Sehubungan dengan aktiviti perniagaan itu, kami memilih kod industri.

Yes, sehubungan dengan is fairly formal. In this sentence, it means something like in relation to, in connection with, or regarding.

It is common in formal writing, administration, business, and official communication. In everyday conversation, a speaker might more naturally say:

• berkaitan dengan = related to
• tentang = about
• mengenai = regarding

So sehubungan dengan aktiviti perniagaan itu sounds more formal than casual speech.

This fronted phrase gives the context first. Malay often places a contextual phrase at the beginning of the sentence, especially in formal writing.

So the structure is:

• Sehubungan dengan aktiviti perniagaan itu = in relation to that business activity
• kami memilih kod industri = we chose the industry code

This is similar to English patterns like:

• Regarding that business activity, we chose the industry code.
• In connection with that business activity, we chose the industry code.

Starting with the context makes the sentence sound organized and formal.

Itu here points to a specific business activity, like that in English.

So:

• aktiviti perniagaan = business activity / business activities
• aktiviti perniagaan itu = that business activity / those business activities

In Malay, itu often comes after the noun phrase, unlike English, where that usually comes before:

• English: that business activity
• Malay: aktiviti perniagaan itu

This is a very common word order in Malay.

Malay has two common words for we:

• kami = we, excluding the listener
• kita = we, including the listener

So kami memilih kod industri means the speaker’s group chose the code, but the listener is not part of that group.

That is why kami is used here. If the listener were included in the decision-making group, kita would be more appropriate.

Memilih is a verb meaning to choose or to select.

It comes from the root pilih = choose/select.

The prefix meN- changes the root into an active verb:

• pilih = choose
• memilih = to choose / choosing

This is a very common verb pattern in Malay. The verb is transitive here, meaning it takes an object:

• kami memilih kod industri
• we chose the industry code

The object is kod industri.

Malay does not have articles like English a, an, and the.

So kod industri can mean:

• industry code
• an industry code
• the industry code

The exact meaning depends on context.

If the speaker wants to make it clearly specific, Malay may use context, word order, or words like itu:

• kod industri itu = that industry code / the industry code

But often Malay simply leaves the noun without an article, and the listener understands it from the situation.

Malay often uses one noun to modify another noun directly. This is a very common structure.

So:

• kod industri = industry code
• literally, something like code industry

Here, industri functions as a modifier describing what kind of code it is.

This noun + noun pattern is normal in Malay, for example:

• kad kredit = credit card
• pasar raya = supermarket
• aktiviti perniagaan = business activity

A form like kod perindustrian might be possible in some contexts, but kod industri is the more straightforward and natural wording for an industry classification code.

Perniagaan means business, trade, or commercial enterprise, depending on context.

Aktiviti perniagaan is more specific: it means business activity or business activities. It focuses on what the business does rather than just the business as an entity.

Compare:

• perniagaan itu = that business
• aktiviti perniagaan itu = that business activity / those business activities

In official forms or classification systems, aktiviti perniagaan is common because the code is often chosen based on the actual activity being carried out.

Yes. Sehubungan is related to hubung, which has the basic idea of connection or relation.

You may also see related forms such as:

• hubung = connect, relation
• berhubung = to be in contact / to be connected
• hubungan = relationship, connection
• sehubungan dengan = in connection with, regarding

You do not need to break down sehubungan every time you use it, but knowing the root idea of connection helps you remember the phrase.

Yes. Depending on the tone you want, you could use:

• berkaitan dengan aktiviti perniagaan itu = related to that business activity
• mengenai aktiviti perniagaan itu = regarding that business activity
• tentang aktiviti perniagaan itu = about that business activity

The differences are mostly about style and register:

• sehubungan dengan = formal, official
• berkaitan dengan = neutral, common
• mengenai = formal-neutral
• tentang = common, everyday

For official or bureaucratic language, sehubungan dengan fits very well.

Malay nouns usually do not have to show singular/plural the way English does. So aktiviti can mean:

• activity
• activities

The same applies to kod industri in some contexts.

Whether it is singular or plural depends on context. In this sentence, aktiviti perniagaan itu could refer to one specific business activity or a set of business activities already understood by the reader.

If a speaker really wants to mark plurality clearly, reduplication is one option:

• aktiviti-aktiviti perniagaan = business activities

But in real usage, Malay often leaves number unmarked unless it matters.

Because Malay commonly links nouns directly in compound noun phrases.

So:

• aktiviti perniagaan = business activity
• kod industri = industry code

English often uses adjective-like modifiers or possessive-style relationships, but Malay frequently just places the modifying noun after the main noun.

This pattern is extremely important to get used to. It is one of the most natural ways Malay builds meaning.

Yes. A less formal version might be:

• Berkaitan dengan aktiviti perniagaan itu, kami pilih kod industri.

Or even:

• Untuk aktiviti perniagaan itu, kami pilih kod industri.

Changes here:

• berkaitan dengan is less formal than sehubungan dengan
• pilih is more conversational than memilih

The original sentence sounds like something you might see in a form, letter, report, or official explanation. The alternative versions sound more neutral or conversational.
