Abstract
Pada tugas akhir ini, dilakukan percobaan untuk menilai karakteristik kekuatan dielektrik dari nanofluida yang dibuat dengan menggabungkan dua jenis minyak mineral yaitu minyak tua alami dan minyak tua yang dimanipulasi dengan dua nanopartikel hibrida yang berbeda: Fe3O4 dan TiO2. Stabilitas nanofluida ditentukan melalui uji PSA, uji tegangan tembus dilakukan di bawah tegangan AC dan data yang dihasilkan dianalisis menggunakan metode probabilitas Weibull, serta uji konduktivitas listrik dilakukan untuk menyelidiki dampak nanopartikel pada tingkat konduktivitas minyak mineral tua. Eksperimen dilakukan pada 1 hari dan 7 hari setelah pengendapan nanofluida. Nilai Z-Average nanofluida MO-NA dan MO-MA terbesar pada pengendapan 1 hari dan 7 hari adalah pada saat konsentrasi TiO2 tertinggi. Nanofluida MO-NA dengan nilai tegangan tembus terbesar pada tegangan AC adalah MO-NA/1 (kenaikan sebesar 97,05% pada 1 hari dan 80,17% pada 7 hari), dan kenaikan terkecil pada MO-NA/5 (kenaikan sebesar 3,37 % pada 1 hari dan 1,92% pada 7 hari). Sedangkan nanofluida MO-MA dengan nilai tegangan tembus terbesar pada tegangan AC adalah MO-MA/3 (kenaikan 98,30% pada 1 hari dan 98,02% pada 7 hari), dan kenaikan terkecil adalah MO-MA/1 (kenaikan sebesar 40,31% pada 1 hari dan 19,35% pada 7 hari). Hasil uji konduktivitas listrik menunjukkan bahwa nanofluida dengan konsentrasi TiO2 yang semakin besar memiliki nilai konduktivitas listrik yang semakin kecil.

In this final project, an experiment was conducted to assess the dielectric strength characteristics of a nanofluid created by combining two different types of mineral oil which is naturally aged oil and manipulated aged oil with two different hybrid nanoparticles: Fe3O4 and TiO2. The stability of the nanofluid was determined through a PSA test, the breakdown voltage test was performed under AC voltage and the resulting data was analyzed using the Weibull probability method, and electrical conductivity test was conducted to investigate the impact of nanoparticles on the conductivity level of aged mineral oil. The experiments were conducted at 1 day and 7 days after the nanofluid deposition. The greatest Z-Average value of MO-NA and MO-MA nanofluids at 1 day and 7 days deposition when the TiO2 dose is highest. The MO-NA nanofluids with the greatest breakdown voltage value at AC voltage were MO-NA/1 (increase of 97.05% on 1 day and 80.17% on 7 days), and the smallest increase was MO-NA/5 (increase of 3.37% on 1 day and 1.92% on 7 days). Meanwhile, the MO-MA nanofluids with the greatest breakdown voltage value at AC voltage were MO-MA/3 (an increase of 98.30% on 1 day and 98.02% on 7 days), and the smallest increase was MO-MA/1 (an increase of 40.31% on 1 day and 19.35% on 7 days). The results of the electrical conductivity test show that nanofluids with more TiO2 doses have smaller electrical conductivity values.
