Resource leveling schedule is important for construction planning process very much because quantity of resource such as labors is limited. The optimal solution to allocate enough resource for every activity is main principle for project successful. But in ordinary they always observe that have different quantity of resource every time periods is called of “Resource fluctuation”. So planners have to adjust first schedule is called of “Resource Leveling”. This method necessary for decrease resource fluctuations or make uniformly resource demand level . However normal method (heuristic method) to solve this problem is difficult and use much time. So in present there is new developed method by create model in spreadsheet computer programs such as Microsoft Excel. This new method can solve very complex resource leveling problem well..So in this research if we add vary relationship options such as SS (Start-To-Start) FF (Finish-To- Finish) or NO (No Relation) for activity in model objective is increasing optimal solution flexibly and output solution is better than El Rayes & Jun ‘s Model. We can discover for optimal solution from this new model that received uniformly resource demand level of project schedule in the end

Mahajanaka mango juice was health benefits and was a source of vitamins especially vitamin A in the form of beta carotene which a potent antioxidant. The purpose of this study was to consumer acceptance and quality of ready to drink mahajanaka mango juice the optimum ratio of mango pulp and water at 1:2 and 1:2.5 to 1:3. Result showed that the optimum ratio of mango pulp to water was 1:2. The mango juice contain of malic tartaric citric succinic and ascorbic acid at 0.005 0.053 0.180 0.005 and 0.138% respectively. The selected juice had 3.49 12.20oBrix 62.25 7.71 59.24 and 5.26 micrograms per gram of pH total soluble solids L * a * b * color values and beta-carotene content respectively. Sensory evaluation result revealed that the selected mango juice was accepted by 30 panelists which was medium like in color appearance odor taste and overall acceptability. Result of consumer test had shown that 97 % of 100 consumers from Lampang province were accepted and 65 % decided to buy the product.

The study of utilizing core pineapple and phufa tea in drinking jelly. The purpose of this study and processing in add fiber from core pineapple wasted and Phufa tea in drinking jelly. The resulfs showed that formulation of carageenan was 10 gram because texture had elastic and softness appropriate. Ratio core pineapple juice : Phufa tea was 60 : 40 percentage had sensibility in color order and flavor for Phufa tea and add fiber from core pineapple was 10 gram because texture had elastic softness and easily suck. The consumer acceptability indicated of target consumer accepted the product. Consumer accepted like very much 41% and interested to buy product 83%. The physical attributes were as follows : L* a* b* value 75.20?0.01 1.31 0.01 28.43 0.02 and respectively Aw = 0.973 0.00 and hardness 5.42 0.45 (N). The chemical analysis of product contained pH = 3.52 0.02 Total soluble solid (TSS) = 15 0.00 (?Brix) and crud fiber content 0.602%. The microorganism (TPC) < 10 cfu/g. and yeast and mold < 10 cfu/g.

The objective of this study was investigate the optimal formulation of Homemade dairy yogurt that 100 percent of dairy milk ratio of dairy milk to skim milk powder and milk powder was 90:10 85:15 and 80:20 respectively as compared to the control (commercial-yogurt Dutch mill). The Yogurt mixeds were heated to 85 C and held for 5 min incubated at 43 C until the pH reached 4.3. The mixes were then stored at 4 C. Yogurt were prepared from higher ratio of dairy milk : skim milk powder and milk powder led to the more time of incubation. The 31 participated sensory evaluation of the sample. From the result choosed first three formulas to analysed in chemical characteristic and bacterial chariacteristic. Total solid of yogurt were prepare from 90:10 and 85:15 of dairy milk : milk powder ratio were not different with control (p>0.05). Total cell count was found to range between 8.08 – 8.50 LogCFU/g and Lactic acid bacteria was found to range between 6.71 – 8.88 LogCFU/g. The optimum formula of homemade dairy yogurt that ratio of dairy milk to milk powder was 90 : 10 and cost per unit (140 g.) was 10.51 Baht compare with control was 14 Baht.

The objective of this research was to compare the effectiveness of water hyacinth and cootail for wastewater treatment by taking water sample from Klong Bangkhen-mai near King Mongkut’s University of Technology North Bangkok. The results showed that there was no diifference on water temperature changes in tanks between two plants. pH of water in coontail tanks was between pH 8.69 to pH 8.91 and pH of water in water hyacinth tanks was slightly increasing between pH 7.71 to pH 8.26. The more amount of coontail added the higher DO would be between 9.18 mg/L to 10.02 mg/L. Moreover COD of water was decreasing according to the amount of cootail addition and more effective than that in water hyacinth tank especially in 150 grams coontail tanks but TS in water hyacinth tanks was much more decreasing than that in coontail tanks. TS was between 21.73 mg/L to 25.91 mg/L. COD was between 45.30 mg/L to 48.34 mg/L.
