Abstract

Sugar cane fiber is an organic waste mostly produced by sugar factories in Indonesia such as in Gorontalo Province. If it is properly processed, it will have high economic value and will help the community’s economy during Covid 19 pandemic. This fiber, however, is easy to find, and it is not dangerous for human health. The important thing is that this fiber can be degraded naturally. Hence it can be used as composite reinforcing fiber which can help overcome environment problems. This study aimed at investigating the physical characteristics of natural fiber composite-based new material with characteristics and structures which can be used for automotive industry. The method applied in this study was by doing physical test such as density, water content, water absorption level, and thickness development with random-pattern treatments consisting of fraction variations of sugar cane fiber volumes of 10%, 30%, and 50% and fraction variations of resin volumes of 90%, 80%, and 70%. Each treatment consisted of 3 specimens with determined size, and they were tested in laboratory in order to find out the physical. Findings revealed that the highest density was in specimen 3 with fiber volume of 50% and resin volume of 70%, and the average value was 1.162 g/cm3. Meanwhile, the highest water content was specimen 1 with fiber volume of 10% and resin volume of 90% obtaining value of 0.51%. The water absorption level during 24 hours that obtained maximal result and value of 6.89% was specimen 2 with fiber volume of 30% and resin volume of 80%. The result for thickness development during 24 hours that obtained value of 10% was specimen 1 with fiber volume of 10% and resin volume of 90%. If it is validated with Indonesian National Standard, some of physical test results should be further formulated to get result based on Indonesian National Standard. Regarding the explanation, the fiber volume and resin volume fractions highly influenced the natural fiber (sugar cane fiber) composite-based new material making and it can be used for automotive industry.

Abstract

3D printing menggunakan material carbon fiber menjadi semakin populer dalam industri manufaktur karena karakteristiknya yang ringan dan memiliki kekuatan mekanik tinggi. Namun, kekasaran permukaan yang optimal tetap menjadi tantangan dalam proses 3D printing menggunakan material ini. Penelitian ini bertujuan untuk mengoptimalkan kekasaran permukaan pada proses manufaktur 3D Printing menggunakan metode Taguchi pada material carbon fiber. Parameter 3D printing yang dioptimasi diantaranya yaitu nozzle temperature, infill density, printing speed, layer thickness, infill patern dan orientasi. Proses 3D printing dilakukan dengan menggunakan mesin FlashForge Guider II. Adapun pengukuran kekasaran permukaan menggunakan alat Handysurf.  Hasil penelitian menunjukkan bahwa parameter yang optimal untuk mencapai kekasaran permukaan yang minimal adalah nozzle temperature 240°C, orientasi 0°, printing speed 60 mm/s, layer thickness 0.1 mm, infill pattern line, dan infill density 40%. Hasil ini telah diverifikasi dengan eksperimen konfirmasi dan menunjukkan bahwa kombinasi parameter optimal tersebut menghasilkan kekasaran permukaan yang minimal. Parameter-parameter optimal yang diidentifikasi melalui pendekatan ini dapat digunakan untuk meningkatkan kualitas produk akhir, serta membuka peluang penggunaan lebih luas dari material carbon fiber dalam berbagai aplikasi industri.
