Beside Natural Rattan Furniture that we produce from synthetic rattan and water hyacinth, we also use natural rattan material. In order to maintain the quality and authenticity, natural rattan materials that we use .
The way of processing natural rattan raw materials, we do very thoroughly and professionally, of course all that we do just for the sake of satisfaction of each of our customers. While to produce the best natural rattan and quality, natural rattan must be boiled first, so the result of rattan will be more durable, more white and shiny.
Boiling process done for about 2 s / d 3 hours, then cooking water is mixed with kerosene as much as 15 liters with the number of rattan once boiled 150 stems.
After going through the first process of rattan, then boiled back for an hour so that it seeps, and then afterwards dried in the sun until it is completely dry.
this process can make this product can survive more strong, durable and also its quality is more assured.
Rattan used as raw material for industrial finished rattan furniture products is rattan that has been through processing. Processing activities are advanced work of round rattan into semi-finished goods and finished goods or ready to be used or sold.
Stages of natural rattan processing are as follows:
The purpose of frying is to lower the water content to dry quickly and also to prevent the occurrence of fungal attacks. The way the frying pan is the pieces of rattan are tied into a bundle, then put into a container that has been prepared a mixture of diesel with coconut oil.
2). Rubbing and Washing
After the rattan fried, drained a few minutes, then rubbed with a patchwork (coconut fiber) or burlap sack mixed with sawdust, so the rest of the dirt, especially the sap that is still attached to the rattan skin can be removed, so that the rattan skin to be clean and will produce rattan color which is bright and shiny.
After the rattan is washed and dried by drying the sun to dry with water content ranging from 15% – 19%. The results of Basri and Karnasudirja (1987) in Jasni et al. (2005) on rattan manau (Calamus manan Miq.) And rattan semambu (Calamus scipionum Burr.), Show that the natural drying time of both rattan species ranged from 22 days up to 65.3 days.
4). Peeling and polishing
Peeling and polishing is generally done on large rattan in dry conditions, the point is to remove the rattan skin, so that the diameter and color becomes more uniform and evenly distributed.
Smoking is done so that the color of rattan becomes yellow evenly and shiny. Fumigation is done on dry rattan that is still skinned (natural) Fogging is basically the process of oxidation of rattan with sulfur (SO2 gas) to rattan skin color to be whiter. The fuming time is about 12 hours and consumes about 7.5 kg of sulfur or 1.8 grams / rattan rod (Rachman 1990 in Jasni et al., 2005).
Rattan preservation is a process of chemical or physical treatment of rattan that aims to improve the life of rattan. In addition to the function of preventing or minimizing rattan damage due to the destructive oganisme, also extend the life of rattan.
The preservatives used must be toxic to destructive organisms in both wet and dry rattan, permanent in rattan, safe in transport and use, non-corrosive, available in bulk and inexpensive.
The bending or bending of rattan is carried out on large-diameter cane in accordance with its use. This method of bending is done by means of rattan is softened with steam hot water called steaming with cylindrical tube (steamer) so that the rattan tissue becomes soft so easily bengkokan.
The results of the study (Jasni 1992 in Jasni et al., 2005), show that craftsmen in the household industry, the bending process is done by heating directly the part to be bent on fire (kerosene stove and LPG gas). Then the part is bent with the help of the bending tool when the rattan is still hot. This method has some disadvantages that the process is slow and sometimes the heated part can burn, so black colored.

In addition, a small percentage of them use compressors, cutting machines, screws (shaft tools to insert nails) and taples. The production process is done in a house building. Building the house is divided into a place of production process, displaying finished products rattan and residence.
Besides the use of the tools needed in the production process, the availability of transportation means is a supporting factor for the success of the household business of rattan products.
