I have a 120 V 60 Hz 1500 W coffee maker, but the power outlets at where I live are 240 V. What can I use to allow safe usage of this coffee maker?

No. It will not be safe to just plug it in and use it.
Most likely, if it is well built and well maintained, it will just blow a fuse. Ideally in the plug or the coffee maker itself, but possibly in your house instead. If it is not well built and well maintained, it may end up burning, catching fire, sparking, or exploding.
You need an adapter with a transformer. Not just an adapter that changes one plug configuration to another, but one that changes voltage too.
Note also, your power supply is probably 50hz instead of 60. It is unlikely that a coffee maker is sensitive to that change, but it may be if it relies on the frequency for its internal timer or clock. In that case, you will need an adapter that changes voltage and frequency. By that point it will probably be more expensive than the coffee maker itself. You may be better off buying a new coffee maker suitable for your local market.
You can buy a 1500W autotransformer, which will probably be the size of a small loaf of bread and cost 2x the price of a cheap 240V coffeemaker. If you have a $2000 espressomaker, go for it.
This is a 1000W one, which might not be enough wattage:
I’ve used a smaller version to run e.g. a record player. Make sure you wire it correctly (neutral is common).
If the coffeemaker is purely resistive (has no electronics or clock), you can use a diode (rated 10A 250V or more) to convert 240V AC to half-wave-rectified 120V DC. That will work for a heater or incandescent lamp but probably damage anything else. If you see a 240/120V converter that is suspiciously much smaller and cheaper than a transformer, that’s what it is.
Probably not the safest answer, but it might just work 🙂
If it’s a very simple coffee maker with just a heating element and a bi-metal switch, it will probably work.
Where I live we have 380v in some houses, and 240 in others, with normal power outlets always being 240v.
I hooked up normal simple coffee maker (240v 50Hz) to the 380v lines, and it worked perfectly. The heating element heats up much more quickly, and the bi-metal will switch it off more quickly. Bonus is that your coffee maker runs faster 😀
I would however never run this setup in my kitchen unattended. In my workshop when I’m working, where it doesn’t matter if it goes up in flames, I don’t mind.
There is no cheap and safe way. There are small “
power converters” that claim to do that, but they are either simple diodes that will wreck many appliances, or they’re like light dimmers that often do the same.
The only safe way is with a transformer, and a 1500W transformer will weigh about 25 pounds and cost you about $150.
I would just buy a local coffee-maker at a thrift shop for $3. If the culture there supports thrift shops, many don’t.
