekabentuk Komposit Berpusat. Faktorfaktor pemulpaan yang dikaji ialah alkali (A), suhu pemulpaan (T) dan masa pemulpaan (t), dengan julat masing-masing antara 20 - 30%, 160 - 180°C dan 60 - 120 minit. Keputusan sifat-sifat pulpa yang terdiri daripada hasil keseluruhan, hasil penskrinan, nombor Kappa dan kelikatan didapati berada dalam julat 35.37 - 58.87%, 30.37 - 56.07%, 6 - 16 dan 5.43 - 16.02 cP. Manakala sifat-sifat kertas seperti indeks tensil, indeks koyakan, indeks pecahan, ketahanan lipatan, kekuatan tensil zero-span, kecerahan dan kelegapan pula masing-masing berjulat 14.95 - 30.95 N.m/g, 5.09 - 9.22 mN.m2/g, 4.17 - 5.80 kPa.m2/g, 0.67 - 2.36 10glO, 36.18 - 57.00 N, 39.58 - 56.40% dan 94.92 - 98.26%. Influence of soda-AQ pulping conditions on pulp and paper properties of oil palm empty fruit bunches were studied using Response Surface Methodology based on Central Composite Design. Alkali (A), pulping temperature (T) and pulping time (t) were among pulping factors that had been studied with their range between 20 - 30%, 160 - 180°C and 60 - 120 minutes respectively. Pulps properties evaluated based on total yield, screened yield, Kappa number and viscosity were in the range within 35.37 -58.87%, 30.37 - 56.07%, 6 - 16 and 5.43 - 16.02 cP respectively. On the other hand, mechanical properties of handsheets produced namely tensile index, tearing index, bursting index, folding endurance, zero-span tensile strength and its optical properties, brightness and opacity ranged between 14.95 - 30.95 N.m/g, 5.09 - 9.22 mN.m2/g, 4.17 - 5.80 kPa.m2/g, 0.67 - 2.36 log10, 36.18 - 57.00 N, 39.58 - 56.40% and 94.92 - 98.26% respectively.
