CO2 emission of rail transportation system plays more important role including the expansion of BTS route that consume the energy and emit CO2 gas more and more. The purpose of this research was to find out amount of CO2 emission from travelling by BTS train and determine specific CO2 emission per product in the form of gCO2e/passenger/km then forecasting on CO2 emission from BTS operations. Research process was initiated from collecting monthly data on ridership distance and electricity for 55 months continuously then regression analysis CUSUM and time series analysis were used for prediction and analysis of CO2 emission. The finding indicated that BTS’s specific CO2 emission was 24.7 gCO2e/passenger/km. Forecasting CO2 Emission from BTS result that Winters Exponential Smoothing Method is most accuracy then Double Exponential Smoothing Method Trend Analysis Method and Decomposition Method respectively. The result of these analysis could be used to calculate carbon footprint from staff travelling by BTS train and promote people to use public transport by government as sustainable transportation concept.

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.

The objectives were to study microbiological hazard of Khao kluk ka pi for school food service risk assessment and critical control points (CCP) according to HACCP principles.The production of Khao kluk ka pi had the improper hygienic practice. Thus TPC counts were found in shallots coriander and chilli at 1.9×106 3.2×107 and 5.9×106 cfu/g respectively and found E. coli in chopped coriander more than 1100 MPN/g. The TPC S. aureus C. perfringens Salmonella and V. parahaemolyticus were not detected in cooked ingredients. The number of TPC in Khao kluk ka pi held at ambient temperature for 0 2 4 and 6 hours were founed an increase from 1.2×106 cfu/g to 7.6×106 1.8×107 and 3.4×108 cfu/g respectively that was as a result of the uncooked ingredients and mixing process. The microbial numbers were increased when this food was held for a long time before serving. The CCP of Khao kluk ka pi production were indicated at the process of washing raw vegetables cooking process and holding cooked food at room temperature for a long time before serving.

This research aims to 1) set up analysis procedures and define the Information. 2) to Apply DMAIC to the information. 3) to comprehend the number of information models. 4) to Study the acceptance of Information models. And 5) to analyze the acceptance of the Six Sigma Quality indicators . Sample group consisted of 116 people included high-ranking executives middle executives specialistsand operational executives. The simple random sampling from the population of 424 people. The tools used in this research comprise the information models content correctness assessment forms acceptance assessment forms the information models and indicators. The results have shown that 1) the process for analyzing and defining the information consists of four procedures 2) the Information models can be formed with the five steps of DMAIC 3) applying DMAIC has shown that 42 models 4) The number of the populations accepting the models is higher than that of those who do not accept them with statistical significance at .05 level. And 5) The number of the respondents accepting the indicators is higher than that of those who do not accept them with statistical significance at.05 level.

Thesis is the development of radio-controlled lawn mower which can move and cut the grass in the desired environment and dangerous to human. The objective is to develop a radio-controlled lawn mower. The results showed that the rate of fuel consumption of controlled lawn mower in to cutting grass. The height of the grass at 6 8 and 10 cm. It has the average fuel consumption is 113 117 and 123 ml. The average time in the mowing is 6.6 8.01 and 9.69 minutes
