“…Intermolecular interactions between the fibre and the polymer matrix might be responsible for this observed finding. The samples behaved similarly with those previously loaded with cassava starch film and then filled with cassava bagasse [48], the production of sugar palm fibre and starch [49], and the reinforcement of sugar palm starch composites by seaweed fibre [50]. It is known that biocomposites have lower densities and are suitable for lightweight and simple applications [51].…”

Biocomposite films were prepared using corn starch (CS), sorbitol as a plasticiser, and multi-scale kenaf fibre as reinforcing filler. The microstructure and the physical, tensile, and water barrier properties of corn starch reinforced with kenaf fibre were characterised and investigated. The biocomposite films were developed via the solution casting technique using 10 g of CS with 0 to 8% kenaf fibre as filler treated with 30% (w/w, starch basis) of sorbitol. The increased amount of kenaf fibre introduced contributed to improvements in film thickness, weight, and density. Conversely, slight reductions in the biocomposite films’ moisture content, water absorption, and solubility rating were 9.86–5.88%, 163.13–114.68%, and 38.98–25.17%, respectively. An X-ray diffraction (XRD) test revealed that the films were amorphous and that there was no effect on the crystallinity structure of films with kenaf fibre reinforcement. Fourier transform infrared (FT-IR) and rheological analysis indicated that kenaf fibre could weaken the molecular interaction of the film matrix. Field emission scanning electron microscope (FESEM) revealed the arrangement and uniform distribution of kenaf fibre at 0.2–0.8%. The incorporation of kenaf increased the tensile strength, Young’s modulus, and elongation at break until (6% wt) of fibre. With the kenaf fibre incorporation, the optimal tensile strength, Young’s modulus, and elongation at break of the films reached 17.74 MPa, 1324.74 MPa, and 48.79%, respectively. Overall, the introduction of kenaf fibre as filler enhanced the physical and mechanical properties of CS films.

“…Finding a bio-based material originating from a natural renewable source as a substitute for synthetic materials is one way to minimize the depletion of the earth's raw materials and the impact on the environment. In recent decades, natural fibers are attractive due to their nature, e.g., biodegradable, abundant availability, low cost, non-toxic, low density, eco-friendly, recyclable, and having a high strength-to-weight ratio (Ilyas et al 2018b;Jumaidin et al 2020;Kamaruddin et al 2020). The massive discrepancy between the existing demand and the cultivation rate of conventional fibers has prompted the emergence of new natural fibers that are chemically comprised of cellulose, hemicellulose, lignin, wax, ash, and other soluble substances (Senthamaraikannan and Kathiresan 2018).…”

A novel natural fiber derived from the Cymbopogan citratus plant was investigated for the first time. The characterization of the C. citratus fibers was conducted, and the chemical composition and physical, thermal, mechanical, crystallinity, and morphological characteristics were studied. The chemical composition analysis of Cymbopogan citratus fiber revealed that the suggested fiber was rich in cellulose contents (37.6%). The tensile test of C. citratus fiber demonstrated the fiber’s average tensile strength of 43.81 ± 15.27 MPa and modulus of elasticity of 1.046 ± 0.33 GPa. Further analysis with X-ray diffraction (XRD) confirmed that the crystallinity index of Cymbopogan citratus fiber was 35.2%, and the crystalline size was estimated as 4.28 nm. The Cymbopogan citratus fiber’s thermal stability was investigated via thermogravimetric analysis (TGA) and observed to be thermally stable (230 °C). A morphological investigation was employed on the fiber via a scanning electron microscope (SEM). The morphological study result exhibited that the fiber had a perforated and rough surface with the lumen in the center. Thus, the findings revealed that the Cymbopogan citratus fiber was a promising potential reinforcement for thermoplastic green composite applications.

“…The Dioscorea genus as climber can grow up to 20 m in height, depending on the height of the host trees (Kamaruddin et al 2020;Mat Lazim et al 2021). In Lombok, the genus D. alata grows by climbing on host trees up to 10 m. The host trees used for creeping are banten (Lannea coromandelica), sengon (Falcataria moluccana), gamal (Gliricidia sepium), eucalyptus (Melaleuca leucadendra), and moringa (Moringa oleifera).…”

Abstract. Indriyatno, Wijayanto N, Batubara I, Supriyanto. 2024. The diversity, ethnobotany and nutrient contents of Dioscorea for post-disaster food security in Lombok, Indonesia. Biodiversitas 25: 553-564. Earthquakes caused damage to infrastructure, houses, and roads in Lombok in 2018. After the earthquake, there was a shortage of food. Adaptation to address food shortage can be overcome by using local food sources, including those from the Dioscorea genus. The study aims to analyze the diversity and distribution, ethnobotany and nutrient contents of the Dioscorea genus in Lombok Island. Botanical explorations were conducted to identify the intraspecific varieties in the form of local types/names complemented with ethnobotanical study through structured interviews. The nutrient contents were determined using a standardized method in proximate analysis. The study found 12 local types of Dioscorea belonging to four species which are used by the community for adaptation after earthquake disaster, namely: D. bulbifera (kentang), D. bulbifera (engal), D. alata (uwi sawa), D. alata (lami), D. alata (uwi kuning ampenan), D. alata (uwi putih ampenan), D. alata (uwi ungu dara kunci), D. alata (uwi putih batu layar), D. alata (uwi ungu batu layar), D. esculenta var. apiculata (surak), D. esculenta var. spinosa (gembili) and D. pentaphylla (buyut). The highest diversity of Dioscorea is found in climate type C3 (8 local types), followed by climate type E (5 local types), climate type D4 (4 local types), climate type B2 (3 local types), and climate type C2 and D3 (1 local type). The local community utilizes the Dioscorea genus in several cultural events including when celebrating the Prophet Muhammad's birthday. The nutritional value of Dioscorea genus is high due to its carbohydrate content (66,09-76,96%), protein content (3.79-10.84%), fat content (1.70-9.58 %) and fiber content (0.32-6.81%). This study shows the potential of Dioscorea to be used as food sources that are cheap, easy to grow, and more adaptive to different environmental conditions to help post-earthquake communities.
