This study was conducted to determine the effects of plant growth regulators on in vitro propagated plantlets and microrhizome inductions of Curcuma comosa Roxb. for an efficient development of plant regeneration. In vitro sprouted shoots (2 cm length) of C. comosa were incised in longitudinal section and subcultured on MS media supplemented with 3 mg/L BA for shoot multiplication and plant regeneration. Subsequently the regenerated plants were transferred to MS medium with various concentrations of plant growth regulators; BA (1 3 5 mg/L) kinetin (1 3 5 mg/L) and TDZ (0.5 1 1.5 mg/L). The result showed that MS medium supplemented with 3 mg/L BA was the most effective in shoot induction with the significantly maximum average number of 2.11 shoot buds per responding explant. Moreover MS medium supplemented with 1 mg/L BA produced the longest average of shoot bud explants (12.99 cm) while the basal MS medium induced the longest average of root multiplication (6.63 cm). Furthermore microrhizome induction was produced under in vitro conditions derived young shoot buds upon transfer to MS medium containing various combinations of 1 3 and 5 mg/L BA and 30 60 and 90 g/L sucrose concentrations. The optimum combination in the induction of significantly highest average length of both stem (18.32 cm) and root (7.52 cm) multiplication was obtained on MS basal medium supplemented with 1 mg/L BA and 30 g/L sucrose for 4 weeks. Although microrhizome formation was not produced by the different amount of BA and sucrose in induction medium starch accumulation was found at the base of the stem explants cultured on MS medium containing 60 and 90 g/L sucrose concentrations. Additionally in vitro propagated C. comosa plantlets through microrhizome induction were grown under greenhouse conditions for 4 weeks and further developed into normal plants resulting in successfully high survival rates of 66 – 100% in the cultivated C. comosa.

This study Development of cultural tourism routes in Phetchaburi Municipality have a purpose to study the basic information on the development of community tourism routes and to create cultural tourism routes in Phetchaburi municipality. The research employed a qualitative research The key informant groups are community leaders academics village philosophers community staff. The research tool was an open-ended questionnaire for in-depth interviews and a focus group. The results of the research revealed that the area in Phetchaburi municipality is a complete cultural base area. There are cultural attractions that are interesting including religious sites ancient sites traditions lifestyles.

The purpose of the Environment Control System for radish with Internet of Things project is to control the environment of radish cultivation in a planting house. The working process of this project is separated into two parts. The first part hardware control is to control temperature moisture and illustrated the working status on LCD. The second part software control is collected data from all sensors and then published results on the website via MQTT protocol. The Environment Control System for radish with Internet of Things project is evaluated by measuring the value of temperature and soil moisture from the system compare with the value from reliable instruments. The test results show that the system can measure the temperature and soil moisture correctly. Moreover the software function of the system has fulfilled the requirements.

The purposes of this research were to study the potential of creative tourism resources and the creative tourism management model of Khu Bua community Ratchaburi. This research was qualitative. The research tools were the in-depth interview and focus-group. The target groups were local people consisting of community leaders entrepreneurs merchants and government officials working in the area and tourist groups. The accidental sampling was applied for selecting tourist groups and the purposive sampling for other key informants. The data was analyzed by content analysis. The research results were as follows: 1. It was found that Khu Bua community’s potential for creative tourism were community history the ancient city area of Ban Khu Bua Thai-yuan cultural identity and community readiness. 2. As for strengths weaknesses opportunities and obstacles of Khu Bua Communitys Internal and External Environment the community strengths were famous woven fabrics ancient tourist sites occupational groups’ product development and promotion learning centers and an easily accessible location. The community weaknesses were a lack of career knowledge skills and experiences; no land of their own; without descendants’ awareness of their roots as well as no successors to the community culture. The community opportunities were more communicational channels the official tourism promotion policy and the increase of cultural tourism trend. The community obstacles were consumerism social change and lack of integration and linkage between central and local authorities. 3. Opinions and demands of tourists towards creative tourism in Khu Bua community were: 1. Due to the community tourist attractions information most tourists got the information from online social media. 2. According to tour time the tour in the community took no more than half a day. 3. As for the knowledge and understanding of creative tourism of the community most tourists replied that they participated in various activities the community planned. 4. Due to creative tourism activities the demand for the community activities mainly focused on learning about the Thai-yuan identity and local ancient sites. 5. According to the problem or suggestion for the creative tourism of the community most tourists suggested that there should be various channels directly informed by its responsible agency. 4. There were two models of creative tourism management for Khu Bua Community Ratchaburi including (1) tourism models changing from high-class cultural products to everyday cultural ones and (2) tourism models allowing tourists to participate in local community tourism activities. As for the community creative tourism management there were two phases: the experience and product creation phase and the product delivery and service phase.

The application of integrated energy use in the agriculture sector It is presented in the form of using renewable energy from solar energy to produce electricity to use in conjunction with other sources of electricity such as generators or electric power systems. Using solar panels or solar cells the size and number of panels does not exceed 300 watts 4 panels and the electrical system of the electrical system. Supply electric power to the water pump size does not exceed the rating of 1500 watts 220 volts. Solar power supply systems alone may be affected by weather conditions or electrical power supplies. Including the quality of electricity obtained from solar energy and will result in the water pump not working efficiently. Therefore the application of solar energy by using a power supply system from 2 sources by using a hybrid inverter device to select the power supply from the solar cell is the main power and the power supply from the memory system is the backup power. Therefore a research project on the application of solar water pumps in a mixed system for agriculture is proposed to increase the efficiency of electric power distribution. This application of solar water pump hybrid system for agriculture when used with water pumps can normally help to save electricity and can also use solar energy instead of using electricity to pump water. Let the water pump and can work efficiently.
