This research aimed to study the optimum factors affecting the quality of gold plating process to enhance OTOP knife products of Ban Mai knife forgers village. This study focused on application of AISI 5160 steel and the 24k gold plating process.In the experiment three samples of plating currents were observed; 10 12 and 14 volts each at 30 60 90 120 150 seconds and 180 seconds respectively. The study found that applying the electric currents in gold plating at 12 volts for 120 seconds gave the best results for the gold color and thickness by giving the thickness of the gold surface at 33.82 micron and the color value between L*=88.72 a*=4.45 and b*=78.58. Moreover the gold dispersion was consistent throughout the workpiece. From applying the electric currents in gold plating at 10 volts it lessened the thickness of the gold plating which made the gold plating look uneven. From applying the electric currents in gold plating at 14 volts it increased the thickness of the gold plating which resulted in a dull or burned finish from over-plating. In comparison the cost of the knife before plating with gold costs only 30 baht per piece while the cost of the knife after plating with gold costs 99 baht per piece. In conclusion the daily sales of a product increase from 50-60 items per day to 60-75 items per day which also resulted in increased revenue and profitability from 1500-1800 baht per day to 5940-7425 baht per day on average.

This research was studied and transferred the biogas production technology with the community participation using anaerobic dry fermentation system from agricultural residues. The production of renewable energy for replacing LPG in household cooking of Koh Khan Sub-district community Cha-Uat District Nakhon Si Thammarat Province was carried out. The efficiency of the biogas production from different co-digestion material with fresh cow manure was studied for 45 days. The experiment 1 bananas and papaya and the experiment 2 rice straw and coconut meal were used for fermented materials. It was found that the system using rice straw and coconut meal as a fermented material had a higher potential than using bananas and papaya. The system produced averaged biogas of 150 L/d and an average methane content of 67.68% respectively within just 15 days after start-up. While bananas and papaya as fermented materials took more time with more than 30 days after start-up the system. The system produced averaged biogas of 120 L/d and an average methane content of 64.64%. For usability test It was found that 150 L of biogas could continuously cook for 45-60 minutes. The 85% of the technology transfer recipients regarded that the knowledge gained as practical and reduced household expenditures. Additionally the system can produce biogas for a long time without adding new fermented materials. Therefore this biogas system could be applied to local agricultural waste for biogas production which can be expanded to other areas.

Guidelines for designing public spaces and land traffic areas in the landless village Bang Chan Subdistrict Khlung District Chanthaburi Province This research is to propose guidelines for the design and construction of public spaces for various activities and areas for use in land traffic in the landless village. To create a village identity in both the physical environment and the way of life of the people in the village. This can be a selling point for sustainable tourism and also to improve the quality of life of the people in the village providing space for recreation and joint activities within the village. This will encourage strength within the village and lead to a livable village. By the way of conducting research It starts with collecting data which is divided into 2 steps: document gathering and related research. To build a body of knowledge on issues related to the research topic. And field data collection To obtain information based on the reality of the area that is current. The data was then analyzed based on the research objectives. Which consists of Physical characteristics of the environment and village characteristics and forms of existing public spaces within the village. And the nature of the use of public spaces of the people in the village After that conditions and factors influencing the design of public spaces and land traffic areas within the village were determined. And to establish guidelines for the design of public spaces and areas for land traffic within this landless village according to the above conditions and factors. To be consistent with the physical characteristics of the area and the public space behavior of the people in the village. From conducting research it was found that Guidelines for designing public and land traffic areas in the researched landless village It can be summarized as two main points to consider the first being the public space within the village There is only one place in the landless village that has been conducted this research which is a shrine at the entrance of the village. It consists of the area of the shrine building. Public restrooms for visitors And a multi-purpose outdoor patio area Which if there will be additional public space construction in the village It should be in a close position and can be connected primarily to the original shrine area. This will lead to better support of social activities within the village than by distributing the area to other parts of the village. This may cause public areas to be inactive as they should and may result in them becoming wasteful areas in the future. Coupled with the immediate vicinity of the shrine in front of the village entrance There is a wooden bridge across the brackish water canal. Which was used as a walkway to and from each other between houses on both sides of the canal And is also considered a destination that is beautiful and unique in the village. This is another factor that will help promote the appropriate public spaces located in this area in terms of the quality of the public spaces. And in terms of accession and usability. For the second issue of guidelines for designing public spaces and land traffic areas within the landless village the study should be taken It is a matter of land thoroughfare that is used as a main pedestrian route to connect the front of each house within the village. May be constructed from precast concrete slabs bamboo other types of timber that can be easily procured locally. Or made from other materials not mentioned here But it must be materials that will not affect the environment in the area both during the process of material transportation to the area construction process use process after construction is completed. Until the process of maintenance reuse or disposal after the end of their service life.
