“…The band at 2850.31 cm -1 attributed to H-C-H stretching (alkyl, aliphatic), 1623.65 cm -1 corresponded to OH-fibers (water absorption), and 1414.47 cm -1 was vibrations of HCH and OCH bonds (methyl groups). In the primary sludge, there was a band at 706.52 cm -1 indicating 1 crystalline cellulose polymorph from the pulp (Risnasari et al, 2018).…”

Efforts to utilize and improve the value of pulp waste have been done by using primary sludge (still containing cellulose) and fly ash as a filler to produce composite foam polystyrene (PS)based as sound absorbent. In this study, the composite foam was produced by mixing primary sludge and fly ash with several compositions such as PS, PS/PS-g-MA/primary sludge/fly ash (80/10/10/0), (80/10/7/3), (80/10/5/5), (75/10/10/5), and (75/10/12/3). The composite was characterized based on ISO 11654:1997, mechanical properties, thermal analysis using TGA and DSC, morphology using SEM, crystallinity using XRD, and chemical analysis using FTIR. The results showed that the band at 1600.63 cm -1 was sharper due to a chemical reaction being formed between PS, primary sludge, and fly ash. The XRD analysis showed a new diffraction peak in the 2 = 21-24 o . The morphology analysis showed that primary sludge and fly ash were uniformly dispersed into PS, increasing the mechanical properties and decreasing the melting point of the PS foam composite. The sound-absorbing composite produced had qualified ISO 11654:1997 on the rating level of the sound absorption coefficient on materials for rooms with sound absorption classes D and C with the value of w 0.328-0.793.

“…The OH fiber (water absorption) was seen at 1623.65 cm -1 , and the vibrations of HCH and OCH bonds (methyl groups) appeared at 1515.47 cm -1 . In the sludge, there was also a peak at 706.52 cm -1 attributed to crystalline 1β polymorph cellulose from pulp [17]. In boiler ash aromatic ring, C=O stretching on the ketones, C=C stretching of hemicellulose, and C=C stretching of vinylidene alkenes appeared at 777.60 cm -1 , 1621.90 cm -1 , 1064.25 cm -1 , and 790.10 cm -1 , respectively [18].…”

The search for green composite for sound-absorbing material has increased a significant interest. In this study, polystyrene (PS) composite foam filled with primary sludge and boiler ash from pulp mill was produced. The product was characterized using analytical techniques such as FTIR, XRD, SEM, TGA, and DSC, while the mechanical properties and sound-absorbing coefficient were analyzed regarding ASTM D 2240 and ASTM E-1050-98, respectively. The results showed that the sludge has 1β crystalline polymorph cellulose from the pulp. The chemical reaction can be seen by the chemical bond formed during the mixing process. The peak expansion occurred at 1600.44 cm-1 indicating the presence of a C=C functional group of maleic anhydride with polymer and filler. SEM images showed that the filler was distributed and dispersed into the polymer matrix and no agglomeration was produced. The sound-absorbing composites had complied ISO 11654:1997 regarding the sound absorption coefficient rating level on materials for rooms with sound absorption classes D and C with the value of α 0.328-0.793.

“…Because OPF contains much cellulose, it is the potential to be utilized as a raw substance to make CMF or cellulose microfiber. CMF possesses characteristics including low weight, high stiffness and strength, a substantial specific surface area, and the ability to be recycled [3]. Therefore, CMF can be applied to various industries, such as the chemical, pulp, paper, cosmetics, health, and food industries [6].…”

Oil palm solid waste from Indonesia’s large oil palm plantations has enormous potential to meet various human needs. Lb. fermentum InaCC B 1295 (LFB1295) was tested in vitro for viability, acid and bile tolerance, safety assessment, and antioxidant activities as a potential probiotic. The physiochemical characteristics of oil palm frond (OPF) and cellulose microfiber (CMF) were also examined. OPF mainly consisted of carbohydrates, particularly fiber, followed by ash, protein, and fat. The major components of OPF fiber were cellulose, lignin, and hemicellulose. The crystal index of the cellulose from OPF was 93.4%, according to an X-ray diffraction examination. The vibrations that stretch the cellulose’s -OH group were discovered via FTIR analysis at 3420.05 cm-1. The viability of LFB1295 was maintained at 9.99 log CFU/g by CMF from OPF. The persistence of LFB1295 under bile-containing conditions and at low pH was characterized by a decrease in cell number at 2.03 and 1.56 log CFU/mL, respectively. Based on its ability to repel hydrogen peroxide, neutralize DPPH radicals, and actively neutralize hydroxyl radicals. LFB1295, encapsulated in CMF hydrogel of OPF, has good antioxidant characteristics. This fact is demonstrated by the value of Hydroxyl radical scavenging activity, which is 78.43%, and the capacity to scavenge DPPH radicals, which has an inhibition and IC50 of 47.28%. Encapsulated LFB1295 by CMF hydrogel from OPF passed all in vitro safety tests.
