Ketelitian mendukung kinerja.

Ketelitian is a noun. It means something like carefulness, accuracy, precision, or meticulousness, depending on context.

It comes from the base word teliti, which is usually an adjective meaning careful, thorough, or accurate.
Adding ke- ... -an often turns a quality into an abstract noun:

• teliti = careful, accurate
• ketelitian = carefulness, accuracy, precision

So in this sentence, ketelitian is the thing doing the action.

The base word is dukung, meaning support.
The form mendukung uses the prefix meN-, which commonly forms an active verb.

So:

• dukung = support / to support as a base form
• mendukung = supports / to support in an active sentence

Because the root starts with d, the prefix appears as men-, giving mendukung.

This is very common in Indonesian:

• dengar → mendengar
• dapat → mendapat
• dukung → mendukung

By itself, mendukung does not show tense the way English verbs do.

So depending on context, it could mean:

• supports
• is supporting
• does support

In a general statement like Ketelitian mendukung kinerja, the most natural English translation is usually Carefulness supports performance or Accuracy supports performance.

If you wanted past or future meaning in Indonesian, you would usually add time words or context, not change the verb form itself.

Kinerja is a noun meaning performance, especially in a work, business, organizational, or professional sense.

It can refer to:

• a person’s performance
• an employee’s performance
• a team’s performance
• a company’s performance
• overall work results

It is a fairly formal word. In many contexts, it sounds more professional than a very general word like kerja.

So Ketelitian mendukung kinerja sounds like a formal or semi-formal statement such as Accuracy supports performance.

Yes. This sentence uses the basic Subject–Verb–Object order:

• Ketelitian = subject
• mendukung = verb
• kinerja = object

So the structure is very similar to English:

• Carefulness supports performance

That makes this sentence quite straightforward for an English speaker.

Indonesian usually does not use articles like English does.

So:

• ketelitian can mean carefulness, the carefulness, or a kind of carefulness, depending on context
• kinerja can mean performance or the performance, depending on context

In this sentence, both nouns are being used in a general sense, so the English translation usually also sounds general:

• Carefulness supports performance
• Accuracy supports performance

Usually, no—not if you want the meaning Carefulness supports performance.

That is because teliti is generally an adjective, meaning careful, thorough, or accurate.
But here you need a noun as the subject of the sentence.

So:

• teliti = careful / accurate
• ketelitian = carefulness / accuracy

That is why ketelitian is the natural choice here.

It is natural, but it sounds somewhat formal or professional.

You might see or hear it in contexts like:

• workplace training
• business writing
• school materials
• management or HR discussions
• motivational slogans

It has the feel of a general principle, like saying:

• Accuracy supports performance
• Attention to detail improves performance

So yes, it is natural Indonesian, but not especially casual.

Yes, in some contexts that is a very good translation.

Possible translations include:

• carefulness
• accuracy
• precision
• meticulousness
• attention to detail

The best choice depends on the situation. For example:

• In quality control, accuracy or precision may fit best.
• In workplace advice, attention to detail may sound very natural.
• In a general statement, carefulness works well.

So the sentence could also be understood as Attention to detail supports performance.

A simple pronunciation guide is:

• ketelitian → keh-tee-lee-tee-an
• mendukung → men-doo-doong
• kinerja → kin-er-ja

A few helpful notes:

• ng in mendukung is like the ng in sing
• j in kinerja sounds like English j in job
• Indonesian stress is usually not as strong as in English, so the rhythm is fairly even

So the whole sentence sounds roughly like:

keh-tee-lee-tee-an men-doo-doong kin-er-ja
