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.

The study was aimed to investigate environmental conservation conscience and related knowledge of Business Administration undergraduates at Rajamangala University of Technology Phra Nakhon. It was also intended to examine the relationship between the environmental conservation knowledge and the students’ environmental conservation conscience. The samples were 208 fourth year students studying in the second semester of at the Faculty of Business Administration in 2013. The data were collected through the questionnaire regarding the environmental conservation conscience and related knowledge and were analyzed by the frequency distribution percentage distribution standard deviation t-test and One – Way ANOVA. In case of 0.05 statistical differences was found Scheffe’s method was applied for adjusting significance levels in a linear regression analysis to account for multiple comparisons as well as Pearson Product Moment Correlation statistically significant at 0.05 level. The result showed that Business Administration undergraduates highly displayed their environmental conservation conscience and related knowledge and moderately related (r = 0.407) and statistically significant at level of 0.05.
