Analisis Sifat Mekanik Lentur Papan Laminasi Kombinasi Bambu Petung dan Bambu Ater

Abstract

Kemajuan teknologi memunculkan alternatif bahan bangunan pengganti kayu, seperti bambu laminasi. Laminasi bambu menggunakan kombinasi dua jenis bambu yaitu bambu petung dan bambu ater. Bambu petung memiliki kuat lentur lebih besar dibandingkan bambu ater dapat meningkatkan nilai MOR dan MOE. Penelitian ini bertujuan untuk mengetahui kuat lentur, pengaruh susunan lapisan laminasi, pengaruh penambahan bambu petung pada laminasi bambu ater dari laminasi kombinasi dua jenis bambu. Pengujian kuat lentur papan laminasi berukuran 55 cm x 10 cm x 2 cm yang mengacu pada ASTM D1037-06a dengan beban terpusat ditengah bentang. Papan laminasi terdiri dari 3 variasi susunan, setiap variasi ada 4 lapisan dengan tebal bilah 0,5 cm. Variasi A terdiri dari susunan bambu ater-ater-ater-ater, variasi B terdiri dari bambu petung-ater-petung-ater, variasi C terdiri dari bambu petung-petung-ater-ater. Hasil pengujian kuat lentur papan laminasi didapat nilai rata-rata Modulus of Rupture (MOR) variasi A sebesar 89,462 MPa, variasi B sebesar 96,778 MPa, dan variasi C sebesar 79,173 MPa. Nilai rata-rata Modulus of Elasticity (MOE) variasi A sebesar 13256,830 MPa, variasi B sebesar 14856,552 MPa, dan variasi C sebesar 12981,294 MPa. Susunan variasi B petung-ater-petung-ater dapat meningkatkan nilai Modulus of Rupture dan Modulus of Elasticity.

“…However, compared to the study by Sulistianingsih et al [29], the moisture content value of nine bamboo has an average value of 12.9%. Belatrix et al [28] reported Ater bamboo laminated boards have an average moisture content value of 12.58%, where both values are higher than the moisture content values in this study.…”

“…Sulistianingsih et al [27] reported that the moisture content value of Andong bamboo laminated boards has an average value of 11.1%. Belatrix et al [28] reported that the moisture content of laminated boards made from a combination of Betung and Ater bamboo had an average value of 12.12%. In addition, Iswanto et al [11] regarding the manufacture of belangke bamboo-based particleboard, which also has a lower moisture content value ranging from 6.56% -7.96%.…”

“…Ater bamboo (Gigantochloa atter Kurz.) or what is often called ater bamboo has bright green to dark green stems and a diameter of about 5 -10 cm, a segment length of about 40 -50 cm with a stem height of up to 22 m (Belatrix, et al, 2022). -Malvaceae family with hibiscus or new plant species (Hibiscus tiliaceus L.) where the tree trunks are used as rope, considering that hibiscus trees function as reinforcement in composites because hibiscus skin fiber has a continuous fiber structure and a strong natural weave (Nurudin, 2011), and, hibiscus wood fiber is known to contain low lignin (Aulya, et al, 2020).…”
