This is my update:

def submit():
    nama = Nama.get()
    tgl_lahir =  tgl_Lahir.get()
    alamat = Alamat.get()
    no_telp = No_telp.get()
    insert = (nama,tgl_lahir,alamat,no_telp)
    #connect to database
    db = pymysql.connect(db="db_petugas", host="localhost", passwd="", user="root")
    #prepare cursor
    cur = db.cursor()
    #insert into petugas table
    sql = "INSERT INTO petugas VALUES ("",%s, %s, %s, %s);"
    #execute sql code
    cur.execute(sql, insert)
    db.commit()
    db.close()
    #delete the entry
    Nama.delete(0, END)
    tgl_Lahir.delete(0, END)
    Alamat.delete(0, END)
    No_telp.delete(0, END)

This is error what i got: pymysql.err.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''Vanes', '1 June 2003', 'Grand Hill 23', '091293812030')' at line 1")

It is not safe to use concatenation with sql queries through python as it is vulnerable to sql injection. I recommend trying out to use placeholder(%s) and parametric substitution, like:

sql = "INSERT INTO petugas VALUES (NULL, %s, %s, %s);" #Using placeholders
# execute sql code
cur.execute(sql,insert) #substituting the tuple as a parameter
db.commit()
db.close()

Hope this cleared your error, do let me know if any doubts.

Cheers
