Abstract

The magnetite nanoparticles (Fe3O4) are very promising nanomaterials to be applied as drug delivery due to their excellent superparamagnetic, biocompatibility and easily modified surface properties. Those properties are influenced by the structure and size of the material which can be controlled by studying the evolution of crystal growth. The purpose of this research is to study the evolution of crystal growth of magnetite nanoparticles in the hydrothermal system and determine the crystal growth kinetics using the Oriented Attachment Growth model. Magnetite nanoparticles were synthesized using a hydrothermal method from FeCl3, citrate, urea and polyethylene glycol at 210?C for 1 - 12 hours at a various concentration of FeCl3 (0.05 M, 0.10 M, and 0.15 M). The characterizations were conducted by X-ray Diffraction (XRD), Transmission Electron Microscope (TEM), Particle size analyzer (PSA), and Vibrating Sample Magnetometer (VSM). The XRD difractogram indicated that the magnetite was begun to form at 3.5 hours synthesis. The crystallinity and the crystal size of magnetite rose with reaction time. The diameter of magnetite crystals was in the range of 9.4-30 nm. Characterization by TEM showed that the particles were formed from a smaller particles which were then agglomerated. The PSA characterization showed that the distribution of diameter size enlarged with the enhancement of concentrations. VSM result showed that the magnetite nanoparticle has superparamagnetic properties. The magnetite crystal growth can be fitted by the Oriented Attachment Growth model with an error of 29%.

Abstract

Magnetite (Fe3O4) nanoparticles are very promising to be applied as a drug delivery system (DDS) for cancer chemotherapy. In this research, the crystal growth of hydrothermal derived magnetite particles was studied by oriented attachment (OA) model. The OA model was used to investigate the mechanism and the statistical kinetic of crystal growth. The crystal diameter change as a function of time with different concentration was measured using XRD. Firstly, 0.3248 g FeCl3 and 1.1764 g of sodium citrate, as well as 0.3604 g urea were dissolved into 40 mL of distilled water in a reactor. Subsequently, the reactor temperature was maintained at 210 °C and reaction time of 3.5–12 h in an air oven. The morphology of obtained particles was characterized using TEM, whereas VSM was used to determine the magnetic hysteresis curve. The XRD pattern showed that magnetite was obtained at temperature 210 °C and 3.5 h reaction time, as well as its intensity increased with reaction time. The crystal size of Fe3O4 was 9.44 nm at 3.5 h and appropriate with the oriented attachment model. The magnetite nanoparticles with shaped core-shell size less than 50 nm and suitable for biomedical application especially as drug delivery.

Abstract

Rotan merupakan tanaman yang banyak terdapat di Indonesia. Struktur anatomi batang rotan berhubungan erat dengan menentukan keawetan dan kekuatan rotan, antara lain  adalah besar pori dan tebalnya dinding sel serabut. Dinding sel adalah komposit serat yang terbuat dari mikro-fibril selulosa yang disisipkan ke dalam matriks hemiselulosa dan lignin. Pergantian bundel serat dan daerah berpori saluran ini lah membuat kayu sebagai bahan elektif untuk digunakan sebagai template dalam memulai persiapan pengganti tulang baru yang ditandai oleh struktur hirarkis biomimetik. Hidroksiapatit (HA) merupakan bentuk mineral dari kalsium apatit yang terbentuk secara alami dengan formula Ca10(PO4)6(OH)2. Salah satu inovasi besar dalam bidang rekonstruksi tulang adalah mengaplikasikan HA sebagai lapisan permukaan pada logam implan yang kuat secara mekanik dan dapat meningkatkan kestabilan implan pada tulang sehingga meningkatkan umur pemakaian implan logam. Pembuatan implan tulang menggunakan rotan sebagai subtitut logam dilakukan dengan bebeapa tahap yaitu pirolisis, karburisasi, oksidasi, karbonisasi dan tahap terakhir pembentukan senyawa hidroksiapatit dengan cara phospatisasi. Analisa karakteristik produk yang dihasilkan adalah dengan beberapa uji diantaranya SEM, XRD, Densitas, Porositas dan Uji Kuat Tekan.

Abstract

Sourdough bread is known to have health benefits due to its fermentation process using lactic acid and wild yeast. It can improve the taste, texture, shelf life, and nutritional content of bread as a functional food. In this study, sourdough was made from fermented papaya with varying fermentation times of 4, 5, and 6 days. The substrate was fed five times to strengthen the sourdough, resulting in a robust enough mixture to develop the dough. The resulting sourdough was used to create sourdough bread with a 30% sourdough concentration. The fermentation time impacted the quality of the sourdough, with results showing that sourdough became increasingly active as fermentation time progressed. The best sourdough was obtained from a six-day fermentation period, with a pH of 3.60 and a total plate count of 1.70 × 104 CFU/ml. The best donuts were produced using the sourdough that had been fermented for six days, with an almost perfect score of 3.9 out of 4 for all aspects, including color, aroma, taste, and texture. Using this sourdough resulted in a significantly longer shelf life; no mold appeared until the eighth day of storage at room temperature. The moisture content of the donuts was measured at 4.57%. This study demonstrates the potential benefits of using sourdough made from fermented papaya to improve the quality and shelf life of sourdough bread while also providing potential health benefits.

Abstract

The abundance of palm frond waste in Indonesia makes it an ideal source as co-firing material to increase renewable energy consumption. Therefore, it is necessary to determine whether oil palm fronds in the form of fluff, pellets, and brickets can be used as co-firing fuel. This study also aims to see whether there are differences in the potential of hard and soft palm fronds as solid fuel for power plants, as well as to calculate its slagging and fouling risk. Palm fronds was dried and reduced in sized using a wood chipper then sifted with a 20 mesh sieve to obtain palm frond fluff, then the fluff was mixed with 22% tapioca adhesive (weight ratio of 20% of the biomass) to be molded into pellet. Meanwhile, wood brickets was prepared by pyrolyzing the hard fronds (T= 550oC, t= 5 min) and mixing the charcoal obtained with 22% tapioca adhesive (weight ratio of 30% of the biomass). From the results of the analysis carried out, it is known that palm frond bricket provides the best results with an NCV value of 7095 cal/g. On the other side, both hard frond fluff and soft frond fluff contains the same sulfur content (0.06%), thus the difference in using hard or soft fronds as co-firing fuel does not have much effect. Furthermore, based on the analysis of potential slagging and fouling, all types of oil palm frond samples studied are shown to have a low to medium risk level.

Abstract

Chitin contained in shrimp shells can be used as raw material for making chitosan which is then reprocessed into nanoparticle-sized chitosan which has many benefits. This study aims to synthesize nanoparticle chitosan using the ionic gelation method and determine the effect of variations in the concentration of formic acid, sodium tripolyphosphate (TPP), chitosan, and the volume ratio of chitosan: TPP on particle characteristics, which include particle size, polydispersity index, zeta potential, particle morphology, and functional groups of particles. The first step for making nanoparticle chitosan is to make a chitosan solution using a magnetic stirrer. After that, the TPP solution at a certain volume ratio between chitosan: TPP was added to the chitosan solution. Stirring is carried out for 1 hour with a stirring speed of 1200 rpm. Furthermore, the nanoparticle chitosan was characterized by using Particle Size Analyzer (PSA), zeta potential analyzer, Scanning Electron Microscopy (SEM), and Fourier Transform Infra-Red (FTIR). The synthesis of nanoparticle chitosan using the ionic gelation method has been successfully carried out, obtaining a particle size of 464.4 nm, a polydispersity index of 0.214, a zeta potential of +0.48, and a cross-link of chitosan-TPP particles is formed.
