Objectives of this research are to study 1) method of cooking preserved substandard bananas 2) proper amount of preserved bananas in banana custard cake 3) acceptance of banana custard cake 4) length of time banana custard cake could be kept in refrigerated temperature. This study used (p0.05) statistically difference. When substandard bananas were cooked for 15 30 and 45 minutes evaluators accepted the preserved bananas cooked for 45 minutes with the best all around score. In studying the proper amount of preserved bananas in banana custard 0 : 100 50 : 50 80 : 20 and 100 : 0 ratios of banana to palm sugar ; it was found that evaluators accepted as statistically different the ratio of 80 : 20 preserved bananas to palm sugar. In studying acceptance of banana custard cake the ratio of sponge cake to banana custard 15 : 15 grams 10 : 20 grams and 5 : 25 grams ; it was found that evaluators accepted as statistically different the ratio of sponge cake to banana custard 10 : 20 grams with the best all around score. In studying the length of time the banana custard cake could be kept in refrigerated temperature at 5±2 degrees Celsius for 3 weeks. The yeast and mold counts were 219 (CFU/g). Therefore the banana custard cake could be kept 2 weeks in a refrigerator.

A Comparison Efficiency of Cafeteria Wastewater Treatment with EM Produced by Banana Watermelon and Guava Case Study : Rajamangala University of Technology Phra Nakhon Cafeteria ( North Bangkok Campus) has the objective to compare the efficiency of wastewater treatment by using the EM microbe for the Cafeteria that has no waste water treatment system. The treatment solution was leavening agent EM : Molasses : Fruits : Water in the ratio 1 : 1 : 2 : 20 liters (as an experimental group) and leavening agent EM : Molasses : Water in the ratio 1 : 2 : 20 liters (as a control group). respectively and mixed each solution set in wastewater treatment ratio of 1 : 1000 (EM 1 part : wastewater 1000 part) . In the experiment use the 10 liters of wastewater sampling and added the EM microbe solution every 3 days 10 ml per a day and daily for 3 weeks. Collecting the wastewater every 7 day. Parameters in this experiment are BOD COD SS Oil and Grease pH Color and Odor. The comparison showed that the EM made from watermelon can reduce the BOD and SS of wastewater is the best. And adapt the most of pH to pH 7. The EM make from guava can reduce the COD Oil and Grease is the best. The results were in the standards of sewage release of the building type B. In the 1st 2nd and 3rd week the BOD COD SS Oil and Grease and pH from the waste water treatment with EM microbe that make from Banana Watermelon and Guava ( as a Experimental group) and molasses (as a Control group) only are statistically different at the .05 level. By the way the Color and Odor of the waste water analysis before and after treatment with EM microbe 4 species still have yellow color and bad smell.

Natural compost or organic fertilizers suitably applied to soil since it improves soil quality is cheap and easy to manage and has no pollution residues. However the right ratio of ingredienttypes as well as enough fermentation period have to be tested in order to obtain suitable fertilizer for each particular plant species. In this study researchers have conducted experimental fermentation of organic composts composed of various ratios of either residues of bagasse or banana pulp mixed with sludge. This organic compost performs as organic fertilizer adding nutrients to the sludge since the sewage sludge by itself can only help improve soil structure but has insufficient nutrients for the growth of plants. The sludge in the experiment was obtained from sewage sludge at WatSuanKaew Nonthaburi province. The results of the organic compost after fermented 49 days showed that the compost turned to brown and black and most plant materials were already macerated. The compost of sewage sludge mixed with banana pulp in the ratio of both 0.75 to 5.0 and 1.0 9 to 5.0 yielded the best growth of the morning glory. Both formulas accelerated the growth of seedlings of the plant to a high average of 15.0 ± 0.3 cm after grown for14 days. The concentration of main nutrients was also close to the values specified by the standard compost. This banana pulp compost with pH 7-9 helpedreduce the acidity in the soil. While organic fertilizer derived from sewage sludge mixed with bagasse could only help accelerate the growth of the seedlings but did not accelerate the proliferation of immature plants. Additionally the ratios of carbon to nitrogen in all bagasse composting samples were more inflated whereas the nitrogen phosphorus and potassium were under the specified standard. This bagasse caused lower pH to 5.0-6.0 contributing more acidic to soil. From all results of these findings the organic compost from the fermentation of banana leafs was therefore appropriated for improving soil quality by mixing with sludge. The organic compost provided enough major and minor nutrients that stimulated the plant growth as well. However the formulated ratio of the bananas leafs and sludge mixtures needed to be prior experimentally tested.

This research was aimed to 1) To development of reused oasis clay formula suitable for banana leaf products 2) To study the optimum heating time in microwave oven 3) The reused oasis clay of the best tested was used for creating banana leaf product and 4) survey the experts’ satisfaction of the reused oasis clay and the consumers’ satisfaction of the product In this study 5 reused oasis clay formulas were developed. From these one were selected and heat of clay in microwave at time 3 8 13 and 18 seconds. The properties of reused oasis clay were tested by 5 experts. The reused oasis clay of the best tested was used for creating banana leaf product. Then the consumers’ satisfaction of the reused oasis clay for banana leaf products was collected from 120 customers in clay products shop or banana leaf products of Bangkok and suburban area by means of random sampling and the data were statistically analyzed in terms of percentage mean and standard deviation. It was found that the reused oasis clay of the best formula and the optimum heating time in microwave oven was formula at 4 and heating time in microwave oven established were 8 seconds. The properties of reused oasis clay suitable for creating banana leaf product. The experts’ satisfaction of the best reused oasis clay was at ( x = 4.71 S.D. = .169). The consumers’ satisfaction of the reused oasis clay for banana leaf products was at the high level of ( x = 4.20 S.D. = .182).

The objectives of this research are 1) to design pattern by technique of silkscreen on the banana fibers integrated cotton cloth for women’s working dress 2) to design women’s work dress from cotton blended with banana fibers by technique of silkscreen for female workers and 3) to study the satisfaction of female workers for working dress which sewing from the cotton blend with banana fibers for female work uniform by technique of silkscreen. The samples of the study were 399 working females with ages between 21-60 years old in Bangkoks Sathon and Bang Rak district. The research instrument was the questionnaire and 12 prototypes of cotton blend with banana fibers for female work uniform by the technique of silkscreen consist of dress coat and skirt. The questionnaires were randomly distributed. The data was analyzed using statistical percentage mean and standard deviation. The findings indicated that the majority of participants were 21-30 years old with married marital status educated with Bachelor degree working in the position of employees and have the average monthly income of 15000-20000 THB. Most of the participants have never purchased or wore the dresses or attires made from cotton blend with banana fibers. The decisive reasons for purchasing the working uniforms were personal preferences the frequency of purchases was on the monthly basis and the prices of purchased working uniforms were between 500-1000 bath each. The analysis of the satisfaction of participants toward the working females suggested the triangle pattern dresses is at the highest satisfaction rate followed by the circle mixed and square pattern with the means of 4.47 4.42 4.26 and 4.07 respectively. The circle pattern coats is at the highest satisfaction followed by mixed triangle and square pattern with means of 4.314.22 4.21 and 3.87 respectively. The circle pattern skirt is at the highest satisfaction rate followed by the mixed triangle and square pattern with means of 4.18 4.04 4.00 and 3.82 respectively. It was found that every pattern received the high degree of satisfaction.
