The pre-finishing, finishing, and dyeing processes applied to the fabrics are carried out at high temperatures, in acidic or alkaline environments. Conventional metalized yarns which are produced by metalized yarn companies cannot resist these conditions that change due to raw material type. Metalized parts exfoliate when exposed to these conditions, and shiny appearance disappears completely. Therefore, in order to be a solution for this problem for the products that the use of metalized yarn is required, companies produce fabrics by using metalized yarns that were colored in bobbin form and choose proper application conditions for metalized yarns. However, because this solution increases production time and workmanship, the production costs and the product’s sale price increase correspondingly. The use of metalized yarns with untreated fiber is more advantageous than the method mentioned above for companies in terms of both cost and ease of production process. For this purpose, in this study, the resistance of metalized yarns that were produced by using lamination technique was tested against the chemicals which metalized yarns can be exposed during textile finishing processes, and the appearances of the fabrics were evaluated. Because metalized yarns are commonly used in the production of cotton and polyester fabrics, finishing processes that are applied to cotton and polyester fabrics were applied to metalized fabrics in a textile finishing laboratory. Then post-processing appearances of fabrics were evaluated subjectively.

Constraints are activities that prevent companies from carrying out production activities. Along with the increasingly competitive world economy today, industrial companies are required to be more sensitive in anticipating constraints that occur both internally and externally. These constraints must be considered by the company because it can hamper the production process which has an impact on production costs as well as sales volumes which ultimately cause losses to the company. One tool that can identify constraints of a company is the Constraint Theory. This study aims to find out what constraints occur in the production process and the impact of these constraints on production costs. The method used in this study is descriptive. The results of this study are internal constraints are engine damage and external constraints are delays in the delivery of raw materials. The impact of these constraints on production costs is the loss of raw material costs and an increase in factory overhead costs.Keywords: Constraints, Production Cost, Theory of Constraint

Development of competitive businesses have triggered changes in the various methods of business management to streamline labor costs, overhead costs and raw material costs in improving product quality. Manufacturing companies are in a period of dynamic transformation that requires the manufacturers to always expand its business to survive and have strong competitiveness in addition to the company must have a strategy for its business organization, strategies must be developed by the company in addition to developing the company's products also must develop the data processing. Every company should be able to do if financial data appropriately and accurately to support the company's business decisions. For that a corporate leader needs a tool to control the company, the tool is a useful accounting information system to present the report production costs properly. Hopefully, by the system of all the activities of the company can be run according to plan and to minimize deviations or errors that occur which could harm the company.Object of research chosen by the authors is the company CV Surya Pratama Gemilang, a medium-sized manufacturing company that produces a variety of bacterial decomposition and laboratory equipment. The company has a systematic record system and computerized production and there are some systems that are still made manually as demand for raw materials from the production to the warehouse with a waffle sometimes only just though the procedure had to use a memo for taking raw materials from the warehouse. In doing production company CV Surya Pratama Gemilang processing raw materials into finished products based on processes that make the production process according to the requirement or determination of the barn, so when the warehouse inventory is less than the policy-setting in the warehouse, the company started production to meet the needs of the provisions in the warehouse.

In the production process at PT X, such as casting process, required raw material in the form of casting sand. The sand transport process is done by a machine called a Bucket Elevator. The current condition of Bucket Elevator at Plant 2 PT X had some problems on its design due to the initial modification process to the machine that were deliberately done in order to ease the process of troubleshooting and repair on the machine to adjust the height of the drum shaft supported by the bearing, however, the modification causes a sand leak that impacted the lifetime of the bearing. The damage that occurs to the bearing of the Bucket Elevator can slow the production process at PT X down, which lasts between 120 hours to 134 hours per week. Therefore, it is necessary to modify the design of the Bucket Elevator machine in order to stop the sand leakage and be able to work optimally. The design modifications made, are changes to the shaft height adjusting mechanism of the Bucket Elevator 536 drum machine by providing a lock to minimize the leakage of sand that occurs and replace the bearing type to the type that is equipped with a seal to prevent the entry of sand into the bearings. The result of this modification can extend the lifetime bearing, thereby reducing production costs due to bearing replacement, and easing the troubleshooting and repairing process of the engine to adjust the height of the drum shaft supported by the bearings.

In the mountainous canton Grisons, much visited by tourists, the forest has always had an important role to play. New challenges are now presenting themselves. The article goes more closely into two themes on the Grisons forestry agenda dominating in the next few years: the increased use of timber and climate change. With the increased demand for logs and the new sawmill in Domat/Ems new opportunities are offered to the canton for more intensive use of the raw material, wood. This depends on a reduction in production costs and a positive attitude of the population towards the greater use of wood. A series of measures from the Grisons Forestry Department should be of help here. The risk of damage to infrastructure is particularly high in a mountainous canton. The cantonal government of the Grisons has commissioned the Forestry Department to define the situation concerning the possible consequences of global warming on natural hazards and to propose measures which may be taken. The setting up of extensive measurement and information systems, the elaboration of intervention maps, the estimation of the danger potential in exposed areas outside the building zone and the maintenance of existing protective constructions through the creation of a protective constructions register, all form part of the government programme for 2009 to 2012. In the Grisons, forest owners and visitors will have to become accustomed to the fact that their forests must again produce more wood and that, on account of global warming, protective forests will become even more important than they already are today.

The bought sugar in the processed raw material (either beet or cane) comprises a high financial value and may contribute to somewhere around 50% of the white sugar production costs. It is therefore of the utmost importance to minimize sugar losses along the process and produce as much white sugar as possible from the raw material. This paper explains the principle of technical accounting as tool to control sugar extraction and losses in beet sugar manufacture. The sugar mass balance used to calculate the overall sugar extraction yield, as well as several simple calculations proposed for estimating the different sugar losses (like e.g. extraction (diffusion) losses, infection losses, sugar losses in molasses, etc.) in the subsequent process steps will be explained in detail. Proper technical accounting is considered indispensable for continuous process control and process improvement in pursuit of best-practice operation and cost-leadership.

AbstractHigh-consistency processing of fibrillated cellulose materials is attractive for commercial applications due to potential for lowered production costs, energy savings and easier logistics. The current work investigated structure–property relationships of fibrillated cellulose suspensions produced at 20% consistency using VTT HefCel (High-consistency enzymatic fibrillation of cellulose) technology. Morphological examination of the fibrillated materials revealed that enzymatic action on the cellulose substrates was not a direct function of enzyme dosage but rather was dependent on the raw material composition. Furthermore, shear viscosity of the HefCel suspensions was found to decrease with increasing enzyme dosage while the water retention increased. The shear viscosity followed power law relationship with the power law index varying in the range 0.11–0.73. The shear-thinning behavior decreased with increasing consistency. Moreover, suspension viscosity ($$\upmu$$ μ ) was found to be highly dependent on the consistency ($$\mathrm{c})$$ c ) as $$\upmu \sim {\mathrm{c}}^{\mathrm{m}}$$ μ ∼ c m , with $$\mathrm{m}$$ m ranging from 2.75 to 4.31 for different samples. Yield stress (τy) of the HefCel suspensions was measured at 7 and 10% consistencies. The performance of the fibrillated cellulose grades in a typical application was demonstrated by casting films, which were characterized for their mechanical properties. Graphic abstract

As Earth’s fossil energy resources are limited, there is a growing need for renewable resources such as biodiesel. That is the reason why the social, economic and environmental impacts of biofuels became an important research topic in the last decade. Depleted stocks of crude oil and the significant level of environmental pollution encourage researchers and professionals to seek and find solutions. The study aims to analyze the economic and sustainability issues of biodiesel production by a systematic literature review. During this process, 53 relevant studies were analyzed out of 13,069 identified articles. Every study agrees that there are several concerns about the first-generation technology; however, further generations cannot be price-competitive at this moment due to the immature technology and high production costs. However, there are promising alternatives, such as wastewater-based microalgae with up to 70% oil content, fat, oils and grease (FOG), when production cost is below 799 USD/gallon, and municipal solid waste-volatile fatty acids technology, where the raw material is free. Proper management of the co-products (mainly glycerol) is essential, especially at the currently low petroleum prices (0.29 USD/L), which can only be handled by the biorefineries. Sustainability is sometimes translated as cost efficiency, but the complex interpretation is becoming more common. Common elements of sustainability are environmental and social, as well as economic, issues.
