Abstract

ABSTRACTMaterial physics is an important branch of science that studies the properties and applications of various materials from atomic level as the foundation for modern technological development. The importance of this field encouraged the implementation of a socialization activity aimed at improving students’ understanding of the basic concepts and applications of material physics. The activity was attended by 22 participants and consisted of three stages: an initial survey, socialization using the one group pretest–posttest design through interactive and contextual methods, and data evaluation. The average pretest score of 2.22 increased to 3.45 in the posttest, indicating an improvement based on the Likert scale. These results show that the socialization activity contributed positively to enhancing participants’ understanding and interest in the concepts and applications of material physics. The interactive approach used in the socialization proved effective in strengthening participants’ motivation and insight into this field.Keywords: Physics, material, educationABSTRAKFisika material merupakan cabang ilmu penting yang mempelajari sifat dan aplikasi berbagai material dari tingkat atomik sebagai dasar pengembangan teknologi modern. Pentingnya bidang ini mendorong dilaksanakannya kegiatan sosialisasi yang bertujuan meningkatkan pemahaman siswa terhadap konsep dasar dan penerapan fisika material. Kegiatan diikuti oleh 22 peserta dengan tiga tahap: survei awal, sosialisasi menggunakan metode one group pretest–posttest design secara interaktif dan kontekstual, serta evaluasi hasil. Nilai rata-rata pretest 2,22 meningkat menjadi 3,45 pada posttest, menunjukkan peningkatan poin berdasarkan skala Likert. Hasil ini menunjukkan bahwa kegiatan sosialisasi berkontribusi positif dalam meningkatkan pemahaman dan ketertarikan peserta terhadap konsep serta aplikasi fisika material. Pendekatan sosialisasi yang interaktif terbukti efektif untuk memperkuat minat dan wawasan peserta terhadap bidang ini.Kata Kunci: Fisika, Material, Edukasi

Abstract

Telah berhasil dibuat membrane separator yang berpotensi diaplikasikan untuk baterai lihitum-ion, membrane separator digunakan untuk proses transfer ion dan mencegah terjadinya arus pendek. Dalam penelitian ini membrane separator PVA/SiO2 disintesis memggunakan metode electrospinning dengan variasi berat SiO2 (0, 0.6, 1.2, 2) wt%. SiO2 yang digunakan adalah hasil ekstraksi silika sekam padi. Pengaruh penambahan SiO2 pada PVA untuk meningkatkan karakteristik membrane diantaranya porositas, dan stabilitas pada suhu tinggi. Hasil membrane yang berhasil dibuat PVA, dan PVA/SiO2 membentuk serat nano dengan ukuran diameter serat semakin kecil ketika ditambahkan  SiO2 yaitu ~ 220 nm, ukuran diameter semakin kecil  meningkatkan porositas membrane dan meningkatkan kinerja membrane dengan stabilitas suhu 165 oC

Abstract

In order to coat the layer of the Cu for an anode-free lithium battery (AFLB) and examine AFLB performance, PVDF nanofiber with electrospinning is used. The fabrication time and molecular weight of the nanofiber can be modified. In comparison to conventional models, the AFLB is one of the new model options that provides great energy density at the same battery size. The disadvantages of this new model battery include its limited electrochemical performance and the fact that it is still in its initial stages of manufacturing. Low Coulombic efficiency and uncontrolled dendritic growth are challenges in the growth of AFLB. For the fabrication of nanofiber membranes were synthesized with different types of PVDF Mw 1.300.000 and 534.000, PVDF Nanofibers were made using electrospinning with time variations of 5 hours, 7 hours, and 9 hours, and their thermal, mechanical, and porosity properties were examined. The PVDF Mw 1.300.000 sample had the greatest porosity percentage value which is 47.031% during a 9-hour time. The PVDF Mw 534.000 sample had the highest tensile strength results, with a variation of 2.33 MPa during a 9-hour time. The PVDF Mw 1.300.000 sample had the highest percentage elongation results, 39.7%. The average nanofiber size varies with processing time, with the PVDF Mw 1.300.000 sample having the smallest size at 167.9 nm.
