The Quality of City Waste Compost and Its Applications on Critical Land Media for Sengon Seeds (Paraserianthes Falcataria)

Introduction

The issue of critical land in Indonesia is a pressing concern, with approximately 28 million hectares of land affected. This condition requires replanting and soil quality improvement using compost from city waste, particularly for sengon seeds (Paraserianthes falcataria). This study aims to compare the quality of city waste compost produced using the composting process with and without EM4, as well as analyzing the effect of the compost on the growth of sengon seeds planted on critical land media.

Background

Critical land in Indonesia is a significant problem that requires immediate attention. The condition of critical land is characterized by soil degradation, reduced fertility, and decreased biodiversity. This condition not only affects the environment but also has a negative impact on the economy and human well-being. The use of compost from city waste is a potential solution to improve soil quality and support the growth of sengon seeds, which has the potential to be a solution for reforestation.

Methodology

This study was conducted from November 2009 to April 2010 at Rumah Jala, Faculty of Agriculture, University of North Sumatra, using a complete random factorial design. The study involved the comparison of two types of compost: compost produced using the composting process with EM4 and compost produced traditionally without EM4. The results of the study were analyzed to determine the effect of the compost on the growth of sengon seeds.

Results

The results of the study showed that compost from city waste processed with EM4 has better quality compared to the compost produced traditionally without EM4. This positive effect can be seen from high growth, stem diameter, and number of leaves in sengon seeds, which are much better in treatment that uses EM4 compost. More specifically, the treatment G (NPK + 10 g compost with EM4) and the treatment H (NPK + 15 g compost with EM4) shows more optimal results than other treatments, including treatment without compost EM4. Treatment D (NPK + 15 g of traditional compost) and E (NPK + 20 g of traditional compost) also show better results than without compost control.

Discussion

Further analysis shows that the use of EM4 in the city waste composting process can improve the quality of nutrients in the compost. EM4 functions as an effective decomposing microorganism, so that it can increase the composting process by reducing decomposition time and increasing nutrient content needed for plant growth. The application of this study is very relevant for the rehabilitation efforts of critical land in Indonesia. By utilizing quality compost from city waste, not only improves the condition of the soil, but also supports the growth of sengon seeds which has the potential to be a solution for reforestation.

Conclusion

Overall, this research provides an important insight into the application of compost from city waste in the context of the environment and sustainable agriculture. This initiative is not only beneficial for the environment, but can also be a model for better waste management practices, which in turn can support greening and sustainability programs in Indonesia. The use of EM4 in the city waste composting process can improve the quality of nutrients in the compost, which can support the growth of sengon seeds and improve soil quality.

Recommendations

Based on the results of this study, it is recommended that the use of EM4 in the city waste composting process be implemented on a larger scale to support the rehabilitation efforts of critical land in Indonesia. Additionally, further research is needed to explore the potential of sengon seeds as a solution for reforestation and to develop more effective methods for composting city waste.

Limitations

This study has several limitations, including the small sample size and the limited scope of the study. Additionally, the study only focused on the use of EM4 in the city waste composting process and did not explore other potential solutions for improving soil quality and supporting the growth of sengon seeds.

Future Research Directions

Future research should focus on exploring the potential of sengon seeds as a solution for reforestation and developing more effective methods for composting city waste. Additionally, further research is needed to explore the potential of EM4 in other applications, such as improving soil quality and supporting the growth of other plant species.
