Aku membandingkan dua kamera analog.

Both aku and saya mean I, but they differ in tone.

• aku is more casual, personal, and commonly used in everyday speech, especially with friends, family, or in informal writing.
• saya is more neutral and polite, and is often preferred in formal situations or when speaking to people you do not know well.

So Aku membandingkan dua kamera analog sounds natural in an informal context. In a more formal context, you could say:

• Saya membandingkan dua kamera analog.

Membandingkan comes from the root banding, which is related to comparing.

It is built like this:

• banding = compare / comparison-related root
• meN- → becomes mem- here
• -kan = a suffix that often makes the verb transitive or gives it the sense of doing something to an object

So:

• membandingkan = to compare something

In this sentence, the object is dua kamera analog, so the verb needs a form that works naturally with a direct object.

In standard Indonesian, membandingkan is the normal verb for to compare something.

• banding by itself is just the root, not the usual standalone verb in this meaning.
• membanding is generally not the standard form for to compare in modern Indonesian.

The -kan suffix is important here because it helps form the verb used with an object:

• Aku membandingkan dua kamera analog = I compare/am comparing two analog cameras.

So if you want to say that someone compares one thing with another, membandingkan is the expected choice.

Indonesian does not use a separate verb like am/is/are in the same way English does for many sentences.

So:

• Aku membandingkan dua kamera analog can mean:
  • I compare two analog cameras
  • I am comparing two analog cameras

The exact time reference usually comes from context or from time words such as:

• sekarang = now
• sedang = in the middle of doing something / currently

For example:

• Aku sedang membandingkan dua kamera analog. = I am comparing two analog cameras.

Without sedang, the sentence can still naturally describe a present action.

In Indonesian, numbers normally come before the noun they count.

So:

• dua kamera analog = two analog cameras

This is the normal order:

• dua buku = two books
• tiga rumah besar = three big houses
• empat kamera analog = four analog cameras

So the structure here is completely regular:

• dua
  • kamera
    • analog

Indonesian nouns usually do not change form for plural the way English nouns do.

So:

• kamera can mean camera or cameras, depending on context.
• dua kamera already clearly means two cameras, so no plural ending is needed.

Compare:

• satu kamera = one camera
• dua kamera = two cameras

Sometimes Indonesian can show plurality by reduplication:

• kamera-kamera = cameras

But in this sentence, that is unnecessary because dua already tells you there are two.

In Indonesian, adjectives usually come after the noun they describe.

So:

• kamera analog = analog camera
• literally: camera analog

This is very common:

• rumah besar = big house
• mobil baru = new car
• buku menarik = interesting book

So dua kamera analog follows the usual Indonesian order:

• number + noun + adjective

Analog is a borrowed word, and it is commonly used in Indonesian, especially in technology and photography contexts.

So kamera analog is a normal phrase meaning an analog camera, as opposed to something like:

• kamera digital = digital camera

Indonesian contains many loanwords, and this is one example that looks very similar to English.

Yes, sometimes Indonesian can omit the subject if it is already clear from context. For example, in conversation:

• Sedang membandingkan dua kamera analog. = (I’m) comparing two analog cameras.

However, when giving a full standalone sentence, including aku makes it clear and complete:

• Aku membandingkan dua kamera analog.

So omission is possible, but the full sentence with aku is the safest and clearest form for learners.

By itself, membandingkan does not usually clearly mark past tense. Indonesian verbs do not change form for tense the way English verbs do.

So the sentence can often be interpreted from context as present or general:

• I compare
• I am comparing

If you want to make it clearly past, Indonesian often adds a time word, for example:

• Aku tadi membandingkan dua kamera analog. = I compared two analog cameras earlier.
• Kemarin aku membandingkan dua kamera analog. = Yesterday I compared two analog cameras.

So the verb form stays the same, and time is usually shown through context or extra words.

Yes. Adding itu makes the noun phrase more specific.

• dua kamera analog = two analog cameras
• dua kamera analog itu = those two analog cameras / the two analog cameras

So:

• Aku membandingkan dua kamera analog. = I am comparing two analog cameras.
• Aku membandingkan dua kamera analog itu. = I am comparing those two analog cameras.

The version without itu is less specific and sounds more general.

No, that word order is not natural in standard Indonesian.

The normal order is:

• dua kamera analog

not:

• kamera analog dua

In Indonesian, the number usually comes before the noun, and the adjective usually comes after the noun:

• dua
  • kamera
    • analog

So Aku membandingkan dua kamera analog is the correct structure.

Yes, it is natural and grammatically correct.

It has a very standard structure:

• Aku = subject
• membandingkan = transitive verb
• dua kamera analog = object

A native speaker would understand it easily. If you wanted to emphasize that the action is happening right now, you could also say:

• Aku sedang membandingkan dua kamera analog.

But the original sentence is already perfectly natural.
