Plant genetic conservation project under the royal initiative of her Royal Highness Princess Maha Chakri Sirindhorn Conducted by Rajamangala University of Technology Phra Nakhon (RSPG – RMUTP)
The ultimate goals of Plant Genetic Conservation Project Under the Royal Initiative of Her Royal Highness Princess Maha Chakri Sirindhorn are development of personnel and conservation and development of plant genetics resources for the advantages of Thai people. The objectives of this project are (1) to promote understanding and awareness of personnel and organization about the importance of plant genetic conservation; (2) to create links between various organizations including government agencies and private sections on virtue foundation; and (3) to build a plant genetics database system that is accessible around the country. The master plan has been distributed over a period of five years. The current operations are in the fifth year of the plan. The operation had three frameworks and eight supporting activities that focused on three resource bases: physical resources biological resources and cultural and wisdom resources. Rajamangala University of Technology Phra Nakhon (RMUTP) realizes the importance and the advantage of these resources. Thus RMUTP has followed the royal initiation with several activities that supported the royal initiative since 2005. These projects were conducted within the frame of the master plan with emphasis on utilization framework as well as establishment of good conscience.
The development of medicinal plant extracts to control Weed germination and growth
Study on the inhibition of germination and growth of weeds in rice fields. The extract from the leaves of Xy/ocorpus gongeticus Parkins and Porinori onomense Hance using fermentation Maceration and extraction techniques for Sequential Extraction with three types of solvent hexane ethyl acetate and methanol. The resuLts showed that Leaf extract of Xy/ocorpus gongeticus Parkins with ethylacetate at a concentration of 2000 -3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of Fl is the highest. Leaf extract of Porinori onomense Hance with hexane at a concentration of 2000 3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of F4 is the highest. Which can be used for research and development of natural products from plants to control weeds in rice fields to develop further research to commercialization
Energy Conservation by the Application of Engineering Principles in a Large Industrial Plant
This article presents the energy conservation of the wood furniture factory in Samutprakarn province by using engineering management technique. The electrical energy of 7408000 kWh per year or 25988055 Bath per year is mainly used in the processes including a heating energy system that is derived from wood scrap. After detailed audit it was found that 8 measures have a potential to improve energy efficiency. 7 measures for electrical energy can reduce the energy of 479837.60 kWh per year and the rest decreases heating energy of 120297.15 MJ/Year or saving the scrap of 9.4 tons per year. In order to assess economic possibility all measure also were considered. The result showed that it was worth to investment. In addition specific energy consumption (SEC) can be improved from 0.57 kWh/ft3 to 0.54 kWh/ft3 or diminishing of 5.26 %
The Development of New Mixed Fiber from Waste Cocoon and Other Plant Fibers
The purpose of this project is to develop the production Process of the blend fibers from the remnants of waste cocoons and plant fibers by the experiment of the handicraft products. The result showed that the remnants of cocoons and 5 types of blends and the other plant fibers were mixed; namely cotton fibers linen fibers ramie fibers pineapple fibers and the hemp fibers. The physical properties were performed as follow: the first breaking strength the breaking strength of the woven fabric from the remnants of cocoons and linen fibers were 155 CN/tex. The second breaking strength of the woven fabric from the remnants of waste cocoons and the Indian hemps were 149 CN/tex. The third breaking strength of woven fabric from the remnants of waste cocoons and cotton fibers were 142 CN/tex. The forth breaking strength of woven fabric from the remnants of cocoons and pineapple fibers was 108 CN/tex. The result showed that the woven fabric from the 5 types of these blends had the potential to be applied in the household textile products
