“…Alat dekortikator serat dapat beragam dalam desain dan kompleksitasnya, tetapi umumnya mereka melibatkan proses pengupasan atau pemisahan secara mekanis. Teknologi yang digunakan dalam alat ini terus berkembang untuk meningkatkan efisiensi dan kualitas serat yang dihasilkan [5][6][7] [8]. Laporan Penelitian ini disusun sebagai bahan infomasi pengetahuan teknologi dekortikator untuk memperoleh serat dari batangnya.…”

Serat alam memiliki keunggulan dibandingkan degan serat sintetis karena sifatnya yang dapat terurai dan berkelanjutan. Permasalahan yang ditemui dalam serat alam adalah proses ekstraksi atau pemisahan dari kulit dan serat. Penelitian ini bertujuan untuk merancang alat dekortikator yang berfungsi untuk memisahkan kulit dan serat alam sehingga dapat digunakan sebagai bahan penguat komposit. Prosedur dalam desain mesin dekortikator dilakukan dengan mengumpulkan data awal dan kebutuhan tentang mesin dekortikator, menentukan teknologi dan mekanisme mesin dekortikator yang efektif, perancangan konsep dan mekanisme, dan perencanaan detail gambar. Dari penelitian ini dibuat desain dekortikator dengan komponen rangka yang berfungsi sebagai pendukung utama komponen mesin, poros pemukul berfungsi untuk mengikis batang dengan bergerak cepat dan memecah lapisan luar batang sehingga serat dapat dipisahkan, silinder penggilas berfungsi menahan serat selama proses pemisahan serat dan batang, penutup mesin berfungsi untuk memberikan keamanan pada saat pengoperasian, motor bensin sebagai penggerak, dan sistem transmisi sabuk-puli. Mesin dekortikator selain dapat berfungsi untuk memisahkan serat dari bagian non-serat, juga dapat meningkatkan pemanfaatan serat alam yang ramah lingkungan sebagai material penyusun komposit dan mengurangi ketergantungan penggunaan material sintetis.

“…Composites are a type of material engineering that aims to obtain a new material. Composite comes from the word "to compose" which means to combine [3]. So a composite is a material in the manufacturing industry that consists of several mixtures or combinations of materials both micro and macro where the properties of the material are different in shape and chemical composition from the original substance [4].…”

A composite is a combination of 2 or more different materials. The composite joining process can use adhesives or mechanically by making holes. During the process of making holes in the composite, it can cause delamination in the composite. Delamination and layer thickness greatly influence the strength of hollow composite joints. This research aims to determine the effect of delamination factors and the number of layers on the tensile strength value of the composite. The materials used in this research are polyester resin and woven glass fiber. The method used is vacuum bagging with variations in the number of layers, namely 3 layers, 4 layers, 5 layers, and 6 layers. Tensile testing refers to ASTM D638 standards. Specimens that have been cut according to standards will then be perforated in the center with a hole diameter of 4 mm using a milling machine. The highest tensile strength value was obtained in the 6-layer variation of 237.448 MPa and the lowest value was obtained in the 3-layer variation of 186.221 MPa. The delamination value greatly influences the tensile strength of the composite, where the more layers, the delamination value will decrease and increase the tensile strength of the composite.

The plasterboard ceiling is one of the applications of fiber-based composite materials. Asbestos fibers, usually used to make plasterboard ceilings, are unfortunately harmful to humans. We propose using banana midrib fibers that are environment-friendly to replace asbestos fibers. This research investigates the influence of the percentage of banana midrib fibers on the fill weight, water absorption, and density of plasterboard ceilings. The fibers extracted from banana midrib were immersed in 40 mL of 1 M NaOH and then used to prepare plasterboard ceiling samples with different fiber percentages, namely 0.0%; 1.0%; 1.5%; 2% 2.5%. The fill weight, water absorption, and density of plasterboard samples were measured and then compared to Indonesian National Standard. The highest fill weight of 1.52 g/cm3 was obtained with a 1.0% percentage of banana midrib fibers for the plasterboard sample. In contrast, the highest water absorption of 11.84% was obtained at 2.5% banana midrib fibers. The more fibers added, the better the seepage of the plasterboard ceilings.Â
