Abstract

Belimbing Island Tourism Village is one of the tourist attractions located in kuok district kampar regency. Belimbing Island Tourism Village has great potential as a tourist attraction because of its natural cultural and indigenous values. Preserving and developing culture is a step that must be taken in order to maintain its cultural sustainability and can be felt by all people because cultural values are inseparable from the role of human beings as cultural beings who inherit the culture. This research aims to empower and develop the potential in Kuok Subdistrict, Kampar. The research method is descriptive qualitative. Data collection techniques using observations and interviews. Analysis is data reduction, data presentation and conclusion drawing. The results of this study are empowering and developing tourism potential in Belimbing Island is done by preserving it by studying the culture of Kuok Village through community leaders, adding to the beauty of the traditional home environment, and following community cultural activities that strengthen the sense of brotherhood.

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%.
