Abstract

Solid waste of paper mill hydrapulper reject (HR) has a relatively high plastic content, with around 45-49% composition of the total HR. About 99% of the plastic has the catagory of High Density Polyethylene (HDPE). HDPE is a type of Polyethylene (PE) plastic which has high recyclability and may be reformed at high temperature. This study tries to discribe the potential of producing particleboards derived from HR using a hot-press method. Molded HR was being hot-pressed at a presssure of 25 kgf/cm2for 5 – 15 minutes of residence time, with a variation of of the amount of HR from 150-500 gram, and variations in hot-press temperature of 150-180°C. The resulting product is then analyzed for parameters of moisture content, density, water absorption, thickness swelling, and internal bond compared to SNI 03-2105-2006 and JIS A 5908-2003. The results showed that most of the samples were relatively accepted to the SNI. The best results are obtained at HR weight of 250 gram with 165 and 180°C pressing temperature, and pressing time more than 10 minutes. The addition of HDPE pellets shows an increment of density and decrement of moisture content of particleboard, while the addition of MA shows some decrements of moisture content and water absoption of particleboard.

Abstract

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.

Abstract

As the effluent quality standards for industrial wastewater are becoming more stringent, it is important for the industry to improve their wastewater treatment efficiency. The research about potential of cellulase application in the activated sludge process has been done. Theoritically, the addition of cellulase was required to support the activity of microorganism on the activated sludge. Since cellulose is the major organic pollutant component in the wastewater, it was expected that cellulase addition could improve the performance of activated sludge process. The experiments were conducted in a continuous process and consisted of two treatments which were with and without activated sludge at about 2400 mg MLVSS/L. The variations in each treatment were the enzyme dosages of 0; 0.2; 0.5; and 0.7 unit/g COD, and the residence time of 4, 8, 12, and 24 hours. The experiment result showed that the addition of cellulase can increase COD and BOD reduction compared to the treatment without enzymes. The highest COD reduction increment was 7.9% at the enzyme dosage of 0.2 unit/g COD and the residence time of 4 hours, while the highest BOD reduction increment was 14.6% at the same enzyme dosage and residence time. In conclusion, celullase application can be combined with the activated sludge process which will be effective in the high load organic wastewater. ABSTRAKDengan semakin ketatnya baku mutu air limbah, peningkatan efisiensi dalam pengolahan limbah menjadi sangat penting bagi industri. Penelitian ini dilakukan untuk mengetahui potensi selulase dan pengaruh laju pembebanan pada efektifitas pengolahan air limbah kertas sistem lumpur aktif. Secara teori, penambahan selulase diperlukan untuk membantu aktivitas mikroorganisme lumpur aktif. Dengan adanya kandungan selulosa sebagai komponen utama pencemar organik dalam air limbah, penambahan selulase diharapkan dapat meningkatkan kinerja proses lumpur aktif. Percobaan dilakukan dengan proses kontinyu yang terdiri dari dua perlakuan, yaitu tanpa dan dengan lumpur aktif pada MLVSS sekitar 2400 mg/L. Variasi pada setiap perlakuan berupa variasi dosis selulase (0; 0,2; 0,5; dan 0,7 unit/g COD) dan variasi laju pembebanan dengan mengatur waktu tinggal 4, 8, 12, dan 24 jam. Hasil percobaan menunjukkan bahwa perlakuan lumpur aktif dengan penambahan selulase dapat menghasilkan peningkatan reduksi COD dan BOD bila dibandingkan perlakuan tanpa menggunakan selulase. Peningkatan reduksi COD tertinggi mencapai 7,9% dengan perlakuan selulase dosis 0,2 unit/g COD dan waktu tinggal 4 jam, sedangkan peningkatan reduksi BOD tertinggi mencapai 14,6%. Perlakuan selulase dapat dikombinasikan dengan proses lumpur aktif yang berjalan efektif pada waktu tinggal yang lebih singkat atau pada beban tinggi.Kata kunci: selulase, lumpur aktif, chemical oxygen demand, biological oxygen demand

Abstract

Pertumbuhan industri yang pesat menyebabkan masalah emisi gas rumah kaca. Kegiatan co-benefit peningkatan efisiensi boiler batubara telah dilakukan di industri kertas dalam proyek “Co-benefit Indonesia Tahun 2018” dari Kementerian Lingkungan Hidup Jepang dengan tujuan melakukan identifikasi langkah-langkah yang terkait dengan konservasi energi dan penurunan polutan emisi boiler industri berbahan bakar batubara dan cara melakukannya. Identifikasi meliputi analisis efisiensi termal boiler, pengukuran kadar air batubara, pengukuran kualitas air umpan boiler, air blowdown, dan kondensat, pemeriksaan insulasi panas, pengaturan rasio udara pembakaran, dan pengendalian operasi multi boiler. Berbagai kehilangan panas dianalisis dan beberapa rekomendasi diberikan untuk implementasi di pabrik sehingga efisiensi boiler dapat ditingkatkan. Beberapa masalah yang perlu diperbaiki untuk konservasi energi meliputi penggunaan batubara dengan kadar air tinggi, rasio udara pembakaran tinggi, konduktivitas air umpan tinggi menyebabkan rasio blowdown tinggi, tidak dilakukan insulasi pada mesin produksi yang relatif tua, dan pengoperasian beberapa boiler dengan efisiensi rendah. Potensi perbaikan melalui penyesuaian kadar air batubara, perbaikan rasio udara pembakaran, optimalisasi rasio blowdown, pemulihan air kondensat, pemasangan insulasi, dan kontrol multi boiler secara teori menghasilkan reduksi konsumsi batubara 16.445 ton/tahun atau 48,63%, dan reduksi CO2 sebesar 19.589 tCO2/tahun dengan estimasi penghematan biaya Rp 12 milyar/tahun. Kata kunci: co-benefit, industri kertas, boiler, batubara, emisi.Case Study of Co-Benefit Project Improvement of Coal Boiler Efficiency in The Paper IndustryABSTRACT Industrial rapid growth has caused greenhouse gas emissions problems. Co-benefit activities to improve the efficiency of coal boilers have been carried out in paper industry in the project of “Co-benefit Indonesia FY 2018” from the Japan Ministry of Environment aimed at identifying required steps to save energy and reduction of pollutant emission from the coal-fired industrial boilers and how to achieve it. Identification include analysis of boiler thermal efficiency, coal moisture content measurement, boiler feed water, blowdown water and condensate quality measurement, heat insulation examination, combustion air ratio management, and control of multiple boiler operations. Various heat losses have been analyzed and some recommendations have been proposed to be implemented by factory management to improve boiler efficiency. There are several issues that need to be addressed for energy conservation, namely: high water content coal utilization, high combustion air ratio, high conductivity feed water which causes high blowdown ratios, no insulation on relatively old production machines, and operational of several low efficiency boilers. The results of the co-benefit identification indicated that the potential for corrective action by adjusting the coal water content, improving the combustion air ratio, optimizing the blowdown ratio, recovering condensate water, installing insulation, and controlling multiple boilers theoretically can result coal consumption reduction of 16,445 tons/year or 48.63%, and CO2 reduction of 19,589 tCO2/year with an estimated cost savings of Rp 12 billion/year.
