The problem reads:

**Jika 3 pekerja menyelesaikan 1 kanopi dalam 2 hari, maka 12 pekerja menyelesaikan 2 kanopi dalam waktu...**

This translates to:
"If 3 workers complete 1 canopy in 2 days, how long will 12 workers take to complete 2 canopies?"

To solve this, let's use the concept of work rates:

1. **Work rate for 3 workers**:
   - 3 workers complete 1 canopy in 2 days.
   - So, the work rate of 3 workers is \( \frac{1 \text{ canopy}}{2 \text{ days}} \).
   - Therefore, the work rate for 1 worker is \( \frac{1}{3} \times \frac{1 \text{ canopy}}{2 \text{ days}} = \frac{1 \text{ canopy}}{6 \text{ days}} \).

2. **Work rate for 12 workers**:
   - The work rate for 12 workers is 12 times the work rate of 1 worker.
   - \( 12 \times \frac{1 \text{ canopy}}{6 \text{ days}} = \frac{2 \text{ canopies}}{1 \text{ day}} \).

So, 12 workers can complete 2 canopies in **1 day**.

Thus, the correct answer is **A) 1 hari**.

Here are 5 related questions you might find useful:
1. How does the number of workers affect the time taken to complete a task?
2. If 6 workers were assigned the same task, how long would it take to complete 2 canopies?
3. What is the formula for calculating the work rate when the number of workers changes?
4. How would the solution change if 12 workers were assigned to complete 3 canopies?
5. How does the ratio of workers to time scale in this type of problem?

**Tip:** Always double-check the proportionality of workers to ensure the calculations remain consistent.
