Published: April 2024

The purpose of this study was to explore the experience and meaning of walking in the daily lives of female elementary school teachers through self-study. In the study, my walking diarywas used as data, and it was analyzed by an inductive category analysis method. Walking in daily life strengthens positive emotions, solves various problems, serves as a communication channel with the students, and provides power for educational growth through the reflection on one’s own classes and life. In this study, a female elementary school teacher extracted theeducational meaning from her experience of walking in her personal life and the life of a teacher. Walking in daily life was helpful for the teacher’s reflecting on teaching and life, maintainingpositive relationships with the students, and resolving various conflict issues that appear during the teaching process.

Published: April 2024

The purpose of this study was to classify the conflict types among elementary and secondary teachers and to analyze the factors that influence the classification of the conflict types. Inaddition, it was analyzed whether the level of “burn-out” and “job satisfaction” among the teachers differed according to the type of the teacher conflict. For this study, latent profile analysis and multinomial logistic regression analysis were used.As a result of the study, the conflict types of teachers were derived into three latent profiles: ‘the lowest conflict group’, ‘low conflict group’, and ‘the average conflict group’. During the exploration of the predictive factors of the classification of the latent profiles, it was found that the individual factors that increased the likelihood of elementary school teachers belonging to the low-conflict group were gender, homeroom status, and intrinsic motivation. For the work environment variable, statistical significance was derived from the relationship between the work burden, teachers’ autonomy, and the relationship with other members of the staff. For the secondary school teachers, gender, the work burden, the teachers’ autonomy, their relationship with other staff members, teaching career, and temporary worker status were found to be statistically signi- ficant factors. Since the differences were assessed based on the classified latent profiles, it was found that teachers’ burnout was low and job satisfaction was high in the group with low conflict, in both groups, of elementary and secondary teachers, and there was a statistically significant difference between the groups.

Authors: Qasim Mohib A. , Atyia Thamir H.
Published: April 2024

The hardware design, implementation, and digital control method for three-phase AC induction motors based on Field-Oriented Control is discussed in this work Solar-powered water pumping systems have become an practical option for remote irrigation and water supply as renewable energy sources obtain importance. This research enhances such systems performance and dependability by employing a Voltage Source Inverter. In order to optimize the energy transfer to the water pump, the recommended approach uses the Voltage Source Inverter capabilities to transform the variable DC output of the solar panels into a controlled AC supply. The research looks at the choice of power components, control algorithms, and modulation strategies while designing the Voltage Source Inverter. The most suitable modulation strategy is determined after an in-depth review of several different approaches to ensure greater pump performance. This research clarifies on how solar energy conversion and pump control work together to provide sustainable water management in off-grid areas. The research paper "Design and implementation of VSI for Solar Water Pump Control" demonstrates how solar water pumping systems can be optimized using power electronics and control. The project addresses efficiency difficulties and operational differences to create efficient and reliable solar-powered water delivery systems, which support environmental sustainability and rural development. Based on the power of the PV panel, the P&O MPPT method calculates the submersible pump speed. The sensorless speed control method eliminates the requirement for location or speed sensors. The Black Electro-Motives Force calculates speed by estimating the flux angle in the absence of mechanical speed sensors. This method reduces costs and simplifies the system simply by eliminating the requirement for expensive and complicated speed sensors. In order to determine steady-state and dynamic performance in varying insolation conditions, a prototype 5.5 KW inverter was constructed. In conclusion up, the research provided a thorough summary of the hardware and control aspects required for Field-Oriented Control in irrigation systems. The practical outcomes of this study have the potential to spur advancements in irrigation technology and the incorporation of renewable energy, resulting in substantial gains for agricultural productivity and environmental conservation.

Published: April 2024

Sugarcane (Saccharum officinarum L.) is a plantation commodity that has an important role in the economy in Indonesia. The demand for sugar increases with the increase in population. Therefore efforts to increase sugar production by increasing the productivity of sugarcane, one of which is through the use of high quality seeds. Sugarcane Bud Chip seeds have the potential to produce sugarcane with high yields, but efforts to stimulate seedling growth really need to be increased. The use of natural Growth Regulatory Substances (PGR) from shallot extract needs to be tested on sugarcane seedlings because shallots contain the hormone auxin and vitamin B1 which are very necessary to increase the growth of sugarcane seedlings. Therefore this study aims to determine the effect of shallot extract concentration on the initial growth of sugarcane plants using the bud chip method and determine the best concentration. This study was conducted for 2.5 months and was designed using a non-factorial randomized block design with 5 concentrations of shallot extract including B0 (control/no extract); B1 (20%); B2 (40%); B3 (60%); B4 (80%). The parameters include the number of tillers, plant height, number of leaves, and root length. The results of this study indicated that the shallot extract gave a significantly different response to the growth of sugar cane seedlings, as seen in the parameters of the number of tillers, the number of leaves and root length. From the data obtained, shallot extract at a concentration of 40% was the best concentration for all parameters.

Demand for Robusta coffee is increasing every year, but this situation is not matched with the amount of its availability. This raises problems, especially those related to guaranteeing continuity of coffee quality, limited supply availability, and timeliness of sales. Therefore, this study aims to identify the structure of the Robusta coffee supply chain and analyze the efficiency of the Robusta coffee supply chain performance in Kubu Raya Regency. The method used to identify the structure of the supply chain is descriptive analysis, while the DEA method is used to analyze the efficiency of the members performance of the supply chain. The results indicate that the structure of the supply chain consists of farmers, collectors, wholesalers, and retailers. Overall, the results of the performance efficiency measurement show that the performance of the Robusta coffee supply chain is efficient. However, there are still 4 farmers and 1 trader with inefficient performance, namely DMU1,2,6, and 7 at the farmer level, while at the trader level it is in DMU 5. Therefore, improvements are needed to improve the performance of the supply chain actors by reducing the variable input and increasing the output variable

Adrenal cystic lesions are uncommon, non-functional, and asymptomatic. Adrenal Pseudocyst is a fibrous cyst devoid of any epithelial or endothelial lining. They have a female predominance with an incidence ratio of 3:1, usually occurring in the 3rd and 4th decade of life. We describe a case of a massive left-sided adrenal pseudocyst in a 50-year-old obese lady who had been experiencing stomach pain and distension for six months before her presentation. Investigations revealed a considerable cyst arising from the left adrenal gland. Excision via midline laparotomy incision was planned. Findings are discussed, including radiology, cytology, histology, and patient management. Adrenal Pseudocyst is a rare lesion, and imaging may mislead in diagnosis. Consider alternative diagnoses including benign and malignant masses of nearby organs, particularly the adrenal, kidney, and pancreas. After surgical excision, a pathological study is necessary for a conclusive diagnosis.

Objectives

We aimed to determine the variants of congenital anomalies in human fetal development using ultrasound diagnosis, its associated risk factors, and the outcome of such pregnancies.

Material and Methods

This longitudinal study was conducted at a secondary health facility in north-central Nigeria. A total of 250 consenting pregnant women between 12 and 28 weeks of gestation were recruited, and each had a detailed history taken, an ultrasound scan to screen for fetal congenital anatomic variants, packed cell volume (PCV), and a 75-g oral glucose tolerance test at 24–28 weeks of gestation. All participants were followed up until delivery, and data analysis was done with SPSS version 21.0 (Chicago, IL, USA).

Results

Ultrasound-diagnosed congenital anatomical malformations were found in 29 participants (11.6%), and all were confirmed at birth. Of the 29 cases with congenital malformation, 15 (51.7%) were males. Maternal characteristics that were significantly associated with the risk of fetal congenital anomalies included age (p < 0.001), hypertension in pregnancy (p < 0.001), ingestion of herbal medication during pregnancy (p < 0.001), previous history of unexplained neonatal death (p < 0.001), and elevated blood glucose level (p < 0.001).

Conclusion

The study shows a high incidence of congenital anomalies, especially among pregnant women with medical disorders in pregnancy. Also, there is a need to discourage the use of herbal medications during pregnancy.
Domestic Art of Viola Performance: H.A. Weickmann and V.R. Bakaleinikov
Authors: Radzetskaya Maria D.
Published: April 2024

Domestic viola art is a multifaceted phenomenon, developing along its own individual trajectory, demonstrating outstanding achievements that have had a significant impact on the world’s artistic heritage. This historical path is a testament to the boundless talent of the musicians who participated in the creation of the performing and pedagogical school — a tradition that is carefully preserved today. The musical-historical and source studies perspectives of the research proved to be the most correct for studying the work of H.A. Weickmann and V.R. Bakaleinikov, who made a notable contribution to the formation of the artistic image of the instrument, its formation in the solo and ensemble repertoire of Russian and foreign composers. The most significant here are the original works that are evidence of the authors’ growing interest in the technical and timbre characteristics of the viola and the rethinking of its role in the space of Russian musical art.

In the center of attention are personalities, ensembles, performers, and violists’ own compositions that reveal little–known facets of their work, including H.A. Weickmann’s pieces for stringed instruments published in Germany, which demonstrate the violist’s outstanding compositional skills and melodic talent. V.R. Bakaleinikov’s vocal music, which was created for famous pop singers in the early 20th century — N.V. Plevitskaya, M.A. Karinskaya, etc. — may also be of great interest. The article contains rare memoir sources published abroad and a large amount of illustrative material taken from the collections of the Russian State Library. The work of H.A. Weickmann and V.R. Bakaleinikov, for all its diversity, followed the path of forming a national tradition in which the viola took an honorable place as an instrument with great technical and sonic possibilities. This study summarizes the scattered information about the life and work of the famous violists and creates prerequisites for their further study.

Published: April 2024

Platelet concentrates (PCs) including platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) are extensively used as autologous products in regenerative medicine. In this study, the effects of different concentrations of platelet concentrate-derived lysates (PC-Ls) including PRP-derived lysate (PRP-L) and PRF-derived lysate (PRF-L) were demonstrated separately on the oocyte maturation. Since then, the effectiveness and appropriate concentration of PC-Ls will be confirmed which will be the premise for studies on improving the composition of oocyte maturation medium utilizing active components of autologous origin. The complexes of oocyte-cumulus-granulosa (COCGs) were collected from mature female mice (6-8 weeks old, Mus musculus var. Albino). The maturation medium (M-199 medium) for the COCGs was supplemented with 5%, 10%, 15% PRP-L and 5%, 10% and 15% PRF-L. Oocytes were assessed for maturity after 24 hours and 48 hours of culture through morphological (polar body appearance and developmental stage of oocyte, follicular cell morphology) and functional (in vitro fertility) evaluation. First, all groups showed the same oocyte morphology which included the first polar body. However, the development of follicular cells only happened in the groups treated with 10%, 15% PRP-L and 10%, 15% PRF-L during the culture phase. The 15% PRF-L group had the most significant proportion of mature oocytes after 24 hours of culture which was 22.88%. After 48 hours of culture, this number rose to 50.67% in the 10% PRF-L treatment group (P-value 0.05). The percentage of developed oocytes from the 10% PRF-L treatment that could be fertilized was 41.67%. The platelet concentrates-derived lysates promoted oocyte maturation independently and PRF-L supported oocyte development better than PRP-L. This study suggested a novel role for second-generation platelet concentrates (PRF) in in vitro oocyte maturation. The culture time should not be extended to 48 hours.

Published: April 2024

Due to their ability to selectively target pathogen-specific nucleic acids, CRISPR-Cas systems are increasingly being employed as diagnostic tools. “One pot” assays that combine nucleic acid amplification and CRISPR-Cas systems (NAAT–CRISPR-Cas) in a single step have emerged as one of the most popular CRISPR-Cas biosensing formats. However, operational simplicity comes at a cost, with one-pot assays typically being less sensitive than corresponding two-step NAAT–CRISPR-Cas assays and often failing to detect targets at low concentrations. It is thought that these performance reductions result from the competition between the two enzymatic processes driving the assay, namely Cas-mediated cis-cleavage and polymerase-mediated amplification of the target DNA. Herein, we describe a novel one-pot RPA–Cas12a assay that circumvents this issue by leveraging in situ complexation of the target-specific sgRNA and Cas12a to purposefully limit the concentration of active Cas12a during the early stages of the assay. Using a clinically relevant assay against a DNA target for HPV-16, we show how this in situ format reduces competition between target cleavage and amplification and engenders significant improvements in detection limit when compared to the traditional one-pot assay format, even in patient-derived samples. Finally, to gain further insight into the assay, we use experimental data to formulate a mechanistic model describing the competition between the Cas enzyme and nucleic acid amplification. These findings suggest that purposefully limiting cis-cleavage rates of Cas proteins is a viable strategy for improving the performance of one-pot NAAT–CRISPR-Cas assays.

Published: April 2024

Despite the presence of molecular hydrogen (H2) in various technical applications involving ionic liquids (ILs), its effect on the bulk and interfacial properties of ILs is poorly understood. The present study investigates the influence of dissolved H2 on the viscosity, surface tension, and phase composition of three imidazolium-based ILs by experiments and Molecular Dynamics (MD) simulations between (303 and 393) K from (0.1 to 31) MPa. The surface light scattering and pendant-drop experiments showed for all three ILs that the saturated liquid viscosity does not significantly change with increasing H2 pressure, while the surface tension decreases about 5% at 8 MPa. The MD simulations could be used to clarify microscopic origins for the behavior of the macroscopic properties. They revealed not only a compensation of compression and solvation effects due to hydrostatic pressure and dissolved H2 on the viscosity, but also a weak enrichment of H2 at the IL-gas interfaces.

Published: April 2024

Neurotransmitters are released by neuronal cells to exchange information. Resolving their spatiotemporal patterns is crucial to understand chemical neurotransmission. Here, we present a ratiometric sensor for the neurotransmitter dopamine that combines Egyptian Blue (CaCuSi4O10) nanosheets (EB-NS) and single-walled carbon nanotubes (SWCNTs). They both fluoresce in near infrared (NIR), which is beneficial due to ultra-low background and phototoxicity. (GT)10-DNA functionalized monochiral (6,5)-SWCNTs increase their fluorescence (1000 nm) in response to dopamine, while EB-NS serves as stable reference (936 nm). A robust ratiometric imaging scheme is implemented by directing these signals on two different NIR sensitive cameras. Additionally, we demonstrate stability against mechanical perturbations and image dopamine release from differentiated dopaminergic Neuro 2a cells. Therefore, this technique enables robust ratiometric and non-invasive imaging of cellular responses.
Load frequency control of multi area power system network with soft computing algorithm based controller and coordinated strategy of TCSC and battery energy storage
Authors: Ch. Naga Sai Kalyan
Published: April 2024

This work proposes the possible implementation of a water cycle algorithm (WCA) optimized controller of tilt-integral derivative plus filter (TIDF) for the load frequency control (LFC) of a multi-area multi-fuel (MAMF) interconnected power system network (IPSN). The MAMF network has two areas, and the dynamic analysis of the IPSN is assessed pertaining to the step load perturbation (SLP) of 10% in area 1. However, the performance efficacy of the TIDF is demonstrated and validated with other recent control techniques reported in the literature. The IPSN is considered with the communication time delays (CTDs) as the realistic constraint, and their subsequent impact on the LFC performance is demonstrated and vindicated. Further, the IPSN model of the MAMF system is enacted with the battery energy storage (BES) in areas 1 and 2, and the thyristor-controlled series compensator (TCSC) with the tie-line as the territory regulator. Simulation results showcased that there will be an improvement in the LFC of MAMF system performance with the employment of a territory control scheme.

Published: April 2024

One of the strategic decisions in the company is related to dividend decisions. It becomes the basis for investors to invest in shares. Investors value income from dividends distributed by companies for more than income from capital gains. Investors prefer to receive payment now than future ones because they are faced with uncertainty. Regular dividend distribution indicates the company has bright prospects in the future. Accordingly, Dividends have a significant influence on the increase in share prices. Data were collected using the documentation method of 34 samples of the most liquid Islamic stocks listed on the IDX. This research uses the SPSS analysis technique and uses a partial test (t-test). The tests to determine the significance of each independent variable in influencing the dependent variable with a one-way test and using moderation regression to test and analyze the effect of dividends per share on stock prices, whether to strengthen/weaken the dependent variable. The study results found that profitability and solvency , as well as dividends, have a relationship with stock prices. The relationship between ROA and share prices as moderated by dividends is negative for stock prices. The relationship between ROE and share price, which is moderated by dividends, is positive but not significant. Dividends can significantly strengthen the DER relationship to the share price. In addition, dividends were able to strengthen DAR's relationship with share prices significantly.JEL: G11, G12, G41

Published: April 2024

Using the stress test, we measured the Comercial banks' withstand under pressure caused by the outbreak of COVID-19, which led to a freeze of the real estate market, a fall of the stock market, and an increase of non-performing loans (NPLs). The findings show positive and hopeful signs. Even though the real estate and stock markets fell by 40%, resulting in a significant devaluation of the banks' loan collaterals, banks do not need to supplement provisions for credit risk. The high number of NPLs, which lead to increased provisioning, erodes net earnings, reducing the capital adequacy ratio (CAR). Banks can still meet both the 9% minimum CAR requirement and the 3% maximum NPL requirement. The study also identifies the maximum safety threshold of the Vietnamese banking system, which averaged up to a 50% increase in NPLs. Two of the country's top 10 banks are even able to maintain a CAR greater than 9% and an NPL ratio below 3%, although NPLs increase to 450% and 215% compared to these before the shock, respectively.JEL: E50, G21

Altering Tick Sizes, Liquidity, and Stock Return in Indonesia
Authors: Kim Sung suk
Published: April 2024

This study aimed to investigate the effect of tick-size altering on liquidity and stock return using the 2000-2018 Indonesia stock market (IDX) data. IDX was used to alter the tick size regime five times during the sample period. The results showed that a decrease in absolute tick size increases the liquidity estimated by the effective spread. The zero-return transaction frequency decreases consistently with a decrease in absolute tick size. The size also negatively impacts the abnormal stock return. Therefore, Fama-MacBeth approaches using individual firms' data show consistent results as the time series methods after controlling characteristic factors.

The COVID-19 outbreak drastically impacts the worldwide economy including the stock returns. This study uses Indonesia and Malaysia cases with a total of 141.585 and 219.381 observations in 2020. The measurement of COVID-19 of this study uses daily new confirmed cases and daily death cases from each country. To test the hypothesis, an unbalanced panel and multiple regression are used to test the crowded data. The results show different results for each country. In Indonesia, we found that the COVID-19 outbreak is a strong negative effect on stock return, in contrast, Malaysia found it to be less influence. Furthermore, the effect of Monday and Friday was used to test any impact of the day during the pandemic on stock return. Surprisingly, the effect of Friday affects different from Monday. The weekend effect still occurs in a pandemic situation and the investor mood sentiment to Indonesia’s stock market. This could be one of the aspects for investors consider when making investment decisions during a pandemic.

The results of this study indicate that the business cycle has two effects on the price-cost margin in Indonesian banking. First, GDP has no effect on the price-cost margin. Second, credit has a negative effect on price-cost margins in Indonesian banks. Our result study is to prove the results of research on "financial accelerators" in previous studies. This study suggests banks and policymakers in Indonesia must be able to assist the economy in providing credit to accelerate economic recovery, which can reduce the default risk.

Authors: Ridwan Ridwan , Diantimala Yossi , Indayani Indayani
Published: April 2024

This study aims to examine the effect of asset revaluation on the company's future performance and dividend policy through leverage as a mediating variable. Financial statements play an important role as a source of information for stakeholders in predicting the company's future performance. Stakeholder interest in dividends is limited by biased information about the company's future performance through leverage levels and asset revaluation results that can be handled through financial statements in decision making for dividend distribution. Therefore, this study supports agency theory and dividend policy theory. The sample of this research is 205 financial statements of companies listed on the Indonesia Stock Exchange for the period 2012-2019. The analytical method used is Path Analysis. The results show that an increase in asset revaluation reduces the company's level of leverage and future company performance, and an increase in the benefits of asset revaluation increases the company's dividend policy. The increase in leverage has a positive contribution to the company's performance in the future but does not have a significant effect on dividend policy due to the high level of company debt. Meanwhile, leverage does not mediate an increase in asset revaluation on future company performance and dividend policy. This study contributes to the improvement of the model to predict the company's future performance by implementing business strategies on asset revaluation and leverage.
Analysis of Capital Market Reactions To The Merger of Indonesian Sharia Banks: BRIS Stocks Evidence
Authors: Agustin Grisvia
Published: April 2024

This study aims to obtain evidence of the stock market’s reaction to the merger of Indonesian Islamic banks and its prediction power to JCI. The variables used in this study are abnormal returns and trading volume activity with an observation period of 60 days before the event and 60 days after the event. We use 2 types of time series data, which are daily data to analyze AR and trading volume activity, and weekly data to analyze the causality relationship. The results showed that there were no differences in abnormal returns before and after the merger, but there were differences in trading volume activity before and after the merger. In addition, this study also aims to determine the reciprocal relationship using Granger causality between the JCI and BRIS stocks prices before and after the merger of Indonesian Islamic banks. The results of the study show that there is no reciprocal relationship between the Composite Stocks Price Index and the stock’s price of BRIS and vice versa.
Income Diversification Strategy on Bank Stability:International Banks Evidence
Authors: Octavianus Handy , Fachrudin Khaira Amalia
Published: April 2024

This study aims to analyze the implementation of the income diversification strategy on bank stability carried out by international banks. This study uses panel data from 32 international banking companies from 2010-2019 with a total of 320 firm years of observation. The generalized method of moments is used as a statistical analysis tool for panel data. The study results show that the implementation of the income diversification strategy carried out by international banks was convincingly able to increase bank stability. This indicates that international banks were able to perform cost diversification efficiency to achieve better stability. Furthermore, the use of high leverage could reduce bank stability. This study shows robust results in the measurement of income diversification using either the Herfindahl Hirschman Index (HHI) or the ratio of non-interest income to total income. This is a premier formal assessment of the nexus between income diversification strategies and risk management among the largest commercial banks in the world context. This research is expected to be useful for banking management, regulators, and investors in the banking sector.
The Effect of COVID-19, Commodity Prices, and Exchange Rate on Indonesian Stock Market
Authors: Nurrahma Almira Intan
Published: April 2024

The purpose of this study is to examine the impact of COVID-19, exchange rate, and commodity prices on the performance of stock markets, focusing on the Arbitrage Pricing Theory (APT) and behavioral influence of the sentiment due to COVID-19. To accomplish this, search volumes compiled by Google Trends on the topic of COVID-19 were used as a proxy for COVID-19 sentiment. The results from applying a panel data approach, using a data set of 35 stocks listed LQ45 index, for the period January 1, 2020, to December 31, 2021, showed that COVID-19 cases and exchange rate have a negative effect on the stock markets. Conversely, commodity prices positively affect the stock markets. However, the estimation fails to reflect the significant impact of the COVID-19 sentiment on stock markets, but it has a positive effect on stock markets. This result implies that (1) higher COVID-19 cases are still a source of weakness in the Indonesian stock market, (2) Positive sentiment suggests that Indonesian investors are more optimistic throughout the pandemic period.
Does CSR increase cost stickiness?
Authors: Kristianti Ika , Yuyetta Etna Nur Afri
Published: April 2024

This study aims to provide evidence of corporate social responsibility (CSR) engagement with cost stickiness. Cost stickiness is an asymmetrical cost behavior in which the magnitude of the increase in costs tends to be higher when there is an increase in activity compared to the decrease in costs when there is a decrease in activity. The pattern of changes in costs depends not only on the size of the activity but also on the direction of the change. The research hypothesis states that the involvement of CSR requires the long-term commitment of the company in value creation activities, so it is difficult to suppress committed resources instantly. This study uses employee welfare costs and donations as a proxy for CSR. The research sample is a manufacturing company in Indonesia, with the observation year of 2017–2020. The results of the study prove that there is cost stickiness in selling, administrative, and general costs, and the degree of cost stickiness increases when CSR costs are added to the research model. The results also confirm that changes in activity levels and changes in costs are not always the same. These findings provide new evidence for understanding how CSR affects cost stickiness in manufacturing firms.

Published: April 2024

This study was conducted to assess the stock price index on the Indonesia Stock Exchange (IDX) which can be used as a proxy for the stock market in Indonesia. The indexes used to search for stock market proxies in Indonesia are JCI, IDX30, LQ45, IDX BUMN20, Jakarta Islamic Index (JII), KOMPAS100, MNC36, SRI-KEHATI, and PEFINDO25. The period in this study is from June 2018 to October 2021 obtained through bloomberg.com. Based on the results of the Paired Sample t-Test, the JCI returns before and during the Covid-19 pandemic did not show a difference in stock beta. Then, the results of the Standard Error Estimate (SEE) test show that JCI returns have the smallest deviation rate in the period when Covid-19 occurred and in the entire period. The results showed that the JCI return can be used as a proxy for the stock market in Indonesia compared to the returns of other stock indexes.

Authors: Hadibowono Satrio , Munandar Agus
Published: April 2024

The sample consists of 11 Islamic commercial banks with a time series from 2015 to 2020. The factors in the study are based on previous empirical literature. The findings show that the variables that have been moderated by Maqashid Shariah, such as the capital adequacy ratio and the Sharia supervisory board, are more significant than the variables of operational costs, non-performance finance, and the independent board of commissioners in influencing the profitability of Indonesian Sharia banking. The results of the study show that profitability growth, as measured by the moderation of the Islamic Maqashid variable on the capital adequacy ratio and the Sharia supervisory board, is a significant determinant of profitability, which implies that most of the profitability of Islamic banking in Indonesia is motivated by the capital adequacy ratio and the Sharia supervisory board, which is statistically significant. The coefficients of the capital adequacy ratio and Sharia supervisory board measures imply that these variables have a positive effect on the profitability of Islamic banking in Indonesia. The increase in profitability of Islamic banking in Indonesia, as measured by the capital adequacy ratio and the Sharia supervisory board, has a positive effect on profitability; these findings indicate that the growth of factors such as operational costs, non-performance finance, and the independent board of commissioners in influencing profitability of Indonesian Sharia banking is not motivating.
