This research aims to 1) improve quality of processed herbal product by developing recipe and production procedures 2) develop packaging of processed herbal products in oder to add value exhibit uniqueness and response to customers’ need and 3) transfer technology and body of knowledge about improving products’ quality and developing packaging of processed herbal products. Results from developing of recipe and production procedure of kaffir lime in syrup show that period in boiling kaffir lime before sweetening in syrup has an effect on textures. The suitable period of 5 minutes for boiling kaffir lime results in reducing hardness of kaffir lime core increasing lightness and gaining the highest sensory scores from testers. The suitable amount of fructose syrup used in place of sugar in producing sweetened kaffir lime at 80 percent of sugar weight results in increasing lightness reducing hardness increasing value of red color (a*) and aw when compared with the control group and increasing quality of texture with the highest sensory scores from testers. Quality of microorganism appearance color ordor and texture of sweetened kaffir lime stored in tight-closed polypropylene (PP) bag at room temperature could be maintained for at least 24 days. Regarding satisfactory in packaging prototype it was found that customers were highly satisfied in both overall (4.48) and by aspect of packaging form (4.48) and packaging graphic (4.49). In terms of transferring the technology to a target group of 30 people it was found that trainees were highly satisfied with the technology transfer process (4.56). The highest satisfaction level by aspects was usefulness of service at 4.64 followed by service of staff trainers and service procedure at 4.58 4.57 and

This thesis presents the Power Quality (PQ) analysis of solar power plant 1MW and economic impacts in the distribution power networks. The case study focuses on the penalty fee (fine) from consume the reactive power less than the limit of the Provincial Electricity Authority (PEA) of Thailand. The fine have been charged up to 900000 baht per year. Therefore the thesis studies and purposes the possible solution by analysing the operating function of the inverter (supports reactive mode) installing the adjustable capacitor bank 1500kVar in the Medium Voltage (MV) level and lastly installing the adjustable capacitor bank 1500kVar in the Low Voltage (LV) level. The results shown that the possible solution that reduces the fine is installed the adjustable capacitor bank 1500kVar in the MV. The investment of this installation is cost 1800000 baht with the nominal operation over 10 years. The analysis of financial investment which bases on the Net Present Value (NPV) the Benefit-Cost ratio (B/C) the Pay Back period (PB) is presented the NPV at 4902971 baht B/C 3.72 and PB 2 year (with the Internal Rate of Return; IRR 49.7 percent).

The research aims to study the factors affecting on volume and audit quality of Thai auditor by using empirical research. The population and sample in the research are the CPAs in Bangkok. The research tool are questionnaire with completed response totaling 157 units constituting 21.48% of response rate. The results show that factor that has positive affect with volume of auditing is type of audit office (t = 8.340***) and control variable is experience in auditing task (t = 3.399***) at significant level (α) < 0.001 ; whilst the factors that have negative affect with audit quality are competitive condition in auditing market (t = -2.420*) and volume of auditing tasks (t = -2.227*) at significant level (α) < 0.05.

The purpose of the study on the association between factors affecting environmental information disclosure quality of listed companies in the Stock Exchange of Thailand was to investigate factors which posed impacts on the listed companies in Thailand Stock Exchange using the information from 2007 to 2011. The data applied Multiple Regression Analysis to test the relationship between the dependent variable environmental information disclosure quality and independent variable which included the ability to compete the ability to make profits business liquidity operation period business industry and business size as control variables. The result showed that the ability to compete was significantly related to the quality of the environmental information disclosure. This means that the higher competition the more environmental information disclosure. Regarding the other variables such as the ability to make profits business liquidity and operation period did significantly not relate to the environmental information disclosure quality. Moreover business size had significant positive association with the quality of the environmental information disclosure which means that bigger businesses are more capable to reveal their environmental information than the smaller ones.
