Young coconut shells are a byproduct after processing coconut juice which can be used to produce a solid-fuel. This fuel from the coconut shell is an alternative source instead of using firewood or charcoal made of timber in the natural forest. The solid-fuel from young coconut shells was prepared by using a wet glue powder as a binder then was compressed by using a briquette machine. The black coconut briquette was stable after exposure to the sun. The average of the briquette combustion rate was at 11.24 g /min. There is no eruption smut smoke and odor by using the young coconut shell briquette yo start a fire. To sum up a young coconut shell has a high potential as an alternative biomass material for producing a briquette especially for commercial. This solution can increase the reduction of haze weather in the sight of solid waste incineration and also global warming.

An optimal of walking path to travel in Lopburi City was the shortest distance of path anduses least travel time. The research methodology used the survey of 10 real locations togetherwith viewing satellite maps and diagrams from Google earth.com for graphing and weighting of edges (distance time). The result analysis used the basic ideas of graph theory by finding the path that has all the vertex and used the idea of matrix by finding the adjacency matrix. The result of the research shown that an optimal of walking path to travel in Lopburi City that is to be as following Wat Puen Wichayen House Prang Khaek Somdet Phra Narai National Museum Lopburi Wat Phrasi Rattana Mahathat Wat Bandai Hin Wat Inthra Wat Nakorn Kosa Phra Kal Shrine Phra Prang Sam Yot with a total distance of 2090 meters in 25 minutes.

The study of the requirements for opening thinking and problem solving course uses a questionnaire method from a sample of 160 people from all 9 faculties. Using a QR code questionnaire/link with students of Rajamangala University of technology Phra Nakhon. To analyze the basic statistical results (percentage mean standard deviation). The research results were found that the student’s opinion on the teaching of thinking and problem solving course had a total average of 4.10 (high opinion level). By means of descending mean as follows problem solving had the highest average value at 4.26 followed by creativity thinking future thinking applied thinking critical thinking analytical thinking strategic thinking analogy thinking integration thinking synthetic thinking conceptual thinking and critical thinking.

This research aimed to study the optimum conditions for making raw lime from shells which consisted of 9 conditions: calcined at three levels of 700 800 and 900 degrees Celsius for 1 2 and 3 hours. Calcium element content in raw lime using X-ray fluorescence (XRF) measurement and structural analysis of calcium compounds by X-Ray Diffraction (XRD). The research results were found. 1. Optimal conditions for making lime mortar are temperature 800 degrees Celsius duration 2 hours. The physical characteristics of raw lime are white and porous. 2. The calcium content from the shells calcination at 800 degrees Celsius for 1 2 and 3 hours was 98.22% 96.70% 97.89%. 3. Changes in the calcium compounds of raw lime obtained by calcining the shell at 800 degrees Celsius for 1 hour were mainly found in the form of calcium carbonate (CaCO3). At 2 3 hours calcium carbonate (CaCO3) is mostly converted to form calcium hydroxide (Ca(OH)2)compound calcium oxide (CaO) compound is formed.

The research team aimed to develop the cracking and extracting processes for Ganoderma lucidum (Red Lingzhi) spores and transfer the technology in the form of soap bar and liquid products together with the cracking and extraction process to the community at Farm Haid Klang Ban in Pathumthani Province. From the study since higher more bioactive compounds found in the aforementioned Ganoderma (Lingzhi) spore extracts over its basidiospore itself the optimized breaking and extraction procedure were composed of freezing at -20oC for 2 days bead beating for 5 minutes and then spore fermented with Lactobacillus spp. at room temperature for 24 hours. The processes could provide more than 65 percentages of the spore fracture efficiency and obtain more active substances such as polysaccharides and triterpenoids Moreover the spore extraction process was required by shaking in ethanol dissolved in distilled water at the ratio 80:20 for 2 hours. The obtained bioactive Lingzhi spore extracts as one active ingredient was added into the saponification process to make soap bar and liquid product. It was found that the soap products could create satisfaction and good feedback from high-level consumers of the farm community in Pathumthani Province. The research should therefore be successfully applied in the form of commercial red lingzhi extract soap in the manner of integration of science and community with knowledge of efficient Red Lingzhi spore cultivation and separation. It can help the development of community enterprises can bring up sustainable economic development in the country in the future.
