Architecture

The kariwari is one of the traditional Papuan houses, more precisely the traditional house of the Tobati-Enggros people who live around Yotefa Bay and Lake Sentani near Jayapura. Unlike other forms of Papuan traditional houses, such as the round honai, the kariwari is usually constructed in the shape of an octagonal pyramid. Kariwari are usually made of, bamboo, iron wood and forest sago leaves. The Kariwari house consists of two floors and three rooms or three rooms, each with different functions. The kariwari is not like a honai that can be lived in by anyone, it cannot even be the residence of a tribal chief – unlike the honai which has political and legal functions. The kariwari is more specific as a place of education and worship, therefore the position of the Kariwari in the community of the Tobati-Enggros people is considered a sacred and holy place. Like traditional houses in general, the kariwari also has a design that is full of decorative details that make it unique, of course, the decorations are related to Papuan culture. especially from the Tobati-Enggros. The decorations found in the kariwari are usually in the form of works of art, among others; paintings, carvings and also sculptures. Apart from being decorated with works of art, the kariwari is also decorated with various weapons, such as; bow and arrow. There are also some skeletons of prey animals, usually in the form of wild boar fangs, kangaroo skeletons, turtle or turtle shells, birds-of-paradise, and so on.

Rumsram is the traditional house of the Biak Numfor people on the northern coast of Papua. This house was originally intended for men, while women were prohibited from entering or approaching it. Its function is similar to the kariwari, namely as a place for activities in teaching and educating men who are starting to be teenagers, in seeking life experiences. The building is square with a roof in the shape of an upside down boat because of the background of the Biak Numfor tribe who work as sailors. The materials used are bark for floors, split and chopped water bamboo for walls, while the roof is made of dried sago leaves. The walls are made of sago leaves. The original rumsram wall only had a few windows and its position was at the front and back. A rumsram usually has a height of approximately 6–8 m and is divided into two parts, differentiated by floor levels. The first floor is open and without walls. Only the building columns were visible. In this place, men are educated to learn sculpting, shielding, boat building, and war techniques. In a traditional ceremony called Wor Kapanaknik, which in the Biak language means "to shave a child's hair", a traditional ritual is usually carried out when boys are 6–8 years old. The age when a child is considered to be able to think and the child has started to get education in the search for life experiences, as well as how to become a strong and responsible man as the head of the family later. The children would then enter a rumsram, hence the rite of passage is also called rumsram, because the ritual are carried out in the rumsram.
