Abstract

The leaves of Anredera cordifolia, or binahong, are one of the herbal plants with a high potential for antioxidants and have been reported to be rich in flavonoids. This study aimed to determine the best operating conditions in the ultrasonication extraction method from binahong leaves extract on the yield obtained. Experiments were conducted into how extraction conditions affected the ultrasonication extraction of binahong leaves. Different extraction parameters, such as ethanol concentration (20–100%), time (10–40 min), temperature (30–70 C), and yield impacts, were used to extract powdered dried binahong leaves. The results showed all extraction parameters to have significant effects on yield obtained. The maximum yield of extract from binahong leaves was obtained at 60 ml of ethanol concentration, 20 minutes of extraction time, and 50°C ultrasonication bath temperature. Thus, it can be concluded that the ultrasonication process is a good way to obtain a better yield of simplicia of binahong leaves extract as a therapeutic herbal in the future.

Abstract

Proses produksi amonia memerlukan tahapan penghilangan karbon dioksida (CO₂) agar gas sintesis terbebas dari senyawa pengganggu yang dapat merusak katalis. Salah satu unit penting dalam proses ini adalah kolom stripper yang berfungsi untuk melepaskan CO₂ dari larutan semi-lean agar dapat digunakan kembali dalam siklus penyerapan. Penelitian ini bertujuan untuk mengevaluasi kinerja stripper berdasarkan perbandingan data desain dan data aktual yang diperoleh dari Distributed Control System (DCS) dan analisis laboratorium selama lima bulan. Evaluasi mencakup perhitungan neraca massa, neraca energi, efisiensi termal, dan persen CO₂ yang berhasil dipisahkan. Hasil studi menunjukkan bahwa efisiensi stripper mengalami fluktuasi dengan rata-rata sebesar 90,11%, yang masih dalam batas toleransi desain. Fluktuasi ini diduga disebabkan oleh variasi kondisi operasi, akumulasi fouling, serta performa peralatan yang tidak optimal. Evaluasi ini memberikan dasar untuk optimasi operasional dan pemeliharaan yang lebih baik di masa mendatang.
