Revealing the Potential of the Snake River: Analysis of Primary Phytoplankton Productivity

Introduction

Research on the primary productivity of aquatic ecosystems, especially phytoplankton, is an essential aspect in understanding the health and potential utilization of natural resources in a sustainable manner. The Snake River, located in Deli Serdang Regency, is an interesting object of research to uncover the potential of natural resources in the region. This study was conducted during June to August 2014 with a focus on primary phytoplankton productivity and its relationship with physical and chemical factors in the river.

Phytoplankton, as the primary producers of aquatic ecosystems, play a crucial role in the food chain and water quality. Understanding their productivity is essential in managing and conserving aquatic ecosystems. The Snake River, with its unique characteristics and location, provides an ideal setting for studying phytoplankton productivity. This study aims to investigate the primary phytoplankton productivity in the Snake River and its relationship with physical and chemical factors.

Methodology

This study uses the purposive sampling method by taking samples from three points in the Snake River. Primary phytoplankton productivity is measured by the oxygen method, which is a widely used technique for measuring phytoplankton productivity. The oxygen method involves measuring the amount of oxygen produced by phytoplankton during photosynthesis.

The sampling points were selected based on their location and characteristics. The first sampling point was located near the mouth of the river, while the second and third points were located upstream. The samples were collected during the peak of the dry season, which is from June to August.

Results

The results of this study showed a range of phytoplankton primary productivity in the Snake River, with values ranging from 225,216 to 394,128 mgc/m3/day. The highest value was found at the second sampling point, while the lowest value was at the first point.

The results also showed a strong relationship between primary phytoplankton productivity and several physical and chemical factors, including:

Abundance of phytoplankton: A very strong positive correlation was found between phytoplankton abundance and primary productivity.
Nitrates: A very strong positive correlation was found between nitrate levels and primary productivity.
Dissolved oxygen (DO): A very strong positive correlation was found between DO levels and primary productivity.
Penetration of light: A very strong positive correlation was found between light penetration and primary productivity.
Current: A very strong positive correlation was found between current speed and primary productivity.
Phosphate: A strong positive correlation was found between phosphate levels and primary productivity.

These findings indicate that physical and chemical factors play an important role in determining the primary productivity of phytoplankton in the Snake River. The availability of nutrients such as nitrate and phosphate, as well as supporting environmental conditions such as light penetration, water currents, and oxygen levels, greatly affects the growth and activity of photosynthesis of phytoplankton.

Discussion

The results of this study provide valuable information to understand the dynamics of the snake river ecosystem and its potential use. Increasing primary phytoplankton productivity can contribute to the food chain in the river, support the fish population, and maintain water quality. However, keep in mind that changes in environmental conditions such as pollution and climate change can affect phytoplankton productivity.

Therefore, efforts to conservation and management of the Snake River are very important to ensure the preservation of ecosystems and their benefits for the community. This study highlights the importance of understanding the relationship between phytoplankton productivity and physical and chemical factors in the Snake River.

Conclusion

In conclusion, this study provides valuable information on the primary phytoplankton productivity in the Snake River and its relationship with physical and chemical factors. The results show a strong relationship between phytoplankton productivity and several physical and chemical factors, including abundance of phytoplankton, nitrates, dissolved oxygen, penetration of light, current, and phosphate.

The findings of this study have important implications for the management and conservation of the Snake River ecosystem. Understanding the relationship between phytoplankton productivity and physical and chemical factors can help in developing effective strategies for managing and conserving the ecosystem.
