Abstract
There are about 60 species of bamboo belonging to family gramineae found in Indonesia, which is one of them isPetungbamboo (Dendrocalamus asper). Bamboo has the potential to produce environmentally friendly engineering materials. The strength and durability of the material can be increased through the immersion process using chemical or natural solutions, such as sulphur water because it is known to contain carbon elements high enough to support strength increase. The research was started by making thick bamboo slats 1 mm thick, 250 mm long, 10 mm wide, and then woven in plain shapes of 250 mm × 250 mm, then dried at 110 °C for 60 min then immersed in sulfur water. For tensile test using the ASTM D638-02 standart, ASTM D790-02 bending test, ASTM D5942-96 impact test. The test results show the tensile strength increased 89.17 %, bending strength increased 59.90 % and impact strength increased 1.59 %. The highest value of the mechanical test results occurred in sample 1 AB3, while the lowest mechanical test value occurred in 1 TP sample. The microstructure of the 1 TP sample shows a pointed and smooth fracture shape while the sample 1 AB3 has an increasingly blunt fracture shape with fine threads.
Highlights
The growth rate of bamboo plants is fast enough so that their availability can be met quickly as well and can absorb carbon dioxide quickly so that it can reduce air pollution, in addition to the large enough carbon content in the wood can increase strength
From the results of this study, the lowest tensile strength was obtained in the sample of 0 d (1 TP), which was 84.04 MPa ± 0.87 MPa, while the highest tensile strength occurred in samples with immersion for 3 d (1 AB3) which was 159.02 MPa ± 0.47 MPa
Research on the tensile strength of Petung bamboo is said, the tensile strength of BRP is influenced by the type of bamboo and the variety of fibers
Summary
The growth rate of bamboo plants is fast enough so that their availability can be met quickly as well and can absorb carbon dioxide quickly so that it can reduce air pollution, in addition to the large enough carbon content in the wood can increase strength. The use of bamboo which has artistic value is a product of strips that are usually made of woven for various kinds of household items, walls, and furniture. Cellulose fibers contained in bamboo provide maximum flexural tensile strength and hardness in certain directions [2]. Lignin is a component of cell walls that is difficult to break down by organisms that destroy bamboo. Bamboo is one of the abundant and interesting natural fibers to be studied.
