The Influence of Height and Slope on Rubber Production in the Hapesong Garden of PTPN III South Tapanuli

Introduction

Rubber production is a significant contributor to the economy of many countries, particularly in Southeast Asia. The Hevea brasiliensis Muell. Arg. tree is the primary source of natural rubber, and its cultivation requires specific conditions to ensure optimal production. The hapesong garden, located in the Batang Toru District of South Tapanuli, is one of the major rubber-producing areas in Indonesia. However, the productivity of rubber plants in this region is affected by various factors, including the height of the place and slope of the slope.

Research Methodology

A research study was conducted in the hapesong garden in July-August 2013 to investigate the effect of the height of the place and slope on rubber production. The free survey method was used to collect data, with the main variable being the height and slope of the slope. The data analysis was carried out using regression methods and geographic information systems (GIS).

Results

The results of the study showed that the height of the place and slope had a significant effect on the decrease in rubber production. The higher the location of the garden and the steeper the slope, the lower the rubber production produced. The interaction between the height and slope of the slope did not show a significant effect.

Deeper Analysis

The results of this study provide an important picture of the factors that influence the productivity of rubber plants in the hapesong garden. A higher height of place and a steep slope can cause several issues that affect rubber production:

Water Availability: At a higher height, rainfall tends to be higher. However, the soil on a steep slope has a faster drainage that triggers the loss of soil moisture and reduces the availability of water for plants.

Temperature: Air temperature tends to be lower in a higher place. Colder temperatures can inhibit the growth of rubber plants and reduce the production of sap.

Soil Fertility: The soil on steep slopes tends to be thinner and easily eroded. This can reduce the nutritional content important for the growth of rubber plants.

The Importance of Further Investigation

Although this study shows the significant effect of the height and slope of the slope on rubber production, further research on the properties of soil fertility is very necessary. Factors such as soil acidity (pH), organic matter content, and the availability of important nutrients such as nitrogen, phosphorus, and potassium, also need to be investigated to get a more comprehensive understanding of the factors that affect the productivity of rubber plants in the hapesong garden.

Conclusion

This study provides an initial foundation for understanding the effect of topographic factors on the production of rubber plants in the hapesong garden. By paying attention to the height factor of the place and slope of the slope, as well as conducting further analysis of soil fertility, it is expected to increase the productivity of rubber plants and support the sustainability of rubber cultivation in the region.

Recommendations

Based on the findings of this study, the following recommendations are made:

Conduct further research on soil fertility: Investigate the properties of soil fertility, including soil acidity (pH), organic matter content, and the availability of important nutrients such as nitrogen, phosphorus, and potassium.
Implement soil conservation measures: Implement measures to prevent soil erosion and improve soil fertility, such as terracing and contour farming.
Monitor and manage water availability: Monitor and manage water availability to ensure that rubber plants receive adequate water for optimal growth and production.
Develop strategies to mitigate the effects of temperature: Develop strategies to mitigate the effects of temperature on rubber plant growth and production, such as using shade cloth or other temperature management techniques.

By implementing these recommendations, it is expected that the productivity of rubber plants in the hapesong garden will increase, and the sustainability of rubber cultivation in the region will be supported.

Limitations of the Study

This study has several limitations that should be noted:

Limited sample size: The sample size of this study was limited to the hapesong garden, which may not be representative of other rubber-producing areas in the region.
Limited data collection: The data collection was limited to the height and slope of the slope, and did not include other factors that may affect rubber production, such as soil fertility and water availability.
Limited analysis: The analysis was limited to regression methods and GIS, and did not include other analytical techniques that may provide a more comprehensive understanding of the factors that affect rubber production.

Future Research Directions

Future research should focus on addressing the limitations of this study and exploring new research directions, such as:

Investigating the effects of soil fertility on rubber production: Conduct further research on the properties of soil fertility and its effects on rubber production.
Developing strategies to mitigate the effects of temperature: Develop strategies to mitigate the effects of temperature on rubber plant growth and production.
Exploring new rubber-producing areas: Explore new rubber-producing areas in the region and investigate the factors that affect rubber production in these areas.

By addressing the limitations of this study and exploring new research directions, it is expected that a more comprehensive understanding of the factors that affect rubber production in the hapesong garden will be gained, and the sustainability of rubber cultivation in the region will be supported.
