Studi Eksperimen Kekerasan Material Kampas Rem Sepeda Motor Berbahan Biomaterial Arang Kulit Pisang
No full textThis research aims to develop environmentally friendly brake camoas by utilising banana peel charcoal as filler material, replacing asbestos which is a health risk. Banana peel charcoal was mixed with polyester resin as the matrix, with variations in composition (35% and 45%) and particle size (100 mesh and 200 mesh). The mixing process was carried out carefully to produce a homogeneous and air bubble-free material. Hardness testing was conducted using a Shore D type durometer with five test points on each specimen. The test results showed that the specimen with 35% charcoal content and 200 mesh particle size produced the highest hardness value, 81.2 HD. This indicates that the finer the particle size and the higher the resin content, the denser and harder the material structure. The combination provides optimal mechanical performance, making banana peel charcoal a potential, low-cost, and environmentally friendly alternative brake lining material. Further research is recommended to evaluate the wear properties and thermal resistance for wide application in the automotive industry.Penelitian ini bertujuan untuk mengembangkan kampas rem yang ramah lingkungan dengan memanfaatkan arang kulit pisang sebagai bahan pengisi, menggantikan asbes yang memiliki risiko kesehatan. Arang kulit pisang dicampur dengan resin polyester sebagai matriks, dengan variasi komposisi (35% dan 45%) dan ukuran partikel (100 mesh dan 200 mesh). Proses pencampuran dilakukan dengan hati-hati untuk menghasilkan material yang homogen dan bebas gelembung udara. Pengujian kekerasan dilakukan dengan menggunakan durometer tipe Shore D dengan lima titik uji pada setiap spesimen. Hasil pengujian menunjukkan bahwa spesimen dengan kadar arang 35% dan ukuran partikel 200 mesh menghasilkan nilai kekerasan tertinggi, yaitu 81,2 HD.

PENGARUH SUSUNAN PADA KOMPOSIT LAMINAT SERAT SABUT KELAPA TERHADAP KEKUATAN BENDING DAN KETANGGUHAN IMPAK
Full text linkNatural fibers have emerged as promising reinforcement materials in composite applications due to their abundance, low density, and favorable specific strength. Composites reinforced with natural fibers are not only environmentally friendly but also demonstrate improved mechanical properties and energy absorption capabilities, making them suitable as alternative structural materials. The stacking sequence and fiber orientation have been shown to significantly affect the flexural and impact performance of laminated composites. This study aims to investigate the effect of different stacking sequences on the flexural and impact properties of laminated composites reinforced with coconut coir fibers. The composites were fabricated using woven and randomly oriented coconut fibers that were alkali-treated with 5% NaOH for 2 hours and dried at 80°C for 3 hours. Unsaturated polyester resin with MEPOXE catalyst served as the matrix, and the hand lay-up method was used for fabrication. Three stacking variations were examined: woven–woven–woven, woven–random–woven, and random–woven–random. Flexural testing was conducted according to ASTM D790, while impact testing followed the Charpy method based on ASTM D6110. The results showed that the woven–woven–woven configuration produced the highest flexural strength of 41.23 MPa. Meanwhile, the random–woven–random configuration exhibited the highest energy absorption and impact toughness, reaching 2.84 J and 0.0295 J/mm², respectively. These findings confirm that woven layers contribute to superior flexural strength, while random fiber arrangements on the outer surfaces enhance energy absorption. Therefore, the stacking sequence plays a crucial role in determining the mechanical performance of coconut coir fiber-reinforced laminated composites
