Abstract

We have studied the preparation of organic-inorganic hybrid polymer precursors  by  sol-gel  technique  and  their  utilization  for  nanostructured  optical components for photonic applications. The gel polymer precursors were prepared from  siloxane  modified  by  polymerizable  acrylate  groups,  which  can  be processed  further  by  photopolymerization  process.  Molecular  structure characterizations by means of the FTIR measurements indicate the conversion of C=C  bonds  into  C-C  bonds  after  photopolymerization.  This  bond  co nversion produces  high  cross-linking  between  the  organic  and  inorganic  moieties, resulting  in  thermally  stable and chemically resistant thin polymer layer which provide  unique  advantages  of  this  material  for  particular  optical/photonic applications.  By  employing  laser  interference  technique,  gratings  with periodicity between 400-1000 nm have been successfully fabricated. Application of  those  sub-micron  periodicity  of  grating  structure  as  active  elements  in optically  pumped  polymer  laser  system  and  Surface Plasmon Resonance  (SPR) based  measurement  system  have  been  also  explored.  The  experimental  results therefore  also  show  the  potential  applications  of  this  hybrid  polymer  as  a building material for micro/nano-photonics components.

Abstract

Learning science is considered to be difficult and complicated for most students since it requires high reasoning and imagination. This study aims to increase the motivation of students in Primary School to learn science using water rockets interspersed with game. The results of the research show that there is an increase in learning motivation of learners in Lesson Subject. The design of training and games connected with PAKEM shows a positive and intensive response for students. The results showed that more than 90% of the learners provide a positive response to learning.  In addition, students’ motivation and learning activities were improved during the learning process.

Abstract

This study offers a comprehensive approach that has not been widely explored, integrating PhET interactive simulations and the Phyphox sensor application to analyze the simultaneous influence of four physical parameters amplitude, frequency, dispersion angle, and pressure on the characteristics of sound waves. The integration of PhET interactive simulations and the Phyphox application enables real-time visualization and experimental data measurement through smartphone sensors. Furthermore, this research contributes new insights by exploring the dispersion angle in the context of wave direction and intensity, a topic rarely discussed in digital media-based acoustic studies. The method used is a quantitative experiment with amplitude variations from 1 to 10 and frequencies of 400 Hz, 500 Hz, and 600 Hz, measured at distances of 1 cm, 3.25 cm, and 5.5 cm. The study also includes observations of reflection and interference patterns of waves at propagation angles of 18°, 45°, and 90°, as well as an analysis of the effect of air pressure on sound intensity, with pressure varied from 0.0 atm to 1.0 atm. The results show that sound wave intensity increases with higher amplitude and frequency, in accordance with the theory that intensity is proportional to the square of the amplitude. The propagation angle influences the reflection and interference patterns, resulting in varied energy distribution. Additionally, air pressure significantly affects sound intensity, emphasizing the crucial role of the medium in sound wave propagation.

Abstract

The demand for boards continues to increase every year, while overexploitation of wood leads to environmental degradation and forest loss. On the other hand, eggshell and water hyacinth waste continues to grow without optimal utilization. This research aims to make composite boards based on eggshell waste and water hyacinth fibers and analyze the potential of ethnoscience in science learning. This research used a qualitative descriptive method with a literature and documentation study approach. The materials used in this experiment are eggshell waste, water hyacinth fiber, and polyester resin. The composite board was made by mixing water hyacinth fiber and eggshell powder as reinforcing materials and polyester resin as a binding matrix. The results showed that the resulting composite board had a solid structure with a brownish beige color and a slightly rough surface texture. The calcium carbonate content of the eggshell provides stiffness, while the water hyacinth fiber increases the flexibility of the board. Theoretically, this material has the potential to be an environmentally friendly alternative for non-structural applications. In addition, this project can also be applied in ethnoscience-based science learning to integrate physics, chemistry, and biology concepts with local wisdom.
