การใช้ประโยชน์จากกระเบื้องเหลือทิ้งสำหรับผลิตภัณฑ์อิฐบล็อกประสานน้ำหนักเบาเพื่อส่งเสริมวิสาหกิจชุมชน

The purpose of this study were to conduct and to evaluate the effectiveness of Automotive service technician The research procedure starting by collect and study document : research paper international occupational standard (Oklahoma Department of Career and Technology Education) and competency needed in Motorcycle Mechanic suggested by 7 person who working in this field. All data will be referred for behavior objectives list and learning materials design such as information sheet practice operation sheet for experience skill training evaluation sheet with evaluation criteria which clearly listed topics. The sample group in this study was 19 PAJAMANGALA UNIVERSITY OF TECHNOLOGY PHRANAKHON Faculty of Industrial Education in academic year 2 0 1 7 . Pre-test will be given before training steps according to the manual. The students will do the test after each training topic. At the training end Post-test will be given and student final assignment will be evaluated by 5 experts. The Pre-test and Post-test scores will be statistical mean difference test. The research results found that the student final assignment competencies evaluation in percentage mean score was 87.55/94.66/85.13 that higher than 80/80/80 about the expectation. The test percentage mean score after training each topic was 92.11 that higher than 90 about the expectation. The percentage mean score difference test between before and after training was significant at statistical level .01 and the after training score was higher than before training score.

The objectives of this research are to study the production step proper ratio physical properties mechanical properties and thermal insulation of concrete blocks mixed with waste ceramic powder. The ratios of concrete block mixed with waste ceramic powder include Portland cement type1: quarry dust: waste ceramic powder equal to1: 6.8: 0.2 1: 6.7: 0.3 1: 6.6: 0.4 1: 6.5: 0.5 and1: 6.4: 0.6 by weight. Water per cement ratio are 0.6 by weight. The concrete block samples were castedby the general production as same as the ordinary concrete blocks and were tested follow TIS.58. From the results the best amount of waste ceramic powder which put into concrete block is 1: 6.7: 0.3 of ratio. The proper ratios of waste ceramic powder can decrease the density or weight and increase the thermal insulation efficiency of concrete blocks. However the high amounts of waste ceramic powder effect to decrease the mechanical properties concrete blocks that are lower than TIS.58 standard.

This research aims to develop the coconut coir ceiling board mixed with natural latex. The 6 ratios of gypsum plaster: coconut coir: sodium silicate: natural rubber: tap water are equal to 1: 0.15: 0.03: 0.00: 1 1: 0.15: 0.03: 0.01: 1 1: 0.15: 0.03: 0.02: 1 1: 0.15: 0.03: 0.03: 1 1: 0.15: 0.03: 0.04: 1 and 1: 0.15: 0.03: 0.05: 1 by weight. The ceiling boards were produced by casting in normal temperature (30 – 35 degree of Celsius). The properties testing of coconut coir ceiling board mixed with natural latex followed the TIS 219-2009 standard (gypsum plasterboard) including: breaking load nail pull resistance deflection water absorption density thermal conductivity coefficient and real usage. From the results 1: 0.15: 0.03: 0.03: 1 ratio is the most suitable ratio of coconut coir ceiling board mixed with natural latex. This developed ceiling boards can reduce the quantity of coconut coir waste and get the good thermal insulation ceiling board products.

The purposes of this research were to developed the tea Product from Ya Nang Melientha suavis and safflower. The objective was to study the optimum drying conditions of Ya Nang tea leaf and Melientha suavis 2) to study the optimum ratio between Ya Nang tea leaf and Melientha suavis and Safflower in the tea formulation and 3) to study the acceptance of Ya Nang tea products with Melientha suavis and safflower flowers from consumers It was found that the suitable drying time of tea leafe was 4 h at 60o c with moisture content lower than 10% that was in agreement with standard. The proper ratios between Ya Nang Melientha suavis and Safflower such as 100:0:0 60:20:20 60:30:10 and 60:10:30 were evaluated the sensory properties by 30 panelists. It was found that the highest acceptability sure was found in formulation 3. In addition the DPPH radial scavenging activity and phenolic content were 66.51 μM Trolox/ml and 14.46 mg GAE/ml respectively for the accepted tea formulation. For the consumer test (120 consumer) the data relating to product interest acceptability and antioxidant properties were 59.20% 96.70% and 75% respectively. This results indicated that tea Ya Nang Melientha suavis and Safflower is accepted by consumer.

The objective of this research is to develop the concrete flooring tile product from old asphalt road waste. The 6 ratios of Portland cement type1: coarse sand: old asphalt road waste: water reducer type A: tap water were designed including: 1: 5: 0: 0.02: 0.4 1: 4.5: 0.5: 0.02: 0.4 1: 4: 1: 0.02: 0.4 1: 3.5: 1.5: 0.02: 0.4 1: 3: 2: 0.02: 0.4 and 1: 2.5: 2.5: 0.02: 0.4 by weight. The concrete flooring tile casted with the compressive machine. The property tests followed the TIS.378 - 1988 (concrete flooring tiles). According to the result it was found that the 1: 2.5: 2.5: 0.02: 0.4 was the proper ratio of the concrete flooring tile. The increasing of old asphalt road waste in concrete flooring tile effected to decrease the water absorption and thermal conductivity properties. In term of the density and bending strength properties there were not many differences. The developed concrete flooring tile product from old asphalt road waste can use as same as the common concrete flooring tile product in market.
