This research had an aim to develop an autoclave for using in natural dyes extraction and dyeing process. The autoclave used the stainless steel as the major material what it was a noble durable material and good resistance for the chemical used in the processes. The achievement results showed by the comparison data between the conventional process and the development using autoclave in term of extraction efficiency deep of shade (K/S) time equivalent process time and amount of gas consumption saver. The knowledge from the research would transfer to the target group at Bann Yang Nam Klad Tai Phetchaburi province. The results were following as 1. For the extraction process: the extraction process using 100oC for 45 min. They obtained product was the same dye quality but the autoclave process was smaller water evaporation as 26.71% whereas the conventional process was 41.99%. 2. For the dyeing process: All condition from the autoclave using make a deeper dye shade (K/S) than conventional process. The dyeing time equivalent as 15 minutes to make the depth shape via autoclave process as alike the conventional process for 45 min. 3. Saving time and gas consumption: the autoclave process could save 66.67% time process and 88.99% amount of gas consumption. 4. The Complacency for knowledge assignment: the satisfaction level in the content time and period was good. Furthermore the utilization the instructors and the value obtained were excellent. This research accomplished the study objectives. The results were not only corresponding to energy conservation but them also reducing the chemical toxic and pollutant vapor inhalant to the worker.

This paper presents the design of automatic watering system using sun tracking as an energy source .The objective is to design the automatic watering system for fruits grown in both areas without electricity. The solar panel can be moved along the direction of the sun cover an altitude - azimuth dual axis as an energy source of the system. The 20 longan trees are used in the experiment. The DC motors and the solar panel is controlled and rotated by the microcontroller to the position of the maximum light intensity. The watering system section will use a technique to measure the soil moisture sensors ECHO2-20 with real time PC based monitor system by Visual Basic Studio. As for the experiment results it was found that the energy stored by the developed solar tracker increased to 17.72 percent in comparison to a solar panel fixed installation. The watering appropriate soil moisture content is 12 percent and stops at 25 percent resulting for the garden moderators to save time and labor.

This paper presents the development of Automatic Malfunction Warning System (AMWS). The objective is to improve the performance of 5-kWp Grid-connected PV system with real time PC based monitoring system installed at Rajamangala University of Technology Suvarnabhumi Nonthaburi Thailand. The system is able to measure electrical parameters and air condition with real-time display. The AMWS comprises of hardware and software. The software was developed by LabVIEW. The AMWSs function is to monitor important equipment in the PV energy system. If there is a malfunction or any detected faults the AMWS would directly warn the operator of the PV energy system instantly. Results showed that the AMWS can complete programmed operation according to specified condition. The AMWS can send the right details and the cause of malfunction by SMS and E-mail every time the system did not work properly. The benefit of this system is that the operator can get the system to run properly and fix problems in a short period of time

The objective of this research was to study personal and marketing mix factors affecting decision on choosing an automobile repair service of customers in Bangkok. A close-ended questionnaire was utilized as a research tool for collecting data from 400 car owners in age range of 18 to 60 years old who used to have their cars f ixed at automobile repair garage in Bangkok. Results showed that consumers with different genders had different decisions in choosing automobile repair service at statistically signif icant level of 0.05. However consumers with different ages marital statuses occupations and monthly incomes had no difference on the decision for choosing automobile repair service. Additionally marketing mix factors of product and service people process and physical evidence had signif icant inf luence on customers selection of automobile repair service at the level of 0.05 while the marketing mix factors of price and distribution channels had no signif icant inf luence on customers choosing of automobile repair service. Factors affecting the decision on choosing automobile repair service of customers most was the marketing mix factor of people followed by product and service physical evidence process of service and promotion respectively

The research was aimed at studying 1) fuel energy saving of automobile drivers in Nonthaburi province 2) a correlation between cause and effect on fuel energy saving of automobile drivers in Nonthaburi province and 3) a model made for assessing fuel energy saving of automobile drivers in Nonthaburi province. The questionnaires were constructed as a tool for collecting data from 2389 automobile drivers who had been getting their car filled in gas station in Nonthaburi province. The statistics used for analysis were SPSS version 17.0 with frequency distribution percentage arithmetic mean K related samples and path analysis. The research finding indicated that the 98.06 percents of automobile drivers in Nonthaburi province had knowledge about fuel energy saving the 87.99 percents had agreeable attitude towards fuel energy saving and the 80.59 percents had operated fuel energy saving. They all had different levels of knowledge attitude and operation. It showed that the automobile drivers with knowledge and agreeable attitude didnt sometimes put it into operation and they sometimes had disagreeable attitude in spite of having knowledge. The result of hypotheses tests at the statistical significance of 0.05 showed that the types of fuel energy used in the car a change of types of fuel energy used in the car knowledge provided about fuel energy saving in the car knowledge and attitude towards fuel energy saving in the car correlated with fuel energy saving of automobile drivers in Nonthaburi province. Moreover a model made for assessing fuel energy saving of automobile drivers in Nonthaburi province was
