This research is the study of microwave distribution in the drying chamber to develop the belt-conveyor microwave dryer. The dimensions of the drying chamber are 90 cm width 3 cm length and 30 cm height. Two 800 W magnetrons were installed at the top of the chamber. It was found that the uniform of microwave distribution was observed at the center area of drying chamber. The uniform microwave distribution in the drying chamber at 400 W is achieved. A microwave leakage from the prototype is within the microwave oven safety standard of the US Department of Health and Human Services. This study can be used as a guideline for an industrial design for belt-conveyor microwave dryer.

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.
