Abstract

We study the partial thermalization to the effect of efficiency at maximum power (EMP) of a quantum Otto engine using Bose-Einstein Condensation in 3D harmonic potential. Partial thermalization occurs at a finite-time isochoric process, preventing the medium from achieving equilibrium with reservoirs, leaving it in a state of residual coherence. Under these circumstances, the performance of the engine can be seen from its power and EMP. The 3D harmonic potential is used to generate an excitation of energy during the expansion and compression. The total energy is defined by the total work done in a cycle. Using Fourier’s law in conduction, we found that power explicitly depends on the duration of heating and cooling stroke time and efficiency of the engine; that is the higher stroke time and efficiency, the less power output. In order to find EMP, we maximize power with respect to compression ratio κ, and we found that EMP also depends on the isochoric heating and cooling process. By varying the stroke time of the isochoric process, EMP slightly decreases with increasing isochoric time due to entropy production. However, adjusting cooling stroke time more extended than heating stroke time could significantly improve the EMP of Otto Engine.

Abstract

In this paper,we consider three models of quantum heat engines based on Carnot cycle using three energy levels; (1) the ground state, (2) the degenerate state, and (3) the highest energy state. We investigate the variation in the transition state by selecting three different degenerated states. The result we obtained still analogous with the classical heat engine efficiency and also the previous Quantum Carnot Engine model, which only depends on the initial width and the final width of the potential well in isothermal expansion. Moreover, the effect of transition state generally can be accepted for multistate quantum heat engines with 3D systems in cubic potential.

Abstract

This activity aims to apply Bernoulli's law to the piping system in the hydrant pump to meet the needs of residents in bathing, washing, and irrigating the fields. The activity begins with conducting a site review survey, counseling and determining the location of pump placement, making pumps and towers, and lifting pumps and towers to the location. Then the activities at the location are divided into several parts, including the manufacture of civil and mechanical pump systems and testing the success of the pump system. This activity carried out the manufacture of hydrant pumps by installing pipes using Bernoulli's law to meet the needs of the residents of Jorong Batu Gadang, totaling 30 families and irrigating rice fields covering an area of 78 ha, which are rainfed rice fields. The results of the activities carried out at Nagari Katialo, Jorong Batu Gadang in applying the concept of Bernoulli's Law to the piping system at the hydrant pump made water faster to reach the highest point of the piping system that had been made. As for the difference in height between the position of the pump and the water level in the reservoir (tank) of 30 meters, the flow of water rising to the tank is 2 liters/second. The people of Jorong Katialo can already enjoy the water stored in the reservoir. The success of this pump system is shown from less than 10 minutes of testing the water successfully to the water reservoir above the tower with a height difference of 30 meters from the placement of the hydrant pump.

Abstract

Nobita Hill is one of the areas being developed as a tourist attraction in the city of Padang. Above Nobita Hill is a beautiful view, and you can see the picture of Padang City. However, the hilly topography with steep slopes makes this area prone to landslides. This activity aims to map the potential for landslides on Novita Hill. Activities start from preparation, implementation in the field, and evaluation. Field activities are carried out in two stages. The first stage is an experiment to map the landslide potential. The second stage is socialization. The target audience for this activity is the Village Head of Jua Nan XX Village and its officials and the community around Nobita Hill. The results of the study and mapping were disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area, which was carried out on November 16, 2022. The result of tourist objects often changes land use and cover. However, mitigation of the potential for landslides in this area has never been done. Therefore, the Andalas University Physics Department team mapped the potential for landslides on Novita Hill for six months, using microseismic and geoelectric methods. This activity obtained a map of the distribution of dominant frequencies, a map of the distribution of amplification, and an identification of slip planes concerning the potential for landslides on Nobita Hill. Furthermore, the results of the mapping and mitigation efforts have been disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area. This activity was carried out well. The landslide potential distribution map obtained from this activity is input for the community and stakeholders in developing the Buki Nobita tourist attraction that is safe from disasters.

Abstract

Quantum refrigerators (QRs) are pivotal in exploring thermodynamic behavior at microscopic scales. This study investigates a quantum Otto refrigerator using a bosonic gas confined in a cubic potential, operating under finite-time thermalization. We derive key thermodynamic quantities analytically, including the coefficient of performance (COP), cooling power, entropy, and cooling rate. Additionally, we investigate how partial thermalization during the isochoric heating and cooling stages influences overall system performance. The findings reveal a trade-off between COP and cooling power, emphasizing the importance of thermalization duration. Notably, by extending the cooling time relative to heating, the COP can be significantly improved, offering a practical approach to optimizing QR performance under realistic conditions.
