The text in the image provides the following information:

- Tatik borrows Rp. 5,000,000 from an employee cooperative at a fixed interest rate.
- Tatik repays the loan over 10 months, and the total repayment becomes Rp. 5,500,000.
- The task is to determine the monthly interest rate (suku bunga per bulan).

### Solution

To determine the monthly interest rate:

1. **Initial loan**: Rp. 5,000,000
2. **Total repayment**: Rp. 5,500,000
3. **Time period**: 10 months
4. **Interest (total amount over the principal)**:
   \[
   \text{Interest} = \text{Total Repayment} - \text{Loan Principal}
   \]
   \[
   \text{Interest} = 5,500,000 - 5,000,000 = Rp. 500,000
   \]

5. **Monthly interest rate**:
   We can calculate the total interest as a percentage of the original loan and then divide by 10 months to get the monthly interest rate.
   \[
   \text{Monthly Interest Rate} = \left( \frac{\text{Total Interest}}{\text{Principal} \times \text{Time}} \right) \times 100
   \]
   \[
   \text{Monthly Interest Rate} = \left( \frac{500,000}{5,000,000 \times 10} \right) \times 100
   \]
   \[
   \text{Monthly Interest Rate} = \frac{500,000}{50,000,000} \times 100 = 1\%
   \]

### Conclusion:
The monthly interest rate is **1%**.
