This research aims to reduce waste in the production process to meet the target to find ways to prevent defects occurring in the curing process and to improve preventative measures available today. The waste found in the curing process label the edges are blamed blistering edge under inflated tires cover on low. After brainstorming to find factors that affect the defect by using techniques Six Sigma (Six Sigma).The work five main steps in performing a job defining the problem measuring analyzing problems improved control and severity surveillance and monitoring disorders of the process. It was found that the raw materials are the main parameters that cause much waste as possible. Therefore we have developed an approach to improve the material by adding a preliminary inspection and design documents to determine work procedures. The benefits of this research can reduce the waste that occurs in the curing process of the target by reducing the rate of 8.0 % an average of 7.3% in a survey from January to May 2557 is an average rate of 6.0% In a survey in June 2557 equivalent to saving manufacturing cost 135045 baht per month. The rate of decline is likely to be quite good that make employees feeling and effort to cooperate in the reduction of waste in the production process.

The objective of this research is to develop a technology management system for industrial Fabric Pretreatment Dyeing and Finishing factory to resolve existing problems caused by manual input. Firstly this research was performed to study the current work-in processes data. After that these data were analyzedranked and grouped for designing and developing a customized oracle database by implementing SQL on a UNIX server. Finally the new system was integrated barcode technology for connection to facilitate works. Before the renovation to input data by an employees it makes to delay time 1440 minutes from actual manufacturing data. The result represent at 260.67 unit/month as well as newly application of barcode technology. According to this system application it has been found that the manufacturing data in production process are real-time monitored. The result of the research can be increase at 94.42 unit/month as well as reduce expenses on documents above 10000 Bath/month. In addition the operator could also be reduce from 4 to 0. Including enhanced with barcode technology can also facilitate communication with customers making business competitive sustainable future.

At present a problem found in the soft candy producing process in the food producing department of Company Case Study is time-consuming roller washing process due to an ineffective washing process. A roller is washed one by one from a total of 10 roller (a set) in one machine. As a result the operation rates of other producing processes have been forced to delay. The objective of this research is to resolve the problem found in the process of roller washing by designing a machine for washing a set of roller per time. The research begins from examining design concepts of roller washing machine from patents and the current quantity of water and stream used for washing before conducting design of a new soft candy type roller washer machine. And eventually the efficiency of new roller washer machine is compared with current one. The findings indicate that the newly developed design can reduce washing period from 24.48 minutes/set to 5.56 minutes/set and increase operation time by 18.92 minutes or accounting for 77.28 percent. Meanwhile water quantity used in the process is reduced from 124.82 liters/set to 28.35 liters/set and stream quantity used in the process is also contracted from 0.83 kilogram/hour/set to 0.18 kilogram/hour/set. This reduction can save expenses equal to 28795 baht/year. As the budget for making new roller washer machine is 53000 baht and payback period is only 1.84 year.

The objective of this research is to improve for material procurement decision support making process by using Lean Concept. The research methodology studied purchasing procurement and whole of production in local country of case study by making Value Streaming Mapping (VSM) calculated of production standard time set buffer time kept inventory and suitable supplier’s capacity. Finally used all data for design and develop computer program into support analyze and follow up delivery goods system to customer. Result of research found this new development program could increase delivery goods to customer efficiency by response with material preparation can improved average On Time Delivery rate at 94.55% and increased productivity from 966 to 1125 pcs/day; therefore case study had well increased local purchasing procurement efficiency reduced purchasing cost to 2.27 million Baht/month reduce Fuel cost at 46225.08 Baht/year on average and reduce greenhouse gas at 4.117 TonCo2e per year on average. They can support highly competitive and rapidly changing of electrical and electronics industrial to sustainable in the further.

Earthworms play an important role in the cycling of plant nutrients turnover the organic matter and maintain the soil structure. The decomposition of different types of organic substrates (household waste agro-residues and sludge) is able to be turned into valuable vermicompost. The percentage of nitrogen phosphorous and potassium in vermicompost was found to increase on different types of organic waste. Vermicompost is a finely divided peat like material with high porosity good aeration drainage water holding capacity microbial activity enriching of nutrients and buffering capacity thereby resulting the required physiochemical characters congenial for soil fertility and plant growth. Vermicomposting is a low-technology environmentally-friendly process used to treat organic waste. Moreover certain species of earthworms are used to enhance the process of organic waste conversion and produce a better end product. The Earthworm species Pheretima peguana were especially used in Thailand.
