“…Dari jurnal terdahulu dapat diketahui bahwa kekuatan bahan komposit meningkat dengan seiring dengan bertambahnya komposisi dari resin dalam bahan komposit [5]. Dimana peran resin sendiri adalah membaerikan kohesi dan kekuatan pada komposit yang memungkin mempertahankan bentuk dan integritas strukturalnya [6]. Kemudian untuk karakter dari bahan komposit didapatkan kesimpulan bahwa semakin tinggi komposisi serbuk kayu pada bahan komposit maka kecenderungan bahan komposit yang dihasilkan adalah tidak tembus pandang dan semakin ringan [7].…”

PT. Berdikari Meubel Nusantara is a furniture manufacturing company that uses three types of wood, namely mahogany, pine, and teak. Handling and processing sawdust waste is a challenge that needs to be overcome effectively so that the waste can become a product that has added value. The value-added product in question is souvenir craft. The utilization of coarse sawdust can be mixed with epoxy resin to form composite materials, which can be used as the basic material for souvenir crafts. It is known that the strength of composite materials increases with the increasing composition of the resin in composite materials, and the character of composite materials If the composition of sawdust is higher, the resulting composite material will be opaque and lighter. Then the manufacture of composite materials will use a ratio of 1:1. Regional attributes, cultural elements, innovation in form, design, and ease of application are important factors to consider when designing a product for souvenirs. The collected data is needed to be translated into the interpretation of product requirements to be used in making the Objective Tree and Morphological Diagrams. Evaluation of alternative product designs is carried out by considering the minimum risks. Abstrak PT. Berdikari Meubel Nusantara merupakan perusahaan manufaktur furniture yang menggunakan 3 jenis kayu yakni mahoni, pinus, dan jati. Penanganan dan pengolahan limbah serbuk kayu menjadi sebuah tantangan yang perlu diatasi secara efektif, sehingga limbah tersebut dapat menjadi produk yang memiliki nilai tambah. Produk bernilai tambah yang dimaksud adalah kerajinan souvenir. Pemanfaatan serbuk kayu kasar dapat dicampur dengan resin epoxy untuk membentuk bahan komposit digunakan sebagai bahan dasar kerajinan souvenir. Diketahui bahwa kekuatan bahan komposit meningkat seiring dengan bertambahnya komposisi dari resin dalam bahan komposit dan karakter dari bahan kompositnya. Jika komposisi serbuk kayu semakin tinggi maka bahan komposit yang dihasilkan cenderung tidak tembus pandang dan semakin ringan. Maka pembuatan bahan komposit digunakan perbandingan 1 : 1. Hal yang perlu diperhatikan dalam perancangan souvenir adalah atribut daerah, unsur budaya, inovasi dalam bentuk, desain, dan mudah dalam pengaplikasiannya. Dari data yang terkumpul diterjemahkan ke dalam interpretasi kebutuhan produk yang akan digunakan dalam pembuatan Pohon Tujuan serta Morfologi Diagram. Evaluasi alternatif desain produk dilakukan dengan mempertimbangkan resiko yang paling minimal

The global increase in demand for natural resources raises urgent concerns about environmental sustainability. The transition to renewable natural materials, such as lignocellulosic fibers, is a promising strategy to mitigate environmental impacts. These fibers, derived from renewable sources, have low density and unique mechanical properties, making them attractive alternatives to synthetic materials. Composites reinforced by natural fibers have gained prominence, providing mechanical resistance and reducing costs. Waste such as corn stalk, abundant throughout the world, has been studied as reinforcement in composites. The use of these fibers not only offers environmental advantages, such as biodegradability and lower energy demand in production, but also contributes to the promotion of sustainable practices. Additionally, research shows that waste corn residue can be turned into valuable resources. Studies conducted with corn stalk husk revealed superior performance in composites, indicating its potential as a reinforcing material. Other research involving sliced culm demonstrated promising results, highlighting the economic viability and possibility of developing a new low-density engineering material. Therefore, the use of natural fibers, such as those from corn stalks, in composites represents not only an environmentally friendly solution, but also an opportunity for innovation in the production of sustainable materials, which will be the reason for this review.

The effect of resin modification through the incorporation of the biomass waste in the form of seashell powder on the mechanical properties of basalt fiber–reinforced epoxy/seashell composites is examined through experimental investigations. The resin modification is done through the addition of seashell powder in 5, 10, 15, and 20 wt.%. The modified resin is then reinforced with basalt fiber mat and the required laminate is obtained through compression molding technique. The specimens required for various mechanical tests, such as flexural, tensile, inter laminar shear (ILSS), and the impact strengths, are cut from the laminate as per the standard ASTM dimensions. The mechanical test results indicate that through the addition of the seashell filler additional toughening mechanisms are introduced which improves the strength of the composite laminate. The improvement in the flexural modulus value for all the laminates made from modified resin indicates the ability of the laminate to deflect the applied load effectively and efficiently. The optimum wt.% addition of seashell filler into the resin is found to be 5% for flexural, ILSS, and impact strength while for tensile strength it was observed to be 10%. The addition of higher wt.% loading of seashell filler into the resin has rendered the resin too thick and viscous with minimum flowability. Thus, there is a reduced wettability of the modified resin with the basalt fibers due to which the strength of the laminates reduces. The SEM analysis indicates widespread delamination for higher wt.% addition of the seashell filler into the resin.
