Jawaban:

The words provided (mengalir, membantu, mengaduk, menarik, membakar, menakar, mengadakan) are examples of words in Indonesian that begin with the prefix "MeN-". The prefix "MeN-" is used to indicate an action or process performed by the subject of the verb.

Based on the examples given, we can observe some rules that govern the use of the prefix "MeN-":

1. The prefix "MeN-" is attached to the root word, resulting in the formation of a new verb.

Examples: alir (flow) + MeN- = mengalir (to flow), bantu (help) + MeN- = membantu (to help), aduk (stir) + MeN- = mengaduk (to stir).

2. The prefix "MeN-" is followed by a vowel when attaching to a root word that ends with a consonant.

Examples: tarik (pull) + MeN- = menarik (to pull), bakar (burn) + MeN- = membakar (to burn).

3. The prefix "MeN-" is followed by a consonant when attaching to a root word that ends with a vowel.

Example: takar (measure) + MeN- = menakar (to measure).

4. The prefix "MeN-" changes to "Me-" when attaching to a root word that starts with "h" or "k".

Example: adakan (organize) + MeN- = mengadakan (to organize).

These rules provide guidance on the formation of words with the prefix "MeN-" in Indonesian. By applying these rules, we can create new verbs by attaching the prefix "MeN-" to the appropriate root words.
