**Restoring severe eroded soil with compost Chromolaena odorata and *Tithonia diversifolia ***

Severe eroded land is a serious problem faced in various regions, including in Silimakuta District, Simalungun Regency. Soil erosion causes loss of fertile soil layers, thereby reducing soil quality and plant productivity. To overcome this problem, this study examines the use of compost * chromolaena odorata * and * tithonia diversifolia * as an enforcement of severe chemical chemical properties.

The study was conducted using a non-factorial random design consisting of 10 treatments with 3 replications. The treatment applied includes:

Control (without compost)
Compost * Tithonia diversifolia * (TD) with a dose of 20 tons/ha and composting time:
- TDW0 (0 days)
- TDW1 (14 days)
- TDW2 (28 days)
Compost * chromolaena odorata * (Co) with a dose of 20 tons/ha and composting time:
- Guy (0 days)
- Cow1 (14 days)
- Cow2 (28 days)
Combination of compost * Tathonia diversifolia * (TD) and * Chromolaena odorata * (Co) with a dose of 20 tons/ha and composting time:
- Tdcow0 (0 days)
- TDCOW1 (14 days)
- TDCOW2 (28 days)

The results showed that the use of compost *tithonia diversifolia *, *chromolaena odorata *, and its combination had a significant positive impact on increasing soil chemical properties, such as pH, n-total, p-available, k-dd, c-organic, and c /N. In addition, the use of compost also increases plant height, root weight, and corn harvest yields.

However, it should be noted that the use of compost does not have a significant impact on soil cation exchange capacity.

Chromolaena Odorata (Kirinyaga)

This plant is a weed that easily grows and develops rapidly in various tropical regions. Although considered a weed, * Chromolaena odorata * has the potential as a raw material for compost. This plant is rich in nutrients, such as nitrogen, phosphorus, and potassium, which can be beneficial for plant growth.

Tithonia diversifolia (Mexican sunflower)

This plant has great potential as a raw material for compost because it contains a lot of nutrients and can increase soil fertility. * Tithonia diversifolia* also has the ability to improve soil structure, so as to increase water infiltration and reduce soil erosion.

**Benefits of using compostChromolaena odorataand*Tithonia diversifolia ***

The use of compost of these two types of plants has a number of benefits, including:

Increasing soil fertility

Compost contains important nutrients needed by plants, such as nitrogen, phosphorus, and potassium. The addition of compost can increase soil fertility and support better plant growth.

Improve soil structure

Compost can help improve soil structure, making it more loose and porn. This increases water infiltration, soil aeration, and drainage, so that the roots of plants can grow well.

Increasing plant resilience to disease

Compost can help increase plant resistance to diseases and pests. This is because compost can increase the population of microorganisms useful in the soil, which can control pathogens and improve plant health.

Preventing soil erosion

Compost can help prevent soil erosion by improving soil structure and increasing the ability of soil to absorb water.

Conclusion

This study shows that the use of compost * chromolaena odorata * and * tithonia diversifolia * can be an effective solution to improve the chemical properties of severe eroded soil in Silimakuta District, Simalungun Regency.

The use of compost can not only increase soil fertility and yields, but also has a positive impact on the environment, such as prevention of erosion and increasing plant resilience to disease.

Further research needs to be done to examine the optimal dose and the ideal composting time to achieve maximum results.

Recommendations

Based on the results of this study, the following recommendations can be made:
