Abstract

Currently, computer-based simulation methods are widely used in blood flow analysis. The application of this method has been widely used in modeling blood vessels. This article presents an example of a simple blood vessel modeling to determine the velocity of blood flow to the viscosity of blood in the blood vessels. The mathematical model of human blood flow through vascular ramifications was studied using finite element analysis (FEA), which is applied to the stable two-dimensional flow of viscous fluids through various shapes. Flow through a two-dimensional model of aortic vessels, capillaries, and veins is simulated. The velocity distribution through the blood vessels is calculated. The validity of the calculation method is determined by comparing the numerical results with other results. The implementation of the Navier-Stokes equation in a vascular model using the finite element method shows that the velocity of blood flow depends on the viscosity. The higher the viscosity of the blood, the slower the rate of blood flow in the veins.

Abstract

The blood flow that carries various particles results in disturbed physical flow in the heart organ caused by speed, density, and pressure. This phenomenon is complicated resulting in a wide variety of medical problems. This research provides a mathematical technique and numerical experiment for a straightforward solution to cardiac blood flow to arteries. Finite element analysis (FEA) is used to study and construct mathematical models for human blood flow through arterial branches. Furthermore, FEA is used to simulate the steady two-dimensional flow of viscous fluids across various geometries. The results showed that the blood flow in the carotid artery branching is simulated after the velocity profiles obtained are plotted against the experimental design. The computational method's validity is evaluated by comparing the numerical experiment with the analytical results of various functions.

Abstract

The model used in this work is a two-dimensional fluid plasma model coupled with Maxwell equations at atmospheric pressure. The model was created by applying different plasma torch parameters using the finite element approach. Three separate stages of the numerical modeling were used to show how the increase in electron density increases with time. It may be inferred from the molecular ion distribution features that the torch's quartz tube's port, which is larger than the tube's center, is where the molecular ions are primarily disseminated. Reduced pressure and the calculated distance from the port to the center of the quartz tube result in a drop in the density ratio of molecular ions to electrons. The research on microwave plasma properties revealed that atmospheric pressure is important for modeling and developing plasma sources, particularly for the conversion of carbon dioxide.

Abstract

This article examines the policies aimed at protecting peat ecosystems in Indonesia and identifies gaps or challenges in controlling forest and land fires (karhutla), particularly concerning the preservation of the Hydrological Unity Policy in Riau Province, Indonesia. The peat ecosystem is a cohesive entity that encompasses various elements, influencing each other to maintain balance, stability, and productivity. The Hydrological Unity of Peat (KHG) refers to the peat ecosystem situated between rivers, between rivers and seas, and/or within swamps. The Peat Ecosystem serves multiple functions, including safeguarding water availability, conserving biodiversity, storing carbon as oxygen producers, and contributing to climate regulation. These functions are categorized into protected and cultivation functions. However, rapid development has exerted significant pressure on preserving the KHG. This study emphasizes the need for comprehensive support from all sectors of society and active community participation to effectively reduce the risk of forest and land fires.

Abstract

Metamaterials are artificial materials with the characteristics of a negative refractive index and high resonance sensitivity. Advanced engineering in metamaterials can realize great potential in combination with zinc oxide (ZnO) semiconductor materials, which can increase the efficiency of sensor technology compared to other conventional material models. This research aims to investigate the optical properties and develop an invention for a hybrid sensor media based on a split ring resonator (SRR) metamaterial structure integrated with a thin layer of ZnO. The research methodology was carried out by simulation by designing and characterizing SRR metamaterials which were designed with variations in SRR patterns, geometry, substrate materials, unit cell configurations, and variations in the thickness of the ZnO thin layer. Geometry characterization of SRR metamaterials was carried out using the Nicolson-Ross-Weir electromagnetic (EM) field function approach, specifically the optical parameters permittivity, permeability, and refractive index. They are optimizing the performance of hybrid sensor components based on metamaterials and ZnO thin films using the GHz scale EM field function approach, especially in the reflection, transmission, and absorption spectrum. Analysis of metamaterial characteristics identifies the optical properties of permittivity, permeability, and negative refractive index which are increased and optimized from the thin layer integration model 200 nm thick ZnO in the SRR metamaterial structure with a 3×3 square pattern configuration at a resonance frequency of 1.889 GHz. The performance of the hybrid sensor media provides a resonant frequency of three equal bandwidths in the frequency range 2.89 – 3.52, 5.28 – 6.54, and 7.57 – 8.46 GHz. In addition, the highest absorption spectrum of 73% is at a frequency of ~8 GHz.

Abstract

The development of telecommunication antenna technology is increasingly being considered with the need for high and practical antenna performance. The antenna technology can be realized by using the split ring resonator (SRR) metamaterial structure. SRR metamaterial is a periodic material that has minimal manufacturing dimensions and is able to work at high frequencies. The ability of this metamaterial has the potential to be implemented in microstrip antenna structures as telecommunication applications. This study aims to design, simulate and analyze the characteristics of SRR-Circle metamaterials against the frequency function and application performance as a telecommunication antenna. The process is carried out using the Computer Simulation Technology (CST) Studio Suite Software which is operated at a working frequency of 0.009 – 9 GHz. The metamaterial structure is combined from 1 – 4 SRRs in the shape of a Circle with a fixed radius of 3.5 mm. The results of this study indicate the characteristics of metamaterials with negative values in relative permittivity (ɛᵣ), relative permeability (μᵣ) and refractive index (n) with the highest values in the metamaterial structure of the combination of 4 SRR-Circles, each with values of -144.33 Farad/m, -9.29 H/m and -9.07. In its application as a telecommunications antenna, metamaterials have succeeded in improving antenna performance. The highest antenna performance was obtained in the combination structure of 4 SRR-Circles with a return loss value of -34.37 dB, and a bandwidth of 1.00 GHz at a VSWR of 6.77 – 7.77 GHz. The results of this antenna performance have the potential to be applied to telecommunications antenna technology such as satellites, radars and 5G networks.

Abstract

Teacher competency standards serve as benchmarks that can be utilised to assess the attributes deemed essential for professional competence in educators. Educators play a crucial and strategic role in the pursuit of national development objectives, particularly within the realm of education. However, the objective of education appears to be a reduction in competency standards at the conclusion of each academic year for specific subjects, particularly in the realm of science and Basic Physics. Consequently, this initiative seeks to inspire educators and students in secondary education to enhance their understanding of the educational process by engaging in the study of science, specifically Basic Physics, utilising appropriate tools and resources. The suggested mode of engagement involves the processes of instruction and education within secondary educational institutions across the Meranti Islands Regency, encompassing SMA, MAN, MTs, and SMP levels. This activity further offers insights into experiments and demonstration tools for educators in the realm of science and Basic Physics, facilitating a comprehension of concepts that range from simple to intricate natural phenomena through accessible demonstration media designed for practical application. In this manner, educators are anticipated to exhibit motivation and enthusiasm throughout the learning process, accompanied by a thorough and nuanced comprehension of the subject matter. To enhance teacher competency standards significantly, ensuring they become more qualified and professional.

Abstract

This study aims to observe the ability of a thin layer of zinc oxide (ZnO) which is applied to sensor technology. Currently, the low detection limit of the sensor is a problem in its use. Metamaterials offer resonant properties in increasing sensitivity, but their performance is still below the current high modern technology. The high engineering properties of metamaterials provide opportunities for realizing renewable metamaterials. ZnO thin layer semiconductor material as a transparent conductive oxide can provide a wide detection potential. The ability of ZnO thin films to be adapted to metamaterial sensors can be further investigated and improved for the future.

Abstract

Intravenous (IV) infusion therapy is a medical procedure that involves the insertion of fluids directly into the patient's vein using a needle/cannula. Mismanagement during infusion fluids replacement due to negligence and shortage of medical personnel and human error must be addressed promptly. Increasing in numbers of patients throughout the Covid-19 pandemic has raised the use of infusion and the error percentage in manual infusion monitoring has also escalated, as consequence, the needs of automatic-handy tools with affordable price become a concern. The infusion monitoring system used consists of three parts, namely sensing and computing, communication, and User. This device allows monitoring and visualization of IV therapy infusion for each patient in real-time, at a remote location.
