In Indonesia term "trekking" is not found on any relevant rating system used by Indonesians, but could be understood based on historical approach ( 1965,Jimmy Roberts ) from another country.On historical perspective, the based idea of trekking was to provide tents together with Sherpa, to guide and cook.
Nowadays the formula is well established; groups travel through the hills, walking for five to six hours each day with all their equipment carried by porters; good quality meals are provided along with warm sleeping bags and comfortable tents; the trekker carries a personal pack with camera, day clothing and snacks.
