Abstract

Sintesis nanopartikel tembaga (CuNPs) telah berhasil dilakukan pada penelitian ini. CuNPs mudah mengalami oksidasi apabila terjadi kontak dengan udara. Oleh karena itu diperlukan adanya agen penstabil dalam sintesis CuNPs. Agen penstabil yang dipelajari pada penelitian ini adalah ekstrak daun ruku-ruku (Ocimum tenuiflorum) dari Kabupaten Sumbawa, NTB. Tujuan dari penelitian ini adalah menghasilkan CuNPs menggunakan agen penstabil yang ramah lingkungan dan mengetahui hasil Response Surface Methodology (RSM) Desain Box-Behnken dengan variasi konsentrasi CuSO4, waktu sonikasi serta temperatur yang digunakan selama proses sintesis. Hasil sintesis CuNPs kemudian diuji menggunakan spektrofotometer UV-Vis, FTIR, XRD, PSA dan TEM. CuNPs hasil sintesis memiliki bentuk yang bulat (sperichal) dan berukuran rata-rata 23,91 nm. Optimasi menggunakan RSM dengan desain Box-Behnken menghasilkan pengolahan yang optimal pada 300 nm dengan konsentrasi CuSO4, temperatur, dan waktu sonikasi masing-masing 0,1–0,2 M, 67,5–70ºC, dan 5–6,5 jam. Pada 800 nm menunjukkan kondisi yang optimal dengan konsentrasi CuSO4, temperatur dan waktu sonikasi masing-masing 0,1–0,15 M, 50–52,5ºC dan 4–5,5 jam.

The synthesis of copper nanoparticles (CuNPs) has been successfully carried out in this study. CuNPs were easily oxidize when they come in contact with air. Therefore a capping agent was needed in the synthesis of CuNPs. The stabilizing agent that studied in this research was the extract of ruku-ruku leaves (Ocimum tenuiflorum) from Sumbawa, West Nusa Tenggara. Indonesia. The aims of this study were to synthesize CuNPs using environmentally friendly stabilizing agents and find out the results of the Response Surface Methodology (RSM) Box-Behnken Design with variations in CuSO4 concentration, sonication time and temperatures that used during the synthesis process. The CuNPs that synthesiez were analyzed using UV-Vis, FTIR, XRD, PSA and TEM spectrophotometers. CuNPs have a sperichal shape with average size of 23.91 nm. Optimization result using Response Surface Methodology Box-Behnken Design obtain that the optimum at a peak of 300 nm for concentration of CuSO4, temperature, and sonication time were 0.1–0.2 M, 67.5–70ºC and 5–6.5 hours, respectively. At a peak of 800 nm obtain that the optimum for concentration of CuSO4, temperature, and sonication time are 0.1–0.15 M, 50–52.5ºC and 4–5.5 hours, respectively.
