In general, industries that use water in their production process will produce wastewater which usually contains a lot of polluting contaminants. It will affects the surrounding environment by contaminating the water bodies, which will adversely affect the health life of all living beings. Pollution that occurs in the some rivers in Indonesia has begun to raise concern for Indonesian Goverment. Some of the river locations already have heavy poluted status. The pollution is mostly caused by industrial waste and domestic waste along the river. Treatment plants for wastewater effluents are mandatory for any industry which discharges their wastewater effluents into the environment. Information on monitoring the quality of industrial wastewater is very important to be perceived by examining changes in water quality condition that are getting better or worse. It is necessary to develop a system that monitors the condition of industrial wastewater. Industrial wastewater monitoring is a device system that collects real time data. Online monitoring technology is one part that plays an important role in supporting activities to control marine environmental pollution. Real‐time monitoring of wastewater quality remains an unresolved problem to the wastewater treatment industry. One of the problem in most industries in Indonesia is that the operational and performance of wastewater treatment plants (WWTP) are still not optimal, and need to be improved. The application of industrial technology concept 4.0 and automation systems in the industry is expected to improve the WWTP supervision process which has advantages such as reducing down time, reducing consumption of raw materials, reducing the energy used, increasing productivity, improving product quality and making efficient use of resources and processes, so as to reduce industrial operating costs.

The objective of this research is improving the freeness of waste paper stock and paper quality by using the Cellulose Binding Domain (CBD) of endoglucanase Egl-II. CBD has been separated from endoglucanase Egl-II by proteolysis method. CBD has a molecular weight of approximately 21 kD. The produced CBD contained 0.04 mg / mL protein and did not show the total enzyme activity. Waste paper disintegrated using Niagara beater with no load at the consistency of 1.5%. CBD was applied to the refined waste paper fibers with a freeness of 200 mL CSF (Canadian Standard Freeness). The dosages of CBD used for waste paper treatment were 0.2 and 0.3 mg CBD/g of oven-dried pulp. The result shows that this treatment increases the freeness of fibers by 140 mL CSF (70%). CBD also increases the amount of removed water from the fibers from 290 mL to 390 mL and 370 mL, respectively, using the dynamic drainage jar (DDJ) measurement. The cellobiose assay of the waste paper filtrate treated with CBD shows no sugar dissolution, which indicates no cellulose degradation. The tear index of paper produced by treatment with CBD shows insignificant change. The Concora Medium Test (CMT) of paper produced by treatment with CBD has higher tensile index, burst index, and ring crush.Keywords: cellulose-binding domain, endoglucanase Egl-II, freeness improvement, waste paperABSTRAKTujuan penelitian ini adalah untuk memperbaiki freeness dari stok kertas bekas dan mutu lembaran kertas yang dihasilkan dengan menggunakan Cellulose Binding Domain (CBD) dari endoglukanase Egl-II.

A continuous pilot scale study has been conducted to investigate the effectiveness of anaerobic digestion of biological sludge. The sludge has a total solid content of 0.53% - 1.1%, pH of 7.20 to 7.32. Its organic content is about 97 %, The research were conducted in two stages, which are acidification (performed in 3 m3 the Continously Stirred Tank Reactor/CSTR at pH of 5.5 to 6.0) and methanation (performed in 5 m3 the Up Flow Anaerobic Sludge Blanket/UASB reactor at pH 6.5 to 7.0). The retention time (RT) was gradually shortened from 6 days to 1 day for acidification and from 8 days to 2 days for methanation. The results showed that operating the CSTR at the RT of 1 day and the organic loading of 8.23 g Volatile Solid (VS)/m3.day could produce Volatile Fatty Acid (VFA) at an average value of 17.3 g/kg VS.day. Operating the UASB reactor at the RT of 2 days and the organic loading (Chemical Oxygen Demand/COD) of 2.4 kg COD/m3.day could produce biogas at an average value of 66.3 L/day, with an average methane content of 69.9%, methane rate of 0.17 L CH4/g COD reduction or 19.06 L CH4/kg VS. Furthermore, methanation could reduce COD at an average value of 51.2 %, resulting in the effluent average value of COD filtrate and COD total of 210.1 mg/L and 375.2 mg /L, respectively.Keywords: acidification, methanation, CSTR, UASB, biogas ABSTRAKPercobaan digestasi anaerobik lumpur IPAL biologi industri kertas secara kontinyu skala pilot telah dilakukan di industri kertas dengan tujuan mengkaji efektivitas proses digestasi anaerobik dalam mengolah lumpur tersebut.
