Learn Hardcore Indonesian: Pembaruan sistem telah membuat akun kami sinkron di setiap perangkat. - The system update has made our accounts synced on every device.

sudah for a more conversational tone: Pembaruan sistem sudah membuat…
Omit it when context already implies completion: Pembaruan sistem membuat… Meaning stays essentially the same; you just change formality/emphasis on completion.

Why say membuat … sinkron instead of using the verb menyinkronkan?

Both are fine, with a nuance difference:

membuat [object] [adjective] highlights the resulting state: the update “made our account synchronized.”
menyinkronkan [object] highlights the action of syncing: Pembaruan sistem telah menyinkronkan akun kami di setiap perangkat.

Should there be menjadi before sinkron (i.e., membuat … menjadi sinkron)?

Menjadi is optional here. You can say:

membuat akun kami sinkron (short, natural)
membuat akun kami menjadi sinkron (slightly more explicit/formal) Both are correct.

What part of speech is sinkron, and what are the related forms?

Sinkron is an adjective (“synchronized/in sync”). Related forms:

Verb (transitive): menyinkronkan (“to synchronize”)
Noun: sinkronisasi (“synchronization”)
Stative/result: tersinkron (“synchronized,” focusing on the resulting state)
Passive: disinkronkan (“be synchronized [by something]”)

Which is better here: sinkron, tersinkron, or tersinkronisasi?

sinkron is clear and concise for a state: akun kami sinkron.
tersinkron also emphasizes a resulting state and is common in tech UIs.
tersinkronisasi is heavier/less common in everyday prose. Prefer sinkron or tersinkron.

Is di setiap perangkat correct? How about pada setiap perangkat or di semua perangkat?

All are acceptable:

di setiap perangkat = “on each device” (very common)
pada setiap perangkat = a bit more formal
di semua perangkat = “on all devices” (collective rather than each one individually) Colloquial variant: di tiap perangkat.

What’s the difference between kami and kita?

kami = “we/our” excluding the listener.
kita = “we/our” including the listener. Use kami if the listener isn’t part of the group that owns the account(s).

Does akun kami mean one account or multiple accounts?

It’s context-dependent. Indonesian doesn’t mark plural by default. akun kami could be “our account” or “our accounts.” To be explicit:

Singular: satu akun kami / akun kami (with context)
Plural: semua akun kami / akun-akun kami (see next Q)

Is akun-akun kami natural?

It’s grammatical but often unnecessary. Reduplication can sound bookish. In practice, use semua akun kami or rely on context.

Can I make it passive: Akun kami telah disinkronkan …?

Yes: Akun kami telah disinkronkan di setiap perangkat. You can add the agent if needed: … oleh pembaruan sistem, though mentioning agents with oleh is often omitted when it’s obvious. Another common stative phrasing: Setelah pembaruan sistem, akun kami sudah tersinkron di setiap perangkat.

Where can telah be placed? Could I move it?

Typical placements:

Before the verb: Pembaruan sistem telah membuat… (most natural here)
Before a stative predicate: Akun kami telah/ sudah sinkron… Avoid: membuat akun kami telah sinkron (awkward), and telah rarely starts the sentence unless for emphasis in formal writing.

Is pembaruan sistem the best phrase? What about update sistem or a verb form?

pembaruan sistem = “a/the system update” (standard noun phrase; good in tech contexts)
update sistem = widely used in informal/tech marketing but more English-leaning
Verb: memperbarui sistem (“to update the system”) Note on correctness: modern standard prefers memperbarui / pembaruan; forms with “baharu” are older/less standard in Indonesia.

Why is there no “the/a” article?

Indonesian has no articles. Definiteness is inferred from context or added with itu (that/the): Pembaruan sistem itu… for “that/the specific system update.”

Can I say di semua perangkat instead of di setiap perangkat without changing the meaning?

You can; both imply comprehensive coverage. setiap highlights individual devices one by one, while semua treats them as a whole set. In many contexts the practical meaning overlaps.

How could I adjust register (more conversational vs. more formal)?

Conversational: Pembaruan sistem sudah nyinkronin akun kami di semua perangkat.
Neutral (original): Pembaruan sistem telah membuat akun kami sinkron di setiap perangkat.
More formal: Pembaruan sistem telah menyinkronkan akun kami pada setiap perangkat.

Is perangkat the right word for “device”? Any alternatives?

Perangkat is standard and broad. Alternatives:

gawai (common in Indonesia, often for gadgets/phones)
peranti (more formal/technical, more common in Malay usage) In general Indonesian tech context, perangkat is the safest choice.
