Abstract

Dalam penelitian ini dilakukan pembuatan material nano komopsit hasil pencampuran 50 wt % material BSHF dan 50 wt %  material BST dengan menggunakan metoda mekanikal alloying dan sonikasi. Material di milling selama 80 jam, dilanjutkan  dengan pemanasan sampai 1100 oC selama 4 jam. Material yang sudah dalam bentuk Kristal di milling lagi selama 20 jam dan dilanjutkan dengan proses sonikasi selama 6 jam untuk mendapatkan material nano komposit.setelah pengeringan, dilakukan  pembuatan bulk dan dilanjutkan dengan karakterisasi XRD dan Fermagraph.. Material kedua dilakukan proses pembuatan  bulk sambil diinduksi magnet dari luar sebesar 5 mT. dan dilanjutkan dengan Fermagraph. Hasilnya memperlihatkan terjadi  perubahan sifat magnet dari material nano komposit. di indikasikan dengan perubahan nilai remanen dan nilai koersivitas  dari material.. Pengaruh induksi magnet pada material nano komposit BSHF / BST mengakibatkan perubahan nilai remanen sebesar 15 % dan nilai koersivitas 30 %. Kata kunci :, Mechanical Alloying , sonikasi induksi magnet remanen, dan koersivitas

Abstract

In order to meet the needs and desires of human life, science and technology have experienced rapid progress. Science and technology have developed in various aspects of life. Technological progress has also occurred in composite materials which are still being researched. Particle board is an artificial board made by pressing industrial waste from plantations, forestry, and agriculture together with organic adhesives. Low-quality wood waste products that may contain cellulose and lignin, such as sawdust, twigs, turning residues, and others, can be utilized. In this study, which was carried out using the direct experimental method. The parameters used were mesh 10, 20, and 30 with volume fractions of 60%: 40%, 70%: 30%, and 80%: 20%. In this study, the results of the largest impact strength were found in the volume fraction of 60%:40% on mesh 30 with a result of 16.34 J/m2 and the smallest impact value was found in the volume fraction of 70%:30% on mesh 10 of 9.28 J/m2 where this value does not meet the SNI-03-2105-2006 standard for making particle boards.

Abstract

In order to satisfy the wants and desires of human life, science and technology have advanced quickly. Science and technology are developing in many facets of life. Technological advancements also happen in composite materials, which are still being studied today. Particleboard is a manufactured board created by pressing industrial waste from plantations, forestry, and agriculture together with organic adhesives. Low-quality wood waste products that may contain cellulose and lignin, such as sawdust, twigs, lathing residue, and others, can be used. The PVAc polymer was subjected to temperatures of 90°C, 100°C, and 110°C in this work, which employed a direct experimental method. The parameters used were mesh 10, 20, and 30 with a volume fraction of 60%: 40%, 70%: 30%, and 80%: 20%. In this study, the results of the largest impact strength were found in the volume fraction of 60%:40% on mesh 30 with heating at 90°C for 15 minutes amounting to 16.34 J/m2, and the smallest impact value was found in the volume fraction of 70%:30% on mesh 10 with heating at 100°C amounting to 9.28 J/m2, where these values do not meet the SNI-03-2105-2006 standard for making particle boards.
