Responsible repairer:
Drill a hole on the kemek part, screw a long bolt on the hole. Heat up the entire area(ofcourse need to pull out everything inside the car), then pull the bolt so the kemek part will come back out. Once everything is in place, proceed with welding to patch up the cracked area. Finally, grind off extra welded surface, apply fiber patch on the surface. Sand it off until surface is smooth. Apply primer, spray paint. Oven bake dry.

Irresponsible repairer:
Cut the entire rosak area out. Get a piece of metal plate, T weld it on. Grind off extra area. Apply patch, sand off surface. Apply primer, spray paint.

DIY:
Go bai saisket, double sided tape. Drill 2 extra holes on both front/back fender to further secure the new saisket. Gaodim

Btw, looks like 1st garden

Long process? That is small matter, can be done within same day if you send in the morning, probably can collect car in the evening. However though, if claim insurance, usually you're going to have to wait for

1) Claim registration(1 week waiting period usually, despite bank negara say 2 days)
2) Adjuster survey(Another 1 week usually, despite bank negara say 1 day after claim registration)
3) Police report(within 2 weeks from accident, consider you reported on the same day after accident, and u did went to workshop for claim registration).
4) Repair time(usually another week and above, despite PIAM ady ruled 1 week maximum regardless how bad the condition is)

So, basically motor insurance claim, the limit of days to be spent on workshop shall not exceed 21 working days(by law la).  I'm sorry, you're referring to what as long process? If you don't wish to claim insurance, I will still recommend you go report police. God knows what the bike rider will go report say you came out of junction suddenly, as a result causing him crash in to your car FYI, bodily injury can sue upon 3rd party on the DRIVER instead of insurance company. So, if I'm the rider, I'll 1st go and look for a company talk to the HR personnel, get the person to hire me as a senior officer pay me 10k a month. Then go hospital talk to a doctor, to prescribe me 3 months not fit for work. After that, I'll get a loya who willing to take up my case, sue against you to pay me 3 months salary 30k nia, then 5k for the "hired" company, 5k for the doctor, 5k for the loya. I take 15k to repair my bike lar
If 10 years ago, you'll see a blue color KE20 going side ways on that road 4~5am. That's when I finish work from Pengakalan going through Menglembu, hitting Taman Mas and using that road go home. You're lucky only a bike hit you. Can't imagine if you kena hit by my KE20

From the angle you're turning, u should be heading to GP foodcourt direction. Keep driving straight, u will pass through new indian temple on the left, keep going straight at the cross junction. After that, u will pass by 1st garden industrial area. After industrial area is a small river, cross that river immediately on the left is mamak(teh ais damn nice), on the right under tree got say (HI TECH ENTERPRISE), that's my regular magician when ayam in Ipoh. Once u turn right, immediately 1st lot on your left is a makat/paint shop - Assuming you're not going to claim your insurance. However, if you're going to claim insurance, please call your insurance company to find out which panel workshop is more reliable and whether it's near to your house.
