Urbanization, increase in population and change in lifestyle of human beings increased pressure on natural resources and accumulation of industrial waste in the environment. Dumping and landfilling of such industrial waste especially the solid waste is leading towards severe environmental degradation in the form of water pollution, air pollution and soil pollution etc. Due to increase in installation of more paper mills, there is rapid increase in quantity of solid waste from these industries. In recent years, utilization of lime mud generated from paper mill has been emerged as a potential method to reuse/recover the usable rich material and reduce the quantity of waste and its disposal cost for landfilling/dumping. In this experimental examination, an effort has been complete to examine the behavior of the bricks developed using the waste (lime mud) from paper industry waste and other paper sludge by partial replacing the clay to the extent from 10% to 50%. The bricks were developed by using varying composition. Later execution various tests, it has been detected that bricks made from partial replacement of clay with lime mud are light weight, having desirable compressive strength, corrosion resistant. The indoor air quality assessment of buildings made of these bricks indicted little to no impact on ambient air quality. [ABSTRACT FROM AUTHOR]

Time-limited exposure of electrode-free optically rewritable electronic paper is essential for applications, but performance characteristics can be modest. In this study, we investigate whether image writer mode can improve kinetics of the photosensitive layer order parameter, which is described by the rotational diffusion model. The model that we developed allows adjusting the transmittance spectra of polarizers. We have found that fairly uniform transmittance spectrum of polarizers enables to obtain competitive contrast ratio of 8:1 within 10 s of exposure. In comparison with long-time exposure, the reflectance coefficient is reduced by 24%. Computer-generated image is consistent with the experimental observations. [ABSTRACT FROM AUTHOR]

Mass Oxygen Transfer is a molecular diffusion of gas in a liquid depending upon its characteristics, concentration and cross-sectional area across which diffusion occurs and is accomplished in aerobic digestion of organics through different aeration equipment. Accordingly the comparative evaluation of mass transfer oxygen by different aeration equipment were conducted in existing aeration tanks of Agro Based Pulp and Paper Mill by studying the effect during pre and post injection of liquid oxygen through submerged and floating turbine systems coupled with fine bubble replacing existing coarse bubble diffuser. The dissolved oxygen levels in the second aeration tank (AT2) equipped with submerged turbine has further improved in the range of 2 to 2.5 comparison to lower values up to 1.5 mg/l observed in first aeration tank (AT1) with floating turbine systems. It was further studied that if fine bubble diffuser replacing existing pipe in both the aeration tanks are further coupled with liquid oxygen injection through submersible turbine system in both the aeration tanks shall increase dissolved oxygen levels up to 3-3.5 mg/l besides reduction in energy consumption up to 25% thus lowering overall treatment cost and further improve the treatment efficiencies for reduction a of BOD and COD at the final out let well below compliance level.

The rapid development of the industrial sector has increased either energy demand or generate a tremendous effect on waste piles. To combat the issue of poor sanitation due to waste accumulation and multiply the energy sources, the government promotes energy diversification, particularly dealing with waste management. This study aims to recycle plastic waste, paper waste and sawdust into solid fuel briquettes while observing their physical and combustion properties. Briquette production is carried out by combining waste of plastics and sawdust with binding agents, such as paper pulp and cassava starch. These materials were mixed with water, being compacted and conventionally dried under the sunlight. Solid briquette was then tested for calorific value, moisture content and volatile matter to ensure the effectiveness of combustion. The results show that the modified composition of plastic and paper with the ratio of 3:1 is physically sturdy with minor cracks, has a greater calorific value of 6801.62 Cal/gr, low moisture content (4.73%) and volatile matter (5.50%). The modified composition of paper: plastic: sawdust with the ratio of 1:1:1 exhibits more sturdy stuff, with a calorific value of 4565.47 Cal/ gr, low moisture content (1.85%) but high volatile matter (34.07%). Waste conversion to solid fuel briquette can be utilized as future green energy alternative in any major cities of Indonesia. A modified mixture of plastic : paper waste is more prone to transmit the heat despite having less capability to ignite, while the mixture of sawdust : paper is more prone to ignite despite having less capability to store and dismiss the heat.

The drape is a fabric's ability to deform when suspended under its weight in specified conditions of known size using a Drape Meter. The Drape Coefficient % (DC%) is calculated by taking the weight of paper cut out based on the shadow of the fabric. A fabric property is very important in relating to the behavior of drapes and these factors were determined by earlier researchers in developing a tool to measure drape. The Cusiks's Drape Meter was the first equipment that used the principle of shadow in reflecting the drape behavior and later on calculating the DC%. The principle introduced by Cusick has been used by a lot of researchers to determine DC% more accurately using computer captured images. In recent years, a lot of research has moved forward using software to calculate the DC% by incorporating the values of fabric properties to create an image for the drape. A lot of work on comparing the values of DC% using conventional and simulated/virtual methods was published. The usage of particular software can predict the DC% before the actual production of fabrics. Prediction can be made based on physical properties needed on particular fabrics to be produced and thus saving a lot of time and giving more choices in fabrics selection. [ABSTRACT FROM AUTHOR]

Five fuels were tested in a common rail direct injection (CRDI) diesel engine to see how they affected soot particle distribution and the engine's controlled and unregulated emission characteristics (M15, M25, and M35). The findings demonstrated that regulated emissions of carbon monoxide (CO), hydrocarbons (HC), and particulate matter (PM) could be efficiently controlled to a very low level when mahua oil biodiesel (MOB) in diesel was utilized in conjunction with ideal engine working situations. Paper filters were employed to remove diesel dust. Entire particulate matter main particles were < 100 nm in width, with the average diameter for the biodiesel mixes falling among 20 and 26 nm. PM particles had uncontrolled emissions including Pb, Mn, and Ba, while M100 had 56.72% fewer xylene emissions, 22.49% fewer toluene emissions, and 19.45% fewer benzene emissions compared to M0. As a result, MOB is a wonderful option for reducing pollution from diesel engines and other sources, both in the form of controlled and unregulated emissions. [ABSTRACT FROM AUTHOR]

Paper-making raw materials are a mixture of pure wood pulp and recycled pulp. Recycled pulp is obtained from used paper imported from abroad, in addition to the development of paperless culture also has an impact on the reduced availability of raw materials. Empty bunch fiber of palm oil is one of the natural materials that have the potential to be used as an alternative to a pulp for the manufacture of cardboard paper because it has a high holocellulose content. This study has successfully developed cardboard paper developed from oil palm empty fruit bunch pulp with 6 variations of treatment, steam, no steam, NaOH 2.5%, NaOH 5% and mill duration (20 minutes and 30 minutes). The developed cardboard paper is then tested for its water absorbency. Water Absorbency value testing is done by the Cobb method (60). Based on the test results obtained the water absorption values is in the range of 500 - 600 g/m2. Cartons that received treatment, no steam, added NaOH 2.5%, and milled for 30 minutes, has the lowest water absorption value compared to others. [ABSTRACT FROM AUTHOR]

The widely use of petroleum-derived mineral oils for the production of offset printing inks has resulted in several environmental impacts. The suitable approach to develop alternative resources is palm oil fatty acid methyl ester (FAME) as a substitute for petroleum-based solvent. This study aimed to investigate the surface properties of palm oil-based offset ink on gloss-coated paper surfaces in terms of printability. The "green" varnishes were prepared with palm oil FAME as solvent, rosin-modified phenolic resin, and different vegetable oils linseed oil (FAME-LO) and soybean oil (FAME-SO) have been used as drying oils. The FAME-based Cyan offset printing inks have been prepared their properties compared with standard conventional inks. Printing tests were carried out using the IGT-A2 printability tester. Contact angles of water, methanol, and hexane on the surface of printed ink were measured using Contact Angle Analyzer. The surface free energy (SFE) and its components were calculated using Girifalco-Good-Fowkes-Young, Owens-Wendt, and van Oss-Chaudhury-Good methods. The results showed that as the liquid contact angle increased, the surface energy decreased. The surface energy of FAME-SO ink printed samples 36.36 mJ/m2 was higher than the unprinted paper 35.84 mJ/m2. Since high surface energy will affect the bond strength of the ink to the substrate, this will be an advantage for multicolor prints requiring good ink adhesion, which will enlarge the acceptance of other colors to be printed on the previous color.

This paper is about paper or journal review of two-phase flow boiling pressure drop in propane (R290) refrigeration system and summarized several researches that will useful in terms of HVAC-R equipment especially in heat exchanger i.e., evaporator design. Early researcher has been conducted research with respect to the channel dimension (diameter and aspect ratio) as in Coleman (2000). Recent research of flow boiling with combined parameters such as heat transfer coefficient (HTC) and pressure drop shown that some parameters affected pressure drop inside unconventional channel (mini and microchannel) such as superficial vapor velocity, mass quality, mass flux, heat flux, saturation temperature (and pressure), and Reynolds number where flow regime of the pressure drop are mostly annular flow, intermittent flow, slug and churn flow but less or few of them found a relation of channel dimension i.e. diameter and aspect ratio towards two-phase flow pressure drop (as in Coleman (2000)). It is recommended that for further study and research, study of two-phase flow boiling pressure drop must conduct in the unconventional channel such as minichannel or microchannel i.e., capillary tube and incorporate Reynolds number of the flow (both vapor and liquid), channel dimension (diameter and aspect ratio), surface tension, and shear stress influence from two-phase flow fluid and then plot the data to the recent and or existed flow pattern map of any flow regimes especially to the refrigerants ones.

Chlorine-based bleaching agent can brighten the pulp effectively, but it harms the environment, especially water pollution. Thus, hydrogen peroxide, a total chlorine-free (TCF) bleaching agent is applied in this research to bleach pulp derived from Sesbania grandiflora. Sesbania grandiflora is being chosen as raw material due to its ideal characteristics as pulp source and native in Malaysia. This research aims to determine the effects of hydrogen peroxide on Sesbania grandiflora pulp and evaluate the paper properties made from Sesbania grandiflora pulp. The research was carried under different bleaching durations, 20 minutes, 40 minutes and 60 minutes under a constant temperature of 50°C and 3% concentration of hydrogen peroxide. The physical, optical and mechanical properties of Sesbania handsheet were measured according to the standard TAPPI. The overall result presented a significant effect on kappa number and handsheet brightness but little on mechanical properties. The longer bleaching duration gave the least kappa number of the Sesbania pulp, thus, improving the brightness of the Sesbania handsheet. However, it did not affect the strength properties of the handsheet. In this research, 60 minutes of bleaching duration on Sesbania grandiflora pulp exhibits the optimal bleaching performance without compromising paper mechanical properties significantly.

Neo vernacular is a modern architectural style inspired by traditional vernacular buildings. The concept of neo vernacular architecture is a continuance of the Klaten people's ancient identity as part of Javanese culture, particularly in Central Java. One technique to construct architectural works founded in the local culture is to look for values rooted in Javanese culture. This paper is the product of a final project whose goal is to develop a sustainable architectural identity in Klaten based on local wisdom, which will be applied to the "nadir" transit hotel. This transit hotel should be able to accomplish the goal and objective of a successful Klaten city with devoted, intelligent, autonomous, and cultural citizens. The location, 53 meters south of Klaten Station, is one type of development of supporting facilities for the commuter line scheme. This is one of the KAI activities at Klaten Station that attempts to make it easier for visitors to obtain long-term support. Folk architecture gives rise to vernacular architecture, which evolves from it. It arose from and was entrenched in the ethnic community's traditions, and skilled craftsmen built it with years of expertise. The gunungan and Klaten limasan house concept is an alternative that is integrated with contemporary design to create a transit hotel with a character that may reflect the city of Klaten's identity as an independent and cultured district.

The effect of the membrane separation process to concentrate the xylanase was tested to restrict cellulase dosage on the lignocellulosic waste. Xylanase produced from Streptomyces lividans expressing an endo-xylanase gene from Kitasatospora sp. was concentrated by nanofiltration membrane NTR-7410. This resulted in a seven-fold increase in xylanase activity without changing its specific activity. The saccharification of dilute acid-pretreated empty fruit bunch (EFB) was performed by applying membrane-concentrated xylanase compared with its un-concentrated to commercial cellulase loaded at one filter paper unit/g-biomass. Both glucose and xylose yields obtained by using concentrated xylanase (19.49% and 41.51%, respectively) were higher compared to un-concentrated xylanase (11.71% and 28.71%, respectively). Xylose-assimilating Saccharomyces cerevisiae yeast at initial of 0.5 g/L was then inoculated into the sugar solutions. The yeast had increased ethanol titer and productivity from sugars obtained by using membrane-concentrated xylanase (7.13±0.60 g/L and 0.59±0.06 g/L/h, respectively), compared by using un-concentrated xylanase (4.56±0.43 g/L and 0.38±0.02 g/L/h, respectively).

In order to accommodate the country's growing population, the number of apartment complexes has increased dramatically. Most new apartment complexes include a variety of modern amenities such as a supermarket, a medical centre, EV charging stations, vending machines, and many more. To use these amenities, we normally need to have a credit or debit card, or even cash on hand. Also, there are numerous identity and government cards that a person must carry with them at all times. Keeping track of all these cards can prove to be quite tedious and time-consuming. Furthermore, the majority of these apartments feature the standard lock and key method of unlocking the doors of the residing occupants which adds to the load of carrying about house keys along with all of the other cards. Life would be so much easier if we could replace all of these numerous bank cards with just one. Using a single card to access all services, such as EV charging or purchasing items, and even as your home door key. With the tap and go feature, the user does not have to pay at the same time but can make a payment all at once when the statement arrives at the end of the month, saving both time and keeping track of all transactions with ease. Hence, we propose in this paper a smart card that uses RFID technology to access all of the many amenities in apartment complexes. [ABSTRACT FROM AUTHOR]

Rice straw can be an alternative material for producing great pulp and paper also can be produced by several variations of the pulping process. This study was conducted to prepare and evaluate the hydrophobic rice straw pulp soda using atmospheric hot soda (AHSP) and soda (SP) pulping methods and modified with water-soluble chitosan treatment. The pulps were modified with water-soluble chitosan treatment at 1% and 2%. The screen pulp yield, kappa number, and delignification selectivity were analyzed to evaluate the properties of the pulp, while hydrophobicity properties were evaluated by its water absorption capacity and wettability. The FTIR was used to investigate the possibility of a new functional group formation after modification. The screen pulp yield of AHSP (29.22%) was relatively higher than SP (21.94%). However, SP pulp has a lower kappa number with higher delignification selectivity than AHSP pulp. After pulp modification, the hydrophobicity of the modified pulp increases in line with the increasing concentration of water-soluble chitosan. The AHSP pulp with a 2% water-chitosan treatment has the highest hydrophobicity indicated by the lowest water absorption capacity at 60 minutes i.e 41.99%. Therefore, based on hydrophobicity analysis, AHSP and SP modified with a 2% water-soluble chitosan treatment have better hydrophobicity. [ABSTRACT FROM AUTHOR]

Polar code is a class of linear error-correcting codes that may demonstrably achieve the capacity of discrete memoryless channels. In the last decade, they have piqued the interest of industry and academia, such as the 5G (5th generation) wireless communication system standardization process. Although polar codes are proven to achieve the Shannon limit, their performance degrades at finite-code lengths, particularly in low signal-to-noise ratio (SNR) environments. So in a regime with finite _length, the performance of polar code may be improved by several techniques, such as Turbo Polar Codes (TPCs). Various Soft_in_Soft_out (SISO) decoder techniques, such as soft_cancellation (SCAN), belief_propagation (BP), and soft_successive_cancellation_list (SSCL) can be utilized in TPC. On the other hand, using a simple scaling factor scheme to minimize the overestimation of extrinsic information and its correlation with intrinsic information can further improve performance. Different termination techniques are proposed in the literature to reduce the required number of iterations, especially at high SNR. Error detection and correction systems are utilised to reduce energy consumption. This paper reviews some of the recent decoding techniques used in TPC. [ABSTRACT FROM AUTHOR]

This study aims to identify the performances of cationic starch (CS) and sodium carboxymethyl celluloses (CMC-Na) as dry strength additives (DSA). The CS and CMC-Na were incorporated with to pulp slurry in different dosages (0.5%-2.0%) during stock preparation. The basic weight of 80 g/m2 was made for each treatment. The results showed that the utilization of CMC-Na had better mechanical properties compared to the CS for all treatments. In general, apparent density and mechanical properties were significantly affected by the addition of DSA. However, through the observation of the experiment, the enhancing effect of CMC-Na on mechanical properties of wastepaper was much higher than using CS except for tear strength. The FESEM imaging results can also help prove the best DSA used in wastepaper production. [ABSTRACT FROM AUTHOR]

Waste is produced in large quantities all around the world, causing serious environmental problems. Construction and demolition (C&D) trash accounts for a significant fraction of global solid waste production, with the majority of it ending up in landfills. Concrete engineers have truly recommended the possibility of precisely treating and reusing such waste as aggregates in fresh concrete, particularly for lower-level applications, according to their research. Papercrete is a sustainable building material since it uses less cement and makes extensive use of recycled paper. It provides a number of benefits in the manufacturing industry, including a reduced carbon footprint and recovered fabric. Poor embodied strength, low utilization, and so on. The concrete rubble collected from C&D waste is used as a fine aggregate in the manufacture of papercrete bricks in this study. As a result, both waste paper and C&D debris were used, reducing landfill disposal and promoting low-cost, light-weight, and environmentally friendly construction materials. [ABSTRACT FROM AUTHOR]

The catalytic electroreduction of carbon dioxide represents a promising technology for the management of the energy sources and the abatement of CO2 emissions. For the industrial implementation of this process, it is required the development of a selective and stable nanostructured catalytic electrode. In this study, we evaluated the synthesis of nanostructured metallic electrodes produced by galvanostatic electrodeposition of copper onto a carbon paper support. The effects of deposition current density on morphology and catalytic properties of the electrodes were analyzed. The formation of copper nano and microstructure was observed on the external structure of the carbon paper support. Regarding the morphology, a correlation between applied current density and deposition structure was found. Electrodeposited electrodes showed a catalytic selectivity towards the production of carbon monoxide almost four times greater than copper foil electrodes. An inverse correlation between deposition current density and catalytic selectivity was observed. A decrease in the deposition current from -6 mA cm-2 to -2 mA cm−2 resulted in a doubling of the measured selectivity. [ABSTRACT FROM AUTHOR]

A manufacturing system is a collection of equipment and human resources integrated to carry out the operation process into a quality finished product. With various activities in it making the production process one of the spearheads of creating a product in accordance with market needs, it is necessary to have a systematic, effective and efficient workflow to optimize the workstation at production time. PT XYZ manufactures carton boxes of various sizes. Cardboard paper as raw material is obtained from several other paper mill companies. PT XYZ has an imbalance of production efficiency which is a bottleneck (stacking) at the manual stitching workstation that is the carton box's union with the stapler. Based on the existing problems, this study aims to determine the process of producing carton boxes and identify workstations that experience bottlenecks. The estimate production demand and be careful to minimize congestion to optimize work efficiency at workstations in the production process and compare repair costs conducted. The data obtained will be predicted using quadratic forecasting to determine the shadow of future requests. The method used to minimize congestion and handle work efficiency at each workstation is Theory of Constraint (TOC). With the Theory of constraint method, the percentage of loads experiencing congestion is 105.89%. After the best choice is made by adding 1 operator to the connection process, the percentage of loads experiencing congestion is 70.59%. So, the bottleneck condition is solved, and production runs smoothly. [ABSTRACT FROM AUTHOR]

Synthesis of heteronuclear complexes of Fe(III)-Mn(II)-Tartrate is reported here. The tartrate based heteronuclear complex was developed as functional material for catalytic applications and molecular magnets. Effect of type of Fe(III) salts and reaction temperature in the solvothermal synthesis of the targeted complex is also investigated. FeCl3 and (NH4)Fe(SO4)2 were used as the source of Fe(III) salts, in which the Fe(III) salt solutions were then mixed with solutions of MnCl2 and L−tartaric acid in a Fe(III)-Mn(II)-Tartrate mol ratio of 2:2:5 in a 50 mL of Teflon-autoclave. A mixture of dimethyl formamide and distilled water (1:3) was used as the solvent. The solvothermal reaction was done at 110 and 130 °C, respectively, for 2 hours. Solids that precipitated out from the reaction were separated by filter paper, dried in an oven, and then characterized by Fourier Transform Infrared (FTIR) spectroscopy, atomic absorption spectrophotometer (AAS), and powder XRD analysis. Experimental data shows that all four reactions resulted in identical pale yellow-greenish fine powder in different yields. FTIR analysis confirms the presence of tartrate ligand based on specific absorptions, namely a broad band around 3400 (O–H) cm−1, a sharp peak around 1650 (O–C=O) cm−1, and twin sharp peaks around 1400-1100 (C–OH) cm−1. Moreover, AAS confirms the presence of both Fe and Mn in all samples in a considerably significant amount. Powder XRD analyses confirmed that the synthesized complexes have identical crystal system. These results indicate that complexes of Fe(III)-Mn(II)-Tartrate were formed and the synthesis of the complex were not influenced by the type of Fe(III) salts or by the reaction temperature.

Residuals from pulping process of Iraqi pulp and papermaking factories was taken to produce a thermal insulator by wetting, crushing, and pressing to a certain shape to get a board called by the authors as "Cellulose Board" that can be used as a thermal insulator for air conditioning and piping systems carrying hot water for heating. It was found that thermal conductivity of cellulose board is 0.0311 W/m.c hence it can be compared with common thermal insulators such as rock wool and fiber glass which is expensive from economic point of view. It is recommended to use vapor barriers to prevent board from getting moisture. Additionally, it is recommended not to use Cellulose Board in a high temperature application. [ABSTRACT FROM AUTHOR]

Species producing raw material for pulp and paper that can be grown in the high altitude lands are still limited. One of the potential species for this area is Eucalyptus urophylla. Tree breeding strategy by a progeny test is performed to increase its productivity. The initial selection is implemented at the nursery level by assess the variation of family (mother trees' progeny) (F1). The research aimed to determine the F1 variation by the growth performance of 6 months old F1 seedlings. Samples consisted of progeny from 27 family originated from provenances of East Nusa Tenggara, Indonesia. Indicators of growth performance and determination of rankings are assessed from the seedling's diameter, height, and robustness. The results showed that E. urophylla had high growth performance variation. Based on their growth performance, the best seedlings were from the family of A25, A27, A23, A19, A20 and A21. Genetic diversity among F1 categorized moderate, based on heritability of height (H2=0.37), diameter (H2=0.45) and robustness (H2=0.6). Coefficient of genetic variance (CGV) and coefficient of phenotypic variance (CPV) are more than 20%, and 27 mother trees are divided into 4 clusters. The existence of genetic diversity at the seedling level becomes the material for further testing in the field. [ABSTRACT FROM AUTHOR]

the issue of rising electricity demand in the building sector is one of the major challenges. Therefore, the Building Management System (BMS) inside the building. Since the PV, national grid, and diesel generators supplies building electrical power, so the Energy Management System (EMS) technologies are necessary to study the priority of PV to supply building power to save energy. This paper proposes a Smart Building Management System (SBMS) used with Heating, Ventilation, and Air Conditioning (HVAC) in addition lighting systems. HVAC is controlled with occupancy sensors, temperature control, and load control. Lighting systems are controlled through occupancy sensors and daylight sensors to make them operate to minimize electricity consumption. Using Artificial Neural Network (ANN) control of the EMS in this work, SBMS and EMS are created and simulated using two case studies to supply public buildings. The first situation is SBMS without EMS and the second situation is SBMS with EMS. Finally, the results showed the impact of SBMS on the reduction of energy consumption for HVAC systems and lighting (20% on summer day and 11% on winter day), as the energy consumption was reduced for both HVAC and lighting by about (54% on a summer day and 44% on a winter day) because we added the scenario of case two to the one scenario case in a public building.
