Abstract
Penelitian ini bertujuan untuk mengoptimalkan metode leaching Fe dari batuan laterit menggunakan desain eksperimen Central Composite Design (CCD) dalam Response Surface Methodology (RSM). Batu laterit yang digunakan dalam penelitian ini berasal dari Kendari, Kolaka, Sulawesi Tenggara. Proses pemisahan besi dari batu laterit dilakukan dengan metode leaching. Metode leaching dilakukan dengan variasi rasio padatan/cairan (S/L), waktu pelindian, dan Temperatur leaching. Hasil dari proses leaching di analisa menggunakan Atomic Absorbtion Spectroscopy (AAS) untuk mengetahui konsentrasi besi hasil leaching. Hasil penelitian menunjukkan bahwa rasio S/L, waktu pelindian, dan Temperatur leaching berpengaruh signifikan terhadap konsentrasi Fe yang terekstraksi. Optimasi kondisi proses menggunakan CCD-RSM menghasilkan kondisi optimal pada rasio S/L sebesar 1:1, waktu leaching selama 90 menit, dan temperatur 80°C dengan konsentrasi Fe yang terekstraksi sebesar 19,2%. Hasil ini menunjukkan bahwa metode CCD-RSM efektif digunakan untuk mengoptimalkan proses leaching Fe dari batu laterit, yang dapat mengurangi potensi limbah berbahaya dan meningkatkan efisiensi ekstraksi Fe. Selain itu, penggunaan CCD-RSM dalam optimasi proses menunjukkan keakuratan dalam menentukan kondisi terbaik dengan jumlah percobaan yang lebih sedikit dibandingkan metode one factor at a time (OFAT). Dengan demikian, penelitian ini tidak hanya berkontribusi pada peningkatan efisiensi proses ekstraksi Fe, tetapi juga memberikan metode yang dapat diadaptasi untuk ekstraksi logam lainnya dari batu laterit atau material serupa.

This research aims to optimize the leaching method of Fe from laterite rocks using the Central Composite Design (CCD) experimental design in the Response Surface Methodology (RSM). The laterite rock used in this study was obtained from Kendari, Kolaka, Southeast Sulawesi. The separation of iron from laterite rock was carried out using the leaching method. The leaching method was conducted with variations in the solid/liquid (S/L) ratio, leaching time, and leaching temperature. The results of the leaching process were analyzed using Atomic Absorption Spectroscopy (AAS) to determine the concentration of the extracted iron. The results showed that the S/L ratio, leaching time, and leaching temperature had a significant effect on the concentration of extracted Fe. The optimization of the process conditions using CCD-RSM resulted in optimal conditions at an S/L ratio of 1:1, a leaching time of 90 minutes, and a temperature of 80°C with an extracted Fe concentration of 19.2%. These results indicate that the CCD-RSM method is effectively used to optimize the leaching process of Fe from laterite rocks, which can reduce the potential for hazardous waste and improve the efficiency of Fe extraction. Furthermore, the use of CCD-RSM in the optimization process demonstrates accuracy in determining the best conditions with fewer experiments compared to the one-factor-at-a-time (OFAT) method. Thus, this research not only contributes to improving the efficiency of the Fe extraction process but also provides a method that can be adapted for the extraction of other metals from laterite rocks or similar materials.
