“…The antibacterial activity of synthesized CuNPs was analyzed by following Kirby-Bauer (disk diffusion) assay in which bacteria species of Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 were used as gram-positive bacteria and gram-negative bacteria, respectively. The paper disk was immersed in each sample (Piper retrofractum extract, CuNPs, sterilized water and gentamicin as negative and positive controls, respectively) for 10 s. Then, they were placed into bacteria in the petri dish and incubated at 37 C for 2 x 24 h. The bacterial inhibition was measured through the inhibition zone (clear zone) around the paper disk [33].…”

The copper nanoparticles (CuNPs) have attracted much attention due to their application in diverse fields. The applications of CuNPs depend on their physical and chemical properties. This study presents the first report for the use of medicinal fruit extract of Piper retrofractum Vahl as an eco-friendly reagent in the synthesis of CuNPs using copper sulfate as a starting material. Piper retrofractum Vahl extract was employed as a bioreductor as well as a capping agent in the formation of CuNPs. The reaction process was assisted by sonication and stirring. The influences of extract concentration, pH, temperature, and reaction time on the size of CuNPs were studied in detail. The morphology and structure of synthesized CuNPs were characterized by UV-Vis, FT-IR, SEM-EDS, TEM, and XRD. The UV-Vis measurement showed the surface plasmon resonance (SPR) peak at 234-255 nm, whereas FTIR characteristic peaks of metal-oxygen (Cu-O) were confirmed in the range 550-570 cm À1 and Cu-O-H bonds led to bending absorptions in the region 870-880 cm À1. The synthesized CuNPs possess the spherical shapes and high content of copper (70.3%) as confirmed by SEM-EDS. From the TEM micrograph, it can be seen that the particle size distribution of CuNPs has a high uniformity with a size of 2-10 nm under the optimum condition. The crystalline nature of CuNPs as confirmed by XRD showed the crystallinity phase of 26.4%. The synthesized CuNPs have relatively good stability and could inhibit Escherichia coli and Staphylococcus aureus. The results proved that Piper retrofractum Vahl fruit extract could be applied for a greener synthesis of CuNPs with high uniformity of particle sizes.

“…Meanwhile, several researchers have reported the lignin content in other bamboo species from the Gigantochloa genus, including Gigantochloa apus with 22–25% [ 41 ] and Gigantochloa brang , Gigantochloa levis , Gigantochloa Scortechinii , and Gigantochloa wrayi —24%, 26%, 32%, and 26%, respectively [ 42 ]. In addition, Yusoff et al [ 43 ] reported that the lignin content of Gigantochloa albociliata bamboo ranged from 22–24%.…”

“…The low extractive content is favorable for use in the pulp and paper industry [ 49 ]. The determined extractive content of Gigantochloa pruriens bamboo was relatively lower compared to Gigantochloa apus [ 41 ], Gigantochloa brang , Gigantochloa levis , Gigantochloa scortechinii , and Gigantochloa wrayi [ 42 ]. However, it was slightly higher compared to Gigantochloa albociliata bamboo [ 43 ].…”

This study aimed to analyze the basic properties (chemical composition and physical and mechanical properties) of belangke bamboo (Gigantochloa pruriens) and its potential as a particleboard reinforcement material, aimed at increasing the mechanical properties of the boards. The chemical composition was determined by Fourier transform near infrared (NIR) analysis and X-ray diffraction (XRD) analysis. The physical and mechanical properties of bamboo were evaluated following the Japanese standard JIS A 5908 (2003) and the ISO 22157:2004 standard, respectively. The results showed that this bamboo had average lignin, holocellulose, and alpha-cellulose content of 29.78%, 65.13%, and 41.48%, respectively, with a degree of crystallinity of 33.54%. The physical properties of bamboo, including specific gravity, inner and outer diameter shrinkage, and linear shrinkage, were 0.59%, 2.18%, 2.26%, and 0.18%, respectively. Meanwhile, bamboo’s mechanical properties, including compressive strength, shear strength, and tensile strength, were 42.19 MPa, 7.63 MPa, and 163.8 MPa, respectively. Markedly, the addition of belangke bamboo strands as a reinforcing material (surface coating) in particleboards significantly improved the mechanical properties of the boards, increasing the modulus of elasticity (MOE) and bending strength (MOR) values of the fabricated composites by 16 and 3 times.

Kain kapas merupakan kain yang terbuat dari serat alam yang masih masif digunakan karena memiliki beberapa kelebihan. Akan tetapi, kain kapas juga memiliki kekurangan yaitu adanya kemungkinan menjadi tempat berkembangnya bakteri. Hal tersebut dapat diatasi dengan proses penyempurnaan antibakteri sehingga diperoleh kain yang memiliki ketahanan terhadap bakteri. Ekstrak daun bambu tali (Gigantochloa apus) dapat dimanfaatkan sebagai zat antibakteri karena mengandung senyawa fenol, alkaloid, dan flavonoid yang berpotensi untuk menghambat pertumbuhan bakteri. Penyempurnaan antibakteri dilakukan menggunakan larutan penyempurnaan yang terdiri dari ekstrak daun bambu tali, zat pengikat silang yang divariasikan yaitu asam sitrat dan binder GSL, dan katalis. Metode penyempurnaan yang digunakan yaitu metode pad-dry-cure dengan WPU sebesar 80% dan suhu pemanas-awetan yang divariasikan pada suhu 160°C dan 170°C. Pengujian yang dilakukan pada kain tersebut ialah pengujian aktivitas antibakteri terhadap bakteri E. coli dan pengujian sifat fisika kain meliputi kekuatan tarik dan mulur kain dan kekuatan sobek kain metode Elmendorf. Hasil penelitian menunjukkan bahwa ekstrak daun bambu tali dengan zat pengikat silang asam sitrat yang diaplikasikan pada kain kapas memiliki aktivitas antibakteri yang cukup dengan diameter zona hambat yang terbentuk sebesar 6 mm. Selain itu, penyempurnaan antibakteri ini tidak menyebabkan perubahan sifat fisika kain (kekuatan tarik, mulur kain, dan kekuatan sobek) yang signifikan secara statistika.
