Abstract

Research of fed batch saccharification using paper mill primary sludge from Waste Water Treatment Plant (WWTP) has been conducted. The research was conducted in several stages i.e. sludge characterization, determining optimum dosage of cellulase and glucosidase through batch saccharification, and continued with fed batch saccharification. The characterization was performed on 3 primary sludge type from 3 paper mill, which are print paper mill with virgin pulp raw material, paper tissue mill with virgin pulp raw material and core board mill with waste paper raw material. The characterization results showed that the sludge derived from the tissue paper mill with virgin pulp raw material has the highest content of cellulose which is 47.06%, this sludge was used as further research material. The initial trial of batch saccharification at 6% w/w and temperature of 60oC gave optimum dosage of cellulase 9 FPU/g cellulose and β-glucosidase 80 IU/g cellulose with reducing sugar 20.01 g/L and a saccharification efficiency of 63.84%. Fed batch saccharification was performed on tissue paper mill sludge at cellulase and glucosidase enzyme doses respectively 9 FPU/g cellulose and 80 IU/g, temperature 60°C and initial pH of 4 with two variables, which are cumulative solid content (10%, 14%, and 18% w/v) and feed enzyme system (at the beginning and in step). The best results were obtained at fed batch sakarifikasi with gradual enzyme feeding at 14% solids content resulting in reducing sugar 43.899 g/L and efficiency 60.03%.

Abstract

The kenaf taken from Malang-East Java was four to five months old and used as the raw material of dissolving pulp. Morphology and chemicals content of kenaf was analyzed based on Indonesian National Standard (SNI). Kenaf fibre has the fibre length average of 2.59 mm for stem and 3.63 mm for bast and it is classified on the long fiber, fibre length > 1.60 mm. It contains alpha cellulose in the amount of 45.45% for bast and 39.46% for stem. Kenaf was cut with the length of 3 to 5 cm to make chips. Before cooking, pre-hydrolyzed using water and dilute acid (0.4% H2SO4) was done to remove pentosan (hemicellulose) by soaking chips in water and 0.4% H2SO4 in the ratio of 1 : 5 at temperature of 135oC for 2 hours. The results was mixed with cooking liquor which contains Active Alkali (AA) of 16% and Sulfidity (S) of 28%. Ratio of raw material and cooking liquor was 1 : 5 at temperature of 160oC for 3 hours. Bleaching process was done in the five stages consisted of X0D0E0D1D2 (Xylanase, Oxygen delignification, Chlorine Dioxide, Oxygen Ectraction, Chlorine Dioxide 1st, Chlorine Dioxide 2nd). Bleaching process in the stage of X use xylanase enzyme (bio-bleaching). Every stage was washed with hot soft water up to neutral pH. Dissolving pulp was analyzed for brightness, alpha cellulose content and other chemicals content. Pulp viscosity is very high, which means that the pulp bleaching process is not much cause degraded cellulose Keywords: bio-bleaching, dissolving pulp, pre-hydrolyzed, kenaf, xylanase  ABSTRAKKenaf berasal dari daerah Jawa Timur Malang - berusia empat sampai lima bulan dan digunakan sebagai bahan baku dissolving pulp. Morfologi dan komponen kimia kenaf dianalisis berdasarkan Standar Nasional Indonesia (SNI). Serat kenaf memiliki panjang serat rata-rata 2,59 mm untuk batang dan 3,63 mm untuk kulit pohon, termasuk kedalam kelompok serat panjang dengan panjang serat > 1,60 mm. Kenaf mengandung alpha selulosa sebesar 45,45% untuk kulit dan 39,46% untuk batang. Kenaf dipotong-potong dengan panjang 3 sampai dengan 5 cm. Sebelum pemasakan, dilakukan prahidrolisa menggunakan air dan asam encer (0,4% H2SO4) untuk melunakkan serpih kenaf dan membuat ikatan pentosan (hemiselulosa) menjadi lemah, dengan merendamnya dalam air dan 0,4% H2SO4 dengan rasio 1 : 5 pada suhu 135oC selama 2 jam. Selanjutnya dilakukan pemasakan dengan proses kraft menggunakan Alkali Aktif (AA) sebesar 16% dan sulfiditas (S) sebesar 28%. Rasio bahan baku dan larutan pemasak adalah 1 : 5 pada suhu 160oC selama 3 jam. Proses pemutihan pulp dilakukan dalam lima tahap terdiri dari X0D0E0D1D2 (Xilanase, Oksigen delignifikasi, Klorin dioksida, Oksigen Ekstraksi, Klorin dioksida 1, Klorin dioksida 2). Proses pemutihan pada tahap X menggunakan enzim xilanase yang dikenal dengan bio–bleaching. Setiap tahap dicuci dengan air panas sampai bersih. Dissolving pulp yang diperoleh dianalisis derajat cerah, kadar selulosa alfa dan komponen kimia lainnya sesuai SNI. Dissolving pulp mempunyai viskositas yang sangat tinggi, ini berarti bahwa proses pemutihan pulp tidak banyak menyebabkan terjadinya degradasi selulosa.Kata kunci: bio-bleaching, dissolving pulp, prehidrolisa, kenaf, xilanase

Abstract

This research was to study the pretreatment effect of mixed culture fungi (T.versicolor, P.ostreatus and P.crysosporium) of betung bamboo on quality of pulp kraft and to determine the effect of pretreatment compared to monoculture. Bamboo chips were inoculated at room temperature and analysed by SEM. Bamboo chips was cooked by kraft process and analysed its properties i.e yield, kappa number, delignification selectivity, freeness and pulp brightness. Results showed that mixed culture pretreatment of T.versicolor, P.ostreatus, dan P.crysosporium gave better pulp quality compared to monoculture. Each fungi treatment gives different effect on pulp properties. Pulp yield was increased which compare to without fungi treatment. If three fungi species were mixed, it showed little positive effect on pulp properties. Mixed culture pretreatment can increased freeness. Meanwhile, pulp yield and delignification selectivity were increased, and kappa number was decreased. Fungi pretreatment can increase pulp brightness level compare to control. SEM image indicated a degradation of bamboo cell wall caused by fungi activity. The longer incubation time reduced kappa number and improved pulp yield and delignification selectivity. The highest pulp quality is by a co-culturing T.versicolor and P.crysosoporium on 30 days incubation.Key words : white rot fungi, mixed culture, kraft pulping, betung bamboo, pulp quality INTISARIPenelitian ini dilakukan untuk mempelajari pengaruh perlakuan kultur campur jamur T. versicolor, P.ostreatus dan P. crysosporium pada bambu betung dengan proses pemasakan kraft terhadap kualitas pulp. Selain itu, untuk mengetahui perbedaan pengaruhnya terhadap kualitas pulp yang dihasilkan dari perlakuan kultur tunggal. Bambu diinokulasi pada suhu ruang dan dianalisa dengan SEM. Bambu dimasak dengan proses kraft dan dianalisa kualitas pulp berupa rendemen pulp, bilangan kappa, selektifitas delignifikasi, derajat giling, dan derajat putih. Hasil penelitian menunjukan bahwa perlakuan awal kultur campur T.versicolor, P.ostreatus, dan P.crysosporiummemberikan kualitas pulp yang lebih baik dibandingkan kultur tunggal ditinjau dari bilangan kappa, selektifitas delignifikasi dan rendemen. Masing-masing kombinasi perlakuan jamur memberikan respon yang berbeda. Terjadi peningkatan rendemen dibandingkan dengan kontrol. Jika ketiga spesies jamur dicampur maka kurang berpengaruh positif terhadap kualitas pulp. Perlakuan kultur campur menyebabkan pulp lebih kasar yaitu terjadi peningkatan derajat giling. Sedangkan rendemen dan selektifitas delignifikasi meningkat, serta bilangan kappa menurun. Perlakuan jamur meningkatkan derajat giling pulp dibandingkan kontrol. Pencitraan SEM menunjukkan perlakuan kultur campur menyebabkan degradasi dinding sel bambu. Bertambahnya lama inkubasi menyebabkan penurunan bilangan kappa, peningkatan selektifitas delignifikasi dan rendemen. Perlakuan terbaik adalah inokulasi secara bersamaan T.versicolor and P.crysosoporium dengan lama inkubasi 30 hari.Kata kunci : jamur pelapuk putih, kultur campur, kraft pulping, bambu betung, kualitas pulp

Abstract

Ground Calcium Carbonate (GCC) as the filler required in paper making that is intended to reduce production costs thus providing a profit opportunity for the paper industry. However the usage of GCC affected decreasing of paper strength and effectiveness of sizing process. In order to reduce the negative effect, this research has been conducted through the modification of filler using Tamarind Kernel Powder (TKP) which is a natural polymer obtained from local tamarind seeds. The results of high performance liquid chromatography (HPLC) analysis, showed that TKP contained 64-68%   xylose, glucose, maltose and arabinose. Filler modification was conducted with mixing the TKP into CaCO3 and addition of cationic polyacrylamide and sodium polyphosphate dispersant at composition ratio of 100: 0.4 : 0.1: 1.0. Filler application with added the retention aid of cationic polyacrylamide 0.1%, resulted the filler retention value on sheet of 26.9 %. The modified filler shows an increase in filler stability and is easy to form emulsions when compared to commercial fillers. Modification of GCC filler with higher number of TKP usage gives increased filler retention value on sheets, improved sheet formation properties and optical properties.ABSTRAKGround Calcium Carbonat (GCC) sebagai bahan pengisi (filler) dalam pembuatan kertas untuk mengurangi biaya produksi sehingga memberikan peluang keuntungan bagi industri kertas, namun peningkatan jumlah GCC dapat berpengaruh pada menurunnya kekuatan kertas dan efektivitas proses pendarihan. Untuk mengurangi pengaruh negatif telah dilakukan penelitian modifikasi filler menggunakan Tamarind Kernel Powder (TKP) yang merupakan polimer alami dari bahan lokal biji asam jawa. Hasil analisis kromatografi cair kinerja tinggi (KCKT) menunjukkan bahwa TKP mengandung silosa 64-68 %, glukosa, maltosa, dan arabinosa. Modifikasi filler dilakukan  dengan  mencampurkan TKP ke dalam  CaCO3 dengan  penambahan  poliakrilamida kationik dan dispersan natrium polifosfat pada komposisi 100 : 0,4 : 0,1 : 1,0. Aplikasi filler dengan penambahan zat peretensi 0,1 % poliakrilamida kationik diperoleh nilai retensi filler pada lembaran 26,9 %. Filler yang termodifikasi menunjukkan peningkatan stabilitas filler dan mudah membentuk emulsi jika dibandingkan dengan filler komersial. Modifikasi filler GCC dengan jumlah TKP yang lebih tinggi memberikan peningkatan nilai retensi filler pada lembaran, peningkatan formasi dan sifat optik lembaran.

Abstract

Kraft pulp mills generate large amounts of sludge cake with typical calorific value of 24 MJ/kg (dry and ash-free basis). Sludge cake could be utilized as an alternative energy through gasification to produce medium gaseous fuel. Sludge cake has a high moisture content and low dewaterability, probably due to biomass from the microbial growth in the wastewater treatment by activated sludge. These problems could be overcome by the addition of filtration aid utilizing biomass waste from pulp mill and dewatering processes by TAMD method. Drying was continued by utilizing hot flue gas from the boiler or lime kiln. Steam gasification of sludge cake by allothermal model could produce a gaseous fuel with a calorific value of 11 MJ/Nm3. Allothermal gasification model of two reactors was able for handling sludge cake with a moisture content of <55%, but produce gas with a high tar content.Gasification or combustion of sludge cake on this model should be performed at temperatures >1200°C to prevent slagging and fouling problem. In contrast, allothermal gasification model of three reactors could produce gas with a low tar content. Heat of gasification reaction might be supplied from thecombustion of volatile gas. Pyrolysis could be performed at temperatures <500oC to permit adequateheat supply for gasification and high char yield. Substitution of natural gas with producer gas need topay attention to the redesign of the combustion process associated with the lower heat of combustion.Keywords: sludge cake, dewatering, gasification, steam, CO2, medium gaseous fuelABSTRAK Pabrik pulp kraft menghasilkan sludge cake dalam jumlah besar dengan nilai kalor tipikal 20 MJ/kg (dasar kering dan bebas abu). Sludge cake dapat dimanfaatkan sebagai energi alternatif melalui gasifikasi untuk menghasilkan bahan bakar gas medium. Sludge cake memiliki kadar air tinggi dan dewaterability rendah, disebabkan adanya biomassa hasil pertumbuhan mikroba pengolahan air limbahsecara lumpur aktif. Kendala ini diatasi dengan penambahan media bantu  filtrasi memanfaatkan limbah biomassa pabrik pulp dan proses dewatering dengan metode TAMD. Pengeringan dilanjutkan dengan memanfaatkan gas panas dari boiler atau lime kiln. Proses gasifikasi-kukus allothermal terhadap sludge cake dapat menghasilkan gas bakar dengan nilai kalor 11 MJ/Nm3. Gasifikasi allothermal model dua reaktor mampu menangani sludge cake dengan kadar air <55%, namun menghasilkan gas dengan kadar tar yang tinggi. Gasifikasi atau pembakaran sludge cake pada model ini sebaiknya dilakukan pada suhu di bawah 1200oC untuk menghindari terjadinya slagging dan fouling. Sebaliknya, gasifikasi allothermal model tiga reaktor dapat menghasilkan gas dengan kadar tar rendah. Panas reaksi gasifikasi mungkin dapat dipenuhi dari pembakaran gas volatil hasil pirolisis. Pirolisis dapat dilakukan pada suhu <500ºC dengan mempertimbangkan kecukupan suplai panas gasifikasi dan yield arang tinggi. Penggantian gas bumi dengan gas produser perlu memperhatikan redesign proses pembakaran terkait dengan panas pembakaran yang lebih rendah.Kata kunci: sludge cake, dewatering, gasifikasi, kukus, CO2, bahan bakar gas kalor medium

Abstract

There are some trends happen in relation to corrugating industries, namely the substitution of liner by fluting medium for certain corrugated container which do not need strength tightly. Due to the tremendous usage of this box type, the requirements of stacking strength (BCT) of the box neglected following by the ignoring of ring crush test (RCT) value for liner and medium. The RCT easily neglected due to the facts that this parameter do not successful to correlate well with the BCT. The results of testing analysis for a number of liner and medium samples coming from Indonesian paper mill supported these facts. The RCT is not a material property of liner and medium, the value depends on basis weight and manufacturing processes. Short-span Compression Test (SCT) was proven covering the weaknesses of RCT, therefore the SCT is proposed to replace the RCT.Keywords: RCT, SCT, material-property, liner, medium fluting  ABSTRAK Telah terjadi kecenderungan substitusi kertas lainer oleh kertas medium di industri kotak karton gelombang untuk keperluan tertentu yang tidak memerlukan kekuatan secara ketat. Tetapi karena penggunaan jenis kotak seperti ini sangat banyak, maka persyaratan ketahanan tumpuk (BCT) kotak menjadi terabaikan diikuti dengan terbaikannya nilai ketahanan tekan lingkar (RCT) lainer dan medium. Mudahnya RCT diabaikan karena fakta menunjukkan bahwa RCT tidak mampu memprediksi BCT dengan baik. Hasil analisis pengujian kertas lainer dan medium dari pabrik-pabrik di Indonesia mendukung fakta tersebut. RCT bukan karakter bahan lainer dan medium, nilainya sangat tergantung pada gramatur dan proses manufaktur. Sementara itu parameter SCT telah terbukti mampu mengatasi kekurangan RCT, maka diusulkan agar SCT menjadi parameter baru pengganti RCT.Kata kunci: RCT, SCT, karakter-bahan, lainer, medium

Abstract

The influence of the sludge waste compost of paper mill wastewater treatment plant (WWTP) to vegetation and soil percolate water has been investigated. Composting process was done for 45 days by using sawdust as mixed material in the amount of 20% v/v. Compost affect was done to corn vegetation with some dose variation, and manure from chicken with the same dose was also done for the comparator. To know the possibilities of the compost substances wash out into soil and carry over into subsoil water, it was done by using two lysimeter apparatus. The first lysimeter was added by compost in the amount of 11.5 ton/ha and the second one was no added compost. Observation of compost effect to vegetation was carried out to corn harvesting result consist of 1000 gram weight of corn, heavy metal content and acute toxicity test.         Results reveal that the compost of sludge waste generally contains total heavy metals are below the  quality  standard of  compost according to SNI and some other state (USA, Europe Union and Australian).  Compost had tough pH of 6.5-7.5 and had cation exchange capacity of 33.71 meq/100 g. The compost effect on dose up to 11.5 ton/ha to 1000 grains corn weight was almost the same by using manure in the same dose. The heavy metals content in the corn grain harvested from the land fertilized by sludge waste compost of 11.5 ton/ha was under the Dirjen POM No 03725/B/SK/VII/89 standard. Acute toxicity test on corn grain show that its concentration is higher than 15,884 mg/kg body weight, and it can be classified as non toxic practically.  Inti sari            Percobaan pengaruh kompos dari limbah lumpur IPAL industri kertas terhadap tanaman dan air tanah telah dilakukan. Proses pembuatan kompos dilakukan selama 45 hari dengan bahan pencampur serbuk kayu 20%v/v. Percobaan dilakukan terhadap tanaman jagung dengan beberapa variasi dosis dan sebagai pembanding adalah pupuk kandang dari kotoran ayam pada dosis yang sama. Pengaruh kompos terhadap air tanah diamati melalui percobaan dengan menggunakan 2 buah lisimeter. Lisimeter pertama ditambah kompos 11,5 ton/ha dan lisimeter kedua tanpa ditambah kompos sebagai kontrol. Pengamatan pengaruh kompos terhadap tanaman dilakukan terhadap hasil panen jagung, kandungan logam berat dan uji toksisitas akut.             Hasil percobaan menunjukkan bahwa kompos dari lumpur IPAL, umumnya mengandung logam berat total yang lebih rendah dari baku mutu kompos menurut SNI dan beberapa negara lain (USA, Uni Eropa dan Australia). Kompos mempunyai pH netral (6,5-7,5) dan nilai KTK 33,71meq/100g. Pengaruh dosis kompos lumpur IPAL sampai 11,5 ton/ha terhadap berat 1000 butir jagung relatif sama dengan yang diberi pupuk kandang pada dosis yang sama. Kandungan logam berat dalam biji jagung yang dipanen dari tanah yang dipupuk kompos lumpur IPAL 11,5 ton/ha lebih rendah dari persyaratan maksimum batasan cemaran logam berat dalam makanan untuk kelompok sayur dan hasil olahannya menurut Dirjen POM No. 03725/B/Sk/Vii/89. Hasil uji toksisitas akut jagung lebih besar dari 15884 mg/kg berat badan dan termasuk klasifikasi praktis tidak toksik.
