This research studied the factors that affect the efficiency of phosphate reduction in the wastewater of the washing process with CaCO3 and CaO produced from eggshell and mussel shell. The study found that the optimum condition for adsorption when using CaCO3 from eggshell is to adjust the pH to be equal to 10 take 15 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing the adsorbent to CaO the optimum condition for phosphate removal is to adjust the pH to 7 take 15 minutes to absorb and add 1 gram of adsorbent which can reduce the phosphate content by 24 percent. The optimum conditions for adsorption when using CaCO3 from mussel shell were to adjust the pH to 10 take 45 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing adsorbents to CaO the optimum condition for phosphate removal is to adjust the pH to 10 take 15 minutes to absorb and add 3 grams of adsorbents which can reduce the phosphate content by 24 percent. In addition when studying the adsorption of impurities in the wastewater such as conductivity turbidity COD and BOD it is found that the optimum reduction conditions can reduce the impurities of the parameters that mentioned above were 19.32 2.60 54.77 and 16.67 percent respectively. CaCO3 and CaO produced from eggshell and mussel shell can be used to absorb impurities in wastewater before releasing into natural water sources.

The objectives of the research on the different egg age affecting the sponge cake were to study the appropriate different egg age to bake the sponge cake and examine the physical and chemical qualities of the sponge cake. The density of the different age cake was measures using the randomized complete block design (RCBD) method at 95% reliability. The quality of senses sight color smell taste and texture and the overall preference were evaluated. The difference of mean was compared with by Duncan New Multiple Rang Test (DMRT) using a computer program to find the appropriate different egg age to bake the sponge cake. 30 testers applied the 5- point hedonic scale to test the product. Research results showed that the testers preferred the egg age at 9 days the most. Ln terms of taste texture and overall preference the mean was 3.70 3.67 and 4.00 respectively. The physical quality test results indicated that the texture of the one-day egg age had the best adhesion and flexibility 0.54 and 0.94 respectively. The egg age at 12 days had the highest lightness (L*) yellowness (b*) and redness (a*) 50.61 4.71 and 23.99 respectively with the statistical significance (p).≤ 0.05

The study of Mucilage Fiber amount from Ocimum Basilicum or Hairy Basil Seed which is used instead of egg in custard cream product in order to study basic formula and production process for custard cream product which made from Mucilage Fiber of Hairy Basil Seed instead of egg. In addition to study end life cycle of Mucilage Fiber in the custard cream. Beginning with appropriate basic formula study and production process of custard cream product found that formula test no.3 got the number 1 ranking which got vote from most of tester. Meanwhile the suitable amount of Mucilage Fiber from Hairy Basil Seed in the custard cream product which there’re 3 level included 10 15 and 20 (gram) so the resulting that almost tester vote 20 gram is best composition of Mucilage Fiber amont. Furthermore we can get smooth and soft custard cream which found when pressing cream on the top bread. After that comparing the basic custard cream from egg found the cream from Mucilage Fiber of Hairy Basil Seed have a total amount of protein and Ash lower than 1.58 and 1.12 respectively basic custard cream from egg and also humidity value more than 1.02 the custard cream which made from egg. The analysis of microbe found that total of microbe which not over standard can maintain 4 days in polypropylene plastic bottle (closed conditon) so 99% of customer feedback and accept “Custard Cream from Mucilage Fiber of Hairy Basil Seed”
