Abstract

Palm Oil Industries, not only provide so many benefits, but also has a negative impact in the form of organic waste as by products of palm oil industries. Therefore, the utilization of oil palm fiber waste needs to be developed, including for structural components that retain load, through various studies in order to reduce the volume of waste caused by oil palm. One of the simplest types of load is axial load. The purpose of this study is to make polymer matrix composite materials reinforced with oil palm  fiber, and then test the life cycle of fatigue failure axial load, of polymer matrix composite materials with several different percentages of fiber content. The material used as a matrix is Yukalac® 157 BTQN-EX unsaturated polyester resin (UPRs), and the catalyst uses methyl ethyl ketone peroxide (MEKPO) and Oil palm fibers as reinforcement. The content of palm oil fiber is divided into three level i.e: 3%, 5%, and 7%. The effect of the percentage content of the volume of palm oil fiber on the cycle of fatigue failure of the polymer matrix composite material were analyzed. So that later this palm matrix resin fiber composite material can really be utilized for structural components that retain load. By utilizing palm oil fiber in the production of composite materials, it is hoped that this will reduce the volume of organic waste from palm oil processing. Fatigue testing results on the percentage of palm oil fiber content of 3% obtained the shortest failure cycle life is 7.67 cycles. As for the percentage of palm oil content of 7%, the longest failure cycle was obtained to 18.33 cycles.

Abstract

Rangka merupakan bagian terpenting dari kendaraan yang berperan sebagai struktur yang memegang komponen-komponen penting lainnya. Pada penelitian ini, rangka struktur yang digunakan pada kendaraan AMMDes (Alat Mekanis Pedesaan) dianalisis secara numerik menggunakan perangkat lunak Solidworks. Salah satu faktor yang penting untuk diketahui apakah struktur rangka ini mempunyai kemampuan sesuai dengan kapasitas daya angkut yang ditentukan. Oleh karena itu, rangka struktur AMMDes dianalisis secara numerik untuk mengetahui berapa besar tegangan kritis dan perubahan bentuk yang terjadi pada saat beban diaplikasikan. Hasil dari simulasi numerik menunjukkan adanya tegangan yang terakumulasi pada titik tertentu. Dengan adanya konsentrasi tegangan ini, maka dapat memicu kemungkinan terjadinya kegagalan atau perubahan bentuk yang sangat signifikan pada area tersebut. Untuk itu, pelat penyambung diaplikasikan pada struktur rangka AMMDes untuk mendistribusikan tegangan ke struktur secara lebih merata dan struktur dianalisis kembali untuk mengetahui pengaruh yang ditimbulkan dari perubahan ini. Penambahan pelat penyambung atau connection plate pada area yang dimaksud di atas, terbukti dapat meningkatkan kekakuan dari struktur dan mengurangi tegangan yang muncul.
