Diversity of Macrophatewater Plants in Lake Toba, Onan Runggu District, Samosir Regency
Introduction
Lake Toba, located in the Onan Runggu District of Samosir Regency, is one of the largest lakes in Southeast Asia. The lake's unique ecosystem supports a diverse range of aquatic plants, which play a crucial role in maintaining the health of the lake's ecosystem. However, the diversity of macrophate aquatic plants in Lake Toba has not been extensively studied. This research aims to analyze the diversity of aquatic plants in Lake Toba, evaluate their potential as weeds, and examine the relationship between their diversity and physical and chemical factors of the lake.
Background
Macrophate aquatic plants are a type of aquatic plant that grows in freshwater environments. They are an essential component of aquatic ecosystems, providing food and shelter for various aquatic species. However, some macrophate aquatic plants can become invasive and cause harm to the ecosystem. In Lake Toba, the diversity of macrophate aquatic plants is influenced by various physical and chemical factors, including light intensity, light penetration, and dissolved oxygen levels.
Research Methodology
This study employed a purposive sampling method, where four stations were selected based on their activities around the location. The stations were:
- Station 1: Port area
- Station 2: Washing area
- Station 3: Natural area
- Station 4: Agricultural area
The data analyzed included:
- Percent of plant type cover
- Dominance index
- Diversity index
The physical-chemical parameters measured included:
- Temperature
- Light intensity
- Light penetration
- pH
- Dissolved oxygen (DO)
- BOD5
- NO3
- PO4
- Oxygen saturation
Findings and Analysis
This study identified seven types of aquatic plants classified into seven genera:
- Potamogeton
- Vallisneria
- Eichornia
- Myriophyllum
- Hydrilla
- Limnocharis
- Ludwigia
The Vallisneria Gigantea species showed the highest population at stations 1, 2, and 3, while the Eichornia Crassipes species had the highest population at station 4.
The diversity index obtained showed that station 1 had the highest value (0.897), while station 3 had the lowest value (0.0121). This indicates that station 1 has a higher diversity of species compared to station 3, which may be caused by more intense human activities around the station.
Relationship with Physics-Chemical Factors
Further analysis revealed a strong relationship between the diversity of aquatic plants and physical-chemical factors, particularly light intensity, light penetration, and dissolved oxygen levels. This suggests that environmental conditions such as lighting and water quality significantly affect the growth and diversity of aquatic plants in Lake Toba.
Conclusion
This study provides valuable insights into the diversity of macrophate aquatic plants in Lake Toba. By understanding the relationship between species diversity and environmental factors, conservation efforts and water management can be done more effectively. Further research is expected to explore the potential of aquatic plants as weeds and their functions in the Lake Toba aquatic ecosystem.
Importance of Preserving Lake Toba
The diversity of types of aquatic plants not only contributes to the health of ecosystems but is also important for community economic activities, such as tourism and fisheries. Therefore, it is essential to preserve Lake Toba and ensure the diversity of aquatic plants is maintained for future generations.
