การเฝ้าระวังการเกิดไฟไหม้ในพื้นที่บ่อขยะโดยใช้โดรนและเทคโนโลยีการรับรู้ระยะไกล
This research was the application of Unmanned Arial Vehicle (drones) in conjunction with remote sensing technology to monitor the occurrence of the waste dump site fire. The research began with designing and developing prototype tools to collect data from the field site. After the tools were tested they were used to measure gases from the dumping sites. After that the field observation was performed in Nonthaburi Province Pathum Thani Province and Pha Nakhon Si Ayuthaya Province. The final step of the research was to collect the data of active fire hot spot and image from MODIS system satellite covered the area of Nonthaburi Province Pathum Thani Province Pha Nakhon Si Ayuthaya Province and Samut Prakan Province in the period of 1 November 2017 to 31 October 2018. The result showed that the developed drone and the prototype gas detection units worked as designed. The result of gases measurement by the tools were similar to the references equipment. The field observation showed that the dumping site mainly composted of plastic organic matter and cotton which up to 74.9 percent in total. This indicated the factor that influenced the dump site gas generation. Based on the combination technique in the research it could be concluded that Drone and Remote sensing technology were the compromised technology for monitoring fire from the municipal solid waste dump site area.

The purpose of this study 1) Study knowledge and attitude towards waste management to generate income: case study of community Phya Prasit Dusit District Bangkok. 2) Comparison knowledge and attitude towards waste management to generate income: case study of community Phya Prasit Dusit District Bangkok classified by gender age occupation education and monthly income. The samples in this research were 154 members. The study participants selected by simple random sampling. The test with 20 items and questionnaires of rating scales with 20 items were used as the research instrument. Percentages means standard deviation t-test for Independent sample F-test and Scheffe’s test and Scheffe’s test analysis were statistical method to analyze data. The results were as follows: 1. Knowledge towards waste management to generate income of community Members Phya Prasit was in high levels while attitude towards waste management to generate income of community members Phya Prasit was in relatively high levels. 2. Comparison of knowledge and attitudes towards waste management to Generate income o community members Phya Prasit Dusit Bangkok. Found that Community members Phya Prasit with different sex age occupation education and income per month were different knowledge towards waste management to generate Incomes. Statistically significant differences at the significance level of 0.05. The attitude towards waste management to generate income it was found that community members Phya Prasit with different sex age education and income per month different attitude towards waste management to generate incomes. Statistically significant differences at the significance level of 0.05.
การพัฒนาผลิตภัณฑ์กระเบื้องยางธรรมชาติต้นทุนต่ำที่มีสมบัติต้านทานการลามไฟ และใช้เศษขยะพลาสติกเอทธิลีนไวนิลอะซิเตทความละเอียดสูงเป็นสารเติมแต่ง
This research aims to develop the natural-rubber floor tiles mixed with high fineness ethylene vinyl acetate plastic wastes (EVA plastics) from the factories. The study use natural-rubber STR 20 at 100 phr with various contents of EVA plastics (e.g. 0 5 10 20 40 and 80 phr) and then mixed with chemical substance at constant ratio include zinc oxide at 5 phr stearic acid at 2 phr mercaptobenzothiazole at 0.5 phr diphenyl guanidine at 0.2 phr and sulfur at 3 phr. The samples are ground by two-roll mill and formed by compression molding at 150 degree Celsius with 30x30x0.2 cm of dimension. The properties of the natural-rubber floor tiles are tested under ASTM standard. From the results it is found that the natural-rubber floor tiles mixed with 10 phr of EVA plastics is the suitable ratio for using as the rubber floor tiles in building. This ratio can increase the hardness tensile strength and wear resistant properties and decrease the density and thermal insulation properties when compare to the natural-rubber floor tiles without EVA plastic.
การใช้เศษพลาสติกโพลิเอทธิลีนเทเรฟทาเลตเป็นวัสดุผสมสำหรับผลิตไม้เทียมขยะกล่องนมที่มีความแข็งแรงสูง
The objectives of this research are to study the production to find the proper ratio to test the properties to suggest the implementation and to transfer the technology of high strength milk carton waste artificial wood mixed with poly ethylene terephthalate (PET) plastic waste. The ratios of this artificial wood included milk carton waste: PET plastic waste equal to 80:20 75:25 70:30 65:35 and 60:40 by weight. The milk carton and PET plastic wastes were grinded though sieve no.4. The artificial woods were casted by hot compression with 180 degree of Celsius for 5 minutes. The samples tested follow the TIS.966-2547 standard. From the results the 60:40 of ratio was the proper ratio which can pass the standard. The increasing of PET waste effected to decrease the density moisture and swelling of properties. In case of bending strength elastic modulus and tensile strength perpendicular to surface the increasing of PET effected to decrease their properties. The developed artificial wood mixed with milk cotton waste and PET plastic waste has the possibility to implement in decoration and construction both interior and exterior wall building. These results can register the petty patent and write the research paper which to transfer the technology.
การคำนวณต้นทุนการจัดการขยะมูลฝอย กรณีศึกษาเทศบาลนครอ้อมน้อย
The purposes of this study were to costs and fees of solid waste management and to provide resolutions towards solid waste management of Omnoi City Municipality. The data were collected by using financial data during 5 years from 2008 to 2012. Then the data were calculated to figure out the costs of solid waste management divided by solid waste management-related cost and non-solid waste management-related cost. The results found that annual solid waste generation rate of Omnoi City Municipality was 0.53 ton/person or 0.65 ton/household. The annual average quantity of solid waste was 27327.26 ton/year and the annual cost of solid waste management was 2084.62 Baht/ton. The costs were separated into the solid waste management-related cost including the cost of main department responsible for solid waste collection service as follows; 1) direct labor 493.79 Baht/ton 2) direct materials 170.83 Baht/ton 3) production cost 231.07 Baht/ton and 4) cost of solid waste management 477.95 Baht/ton. Moreover the non-solid waste management-related cost or the cost allocation supported by other departments consisted of Administration Department and Council 95.78 Baht/ton Office of the Municipal Clerk 308.43 Baht/ton Division of Technical Services and Planning 93.49 Baht/ton Division of Finance 137.25 Baht/ton and Division of Sanitation and Environment 76.03 Baht/ton. Omnoi City Municipality could gather the fees of solid waste management about 152.32 Baht/person/year or 186.61 Baht/household or 290.31 Baht/ton or 13.93 percent of the cost of solid waste management. According to the cost calculation of solid waste management the supporting departments associated with the solid waste management should allocate sufficient budget and provide the cost data which would be useful for administrators at all levels to measure and improve performance. Furthermore additional policies related to the solid waste management should be defined to reduce the management cost and quantity of solid waste. The responsible departments should also promote people’s understanding and realization of duty to pay for fees of solid waste management.
