The ende HKBP book is an HKBP songbook (Huria Krsiten Batak Protestant) which contains HKBP hymns and praises in the Batak language.
This book was made by HKBP Pematang Siantar printing with many other options which are often used in churches.
In this increasingly modern era, we can use smartphones for positive things with ende books.
Now the Ende Book application can be used offline without using the internet, so worship becomes more comfortable and less disturbing.
The addition of non-existent logu also makes the collection of ende books and HKBP songbooks even more complete.
