“…In Table 1, the value of the carbon content bound to the palm fronds before carbonization, after carbonization, and after sintering increased, respectively, to 21.63%, 75.09% and 77.35%. The fixed carbon value was affected by the ash and volatile matter content; the higher the value of the volatile matter and the ash content, the lower the bonded carbon value became and vice versa [25]. This shows the potential of nipa fronds as raw material for activated carbon.…”

Nipa palm is one of the non-wood plants rich in lignocellulosic content. In this study, palm fronds were converted into activated carbon, and their physical, chemical, and morphological properties were characterized. The resulting activated carbon was then applied as an adsorbent of Fe metal in peat water. The carbonization process was carried out for 60 min, followed by sintering at 400°C for 5 h with a particle size of 200 mesh. KOH and H 3 PO 4 were used in the chemical activation process for 24 h. KOH-activated carbon contained 6.13% of moisture, 4.55% of ash, 17.02% of volatile matter, and 78.84% of fixed carbon, while its Fe reduction efficiency was 28.09%. The H 3 PO 4 -activated carbon contained 4.67% of moisture, 2.84% of ash, 16.41% of volatile matter, and 80.57% of bonded carbon, and the Fe reduction efficiency was 52.25%. KOH-activated carbon and H 3 PO 4 -activated carbon contained fixed carbon of 78.84% and 80.57%, respectively, while their average rates of efficiency of Fe reduction were 22.82% and 39.23%, respectively. Overall, the characteristics of activated nipa carbon met the Indonesian standards (SNI No. 06-3730-1995). However, H 3 PO 4 -activated carbon was found to be better at adsorbing Fe metal from peat water.

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.

“…For many years, the water chesnut has been used by local community just for making mats (Asikin & Thamrin, 2012). Several studies have done for the possible potential of water chesnut such as biofilter (Prihatini et al, 2011), heavy metal absorber (Asikin & Thamrin, 2012), activated carbon (Suryajaya et al, 2020), and cement board composite material . Alkalizing treatment is the most common and best method in processing natural fibers to be used as a composite reinforcement material to improve the mechanical, physical and chemical properties of the fiber.…”

This preliminary research used long microfiber from water chesnut (Eleocharis dulcis) which is a weed plant in South Kalimantan, as a composite reinforcement material. This study aimed to study the effect of 6% NaOH alkalizing treatment and ultra-sonication on the properties of a long microfiber of water chesnut, especially for their chemical, physical, and mechanical properties. Firstly, the fiber of water chesnut was alkalizing by NaOH. This 6% NaOH treatment has reduced the moisture content of the fibers and their chemical components (lignin, hemicellulose, and cellulose) while the density and tensile strength of the fibers were increased. The process continued by bleaching and ultra-sonication the fiber to create a long microfiber. The water content of fibers after alkalizing treatment and ultra-sonication has met the SNI standard. Alkalizing treatment reduced the fiber size by 373.05 µm, and in the form of microfiber, before ultra-sonication was 4.28-5.96 µm and after ultra-sonication was 3.17-4.00 µm. The tensile strength of long microfiber could not measure but after alkalized, it increased significantly, from 354.25 to 3,282.10 MPa. Therefore, it is recommended that this long water chesnut microfiber is very good when used as a reinforcing material in the manufacture of composites because it will blend better with the matrix.
