Tolok ukur ini objektif.

In Indonesian, you often do not need a verb like to be in simple present-tense statements.

So:

• Tolok ukur ini objektif = This benchmark is objective

The structure is simply:

• tolok ukur ini = this benchmark
• objektif = objective

This kind of sentence is very common in Indonesian, especially when the predicate is an adjective or a noun.

In Indonesian, demonstratives like ini (this) and itu (that) usually come after the noun.

So:

• tolok ukur ini = this benchmark
• buku ini = this book
• rumah itu = that house

This is different from English, where this comes before the noun.

Tolok ukur means benchmark, standard, criterion, or measure, depending on context.

It is a fixed expression in Indonesian. In many contexts, it refers to something used as a basis for judging or comparing.

Examples:

• Ini menjadi tolok ukur keberhasilan. = This becomes a benchmark for success.
• Tolok ukur kinerja perusahaan = A benchmark/measure of company performance

So in your sentence, tolok ukur ini objektif means that the benchmark or standard being discussed is objective.

It is written as two words: tolok ukur.

Even though it functions as a single idea, it is normally spelled separately. This is common in Indonesian with certain fixed expressions.

So write:

• tolok ukur

Not:

• tolokukur

Yes. In this sentence, objektif is an adjective meaning objective.

It describes tolok ukur ini.

So the sentence pattern is:

• Subject: tolok ukur ini
• Predicate adjective: objektif

Indonesian adjectives do not change form for singular/plural, gender, or person.

Normally, no. That would sound unnatural in standard Indonesian.

The word adalah is usually used to connect a subject with a noun phrase, not an adjective.

Good:

• Dia adalah guru. = He/She is a teacher.

Less natural / generally avoided:

• Dia adalah pintar.

So with an adjective like objektif, the natural sentence is:

• Tolok ukur ini objektif.

If you want a slightly more explicit version, you could say:

• Tolok ukur ini bersifat objektif. = This benchmark is objective in nature.

That sounds a bit more formal.

No. Here objektif means objective, not objectively.

It is describing the noun phrase tolok ukur ini.

If you wanted objectively as an adverb, Indonesian would usually use something like:

• secara objektif = objectively

Example:

• Masalah ini harus dinilai secara objektif. = This issue must be assessed objectively.

So in your sentence, objektif is definitely an adjective.

It sounds neutral to somewhat formal.

• tolok ukur is a common expression, but it often appears in formal writing, academic writing, business discussion, or analytical speech.
• objektif is also common in formal and semi-formal contexts.

In everyday casual conversation, people might sometimes use alternatives like:

• patokan
• standar

But tolok ukur is perfectly normal and widely understood.

Yes, depending on the nuance.

Possible alternatives include:

• patokan = guideline, yardstick, reference point
• standar = standard
• ukuran = measure

For example:

• Patokan ini objektif.
• Standar ini objektif.

But they are not always exact matches. Tolok ukur often has the sense of a benchmark or a basis for evaluation.

So tolok ukur is a good choice when discussing assessment, comparison, or criteria.

Indonesian nouns usually do not show singular or plural by themselves.

So tolok ukur could theoretically refer to one benchmark or benchmarks in the right context. But here, because of ini and the natural reading of the sentence, it is most likely understood as this benchmark or this standard.

If you wanted to make plurality clearer, Indonesian might use context, numbers, or reduplication:

• tolok-tolok ukur ini is not natural
• More natural would be something like tolok ukur ini semua depending on context, though usually people simply rely on context

In this sentence, the most natural reading is singular.

The pattern is:

• Noun phrase + adjective

More specifically:

• Tolok ukur ini = subject
• objektif = predicate adjective

This is a very common Indonesian structure.

Similar examples:

• Mobil itu mahal. = That car is expensive.
• Anak ini pintar. = This child is smart.
• Keputusan itu adil. = That decision is fair.

So Tolok ukur ini objektif follows a very standard Indonesian pattern.

It is usually pronounced roughly like:

• ob-jek-tif

A rough English-friendly guide would be:

• ob-JEK-tif

A few pronunciation notes:

• j in Indonesian sounds like English j in job
• e in jek is like the e in bed
• the final f is pronounced clearly

Also, Indonesian stress is usually not as strong or dramatic as in English.

Not freely.

The natural order is:

• Tolok ukur ini objektif.

If you change the order, the meaning may change or the sentence may become unnatural.

For example:

• Ini tolok ukur objektif. = more like This is an objective benchmark
  That is a different structure and emphasis.

So if you want exactly This benchmark is objective, the best version is:

• Tolok ukur ini objektif.
