These rice dumpling casings are made by weaving two coconut
ketupat
These rice dumpling casings are made by weaving two coconut leaves together. It is
usually made to celebrate the Muslim New Year, and it can be served with a variety
of dishes. The dumplings are made by adding rice to the casings and then boiling
them until the rice grains are compacted into a dumpling, after which the leaves are
cut away and the dumpling is cut into pieces. The woven case facilitates the cooking
of the rice, the draining of water from the freshly-cooked dumpling, and the transport and storage of the dumpling after cooking. The origin of the casing is thought
to be the sea-farers’ need for a portable, long-lasting source of food on board a vessel. The numerous ways of weaving a ketupat casing show how weaving craft in Indonesia is also present in cooking in addition to textiles and basket weaving.
The casings are partially filled with rice grains and then boiled for five hours. The
grains expand and compact inside the casing.
After boiling, the casing is cut and the rice is
sliced into cubes
There are numerous ways of weaving the casing, each resulting in a different shape:

Each casing shape is made by coiling one coconut palm around each hand, and then weaving the coils through each other.
The path that each strip takes:
Each casing geometry can also be made with a single surface:

Soft:
The casing geometries are all composed of a vocabulary of edges; those where the weaving intersects the edge at 90
degrees form a sharp transition between faces, and those that cross the edge at a different angle form a softer transition.

The idea of multiple simultaneous cycles is also present in the way of weaving a Ketupat casing,
and this forms my concept of the circulation of various paths of people within the building

The particular arrangement of program in this project allows for numerous very different uses and
purposes for each kind of person in the building. Some people, like the owner and the office tenant,
rarely need to access the same elements of the program, and their paths slide past each other.

The areas of program are easily separate, but the circulation of the different paths happens in a common space between between them.

Given the numerous paths in the building, I wanted to use the idea of woven coils to create an interior environment where the circulation paths of different kinds of people slide past each other along
the interior surfaces. The circulation forms an additional layer of weaving.
