Sawah Rice Conservation (Oryza sativa, L) with an Integrated Plant Management System (PTT) in Aman Damai Village, Kuala District, Langkat Regency

Introduction

The management of lowland rice plants using the Integrated Plant Management System (PTT) is an essential solution to increase productivity and maintain the balance of the agricultural ecosystem in the Village of Aman Damai, Kuala District, Langkat Regency. PTT integrates modern agricultural technology with the traditional practice of farmers, resulting in more sustainable and profitable cultivation techniques. This study aims to analyze several important aspects in the comparison of the use of PTT systems and non-PTT systems on rice land.

Research Purposes

This research has five main focus:

Analyzing the Difference in Pesticide Use: To compare the use of pesticides between PTT and Non-PTT systems.
Analyzing Fertilizer Use: To compare the use of fertilizers in both systems.
Evaluating Productivity and Income: To analyze the differences in productivity and income of farmers using PTT and Non-PTT systems.
Assessing Soil Macrofauna Diversity: To analyze the diversity of soil macrofauna in both systems.
Examining Soil Nutrient Content: To compare the difference in the nutrient content of soil between the two systems.

Research Methods

The research was conducted from April to June 2008, using several analytical methods. For the use of pesticides and fertilizers, as well as productivity and income, researchers used an average different test (T-test). To analyze land quality, researchers used the Simpson diversity index identified at USU FMIPA. Meanwhile, for testing soil nutrient, it was carried out at the USU Faculty of Agriculture Research and Technology Laboratory.

Research Results

1. The Use of Pesticides

The results show that the use of pesticides between land and PTT and non-PTT systems does not show significant differences. The only difference lies in the dose used by farmers. This indicates that the use of pesticides is not a major factor in the comparison of PTT and Non-PTT systems.

2. The Use of Fertilizer

There is a significant difference in the use of organic fertilizer. Farmers who implement the PTT system are more likely to use manure and rice straw, while farmers in the non-PTT system do not implement this practice. This suggests that the PTT system promotes the use of organic fertilizers, which can lead to more sustainable and environmentally friendly agricultural practices.

3. Productivity and Income

Farmers who use the PTT system show higher productivity and income compared to farmers who use non-PTT systems. This indicates that PTT is more efficient in increasing agricultural output. The results also suggest that the PTT system can lead to increased economic benefits for farmers.

4. Macrofauna Diversity of Soil

Based on the calculation of the Shannon-Wiener diversity index, the result is 0.570 for the PTT system and 0.603 for the non-PTT system. Although this value shows diversity, a higher number in the non-PTT system shows that ecosystems may be more stable in terms of insect diversity. This suggests that the PTT system may have a negative impact on soil macrofauna diversity.

5. Soil Fertility

Land that implements a more conserved PTT system, shows long-term benefits for soil fertility. This suggests that the PTT system can lead to improved soil health and fertility.

Conclusion

Overall, the application of the Integrated Plant Management System (PTT) in the Village Aman Damai shows more positive results compared to the non-PTT system. Although the use of pesticides is not significantly different, the use of organic fertilizer and increased productivity and farmers' income is an important indicator of the success of this system. Thus, the application of PTT can be a promising alternative for the management of more sustainable and profitable lowland rice fields. Through this research, it is expected that farmers can better understand the benefits of PTT's approach and adapt to agricultural practices that are more environmentally friendly.

Recommendations

Based on the research findings, the following recommendations are made:

Promote the use of organic fertilizers: Farmers should be encouraged to use organic fertilizers, such as manure and rice straw, to reduce the use of chemical fertilizers.
Implement PTT system: Farmers should be encouraged to implement the PTT system to increase productivity and income.
Monitor soil macrofauna diversity: Farmers should be encouraged to monitor soil macrofauna diversity to ensure that the PTT system does not have a negative impact on soil health.
Conduct further research: Further research should be conducted to evaluate the long-term effects of the PTT system on soil fertility and macrofauna diversity.

Limitations

This study has several limitations, including:

Small sample size: The sample size of this study is small, which may limit the generalizability of the findings.
Limited scope: This study only evaluates the PTT system in one village, which may not be representative of other villages.
Lack of control group: This study does not have a control group, which may limit the ability to compare the PTT system with other agricultural practices.

Future Research Directions

Future research should focus on:

Evaluating the long-term effects of the PTT system: Further research should be conducted to evaluate the long-term effects of the PTT system on soil fertility and macrofauna diversity.
Comparing the PTT system with other agricultural practices: Future research should compare the PTT system with other agricultural practices to evaluate its effectiveness and sustainability.
Developing a more comprehensive PTT system: Future research should focus on developing a more comprehensive PTT system that incorporates multiple components, such as crop rotation, cover cropping, and integrated pest management.
