Abstract

Paper ini membahas masalah kenerja material bio-composite untuk dapat ditingkatkan menjadi material struktural. Untuk hal tersebebut maka paper ini di beri judul “Justifikasi Karakteristik Mekanik Material Bio-Composite Serat Rami Epoxy dan Deteksi Kerusakannya”. Material biocomposite merupakan material yang memanfaatkan kondisi alam ataupun partikel alam yang bahkan telah menjadi sampah. Dengan demikian perkembangannya akan mendongkrak masyarakat untuk lebih berinovasi. Dari penelitian ini diketahui bahwa kekuatan tarik serat ramin mencapai lebih dari 120 MPa, sehingga cukup baik untuk dijadikan bahan kajian pada struktural. Hasil penelitian menunjukkan bahwa serat ramin dan resin epoxy memiliki sifat yang lebih baik dalam uji tarik dibandingkan dengan bio-composite lainnya. Ada pengurangan kekuatan yang signifikan ketika serat hibrida menggatikan fiber karbon dan fiber glass atau yang lainnya. Oleh karena itu sifat tarik komposit hibrida telah diselidiki ini masih menuntut riset lebih lanjut dengan peralatan yang lebih maju.

Abstract

Tapak Siring Village, Sukau District, West Lampung Regency, where most of the people work as farmers and one of their agricultural commodities is chayote. The problem faced by this community is limited knowledge in innovating food products to increase sales value, so that chayote is only processed into daily food ingredients, and also used as animal feed. Based on this problem, an activity will be carried out in the form of training on processing chayote-based ingredients into creative and innovative food products, namely making chayote jam. This activity aims to help the community, especially mothers in fostering family welfare in increasing their knowledge and skills in diversifying food products. It was carried out on January 26 and at the TAPAK SIRING 2 KKN residence post. The method used was through the implementation of activities in the form of product manufacturing training. The result of this activity is that the community is able to increase their knowledge and develop their creativity in processing chayote into innovative food products, namely jam.

Abstract

Gasoline engine vehicles are vehicles that use 2 fuels, namely air and gasoline. In this test, it was observed that the fuel pump fastening bolt was damaged. This damage needs to be analyzed and examined to determine the cause of the damage to the fastening bolt component. The methods used to research bolt components include visual inspection, fractography, hardness testing, and Finite element method analysis using Solidworks software. From the results of the fractography test, it was determined that the damage to the bolt was caused by a torsional moment, leading to a fatigue fracture. The material used in the bolt component is ASTM A36. To validate the bolt material and determine the hardness value of the ASTM A36 material, a hardness test using the Vickers method was required, and the hardness results obtained for the ASTM A36 material were around 259.6 HV. The next test was to analyze the bolt to determine the torsional moment that occurred using the FEM method from the SolidWorks software. After the FEM test was carried out by providing a torque of 20 kgf on the bolt component, the bolt component broke due to holding an excessive load. Thus, the cause of damage to bolt components is due to excessive moment loads and material quality degradation.
