“…Kulit jengkol mengandung beberapa senyawasenyawa aktif seperti alkaloid, flavonoid, glikosida antrakinon, tannin, triterpenoid/steroid, dan saponin yang dimanfaatakan sebagai bioherbisida dan biolarvasida. Selain kandungan diatas kulit jengkol juga memiliki unsur karbon (C) sebesar 44,02% yang diyakini unsur paling penting dapat dijadikannya kulit jengkol sebagai adsorben [11] Kulit jengkol nantinya akan dijadikan arang aktif dengan variasi bahan pengaktif (KOH, urea, dan KOH+Urea) dan suhu aktivasi (600˚C, 700˚C, dan 800˚C. Penelitian ini dilakukan untuk melihat potensi arang kulit jengkol sebagai adsorben CO 2 .…”

The concentration of carbon dioxide (CO2) gas in the atmosphere continues to increase every year, mainly due to human activities such as burning fossil fuels for energy, industrial processes, and transportation. The development of CO2 gas reduction research continues to be carried out, one of which is the adsorption process using adsorbents. The research was carried out by looking at the effect of variations in activating agent and activation temperature on adsorbents as CO2 adsorbers and how N2 and pore size distribution influence CO2 adsorption. The active carbon adsorbent used comes from jengkol peel which is carbonized via the pyrolysis method. Adsorbents are made by varying the type of activating material (KOH, Urea, and KOH+urea) and activation temperature (600℃, 700℃, and 800℃). The active ingredient KOH+urea has better absorption capacity than other variations, but not too high. N2 gas does not really affect the CO2 adsorption process because it has a low N2 adsorption isotherm, so it is not worrying if the CO2 adsorption process also contains N2 in the air. Based on measurements with Belsorp-Max II, the data obtained is only specific surface area data, this is due to the small surface pores of the adsorbent. The temperature of 800℃ has a better specific surface area than other variations, this is also by the higher CO2 adsorption capacity. So it is concluded that the pore surface area influences the ability to absorb CO2. Based on the data obtained, jengkol peel charcoal is not suitable as a CO2 adsorbent because it has a low pore surface area and adsorption isotherm

“…Also, the iodine number of the NaOH activated charcoal fluctuated, while the iodine number of H2SO4 activated charcoal gradually increased as the concentration increased. The high iodine adsorption capacity was caused by the removal of chemical residues during the heating process (Pandia & Warman, 2017) and the bond formed between the adsorbent and the adsorbate which strengthen the adsorption process (Efiyanti et al, 2022). In addition, the high adsorption capacity was caused by the detachment of C and H bonding causing the carbon crystallite to either form new pores or expand the pore sizes (Rahman et al, 2020).…”

Ziziphus mauritiana is widely found in Sumbawa arid and semi-arid area. It is a drought tolerant plant which grows in areas with extreme conditions. While information of the utilisation of Bidara seeds as activated carbon is available, there are limited resources that use Bidara woods. Therefore, this study aims to characterize the activated charcoal derived from Z. mauritiana wood which was activated using 25%, 30% and 35% of H2SO4 and NaOH. The moisture content, ash content, volatile matter, fixed carbon, and iodine absorption capacity were investigated and compared to the Indonesian National Standard (SNI. 06-3730-1995). The result showed that NaOH activated charcoal obtained higher quality compared to the H2SO4 activated charcoal. The best activated charcoal was obtained from 35% of NaOH which has 1.19% moisture content, 13.21% ash content, 1.42% volatile matter, 84.73% fixed carbon, and 1892.40 mg/g iodine number. This study concludes that the characteristics of Z. mauritiana activated charcoal (except the ash content) comply with Indonesian National Standard and potentially can be developed as an adsorbent.

Uptake and release of chromium and nickel by Vetiver grass (Chrysopogon zizanioides (L.) Roberty)

et al. 2021

The effectiveness of using Vetiver grass (Chrysopogon zizanioides) in phytoremediation of wastewater has been proven. In this study, the phytoremediation potential of C. zizanioides planted in Cr- and Ni-contaminated soil was evaluated through investigating the behaviors on uptake and release of metals. Three treatments: control, Cr, and Ni, with three concentrations (50, 150, and 300 ppm), were applied. The potential of C. zizanioides is assessed by the determination of metal uptake rate, metal release rate, bioconcentration factor (BCF), biological absorption coefficient (BAC), and translocation factor (TF). The experiment showed that Cr uptake was higher than release rate and on the other hand low in uptake and release of Ni. Accumulation of Cr and Ni was 167.8 mg kg−1 and 66.3 mg kg−1, respectively. Excess of Cr in the soil was absorbed in high uptake rate making vetiver grass suitable for Cr phytoremediation. During 28-day uptake and 28-day release periods, it was found that BCF, BAC, and TF values in some treatments showed greater than 1 (one) and Ni-treated plants were able to translocate Ni to aerial plant parts supported by its high TF value. Low acidity of soil causes low solubility and low mobility of metals, resulting in low metal absorption. C. zizanioides has shown the potential as a heavy metal-tolerant species and could be potentially used as phytoremediation alternative species at least in lightly polluted areas.
