Indonesian Kitchen
There are not a lot of kitchen tools that are specific to cooking Indonesian dishes, but there are indeed some specialized tools required to make a certain recipe, though many of these specialized tools can be hard to find outside Indonesia. The list of kitchen tools in this page are what I personally use in my kitchen, and most will be generic enough to be used to prepare many non Indonesian recipes as well.

We eat rice daily, for lunch and dinner, so a rice cooker always sits on my countertop.

The chopper and the 40 oz. bowl. are useful for spice paste. The pitcher is great for smoothies.

I make homemade tempeh with this proofer all the time. Also great for proofing bread and making yogurt.

I use this mixer to knead bread dough, whisk egg whites, whip heavy cream, or mix cake and cookie batter.
Bakeware

Fits inside my half-sheet pan for baking crispy bacon, chicken wings, and roast pork. A great cooling rack too.

This aluminum half-size angel food cake pan from Wilton is a must if you want to bake Asian chiffon cakes.

This is the cake pan I use to get that super straight edge lapis legit cake. It's also great for ogura, butter cake, and brownies.

This 8.5" x 4.5" x 2.75" pan is perfect for baking a standard 1-lb size loaf bread. It is also great for pound cakes.
Cookware

A set of multiclad cookware like this from Cuisinart should last you a life time. Mine has lasted for 5 years and still performs really well.

This is sold as a stir-fry pan, but I use this as my wok. It has a flat bottom, so much friendlier for those in the US.

With a 9.5-inch diameter and 4-inch deep steamer insert, it is large enough for almost all of my steaming needs. And I can use the bottom 5-quart pot as a soup pot.

Cast iron cookware will last you a life time and more when properly cared. And they are going to be your best non-stick pan ever.

For grilling on the stove, this cast iron grill pan is hard to beat. Burgers, steaks, and satays (Indonesian kebab!).
Kitchen Tools

One good chef knife is a must in any kitchen. This one has has been with me for more than 10 years. The sharpener keeps my blade sharp.

This ceramic rod sharpener is a must to properly hone and maintain the alignment of your blade.

A good non-slip cutting board is a must, and this one from OXO is lightweight yet does a really good job in my kitchen.

If you cook rice daily like me, you will love this rice washing bowl from Inomata. In a pinch, you can use it to wash vegetables and fruits too.

Every kitchen needs a set of mixing bowls. I have this set in my kitchen and they are the best mixing bowls I ever own.

I cannot function without my kitchen scale, especially for baking. This one easily converts between metric (gr) and imperial (lb/oz) units.

A zester like this is a must to zest citrus, grate garlic or ginger, and equally good for cheeses and chocolates.

I reach for these as much as I reach for my spatulas during cooking! And this one has been with me for more than 10 years.

These spatulas are heat resistant, flexible yet strong. I use these both for cooking and for stirring cake batter.

A fine mesh skimmer is the best tool to remove scums and impurities while cooking soup/broth. Works great to ladle out deep fried food too.

When deep-frying (hello, bakwan!), a spider skimmer is your best tool to scoop out deep-fried food. And you can place it over a mixing bowl to remove excess oil.

If you don't want to throw away your oil every time you deep fry, you will love this oil pot that comes with a strainer and a lid.

A good set of measuring cups is a must. This set from CIA is professional-grade and measures accurately! You won't ever need another set.

Just like the measuring cups, this set of measuring spoons from CIA is heavy duty, measures accurately, and should last you a life time.

The best tool to portion out smaller size Asian cookies (all those Chinese New Year cookies). Saves so much time and your hands will thank you.

This isn't a tool per say, but if you own a set of stainless steel pots and pans, there is nothing else that does a better job to clean them when nothing else works.
