Sesi bersama menghasilkan penyelesaian.

It follows the common Malay SVO pattern:

• Sesi bersama = subject
• menghasilkan = verb
• penyelesaian = object

So the sentence is built much like English: [subject] [verb] [object].

Bersama usually means with or together.

In this sentence, it most likely modifies sesi, so sesi bersama means something like:

• a joint session
• a shared session
• a session together

If you add a noun after it, the meaning becomes clearer, for example:

• sesi bersama guru = a session with the teacher
• sesi bersama keluarga = a session with the family

Without anything after bersama, the sentence leaves the participants understood from context.

Menghasilkan means to produce, to generate, or to yield.

It comes from hasil, which is related to result / outcome / product.
The pattern meng-...-kan forms a transitive verb, so menghasilkan normally takes an object:

• menghasilkan penyelesaian
• menghasilkan idea
• menghasilkan keputusan

So here the idea is that the session produced / yielded a solution.

Yes. They are closely related:

• hasil = result, outcome, product
• menghasilkan = to produce, to yield
• berhasil = to succeed / to be successful

A common learner mistake is confusing menghasilkan with berhasil. They are not the same:

• menghasilkan sesuatu = produces something
• berhasil = succeeds

Penyelesaian is a noun.

It comes from selesai, which means finished / complete.
With the noun-forming pattern peN-...-an, it becomes something like:

• completion
• settlement
• resolution
• solution

In this sentence, it means solution.

Malay usually does not use articles like English a/an/the.

So penyelesaian can mean:

• a solution
• the solution
• sometimes just solution in a general sense

The exact meaning depends on context. This is very normal in Malay.

Not necessarily.

Malay often leaves nouns bare, so penyelesaian by itself is fine.
If you say satu penyelesaian, you emphasize one solution more clearly.

Compare:

• menghasilkan penyelesaian = produced a/the solution
• menghasilkan satu penyelesaian = produced one solution

Both are grammatical.

You usually know from context, because Malay verbs do not change form for tense the way English verbs do.

So menghasilkan could mean:

• produces
• produced
• will produce

If Malay wants to be more explicit, it can add time markers such as:

• telah menghasilkan = has/had produced
• sedang menghasilkan = is producing
• akan menghasilkan = will produce

Without those, the sentence is neutral and context decides.

Yes, it is understandable and acceptable, especially in formal or organizational contexts.

That said, how natural it sounds depends on what exactly you mean:

• Sesi bersama ini menghasilkan penyelesaian. = This joint session produced a solution.
• Perbincangan bersama menghasilkan penyelesaian. = The joint discussion produced a solution.
• Sesi itu membawa kepada penyelesaian. = The session led to a solution.

So the original sentence is fine, but another wording might fit better depending on context.

In this sentence, it is most naturally read as part of the subject phrase sesi bersama.

So the meaning is closer to the joint session than to someone did something together.

If you wanted to clearly say that people acted together, Malay would often make that more explicit, for example:

• Mereka bersama-sama menghasilkan penyelesaian. = They together produced a solution.

So in your sentence, bersama is most naturally understood as describing the session, not the manner of the verb.

Yes. Depending on context, penyelesaian can also mean:

• resolution
• settlement
• completion

For example:

• in a problem-solving context: solution
• in a dispute context: settlement / resolution
• in a process context: completion

So it is a fairly broad noun, and context tells you which English word fits best.
