This research aims to study phytochemicals and potential of Mapok (Parinari anamense Hance) extracts to inhibit germination and growth of Barnyard grass (Echinochloa crus-galli) a common weed in the rice fields. Organic solvents extracted the part of fruits barks and leaves of Mapok included hexane ethyl acetate and methanol. Crude extracts compose of fruit hexane extract fruit ethyl acetate extract fruit methanol extract bark hexane extract bark ethyl acetate extract bark methanol extract leaves hexane extract leaves ethyl acetate extract and leave methanol extract. Crude extracts were tested of phytochemical tested of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition of Barnyard grass. Leaves ethyl acetate extract showed highest inhibit germination and growth of Barnyard grass The leave ethyl acetate extract was separated by column chromatography to yield nine fractions (F1 – F9 fraction) and tested inhibit germination and growth repeating. The results showed that 1. The crude ethyl acetate extracts from the bark of Mapok at a concentration of 3000 ppm showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fraction F8 of leaves ethyl acetate extract showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition.

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 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.

This research aims to study the water hyacinth fiber inside high-density fiber cement board. By using ratio components among cement : fine sand : water hyacinth fiber : water : catalyst accelerated the formations of cement (aluminum sulfate (AI2 (SO4) 3) calcium chloride (CaCl2) sodium silicate (Na2SiO3)) on the ratio 1: 0.2: 0.075: 0.3: 0.03 by weight of total water hyacinth fiber with the steel grating inside. By compressing the mixture cast machine at normal temperature (30 - 35 °C). From the test results the ratio of B4 is the appropriate ratio from the 1st year research result to produce the high-density fiber cement board with the steel grating inside 0.81mm #0.5”. It can pass the TIS 878-2537 standard of Cement Board and good based-on high density and physical properties mechanical properties and thermal insulation. Accelerate the formation of the most suitable cement is calcium chloride (CaCl2).

This research aims to develop the cement board from vesicular basalt fragment which reinforced with steel wire mesh. The ratio of Portland cement type1: fine sand: vesicular basalt fragment: sodium silicate: tap water was equal to 1: 2: 4: 0.03: 0.55 by weight. The 5 sizes of steel wire mesh (steel wire no.25) were installed including: 3/8” 1/2” 5/8” 3/4” and 1”. The cement boards were produced by compression machine. The property tests of cement-bonded fiberboard followed the TIS. 878-1994 standard (cement bonded particle board: high density). From the results the 3/4 of steel wire mesh size was the most suitable size for reinforcing the cement board from vesicular basalt fragment. This developed cement boards was the construction materials which had the high bending strength good thermal insulation and moisture protection properties.
