This research had a main purpose for studying the utilization of water hyacinth as the key component of paper production mixed with the agricultural waste as pineapple leaves and leaf sheath of banana tree. The paper pulps were prepared from 5 g/l NaOH at 90-95oC for 3 hours then bleaching with 5 g/l Hydrogen peroxide at 90-95oC for 30 minutes. The whole pulps were detached improvement with 5g/l Acramine 3187 before paper establishment production. Finally the strength of obtaining papers was consideration and competition to any craft paper type. As the results the appropriate ratio of paper was 70% water hyacinth (stem) 10% pineapple leaves and 20% leaf sheath of banana tree. It had 31.19 kN/m2 for bursting strength tearing strength as 309.17 mN and 0.49 mm thickness. The basis weight was 183±5 g/m2. The achieved paper was equivalent as KI craft paper. It was presented for packaging boxes and other procedures.

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.

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.

This research was developed from the old version of the banana slicing machine for slices a banana in sheet-form longitudinal axis only by designed constructed and tested a new version of the banana slicing machine for slices a banana in sheet-form longitudinal and horizontal axis in flat-shape and curly-shape and adjustable sheet-thickness at between 1-2 mm. The new version of the machine would consist of a pressure plate over the feeding channel. The feeding channel could support for 5 fruits of a banana in the longitudinal laying and support for 10 fruits in the horizontal laying. The blade was installed on a drum and the tray was inserted under the drum for finished products. Electric gear-motor was used to drive the drum. The overall dimensions of the machine ware 0.56m (width) 0.64m (Length) 1.38m (High). The experimental was sliced by the machine at 1.5 mm thick in flat-shape and curly-shape can be summarized; the average rate of slide was 167 kg/hr. The average tolerances of sliced was ±0.02 mm the average deviations percentage of sliced was ±1.05 and the average power consumption of the machine was 0.23 kWh. The machines were used by targeted communities with production costs of about 4.78 million baht/year will lead a net profit to 5.97 million baht/year and the payback period of about 0.82 years.
