Published: March 2021

Abstract
The extreme rainfall in an area makes the area vulnerable to various disasters. To reduce the risk of damage caused by floods, it is important to know the characteristics of extreme rainfall. Generally, the characteristics of extreme rainfall are described by one variable. However, most of the extreme rainfall events also need to be explained based on the return period they occur using several variables with copula approach. This study model to the characteristics of extreme rainfall with two variables, they are namely extreme rainfall intensity and extreme rainfall volume. The purpose of this study was to analyze the spatial distribution pattern of the return period from extreme rainfall in South Sulawesi. To determine the characteristics of the return period distribution in South Sulawesi, spatial analysis is carried out using the Moran’s index and the LISA index. The results of the spatial autocorrelation analysis with the Moran’s index show that there is a relationship between several return period values in South Sulawesi, with the Moran’s index value of 0.209. This means that the value of the return period in South Sulawesi has a clustered relationship pattern. Furthermore, the results of the spatial autocorrelation analysis with LISA show that there are seven sub-districts identified as having local spatial autocorrelation. The conclusion obtained from Moran’s scatterplot is that 15 sub-districts are the main concern in preventing natural disasters because extreme rainfall in these 15 sub-districts tends to occur more frequently, so that it can lead to various natural disasters.
Fast forwad Adiabatic Quantum Dynamics On Two Dimensional Dirac Equation
Authors: Setiawan I , Sugihakim R , Gunara B E 
Published: March 2021

Abstract
We study a scheme of accelerated adiabatic quantum dynamics. This scheme was originally proposed by Masuda-Nakamura. The strategy of combining two opposite idea: infinitely-large timemagnification factor and infinitely-small growth rate of adiabatic parameter was elucidated. We apply the proposed method to two dimensional system with electric field and magnetic field using two dimensional Dirac equation. We settle the quasi-adiabatic dynamics (QAD) by adding the regularization terms to the original vector potential and scalar potential and accelerate it with use of a large time-scaling factor which realizes QAD on shortened time scale. These terms multiplied by the velocity function give the counterdiabatic terms that generate the fast forward potential. The fast forward potential can accelerate the dynamics of the system from iniitial state to the final state with the same condition.

Abstract
In entering the era of the industrial revolution 4.0 which is also known as the phenomenon of disruptive innovation, a learning process is needed that leads to the formation of high-order thinking skills (HOTS). Elementary school is the earliest formal education to provide a foundation for the next education. For this reason, HOTS-based learning is also needed in elementary schools. Following the demands of the refined 2013 curriculum, learning is given in a thematic form. This study is combining thematic learning with scientific learning to build higher-order thinking skills. Because currently it is still in a pandemic period, so the learning is carried out by distance learning. To support the learning, the communicative learning media are made that can be accessed by zoom meeting and lead to higher-order thinking. The media is made using power points, which be arranged according to sub-themes, that have been determined according to the curriculum based on the stages of scientific learning by paying attention to higher-order thinking processes. Also, an evaluation tool that leads to higher-order thinking is developed. From the trial results, scientific thematic learning can be carried out online with the help of power point media, with the result that more than 70% of students get a score of more than 70. By using the mean difference test, it is evident that there is a significant increase in the average value between pretest and posttest for 4 (four) subjects.The limitation of this learning is that not all students can actively participate in online discussions.

Published: March 2021

Abstract
The removal of CO2 and H2S gas is a crucial process in the sweetening of natural gas. One of the processes for taking these gases is reactive absorption using piperazine (PZ) promoted methyl diethanolamine (MDEA) solution. The absorption process is carried out in the sieve tray column to avoid liquids distribution problems in large diameter columns. No research discusses the acid gas absorption process simulation in the MDEA-PZ system using a sieve tray column. Therefore, this research simulates the acid gas absorption process in the MDEA-PZ system using a sieve tray column with a rate based modeling approach. The development of the rate-based model is based on the Film model’s theory. The effect of the reaction on the mass transfer coefficient is expressed by the enhancement factor. The diffusion interaction of the components in the mixture is expressed by the Stefan-Maxwell equation. The research’s main objective is to observe the effect of lean amine temperature and absorber pressure on the percentage removal of CO2 and H2S. The simulation prediction results showed the highest percentage of CO2 and H2S removal when the lean amine temperature was 60°C and the absorber pressure was 35 atm.
