Abstract

Treatment of pulp bleaching effluent using upflow anaerobic sludge blanket (UASB) and suspended carrier Biofilm (SCB) system 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 activated sludge reactors were observed and analyzed. Settling rate of granular sludge in UASB reactors was also mesured. Effluent of UASB reactor was treated further in Suspended 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%, TSS up to 91% 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 remove COD of 85%, TSS of 73% and AOX of 76%. Sequential UASB and SCB reactor could increase the effectivity of pulp and paper mill wastewater treatment with the removal of dissolved and suspended organic pollutant more than 94%.Key words: AOX, COD, activated sludge, granular sludge, UASB.INTISARI Pengolahan air limbah proses pemutihan pulp dengan system Upflow Anaerobic Sludge Blanket (UASB) dan lumpur aktif termobilisasi telah dilakukan. Reaktor (UASB) dan lumpur aktif termobilisasi masin-masing dioperasikan pada waktu tinggal 12 jam. Larutan micronnutrisi yang mengandung ion-ion logam dalam jumlah sedikit ditambahkan ke dalam umpan reactor UASB untuk mempercepat pertumbuhan lumpur granul. Karakteristik lumpur reaktor UASB diamati dan dianalisa. Kecepatan pengendapan lumpur granul juga diukur. Efluen reactor UASB diolah lebih lanjut dalam reactor lumpur aktif termobilisasi. Parameter COD, TSS dan Adsorbable Organic Halies (AOX) menunjukan bahwa pada waktu tinggal 12 jam, reaktor UASB dapat mereduksi COD 90%, TSS 91% dan AOX 84%. Penambahan larutan mikronutrisi berpengaruh signifikan terhadap pertumbuhan mikroganisme dalam membentukan lumpur granul. Lumpur granul yang terbentuk berdiameter 1-4 mm berwarna hitam kecoklatan memiliki kesepatan 70-120 m/jam. Pengolahan lanjutan dengan sistem lumpur aktif termobilisasi masing-masing dapat mereproduksi COD 85%, TSS 73% dan AOX 76%. Sistem pengolahan air limbah gabungan rector UASB dan lumpur aktif termobilisasi dapat meningkatkan efektifitas pengolahan air limbah industri pulp dan kertas dengan reduksi pencemar organik terlarut dan tersuspesi lebih besar dari 94%.Kata kunci : AOX, COD, lumpur aktif, lumpur granul, UASB

Abstract

Oil spill can contaminate the environment as a consequence of activities related to crud oil exploration, oil refinery, transportation, pipeline leaking, and industrial process. This research related with the characteristics of coir dust as oil sorbent material to remove all from water. Hydrophobycity is an important parameter that determines the effectiveness of the oil sorbent. Some treatments were done in this research to increase tho hydrophobycity of coir dust. Moreover, these treatments were expected to improve oil sorption capacity of coir dust. They are heating and acetylation process. The result showed both of heating and acetylation could increase hydrophobycity and oil sorption capacity onto coir dust.Keywords: coir dust, hydrophobic, oil sorption capacity, sorbent, lignocelluloseINTISARI Tumpahan minyak dapat mencemari lingkungan sebagai konsekuensi dari aktivitas-aktivitas eksplorasi minyak bumi, penghilangan minyak, kecelakaan transportasi, kebocoran pipa, dan proses industri. Penelitian ini berhubungan dengan karakteristik coir dust sebagai bahan penyerap (sorben) minyak untuk menyisihkan cemaran minyak dalam air. Hidrofobisitas (sifat tidak suka air) merupakan parameter penting yang menentukan efektivutas sorben tersebut. Pada penelitian ini dilakukan beberapa perlakuan, baik secara fisik maupun kimia untuk meningkatkan hidrofobisitas coir dust. Perlakuan-perlakuan yang dimaksud adalah pemanasan dan proses asetilasi. Hasil penelitian menunjukan bahwa proses pemanasan dan asetilasi dapat meningkatkan hidrofobisitas dan kapasitas penyerapan minyak pada coir dust.Kata kunci: coir dust, hidrofobik, kapasitas penyerapan minyak, sorben, lignoselulosa.

Abstract

Utilization of paper mill sludge from waste water treatment plant of compost have been proven able to improve the quality of land crop productivity and also uncontaminated the environment. But to produce the compost on a large scale, industry still not yet implemented it because composting process can take time up 3 month. Composting of paper mill sludge by fungi Phanerochaeta chrysosporium, Trichoderma harzianum and Trichoderma reesei have been done at Laboratory scale. The result showed that composting of paper mill sludge by fungi Trichoderma harzianum have the highest cellulose degradation. Composting process for 28 day, can reach the quality standard of compost.Key words: fungi, sludge, cellulose, compostINTISARI Pemanfaatan limbah sludge IPAL industri kertas untuk kompos, telah terbukti berpotensi dalam meningkatkan kualitas tanah dan produktivitas tanaman serta tidak mencemari lingkungan. Namun untuk memproduksi kompos dari limbah sludge secara besar-besaran masih belum dapat diimplementasikan oleh industri, karena proses pengomposan yang memerlukan waktu yang cukup lama sampai sekitar 3 bulan. Pengomposan limbah sludge IPAL industri kertas dengan jamur Phanerochaete chrysosporium, Trichoderma harzinum dan Trichoderma reesai telah dilakukan pada skala Laboratorium. Hasil penelitian menunjukan bahwa jamur Trichoderma harzianum dapat mendegradasi selulosa tertinggi (60,2%) dalam pengomposan limbah sludge industry kertas.Kata kunci : jamur, sludge, selulosa, kompos

Abstract

In this experiment, xylanase was used prior to bleaching, the dosage of xylanase are 0,25; 0,5; 0,75; 1,0; 1,25 kg/ton of chips. The pulps after pretreatment were tested and treated with D0ED1D2 bleaching sequences. The result show that xylanase can decrease kappa number as much as 10.33-11,45. The optimum kappa number (10.33) was obtained by addition xylanase 0,75 kg/ton of chips. Xylanase also 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.Keywords: xylanase, pretreatment, kappa number, bleaching, pulp qualityINTISARIPenelitian ini bertujuan untuk mengetahui pengaruh penggunaan xylanase pada perlakuan awal sebelum pemutihan.

Abstract

In order to review the structure and characteristic of pressure sensitive label (PSL). The examination of 32 PSL. Samples has been carried out. The result of visual examination show that PSL is a laminate, consist of label paper layering by adhesive and coated release-paper. The rest result showed that the basis weight of PSL is 171.3 – 220.7 g/m² with the caliper of 0.1680 – 0.2348 mm. The basis weight is correlated well with caliper and adhesiveness, but it is not with tensile strength, stretch, and tear strength. The ash content is at least 10% which means that paper components of PSL content inorganic filter.Keywords: pressure sensitive label, label paper, release paper, adhesive, basis weightINTISARI Dalam rangka mengkaji struktur dan karakteristik label peka tekanan (LPT), telah dilakukan pemerikasaan visual dan pengujia terhadap 32 contoh LPT yang beredar dipasaran. Hasil pemerikasaan visual menunjukan bahwa LPT adalah produk laminat, tersusun dari kertas label berperekat yang ditutupi kertas pelepas bersalut. Sedangkan data pengujian memperlihatkan bahwa LPT memiliki gramatur 171.3 – 220.7 g/m² dengan ketebalan 0.1680 – 0.2348 mm. Gramatur berkolerasi baik dengan tebal dan daya rekatnya. Tetapi gramatur tidak begitu jelas korelasinya dengan ketahanan tarik, daya regang, dan ketahanan sobek. Kadar abu minimal 10% yang berarti komponen kertas LPT mengandung bahan pengisi anorganik.Kata kunci: label peka tekanan, kertas label, kertas pelepas, pelekat, gramatur
