PROCESSING OF RATTAN PLANT STEMS INTO RAW MATERIALS FOR THE FURNITURE INDUSTRY


The process of processing semi-finished rattan rods is the advanced processing of rattan from scratch into semi-finished goods that are ready to be used to make goods, furniture, or furnishings.
The stages of rattan processing are often also called merunti, the process of which is as follows:
  1. FRYING. Aims to reduce the water content and prevent fungal attacks. The way of frying is that pieces of rattan sticks are tied into a bundle, then put in a container that is shaped in such a way ( at the bottom there is a furnace to heat the mixture of diesel and coconut oil ). 
  2. SCRUBBING AND WASHING. Rattan that has been fried, drained for a few minutes, and then rubbed with a rag (coconut coir) mixed with sawdust and soil or sand, so that the remaining dirt, especially the sap that is still attached to the rattan skin can be removed, so that the rattan skin becomes clean and a color will be produced. brightly colored rattan and shiny.
  3. DRYING. Drying is done by exposing the rattan to the hot sun until it dries with a moisture content ranging from 15% – 19%. In Manau rattan and Semambu rattan, it shows that the natural drying time of the two types of rattan ranges from 22 days to 65.3 days. In this stage, rattan can already be used as a raw material with the term random rattan. However, most rattan types of rods | and cane is processed to be polished by removing the outer skin and uniform size.
  4. STRIPPING AND POLISHING. Peeling and polishing are generally carried out on rattan stalks in a dry state, using a polishing tool in the form of rotating scarf-shaped sandpaper to remove the rattan skin, so that the diameter and color become more uniform and even.
  5. PRESERVATION. The process of chemical or physical treatment of rattan which aims to increase its useful life of rattan is what happens when rattan is preserved. Besides functioning to prevent or minimize rattan damage due to destructive organisms, it also extends the life span of rattan. Preservatives used must be toxic to destructive organisms (on both wet rattan and dry rattan), permanent in rattan, safe for transportation and use, non-corrosive, available in large quantities, and cheap. Rattan powder attack can be identified because of the presence of fine flour used to grind the powder. These insects were most commonly found attacking rattan, including Dinoderus minutes Farb., Heterobostrychus aequalis Wat., and Minthea sp.
  6. GETTING STRAIGHT. This is done by bending the rattan on two pillars so that the rattan sticks are straight and easy to arrange | and tied in a bundle that is ready to be distributed.
