Abstract

A composite is a material structure formed from a combination of two or more materials, processed on a macroscopic scale and physically fused. To improve the characteristics of natural fibers in composites, a NaOH alkalization process is carried out which influences the fiber composites. Real experimental strength of the composite. The results showed that Alkalization of NaOH in water hyacinth fiber with variations in resin and fiber fractions (40%, 50%, 60%) and concentration (5% and 10%) affected the impact value. Specimens with a 60% resin and fiber fraction that experienced 5% alkalization showed the lowest impact, while a 40% resin and fiber fraction that experienced 10% alkalization had the highest impact. These findings indicate that NaOH alkalization significantly affects water hyacinth fibers, potentially increasing strength due to the removal of lignin, hemicellulose, and pectin. Loss of these components can make the fiber more brittle and susceptible to damage. In testing the resin and fiber fractions (40%, 50%, 60%) with varying concentrations (5% and 10%) when mixing fiber with matrix, it was found that the 60% resin and fiber fraction with a concentration of 5% had the lowest impact strength of 61 J/mm2, while the resin and fiber fraction of 40% with a concentration of 10% has the highest strength of 82 J/mm2. The results of this research highlight the importance of optimizing the volume fraction of fiber and epoxy matrix to improve the impact characteristics of water hyacinth fiber composites.Keywords: composite, alkalization, volume fraction, fiber, water hyacinth

Abstract

The automotive industry is one of the industries that is currently developing in Indonesia. Research has been carried out on materials used in the automotive industry, one of which is improving the mechanical properties of low carbon steel which is widely used as sprocket material. Sprockets are parts of a motorbike that require surface hardness and ductility at the core. So carburizing treatment is the right treatment to increase the wear resistance of low carbon steel. The material used in this research is ST 37. This research aims to increase the surface hardness of ST 37 by varying the carburizing temperature, where the temperatures used are 850℃ and 900℃ with a holding time of 3 hours. Wear resistance testing uses the weight loss method by comparing the ST 37 sprocket with sprockets sold on the market. The highest wear resistance was obtained on sprockets with carburizing treatment at a temperature of 900℃ with test results of 1.65 x 10-2 mm3/hour.

Abstract

Penelitian ini bertujuan untuk menganalisis perbandingan makrostruktur hasil cor dengan variasi komposisi pasir cetak. Pasir cetak memegang peran penting dalam proses pengecoran logam, karena sifatnya memengaruhi kualitas produk cor yang dihasilkan. Variasi komposisi pasir cetak, seperti persentase pasir silika, binder, dan air, diuji untuk mengamati pengaruhnya terhadap struktur makro hasil cor, termasuk cacat permukaan, kekerasan, dan homogenitas. Proses pengecoran dilakukan menggunakan metode sand casting dengan bahan logam tertentu, serta parameter proses yang terstandarisasi. Hasil pengamatan menunjukkan bahwa variasi komposisi pasir cetak memberikan dampak signifikan terhadap kualitas permukaan dan struktur internal hasil cor. Komposisi pasir cetak yang optimal mampu menghasilkan struktur makro yang lebih seragam, minim cacat, dan sesuai dengan standar kualitas industri. Penelitian ini diharapkan dapat memberikan kontribusi dalam meningkatkan efisiensi dan kualitas proses pengecoran di industri manufaktur.

Abstract

Sektor pertanian di Indonesia, khususnya subsektor pasca-panen, memegang peran penting dalam menjamin ketersediaan pangan nasional. Salah satu alat yang krusial dalam proses ini adalah mesin penggiling padi, yang berfungsi untuk mengubah gabah menjadi beras siap konsumsi. Kinerja mesin ini sangat dipengaruhi oleh kekuatan dan kestabilan rangka sebagai struktur penyangga utama seluruh komponen mekanis. Penelitian ini bertujuan untuk mengevaluasi performa rangka mesin penggiling padi menggunakan material ASTM A500 Grade B melalui pendekatan simulasi berbasis analisis elemen hingga (Finite Element Analysis - FEA). Metode penelitian mencakup tahapan pengumpulan data teknis, pemodelan geometri menggunakan perangkat lunak CAD, pembebanan berdasarkan data beban statis sebesar 50.825 N dan beban dinamis sebesar 442 N, serta simulasi elemen hingga menggunakan perangkat lunak FEA. Material ASTM A500 Grade B digunakan dengan sifat mekanis meliputi modulus elastisitas sebesar 200 GPa, kekuatan tarik leleh 345 MPa, dan densitas 7,85 g/cm³. Analisis melibatkan deformasi total, tegangan geser, tegangan normal, serta evaluasi faktor keamanan dengan menetapkan kondisi tumpuan tetap (fixed support) pada titik penopang rangka. Hasil simulasi menunjukkan deformasi maksimum pada rangka adalah 4.3967 × 10⁻⁷ m, tegangan geser maksimum 15.436 kPa, tegangan normal maksimum 15.550 kPa, dan faktor keamanan minimum mencapai 15, yang jauh di atas nilai minimum yang disyaratkan. Studi ini mengindikasikan bahwa rangka memiliki kekakuan dan ketahanan struktural yang memadai untuk menahan beban operasi. Simulasi ini memberikan wawasan desain yang aman dan efisien untuk aplikasi mesin penggiling padi di sektor pertanian, sekaligus menjadi referensi dalam meningkatkan keandalan struktur rangka pada mesin industri lainnya.
