Abstract

[The Potential of Sago Bark (Metroxylon sago) as Biosorbent for Adsorption of Crystal Violet Dye: Isotherm, Kinetic, Thermodynamic Studies and Its Application] Penelitian bertujuan untuk memanfaatkan limbah kulit batang sagu (Metroxylon sago) sebagai biosorben yang berbiaya rendah untuk penyerapan zat warna crystal violet. Metoda adsorpsi dengan sistem batch digunakan dalam proses optimasi dengan parameter yaitu pengaruh pH, kosentrasi awal, waktu kontak dan suhu pemanasan biosorben. Kondisi optimum diperoleh pada pH 7, konsentrasi awal 900 mg/L, waktu kontak 45 menit, dan suhu pemanasan biosorben 25°C dengan kapasitas adsorpsi sebesar 72,57 mg/g. Proses adsorpsi mengikuti model isoterm Langmuir (R2 = 0,9985) dan model kinetika orde dua semu dengan R2 = 0,9890. Studi termodinamika menunjukkan bahwa proses adsorpsiberlangsung secara spontan dan eksotermik. Siklus adsorpsi-desorpsi menggunakan asam asetat 30% didapatkan sebanyak 5 siklus. Hasil penelitian menunjukkan bahwa limbah kulit batang sagu memiliki potensi sebagai adsorben berbiaya murah, ramah lingkungan dan efisiensi yang tinggi.

Abstract

The textile industry is one sector that generates effluent containing a significant quantity of pollutants, including dyes, and thus has an effect on the environment. Synthetic dyes, which are toxic and difficult to degrade, are utilized extensively in the textile industry. Therefore, a new study utilizes banana stems as a cost-effective biosorbent to remove indigo carmine dye. This research aims to investigate the use of banana stem waste as a bisorobent in batch method to adsorption indigo carmine dye. The optimal concentration and pH values are 2 and 900 mg/L, respectively. The interaction between the indigo carmine dye and the banana stems is suggested by the FTIR analysis.  The solution's indigo carmine dye may be adsorbed by banana stem.
