Introduction

Hydrilla (hydrilla verticilatta l.f.royle), a water weed that is often considered a scourge for aquatic ecosystems, has been found to store extraordinary potential as an organic fertilizer. A study has been conducted to investigate the effect of composting time on carbon and nitrogen content in hydrilla compost, which has opened up the possibility of using it as an environmentally friendly fertilizer. This study is significant as it reveals the potential of hydrilla as a valuable source of nutrition to increase soil fertility and minimize the use of chemical fertilizers.

Methodology

The study involved random sampling of hydrilla from Parapat Beach. The sample was then dried before being processed using EM4 bacteria and composted in a variety of times, ranging from 2 to 20 days. The organic carbon content was determined using the Walkley Black method, while the nitrogen content was measured by the Kjeldahl method. The results of the study show a significant decrease in organic carbon content along with composting time.

Organic Carbon Content

The organic carbon content of the hydrilla compost was found to decrease significantly with increasing composting time. On the 0th day, the organic carbon content reached 42.648%, which is a high value. However, this value decreased to 14.471% on the 20th day. This decrease in organic carbon content indicates that the decomposition process causes carbon release gradually, making the hydrilla compost rich in nutrients.

Nitrogen Content

Similar trends were observed in the nitrogen content, which decreased from 1.502% on the 0th day to 1.366% on the 20th day. This decrease in nitrogen content also indicates that the decomposition process causes nitrogen release gradually, making the hydrilla compost rich in nutrients.

Importance of the Study

The importance of this study lies in the discovery that the hydrilla compost that was composted for 20 days had an ideal C/N ratio, which is 10.59. This value is within the ideal range for the soil (10-12), which allows hydrilla compost to release nutrients gradually and effectively. This optimal C/N ratio is crucial for the use of hydrilla as a source of organic fertilizer, as it ensures that the compost is rich in nutrients and can be absorbed by plants effectively.

Implications of the Study

The findings of this study have important implications for the use of hydrilla as a source of organic fertilizer. Instead of being a problem, hydrilla can be converted into a valuable source of nutrition to increase soil fertility and minimize the use of chemical fertilizers. This study also opened up opportunities to optimize the process of composting hydrilla to produce better quality compost and meet the nutritional needs of plants.

Management of Water Weeds

In addition, this research can be a guide for the management of water weeds, especially hydrilla. By utilizing the potential of hydrilla as organic fertilizer, we can reduce the negative impact on aquatic ecosystems and optimize the use of natural resources. This study highlights the importance of finding alternative uses for water weeds, which can help to mitigate the negative impacts of their presence in aquatic ecosystems.

Conclusion

In conclusion, this study has revealed the potential of hydrilla as a valuable source of nutrition to increase soil fertility and minimize the use of chemical fertilizers. The findings of this study have important implications for the use of hydrilla as a source of organic fertilizer and can be a guide for the management of water weeds, especially hydrilla. Further research is needed to optimize the process of composting hydrilla to produce better quality compost and meet the nutritional needs of plants.
