Full textAbstract:
Research was performed into the use of hemp shive as a fast-growing and carbon-storing agricultural waste material in the production of particleboard for the construction industry. Hemp shives were acquired and prepared for board production with the use of milling and sieving to reach two target groups with 0.5 mm to 2 mm and 2 mm to 5.6 mm particle size ranges. The cold pressing method was used to produce hemp boards with Kleiberit urea formaldehyde resin as a binder. The boards were made as 19 mm thick single-layer parts with a density range of 300 ± 30 kg/m3, which qualifies them as low-density boards. Exploratory samples were made using milled hemp fibers with higher density. Additional components such as color pigments and wood finishes were added to test improved features over raw board samples. Tests were performed to determine moisture contents, density range, structural properties, and water absorption amounts. Produced board bending strength reached 2.4 MPa for the coarser particle group and thermal conductivity of 0.057 ± 0.002 W/(mK). The results were compared with existing materials used in the industry or in the development stage to indicate options of developed board applications as indoor insulation material in the construction industry.

The need of wood as one of raw materials in furniture industry keeps increasing. One of efforts to reduce wood consumption is to develop research by creating composite design from material that contains sellulose to be particle board. Particle board is one of material alternatives that can be wood substitute. The objective of this research is to investigate the effect of natural-adhesive-mixture composition (acacia bark and gambier) with oil-palm-empty bunch toward mechanical property of particle board. Characterization of particle board was carried out by undertaking mechanical property testing (tensile strength and compressive strength) under wet and dry conditions. Composition variations of adhesive and oil-palm-empty bunch were 30:70; 40:60; 50:50; 60:40; 70:30. Making process of particle board is carried out by mixing oil-palm-empty bunch and adhesive with addition of 2% para-formaldehyde and water as much of 10%. Furthermore, the mixture is compressed by using Hot Press at temperature of 150oC and pressure of 10 kg/cm2 for 15 minutes. The research result indicates that the higher the adhesive composition (either adhesives of acacia bark or gambier), particle board resulted is better. In dry condition, values of the tensile strength of particle boards that have acacia bark adhesive and gambier adhesive have range of 84.2 - 104 Kgf/cm2 and 83.4 - 81.5 kg/cm2, respectively. Whereas, values of compressive strength of particle boards that have adhesives of acacia bark and gambier are in the range of 6.8 - 10.5 kg/cm2 and 6.3 - 9.3 kg/cm2, respectively. The values of tensile strength and compressive strength are obtained on compositions of adhesive: oil-palm-empty bunch ≥ 40:60, and they have fulfilled satandard of SNI 03-2105-1996. The values of tensile strength and compressive strength of particle board in wet condition, either adhesives of acacia bark or gambier, have not fulfilled standard of SNI 03-2105-1996.Keywords: empty-bunch-oil palm, acacia bark, gambier, particle board, tensile strength

Wood waste materials such as flakes, particles, sawdust, planer shaving, which are residues from furniture industry can be utilized to manufacture many composites such as particleboard. The most commonly used particleboard has three layers: two face layers and one core layer. The face layers consist of fine particles and the core layer is made of coarse particles.This study aimed to show the effect of shelling ratio and particle characteristic on physical properties of three-layer particleboard with high density core and different particles on surface layers. The materials used in this study were hinoki (Chamaecyparis obtusa) strand and knife-milled Douglas-fir (Pseudotsuga manziesii) as surface layers and hammer-milled matoa (Pometia sp.) as core layer. The wood particles were collected from a wood company. Adhesive used was MDI resin (methylene diphenyl diisocyanate) with 6 % content in mat preparation. The pressing conditions were: temperature 180°C, pressure 3 MPa and pressing time 5 min. The target density was 0.72 g/cm3 with board size of 340 mm x 320 mm x 10 mm. Factors used in this study were layer structure according to board shelling ratio and particle characteristic. The parameters of this study were density, moisture content, thickness swelling, water absorption, linear expansion and vertical density profile.The results of this study indicate that all boards meet the requirements of JIS A 5908-2003. Higher shelling ratio of surface layers resulted in higher physical performance of three-layer particleboard. In terms of particle type, hinoki strands showed the best performance in board density and linear expansion, while Douglas-fir particle showed the best performance in moisture content, thickness swelling and water absorption. Improvement of physical properties of particleboard with high density wood particles in core layer can be conducted by adding surface layer with higher quality wood particles such as hinoki strands or Douglas-fir particles. Compared to Douglas-fir particles, hinoki strands as surface layers contribute to higher enhancement of three-layer particleboard with matoa as the core layer.

Full textAbstract:
Currently, the use of board materials as a material intended for the dry construction of building structure cladding in the building industry has become widespread. The most common types of board materials include wood-based boards (particle, fibre, laminated / plywood, oriented strand boards [OSB]), cement-bonded particleboards and gypsum plasterboards or gypsum fibre boards. In the case of board materials based on inorganic binders, these are most often represented by boards in which the fillers used are bonded by plaster or cement. Wood can then be used as filler, which is predominantly an assortment of inferior-quality trees or comes from a short rotation coppice, treated by various technological processes. Microstructure and material composition have the greatest influence on the physical and mechanical properties of the boards. The use of the boards in the internal or external environment is determined by their individual properties. Another indicator for the possible use of boards is the form of moisture with which the board comes into contact after installation into the structure. For the external environment, the boards have to withstand mainly liquid moisture; in contrast, in an internal environment, the boards come into contact mainly with air humidity. The diffusion properties of the individual products are also crucial for the overall design and use of the boards for structure cladding.

There is an increased awareness to preserve the environment in the present day society. Rice Husk (RH),is the widely available agricultural wastes and is a serious concern for the environment. It is a potential material for use as alternative material in the construction and insulation industry. The particle board made from rice husk (RH) or rice husk ash (RHA), bonded by resin under the application of pressure and temperature. Urea formaldehyde is the organic resin used in general for interior use whereas phenol formaldehyde for external disclosure. The said resins are preferred for their water-resistant properties and better binding strength. The present study investigates the potential of rice husk reinforced boards by experimenting the different compositions and thicknesses. The objective is to perform a thermal analysis of the processed Rice husk boards. Boards made from rice husk are biodegradable unlike glass wool & other synthetic insulations. After experimenting on different fabrication conditions, six samples were finalized and were tested for physical and thermal viability in their applications. This study found that by adding ash of rice husk, the density of board decreases with respect to the board of same weight and consisting of rice husk only. Moisture Content is higher in case of boards with RHA but is within permissible limits. RHA reinforced boards have improved thermal properties, which is desirable in case of insulation boards.

Excessive use of wood can cause the amount of wood to be cut to increase as a result, wood is increasingly difficult to obtain. It should be realized that the use of forest products through the processing industry must begin to be observed and efforts must be made to use raw materials that must be able to be processed and produce useful and valuable products, even optimizing materials and minimizing waste or being environmentally friendly. The wood and non-timber waste is used for recycled products that can provide economic value benefits for the community. The raw material for particleboard comes from the rest of the wood processing in the sawmill industry, so it doesn't require high raw material requirements. The activity of utilizing processed wood powder waste is carried out at UKM Aisyah Furniture, Palangkaraya. The process of making particle board made from sawdust can use fox glue. The distribution of particles and adhesive that spreads evenly tends to get a more even board density. Knowledge of the utilization of wood-processed powder waste can be used to utilize wood-processed sawdust waste so that it has economic value

Alternative resources as substitute for wood raw materials has increased in the particleboard industry because of the depletion of forest resources. Studies of particleboard using wood residues and agricultural by-products have examined wheat straw, rice straws, husks, bagasse, walnut/almond shells, and palm trunks. Rice husk is the by-product in rice milling operation with an approximately 20 percent of the total weight of the paddy grain being processed. Despite the abundant nature of this waste product and its unique physical and chemical properties, it is not being fully harnessed in Nigeria. Only a little portion of the rice husk produced is utilized in a meaningful way, the remainder is burnt into ashes or dumped as a solid waste with little being used in animal feed formulation.
Particle board was produced from rice husk, an agro-waste and cement as binder. Physical and mechanical properties of the board were determined. The results show that, the percentage of thickness swelling and water absorption increased with increase in proportion of the binder to the rice husk. The Modulus of elasticity (MOE) values increase with increased mixing ratio for both the board thickness, while MOR values decrease with increase in mixing ratio for both particle sizes. Since the construction industry is a growing one, the use of renewable resources such as rice husk can reduce the strain on forest resource and form an excellent replacement for wood and wood based composite materials.

The development of particleboard manufactured using non wood biomass has become important due to the decreased of wood as main raw material for the particleboard industry. Corn husk (Zea mays L.) and Sembilang bamboo (Dendrocalamus giganteus Munro) are lignocellulosic biomass that has potential as renewable materials for hybrid particleboard. The purposes of this study were to determine the suitability, the effect of adhesive type, and particle composition on physical and mechanical properties of hybrid particleboard made of corn husk and Sembilang bamboo particles. The adhesive types used were urea formaldehyde (UF) and phenol formaldehyde (PF) with 10 wt% adhesive content and the composition of corn husk : Sembilang bamboo was set at 100 : 0, 75 : 25, 50 : 50, 25 : 75, 0 : 100 (% w/w). The target density of hybrid particleboard was set at 0.80 g/cm3. The boards were manufactured at 130 °C for UF and 150 °C for PF press temperature, 10 minutes and 2.5 MPa for the pressure of the hot press. The results showed that hybrid particleboard properties improved with increasing the amount of Sembilang bamboo particles in the board. Hybrid particleboard properties affected in ascending order were modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB) and screw holding power (SHP). Generally, hybrid particleboard bonded PF adhesive has better properties than bonded UF adhesive. Results indicated that the addition of Sembilang bamboo particles in the mixture resulted in better properties of hybrid particleboard.

One of the important auxiliary processes in the wood processing industry, especially making particle board or fiberboard is gluing. Bonding process is influenced by the type of adhesive material, process and place of gluing, apart from the nature of the taped material. Until now, the adhesive material commonly used include synthetic adhesive Urea Formaldehyde (UF), Phenol Formaldehyde (PF) or Melamine Formaldehyde (MF).The rotary mixer is designed in a simple to mixing between partiket with glue that adhesion earns homogen. Rotary mixer has 5 (five) major units, namely: the framework tools (foundation), tubes mixing, mixer circuit, drive circuit and compressor. The working principle of this tool is stirring directly between the wood particles with adhesive. Material in the form of wood particles (after a specified weight) is inserted first into the mixing tube. Once the machine is turned on, a series of rotating stirrer will stir load (material particles). The next process is to insert adhesive into the tube, either by spraying or directly poured slowly little by little. Key wood : particles, adhesive, rotary mixer.

The effect of waste tar from particle board factories was investigated relative to some physical and biological resistance properties of Scots pine (Pinus sylvestris) and beech (Fagus orientalis) woods. Solutions were prepared by dissolving waste tar in ethanol:toluene (1v:1v) in concentrations of 5%, 10%, 15%, and 20%. These solutions were forced deep into the Scots pine and beech woods under vacuum and pressure (deep treatment, DT). In addition, surface coating (SC) was applied by spreading 96% waste tar on the wood surfaces after treatment. Deep-treated and surface-coated (DT+SC) wood samples were exposed to the wood-decay fungi Trametes versicolor L. and Neolentinus lepideus Fr. for 12 weeks. At the same time, sample blocks were tested against wood-destroying house borer (Hylotrupes bajulus) larvae for 16 weeks. Total phenolic content, water uptake, water-repellent efficiency, and surface contact angle were tested. Although a mean mass loss resulting from T. versicolor of 31.1% was seen in the Scots pine control samples, only 3.87% mass loss was found with a concentration of 20% (DT + SC). The H. bajulus larvae mortality rate was 80% in the Scots pine wood samples deep-treated with 20% waste tar.

Abstract Today there is a great demand in the market of wood-based panels like medium density fibreboard (MDF), plywood and oriented strand board (OSB). These boards provide functionality in various industrial fields from building to furniture production. All are produced from timber and some type of binding resin, the most often used in Europe are phenol formaldehyde (FF), isocyanate (MDI) and melamine urea formaldehyde (MUF). These resins guarantee sturdiness of the material but are toxic to humans and makes recycling of the wood-based panels very difficult. There are attempts of wood-based panels industry to transition away from fossil-based adhesives. Various resins have been developed using lignin and tannin or protein. Soy based adhesive SOYAD™ has already reached the market, other soy protein-based adhesives are integrated into ultra-low formaldehyde emission particle boards like Nu green 2® and Transform™. This paper gives an overview on bio-based adhesives that are used or have the potential to be used for wood-based panel production.

To increase the sustainability of prefabricated timber buildings and constructions, composite timber beams with “box” cross-sections were developed in collaboration with an industry partner. They were constructed from a solid timber frame and from webs made of residual waste wood-particle boards from prefabricated timber buildings production. The developed beams’ design concepts presented in this paper were governed by architectural features of prefabricated timber buildings, geometrical limitations, available production technology, and structural demand related to various possible applications. The paper presents the results of experimental bending tests of six variations of the developed composite timber beams constructed by mechanical fasteners only. The developed design concept of composite timber beams without adhesives is beneficial compared to glued beams in terms of design for deconstruction and lower VOC emissions. The tests were conducted to study the influence of the following parameters on the beams’ mechanical behavior: (i) web material (oriented strand boards (OSBs) vs. cement-particle boards); (ii) the influence of beam timber frame design (flanges and web stiffeners vs. flanges, web stiffeners, and compressive diagonals), and (iii) the influence of stiffener–flange joint design. Besides the beams’ load-bearing capacities, their linear and non-linear stiffness characteristics were the main research interest. While adding compressive timber diagonals did not prove to significantly increase the stiffness of the beams in the case of cement-particle board webs, it increased their load-bearing capacity by enabling the failure of flanges instead of prior webs and stiffener–flange joints failure. For beams with OSB webs, failure of the bottom flange was achieved already with the “basic” timber frame design, but timber diagonals proved beneficial to increase the stiffness characteristics. Finally, mechanical characteristics of the developed beams needed in structural design for their application are provided together with further development guidelines.

The raw materials used to manufacture thermal insulation in buildings consume a large amount of energy and are not generally biodegradable, which means it is necessary to increase the use of renewable, eco-friendly resources such as plant fibers in order to reduce the environmental problems this generates. The wood adhesives developed by the petrochemical industry offer excellent performance and are affordable. However, their use has an expiry date and in the future they will be rejected due to the environmental and health problems they can cause. The objective of this work was to develop a new eco-friendly biocomposite that could be used for thermal insulation in buildings. Boards were manufactured from giant reed particles with a particle size of 2 to 4 mm, using 5 and 10% by weight of citric acid as a natural binder. Experiments were then carried out to investigate the effect of board density on mechanical, physical, and thermal properties. A new type of composite was obtained with a thermal conductivity of 0.081–0.093 W/m K, which makes it suitable as an insulating material. The boards with a density of 850 kg/m3 had a modulus of rupture (MOR) of 12.5 N/mm2, a modulus of elasticity (MOE) of 2440 N/mm2, and an internal bonding strength (IB) of 0.61 N/mm2, and they could be used as insulation panels for divisions and enclosures in buildings.

Full textAbstract:
WC-Co (tungsten carbide-cobalt) composites are widely used in industry, wear-resistant parts, and cutting tools. As successful tool materials, WC-Co carbides are widely applied in metal cutting, wear applications, chipless forming, stoneworking, wood, and plastic working. These materials are exposed to severe solid particle erosion by sand particles, such as in the wood industry. During the production of furniture with HDF (High Density Fibreboard), MDF (Medium Density Fibreboard), or OSB (Oriented Strand Board), there are observed problems with tool erosion. Contamination, mainly of the HDF by sand, is quite often, which is why all tools used for the machining of such materials are exposed to erosion by sand particles. Although many studies have been performed on the erosion of various metals, and erosion models exist to predict their erosion behavior, the issue is still relevant. The aim of the study was to determine the effect of grain size (submicron, ultrafine) and the manufacturing technology (SPS—Spark Plasma Sintering, conventional) used on the erosive properties of WC-Co sintered carbides. Sinters produced by the SPS method with different sizes of WC grains and commercial samples were used for the tests. Ten two-hour cycles were carried out under medium conditions of quartz sand and quartz sand with 10% SiC added. Used samples were characterised using scanning electron microscopy (SEM) and roughness was determined. Furthermore, erosion studies allowed individuating a wear mechanism as well as the possibility to foresee cutting performance in prospective application.

Full textAbstract:
Purpose – The purpose of this paper is to prepare high-performance agro-based composites from the non-toxic rice bran-urea-formaldehyde (RB-UF) adhesive system. Investigations have continued for production high performance agro-based composites using environmentally acceptable approaches. The utilisation of such system with the available used local agro-based wood products (sugar-cane bagasse, SCB) adds economic value and helps reducing the environmental impact of commercial urea-formaldehyde (UF) adhesive, and most importantly, provides a potentially inexpensive alternative to the existing commercial artificial wood-panel mills. Design/methodology/approach – Optimising the process for incorporating the RB in UF, as wood adhesive for binding the bagasse fibres, was carried out, by partially replacing commercial UF by denaturalised RB in slurry (wet) and dry form or through synthesis of UF. The denaturalisation of RB was carried out at different pHs (10-11) and at temperature 60°C for two hours. While incorporating the RB during synthesis of UF, it was carried out according to the method reported elsewhere. The formulation of adhesive components, pH value of the denaturalisation stage and the process of incorporating the RB were optimised. Assessment of the role of RB adhesive was specified from its free-formaldehyde (HCHO) content, as well as the properties (mechanical and physical properties) of the produced composites of bagasse particle board type, in comparison with the environmental impact of commercial thermosetting resin (UF). Findings – The promising adhesive system exhibits improvement in the environmental performance (as E1 type) over a commercially UF adhesive (as E2 type), besides providing boards fulfill the requirements of grade H-3 (according to ANSI A208.1 (NPA1993). This adhesive system was resulted from replacing 30 per cent of UF by denalturalised RB (at pH 10) in slurry form. Where, its reduction in free-HCHO reached 53 per cent, as well as modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB) and TS of the produced boards were approximately 24.2 N/mm2, approximately 3753 N/mm2, approximately 0.84 N/mm2 and approximately 11.4 per cent, respectively. Research limitations/implications – The eco-adhesive with relatively high percentage of low-cost commercial UF (70 per cent) and 30 per cent RB, as oil production by-product, in slurry form provides good board strength and is environmentally friendly compared to SCB-based composite properties, with that produced from commercial UF. The mechanical (MOR, MOE and IB) and water-resistance properties of the produced composite comply with the standard values. Practical implications – The approach provided low HCHO-free UF adhesive with good comparative board strength and water resistance and reasonable working life. Replacing 30 per cent of UF by RB in slurry form and denaturalised at pH 10 is considered a promising inexpensive alternate adhesive (as E1) in the wood industry based on SCB wastes. Social implications – Incorporating the RB by-product of oil production to commercial UF will be beneficial for saving the health of wood co-workers and motivating the wood mill to export its wood products. Originality/value – It provided a potentially simple way to improve both the utilisation of commercial UF and SCB as industrial substrates for particle-board production. This will benefit farmers, local wood mills in Upper Egypt, significantly. Meanwhile, incorporating low percentage of RB, as oil-mill by-products, is promising to partly replace UF resin in the wood industry, minimising formaldehyde emission or toxic gasses during board formation.

Flexography is an evolving printing technology that is suitable for printing on coated and uncoated paperboard and board, nonporous substrates including metalized and paperboard foils, and plastic films used especially in the packaging industry. This study evaluated the effect of paperboard and ink characteristics on flexographic print density in paperboard. Three commercial paperboards from different companies were prepared: brown kraft from Thailand, white kraft from Spain, and test liner from Iran. Four samples of process print inks from Iran were used in this investigation. Paperboard properties, such as roughness and water absorption, and ink characteristics, including solids content, PH and particle diameter, were measured. The inks were printed on paperboards using a roll no.15 applicator with a blade metering device, and the print densities were measured. Results showed that solids content, pH, and particle diameter of printing inks influenced print density, while the roughness and water absorption of the three types of paperboard had no significant influence on print density. Results also illustrated that two levels of ink viscosity (25–30 and 50–55 mPa·s) were insignificant to print density.

Sales forecasting is very beneficial to most businesses. A successful business needs accurate sales forecasting to understand the market and sales trends. This paper presents a novel sales forecasting model by integrating support vector regression (SVR) and bat algorithm (BA). Since the accuracy of SVR forecasting mainly depends on SVR parameters, we use BA for tuning these parameters because Bat is a newly introduced algorithm and has many parameters. In order to find the best set of BA parameters Taguchi method was utilized. We validated our model on four known UCI datasets. Then we applied our model in printed circuit board (PCB) sales forecasting case study. We compared the accuracy of the proposed model with Genetic algorithm (GA)–SVR, particle swarm optimization (PSO)–SVR, and classic-SVR. The experimental results show that the proposed model outperforms the others. To ensure the robustness of our proposed model, sensitivity analysis was also done using our model to find out the effects of dependent variables values on sales time series.

Indonesia trades ten groups of wood in the Asia-Pacific region. Many forest industry problems occur during trade. Competition and interdependence in trade are research objectives. The research secondary data source is taken from UN Comtrade 2011-2021 and analyzed using the Export Similarity Index (ESI), Revealed Comparative Advantage (RCA), Trade Complementarity Index (TCI), and Intra-Industry Trade (IIT) methods. The research results show that the wood export trade between Indonesia and competing countries competes weakly with each other in the six partner countries. Indonesia is competitive in the products SITC 245 (fuel wood (excluding wood waste) and wood charcoal), SITC 248 (wood, simply worked, and railway sleepers of wood), SITC 251 (pulp and waste paper), SITC 634 (veneers, plywood, particle board, and other wood, worked, n.e.s.), SITC 635 (wood manufactures, n.e.s.), and SITC 641 (paper and paperboard). On the other hand, Indonesia and partner countries almost complement each other as trading partners in terms of exports and imports of wood. However, the integration of Indonesian wood trade with partner countries is considered weak. Products SITC 248 (wood, simply worked, and railway sleepers of wood), SITC 251 (pulp and waste paper), SITC 641 (paper and paperboard), and SITC 642 (paper and paperboard, cut to size or shape, and articles of paper or paperboard) are several product industries that have led to intra-industry trade. Policy recommendations are to utilize resources optimally, develop the wood processing industry to produce finished wood products, and improve the quality and standards of wood products in accordance with policies in trade cooperation.

The research on international trade competitiveness is progressing continuously. Environmental factors have been gradually considered in the competitiveness of international trade. However, the green assessment system of international trade competitiveness is not perfect. Building a model based on the trade economy is complex. This study combines environmental pollution data based on the forest processing industry with trade flows. Environmental trade competitiveness, pollution treatment, and trade scale were selected as the three criterion levels to construct an assessment system. The weight and score of each index were calculated by the overall entropy method. The overall entropy method is more comprehensive than the traditional entropy weight method due to introduce longitudinal comparisons of time and category. This method is a dynamic evaluation model with analysis of three-dimensional sequential data tables. The use of this method enables the assessment model to analyze more comprehensively the green level of a country’s trade in wooden forest products in terms of time and product category. The green level of chemical wood pulp and sawn timber trade in China is at a high level. The pollution treatment and trade scale of chemical wood pulp and sawn timber attained a medium level of matching. The trades in particle board, hardboard, newsprint, carton board, and wrapping paper are at medium levels of green. The trades in medium density fiberboard and plywood have poor levels of green and need to improve their green production capacity. It is suggested that China should increase investment in scientific research, as well as establish policies to restrict and treat pollution in the industry of wooden forest products, while increasing the export volumes of products with high added value. China should attach importance to the pollution resulting from the manufacture of wooden forest products. The state should support policies for these producers reducing production emissions.

The proliferation of sustainability reporting (SR) is in response to environmental and social responsibility, but investors are increasingly concerned over the effects of sustainability reporting in corporate sustainability. The Sustainability Accounting Standard Board (SASB)’s sustainability standards are acknowledged as the main framework for implementing this activity, yet the influencing factors among sustainability reports highly correlate and are diverse and complicated, especially in the semiconductor industry, which is the key driving force for economic development in China. To exploit and evaluate those key factors, this research introduces a hybrid model that integrates fuzzy rough set theory with particle swarm optimization (FRST-PSO) and a fuzzy decision-making trial and evaluation laboratory (fuzzy DEMATEL). FRST-PSO is adopted to filter out redundant and irrelevant factors, and the selected results are then inserted into fuzzy DEMATEL to depict the opaque relationships and set up a prioritization strategy for improvement among the factors. According to the findings on the magnitude of the impact, the priorities for improvement are environment, human capital, social capital, leadership and governance, and business model and innovation. Based on the results, an optimal and practical solution is proposed as the basis for information disclosure of sustainability reporting for the semiconductor industry.

Wood waste is often found in several home furniture business locations in Langsa City, including in the furniture industry in Karang Anyar Village. The problem so far is that wood waste is not processed and utilized due to a lack of knowledge in processing wood waste into a product that has economic value and wood waste will also have a negative impact on the environment. The aim of this Community Service activity is to educate and provide training to furniture business groups to utilize sawdust waste into economically valuable products such as chipboard and blockboard. The activity method begins by coordinating with partners from the Karang Anyar Village furniture industry group totaling 12 people and then preparing the materials and tools used. The stages of making chipboard and blockboard with dimensions of 40x40x10 from wood waste are then the stage of training and education for the community and monitoring the results of activities. From the results of the activity, training participants received good benefits in understanding waste and the impacts that will arise from waste with a percentage of 45% and 70% with very good grades. However, for waste processing, the training participants only got a very good understanding of 30%. The skill of making particle board from wood waste increased after training by a percentage of 55% and participants benefited from the training by 70% for an excellent score.

Full textAbstract:
The trend to replace internal combustion engines with electric zero-emission drives, visible in the automotive industry, also exists in the shipbuilding industry. In contrary to land vehicles, the requirements for the electric propulsion system of tugs are much greater, which combined with the limited space and energy on board, makes any amount of energy valuable. Strategic changes in the policy of many countries, such as the “Fit for 55” package, introduce plans to significantly reduce CO2 emissions, which favors the development of alternative drives and their introduction to new areas of operation. This article presents that it is possible to reduce the amount of energy an electric tug spends for movement by applying the Particle Swarm Optimization method to modify the shape of its hull. A statistical analysis of public data was performed to determine the speed profiles of actual port tugs. The Van Oortmerssen method was used to determine the hull resistances of the proposed tug and the impact of the hull shape modification sets on reducing these resistances. Based on the six obtained speed profiles, it was determined that one of the tested variants of modifications made it possible to reduce energy consumption on average by 2.12%, to even 3.87% for one of the profiles, and that some modifications increase energy consumption by even 6.59%.

A large number of seed spices (Cumin, Fennel, Coriander, Fenugreek etc.) cleaning-grading units are situated in Gujarat and Rajasthan. In-plant study was performed in such a cleaning-grading industry located at Unjha (Gujarat) in collaboration with Centre for Research on Seed Spice (SDAU), Jagudan, Mehsana. Apprehension for wellbeing of workers of such dust/ suspended particulate matter (SPM) generating industries are growing with time. SPM samples were collected using standard High Volume Sampler and these samples were analyzed for their respirable suspended particulate matter (RSPM) and total SPM concentration (µg/m3). The highest concentration of RSPM (< 10 micron) inside the plant was found to be 20 x103 µg/m3, while the highest SPM concentration level was 168x103 µg/m3. The average particle size of SPM was 1.96 µ to 9.43 µ while that of RSPM was 1.7 µ. The Ambient air quality norms prescribed by Central Pollution Control Board (CPCB) for industrial areas limit these values to 100 µg/m3 (SPM) and 60 µg/m3 (RSPM). Such highly polluted in-plant atmosphere of seed spices cleaning-grading industry may cause severe health problems, leading to respiratory diseases among the workers. In order to protect the health of workers engaged in these industries, it is suggested to install the electrostatic precipitator (ESP) device and retrofitting of existing equipment (such that dust levels are within permissible limits) may be considered.

Full textAbstract:
Due to the advances in electronics design automation industry, worldwide, the integrated approach to model and emulate the single event effects due to cosmic radiation, in particular single event upsets or single event transients is gaining momentum. As of now, no integrated methodology to inject the fault in parallel to functional test vectors or to estimate the effects of radiation for a selected function in system on chip at design phase exists. In this paper, a framework, PRogrammable single Event effects Demonstrator for dIgital Chip Technologies (PREDICT) failure assessment for radiation effects is developed using a hardware platform and aided by genetic algorithms addressing all the above challenges. A case study is carried out to evaluate the frameworks capability to emulate the effects of radiation using the co-processor as design under test (DUT) function. Using the ML605 and Virtex-6 evaluation board for single and three particle simulations with the layered atmospheric conditions, the proposed framework consumes approximately 100 min and 300 min, respectively; it consumes 600 min for 3 particle random atmospheric conditions, using the 64 GB RAM, 64-bit operating system with 3.1 GHz processor based workstation. The framework output transforms the 4 MeVcm2/mg linear energy transfer to a single event transient pulse width of 2 μs with 105 amplification factor for visualisation, which matches well with the existing experimental results data. Using the framework, the effects of radiation for the co-processing module are estimated during the design phase and the success rate of the DUT is found to be 48 per cent.

AbstrakTerdapat beberapa jenis limbah kayu dari hasil proses produksi diantaranya adalah limbah serbuk kayu limbah serutan kayu, limbah serpihan kayu, dan limbah potongan kayu. Berbagai upaya dilakukan untuk memberi nilai tambah pada setiap jenis limbah kayu tersebut diantaranya adalah pembuatan kayu laminasi, kayu partikel, MDF, HDF, briket kayu, ornamen kayu, dan lain-lain. Program pengabdian ini memanfaatkan limbah potongan kayu jati menjadi produk papan kayu laminasi dan bekerja sama dengan kelompok industri meubel rumahan Desa Mangunsari di Kabupaten Semarang. Kelompok industri tersebut memiliki limbah-limbah kayu berbagai jenis dengan kuantitas yang tergolong melimpah namun belum ada perlakuan (treatment) sama sekali terkait limbah tersebut selain hanya dimanfaatkan untuk memasak dan dibuang ke lingkungan. Edukasi dan pelatihan dilakukan melalui program ini untuk membantu mitra dalam membuat limbah kayu jati menjadi papan kayu laminasi dengan memanfaatkan alat kerja seperti table saw, hand planner, hand sander, lem kayu, dan bar clamp. Poin penting pembuatan papan kayu laminasi adalah pemanfaatan table saw 8” agar bisa memotong secara presisi mengingat limbah tersebut berupa potongan kayu berdimensi kecil. Poin penting lain adalah pada proses penyatuan setiap potongan kayu dengan proses perekatan (adhesion) menggunakan lem kayu berjenis polyurethane dan pada saat bersamaan dilakukan proses penjepitan (clamping) sambungan kayu tersebut menggunakan alat bantu bar clamp agar proses pengeleman menjadi sempurna.Kata kunci: kayu laminasi, limbah kayu jati, table saw, perekatan, clampingAbstractThere are several types of wood waste from the production process such as wood dust, wood shavings, wood chips, and wood scrap waste. Various attempts were made to add value for each type of wood waste including the manufacture of laminated wood, particle wood, MDF, HDF, wood briquettes, wood ornaments, and others. This program utilizes teak wood waste into laminated wooden board products and cooperate with home-based furniture industry group in Mangunsari Village on Semarang Regency. The industrial group has various types of wood waste with a relatively abundant quantity but there is no treatment at all related to the waste other than just being used for cooking and discharged into the environment. Education and training are carried out through this program to help partners in making teak wood waste into laminated wooden boards by utilizing work tools such as table saw, hand planner, hand sander, wood glue, and bar clamp. An important point in the manufacture of laminated wooden boards is the use of a table saw 8 "in order to cut precisely because the waste is in small pieces dimension of wood. Another important point is the process of assy each piece of wood with the adhesion process using polyurethane type of wood glue and at the same time the process of clamping the wood connection using a bar clamp tool so that the gluing process becomes perfectly.Keywords: laminated wood, teak wood waste, table saw, adhesion, clamping
