Kami belum sempat membandingkan kedua bingkai itu.

Kami means we, but it is exclusive: it does not include the person being spoken to.

So Kami belum sempat membandingkan kedua bingkai itu means We haven’t had the chance to compare those two frames yet, where we excludes you.

If the speaker wanted to include the listener, they would usually use kita instead.

• kami = we, not including you
• kita = we, including you

Belum sempat means something like:

• haven’t had time to
• haven’t had the chance to
• haven’t gotten around to

It does not just mean not yet in a general sense. It specifically suggests that the action has not happened because there wasn’t enough opportunity or time.

So:

• Kami belum sempat membandingkan... = We haven’t had the chance to compare...

This is a very common question.

• belum sempat = haven’t had the chance yet
  This leaves open the possibility that it may still happen later.
• tidak sempat = didn’t have the chance / wasn’t able to in time
  This often sounds more final and tied to a particular situation.

Compare:

• Kami belum sempat membandingkan kedua bingkai itu.
  = We haven’t compared the two frames yet, but we still may.
• Kami tidak sempat membandingkan kedua bingkai itu.
  = We didn’t manage to compare the two frames.

Sempat refers to having enough time, opportunity, or a chance to do something.

Examples:

• Saya sempat makan. = I had time to eat.
• Saya tidak sempat makan. = I didn’t have time to eat.
• Kami belum sempat datang. = We haven’t had the chance to come yet.

So in your sentence, sempat is the key word showing that the issue is opportunity/time, not willingness.

The base/root is banding, which relates to comparison.

membandingkan is the usual verb form meaning to compare something.

This verb has:

• meN- prefix, which often forms active verbs
• -kan suffix, which often makes the verb take an object or gives it a causative/applicative sense

So:

• banding = comparison-related root
• membandingkan = to compare

In this sentence, membandingkan is the natural full verb because the speaker is comparing an object: kedua bingkai itu.

Indonesian often expresses compare directly with membandingkan plus the thing(s) being compared.

In this sentence:

• membandingkan kedua bingkai itu = compare those two frames

You may also see patterns like:

• membandingkan A dengan B = compare A with B

So both kinds of structure exist, but here the object already contains both items:

• kedua bingkai itu = those two frames / both of those frames

Because both items are packaged together in one noun phrase, no separate dengan is necessary.

Here kedua means the two or both.

So:

• kedua bingkai itu = those two frames / both of those frames

Important: kedua can also mean second in other contexts.

Examples:

• anak kedua = second child
• kedua bingkai itu = the two frames / both frames

Why the difference? It depends on the noun phrase and context.

In your sentence, kedua bingkai itu clearly refers to two items together, not the second frame.

Because of the structure.

• kedua bingkai itu = the two frames / both of those frames
• bingkai kedua itu would more naturally mean that second frame

Word order matters.

Compare:

• kedua bingkai itu = both/those two frames
• bingkai kedua itu = that second frame

So in your sentence, kedua comes before the noun and refers to the whole pair.

In Indonesian, demonstratives like ini and itu usually come after the noun phrase they modify.

So:

• bingkai itu = that frame
• kedua bingkai itu = those two frames

This is normal Indonesian word order.

English says:

• those two frames

Indonesian says, literally:

• two frames those

That is one of the most common word-order differences English speakers need to get used to.

Bingkai usually means frame, especially a physical frame such as:

• a picture frame
• a photo frame
• a glasses frame, in some contexts

In this sentence, it most naturally means frames as physical objects.

Depending on context, bingkai can also sometimes be used more abstractly, like framework, but the most likely meaning here is the ordinary concrete one: frames.

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

So:

• bingkai can mean frame or frames, depending on context

Here, the quantity is already clear because of kedua:

• kedua bingkai itu = the two frames / both of those frames

Indonesian can show plurality in several ways, for example:

• with numbers
• with words like beberapa or semua
• by reduplication in some cases

But when the meaning is already clear, no extra plural marking is needed.

Yes. It is an active sentence.

The subject is:

• Kami = we

The active verb is:

• membandingkan = compare

The object is:

• kedua bingkai itu = those two frames

So the structure is:

• Kami / belum sempat / membandingkan / kedua bingkai itu
• subject / aspect-opportunity phrase / verb / object

A passive version would look different, for example:

• Kedua bingkai itu belum sempat kami bandingkan. = Those two frames, we haven’t had the chance to compare yet.

Yes, that is possible, but the meaning changes slightly.

• Kami belum membandingkan kedua bingkai itu.
  = We have not compared those two frames yet.
• Kami belum sempat membandingkan kedua bingkai itu.
  = We have not had the chance/time to compare those two frames yet.

The version with sempat adds the idea of lack of opportunity or time. Without sempat, the sentence is more neutral and simply says the action has not happened yet.

A simple breakdown is:

• Kami = we
• belum sempat = have not yet had the chance
• membandingkan = to compare
• kedua bingkai itu = those two frames

So the pattern is:

Subject + belum sempat + verb + object

This is a very useful pattern in Indonesian. For example:

• Saya belum sempat makan. = I haven’t had time to eat yet.
• Dia belum sempat menelepon. = He/She hasn’t had the chance to call yet.
• Kami belum sempat membandingkan kedua bingkai itu. = We haven’t had the chance to compare those two frames yet.
