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

Optical fiber is a medium that spreads information in the form of light waves. The quality of the optical fiber can be determined by knowing the dispersion value of the polarization mode which is one of the characteristics of the optical fiber by using a single-mode optical fiber design simulation method using the OptiFiber software. The single-mode optical fibers used in the simulation are SMF-28, SMF-28e, SMF-28e+, SMF-28e+ LL, SMF-28 ULL. A good quality SMF for long-distance communication is an SMF that has a small PMD value.

Abstract

Terahertz radiation (THz) has interesting and effective properties in the field of biomedical imaging techniques, this is because of its ability to interact easily, is not ionized, and does not damage biological tissue. The purpose of this study was to determine the effect of THz radiation power density on temperature distribution and heat production in bovine biological tissue consisting of skin, fat, and muscle using a modeling approach. This study uses biophysical computation techniques with the Simulink-MATLAB model in the 0.1 – 1 THz frequency range, 50 – 150 mW power, and 5 – 25 mW/mm3 power density. Temperature distribution modeling is carried out in two ways, namely with different power densities and variations in the circumference of the THz radiation source. The results showed that the higher the power density used, the greater the absorbed radiation energy with increasing temperature. This causes the temperature distribution in the biological tissue to be wider and the production of heat in the tissue will increase. The results of imaging analysis of temperature distribution to depth in bovine biological tissue, show that fat tissue has less heat production compared to other tissues. The comparison of experimental data and modeling results shows an error percentage of 1.09%.

Abstract

The acceleration of the growth in the rate of oil palm seed roots is a non-chemical solution in nursery needs. Utilizing the electricity sector as an increase in germination productivity. In this case, this study examines variations in the electric field direct current 50, 100, 200, 400, 800, and 1000 V/m and the exposure of time 15, 30, 45, and 60 minutes. The results showed exposure to an electric field direct current in voltage of 100 V/m increased germination at each exposure time by 17%, 21%, 20% and 26% with exposure times of 15, 30, 45, and 60 minutes to control. However, a maximum intensity of 1000 V/m inhibits the germination process for each time of 30, 45, and 60 minutes by 8%, 9%, and 12% in the control. Exposure to direct current in electric field intensity and exposure of time affect root metabolism in the germination process.

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.

Abstract

Non-thermal Argon plasmas serve multiple functions, particularly in healthcare and industrial applications. Numerous particles of the same species exhibit varying velocities, referred to as a 'population'. The distribution function is a standard method for characterizing a population. The speed and energy distribution functions in the Maxwell-Boltzmann equation are simulated utilizing MATLAB. The density of each species was numerically calculated using the Runge-Kutta method. This research reviews various Argon species, including Ar*, Ar+, Ar(1s5), Ar(1s4), Ar(1s3), Ar(1s2), Ar, and electrons. The parameters utilized include a pressure of 10 mTorr, an Argon temperature about 400 K, and an electron temperature about 30,000 K. The maximum velocity probability density value is observed in the Ar+ species at 6.18 x 107 (m/s)-1, while the minimum value is found in electrons at 1.93 (m/s)-1. The maximum energy probability density value is observed in the Ar+ species at 2.13 x 1029 (Joule)-1, while the minimum value is found in the Ar(1s3) species at 1.40 x 1025 (Joule)-1. The time evolution of the distribution function, independent of the coordinates r, is associated with v, at t = 10-8 s. The velocity distribution function is significantly affected by the density value, while the distribution function is contingent upon the velocity.

Abstract

Teacher competency standards are indicators that can be used as a measure of teacher characteristics that are considered professionally competent. Teachers have a very strategic role in efforts to realize national development goals, especially in the field of education. However, the goal of education is to experience a decline in competency standards at the end of each year for certain subjects, especially science / Basic Physics. Therefore, this service aims to motivate educators and students at the secondary school level to raise awareness of the education process through the practice of learning science / Basic Physics using adequate equipment and materials. The proposed form of activity is in the form of teaching and learning in secondary schools throughout the Meranti Islands Regency including SMA, MAN, and MTs, and SMP levels. In addition, this activity also provides guidance on experiments and demonstration tools for science / Basic Physics teachers regarding understanding concepts from simple to complex natural phenomena through simple demonstration media for practical tools. That way, teachers are expected to be motivated and enthusiastic in the learning process with a good and comprehensive understanding of the material. So that it can increase teacher competency standards intensively to be more qualified and professional.

Abstract

Composite from oil palm midrib waste is one of the natural fiber materials that can reduce noise. Its material sample composite with gypsum was placed inside an impedance tube, which fitted with the mass of palm midrib mill, i.e., 0.1 kg, 0.15 kg, and 0.2 kg. Next, sound absorption coefficients were measured based on the two farthest ranges of the sound-receiving microphone, i.e., range A, which was 45 cm from the sample, and range B, which was 55 cm from the sample. Sound source frequencies were used, i.e., 125 Hz, 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz. This research found that the link between sound absorption coefficients and the mass differences of each sample was not significantly affected. The highest sound absorption coefficient is 0.979 in distance A for oil palm midrib sample mass of 0.15 kg, far bigger than gypsums on the same frequency (125 Hz), which is 0.29. In conclusion, sound absorption on oil palm midrib was better because it has higher sound absorption coefficients than gypsum and a minimum sound absorption coefficient standard of 0.15. In the future, oil palm midribs might be widely used as sound-absorbing materials based on their advantages.

Abstract

Local thermodynamic equilibrium is a foundational concept in plasma physics and heat transfer, describing a state where each small region of a system can be treated as if it is in thermodynamic equilibrium, even if the whole system is not. However, achieving accurately perfect thermodynamic equilibrium conditions in real-experiments is often challenging. It often struggles for understanding phenomena like excited states or specific Arrhenius-driven reactions. As a result, the advantages of plasma modeling with simplifications can sometimes overshadow the disadvantages of experiments. This study simulated the ionization process of argon plasma using the 4th order Runge-Kutta numerical method. The simulation, initiated with initial densities before the simulation is run, each of them is electrons 2.6 × 1018 m-3, neutral argon (Ar) 2.6 × 1018 m-3, positive argon ions (Ar+) 2.6 × 1018 m-3, and positive diatomic argon ions (Ar2+) 2.6 × 1018 m-3, successfully obtained reaction rate equilibrium data at the 625th iteration. The final densities observed were 2.46 × 1018 m-3 for electrons, 2.27 × 1018 m-3 for neutral argon, 6.4 × 1015 m-3 for Ar+, and 4.34 × 1017 m-3 for Ar2+. These results show the equilibrium reaction rate in argon plasma which provides information that density of electron and Ar+ species show a decreasing trend while density of Ar and Ar2+ species shows an increasing trend which are the result of ionization and recombination processes in the entire plasma system.
