Potential of cassava peels as a sustainable coagulant aid for institutional wastewater treatment: Characterisation, optimisation and techno-economic analysis

Penelitian ini bertujuan sebagai pengelolahan limbah organik sebagai sumber karbon. Karbon merupakan suatu material yang diproduksi dengan memanfaatkan limbah organik sehingga bermanfaat dan bernilai ekonomis. Limbah organik merupakan limbah padat yang masih dapat diolah untuk menjadi material yang bermanfaat dan bernilai ekonomis. Pada penelitian ini, karbon telah disintesis dari limbah ampas bengkuang dengan metoda kalsinasi. Proses karbonisasi dilakukan pada suhu dekomposisi termal ampas bengkuang menggunakan TGA dan karbon yang dihasilkan dikarakterisasi dengan FTIR dan mengggunakan perhitungan luas are pita vibrasi C=C dan C-O. Berdasarkan spektra FTIR, karbon yang dihasilkan dari kalsinasi ampas bengkuang pada variasi waktu dekomposisi termalnya masih mengandung komponen organik seperti yang ditunjukan oleh pita-pita serapan spektra FTIR. Hasil difraktogram menunjukan bahwa adanya vibrasi dari C=C dan C-O dari COOH pada bilangan gelombang 1300-1100 cm-1 yang menunjukkan adanya ikatan glikosida dalam pati. Pita serapan 1600-1500 cm-1 adalah vibrasi dari C=C aromatis yang menandakan keberadaan struktur cincin aromatik pada struktur karbon poliaromatik karbon ampas bengkuang hasil kalsinasi. Adanya puncak-puncak tersebut menandakan bahwa telah terjadinya pembakaran tidak sempurna yang menghasilkan carbon incomplit.

The purpose of this study was to conduct a literature review to determine the understanding of current research on the use of Cassava Peel (CP) in the field of wastewater treatment, especially as a coagulant. This study reports on the types of coagulant modification of CP, coagulants characterization of CP for each modification, coagulants performance of CP under various conditions, and various applications of CP coagulant for wastewater treatment. This literature study takes references from 51 articles from the period 2011-2022. We mapped each article used and visualized it using the VOS viewer to find out the relationship between topics and absorption capacity in terms of article titles and keywords. From the results of a literature review study, CP is an attractive option and has the potential to be used as a natural coagulant or adsorbent to remove pollutants (such as dyes and turbidity) in wastewater treatment. The results of this study are expected to provide benefits and ideas for utilizing agricultural waste such as CP to become an economically efficient material.

The present research aimed to enhance the pharmaceutically active compounds’ (PhACs’) productivity from Streptomyces SUK 25 in submerged fermentation using response surface methodology (RSM) as a tool for optimization. Besides, the characteristics and mechanism of PhACs against methicillin-resistant Staphylococcus aureus were determined. Further, the techno-economic analysis of PhACs production was estimated. The independent factors include the following: incubation time, pH, temperature, shaker rotation speed, the concentration of glucose, mannitol, and asparagine, although the responses were the dry weight of crude extracts, minimum inhibitory concentration, and inhibition zone and were determined by RSM. The PhACs were characterized using GC-MS and FTIR, while the mechanism of action was determined using gene ontology extracted from DNA microarray data. The results revealed that the best operating parameters for the dry mass crude extracts production were 8.20 mg/L, the minimum inhibitory concentrations (MIC) value was 8.00 µg/mL, and an inhibition zone of 17.60 mm was determined after 12 days, pH 7, temperature 28 °C, shaker rotation speed 120 rpm, 1 g glucose /L, 3 g mannitol/L, and 0.5 g asparagine/L with R2 coefficient value of 0.70. The GC-MS and FTIR spectra confirmed the presence of 21 PhACs, and several functional groups were detected. The gene ontology revealed that 485 genes were upregulated and nine genes were downregulated. The specific and annual operation cost of the production of PhACs was U.S. Dollar (U.S.D) 48.61 per 100 mg compared to U.S.D 164.3/100 mg of the market price, indicating that it is economically cheaper than that at the market price.
