Learn Hardcore Indonesian: Kami memperbarui jadwal tim setiap minggu.

kami = we (excluding the listener). That’s what the sentence uses: the listener is not part of the team doing the updates.
kita = we (including the listener). Use it if you’re talking to someone who is part of the group: Kita memperbarui jadwal tim setiap minggu.

Can I move setiap minggu to the front? Does the word order change the meaning?

Yes, both are natural and mean the same:

Setiap minggu, kami memperbarui jadwal tim.
Kami memperbarui jadwal tim setiap minggu. Fronting the time phrase adds emphasis to the frequency. Avoid splitting the object oddly; prefer end or front positions for time expressions.

Is memperbarui the best verb for “to update”? What about mengupdate or memutakhirkan?

memperbarui is the standard, general-purpose verb for “update/renew.”
memutakhirkan is more formal/technical (often for software/data).
mengupdate/nge-update/diupdate are common in speech/informal writing but are borrowings. In formal writing, prefer memperbarui/diperbarui or memutakhirkan/dimutakhirkan.

Why is it memperbarui and not memperbaharui?

Modern Indonesian prefers forms from baru (new), so memperbarui is the recommended standard. memperbaharui exists and is widely seen, but it’s treated as a less-preferred variant in Indonesian (while baharu is standard in Malay).

What does the prefix memper- add in memperbarui?

memper- often makes a causative verb “to make/become more X” from adjectives/nouns:

baru → memperbarui (to renew/update)

Can I use perbarui by itself?

Does jadwal tim mean “the team’s schedule” or “team schedules”? How do I show possession and plural?

Indonesian has no articles or obligatory plural marking. jadwal tim usually reads as “the team schedule.”
To make the possessor explicit: jadwal tim kami = our team’s schedule.
Plurals can be shown with duplication or context: jadwal-jadwal, tim-tim (often avoided unless needed).

Could I say jadwal kami instead of jadwal tim?

Yes, if “we” and the team are the same group. jadwal kami = our schedule. jadwal tim can refer to any team’s schedule; add kami if you mean your own team: jadwal tim kami.

Is tim the only word for “team”? What about regu or kelompok?

tim is the default across sports, work, and tech.
regu tends to mean “squad/shift/team unit” (e.g., factory/sports squads).
kelompok is “group” (not necessarily a team). Use tim here.

Where do I put the time phrase if I want “every Monday”?

Both are fine:

Setiap (hari) Senin, kami memperbarui jadwal tim.

How do I negate the sentence?

Use tidak to negate the verb:

Kami tidak memperbarui jadwal tim setiap minggu. Use bukan to negate nouns/pronouns, not verbs. You might add a contrast: Kami tidak … setiap minggu; kami … setiap bulan.

How do I say it in the passive?

Past/completed: Kami sudah memperbarui jadwal tim minggu lalu.
Future: Kami akan memperbarui jadwal tim minggu depan. You can also rely on time words alone: Kami memperbarui … minggu lalu/minggu depan.

Is there any difference between setiap minggu and tiap minggu? What about setiap pekan?

setiap minggu and tiap minggu are interchangeable; tiap is a bit more casual.

Should minggu be capitalized?

minggu (lowercase) = week.
Minggu (uppercase) = Sunday. Your sentence uses the lowercase meaning.
