การประเมินประสิทธิภาพเครื่องอัดลูกอมขิง
This research objective was to design the ginger candy compression machine and determine the efficiency and capacity for saving time and labor in pressing ginger candy for community enterprise groups Pim Malaherb Chiang Rai Province. Ginger candy compression machine consists of the main structure namely the extruder and power transmission systems. The machine was designed with two horsepower motors or 1.5 kilowatts to drive the shaft and to rotate the screw through the flange. This study installs the inverter to control the motor speed at 1000±10 1200±10 and 1400±10 rpm. The extrusion die had an average diameter of 9.7 millimeters. The results found that the motors speed that was suitable for compression was a Rotational speed of 1400±10 rpm. When the speed increased the efficiency and the working rate increased too. The amount of ginger stirred was used at 300 500 600 900 1000 1500 2000 and 3000 grams. The maximum efficiency was 90.85 percent. The efficiency increased with the amount of ginger stirred. The ginger candy compression machines engineering economic analysis results found that the machines operating cost was 18063.6 baht per year. When considering the machines operation at 792 hours per year the payback period was 6 months and 11 days.
การทำงานเป็นทีมที่ส่งผลต่อประสิทธิภาพการทำงานของคุณครูและบุคลากรทางการศึกษาในสังกัด โรงเรียนสำนักงานเขตพื้น ที่การศึกษาประถมศึกษากรุงเทพมหานคร
This independent study to the teamwork performance that affects the efficiency of government teachers and education personnel affiliated with the schools under the office of the primary education in Bangkok area. The objectives are 1) to study personal factors of education personnel that affect teamwork performance that affect the efficiency of government teachers and education personnel affiliated with schools under the office of the primary education in Bangkok area. Furthermore 2) to study the team composition that affects the work performance of teachers and education personnel affiliated to schools under the office of the primary education in Bangkok area. By using questionnaires designed to teachers and education personnel from the office of the primary education in Bangkok area for 334 samplings using the Taro Yamanae formula. Testing was done in descriptive statistics using frequency percentage mean and standard deviation while hypothesis testing was t-test F-test (ANOVA) and double test by method Least Significant Difference (LSD) and Pearson Product Moment Correlation Coefficient. The result of the study found that most responders were female aged between 21-30 years old working in middle-sized schools and having a bachelors degree. Most had an income between 15001-20000 Baht and most of them had been government teachers in operating positions for 5-10 years as civil servant and the study found team composition factors such as environment composition and appearance the feature design and process affected the teams performance at a high level. The reason was trust between education personnel team members. There also was a high degree of satisfaction with the working environment and the excellent collaboration between team members. Team members were able to resolve obstacles together effectively. There was good communication between members and the members had no conflict with each other’s. However the education personnel should have a positive attitude to work with other people and alone. Negative thinking cause no bias towards others and decrease performance. The results of the hypothesis testing indicated that sex age school size income position level different occupations of government teachers and education personnel could not differently affect teamwork performance as could not different for education job titles and working ages the difference will affect performance of the team composition factors. The factors were statistically significant at the 0.05 level and the team composition factor. There also was a correlation in the same direction with the efficiency of teamwork of government teachers and education personnel. It was statistically significant at the 0.05 level.

การศึกษาการบำบัดน้ำเสียจากการย้อมผ้าแบบเคลื่อนที่โดยใช้ถ่านกัมมันต์จากกะลามะพร้าว
The dyeing industry both of business size and household size where the remaining water from the dyeing process is dumped into pipes and flows into natural water sources causing sewage problems. Therefore a column type wastewater treatment system has been developed by using a filtration system along with an adsorption system. The materials used to treat the wastewater from dyeing are gravel sand charcoal from wood and activated carbon from coconut shell. The study was conducted on the synthesis activated carbon from coconut shell using for color and molecules adsorption. The amount of activated carbon from coconut shell was varied at 200 400 600 and 800 g applying with filter media and other adsorption materials taking 1 hour to treat the wastewater from dyeing. The parameter using to measure water quality consisted of color value pH suspended solids conductivity turbidity value COD and TKN to indicate the water quality before and after treatment evaluating the efficiency of the wastewater treatment system. The best ratio that can treat the color is the formula containing 800 g of coconut shell activated carbon. It was able to treat the color equal to 5.94 SU or 99.43 percent compared to the wastewater before treatment.
