Distribution of Early Maps of White Root Mushroom Diseases (JAP) on People's Rubber Plantation in Asahan Regency

Introduction

The White Root Fungus Disease (JAP), caused by Rigidoporus Microporus, is a serious threat to rubber plants, particularly in small plantations in Indonesia. This disease has been reported in various regions, including Asahan Regency, where it poses a significant risk to the livelihoods of rubber farmers. In this study, we aimed to investigate the distribution of early maps of White Root Mushroom Diseases (JAP) on people's rubber plantations in Asahan Regency.

Background

Rubber plantations are a significant contributor to the economy of Asahan Regency, providing employment opportunities and income for thousands of people. However, the spread of JAP has been a major concern, as it can lead to significant losses in productivity and revenue. The disease is caused by a fungus that infects the roots of rubber trees, leading to a range of symptoms, including yellowing of leaves, stunted growth, and eventually, the death of the tree.

Methodology

This study was conducted in five people's rubber plantations in Asahan Regency, including plantations in Aek Teluk Kiri Village, Teluk Dalam District; Kampung Baru Village, Simpang Empat District; Silomlom Village, Simpang Empat District; Pulo Pale Village, Air Batu District; and Sei Alim Ulu Village, Air Batu District. The study involved plant pathology laboratories at the Faculty of Agriculture, University of North Sumatra, with a height of about 25 meters above sea level. The method used in this study was a survey with random sampling. The data obtained were analyzed using correlation analysis and mapping using a geographic information system (GIS).

Results

The results of the study showed that the highest disease attack was detected in Sei Alim Ulu Village with coordinates 2 ° 83,167'54.5 "LU and 99 ° 61.997'34.7" BT, with a severity of 41.66%. Conversely, the lowest attack was found in Silomlom Village at coordinates 2 ° 87'06 " - 2 ° 87'23" LU and 99 ° 70'09 " - 99 ° 70'65" BT, where the severity is only 5%.

Analysis of the Spread of Disease

The spread of this clock disease can be influenced by various factors, including environmental conditions, planting patterns, and plant management in each location. Height, humidity, and soil type are environmental factors that can contribute to the severity of the disease. In Sei Alim Ulu Village, conditions that support mushroom growth may be higher than Silomlom Village, which may have better plant management or soil conditions that do not support mushroom growth.

The Use of GIS in Disease Mapping

The use of GIS in this study allows a map of the distribution of diseases to be presented clearly, making it easier for farmers and related parties to make decisions. This mapping not only helps in understanding the location and intensity of the attack, but also in formulating a more effective disease control strategy. With the right information, farmers can intervene early, such as the application of fungicides or the application of better aquaculture practices to reduce the impact of this disease.

Conclusion and Recommendations

From the results of the study, it is clear that periodic monitoring and the use of mapping technology such as GIS is very important for the management of rubber plant diseases. Collaborative efforts are needed between farmers, academics, and the government to overcome the spread of jap disease. It is hoped that further research is conducted to explore more deeply about the factors that influence the spread of disease and the development of environmentally friendly control methods.

Future Directions

Through this approach, it is hoped that the sustainability of people's rubber plantations in Asahan Regency can be maintained, while increasing the productivity and welfare of rubber farmers. Further research is needed to explore the potential of using GIS and other mapping technologies to monitor and manage rubber plant diseases. Additionally, the development of environmentally friendly control methods is essential to reduce the impact of JAP on rubber plantations.

Limitations of the Study

This study has several limitations, including the small sample size and the limited scope of the study. Future studies should aim to include a larger sample size and a more comprehensive scope to provide a more accurate understanding of the distribution of JAP in Asahan Regency.

Conclusion

In conclusion, this study highlights the importance of periodic monitoring and the use of mapping technology such as GIS in the management of rubber plant diseases. The results of the study show that the highest disease attack was detected in Sei Alim Ulu Village, while the lowest attack was found in Silomlom Village. The use of GIS in this study allows a map of the distribution of diseases to be presented clearly, making it easier for farmers and related parties to make decisions. Further research is needed to explore the potential of using GIS and other mapping technologies to monitor and manage rubber plant diseases.

Frequently Asked Questions (FAQs) about White Root Mushroom Diseases (JAP) on People's Rubber Plantations in Asahan Regency

Q: What is White Root Mushroom Disease (JAP)?

A: White Root Mushroom Disease (JAP) is a serious threat to rubber plants, caused by the fungus Rigidoporus Microporus. It infects the roots of rubber trees, leading to a range of symptoms, including yellowing of leaves, stunted growth, and eventually, the death of the tree.

Q: What are the symptoms of JAP?

A: The symptoms of JAP include:

  • Yellowing of leaves
  • Stunted growth
  • Wilting of leaves
  • Death of the tree

Q: How is JAP spread?

A: JAP is spread through the roots of infected trees, and can also be spread through contaminated soil and water.

Q: What are the environmental factors that contribute to the spread of JAP?

A: The environmental factors that contribute to the spread of JAP include:

  • Height
  • Humidity
  • Soil type

Q: How can farmers prevent the spread of JAP?

A: Farmers can prevent the spread of JAP by:

  • Practicing good agricultural practices, such as regular pruning and fertilization
  • Using fungicides to control the spread of the disease
  • Implementing integrated pest management (IPM) strategies
  • Monitoring the health of their trees regularly

Q: What is the role of GIS in disease mapping?

A: GIS (Geographic Information System) is a powerful tool that allows farmers and researchers to map the distribution of diseases, such as JAP, and make informed decisions about disease management.
