Nov 17, 2025 by Alex Braham 34 views

Hey guys! Ever wanted to impress your friends with your language skills or maybe just navigate a market in Indonesia like a pro? Well, learning to count is a super important first step. Today, we're diving deep into how to count to 30 in Indonesian. It might seem simple, but understanding the nuances will make you sound way more authentic. We'll break it down, give you some handy tips, and make sure you’re comfortable with these fundamental numbers. So, buckle up, and let’s get counting!

The Basics: Numbers 1-10

Alright, let's kick things off with the absolute basics – numbers one through ten. These are the building blocks for almost everything else in counting. Getting these down pat will make the rest of the journey a whole lot smoother, trust me. In Indonesian, these numbers are pretty straightforward and don't change much as you go higher. So, let's get them memorized:

1 is satu.
2 is dua.
3 is tiga.
4 is empat.
5 is lima.
6 is enam.
7 is tujuh.
8 is delapan.
9 is sembilan.
10 is sepuluh.

See? Not too shabby, right? The pronunciation is key here. Try saying them out loud. Satu sounds a bit like 'sah-too', dua like 'doo-ah', and tiga like 'tee-gah'. For sepuluh (ten), the 'p' sound is pretty clear, and the 'luh' at the end is soft. Practice these a few times. You can even use flashcards or an app to help drill them in. Remember, repetition is your best friend when learning new vocabulary, especially numbers.

Think about it: you’ll use these numbers constantly. Whether you’re asking for dua coffees, saying you’re tiga years old, or just counting down the days until your next vacation, these initial ten numbers are your go-to. Don’t underestimate their power! Mastering these early on will build your confidence and pave the way for learning the higher numbers, which often follow a predictable pattern based on these fundamentals. So, really focus on getting these dialed in before we move on. Guys, seriously, nail these, and you’re already way ahead of the game!

Counting from 11 to 20

Now that you’ve got the first ten down, let’s level up and tackle numbers eleven through twenty. This is where you’ll start to see a pattern emerge, which is awesome for memorization. The structure for these numbers is generally ‘belas’ added to the base number. Think of ‘belas’ as the Indonesian equivalent of adding '-teen' in English. It signifies that we’re moving past the initial ten into the teens.

Here’s how it works:

11 is sebelas. This one’s a bit of an exception. Instead of ‘satu belas’, it’s ‘sebelas’. The ‘se-’ prefix here is similar to how ‘one’ becomes ‘eleven’ in English. It’s just one of those quirks you have to remember.
12 is dua belas. Here, you take ‘dua’ (two) and add ‘belas’.
13 is tiga belas. Following the pattern, ‘tiga’ (three) plus ‘belas’.
14 is empat belas. You guessed it: ‘empat’ (four) plus ‘belas’.
15 is lima belas. ‘Lima’ (five) plus ‘belas’.
16 is enam belas. ‘Enam’ (six) plus ‘belas’.
17 is tujuh belas. ‘Tujuh’ (seven) plus ‘belas’.
18 is delapan belas. ‘Delapan’ (eight) plus ‘belas’.
19 is sembilan belas. ‘Sembilan’ (nine) plus ‘belas’.
20 is dua puluh. Now, for twenty, the pattern shifts slightly. We don’t use ‘belas’ anymore. Instead, we use ‘puluh’, which means 'tens'. So, ‘dua’ (two) multiplied by ten becomes ‘dua puluh’.

Isn't that cool? Once you get the hang of ‘belas’, the numbers from 12 to 19 are a breeze. Just remember that tricky ‘sebelas’ for eleven. And for twenty, you switch gears to ‘puluh’. Keep practicing saying these out loud. Dua belas sounds like 'doo-ah bell-ahs'. Tiga belas is 'tee-gah bell-ahs'. For dua puluh, it's 'doo-ah poo-loo'. The ‘p’ in ‘puluh’ is softer, almost like a ‘w’ sound sometimes, depending on the speaker.

This structure is super common in many languages, where you have a special word for 'teen' numbers and then a different system for tens. So, if you’ve learned another language before, this might feel familiar! Practice using these in sentences, even if it's just imaginary ones. Like, "Saya mau tiga belas apel" (I want thirteen apples). The more you use them, the more they’ll stick. We’re almost there, guys!

Moving On: Numbers 21-30

Alright, you've conquered the teens, and now we're on the home stretch to thirty! This part is actually really logical and builds directly on what you’ve just learned. For numbers twenty-one through twenty-nine, you simply combine the tens word with the unit word. Remember how twenty is ‘dua puluh’? We’ll use that as our base, and then add the numbers one through nine.

Let’s break it down:

21 is dua puluh satu. So, it’s literally ‘two tens, one’.
22 is dua puluh dua. ‘Two tens, two’.
23 is dua puluh tiga. ‘Two tens, three’.
24 is dua puluh empat. ‘Two tens, four’.
25 is dua puluh lima. ‘Two tens, five’.
26 is dua puluh enam. ‘Two tens, six’.
27 is dua puluh tujuh. ‘Two tens, seven’.
28 is dua puluh delapan. ‘Two tens, eight’.
29 is dua puluh sembilan. ‘Two tens, nine’.

See the pattern? It’s super intuitive. You just take the word for twenty (dua puluh) and tack on the numbers one through nine. This pattern continues for all the higher tens too, like thirty, forty, and so on. So, if you can count to ten and you know how to say twenty, you can essentially construct any number up to ninety-nine!

Now, for 30, we just extend the pattern. Since twenty is ‘dua puluh’ (two tens), thirty will be ‘tiga puluh’ (three tens).

30 is tiga puluh.

So, to recap the thirties:

31 would be tiga puluh satu.
32 would be tiga puluh dua.
...and so on, up to tiga puluh sembilan (39).

The pronunciation for these is pretty consistent. Dua puluh satu sounds like 'doo-ah poo-loo sah-too'. Just string them together. The slight pause between ‘dua puluh’ and the unit number helps with clarity. For tiga puluh, it's 'tee-gah poo-loo'. Keep practicing these. You can try counting objects around you in Indonesian. "Saya punya dua puluh lima buku" (I have twenty-five books). This makes learning practical and fun, guys!

This method of combining tens and units is fundamental. It's the same principle you'll use for counting much higher. So, by mastering 21-30, you've basically unlocked the key to counting way beyond this range. It’s all about recognizing the building blocks: the base numbers (1-9), the teen marker (‘belas’), and the tens marker (‘puluh’). You’re doing great!

Tips for Mastering Indonesian Numbers

Alright, my friends, we’ve covered the numbers from 1 to 30 in Indonesian. But just knowing the words isn’t enough, right? We need to make sure they stick. Learning a language, especially the nitty-gritty like numbers, requires a bit of strategy. So, here are some tried-and-true tips to help you really nail these Indonesian numbers and feel confident using them. Let’s make this knowledge permanent!

First off, pronunciation practice is non-negotiable. Indonesian pronunciation is generally quite phonetic, meaning words are pronounced as they are spelled, which is a huge plus. However, subtle differences matter. Pay close attention to the vowels and the emphasis. For instance, the difference between ‘tiga’ (three) and ‘tiga belas’ (thirteen) is the addition of ‘belas’, but getting the rhythm right is key. Try recording yourself and comparing it to native speakers online. Many language learning apps and websites have audio clips. Listen, repeat, and refine. Don't be shy – speaking out loud is the only way to improve!

Secondly, use spaced repetition systems (SRS). Apps like Anki or Quizlet are fantastic for this. Create flashcards with the Indonesian number on one side and the numeral on the other, or vice versa. The SRS algorithm will show you the cards you struggle with more frequently, optimizing your study time. It’s like having a personal tutor who knows exactly what you need to work on. Seriously, guys, these tools are game-changers for memorization.

Third, integrate numbers into your daily life. Make it a habit! Count things you see: ‘satu’ car, ‘dua’ birds, ‘tiga’ people. When you’re at the grocery store, try to mentally tally prices or quantities in Indonesian. If you’re watching a movie, pause and try to say the character’s age or the number of items they’re holding. The more you actively use the numbers in context, the more natural they become. This active recall is way more effective than passive reading.

Fourth, understand the structure. As we saw, Indonesian numbers have a logical build-up. Sepuluh (10), belas for teens (11-19, with sebelas as a special case), and puluh for tens (20, 30, etc.). Knowing these building blocks makes learning higher numbers exponentially easier. It’s not just rote memorization; it’s understanding the system. Once you get ‘puluh’, you can construct ‘dua puluh’, ‘tiga puluh’, and so on, just by adding the unit numbers. This architectural understanding of the language is invaluable.

Finally, find a language partner or tutor. Practicing with a real person adds a dynamic element that flashcards can't replicate. They can correct your pronunciation in real-time, offer cultural insights, and even create fun counting games. If a partner isn't feasible, even just listening to Indonesian music or podcasts where numbers are used can help tune your ear to the sounds and rhythms. Consistency is crucial, and making it fun will keep you motivated. You got this!

Conclusion: You've Got This!

So there you have it, guys! We’ve journeyed from satu all the way to tiga puluh in Indonesian. We’ve covered the fundamental numbers 1-10, navigated the slightly tricky teens from 11-20 (remember sebelas!), and learned the simple, logical structure for counting from 21-30 and beyond using ‘puluh’. You’ve seen how understanding the base numbers and the suffixes like ‘belas’ and ‘puluh’ unlocks a huge chunk of the Indonesian counting system. It's not just about memorizing a list; it's about understanding the patterns that make the language tick.

Remember those tips we discussed? Keep practicing pronunciation, use those SRS apps, integrate numbers into your daily life, really grasp the structure, and don't hesitate to find someone to practice with. The key takeaway here is that learning numbers is the gateway to so many other things in Indonesian – from ordering food and asking for prices to telling time and dates. These aren't just abstract words; they are practical tools that will significantly enhance your experience if you're traveling or interacting with Indonesian speakers.

Counting to 30 might seem like a small step, but it’s a foundational one. Each number you learn and successfully use builds your confidence and opens up more possibilities. So, keep practicing, stay curious, and have fun with it! You've put in the effort, and you should be proud of mastering this essential skill. Selamat belajar! (Happy learning!)”
