Abstract

Fly ash is a solid waste product resulting from the combustion of coal or biomass that contains various valuable metals such as Si, Al, Fe, Ca, and Mg. The utilization of fly ash as a source of secondary metals is considered important from both economic and environmental perspectives. Various extraction methods have been applied, including conventional acid leaching, biogenic leaching, alkali leaching, and hydrometallurgy; however, each has limitations regarding efficiency and environmental impact. This study examines the application of a microwave-assisted extraction method that utilizes rapid and uniform heating to enhance the metal dissolution process. Comparative results from various sources indicate that extraction via the microwave method yields higher metal recovery than other methods, such as conventional hydrometallurgical, biogenic, and pyrometallurgical approaches, particularly for aluminium compounds, with recoveries of around 95-96%. The advantages of this method are associated with lower solvent consumption, shorter processing times, higher energy efficiency, and greater environmental friendliness. Thus, the microwave-assisted method is the most effective and efficient technique for metal extraction from fly ash, regardless of the need for further research on industrial-scale applications.

Abstract

Daun sirsak (Annona muricata L.) diketahui mengandung senyawa fitokimia, terutama flavonoid, yang berpotensi sebagai antioksidan dan anti kanker. Senyawa flavonoid dapat diperoleh melalui proses pemisahan seperti ekstraksi dengan memanfaatkan gelombang mikro yang mampu mempercepat proses ekstraksi. Penelitian ini bertujuan menentukan kondisi optimum ekstraksi flavonoid dari daun sirsak menggunakan metode microwave-assisted extraction (MAE). Proses ekstraksi dilakukan pada daya 264 W dan 440 W dengan variasi waktu 30, 45, 60, 75, dan 90 menit. Hasil ekstraksi dianalisis berdasarkan rendemen, kadar flavonoid total, dan identifikasi gugus fungsi melalui FTIR. Kondisi optimum nilai rendemen diperoleh pada daya 440 W selama 30 menit dengan rendemen 20,35 %, sedangkan kadar flavonoid tertinggi mencapai 303,642 ppm pada daya 440 W selama 90 menit. Analisis FTIR menunjukkan adanya pita serapan pada 300–3200 cm⁻¹ yang mengindikasikan gugus hidroksil (–OH) khas senyawa flavonoid.

Abstract

Optimization of anthocyanin pigment extraction from butterfly pea flowers (Clitoria ternatea L.) is an important focus to increase the efficiency of obtaining valuable active compounds. This study marks an initial approach in the application of Microwave-Assisted Extraction (MAE) using 0.75% aquadest-tartaric acid solvent, with the hope of producing more stable anthocyanins. The main objectives of this study were to identify the effect of the solvent-material ratio, extraction duration, and MAE power level on anthocyanin levels (mg/L) through the One-Factor-At-a-Time (OFAT) method. The results showed that the optimal treatment was obtained at condition P17, with a solvent-material ratio of 1:15, an extraction time of 15 minutes, and an MAE power of 450 watts, which produced an anthocyanin level of 33.89 ± 0.47 mg/L. These findings confirm that increasing the solvent-material ratio to the optimal point contributes to increasing anthocyanin recovery. However, excessive MAE time and power can cause pigment degradation. The optimal ratio variables were found to be in the range of 1:15 to 1:25, extraction time 9–15 minutes, and MAE power 270–450 watts. This study is expected to be the basis for further optimization using the Response Surface Methodology (RSM) method which allows for deeper analysis of the interactions between variables.
