Travertine is a non-marine carbonate rock precipitated from calcium- and bicarbonate-rich waters, commonly associated with hot springs, streams, and lakes in tectonically active regions. This study presents a systematic literature review of travertine deposit characteristics, encompassing mineralogical composition, geochemical signatures, petrographic textures, morphological types, isotopic properties, biotic–abiotic controls on formation, early diagenesis, and petrophysical implications. The synthesis indicates that travertine is predominantly composed of calcite, with aragonite forming under conditions of elevated temperature, high Mg/Ca ratios, and rapid CO₂ degassing. Travertines display exceptional textural diversity, ranging from abiotic crystalline crusts to microbially mediated fabrics such as shrub, peloidal, and stromatolitic structures. Major morphologies include fissure ridges, mounds, terraces, cascades, and slopes, strongly governed by tectonic setting, topography, hydrology, and substrate geology. Stable isotopes (δ¹³C and δ¹⁸O), strontium isotopes, trace elements, and REE patterns effectively constrain fluid provenance and distinguish thermogene from meteogene travertines. Microbial activity plays a crucial role in biomineralization, influencing precipitation rates, crystal morphology, and lamination patterns. Early diagenetic processes occurring during active deposition may significantly modify primary fabrics and geochemical signals. Travertine petrophysical properties exhibit distinctive porosity–velocity relationships, making them valuable analogues for subsurface carbonate reservoirs. This review highlights that travertines record complex interactions among physical, chemical, biological, and geological processes and hold significant value for paleoenvironmental reconstruction and carbonate reservoir studies.

This study aims to analyze the financial performance of PT Aviasi Pariwisata Indonesia (Persero), commercially known as Injourney the state-owned enterprise (BUMN) holding company for the aviation and tourism sectors during the 2021-2024 period. Performance is measured using liquidity ratios (Current Ratio, Cash Ratio), solvency ratios (Debt to Asset Ratio, Debt to Equity Ratio), activity ratios (Total Asset Turnover), and profitability ratios (Net Profit Margin, Return on Equity) compared against industry standards. This research employs a descriptive quantitative approach. The data utilized is secondary data sourced from the published financial statements of PT Aviasi Pariwisata Indonesia (Persero). The results indicate varied liquidity performance, with an average Current Ratio of 97.82% (below the 200% benchmark, categorized as poor) and a Cash Ratio of 63.03% (above 50%, categorized as good). Solvency performance is underperformed, with an average DAR of  and DER of, reflecting a high reliance on debt. Activity performance is identified as inefficient with an average TATO of 0.199 times (<2 times), while profitability remains negative on average with an NPM of and ROE of. Despite a significant upward trend in performance improvement, the company's overall financial health is considered suboptimal compared to industry standards. This condition is primarily driven by high debt burdens and low asset efficiency within the company.

Regional government financial performance is a strategic indicator for assessing the success of regional autonomy implementation, particularly in managing public finances in an effective, efficient, transparent, and accountable manner. This study aims to analyze the financial performance of the Government of West Nusa Tenggara Province (NTB) during the 2018–2022 period using a regional financial ratio analysis approach. The research employs a descriptive quantitative method utilizing secondary data obtained from the Budget Realization Reports (LRA) and the Regional Government Financial Statements (LKPD) that have been audited by the Audit Board of the Republic of Indonesia (BPK). The analysis is conducted by calculating regional financial ratios, including the financial independence ratio, the effectiveness ratio of Regional Original Revenue (PAD), the efficiency ratio of regional finances, the activity ratio (expenditure harmony), and the revenue growth ratio. The results indicate that the financial performance of the Government of West Nusa Tenggara Province has generally improved. The regional financial independence ratio falls within the participatory category with an average value of 57.81%, reflecting a gradual reduction in dependence on central government transfer revenues, particularly in 2022. The effectiveness ratio of PAD is categorized as moderately effective, with an average of 92.84%, although it fluctuates due to increases in revenue targets that were not fully matched by actual revenue realization. The regional financial efficiency ratio consistently remains in the efficient category, indicating the local government’s ability to control expenditures relative to revenues. Furthermore, the activity ratio analysis shows a shift in expenditure composition from operating expenditure toward capital expenditure, indicating an increased orientation toward development and long-term investment. The growth ratio reveals a significant increase in PAD in 2022, accompanied by a decline in transfer revenue growth.

Savings and Loan Cooperatives (KSP) play a strategic role as microfinance institutions that promote members' financial welfare through savings and loan services based on trust and togetherness. This study aims to analyze profitability as the basis for financial performance assessment of KSP Credit Union Bahtera Sejahtera Kewapante during the 2023–2025 period. The analysis focuses on three main profitability ratios—Return on Equity (ROE), Profit Margin (PM), and Assets Turnover (AT)—along with interpretation of performance trends, causal factors of fluctuations, and their implications for the cooperative's operational sustainability. The research employs a descriptive quantitative approach with data collection techniques through direct observation, documentation of financial statements for the last three years, and financial ratio analysis. Results indicate a significant decline in profitability performance: ROE decreased from 2.01% (2023) to -0.91% (2024) and slightly improved to -0.25% (2025); Profit Margin fell from 13.81% to -7.75% and -2.24%; while Assets Turnover showed a downward trend from 0.049 times to 0.039 times in 2025. All ratios remain far below ideal standards (ROE ≥10%, PM ≥20%, AT ≥1 time), indicating inefficiency in capital management, insufficient income to cover operational expenses, and low asset productivity. These conditions are caused by declining business income, rising operational costs, and weakening member economic activity. The findings confirm the critical need for optimizing productive loan disbursement, enhancing operational cost efficiency, and increasing active member participation as essential strategies to restore profitability and ensure the long-term sustainability of the cooperative.

This study aims to examine the effect of Corporate Social Responsibility (CSR) costs and financial characteristics on tax avoidance practices among publicly listed companies with the largest market capitalization in Indonesia. The study is motivated by Indonesia’s relatively low tax ratio compared to other emerging economies in the ASEAN region, which suggests the persistence of tax avoidance practices, particularly among large corporations. Grounded in legitimacy theory and agency theory, this research empirically investigates the influence of CSR costs, profitability, leverage, liquidity, activity ratio, growth ratio, and operating cash flow on tax avoidance. The research sample consists of 50 companies with the largest market capitalization listed on the Indonesia Stock Exchange over the 2020–2024 period, employing a census sampling method and unbalanced panel data. Secondary data were obtained from annual financial reports and analyzed using panel data regression techniques. Tax avoidance is measured using the Book-Tax Differences (BTD) approach, while model selection is determined through the Chow test, Hausman test, and Lagrange Multiplier test. The results indicate that, simultaneously, all independent variables have a significant effect on tax avoidance. Partially, the activity ratio has a negative effect on tax avoidance, whereas the growth ratio and operating cash flow have a positive effect on tax avoidance. Meanwhile, CSR costs, profitability, leverage, and liquidity do not show a significant effect. These findings suggest that asset utilization efficiency tends to restrain tax avoidance behavior, while corporate growth dynamics and strong operating cash flows encourage more aggressive tax management strategies. This study provides empirical evidence from an emerging market context and offers insights for tax authorities and regulators in designing more effective, risk-based tax supervision policies.

This study examines the impact of financial performance indicators—activity, solvency, and liquidity ratios—on profit growth in pulp and paper manufacturing companies listed on the Indonesian Stock Exchange from 2019 to 2024. The research focuses on how variations in Total Assets Turnover, Inventory Turnover, Fixed Assets Turnover, Debt to Equity Ratio, and Quick Ratio affect profitability, especially during periods of economic instability like the COVID-19 pandemic. The aim is to identify which financial ratios have the most significant influence on profit performance. A quantitative research method was employed, utilizing secondary data from 42 observations of seven manufacturing firms, selected through purposive sampling. Multiple linear regression analysis, supported by SPSS software, was used to test the hypotheses. The findings show that all five ratios collectively have a significant impact on profit variations, with an F-statistic of 2.568 and a significance value of 0.044. However, when tested individually, only Total Assets Turnover and Inventory Turnover showed significant effects, while Fixed Assets Turnover, Debt to Equity Ratio, and Quick Ratio did not. The coefficient of determination (R²) was 0.263, indicating that 26.3% of the variation in profit can be explained by the analyzed variables.

Thick leaf (Glochidion superbum) is a medicinal plant traditionally utilized by the community of East Panjang Island for the treatment of wounds, pain, and ulcers. This research was conducted to isolate the major compounds present in the ethyl acetate fraction of thick leaf and to assess its antioxidant activity using the DPPH method. The plant leaves were first cleaned, dried, and powdered, followed by maceration extraction using methanol, which resulted in an extract yield of 16.42%. The crude extract was fractionated by column chromatography using EtOAc and MeOH eluents with ratios of 9:1 (K1), 4:1 (K2), 1:4 (K3), and 1:9 (K4). UV–Vis spectrophotometric analysis showed an absorption peak at 288 nm, indicating the presence of phenolic compounds, identified as ferulic acid. Antioxidant testing using the DPPH method showed IC₅₀ values for fractions K1, K2, K3, and K4 of 12.981, 5.159, 9.658, and 10.971 µg/mL, respectively, with vitamin C as a positive control (3.563 µg/mL). Fraction K2 showed the strongest antioxidant activity. These results indicate that thick leaf contains ferulic acid with very strong antioxidant activity and has potential as a natural antioxidant source.

One of the business strategies used by companies to strengthen their business and reduce competition is through acquisitions. This study was conducted to determine changes in financial performance after the acquisition process, measured using liquidity, activity, solvency, and profitability ratios. The population of this study was companies that made acquisitions in 2022. The sampling technique used purposive sampling, and four companies that conducted acquisitions in 2022 and were listed on the IDX were obtained. The research period was two years before and two years after the acquisition. The hypothesis was tested with a non-parametric test using the Wilcoxon signed rank test. Based on the results of the study, it is known that of the four financial ratios, only the activity ratio had a significant difference before and after the acquisition. Meanwhile, there were no significant differences in the liquidity, solvency, and profitability ratios. This is because the impact of the acquisition process cannot be seen in the short term. It takes integration and a long time to create synergy or change after an acquisition.  

The food and beverage industry are generally known for its stability. Nevertheless, this sub-sector underwent fluctuations as a result of the COVID-19 pandemic, one of which was in its firm value. The study investigates how firm value is affected by key organizational characteristics, including financial performance, the scale of the firm, and the rate of sales growth. A firm's value is measured by its PBV (Price to Book Value). The study's measure of financial performance is a combination of Return on Equity (ROE) and the CR, DER, and TATO ratios. This study uses a quantitative approach. The study's population is composed of F&B firms publicly traded on the Indonesia Stock Exchange throughout 2019–2023. A purposive sampling technique was used to select the sample based on predefined requirements, leading to a total of 125 samples from 25 companies. Data were processed using WarpPLS version 8.0 to evaluate the research model through model fit, structural testing, and hypothesis testing. The results show that the model meets the required fit indices and has strong explanatory power. The findings reveal that profitability (ROE) and leverage (DER) have a positive and significant effect on firm value, while liquidity (CR) and sales growth exert a negative and significant effect. On the other hand, activity ratio (TATO) and firm size do not significantly influence firm value.

This study aims to examine the effect of financial ratios on financial distress in transportation and logistics sector companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2024 period. The research employed a documentation method by collecting secondary data from the companies’ financial statements within the observed period. The financial ratios analyzed include profitability, liquidity, leverage, and activity. The level of financial distress was measured using the Altman Z-Score method. The sample was selected using a purposive sampling technique, consisting of 22 companies observed over six years. Data analysis was conducted using panel data regression with the assistance of EViews 12, with the selected model being the Fixed Effect Model (FEM). The partial test results indicate that profitability, liquidity, leverage, and activity ratios do not have a significant effect on financial distress. However, the simultaneous test results show that the four variables together significantly affect financial distress. These findings suggest that financial ratios cannot serve as a single indicator in assessing a company’s financial distress. Nevertheless, when used collectively and combined with the Altman Z-Score measurement, they can provide a more accurate assessment of a company’s financial distress condition.

This study aims to analyze the financial health of PT Garuda Indonesia (Persero) Tbk during the 2019–2023 period using eight financial ratios based on the Indonesian Ministry of State-Owned Enterprises (SOEs) Decree No. KEP-100/MBU/2002. The research employed a descriptive quantitative method with secondary data derived from annual financial reports published by the Indonesia Stock Exchange (IDX) and the company’s official website. The findings reveal that Garuda Indonesia’s financial condition fluctuated, categorized as less healthy in 2019, deteriorated into unhealthy during 2020–2021 due to the Covid-19 pandemic, and showed limited recovery in 2022–2023, returning to the less healthy category. The main weaknesses were observed in profitability, liquidity, and solvency, while activity ratios remained relatively sound. This study highlights that Garuda’s financial problems were driven not only by external shocks from the pandemic but also by internal factors such as high debt burden and weak governance. The results are expected to contribute academically by enriching the literature on SOE financial health analysis in the post-pandemic context and provide practical implications for management, policymakers, and investors.

This research aimed to analyze financial statements to asses the financial performance of the credit union. The resurch used a quantitative approach using interviews and documentation techniques for data collection. The analysis method applied involves financial ratios, including liquidity ratio, proofitability ratio, and activity ratio. The result showed that the likuidity ratio calculations from 2022 to 2024 generally indicate good performance, with values ranging between 175%-200%. The solvency ratio calculations for the same period also demonstrated fairly good performance, with percentage above 80%. The profitability ratio calculation from 2022 to 2024 showed fairly good results, ranging between 50%-60%. Meanwhile, the activity ratio calculations from 2022 to 2024 revealed excellent performance, with values below 40%.

Profit growth serves as a primary benchmark for evaluating financial standing, particularly within the healthcare industry which demands elevated levels of efficiency and superior financial stewardship. As healthcare companies face increasingly competitive environments and high operational costs, the ability to generate sustainable profits becomes a critical determinant of long-term viability. This study aims to examine the impact of Return on Equity (ROE) and Total Asset Turnover (TATO) on the profit growth of healthcare companies registered on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. The research employed a quantitative approach using secondary data, with a sample of 10 companies selected through purposive sampling. Data analysis was conducted using multiple linear regression, supported by classical assumption testing, t-tests, F-tests, and the coefficient of determination (R²). The results revealed that ROE had a positive and partially significant effect on profit growth, while TATO showed a positive but not significant influence. However, when tested simultaneously, both variables demonstrated a significant relationship, with the model explaining 23.9% of the variance in profit growth. These findings suggest that profitability ratios, particularly ROE, play a more decisive role in determining financial performance in healthcare companies compared to activity ratios. The study highlights the importance for healthcare firms to optimize equity utilization in order to enhance sustainable profit growth and shareholder value.

This study aimed to determine and analyze the influence of financial ratios on profit changes in telecommunications companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. The financial ratios used in this study encompass four main groups: liquidity ratios, solvency ratios, activity ratios, and profitability ratios. This study employed a quantitative approach with an associative nature because it attempted to examine the relationship and influence between these financial variables on profit changes. The population in this study comprised all telecommunications companies listed on the IDX, while the sample selection was conducted using a purposive sampling technique with specific criteria, resulting in 15 eligible companies. The research data were then analyzed using panel data regression using EViews 12 software, with the best model selected being the Random Effect Model (REM). The results showed that simultaneously, liquidity, solvency, activity, and profitability ratios significantly influenced profit changes, thus concluding that the company's overall financial performance plays a significant role in determining the dynamics of profit generated. However, partial test results showed that the influence of each ratio was different. The solvency ratio has a significant negative effect on profit changes, indicating that the higher a company's debt level, the greater the risk of profit decline. Conversely, the profitability ratio has a significant positive effect, confirming that a company's ability to generate net profit is a major factor in increasing profit changes. Meanwhile, the liquidity ratio and activity ratio were not shown to have a significant effect on profit changes, indicating that short-term liquidity and operational efficiency are not sufficient to be the primary determinants in driving profit changes in the telecommunications sector.  

This study aims to examine the influence of financial performance ratios—namely, the liquidity ratio (Current Ratio/CR), solvency ratio (Debt to Asset Ratio/DAR), and activity ratio (Total Asset Turnover/TATO)—on the return on assets (ROA) of companies in the automotive sector listed on the Indonesia Stock Exchange (IDX) during the period 2020–2023. Employing a quantitative research approach with purposive sampling, the study focuses on automotive sector companies that met specific criteria over the observed time span. Data analysis was conducted using EViews version 13 software, and the methodology included descriptive statistics, panel data estimation, classical assumption tests, panel data regression analysis, t-tests (for partial effects), F-tests (for simultaneous effects), and coefficient of determination (R²) tests. The partial test results reveal that the liquidity ratio (CR) has a negative but statistically insignificant effect on ROA, indicating that higher liquidity does not necessarily enhance profitability. Similarly, the solvency ratio (DAR) demonstrates a negative and insignificant effect on ROA, suggesting that increased debt levels are not significantly associated with lower returns. In contrast, the activity ratio (TATO) has a positive and significant effect on ROA, implying that better asset utilization contributes positively to profitability. When tested simultaneously, the combination of CR, DAR, and TATO shows a positive and significant influence on ROA, indicating that these financial ratios collectively impact the profitability of automotive companies. These findings contribute to a deeper understanding of how internal financial indicators relate to profitability in the automotive sector and can inform management decisions and investor evaluations.

In carrying out measurements of the company's financial performance, several types of financial ratios are used, such as profitability, activity, solvency, and liquidity ratios. The purpose of the study is to provide comparative results of the company's financial performance as reviewed from the profitability, activity, solvency, and liquidity ratios before and after acquiring PT Mulia Boga Raya Tbk at PT Garuda Food Putra Putri Jaya Tbk in 2018-2023. The type of research used is quantitative descriptive research. The findings are that the Current Ratio before and after the acquisition is different, but not significant. This acquisition has an optimal impact on increasing the efficiency of the company's current asset management. The company's Debt to Equity Ratio shows the difference before and after the acquisition, but not significant. The acquisition makes a good contribution to the efficiency of the company's current asset management. Return on Equity shows the difference before and after the acquisition, but the change is not significant. The acquisition does not have a significant effect on the efficiency of using equity in generating profits. Total Asset Turn Over experiences an insignificant difference before and after the acquisition.

This study evaluated the antibacterial activity of a combination of microbial compounds from apple cider vinegar (ACV) and keji beling leaf extract against skin and wound pathogenic bacteria, namely Staphylococcus epidermidis (Gram-positive) and Pseudomonas aeruginosa (Gram-negative). ACV is produced through apple fermentation using Saccharomyces cerevisiae and Acetobacter aceti, rich in acetic acid, probiotics, and proteolytic enzymes. Keji beling leaf extract is obtained through ethanol maceration and contains flavonoids, tannins, alkaloids, saponins, terpenoids, and phytosterols—all of which have been shown to be antibacterial and antioxidant. The well diffusion method was used, with four treatments: negative control (DMSO), positive control (chloramphenicol 30µg), keji beling extract, and a combination of ACV + extract in various ratios. The results showed the largest inhibition zone in the 1:1 combination of ACV:extract, respectively 21.2±0.5mm (S. epidermidis) and 18.5±0.6mm (P. aeruginosa), much larger than the extract alone. This finding indicates significant synergism (p<0.05) between ACV and keji beling extract in stopping bacterial growth.

This study aims to analyze the role of cash flow and financial ratios in predicting financial distress in manufacturing companies listed on the Indonesia Stock Exchange for the period 2021–2023. The independent variables include cash flow, profitability, liquidity, leverage, and activity ratios, while financial distress serves as the dependent variable. This research employs logistic regression analysis with purposive sampling, resulting in a sample of 100 companies with a total of 300 observations. The findings reveal that liquidity and activity ratios have a significant negative effect on financial distress, while solvency has a significant positive impact. However, cash flow and profitability do not significantly influence financial distress. These findings highlight the importance of liquidity management and asset efficiency in reducing financial distress risk, while also indicating that high debt burdens increase the likelihood of financial distress. The study’s implications provide valuable insights for management and investors in making strategic financial decisions

This study aims to evaluate the financial performance of PT Jasa Marga (Persero) Tbk during the period 2021 to 2024 in an effort to assess the effectiveness of financial management within the infrastructure sector. The main focus of the study is to determine whether there has been an improvement in financial performance based on relevant financial indicators. The analysis was conducted using a descriptive quantitative approach based on the company’s published annual financial statements. The results indicate that, in general, PT Jasa Marga has experienced a significant improvement in financial performance over the past four years. This is reflected in improved liquidity, solvency, profitability, and activity ratios. The increase in toll revenue, as the company’s main source of income, along with profit growth and operational efficiency, serve as key indicators of the success of management strategies in addressing post-pandemic challenges and expanding national toll road projects. Additionally, improved debt management is evidenced by the declining leverage ratios year after year. These findings support the hypothesis that there has been an improvement in financial performance during the observation period.

This study aims to analyze financial statements as a tool to assess the financial performance of PT Unilever Indonesia Tbk for the period 2020–2023. Using a descriptive quantitative approach, this research calculates key financial ratios, including liquidity ratios (current ratio), solvency ratios (debt to equity ratio), activity ratios (total asset turnover), and profitability ratios (net profit margin). The results show that the current ratio experienced a declining trend from 66.09% in 2020 to 55.16% in 2023, reflecting a weakening ability of the company to meet its short-term liabilities. The debt to equity ratio increased from 315.90% in 2020 to 392.85% in 2023, indicating a high dependence on debt financing. Meanwhile, the total asset turnover improved from 315.90% in 2020 to 392.85% in 2023, suggesting better efficiency in utilizing assets to generate sales. However, the net profit margin declined from 16.42% in 2020 to 12.26% in 2023, signaling a decrease in the company's effectiveness in converting sales into net profit. Based on these findings, PT Unilever Indonesia Tbk is advised to enhance the management of current assets, strengthen its capital structure by reducing reliance on debt, and thoroughly evaluate cost control and marketing strategies to improve profitability and ensure business sustainability in the future.
