The Green Revolution has significantly contributed to agricultural development. However, it has also caused environmental damage due to excessive use of agricultural inputs and land exploitation. To promote sustainability in line with the Sustainable Development Goals (SGDs), organic farming has been recommended to improve and maintain agroecosystems. In Bali Province, Indonesia, the concept of Tri Hita Karana (THK), a form of local wisdom, has guided farmers in implementing the System of Rice Intensification (SRI) technique introduced by the government. This study explored how organic rice farming integrates local wisdom, assessed farmers' knowledge and attitudes towards SRI, and examined government support initiatives for organic rice farming. The results revealed that SRI farming aligns with the principle of nurturing the soil to enhance fertility, improving soil, water, and air in paddy fields and surrounding areas. THK also guides organic farming practices in SRI, helping farmers maintain a harmonious relationship with God, nature, and fellow human beings. Farmers generally have a high level of knowledge about SRI and agree with its implementation. While the government supports organic rice farming through policies and farmer subsidies for production inputs, it is recommended that efforts be intensified through improved agricultural extension programs that implement more demonstration plots based on the concepts of learning by doing and seeing is believing, increased SRI-related training activities for farmers, and more extension workers to enhance outreach across Bali's dispersed agricultural regions.

Weeds in paddy fields can seriously reduce rice yield. An intra-row weeding device with double-layer elastic rods was designed, considering the differences in mechanical properties between rice and weeds, which can press weeds into the soil and avoid damaging rice. The elastic force of the elastic rods can be adjusted by changing the position of the regulating mechanism to adapt to different weeding conditions. A measurement experiment was conducted to determine the variation rule of elastic force. The quadratic orthogonal rotation combination discrete element simulation experiment, which used weeding depth and weeding speed as experimental factors, and the amount of soil disturbance and the force of the inner and outer elastic rod in the horizontal and vertical directions as experimental indicators, was conducted to study the interaction between the weeding device and the soil. The optimal weeding parameters were obtained: the weeding depth was 15 mm, the weeding speed was 0.9 m/s. The field experiment, which used the various parameters of the weeding device as experimental factors and the weeding rate and damaging seedling rate as experimental indicators, was conducted to determine the weeding effect. The experimental results showed that the optimal position of the regulating mechanism was 270 mm, with a weeding rate of 80.65% and a damaging seedling rate of 3.36%. The weeding rate can be increased by at least 11.18% by adjusting the regulating mechanism to a suitable position under the same weeding conditions. This study can provide a reference for research on weeding machinery for organic rice.
