"Performa ekspor industri pulp dan kertas tidak terlepas dari kontribusi perusahaanperusahaan pulp dan krtas yang memutuskan untuk menjual sebagian hasil produksinya di pasar ekspor. Penelitian ini dimaksudkan untuk melihat variabel-variabel apa saja yang mempengaruhi performa ekspor industri pulp dan kertas Indonesia. Dalam hal ini performa ekspor difokuskan pada kecenderungan perusahaan untuk mengekspor dan kemudian melihat besarnya proporsi output yang diekspor oleh perusahaan yang telah sukses dalam mengekspor. Secara empiris, penelitian ini menunjukkan bahwa tingkat kesuksessan perusahaan untuk mengekspor dipengaruhi secara positif oleh produktivitas, rasio input yang diimpor, dan kepemilikan modal asing, dan dipengaruhi secara negatif oleh lokasi. Sedangkan proporsi output yang diekspor oleh eksportir dipengaruhi secara negatif oleh produktivitas, umur perusahaan, rasio input yang diimpor, dan lokasi. Penelitian ini menggunakan metode regresi probit untuk model kecenderungan firm?s propensity to export dan OLS (Ordinary Least Square) untuk model firm?s export intensity."

"In this experiment, xylanase was used prior to bleaching. The dosages of xylanase are 0.25; 0,5; 0,75; 1;1,25 kg/ton of chips. The pulps after pretreatment were tested and treated with D0ED1D2 bleaching sequences. The result shoew that xylanase can decreasekappa number as much as 10.33-11.45. The optinum kappa number (10.33) was obtaidned by addition xylanase 0.75 kg/ton of chips. Xylanase also increases increase bleachability of pulp and decrease dirt on pulp, from initial brightness 82.4 % ISO to 83.10 % ISO. While dirt from 9.5 mm2/m was decrease to 7-8 mm2/m2. Xylanase was able to decrease dichloromethane extractive content in bleached pulp as much as 0.06-0.14 point. Xylanase also increases bleaching selectivity, as physical strength of pulp tend to increase."

"The organic complex compound contained in pulp and paper's mill wastewater such as lignin and cellulose is difficult to be degraded, that causes low biodegradability of aerobic microorganism in high organic loading rate actinated sludge system. Xylanase and cellulase aplication experiment on activated sludge system process had taken in batch process, aimed to enchance organic complex com[pound's biodegradation effectivity. The experiment used a combination of pulping's wastewater (black liquor) and paper's mill waste to have COD+1500 mg/L. The treatment variations are: activated sludge concentrations (MLSS), enzyme dosages, and residence time. Activated sludge concentrations are MLSS 0, 2000, and 4000 mg/L, xylanase and cellulase's dosages are control, 50 and 100 ppm. and residence time are 12, 18, and 24 hours. This experiment yield highest COD reduction of 35,55% in activated sludge with 50 ppm xylanase application, where 50,96% reached with 100 ppm cellulase application, both occurred in MLSS 2000 mg/L and residence time 24 hours. Compared with control whose only reached COD reduction of 31,12 %, xylanase enchanced the reduction 4,43 % when cellulase enhanced 19,84%."

"Treatment of pulp bleaching effluent using Upflow Anaerobic Sludge Blanket (UASB) and Suspended Carrier Biofilm (SCB) systems have been carried out. Upflow Anaerobic Sludge Blanket (UASB) and Suspended Carrier Biofilm (SCB) reactors were run on the Hydraulic. Retention Time (HRT) of 12 hours, respectively. Micronutrient solution containing some traces elements was added into feed wastewater of UASB reactor to accelerate the growth of granular sludge. Sludge characteristics of UASB and activeted sludge reactors were observed and analyzed. Settling rate of granular reactor was also measured. Effluent of UASB reactor was treated further in Susoended Carrier Biofilm (SCB) reactor. Concentration of COD, TSS and AOX parameters both influent and effluent of UASB reactor as well as suspended carrier biofilm (SCB) reactor were analyzed. Result revealed that UASB reactor run on the Hydraulic Retention Time (HRT) of 12 hours could remove COD up to 90 % and AOX up to 84 %. Addition of micronutrient solution has accelerated the growth of granular sludge. Dark-brownesh color of granular sludge with the diameter of 1-4 mm having settling rate of 70-120 m/hr has been formed. SCB reactor as post-treatment could remover COD of 85%, TSS of 73 % and AOX of 76%. Sequential UASB and SCB reactor could increase the effectivity of pulp and paper mill wastewatertreatment with the removal of dissolved and suspended organic pollutant more than 94%."
