The Carrying Capacity of the Lake Siais Environment for Floating Net Cage Activities

Introduction

Lake Siais, a natural wonder with great potential for fisheries activities, particularly fish farming through floating net cages (KJA), requires a thorough understanding of its environmental carrying capacity to preserve the lake ecosystem. Research conducted in January-June 2013 aimed to expose environmental conditions and the carrying capacity of Lake Siais on KJA activities. This study employed the purposive sampling method, with sampling points determined based on the lake's environmental characteristics.

Methodology

Physical, chemical, and biological water parameters, such as temperature, brightness, dissolved oxygen (DO), pH, total phosphate, nitrate, COD, BOD5, and plankton, were measured in situ and in the laboratory. The analysis of environmental carrying capacity was carried out using the Cads Tool method. This study aimed to provide an important picture of the environmental conditions of the Lake Siais and its ability to support KJA activities.

Results

The results showed that the parameters of Lake Siais water quality were still within the standard limit of class 3 PP water quality No. 82 of 2001, which is needed for fisheries cultivation activities. This condition indicates the quality of Lake Siais still supports the life of aquatic organisms. The carrying capacity analysis using the Cads Tool method produced a carrying capacity of 1,965,6337 tons/year. This means that Lake Siais is still able to support KJA activities with a production capacity of up to 1,965,6337 tons of fish per year.

The Importance of Understanding the Carrying Capacity of the Environment

Understanding the carrying capacity of the environment is crucial for the sustainability of KJA activities. However, it should be understood that the carrying capacity of the environment is not a static number that remains forever. Several factors can affect the carrying capacity of the environment, such as:

Increased KJA Activity: If the amount of KJA in the lake Siais increases without control, it can cause a buildup of organic waste, decreased water quality, and ultimately has a negative impact on the carrying capacity of the environment.
Climate Change: Climate change can cause changes in rainfall patterns and water temperatures, which in turn have an impact on water quality and environmental carrying capacity.
Human Activity around the Lake: Pollution from settlements, industry, and agriculture around the lake can pollute water and reduce the carrying capacity of the environment.

Important Steps to Preserve the Lake Siais

To maintain the sustainability of Lake Siais and support the sustainability of KJA activities, several important steps need to be taken:

Regulation of the Number of KJA: The government and lake managers need to regulate the number and capacity of KJA operating in the lake soil so as not to exceed the environmental carrying capacity.
Improving Aquaculture Technology: The use of environmentally friendly aquaculture technology, such as a biofloc system, can help reduce organic waste and increase cultivation efficiency.
Increasing Public Awareness: Increasing community awareness around the lake regarding the importance of maintaining the cleanliness and sustainability of the lake environment.
Periodic Monitoring: Water quality monitoring and the carrying capacity of the Lake Siais environment periodically need to be done to ensure environmental conditions are maintained and support the sustainability of KJA activities.

Conclusion

Understanding and managing the carrying capacity of the Lake Siais environment well will ensure the sustainability of KJA activities and preserve the lake ecosystem for future generations. It is essential to take the necessary steps to maintain the sustainability of Lake Siais and support the sustainability of KJA activities.

Recommendations

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

The government and lake managers need to regulate the number and capacity of KJA operating in the lake soil.
The use of environmentally friendly aquaculture technology should be promoted.
Community awareness around the lake regarding the importance of maintaining the cleanliness and sustainability of the lake environment should be increased.
Periodic monitoring of water quality and the carrying capacity of the Lake Siais environment should be conducted.

Future Research Directions

Future research should focus on:

Investigating the impact of climate change on the carrying capacity of the Lake Siais environment.
Developing environmentally friendly aquaculture technology for KJA activities.
Conducting periodic monitoring of water quality and the carrying capacity of the Lake Siais environment.

Limitations of the Study

This study has several limitations, including:

The study was conducted in a specific time period and may not be representative of other time periods.
The study only focused on the carrying capacity of the Lake Siais environment and did not consider other factors that may affect KJA activities.

Conclusion

In conclusion, this study provides an important picture of the environmental conditions of the Lake Siais and its ability to support KJA activities. Understanding and managing the carrying capacity of the Lake Siais environment well will ensure the sustainability of KJA activities and preserve the lake ecosystem for future generations.
