การใช้ผงอัลมอนด์ทดแทนแป้งสาลีในผลิตภัณฑ์เค้กกล้วยหอมเพื่อสุขภาพ
The objective of this reaearch was to study the appropriarate amount of almond powder instead of wheat flour in 4 different potions: 40 60 80 and 100 % of all wheat flour. And the calculation was done on randomize complete bock design the banana cake for health product nutrition different potion. The calculation was then done by conducting experiments on the characteristic of samples at different in the aspects of color smell taste and the overall liking. There were 40 people that the experiment was conducted by tasting with 5 liking levels (5-point Hedonic Scale). The product acceptance of consumers was then studied on 40 tasters by using the developed questionnaire on consumers’ satisfaction toward the banana cake for health product From the study results it was found that almond powder replacing the wheat flour in the product at 100% was the highest consumer acceptance in the aspect of appenrance color smell taste touch. and the overall liking. From the studies conducted on nutrition it was also found that the banana cake for health net weight 1 pieces has the totle 68.14 calories 5.50 gram of fat protein at 2.60 gram 4.71 gram carbohydrates. Additionally the consumers accepted the 100% almond powder instead of wheat flour
การปรับปรุงสมบัติทางกลของพอลิแลกติกแอซิดด้วยเส้นใยปาล์มน้ำมัน
This research work was to study the improvement of toughness of polylactic acid (PLA) and the cost reduction of raw material with addition of untreated and treated oil palm fiber (OPF). The detail of this work was divided into two parts. The first was to find the suitable condition for surface treatment of OPF with sodium hydroxide (NaOH). The second part was to study the effect of untreated and treated OPF contents on the mechanical properties of PLA. For surface treatment of OPF NaOH concentrations and immersion times were varied from 0 to 15 wt% and 0 to 30 min respectively. Aspect ratio (L/D) and surface of untreated and treated OPF were investigated by using optical microscope and scanning electron microscope (SEM) respectively. The result suggested that the most suitable condition for surface treatment of OPF was NaOH concentration of 10 wt% at immersion time of 20 min. Treated OPF was occurred microporous and had more rough as compare to untreated fiber. For the effect of untreated and treated OPF contents on the mechanical properties of PLA it was evaluated by tensile and impact testing. SEM was used for investigation of interfacial adhesion and fiber dispersion. The results showed that tensile modulus and impact strength tend to increase with adding 2.5 wt% OPF content and slightly changed at higher OPF content whereas ultimate tensile strength and elongation at break decreased with increasing fiber content. Surface treatment with NaOH led to enhancement of mechanical properties of composite due to improve interfacial adhesion and fiber dispersion.

The objective of this project Photocopying Document Management System managed photocopying requirements of employees in Faculty of science. This system can used to track and manage photocopying tasks and store photocopying requirements. Moreover the system can summarize total number of paper usage and calculate statistic of user’s satisfaction. The Photocopy Document Management System is a web application which is developed by using PHP and MySQL. The overall of Photocopying Document Management System user’s satisfaction is at the greatest level which is the total average at 4.79 and the standard deviation at 0.12. the system can perform all of expectations.

This project aim to develop mobile application of activity notification and queue management. The aim of this project is to alert the patient’s activities via mobile devices. Caregiver can create activities to the patient’s mobile device. Also booking a queue in advance via mobile device before seeing doctors. There are no need to book a queue at the hospital. The patients’ medical records are collected via mobile devices which will reduce the time to collect data and data loss problems. The results of performance evaluations on mobile application of activity notification and queue management showed the overall average satisfaction score was 4.63 with a very satisfied level. It can be concluded that mobile application of activity notification and queue management can be used effectively.
การสังเคราะห์ซิลิกาจากขี้เถาแกลบเพื่อมาประยุกต์ใช้ในการทำแก้วคริสตัลสี
The aim of this work was to synthesis the glass crystals by using silica from rice husk ash (RHA) as a raw material. First rice husk was synthesis by heated at various temperatures between 1000-1200 °C and then silica which was heated at the first step was used to be the raw materials for glass crystal. From the result shows that RHA with heated at 1000-1200 °C could be use for silica to synthesis crystals glass. X-ray Diffraction pattern demonstrated that all of condition to heat RHA showed the same results Cristoballite Tridamite are the phase formation appeared all of materials. The crystal glass show blue colour. The optimum condition with show the highest density and density value were obtain with the sample of heated RHA at 1000 °C
