ORA-00903 : invalid table name when make trigger after insert Oracle - oracle

Question

Error screenshot
I'm trying to create trigger :
Create or Replace trigger poin_member
After Insert on dtl_poin
For Each Row
Begin
Update into tb_member set total_poin = total_poin + NEW.tambahan poin
Where id_member=NEW.id_member;
End;
To add up every data insert on tambahan_poin that have the same id_member and insert the sum results into total_poin but error invalid table name. even though the table name entered is correct.
what's the solution?

Oracle points you to error position. It says:
LINE/COL ERROR
-------- -------------------------------------
2/1 PL/SQL: SQL Statement ignored
2/8 PL/SQL: ORA-00903: invalid table name
Line #2:
Update into tb_member
--------
12345678

error is here. Obviously, invalid syntax. You can't use INTO here
So, yes - you should pay attention to what Oracle says and do something about it.
Quite a few errors. I'm creating sample tables, just to make trigger compile. Read comments within code.
SQL> CREATE TABLE dtl_poin
2 (
3 id_member NUMBER,
4 tambahan_poin NUMBER --> in your trigger, you used "NEW.tambahan poin" which is invalid
5 -- as there can't be any space in column name (unless enclosed
6 -- into double quotes)
7 );
Table created.
SQL> CREATE TABLE tb_member
2 (
3 id_member NUMBER,
4 total_poin NUMBER
5 );
Table created.
SQL>
Trigger:
SQL> CREATE OR REPLACE TRIGGER poin_member
2 AFTER INSERT
3 ON dtl_poin
4 FOR EACH ROW
5 BEGIN
6 -- UPDATE INTO tb_member --> wrong syntax; INTO can't be used here
7 UPDATE tb_member
8 SET total_poin = total_poin + :NEW.tambahan_poin
9 WHERE id_member = :NEW.id_member;
10 END;
11 /
Trigger created.
Testing:
SQL> INSERT INTO tb_member (id_member, total_poin)
2 VALUES (1, 25);
1 row created.
SQL> INSERT INTO dtl_poin (id_member, tambahan_poin)
2 VALUES (1, 100);
1 row created.
SQL> SELECT * FROM dtl_poin;
ID_MEMBER TAMBAHAN_POIN
---------- -------------
1 100
SQL> SELECT * FROM tb_member;
ID_MEMBER TOTAL_POIN
---------- ----------
1 125 --> good; 100 was added to 25 and the result is now 125
