This research objective is to improve the overall equipment effectiveness of the water filtration systems in the case study of the Water Treatment Plant which divides the water production into 4 production lines. The water filtration system has an electric actuator and gear is the main machine in the water filtration system. An electric actuator and gear have more machine breakdowns. That makes the water filtration system is the bottleneck of the water production process. This research study is divided into two steps: the first step is the presentation of the equation and the steps to measure the Overall Equipment Effectiveness of the water filtration system. The equation used data from the computer maintenance management system to analysis on mean time between failure data (MTBF) mean time to repair data (MTTR) and water production process data. The results can be improved the overall equipment effectiveness of the water filtration system increased to 0.11% 0.68% 0.44% and 2.44% respectively in each production process line. And increased Quantity of Filtration Water increased to 328500 m3/year 1168000 m3/year 1022000 m3/year and 3832500 m3/year respectively in each production process line. In this research used the pillar of focus improvement. By adding a protection system to prevent machine breakdown because of the most of the problems are found that the protection system malfunctions. This is the most problem in the 4th And then used engineering knowledge to improve water production and the success factor are required a human resources of all parties to cooperate brainstorm and analyze the causes of various losses in order to eliminate them.

This research presents the processing of fresh guava into guava juice product. to be kept for consumption and distribution in the local area It is an alternative career path that helps rural farmers earn more. and create additional careers for the family But farmers still lack the correct technology tools and processing methods in each production process. Therefore there was a problem of insufficient cleanliness taking a lot of time resulting in unacceptable quality and the production is low the postharvest engineering research group has conducted research to find suitable guava juicer. This study is based on working principles of food processing equipment in general use. Come as a guideline to develop improve and create prototypes. The original guava juicer was a grater roller squeezer. There is a guava-sized subsystem consisting of a sub-chamber with grated rollers and the waste water barrier system consists of a juice sieve chamber a waste separation room a spiral conveyer and a sweeper set. various parts that come in contact with the guava juice is made of stainless steel The power source uses a 1-horsepower electric motor a single-phase electrical system a voltage of 220 volts. The machine has the ability to block water at a rate of 250 kg / hour. The juice obtained must be filtered out again with a centrifugal bag filter capable of filtering water at a rate of 50 liters/hour. The prototype guava juice machine costs 40000 baht and the centrifugal filter bag costs 5000 baht. With just one such machine each of these machines can produce 28000 liters of guava juice/year (112000 bottles a year) able to get a return in 0.08 years with an average processing cost of 4.48 baht/bottle which is appropriate in engineering economics. In investment use a ready-to-drink guava juice machine. Fresh guava ingredients are available throughout the year and have 200 business days/year.

The purpose of the research is to devise and implement for testing the ability to absorb energy from vibration. The results are obtained from simulating the operating status of small machines. In order to get the mechanical force from the vibrating of the machine by using piezoelectric materials (PZT) It was found that the size of the piezoelectric materials used in each condition affected the energy absorption. There are variables interested in different diameters at 27 and 35 millimeters. The result shows that the dielectric displacement is directly proportional to the force used but is inversely proportional to the size of the cross-sectional area of the piezoelectric material. In addition the ability to absorb energy in one second is 4.51 volts and has a maximum energy of 7.4 x10 -8joules.

This continued 2nd year researchaims to study the development of the para rubber press machine with wrought pattern for continued 2nd-year. Used natural para rubber mixed in a Ta-kuong by normally practical para rubber farmer style to evaluate the rubber press machine. A machine consists of the 11 roller sets in vertical pathway with press sticks on top. The components are as follows: a water press roller with a slope surface to reduce the diameter around 1-1.5 mm from a center the 3-pair sets of normal press rollers and the 2 duo sets of wrought pattern rubber press rollers with the induction motor at 1430 rpm. The rotating transmission based on belts and chains with a . The evaluated results produced the dried para rubber sheets thickness at 3.79 mm on average as the 2nd rubber sheet type standardin marketing need. From a top tray a farmer can put a sticky para rubber piece to a roller press machine easier than normal just 5.9 second on average with lower hand power to handler of the rubber pieces. In finally the wrought patternrubber sheets by a worker to carry the ta-kuong to a top tray of a rubber press machine and a rubber press man to put the para rubber pieces to a machine thus the completed 186 wrought rubber sheets per hour on average.
