Unable to block list websites inside file using squid

my squid.conf
acl deny_websites dstdomain "/etc/squid/urlblock.txt"
http_access deny deny_websites

my /etc/squid/urlblock.txt
.facebook.com
.detik.com

I stop the squid first
service squid stop
pkill -9 squid

then restart
service squid restart
sudo usr/sbin/squid

My other configuration in case it may be the cause of problem

http_access allow all
....
visible_hostname ProxySquid
