by ADMIN 123 views

Introduction

Samosir Island, located in Indonesia, is a region with immense potential as a source of forage for ruminants. The island is home to numerous natural grazing fields, teeming with various types of vegetation. This study aims to identify the location of natural grasslands, analyze the potential of forage production, livestock capacity, forage carrying capacity index, the capacity to add ruminant livestock populations, and botanical compositions based on land capabilities and land use class.

Background

Natural grasslands play a vital role in supporting livestock production, providing essential nutrients and feed for ruminant animals. However, the sustainability of these grasslands is often threatened by factors such as overgrazing, land degradation, and climate change. In Samosir Island, the potential of natural grasslands as a source of forage for ruminants has not been fully explored. This study seeks to address this knowledge gap by analyzing the forage potential of natural grasslands on the island.

Research Methods

The method used in this study is a field survey, which involved collecting data on land capability class, land use, forage production, and botanical composition of natural grasslands on Samosir Island. The results of this survey show that the location of natural grasslands on Samosir Island is dominated by the IV Land Capability Class (93.65%). In addition, most of these areas are also located under the use of dry land agricultural land (57.14%) and open land (36.51%). The production of forage dry materials produced reached 85,950,392.46 kg per year, with a capacity of livestock of 26,912.06 Animal Unit (ST).

Data Collection

The data collection process involved conducting a field survey of natural grasslands on Samosir Island. The survey involved collecting data on land capability class, land use, forage production, and botanical composition of the grasslands. The data was collected using a combination of methods, including:

  • Land capability class: The land capability class was determined using the Indonesian National Soil Map (INSM).
  • Land use: The land use was determined using remote sensing and GIS techniques.
  • Forage production: The forage production was determined using a combination of methods, including yield measurements and remote sensing.
  • Botanical composition: The botanical composition was determined using a combination of methods, including plant identification and remote sensing.

Main Findings

Based on the analysis conducted, the additional capacity of ruminant livestock populations was recorded at 4,702.45 ST. However, although the potential for forage production is quite large, the forage carrying capacity index shows a value of 1.21, which indicates that the availability of forage is in the critical category. This reflects the need for immediate action to improve the condition of the grasslands in the area in order to better support livestock maintenance.

Forage Carrying Capacity Index

The forage carrying capacity index is a critical indicator of the sustainability of natural grasslands. The index is calculated using a combination of methods, including forage production, land capability class, and land use. In this study, the forage carrying capacity index was calculated using the following formula:

Forage Carrying Capacity Index (FCCI) = (Forage Production / Land Capability Class) x (Land Use / 100)

The FCCI value of 1.21 indicates that the availability of forage is in the critical category, reflecting the need for immediate action to improve the condition of the grasslands in the area.

Botany Composition

In terms of botanical composition, grasslands in the Class of Land Capability IV have more diversity of forage types compared to land capability class II. In the class of land capability IV, there were 34 types of forage with dominant species, namely Axonopus compressus. Meanwhile, in the Land Capability Class II found only 11 types of forage, with the dominant species is Imperata Cylindrica. This diversity shows a greater potential for the development of grasslands in the land capability class IV.

Diversity of Forage Types

The diversity of forage types is a critical indicator of the potential of natural grasslands as a source of forage for ruminants. In this study, the diversity of forage types was determined using a combination of methods, including plant identification and remote sensing. The results show that grasslands in the Class of Land Capability IV have more diversity of forage types compared to land capability class II.

Conclusion

Overall, the results of the study showed that natural grasslands on Samosir Island are in the critical category and require attention and improvement to increase feed capacity for ruminant livestock. To maintain the sustainability of forage resources, better rehabilitation and management efforts must be carried out, including increasing the diversity of existing feed plants. With the right strategy, the great potential of Samosir grasslands as a source of animal feed can be utilized optimally, increasing livestock productivity and supporting the welfare of local farmers.

Recommendations

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

  • Rehabilitation of grasslands: Efforts should be made to rehabilitate degraded grasslands and improve their condition to increase feed capacity for ruminant livestock.
  • Management of grasslands: Effective management practices should be implemented to maintain the sustainability of forage resources, including increasing the diversity of existing feed plants.
  • Development of forage production: Efforts should be made to develop forage production in the region, including the establishment of forage plantations and the improvement of forage yields.

By implementing these recommendations, the great potential of Samosir grasslands as a source of animal feed can be utilized optimally, increasing livestock productivity and supporting the welfare of local farmers.
