Profesionalisme mengurangi bias.

Mengurangi comes from the root kurang, which means less, lacking, or not enough.

In this sentence, it becomes a verb:

• kurang = less / insufficient
• mengurangi = to reduce / to lessen

This is a very common Indonesian pattern:

• meN- prefix often makes an active verb
• -i can help form a transitive verb, often one that affects something

So mengurangi bias literally means something like to make bias less.

Also note the spelling change:

• root: kurang
• with meN-: the initial k drops
• so it becomes mengurangi, not mengkurangi

Because mengurangi is a transitive verb, meaning it takes a direct object.

Here:

• Profesionalisme = the subject
• mengurangi = reduces
• bias = the thing being reduced

So the structure is:

• X mengurangi Y = X reduces Y

By contrast, berkurang means to decrease or to become less, and it usually does not take a direct object in the same way.

Compare:

• Bias berkurang. = Bias decreases / becomes less.
• Profesionalisme mengurangi bias. = Professionalism reduces bias.

So mengurangi is the correct choice when you want to say that one thing causes another thing to become less.

Yes, basically. Profesionalisme is a borrowed word and means professionalism.

It is used in formal or semi-formal Indonesian, especially in writing, education, workplace discussions, ethics, management, and public speaking.

It is built like this:

• profesional = professional
• -isme = -ism

So:

• profesionalisme = professionalism

This kind of word formation is very common in Indonesian:

• nasionalisme = nationalism
• optimisme = optimism
• realisme = realism

Usually yes. Bias in Indonesian generally means bias, partiality, or systematic slant in judgment, reporting, research, or decision-making.

It is especially common in:

• psychology
• statistics
• media
• politics
• workplace or social discussions

So in this sentence, bias means the same general idea as in English: unfair or uneven judgment.

One thing to watch out for is pronunciation. In Indonesian, bias is usually pronounced more like bee-as (two syllables), not like the English word bias.

Because Indonesian does not use articles the way English does.

In English, you often need:

• a
• an
• the

In Indonesian, those words are usually not translated directly.

So:

• Profesionalisme mengurangi bias can mean
  Professionalism reduces bias
  or, depending on context,
  The professionalism reduces bias

Usually the broader, general meaning is understood from context. In this sentence, it sounds like a general statement:

• Professionalism reduces bias.

Yes. This sentence follows the very common Indonesian pattern:

• Subject + Verb + Object

So:

• Profesionalisme = subject
• mengurangi = verb
• bias = object

This is the most straightforward and neutral word order in Indonesian, especially in simple statements.

Yes, that is grammatically possible, but it is less natural in most everyday contexts.

• Profesionalisme mengurangi bias. = active voice
• Bias dikurangi oleh profesionalisme. = passive voice

The passive version means:

• Bias is reduced by professionalism

It is correct, but the active version is usually simpler and more natural unless you specifically want to focus on bias instead of profesionalisme.

Yes, it sounds fairly formal and abstract.

All three words feel appropriate in:

• essays
• presentations
• workplace ethics discussions
• academic writing
• policy or management contexts

In casual conversation, people might still understand it, but they might choose simpler wording depending on the context.

For example, a more conversational idea might be expressed with a longer sentence, such as explaining that being professional helps people be more fair.

A rough English-friendly pronunciation is:

• Profesionalisme: pro-fe-si-o-na-lis-me
• mengurangi: meng-u-rang-i
• bias: bi-as

A few useful notes:

• Indonesian pronunciation is usually quite regular.
• bias is two syllables: bi-as
• mengurangi has the ng sound as in sing
• The e in me- is often a weak vowel, like the a in about

A rough full pronunciation:

• pro-fe-si-o-na-lis-me meng-u-rang-i bi-as

Yes. Depending on context, mengurangi can be translated as:

• reduce
• decrease
• lessen
• diminish

In your sentence:

• Profesionalisme mengurangi bias

the best natural English translation is probably:

• Professionalism reduces bias

But other translations may also fit in the right context:

• Professionalism lessens bias
• Professionalism diminishes bias

Because Indonesian verbs usually do not change form for tense.

The verb mengurangi can refer to present, past, or future depending on context.

So by itself:

• Profesionalisme mengurangi bias is most naturally understood as a general present statement: Professionalism reduces bias.

If you wanted to make time clearer, Indonesian would usually add a time word:

• telah mengurangi = has reduced / reduced
• sedang mengurangi = is reducing
• akan mengurangi = will reduce

But without those markers, the sentence is still perfectly normal.

Sometimes, but they are not always identical.

• profesionalisme usually refers to professionalism as an attitude, standard, or code of conduct
• profesionalitas can refer more to professional quality or degree of being professional

In many contexts they overlap, but profesionalisme is the more natural choice for a general statement like this:

• Profesionalisme mengurangi bias.

It sounds like a statement about values, behavior, and standards, which fits profesionalisme very well.
