Abstract

Durian rind fiber composite as a reinforcement is one of the interesting research areas. Some of the advantages associated with using natural fibers due to reinforcement in polymers are their non-abrasive properties and low-cost consumption. Durian rind when processed further can be made into cellulose fiber which can be used as a natural filler in unsaturated polyester composites. Among various types of natural fibers, durian skin fiber is an alternative polymer composite filler. Durian skin can be obtained easily because it is a family waste that has not been used. To get a new composite material made from durian skin waste, and to help the community and government in handling durian skin waste. The purpose of this study was to determine the maximum value of the variation of the volume fraction of durian skin fiber on the impact strength and hardness strength according to the desired application. This study uses the Hand Lay Up method, in the manufacture of single fiber composites with variations in volume fraction of durian skin fiber: polyester matrix, namely, 10%: 90%, 20%: 80%, 30%: 70%, 40%: 60% and 50 %:50%. The results showed that there was an increase in the impact strength and hardness strength with the addition of the volume fraction, where the highest impact energy for the volume fraction of durian skin fiber was 50%: 50%, 0.7738 J, and the highest impact value was 0.0096725 J/mm² and energy the lowest impact is 10%: 90%, 0.461 J. and the lowest impact price is 0.0057685 J/mm². So it can be concluded that the impact strength and hardness of the durian skin fiber composite increased with the increase in the volume fraction of the fiber.

Abstract

Tanah liat adalah bahan dasar membuat bata merah yang sumber daya alamnya melimpah di maluku, sedangkan serat sabut kelapa adalah merupakan potensi limbah alam yang sampai sekarang belum dikaji secara ilmiah dan dimanfaatkan untuk suatu tipe material. Sedangkan pati sagu dalam penelitian ini digunakan sebagai perekat yang nantinya dipakai pada saat pembuatan bata merah. Penelitian ini menggunakan metode Hand Lay Up, dalam pembuatan komposit serat tunggal dengan variasi fraksi volume tanah liat : serat sabut kelapa : matrik pati sagu yaitu, 50%:10%:40%, 50%:20%:30%, 50%:30%:20%, dan 50%:40%:10%. Komposisi komposit dibuat sesuai variasi fraksi volume yang sudah ditentukan, dan dicetakan dengan cara manual. Setelah itu specimen di keringkan pada suhu 130⁰C, selama 1 jam, kemudian dilakukan uji impak. Hasil penelitian adalah terjadi kenaikan kekuatan impak seiring penambahan fraksi volume, dimana energi impak tertinggi untuk fraksi volume 50% : 40%:10%, sebesar 2.38 J, dan energi impak terendah pada fraksi volume 50% : 10%:40%, sebesar 1.67 J. dan harga impak tertinggi untuk fraksi volume 50% : 40%:10%, sebesar 0.030 J/mm2, dan energi impak terendah pada fraksi volume 50% :10%:40%, sebesar 0.021 J/mm2. Sehingga dapat disimpulkan bahwa kekuatan impak komposit serat sabut kelapa dan tanah liat yang diperkuat pati sagu mengalami peningkatan seiring dengan bertambahnya fraksi volume serat.
