The synthesis of materials on magnetic activated carbon is concern, with a simple and environmentally friendly. research used pecan shell (Aleurites moluccana) as source. breakthrough made in this to make electrodes supercapacitors. Obtained the XRD diffractograms show graphite lattice, respectively. Also, sharp, narrow peak seen at 2θ = 26° samples spectrum, showing highly graphitized fraction. FESEM-EDX showed AC20/80 that shape particles was like plates indicating had been formed. AC80/20...
Biodegradable bioplastics provide a promising solution to mitigate environmental harm from petroleum-based plastics. This study focuses on optimizing bioplastic films made oil palm trunk starch (OPTS), using glycerol (10, 20, and 30 % v/w) as plasticizer modified with citric-acid epoxidized (CEPO). The were formed the casting method analyzed for morphology, functional groups, diffraction peaks, thermal mechanical properties, degradation time, compostability. optimal conditions achieved...
The synthesis of modified carbon dots (N-CDs) from nanocrystalline cellulose, as the source, with combination urea and ethylenediamine, nitrogen dopant agents, was successfully carried out by pyrolysis at 300 °C.The N-CDs dispersed in both ethanol distilled water generated bright blue fluorescent color under a UV lamp 365 nm wavelength 29% quantum yield value.FTIR analysis confirmed that surfaces were amine N-doped groups on ring structure data UV-VIS spectrum also showed assumption.Produced...
Graphene Oxide (GO) has been succesfully synthesized using Hummber method from graphite powder of pencil rod. The excellent solubility graphene oxide (GO)in water imparts its feasibilty as new filler for reinforcement hydrophilic biopolymers. In this research, the biocomposite film was fabricated chitosan/graphene oxide. characteristics were investigated Fourier Transform Infrared (FT-IR) and X-ray Diffraction (XRD). results XRD showed structur in 2θ, appeared at 9.0715°with interlayer...
Graphene oxide/bacterial cellulose (GO/BC) nanocomposite has been successfully carried out with in situ process agitated culture.During the process, graphene oxide was partially reduced.Interaction between bacterial and investigated by FTIR.The addition of improved thermal mechanical properties nanocomposite.This is indicated increasing residual mass from 29.41 % GO/BC 0.04 wt to 33.91 0.1 %.When compared pristine cellulose, increased tensile strength 50.5 MPa 102.7 Young's modulus 2.0 GPa...
Thermoplastic starch (TPS) is a potential candidate for green plastic or biodegradable because it renewable, cheap, translucent, and flexible.However, the mechanical properties of TPS are still not satisfactory should be enhanced by adding reinforcing agents such as Nanofiber cellulose (NFC).This research aimed to fabricate bioplastics based on thermoplastic (NFC) solvent casting technique.NFC was prepared via physicochemical pretreatment empty fruit bunches (EFB) through steam explosion...
Biodegradable bioplastics were produced from oil palm trunk starch (OPTS) using varying glycerol concentrations (10-30% v/w) as a plasticizer, modified with citric-acid epoxidized (CEPO) via solution casting. Characterizations included FT-IR, XRD, SEM, TGA, and DSC. Higher CEPO increased melting points but reduced tensile strength Young's modulus, while improving elongation at break water resistance. Significant mass reduction (30.77%) occurred day 9, after 6 weeks, composted C:N ratio of...
Photocatalysis has attracted attention, utilizing solar energy directly to catalyze chemical reactions. This research synthesized Fe2TiO5/Ag/C nanocomposites as photocatalyst material using a wet milling process and confirmed with comprehensive characterizations. Impregnation Ag/C produced crystal defects Fe2TiO5, resulting smoother amorphous surface increased area higher volume size of pores. The optical properties absorb light at 600 nm band gap 2.04 eV thus can be classified semiconductor...
Hydrogel technology can be used as a solution for indoor growing media. is three-dimensional polymer network with cross-linked hydrophilic polymers, which are capable of swelling or storing water and physiological solutions up to thousands times their dry weight, not easily soluble. To increase knowledge about ornamental plant cultivation using hydrogel media, service was carried out by partners at the Madrasah Aliyah Swasta Muhammadiyah Sidomulyo. This aims provide in form alternative...
