Introduction

Rice is the main food source for the majority of Indonesian people, playing a vital role in national food security. However, the presence of factories surrounding rice fields raises concerns about heavy metal pollution, particularly lead (Pb). Lead, commonly used in various industries, can contaminate soil and water, and accumulate in rice plants, posing a threat to public health through the consumption of polluted rice. In this context, the remediation of lead polluted rice fields is crucial to maintain the quality of rice and ensure national food security.

The Problem of Lead Pollution in Rice Fields

Lead pollution in rice fields is a significant concern in Indonesia, where rice is the primary food source for the majority of the population. The presence of factories in the Tanjung Morawa-Deli Serdang Industrial Estate has led to the contamination of soil and water with heavy metals, including lead. This pollution can have severe consequences on public health, as lead can be absorbed by rice plants and consumed by humans. The long-term consumption of lead-contaminated rice can lead to various health problems, including neurological damage, developmental issues, and even cancer.

Research on Biochar and Azolla for Lead Remediation

Recent research conducted at McGill University, Canada, has explored the potential of Biochar and Azolla in absorbing lead from polluted soils. Biochar, a type of charcoal produced from burning biomass at high temperatures, has a broad pore structure that allows it to absorb various substances, including heavy metals. Azolla, a type of water fern, also has the ability to absorb heavy metals and can be used as an organic fertilizer. These findings suggest that Biochar and Azolla may be effective in remediating lead polluted soils and reducing the risk of lead contamination in rice.

Analysis of Biomass Sources for Biochar Production

This study analyzed four types of biomass as a source of BioChar: rice straw, rice husk, coconut fibers, and empty palm oil bunches. The results showed that Biochar Husk Rice has the highest potential in absorbing lead. This is because the structure of the pores and functional groups of Biochar rice husks is more optimal in binding lead. The use of Biochar Husk Rice as a remediation technology has the potential to reduce lead levels in the soil and increase rice production that is safe for consumption.

Opportunities for Remediation Technology Development

The findings of this study open up opportunities for the development of remediation technology using Biochar Husk Rice and Azolla. By using Biochar rice husk, it is expected to reduce lead levels in the soil and increase rice production that is safe for consumption. This is crucial to maintain the quality of rice and support national food security. The development of this technology has the potential to create a sustainable solution to overcome the problem of land pollution in Indonesia.

Important Considerations for the Application of Remediation Technology

While the findings of this study are promising, there are several important considerations that need to be taken into account for the application of remediation technology using Biochar Husk Rice and Azolla. These include:

The need for further research: To test the effectiveness of Biochar Husk Rice and Azolla in the long run, and to identify any potential limitations or challenges.
Economic and social aspects: The application of this technology must be considered in terms of its economic and social feasibility, including the cost of production, the availability of biomass sources, and the potential impact on farmers and local communities.
Government support: The role of government in supporting research and development of polluted land remediation technology and education to the community is crucial in ensuring the successful implementation of this technology.

Conclusion

The remediation of lead polluted rice fields is a critical issue in Indonesia, where rice is the primary food source for the majority of the population. The findings of this study suggest that Biochar Husk Rice and Azolla may be effective in remediating lead polluted soils and reducing the risk of lead contamination in rice. However, further research is needed to test the effectiveness of this technology in the long run, and to identify any potential limitations or challenges. The application of this technology must also be considered in terms of its economic and social feasibility, and the role of government in supporting research and development of polluted land remediation technology and education to the community is crucial in ensuring the successful implementation of this technology.

Government support: Encourage government support for research and development of polluted land remediation technology and education to the community, to ensure the successful implementation of this technology.

Future Directions

The findings of this study have significant implications for the development of remediation technology using Biochar Husk Rice and Azolla. Future research should focus on:

Scaling up the technology: Scaling up the production of Biochar Husk Rice and Azolla to meet the demands of large-scale rice production.
