Tata panggung mendukung interpretasi.

Dukung is the root word. In a normal active sentence, Indonesian usually uses the meN- form of a transitive verb, so dukung becomes mendukung.

The bare form dukung is more likely to appear:

• in a dictionary
• in commands, like Dukung tim ini!
• in some informal or reduced styles

So in a standard sentence like this, mendukung is the expected form.

It marks the verb as an active verb, especially when the subject is doing something to an object.

In this sentence:

• tata panggung does the action
• interpretasi receives the action

So mendukung is the normal active form.

Also, meN- changes shape depending on the first sound of the root. With dukung, it becomes men-, giving mendukung.

It follows a common Indonesian pattern: Subject + Verb + Object.

• Tata panggung = subject
• mendukung = verb
• interpretasi = object

So the basic structure is very similar to English.

Indonesian usually does not use articles the way English does. Nouns often appear without anything equivalent to a, an, or the, and the listener understands the meaning from context.

So interpretasi could mean:

• an interpretation
• the interpretation
• sometimes just interpretation in a general sense

The same idea applies to tata panggung.

Not specifically. Indonesian verbs usually do not change form for tense.

By itself, the sentence can be understood as:

• a general statement
• something true now
• something true in the relevant context

If you want to show time more clearly, Indonesian usually adds time words, for example:

• sedang for ongoing action
• sudah or telah for completed action
• akan for future action

It is a loanword, and it is very normal in Indonesian, especially in formal, academic, literary, or artistic contexts.

A more native-derived alternative is penafsiran, but interpretasi sounds perfectly natural here.

Yes. A natural passive version is:

Interpretasi didukung oleh tata panggung.

Here:

• didukung is the passive form
• oleh means by

This version puts the focus on interpretasi rather than on tata panggung.

Put tidak before the verb:

Tata panggung tidak mendukung interpretasi.

Use tidak to negate verbs and adjectives.
You would not normally use bukan here, because bukan is mainly used to negate nouns or noun phrases.

Yes, it sounds natural, but it is somewhat formal or analytical. It fits well in contexts like:

• theater discussion
• performance reviews
• classroom analysis
• academic writing about drama or staging

So it is a normal sentence, especially when talking seriously about how a performance works.
