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 purposes of this study were to costs and fees of solid waste management and to provide resolutions towards solid waste management of Omnoi City Municipality. The data were collected by using financial data during 5 years from 2008 to 2012. Then the data were calculated to figure out the costs of solid waste management divided by solid waste management-related cost and non-solid waste management-related cost. The results found that annual solid waste generation rate of Omnoi City Municipality was 0.53 ton/person or 0.65 ton/household. The annual average quantity of solid waste was 27327.26 ton/year and the annual cost of solid waste management was 2084.62 Baht/ton. The costs were separated into the solid waste management-related cost including the cost of main department responsible for solid waste collection service as follows; 1) direct labor 493.79 Baht/ton 2) direct materials 170.83 Baht/ton 3) production cost 231.07 Baht/ton and 4) cost of solid waste management 477.95 Baht/ton. Moreover the non-solid waste management-related cost or the cost allocation supported by other departments consisted of Administration Department and Council 95.78 Baht/ton Office of the Municipal Clerk 308.43 Baht/ton Division of Technical Services and Planning 93.49 Baht/ton Division of Finance 137.25 Baht/ton and Division of Sanitation and Environment 76.03 Baht/ton. Omnoi City Municipality could gather the fees of solid waste management about 152.32 Baht/person/year or 186.61 Baht/household or 290.31 Baht/ton or 13.93 percent of the cost of solid waste management. According to the cost calculation of solid waste management the supporting departments associated with the solid waste management should allocate sufficient budget and provide the cost data which would be useful for administrators at all levels to measure and improve performance. Furthermore additional policies related to the solid waste management should be defined to reduce the management cost and quantity of solid waste. The responsible departments should also promote people’s understanding and realization of duty to pay for fees of solid waste management.

The objective of this study was to investigate Management of Credit Risk for Sustainability of Army Welfare Department Savings and Credit Cooperative Limited. The data were collected through the interviews with executives such as division directors or vice directors who were requested to provide guidelines how to sustainably manage credit risk.

The study was aimed to investigate the production of banana fiber that was suitable for decorating handicraft basketry examine its effectiveness develop decorative handicraft materials for basketry from fibrous layer on the trunk of the banana tree and promote the obtained knowledge in the community of Plasticseeroong Baanmor Promburi District Singburi Province. The research result could be summarized that the most appropriate production process of dry fibrous layer on the trunk of the banana tree mixed with fibrous layer of paper mulberry was done through mechanical process. After bleaching the mixed fibrous layer was stirred by Hollander beater with the proportion of wet fibrous layer and water at 1:40; 10% of dry of paper mulberry was boiled for three hours in sodium hydroxide at 100degree Celsius then bleached with 1.5% of hydrogen peroxide with 4% of the dry fibrous layer weight at 90 to 95 degree Celsius for two hours. The mixture of wet fibrous layer on the trunk of the banana tree with wet fibrous layer of paper mulberry was 70:30 which was considered appropriate for decorating handicraft basketry. Concerning the examination of mechanical properties of banana tree fibrous layer according to the standard of TAPPI T it was found that the folding endurance of paper value was 144 (N. m/g); the tensile strength value was 32.16 (N. m/g); the tear resistance value was 26.56 (mN.m2/g); and the bursting strength value was at 1.94 (KPa.m2/g). The fibrous layer obtained from on the trunk of the banana tree was fabricated into decorative basketry materials for example flowers palm leave hats flower key chains bags and paraffin coated flowers for bamboo boxed. The attendants’ satisfaction on the training of the production of decorative handicraft materials of basketry from fibrous layer on the trunk of the banana tree to 30 members of the community of Plasticseeroong Baanmor Promburi District Singburi Province concerning the training service speakers training procedures facilities and training benefits was at high level (90.67%) and at average level (9.33%).

The objectives of this study were to investigate communities confidence in their local leaders the locals awareness and factors affecting peoples participation in the water quality management. Data were collected from interviewing 400 households and analyzed with a Logit model. Results showed that the samples were well aware of water quality problems. The communities confidence in their local leaders was in a middle level and the communities’ participation in common activities was low. Factors that affected communities participation in water quality management were confidence in local leaders membership of the conservation groups education level and awareness of water source problem respectively.
