“…This bamboo is taken from Kedalingan village, Tambakromo sub-district, Pati district, Central Java, in fresh condition and without any presservative or other chemical process. The selected apus bamboo is 80 mm in diameter with a thickness of 20 mm and has a compressive stress value of 60.66 kg/cm 2 [29]. So, from this value it can be calculated the maximum test load that bamboo can withstand namely: From the yield stress of the bamboo material and the maximum von Mises stress, the safety factor values can be calculated by equation (13).…”

The bamboo ladder is a traditional construction equipment that still survives on the market and is in demand, especially in rural communities such as Kedalingan village. However, bamboo stairs still do not consider the standard of stairs design. In addition, there are concerns that users of the ladder may experience injury due to falls because the ladder cannot withstand the load (unbalanced). This study aims to obtain the maximum load that can be held by bamboo ladders and the angle of the position of the safe ladder by considering the Indonesian people's anthropometric weight. Calculation results based on the principle of equilibrium show that with a maximum user weight of 89.25 kg, the ladder must be positioned with a minimum slope of 53,26o but less than 65.43o. In addition, a static loading simulation was carried out using SolidWorks 2019 on a bamboo ladder frame structure that was made referring to SNI 19 - 1956 – 1990. Simulation results show that the design of a bamboo ladder can withstand a maximum body weight of 89.25 kg with the maximum load value of bamboo holding is 98.93 kg.

“…The tensile strength of the composite with three layers of treated fiber is 18.07 MPa and 16.51 MPa for three layers of untreated fiber [11]. Treating the apus bamboo (gigantochloa apus) laminas by soaking them in methanol solution increases the tensile and flexure strength of laminated bamboo composites by about 10 % [12]. The results have shown that treatment of bamboo by NaOH or methanol solution will enhance the mechanical properties of bamboo composites.…”

This study aims to investigate the mechanical properties of bamboo apus (gigantochloa apus) as a natural reinforced composite material. Bamboo’s laminates of gigantochloa apus were used as reinforcement on the epoxy resin matrix. The parameters examined in this study are the configuration of lamina and compaction pressure. Laminate configuration varies in the number, thickness and direction of the lamina. Compaction pressures of 1.5 MPa, 2 MPa, and 2.5 MPa were used to fabricate the Laminated Bamboo Composites (LBCs). The stem of bamboo with a length of 400 mm was split to obtain bamboo lamina with a size of 400×20 mm. The thickness of bamboo lamina is varied between 1 mm, 1.5 mm, and 2 mm. The bamboo lamina is then preserved by watering it with a preservative solution in the form of 2.5 % sodium tetraborate solution and dried in an oven until the water content reaches 10 %. LBCs were made with a hand lay-up method. After the LBCs were molded, they were pressed with 3 variations of dies compaction 1.5 MPa, 2 MPa and 2.5 MPa. The tensile and bending tests were carried out on the LBCs. Tensile testing is performed in accordance with ASTM standard D3039 and the bending tests were conducted based on ASTM standard D7264. The results show that at each compaction pressure, the highest tensile and bending strength was achieved by LBCs with a thickness of 1 mm of bamboo lamina and 7 layers of bamboo laminates. The LBC with thinner bamboo lamina reinforcement and more layers has the highest tensile strength and bending strength, even it has a lower mass fraction. The LBCs with laminates oriented 0° exhibited greater tensile and bending strengths than the LBCs with laminates structured –45°/+45° and 0°/90°. The LBCs with the 0° laminates direction is matrix fracture followed by lamina fracture. In the 0°/90° direction, matrix fracture is followed by delamination in the 90° and 0° laminates direction. Delamination and lamina clefting were observed in LBCs with laminates oriented +45°/–45°.

“…Manik et al [73] mentioned that the kenaf fibres were treated with silane to strengthen the bonding between the fibre and the matrix by increasing cross-linking in the interface region and fibre surface area. Furthermore, the silane molecule has bi-functional groups that can react with fibre and matrix to form a siloxane bridge, which allows for a strong interaction between fibre and matrix and provides composite materials with superior mechanical performance.…”

This paper reviews the mechanical performance of bamboo fiber reinforced polymer composites (BFRP) for structural applications. Bamboo fibers are very promising reinforcements for polymer composites production due to their high aspect ratio, renewability, environmentally friendly, non-toxicity, cheap cost, non-abrasives, full biodegradability, and strong mechanical performances. Besides, bamboo has its own prospects and good potential to be used in biopolymer composites as an alternative for petroleum-based materials to be used in several advanced applications in the building and construction industry. For bamboo fibre to be reinforced with polymer, they must have good interfacial bond between the polymer, as better fiber and matrix interaction results in good interfacial adhesion between fiber/matrix and fewer voids in the composite. Several important factors to improve matrix-fiber bonding and enhance the mechanical properties of BFRP are by fibre treatment, hybridisation, lamination, and using coupling agent. Moreover, mechanical properties of BFRP are greatly influenced by few factors, such as type of fibre and matrix used, fibre-matrix adhesion, fibre dispersion, fibre orientation, composite manufacturing technique used, void content in composites, and porosity of composite. In order to better understand their reinforcing potential, the mechanical properties of this material is critically discussed in this review paper. In addition, the advantages of bamboo fibers as the reinforcing phase in polymer composites is highlighted in this review paper. Besides that, the bamboo-based products such as laminated bamboo lumber (LBL), glued-laminated bamboo (glubam), hybrid bamboo polymer composites, parallel bamboo strand lumber (PBSL), parallel strand bamboo (PSB), bamboo-oriented strand board (BOSB), and bamboo-scrimber have lately been developed and used in structural applications.
