    This paper gives design and evaluation details of a remote-controlled gas-powered lawn mower to be used in agricultural land. The design makes use of push mechanical power, rotary cutting head, and wireless remote control to enhance the operating efficiency and keep the physical effort involved in hand cutting to a bare minimum. Detailed engineering analysis was conducted to quantify significant performance parameters like power requirement, fuel consumption, and ground coverage. These calculations were confirmed through field tests under real working conditions. Laboratory testing confirmed that the prototype exhibits superior mowing performance, improved driver comfort, and reduced maintenance effort compared to traditional manual operation. In addition to reducing energy consumption, the system significantly simplifies usability and safety through remote control operation and ergonomic handling. The findings confirm the feasibility and prospect of larger application of the prototype in small to medium-sized agricultural enterprises. The system also serves as a foundation for the future development of automation and incorporation of smart farming technology.

    Results revealed that the highest level of food security dimension among rice farming households was 'food accessibility' and 'food availability,' followed by 'food utilization and safety,' and 'food stability', respectively. Regarding food security promotion among rice-farming households, the highest level was 'intra-household understanding related to household food security', followed by 'having a supplementary occupation', 'enhancing social support', and 'self-reliance'. The regression analysis using the stepwise method revealed that off-farm income had a positive effect on household food security, whereas household debt was found to be negatively associated with household food security. Moreover, the structural equation model analysis indicated that intra-household understanding related to food security directly and positively influenced household food security. Furthermore, intra-household understanding related to food security had a positive and indirect effect on household food security through social support in the local community, enhancing supplementary household occupation, and household self-reliance, respectively.
