The Optimum Model of Intensive Rice Cultivation: Suppress Methane Emissions and Increase Productivity in Technical Irrigation Rice Fields

Introduction

Intensive rice cultivation has been a topic of interest in recent years due to its potential to increase food production. However, the impact of this practice on the quality of soil, water, and methane gas emissions needs to be considered. This study aims to analyze the changes in the quality of soil, water, and methane emissions due to increasing planting intensity, as well as to compile an optimal intensive rice cultivation model with a low-integrated plant management approach (PTT).

Background

Rice is one of the most widely consumed staple foods in the world, and Indonesia is one of the largest producers of rice. However, the increasing demand for rice has led to the intensification of rice cultivation, which can have negative impacts on the environment. The use of fertilizers and pesticides can pollute soil and water, while the cultivation of rice in flooded fields can lead to the production of methane, a potent greenhouse gas.

Methodology

This research was conducted using a divided plot design, with the main factor under study being the irrigation system, namely the disconnected system and the system flows continuously (inundation). The child's plot factors under study were fertilization, which was carried out based on recommendations for regional regulation No. 40 of 2007 and recommendations for laboratory analysis. Data analysis was carried out with a variety of analysis (ANOVA) and continued with the Duncan Multiple Range Test (DMRT) test. Sustainability analysis using the Multidimensional Scaling (MDS) method with a dynamic model system approach.

Results

The results of this study showed that intensive rice cultivation with increasing planting intensity did not reduce the quality of soil and water. In fact, methane emissions can be reduced up to 66.05% with the application of the optimal model. Intensive rice cultivation with the PTT approach can increase rice production and productivity by up to 30%, as well as significantly increase farmers' income.

The Optimum Model of Intensive Rice Cultivation

The optimum model of intensive rice cultivation produced is to plant rice four times a year with rice-rice-paddy-rice-rice planting patterns using a PTT system, especially with an intermittent irrigation system and fertilizer administration according to plant nutrient needs (recommendations for laboratory analysis results with a dose of 100% added probiotics). This model can significantly reduce methane emissions, from 218,826,889.43 kg CH4 to 397,181.03 kg CH4 in 2030.

Sustainability Analysis

The sustainability index of the optimum model of intensive rice cultivation is in the range of 42.84-66.54, which is included in the sufficient category. Statistical test results show that the Rap-Inlasit-IP 400 method is effective for evaluating the sustainability of the application of the optimum model of intensive rice cultivation in technical irrigation rice fields.

Implications

This study provides concrete evidence that intensive rice cultivation with the PTT approach can be a solution to increase food production without sacrificing environmental quality. The application of this optimum model can be a reference for farmers and the government to improve the efficiency of rice production and encourage the sustainability of the agricultural system in Indonesia.

Suggestions for Future Research

It is necessary to do further research to examine the optimum model of intensive rice cultivation in various agroecological conditions in Indonesia.
The need for an educational and counseling program to farmers regarding the application of the optimum model of intensive rice cultivation.
The government needs to provide incentives and support for farmers who apply the optimum model of intensive rice cultivation.

Conclusion

By applying the optimum model of intensive rice cultivation, it is expected to increase rice production, farmers' income, and maintain environmental sustainability. This will contribute to the realization of food security and sustainable development in Indonesia.

Future Directions

The application of the optimum model of intensive rice cultivation can be a reference for farmers and the government to improve the efficiency of rice production and encourage the sustainability of the agricultural system in Indonesia. However, further research is needed to examine the optimum model of intensive rice cultivation in various agroecological conditions in Indonesia. Additionally, an educational and counseling program to farmers regarding the application of the optimum model of intensive rice cultivation is necessary. The government also needs to provide incentives and support for farmers who apply the optimum model of intensive rice cultivation.

Limitations of the Study

This study has several limitations. Firstly, the study was conducted in a specific region of Indonesia, and the results may not be generalizable to other regions. Secondly, the study only examined the impact of the optimum model of intensive rice cultivation on methane emissions and did not consider other environmental impacts. Finally, the study did not examine the economic viability of the optimum model of intensive rice cultivation.

Recommendations for Future Research

Based on the limitations of this study, several recommendations for future research are made. Firstly, further research is needed to examine the optimum model of intensive rice cultivation in various agroecological conditions in Indonesia. Secondly, the impact of the optimum model of intensive rice cultivation on other environmental parameters, such as soil quality and water quality, should be examined. Finally, the economic viability of the optimum model of intensive rice cultivation should be examined.

Conclusion

In conclusion, this study provides concrete evidence that intensive rice cultivation with the PTT approach can be a solution to increase food production without sacrificing environmental quality. The application of this optimum model can be a reference for farmers and the government to improve the efficiency of rice production and encourage the sustainability of the agricultural system in Indonesia. However, further research is needed to examine the optimum model of intensive rice cultivation in various agroecological conditions in Indonesia.
