Abstract


Makalah ini bertujuan mengkaji kelayakan ekonomi produksi nanopartikel Fe3O4 dari skala laboratorium menjadi skala industri. Evaluasi dilakukan menggunakan 2 model studi kelayakan, yaitu: analisis teknik dan evaluasi ekonomi. Analisis teknik memberikan informasi potensi produksi berskala besar dan hasil proses ini dapat diterapkan menggunakan peralatan yang tersedia secara komersial dan murah. Evaluasi ekonomi dilakukan berdasar perbandingan grafik Cumulative Net Present Value pada keadaan ideal dan grafik pada saat dilakukan perubahan parameter (seperti perubahan nilai kurs dollar, kuantitas produk penjualan, dan besar nilai gaji karyawan). Dari hasil evaluasi, semua perubahan parameter memberikan nilai positif yang menunjukkan bahwa proyek ini layak dijalankan secara komersial dan dalam skala besar. Hal ini karena hasil evaluasi memberikan kestabilan indeks keuntungan pada beberapa perubahan nilai parameter. Studi ini menunjukkan bahwa fabrikasi Fe3O4 dapat memberikan laba yang menjanjikan di negara berkembang dan dapat menarik investor asing untuk bekerja sama dalam fabrikasi Fe3O4.

This paper aims to evaluate the economic feasibility of Fe3O4 nanoparticle production from a laboratory scale to an industrial scale feasibility. The evaluation was conducted using 2 models of feasibility studies, namely: technical analysis and economic evaluation. Technical analysis provides information on the potential for large-scale production and the results of this process can be applied using commercially available and inexpensive equipment. Economic evaluation is based on a comparison of the Cumulative Net Present Value graph in an ideal condition and the graph when parameters changing are made (such as changes in the dollar exchange rate, the quantity of sales products, and the value of employee salaries). From the evaluation results, all parameter changes give a positive value indicating that the project is feasible to run commercially and on a large scale. This is because the evaluation results provide a stable index of profit for some changes in parameter values. This study shows that Fe3O4 fabrication can provide promising profits in developing countries and can attract foreign investors to work together on Fe3O4 fabrication.
