The problem in the image appears to be about determining the limit of the following expression:

\[
\lim_{{x \to 2}} \frac{(3x - 1)^3 - (x + 3)^3}{x^3 - 8}
\]

### Solution Steps:

1. **Direct Substitution (Substitusi Langsung)**:
   - First, substituting \( x = 2 \) directly into the expression gives:

   \[
   \lim_{{x \to 2}} \frac{(3(2) - 1)^3 - (2 + 3)^3}{2^3 - 8} = \frac{(5)^3 - (5)^3}{8 - 8} = \frac{125 - 125}{0} = \frac{0}{0}
   \]
   
   This results in an indeterminate form \( \frac{0}{0} \), so we need to manipulate the expression further.

2. **Factoring the Expression**:
   - To resolve the indeterminate form, the expression can be factored.
   - Expanding \( (3x - 1)^3 \) and \( (x + 3)^3 \) gives:

   \[
   (3x - 1)^3 = 27x^3 - 27x^2 + 9x - 1
   \]
   \[
   (x + 3)^3 = x^3 + 9x^2 + 27x + 27
   \]

   So, the numerator becomes:
   
   \[
   (27x^3 - 27x^2 + 9x - 1) - (x^3 + 9x^2 + 27x + 27) = 26x^3 - 36x^2 - 18x - 28
   \]

   Factoring this expression out of common terms:
   
   \[
   2(x - 2)(13x^2 + 8x + 7)
   \]

3. **Simplifying the Denominator**:
   - The denominator \( x^3 - 8 \) can be factored as:

   \[
   x^3 - 8 = (x - 2)(x^2 + 2x + 4)
   \]

4. **Canceling Common Terms**:
   - Now, we can cancel \( (x - 2) \) from both the numerator and denominator:

   \[
   \lim_{{x \to 2}} \frac{2(x - 2)(13x^2 + 8x + 7)}{(x - 2)(x^2 + 2x + 4)} = \lim_{{x \to 2}} \frac{2(13x^2 + 8x + 7)}{x^2 + 2x + 4}
   \]

5. **Substitute \( x = 2 \) Again**:
   - Now, substitute \( x = 2 \) into the simplified expression:

   \[
   \frac{2(13(2)^2 + 8(2) + 7)}{(2)^2 + 2(2) + 4} = \frac{2(13(4) + 16 + 7)}{4 + 4 + 4} = \frac{2(52 + 16 + 7)}{12} = \frac{2(75)}{12} = \frac{150}{12} = \frac{25}{2}
   \]

Thus, the final value of the limit is:

\[
\boxed{\frac{25}{2}}
\]
