The Impact of PLTU Cooling Water Temperature on Chlorophyll Content in the Sicanang Belawan River

Introduction

The Sicanang Belawan River is a vital component of the aquatic ecosystem, supporting a diverse range of plant and animal life. Chlorophyll, a green pigment found in plants, plays a crucial role in the process of photosynthesis, which is essential for the survival of aquatic ecosystems. The temperature of the cooling water discharged from the Steam Power Plant (PLTU) into the Sicanang Belawan River has been a topic of concern, as it can have a significant impact on the chlorophyll content in the river water. This study aims to examine the effect of the temperature of the PLTU cooling water on the chlorophyll content in the Sicanang Belawan River.

Background

Chlorophyll is a vital component of photosynthesis, which is the process by which plants convert sunlight into energy. The level of chlorophyll in aquatic ecosystems can be used as an indicator of the productivity of the ecosystem. A decrease in chlorophyll levels can indicate a decline in the health of the ecosystem, which can have far-reaching consequences for the entire food chain. The temperature of the cooling water discharged from the PLTU can have a significant impact on the chlorophyll content in the Sicanang Belawan River, as it can alter the chemical composition of the water and affect the growth and survival of aquatic plants.

Methodology

The methods used in this study include river water sampling, filtering, and washing with acetone. The sample is then centrifuged and the results are measured using the visible light spectrophotometer at a wavelength of 630 Nm, 645 Nm, and 665 Nm. The study was conducted at three different points: the control point of 100 meters before the refusal of the cooling water, the cooling water point, and the control point of 100 meters after disposal. The water temperature and chlorophyll levels were measured at each point to determine the impact of the PLTU cooling water temperature on the chlorophyll content in the Sicanang Belawan River.

Results

The results of this study showed that there were significant differences in chlorophyll levels in the Sicanang Belawan River before and after the drainage of the PLTU cooling water. At the control point of 100 meters before the refusal of the cooling water, the chlorophyll content was recorded at 4,9075 mg/m³ with a river water temperature of 29 ° C. At the cooling water point, the chlorophyll level decreased dramatically to 1,0613 mg/m³ with a water temperature increase to 33 ° C. At the control point of 100 meters after disposal, the chlorophyll levels increased slightly to 1,3085 mg/m³ with a water temperature of 31 ° C. Interestingly, at the control point of 200 meters after exhaust, the chlorophyll levels increased again to 2,9175 mg/m³ with a water temperature of 31 ° C. This shows that the impact of cooling water temperatures on chlorophyll content is not always linear.

Discussion

The results of this study indicate that the temperature of the PLTU cooling water discharged into the Belawan Sicanang River has a significant effect on chlorophyll levels in river water. An increase in water temperature can cause a decrease in chlorophyll levels, which in turn can interfere with the balance of aquatic ecosystems. This is a concern, as a decline in chlorophyll levels can have far-reaching consequences for the entire food chain. It is essential to note that this research only analyzes the impact of cooling water temperatures on chlorophyll levels. Other factors such as water quality, the presence of pollutants, and the condition of the surrounding environment can also affect the condition of the Sicanang Belawan River ecosystem.

Conclusion

Based on the results of this study, it can be concluded that the temperature of the PLTU cooling water discharged into the Belawan Sicanang River has a significant effect on chlorophyll levels in river water. An increase in water temperature can cause a decrease in chlorophyll levels, which in turn can interfere with the balance of aquatic ecosystems. Further research is needed to understand more comprehensively the impact of the disposal of PLTU cooling water on the Sicanang Belawan River ecosystem. The data obtained can be used to formulate effective and sustainable environmental management strategies to maintain the sustainability of aquatic ecosystems.
