In Klong Rangsit Pathumthani province where the water entering was filtered by a prototype quality water machine and autonomously controlled by pumps and sensors this research tested improvements to water quality. It employs a total dissolved solid and temperature sensor as part of the consideration of the water quality criterion in accordance with the water quality requirements of the Pollution Control Department and is 99% successful in treating contaminants in water. According to the Pollution Control Departments water quality criteria which are divided into four main categories: very good water quality good water quality degraded water quality and very degraded water quality it is used in the analysis of the division of the four categories of water quality. Machines for producing good quality water to maintain water sanitation during COVID-19 and anticipated flooding across the nation. This is simple to use. Since the made quality water machine prototype has a battery to back up the power for the pump and UV lamp control by filtering water through various stages of a quality water producer prototype it is simple can generate clean water for usage and can be carried. No energy is used and there is no residue filtration effluent. It eliminates 99 percent of water pollutants and has no color.

Develop a prototype of the smart bin for supporting solid waste management at the source. The objective is to develop the functionality of the smart bin to meet the requirements of users. A body design of the smart bin prototype made from plastic with a lid size 25 cm. x 36 cm. x 48 cm. the total volume of the smart bin was 31.5 kg and using ARM STM32F4 series micro controller to control the functions of the smart bin. There is a sensor to measure the temperature and humidity. Ultrasonic level sensor Infrared distance measuring sensor and weight sensor with load cell data display controlling the opening and closing of the smart bin by servo motor. A Smart bin prototype can show the amount of waste. Moreover the level of waste and the weight of the waste inside were showed. The smart bin was showed relative temperature and humidity values inside a bin. The optimum distance to the reflective object of the sensor for opening and closing the smart bin was in the range of 20-50 cm. The Smart bin lid provided approximately 7-9 seconds to maintain the status to lid open representing an average time of 7.4±0.9 seconds. This research will help promote waste management at the source and effectively benefits to solve the problem of waste accumulation in place.

Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature pH electroconductivity total dissolved solids mixed liquor suspended solids and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides this system can be easily applied and also very cost-effective for agricultural practice and frequent maintenance every experimental run was necessary.

This research is to develop a prototype of a salinity intrusion monitoring system using fuzzy logic to extract salinity values. A system is developed according to a fuzzy logic model using FAOs for appropriate agricultural water quality data considering the electrical conductivity (EC) and total dissolved solids (TDS) as indicators of the salinity value by using the Fuzzy Logic Toolbox to produce and test the generated model. Transformation of the generated models to Embedded C format using the Simulink Coder tool installed in the ARM STM32F microcontroller and a 10-fold cross-validation test was used to validate the data extraction. The Root Mean Square Error (RMSE) for the test results was 0.58175 on average. This research result indicates that the generated model is able to extract data that very closely matches the specified data.

The development of lightweight flat sheet prototype from para rubber leaves and para para rubber wood fly ash for field work application can offer an alternative method of adding value to agricultural wastes and help to conserve the environment with green products. The natural fiber especially agricultural waste fiber is an encouraging prospect. Natural fiber composites have been used for building applications. The aim of this research was to investigate the potential use of para wood ash to producing a cement composite as an environmentally material. Material. The cement paste with 5-2 % weight of para wood ash. The specimens were cured at 25± 2 oc for 24 hours. The properties of cement composites mixed with different proportions of para wood ash were compared with Ordinary Portland Cement (OPC). In addition the morphology of para wood ash was examined by using scanning electron microscope. The density increased with the increase in the percentage of para rubber leaves from 1% 2% 4% and 6%. The finding is attributable to the enhanced packing density by the fine para wood ash particles size was found 5-10 um.Moreover para wood ash particles could arrange to fill the inter-particle voids in cement pastes which resulting to increase the compressive strength of cement paste. Consequently para wood ashes could incorporate in the construction materials to enhance the mechanical properties and durability performance of the cement composites
