This research aimed to study the design and development to assist in bringing the car seat into the production process and the risk assessment approach to ergonomics to suit operator. Emphasizing the importance of work and trying to create design tools. Organize work appropriately in accordance with the competency and performance of each individual. Using the principles of biomechanics analysis applied in the analysis along with an assessment of the risks by taking into consideration upon 3 factors. 1. The level of severity. 2. The level of frequency.3. Safety measures at the different parts of the body due to which the body must be borne from the outside and in the work. By bringing knowledge of mechanics the proportion of the body anatomy and physiology is able to create the relationship in a model way of Ergonomics which occurs according to the gesture. The use of tools lifting heavy parts and labor pull push and press researchers found in the process of lifting car seat weighs 14.5 kg dimensions width 45 cm length 55 cm and 100 cm in height is the distance of the car seat to shelve. Assembly point distance of 200 cm research has fixed this issue by adjusting the distance of the car seat and shelves by only 50 cm distance can be reduced down to 150 cm and adjust the position of the lifting cushion to reduce twisting torso while assess the biomechanics model of the behavior of all employee in improvement on quality both before and after work station.

The research objective is to utilize the waste water at 12ºC to 20ºC in exchange with the process water at the temperature of 29ºC. After entering the heat exchanger the process water will have the reduced temperature of 19ºC and then will be delivered to the cooler so the temperature of the process water will further be reduced to 15ºC to involve in the production process. Consequently the cooler’s energy use is lower. Since the common coolers used in these days have problems about the clogged system caused by shrimp residue the cleanup of the system is difficult and the maintenance cost is high. With this problem the research and development of the new heat exchanger is carried out resulting to the Shell and Tube Heat Exchanger type with the angled lid and the waste water flow control pads allowing the water alternatingly running through the lower part and upper part of each pad. The process water will flow in the 6 sets of the stainless tubes with 2 mm. thickness ½ inch diameter and 6 meter length. The space between the set is 5 centimeters for exchanging heat with the waste water flowing outside the tubes. The study conclusion is that the new heat exchanger can reduce the temperature of the process water to 19ºC so it can save the electricity cost of the cooler for 886485 baht per year and make the cleanup easier without taking off the equipment parts thus lowering the maintenance cost as well.

Research presents the design and construction of a prototype device alert to clean the solar panels. The measure monitoring of dust and blocking dirt surface of solar panel causes generation Energy low efficiency the devices are alerted to clean solar panel to ensure generation Energy highest efficiency and reduce the cost of solar cell cleaning which will be done 12 times a year. Researchers have introduced electrical and electronic technology with solar panels to provide a reference. Take an installed prototype in process with solar panel energy factory. After that clean the panel referred to the morning every day. This prototype will be processing performance comparison between the solar panels reference with the solar panels factory every day and results via the Internet and record the data in memory. The results of this research found that. Efficiency of electricity production is down 9% as 3 months and 10.47% of the year due to impurities. Dust cover doing have been cleaned twice the efficiency of the electricity production has remained high. This will alert you that washing does not have to be done 12 times as practiced in a solar farm reducing costs 10 times a year.

Water became an important factor for propelling production process of any industries or factories and groundwater was option for production cost reduction especially in areas where had no surfacewater. B.Foods Product International Company Limited an affiliate of Betagro Group was located in Lop Buri Province to daily consume huge quantity of groundwater for production process in its factory. Measuring and recording levels of groundwater in 2 ground tanks related to volume of the water at time point of every 3 hours must continually be done every day in order to prevent lack of water fed into the factory that may impact of its production process. The main problem was caused of unexpected non-working of pumps. Knowing fluctuation of water levels could provide their immediate improvement and recover to avoid serious impacts. A microcontroller board could be employed to control groundwater volume in order that the company could closely follow up levels of groundwater in the ground tanks in real time and continuity. This study went on designing the microcontroller board for managing utility system and maintenance by using with level meter and wireless receiver and transmitter for testing working efficiency every 3 hours of each everyday during 1 February 2016 till 11 March 2016 totally 40 days. It was compared with those of same duration done manually. The findings revealed that the figured from 2 methods became similar and had very close relationship with each other. This could indicate that the simulated microcontroller board could be employed to automatically control groundwater volume efficiently. The company could bring it to appropriately trace levels of groundwater in the tanks in accordance with water usage behavior in each period of time for disruption of production process caused of insufficient quantity of groundwater. And this could be adaptable benefits for improvement of any organizations and also for any further studies

Design and development of solar cells in electric vehicle prototype intended to Design and development of solar cells in electric vehicle prototype Case study electric cars of Rajamangala University of Technology Phra Nakhon. The research process begins with the solar experiment model Solar Thin Film a bent size 19.2 x 9.5 cm technology has applications in Unmanned Aerial Vehicle install to a source of clean electricity generation using 80 Solar Thin Film Cells controlled by Arduino mega size 101.52x 53.3 mm Programming software by Arduino-1.6.9-Windows and Show the result at LCD Solar Monitor Charger from batteries store the electrical energy size 12V/28AH 6 pack for the results showed that such a circuit can charge electricity 5A to 1 hour and to expand the use of rechargeable battery electric prototype instead of using electric vehicle prototype from charging normally Requires 480 Solar Thin Film Cells in trial period hypothesis 6 hour/day. In term of investment evaluation simple payback period is expected to be 4 years. Considering sensitivity analysis it is found that the most sensitive factor is electricity cost cost Solar Thin Film and the cost of Evlink Fast Charge Solution respectively. The results of this study can be used to support decision making in design and development of electric vehicle prototype in the next generation more efficiently
