Abstract

This project aims to provide students with lab practice that is completely genuine, to learn about their practice habits, and to inspire them to study after utilizing the created physics lab practice. This study is a type of development utilizing physics lab practice use 4-dimensional learning tools. Utilizing confirmation of reasoning, observation, and questionnaire. The evaluation of the virtual lab yielded the logic validation value 2,78 and they are considered reliable and safe for usage as a trial for development. The development testing revealed that the students work passed muster with the help of the physics virtual laboratory baseds instructions, either on the capacity for observation and note taking or the capacity for interpretation and illustration. The results of the development test showed that the students practicum performance in all practicums, in the aspect of ability to observe and record practicum results, was in the good category with a range between 61.37% and 92.93%, and in the aspect of ability to interpret the results and formulate conclusions, it was categorized as good with a range between 65.15% and 96.97%. The virtual laboratory based physical practicum instructions that were developed obtained validity in the good category and are suitable for use as a guide for physical teachers and students in carrying out practicums.

Abstract

Mortar is one of the materials commonly used in everyday life as part of the world of civil engineering. Cement based mortar. Where cement serves as an adhesive and reinforcement. It's just that cement has drawbacks, one of which is the raw material which is quite expensive, therefore in this study the authors made sugarcane husks which are natural wastes with SiO2 content similar to cement to optimize mortar quality. In this study, bagasse was extracted by sintering at a temperature of 4000C – 6500C so that it became amorphous silica, then passed through a 100 mesh sieve before being applied to the mortar. When operating on a mortar, variations of the addition of amorphous silica and cement are used at 0wt%, 10wt%, 20wt%, 30wt%. Identification of amorphous silica forms that occur will be analyzed using XRD. The results of the analysis showed that the addition of sugarcane husk amorphous silica had an effect on the mechanical properties of the mortar because the sugarcane husk amorphous silica could fill the pores in the mortar. The results showed that the most optimal percentage was 20 wt% with a mortar porosity of 29.54%, a compressive strength of 1.633x10-2 N/mm2 and an impact strength of 2.872x10-4 J/mm2 at an additional percentage of 20wt%.

Abstract

Einstein's General Theory of Relativity has revolutionized our understanding of gravity by replacing Newtonian gravitational law, which regarded gravity as an attractive force between two masses. In GR, gravity is seen as a manifestation of the geometry of spacetime, influenced by the distribution of mass and energy. This theory successfully explains phenomena such as the bending of light by massive objects and the prediction of the existence of black holes. Meanwhile, Quantum Mechanics, rooted in the works of Max Planck, Albert Einstein, Niels Bohr, and Werner Heisenberg, reveals a microscopic world filled with probabilities and uncertainties, as well as phenomena such as wave-particle duality and Heisenberg’s uncertainty principle. While both theories have successfully explained phenomena at macroscopic and microscopic scales, the inability to unify General Relativity and Quantum Mechanics remains a major issue in theoretical physics. The fundamental differences between them, particularly regarding the nature of spacetime and determinism, create challenges in formulating a theory of quantum gravity. Various approaches, such as Loop Quantum Gravity (LQG) and string theory, aim to unify these two theories, although they still face limitations in experimental verification. Quantum cosmology also opens up space for deeper philosophical reflections on the nature of reality, spacetime, determinism, and the role of the observer in determining physical existence, leading to questions regarding the meaning and purpose of the universe itself within its underlying probabilistic and uncertain framework.
