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...
ABSTRACT Superabsorbent polymers (SAPs) can absorb and retain water thousands fold their weight, so it is believed overcome depletion issues. However, the applications are dominantly found in daily consumer goods, while still limited especially agricultural environmental sectors. This review aims to provide insights into preparation, synthesis, key properties, recent applications, challenges of SAPs targeted support sustainability. The resources for synthesis cellulose, chitin, chitosan (as...
The main objective of this research is to improve the quality bio-oil from combusting palm fronds by integrating HDPE plastic waste through a co-pyrolysis process using metal oxides (copper, zinc, iron, and cobalt) based on mordenite (MOR) zeolite. Catalyst characterization revealed alterations in physisorption properties acidity post-metal oxide addition. Fe2O3/MOR exhibits notable gasoline selectivity (36.81%), while CoO/MOR enhances kerosene (29.05%) diesel (29.95%) fractions. Both...
Abstract Glass microspheres are gaining attention in bone tissue engineering due to their ability convert into hydroxyapatite-like materials, resembling the inorganic mineral of natural bone. The morphology glass as starting material has been considered influence conversion rate and resulting product where porous could promote faster hydroxyapatite than solid microspheres. This paper reports on manufacturing (solid porous) using a flame spheroidisation process. effect various gas ratios...
This article reports the use of carbon dots (C-dots) derived from rice husk that was composited with MnO 2 to be applied as supercapacitor electrodes. Carbon were synthesized by acid hydrolysis method addition nitrogen doping. produced well dispersed in water and show a blue-green emission under UV light exposure. Spectra fluorescence taken using violet laser (405 nm) excitation source resulted broad spectra peak wavelength at 497 nm. The average particle size (APS) measured analyzer (PSA)...
The aim of this study was to evaluate the effect nanohydroxyapatite (nanoHAP) and Curcuma aeruginosa (C. aeruginosa) toothpastes on tooth remineralization antibacterial/antibiofilm activity. Remineralization evaluated by morphological changes in extracted human premolar teeth following toothpaste application. antibacterial antibiofilm activities were agar diffusion microdilution methods, respectively, against S. mutans. Statistical approach utilized formulate 20 with different concentration...
In this study, 3D porous multicomponent bioceramic scaffolds were fabricated. Hydroxyapatite (HA) and carbonate-substituted hydroxyapatite (CHA) synthesized from Asian moon scallop shell (Amusium pleuronectes) served as the bioceramics, whereas alginate chitosan polymeric components. The study was focused on determining whether presence of polyvinyl alcohol (PVA) in scaffold exerted an impact. When PVA not included, morphological examination revealed that samples exhibited structures...
The main objective of this research is to improve the quality bio-oil from combusting palm fronds by integrating HDPE plastic waste through co-pyrolysis process using metal oxides (Cu, Zn, Fe, Co) based on mordenite zeolite. catalyst was characterized XRD, XPS, TEM, SEM-EDX Mapping, SAA, and NH3-TPD. Bio-oil GC-MS CHN analyzer. product obtained showed an improvement in physicochemical properties including increase heating value, a decrease oxygenate components acidity. presence resulted...
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...
Cows and pigs are the major contributors to production of gelatin, but ethical, religious, environmental, health concerns prompting exploration gelatin sources from other materials. In study, has been isolated bones Peking duck (Anas platyrhynchos domestica) by altering citric acid concentration in pre-treatment process. This study aims identify functional groups present products derived assess effect on properties gelatin. The process was conducted soaking 11, 13, 15% for 72 h. Distilled...
Abstract In this study, the synthesis of composite biomaterials consisting hydroxyapatite (HA)/carbonated (CHA) with polymeric porous scaffolds is reported. Multicomponent biodegradable polymers were applied as scaffold. These consist alginate and chitosan. The effect polyvinyl alcohol (PVA) involvement in multicomponent scaffold was also investigated. loaded HA/CHA, bone graft materials, at various compositions. Asian moon scallop shell ( Amusium pleuronectes ) used a calcium biogenic...
Metal implant coating engineering is needed to improve the surface biocompatibility properties of metals. For this, metal surfaces with bioactive and biocompatible biomaterials will be an option. Having high as well similarity in chemical properties, nanohydroxyapatite may a candidate for implant. The key success plating formation pores which increase bioactivity In this study, was used coated on stainless steel type 316L (SS316L). To ensure that works properly surface, appropriate measure...
Beton Self Concrete Composite (SCC), memiliki sifat alir (flowable) sehingga dapat mengisi seluruh rongga beton tanpa melalui proses pemadatan dengan vibrator. Pemakaian SCC biasanya dilakukan pada struktur yang tulangan-tulangan rapat, dimana alat vibrator tidak digunakan untuk menggetarkan dan mengeluarkan udara terjebak didalam beton.
