Thank you for your reply.
I also tried to make the wire connectivity in Baofeng mic and speaker according to the post in this threads :?/g/BITX20/topic/4554574

The PTT switch in Baofeng work perfectly, but not for the speaker and mic. I will try to make the modification like you've said.

But what about the RX system? It still not receiving any ham radio signal. I tried to follow the troubleshooting that Asshar Farhan made in?
Here is what I've got

C107 (C13 in my schematic) makes noise when it's touched with cable.
C33 (C6) is also make noise
C31 (C9) is also make noise, but not very loud.
C53 (C5) I didn't hear any noise at all.?
C21 (C24) I didn't hear any noise at all.?

I also didn't hear any noise if the cable touched the antenna connector.

I made my own BPF and LPF because I want to make 8.456 MHz frequency as the center frequency.

Here is the schematic. To tell you the truth I didn't buy the kit from Asshar Farhan. I built in from scratch, like from the schematic, the PCB layout, and bought all the component by myself. I come from Indonesia. And this is for my final project. Still learning and this is my first time building a radio

Thank you very much for helping me
