The question provided seems to be in Indonesian, and it appears to deal with logic, specifically propositional logic.

The question reads:

**5. Diketahui bahwa nilai kebenaran dari \( a \Rightarrow b \) adalah S (salah). Apakah yang dapat anda katakan tentang nilai kebenaran dari \( \neg a \land b \iff a \lor b \)?**

Translation to English:
**5. It is known that the truth value of \( a \Rightarrow b \) is False. What can you say about the truth value of \( \neg a \land b \iff a \lor b \)?**

### Step-by-Step Solution:

1. **Given Information**: \( a \Rightarrow b \) is False.
   - For an implication \( a \Rightarrow b \) to be False, \( a \) must be True and \( b \) must be False. This is because the only case when an implication is False is when the first part (antecedent) is True and the second part (consequent) is False.

   Therefore, \( a = \text{True} \) and \( b = \text{False} \).

2. **Expression to Evaluate**: \( \neg a \land b \iff a \lor b \).

   Let's break this down:

   - \( \neg a \): The negation of \( a \), so \( \neg a = \text{False} \) (since \( a = \text{True} \)).
   - \( b \): We already know \( b = \text{False} \).
   - \( \neg a \land b \): This is \( \text{False} \land \text{False} = \text{False} \).
   - \( a \lor b \): This is \( \text{True} \lor \text{False} = \text{True} \).

   So, we now have: \( \text{False} \iff \text{True} \).

3. **Truth Value of \( \iff \)**:
   - The biconditional \( \iff \) (if and only if) is True when both sides have the same truth value.
   - In this case, \( \text{False} \iff \text{True} = \text{False} \).

### Conclusion:
The truth value of \( \neg a \land b \iff a \lor b \) is **False**.

Do you need any further details or clarifications?

### Here are 5 related questions to consider:
1. How do we determine the truth value of \( a \Rightarrow b \) for different truth values of \( a \) and \( b \)?
2. What is the meaning of \( \land \) (AND) and \( \lor \) (OR) in propositional logic?
3. How does the truth value of \( \neg a \land b \iff a \lor b \) change when both \( a \) and \( b \) are False?
4. Can you explain the truth table for a biconditional \( \iff \)?
5. What are the possible truth values for more complex logical statements involving negation, conjunction, disjunction, and biconditional?

### Tip:
When solving propositional logic problems, always begin by determining the truth values of individual components before evaluating the entire expression.

Diketahui bahwa nilai kebenaran dari a => b adalah S (salah). Apakah yang dapat anda katakan tentang nilai kebenaran dari ¬a ∧ b <=> a ∨ b?

In this propositional logic problem, you will explore the truth value of ¬a ∧ b <=> a ∨ b given that a => b is false. This problem covers key logical concepts like implication, negation, conjunction, disjunction, and biconditional statements.
