Abstract

Finding out whether it is possible to use props to measure air temperature, humidity, pressure, and wind speed, determining how students respond to these variables, and determining whether high school students have mastered the science process skills (KPS) associated with these variables are the goals of this study. Three experts evaluated an expert validation questionnaire to determine the viability of instructional aids. 36 high school students in the X grade were given student response questionnaires to complete in order to gather their opinions on the instructional aids. Three observers evaluated an observation sheet to determine the students' level of KPS proficiency. Research and development (RD) using the ADDIE model is the methodology used in this study. Electronic parts such an LCD, BME280 sensor, anemometer sensor, and ESP32 microcontroller were used to create the props. The main focus of tool development is the microcontroller. Temperature, humidity, and air pressure are all measured by the BME280 sensor. The anemometer sensor is used to measure wind speed. An LCD displays the sensor measurement data.The findings show that: (1) the produced props' feasibility falls into the practicable category, with an average percentage value of 93.1%. (2) With an average percentage value of 87%, students' replies to the developed results fall into the very good category. (3) With an average percentage score of 93%, KPS mastery falls into the excellent category. These results lend credence to the idea that high school students can learn KPS using the air temperature, humidity, pressure, and velocity monitoring props.

Abstract

Quantum computers have data in the form of quantum bits (qubits), which are 0 and 1 simultaneously. This 0 and 1 state is the electron spin state on the quantum computer, namely spin up and spin down. Qubits are very sensitive to environmental disturbances, so it is necessary to accelerate the adiabatic dynamics so that the system's coherence is not disturbed by environmental interactions. These spin dynamics can be accelerated using the fast forward method, which uses an additional phase to drive the spin adiabatically. The adiabatic state is a state where the dynamics of a system have the same characteristics as the initial state after the dynamics take place. This research was conducted by qualitatively reviewing physical theory and conducting literature studies on previous research on the fast-forward method and the Landau-Majorana-Zener system. The results of this study obtained wave function solutions, regularization terms, and additional Hamiltonians in the Landau-Majorana-Zener system to accelerate adiabatic spin dynamics so that spin dynamics on quantum computers are not disturbed by the environment. After adding additional Hamiltonian adiabatic dynamics in the Landau-Majorana Zener system can be maintained but requires considerable energy. The magnetic field needed to create the same graph as the wave function graph before adding Hamiltonian, B0 = 100 Tesla. The energy required to accelerate the adiabatic spin dynamics is large, so the cost is also quite large. Therefore, efforts are needed to minimize the energy required to accelerate the adiabatic spin dynamics.

Abstract

This study aims to evaluate land subsidence based on the results of Cone Penetration Test (CPT) and Pile Driving Analyzer (PDA) tests in the construction project of Sultan Suriansyah Hospital, Banjarmasin. CPT data is used to predict soil bearing capacity and soil layer properties based on qc and fs parameters. Meanwhile, PDA is used to assess the actual bearing capacity of the pole and the actual post-piling decrease. The results showed that the carrying capacity of the mast ranged from 133 to 143 tons with a decrease of 18.0 to 19.4 mm. Meanwhile, the prediction of a decrease based on CPT with the Vesic method is ±9.58 mm. These results were further compared and validated with laboratory data and direct shear test results.
