In fact, often the health insurance itself also offers 
medical tourism to patients as an alternative. In fact, 
it is also colored by the presence of tour packages that 
include medical care, travel and hospitality and 
sightseeing services. In the context of promotion, the 
points of sale that are carried out are very unique, 
such as cost effectiveness and its combination with 
tourist attractions, often even packed with traditional 
therapies and treatment methods. The slogan offered 
is also very interesting namely "First World treatment 
at Third World prices." The success of the promotion 
certainly cannot be separated from the synergy of the 
sellers of tourism products. Remarkably, India is able 
to coordinate it well, for example Kerala as a medical 
tourism destination, and AIMS as a provider of 
medical treatment. 
While the results of a study on health tourism in 
Indonesia was carried out by Sumaryati (2015), 
entitled Study of Oxygen Health Tourism Potential in 
Gili Iyang, because Gili Iyang Island is famous for 
having high oxygen levels. High oxygen is used as a 
basis for development and development in Gili Iyang, 
as a health tourism destination. Checking oxygen 
levels on Gili Iyang is carried out by several agencies. 
The results of measurements in the showed that 
oxygen levels on Gili Iyang were in normal 
conditions at 20.9%. The fresh air in Gili Gili is not 
because of high oxygen levels, but because the air is 
clean of pollutants. If there are measurements from 
other agencies that show the presence of spots with 
high oxygen levels above 22%, in fact high levels of 
oxygen need to be watched out because high oxygen 
levels can cause oxygen poisoning called hyperoxia 
and potentially cause devastating fires. The results of 
this study are still based on the potential and basic 
studies of oxygen levels in Gili Iyang. 
Another study on health tourism in Indonesia was 
conducted by Rosalina et al (2015), on Opening the 
Door to the Development of Medical Tourism in Bali, 
in this study it was mentioned that Bali as one of the 
top destinations in Indonesia, had also tried to prepare 
an international hospital. Until now, there are at least 
3 hospitals that are internationally recognized, 
namely the Sanglah Central General Hospital, Bali 
International Medical Center which also cooperates 
with Courtyard Marriot Bali and Bali Royal Hospital. 
Sanglah Hospital claimed to have prepared 
quality and service with the focus of Medical Tourism 
at the Amerta International Wing as asuperior 
program. Some of the steps taken by RSUP include 
standardization of service quality, competency 
certification for health workers and increased 
hospitality so that they can provide maximum service. 
In addition, the Bali Royal Hospital even conducted a 
promotion to Germany in the ITB (Internationale 
Tourismus-Börse) Berlin in 2013 and 2014 in 
collaboration with the Bali Provincial Tourism 
Office. At the event, BROS had the opportunity to 
launch a prime package specifically made to be 
marketed in the medical tourism program. There are 
four packages offered, such as: medical check-up 
packages, IVF, plastic surgery and orthopedy 
packages. In addition to having several international 
hospitals, Bali also has health workers who support 
the implementation of medical tourism in the future. 
Expert doctors and medical and non-medical 
personnel owned by Bali are relatively adequate. In 
2013 there were 366 expert doctors and 2,438 medical 
and non-medical personnel. This situation is 
supported by the superiority of Bali which has a 
variety of traditional treatments that can be combined 
after medical treatment takes place. 
3 RESULT AND DISCUSSION 
Karo is a nation that has existed for hundreds or even 
thousands of years and inhabits several regions in 
North Sumatra Province, Indonesia, and at the same 
time makes one of the names of the Regency in the 
Karo Plateau, namely Karo District. Some of the 
areas inhabited by the Karo people in North Sumatra 
are called Tanah Karo, where these areas include 
Langkat Regency, Deli Serdang Regency, Medan 
City, Karo Regency, Dairi Regency, and also to 
Southeast Aceh. 
Karo community is a society that has a high 
cultural civilization, and this can be seen from the 
advances in technology and science that have been 
developing for thousands of years in this area. As 
proof of this in the Karo area, it can be found in the 
presence of Siwaluh Jabu or also often called the Karo 
Traditional House, which is a large and tall house, and 
equipped with technology to withstand earthquake 
shocks. 
In addition to the existence of a traditional house, 
the Karo community has also been familiar with the 
culture of writing since hundreds of years ago. That 
writing in general can still be seen on sheets of ulim 
bark called Pustaka Laklak, the writing with the 
character of Karo. Through the Laklak Library we can 
find various writings, namely about prophecy 
(katika), turi-turin (story), mangmang/tabas (mantra), 
the book of abortion, lamentation (sayings), we 
mayan (martial arts), ndung- ndungun (pantun), as 
well as medicinal herbs. Specifically regarding the 
existence of writings on the book of medicine, as well 
as the ingredients of medicines that can be found in
