It should look something like this:
int angka_test = 10;
int a;
while (1) {
output = output_start + ((output_end - output_start) * (angka_test - input_start)) / (input_end - input_start);
a = angka_test;
__HAL_TIM_SET_AUTORELOAD(&htim2, output);
}

why 'a' if i see from watch is 0, but angka_test=100, help me
Perhaps provide a screenshot of how you're seeing this, and a detailed description of how you get there?
Note that Keil is a 3rd-party products - nothing to do with ST - so you really need to be asking Keil about specific issues with their tool:

Two things to note:
- Optimisation: in the code shown, you never use the value of a - so it's likely to have been optimised away;
- Understand how Keil updates its "Watched" values - maybe what you're seeing is just "out of date", because the display hasn't updated?
A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
