Abstract

The photoelectric effect is a phenomenon where electrons are emitted from a metal surface when exposed to light of a certain frequency. Research indicates that the kinetic energy of the emitted electrons depends on the light frequency rather than its intensity. In the context of sensor technology, the photoelectric effect is utilized in various applications such as light sensors, digital cameras, and solar panels. The use of interactive simulations, such as PhET, has proven effective in enhancing students' understanding of this concept. The analysis reveals that while students' comprehension of the photoelectric effect remains low, employing educational tools like simulations can significantly aid in physics learning and its practical applications.

Abstract

Co-firing of coal and biomass in an existing coal fired power plant is being considered as a viable alternative to transition from non-renewable-to-renewable energy utilization. In this regard, various researches have been conducted in the last twenty years, in most of which the general conclusion is that the boiler efficiency decreases with respect to increasing biomass percentage in co-firing, nonetheless, additional study is deemed to be required, especially for waste biomass which are abundantly available in Indonesia. The waste biomass to be employed in this study are palm empty fruit bunch (EFB), rice husk, and wood pellet produced from sawdust. Co-firing combustion thermodynamic characteristics which are to be deployed in this study are air-to-fuel ratio (AFR), combustion CO2 emission, and adiabatic flame temperature. An open source CoolProp of thermodynamics properties formulations were implemented in order to evaluate thermodynamic properties of corresponding materials involved in this study. The results of the study show that AFR decreases with increasing biomass composition in the fuel, where the AFR rate of change per percent of biomassa are -0.018, -0.0406, and -0.026 for blend of coal-EFB, coal-rice husk, and coalwood, respectively. As to the AFR characteristic, the emission of carbon dioxide is decreasing with

Abstract

Along with the quality of service that continues to increase from year to year, it is necessary to reanalyze (evaluation) to determine the condition and readiness of the equipment to maintain continuity and the electric power system in the process of sending the electric power. To maintain the continuity and reliability of theprocess of distributing electric power in the electric power system, therefore various protection systems are needed from disturbances that may arise.20 kV distribution network on a transformer 30 MVA TFT 1 70/20 kV 30 MVA using a safety system Ground Fault Relay (GFR) that is used to detect the smallest current.. This study uses a Neutral Grounding Resistor (NGR) and solid neutral grounding system to determine the proper setting of the GFR while the single-phase short circuit to ground fault occurs and to determine the effect of relay adjustment when using a neutral grounding system by simulating ETAP 12.6. The maximum fault current of a single- phase short circuit with the direct grounding method is 1.15 kA, while the maximum fault current with the NGR grounding method is 0.235 kA. At the Bolok – Tenau III connection, the relay working time setting obtained from the solid grounding system is 0.5 s, and the relay working time setting obtained from the NGR grounding system is 0.5. In this case, the grounding method using a Neutral Grounding Resistor is more effective for neutral grounding of the transformer because it can reduce the short circuit current that occurs so that it does not endanger humans or nearby equipment.

Abstract

Practical work has been carried out on the Application of Diffraction and Light Interference Phenomena in Measuring the diameter of thin objects. This practicum aims to understand diffraction events and light interference, understand the application of interference diffraction to measure the thickness of thin objects, and find out the factors that influence diffraction events and light interference. Diffraction and interference can occur simultaneously when light passes through a narrow slit or thin object and combines to form a new light wave. This practicum uses the principle of superposition of light waves, using light as a wave so that it can create superposition phenomena and their derivatives, namely diffraction and interference. This practicum can be done by preparing tools and materials, then arranging the tools and materials according to the scheme. Then the physical parameters in this experiment were measured and recorded, namely the distance from the laser to the object, the distance from the object to the screen, and the distance created between the light patterns and the central light. The variations used are variations in thin objects, namely guitar strings and copper cables and variations in the distance of the object to the screen. From the experiments that have been carried out it can be concluded that diffraction and light interference events are the nature of light as a wave which has the principle of superposition. By applying the phenomena of diffraction and interference, the diameter of an object can be determined. From the practicum that has been carried out, data is obtained in the form of distances between orders or light-dark patterns that are formed. For variations of guitar strings, the diameter is 0.13 mm. while for the copper cable variation, the diameter is found to be 0.77 mm.

Abstract

The Doppler effect is a phenomenon of frequency shift caused by relative motion between a wave source and receiver, with significant applications in radar and telecommunication systems. This study conducts a systematic literature review to explore its utilization in these fields. In radar systems, the Doppler effect is essential for target detection, speed measurement, and classification. In telecommunication systems, it supports channel estimation, time synchronization, and interference reduction. Despite its advantages, challenges such as multipath propagation and high-speed movement require further attention to enhance system performance and reliability.

Kepler's laws are one of the most important milestones in the history of astronomy and physics, explaining the motion of planets and satellites around the sun. This research aims to analyse the existing literature on Kepler's Laws, including the First, Second and Third Laws of Motion. Through this analysis, it is expected to understand the contribution of Kepler's Laws to the development of science and technology, as well as their application in modern astronomy. The method used in this research is descriptive analysis of various relevant literature sources. The results show that Kepler's Law not only explains planetary motion, but also provides the basis for the development of Newton's theory of gravity and modern astronomy. In addition, the application of Kepler's Law in satellite technology and space missions demonstrates the relevance of this law in today's scientific and practical context.

Abstract

Thermal radiation is a fundamental phenomenon in astrophysics that plays a key role in understanding various astronomical objects and cosmic processes. In the context of astrophysics, thermal radiation is produced by celestial objects that have temperatures above absolute zero, such as stars, planets, and nebulae. The Stefan-Boltzmann Law and Wien's Law are important tools for characterizing the spectrum of radiation emitted by these objects, which depends on their temperature and material properties. The study of thermal radiation allows astronomers to estimate the temperature, chemical composition, and distance of celestial objects. For example, analysis of the spectrum of thermal radiation from stars provides information about their evolutionary stage and formation mechanisms. In addition, thermal radiation from galaxies and star clusters provides insight into the history of the formation of structures in the universe. This article reviews the basic mechanisms of thermal radiation, its applications in astronomical observations, and its impact on our understanding of cosmic evolution. With advances in telescope technology and remote sensing instruments, the study of thermal radiation will continue to make significant contributions to the exploration and understanding of the universe.
