		abstract={The existence of the PMI Blood Transfusion Unit is recognized to have provided many benefits and assistance to patients / sick sufferers who desperately need blood. Thousands or even millions of people have been saved thanks to the help of the PMI Blood Transfusion Unit. Likewise with health services, almost every PMI in various regions has a polyclinic. PMI really needs blood for hospitals and many people also
want to donate blood for those in need, but often these donors don't have much time if they have to come and register to become donors. What's more, you have to wait in
line and fill out the registration form for your personal history and it will take a lot of time. To overcome this problem, registration is needed that can be done online and
can be done anywhere, besides that, not only registering, donors can also donate blood at their homes without having to queue and leave the house. By using themethod havershine , PMI officers can see the distance where the blood donor wants to donate blood}
