This study analyzes the practice of staple food price manipulation at Cik Puan Market in Pekanbaru, which is alleged to be carried out by a group of traders through stockpiling, supply coordination, and price regulation that could potentially cause market distortions. This phenomenon has led to unreasonable price increases in strategic commodities such as chili, onions, rice, cooking oil, and chicken, thereby negatively affecting consumers and regional economic stability. This research uses a normative juridical approach with descriptive qualitative analysis methods, supported by empirical data from local government reports, official news, and findings from trade department supervision. The results of the study indicate that these price manipulation practices are in violation of Articles 5, 11, and 19 of Law No. 5 of 1999 about Consumer Protection. This study emphasizes that the weak supervision of the supply chain in traditional markets, as well as the minimal coordination between agencies, causes price manipulation practices to continue repeatedly. It is necessary to strengthen law enforcement, ensure transparency in the distribution of basic necessities, and enhance the role of local governments and the KPPU in order to create stable, competitive, and fair prices for the public.

This study aims to analyze the capital market reaction to the groundbreaking event of the new capital city (IKN) on the stock prices of property and construction sector companies listed on the Indonesia Stock Exchange (IDX). This research employs a quantitative approach using the event study method with an observation period of 11 days, consisting of 5 days before (t-5), the event day (t), and 5 days after (t+5) the event. The sample includes property and construction sector companies that were actively traded during the observation period. Data analysis was conducted using the Paired Sample t-test through SPSS to examine differences in Abnormal Return (AR), Cumulative Abnormal Return (CAR), and Trading Volume Activity (TVA) before and after the event. The results show that there is no significant difference in AR and TVA, but there is a significant difference in CAR, indicating that the market reacted cumulatively to the groundbreaking IKN information. These findings support the semi-strong form of market efficiency theory, suggesting that the market requires time to fully reflect information into stock prices.

This research investigates the application of the Economic Order Quantity (EOQ) method to improve drug inventory management in a primary hospital pharmacy, with a particular focus on reducing storage costs. A descriptive quantitative approach was applied using secondary data from January to December 2024, covering annual demand, purchase price, ordering cost, and holding cost. The analysis concentrated on fast-moving vital essential and moderate vital drugs that are critical for sustaining patient treatment. The study revealed inefficiencies in the hospital's procurement practices, with some medicines simultaneously facing overstock and stockout risks, indicating weak planning. EOQ calculations provided alternative procurement quantities that were smaller but more frequent, resulting in lower storage costs and better stock control. Simulation outcomes demonstrated notable cost savings, particularly for Flamicort, Diazepam, and Ventolin. These findings emphasize the value of integrating EOQ into hospital pharmaceutical logistics to reduce financial losses, strengthen supply chain efficiency, and ensure the continuous availability of essential medicines in primary hospital settings.

Firm value reflects investors’ perception of a company’s success, which is generally measured through its stock price. To enhance firm value, companies are required to manage their operations with integrity, efficiency, and professionalism, while safeguarding stakeholders’ interests through the implementation of Good Corporate Governance (GCG). GCG establishes a framework governing the relationships among shareholders, management, creditors, and the government in relation to their respective rights and responsibilities. In addition to GCG, environmental performance also plays an important role in influencing firm value. Effective corporate management should therefore align with the three dimensions of the Triple Bottom Line framework: profit, people, and planet. This study aims to obtain empirical evidence on the effect of Good Corporate Governance implementation and environmental performance on firm value. The research was conducted on manufacturing companies listed on the Indonesia Stock Exchange (IDX) during the 2021–2024 period. A total of 41 companies were selected as samples using the purposive sampling method. Data were collected from the official IDX website (www.idx.id) and the respective companies’ official websites. The data were analyzed using multiple linear regression analysis. The results indicate that the independent board of commissioners, board of directors, and environmental performance have a positive and significant effect on firm value. However, the audit committee does not have a significant effect on firm value.

This study aims to analyze the reaction of the Indonesian capital market to the establishment of the Danantara Investment Management Agency (BPI) as a new financial institution formed by the government in 2025. Using a quantitative approach through the event study method, this study measures the abnormal return of the Composite Stock Price Index (JCI) around the date of the announcement of Danantara's establishment, namely in the observation period from January 31 to April 17, 2025. The analysis results show that the market reacted significantly negatively on the day of the announcement (t₀) with an abnormal return of -0.78 percent and a p-value of 0.05, while on other days around the event, no significant reaction was found. This indicates that the market responds quickly to public information, but the impact is temporary. In the long term, the cumulative abnormal return (CAR) shows a significant negative trend, reflecting market pressure and investor caution regarding Danantara's existence. These findings are in line with the semi-strong form of market efficiency theory and show that investor confidence is highly dependent on the transparency and governance of state financial institutions. Overall, the results of this study confirm that the establishment of Danantara has not had a sustainable positive impact on the Indonesian capital market.

This study examines the stock market reaction to the Christmas and New Year holidays by analyzing abnormal return and trading volume activity for companies consistently listed in the LQ45 Index during 2021–2023. Using a quantitative causal approach and an event study design, the research observes market behavior within a 10 day estimation window and a 10 8day event window surrounding the holiday period. The findings show that abnormal return exhibits limited but notable reactions, with a significant decline observed before the holiday, indicating that investors tend to reduce risk exposure prior to market closure. After the holiday, significant movements still appear, but they remain negative, suggesting that investor activity and confidence have not fully recovered. In contrast, trading volume activity does not show significant differences either before or after the holiday, implying that changes in prices are influenced more by sentiment and price adjustments rather than shifts in trading intensity. These results indicate that the Indonesian capital market demonstrates characteristics of a semi-strong form efficiency, where public information such as national holidays is largely anticipated and absorbed by the market.

This study evaluated drug inventory management in a primary hospital pharmacy using the Economic Order Quantity (EOQ) method. A descriptive quantitative design was applied with secondary data collected from January to December 2024, covering annual demand, purchase price, ordering cost, and holding cost. The analysis revealed inefficiencies, as several drugs simultaneously faced overstock and stock out risks, indicating weaknesses in procurement planning. EOQ calculations suggested lower and more frequent procurement, reducing storage costs and improving stock control. The findings demonstrated that applying EOQ could minimize financial risks, optimize resource allocation, and ensure continuous access to essential medicines. This research highlights the relevance of structured inventory models in supporting hospital efficiency and sustainable pharmaceutical logistics, particularly in resource-limited primary hospitals.

This study aims to examine how profits and company size affect tax avoidance in energy companies listed on the stock exchange between 2022 and 2024. This study applies a quantitative approach using secondary data from annual financial reports. The population data was taken from 18 energy companies listed on the Indonesia Stock Exchange, while the sample selection was conducted using purposive sampling. The main phenomenon affecting the test results is the existence of incentives for highly profitable companies to engage in tax avoidance due to the potential for more significant tax savings. In addition, large companies usually have more resources and complex organizational structures, which give them more opportunities to carry out innovative and aggressive tax planning. It is hoped that this study can offer a fresh understanding of tax avoidance practices in the energy sector in Indonesia. The impact of this study is important for authorities to understand the relationship between corporate profitability, entity size, and tax avoidance practices, especially in the energy sector, which plays a strategic role. This understanding can assist in formulating more appropriate taxation policies to maintain economic stability and fiscal justice. The novelty of this research lies in its focus on business entities in the energy sector listed on the Stock Exchange from 2022 to 2024, which is a dynamic period marked by global commodity price fluctuations, changes in energy policy, and significant geopolitical challenges.

This study analyzes the effect of financial ratios, namely Debt to Equity Ratio (DER), Current Ratio (CR), and Return on Assets (ROA), on stock price volatility in technology companies listed on the Indonesia Stock Exchange (IDX) for the period 2022-2024. Using a quantitative approach and secondary data from annual financial reports on the website www.idx.co.id, this study purposively selected a sample of technology companies that met the data completeness criteria. This study found that a high DER increases stock price volatility due to financial risk, while a high CR and ROA reduce stock price volatility by indicating good liquidity and profitability. This study concludes that financial ratios play an important role in predicting and managing investment risk in the technology sector. Therefore, financial ratio analysis is an important tool in risk mitigation and making more prudent investment decisions in the technology sector for companies listed on the Indonesia Stock Exchange (IDX). Multiple linear regression analysis is the analysis technique used in this study, and the analysis tool used is IBM SPSS Statistics 25. The technology sector listed on the IDX for the 2022-2024 period is the population in this study, and the number of samples collected is 73 data obtained using purposive sampling.

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.

The rapid development of Islamic banking in Indonesia faces significant challenges in maintaining liquidity and profitability amidst dynamic capital market conditions. The urgency of this study arises from the need to examine whether traditional financial ratios, such as the Financing to Deposit Ratio (FDR) and Return on Equity (ROE), play a decisive role in influencing investment decisions, which are proxied by the Price to Earning Ratio (PER). The main objective of this research is to empirically test the effect of liquidity and profitability, both partially and simultaneously, on investment decisions in Islamic commercial banks listed on the Indonesia Stock Exchange during the 2021–2025 period. This study adopts an associative design with a quantitative approach, utilizing secondary data from financial reports obtained from the IDX, and analyzed using multiple linear regression on 68 observation samples. The findings reveal that neither liquidity nor profitability significantly influence investment decisions, either partially or simultaneously. These results suggest that investors in the Islamic banking sector tend to prioritize non-financial factors such as sharia compliance, governance, macroeconomic conditions, and ESG trends, rather than conventional financial indicators. In conclusion, this research extends the understanding of the limitations of Signaling Theory in the sharia context and recommends the development of a more holistic investment evaluation model. Future studies are encouraged to incorporate non-financial variables for a more comprehensive analysis.

This study investigates the impact of Environmental, Social, and Governance (ESG) Risk Ratings on stock prices of companies listed in the ESG Leaders Index on the Indonesia Stock Exchange during the period 2020–2023. Using the Ohlson (1995) valuation model as the theoretical framework, the research examines the value relevance of financial information—proxied by Book Value per Share (BVPS) and Earnings per Share (EPS)—and non-financial information in the form of ESG risk ratings. The study employs purposive sampling, resulting in an unbalanced panel dataset of 120 firm-year observations. Panel regression analysis with the Random Effect Model (REM) is applied, supported by classical assumption tests and sensitivity analysis. The findings reveal that BVPS has a positive and significant effect on stock prices, highlighting its role as a stable and value-relevant measure for investors. By contrast, EPS shows a positive but insignificant relationship, confirming the declining relevance of earnings in the Indonesian market. Moreover, ESG Risk Ratings exhibit a negative but statistically insignificant effect, suggesting that while firms with higher ESG risks tend to be valued lower, sustainability considerations are not yet consistently incorporated into equity valuation by Indonesian investors. These results imply that financial fundamentals, particularly BVPS, remain the dominant factor in stock price determination, whereas ESG information has not yet achieved value relevance in the Indonesian context. The study underscores the need for stronger regulatory enforcement, standardized ESG disclosure, and greater investor awareness to enhance the integration of sustainability risks into capital market decision-making.

This study aims to analyze the effect of profitability, leverage, and dividend policy on firm value in the energy sector listed on the Indonesia Stock Exchange (IDX) for the 2021–2024 period. The energy sector was selected due to its strategic role in the national economy and its contribution to the Composite Stock Price Index (IHSG). Out of 81 energy sector firms, 22 firms were obtained as samples using a purposive sampling method. Data analysis was conducted using the path analysis technique. The results show that profitability has a significant effect on firm value, while leverage has no effect. Dividend policy also has no effect on firm value, whereas profitability has no effect on dividend policy, and leverage has a significant negative effect on dividend policy. Furthermore, dividend policy is unable to mediate the relationship between profitability and leverage with firm value. These findings imply that firm value is more influenced by profitability factors than by leverage or dividend policy. The results of this study are expected to serve as a reference for firm management, investors, and policymakers in making future financial decisions.

This study aims to examine various factors that influence customers' engagement in choosing the Cicil Emas product as a form of long-term investment at Bank Muamalat Purwokerto. This research is based on the increasing trend of gold investment in the community caused by the increase in gold prices and awareness of the importance of halal investment according to sharia principles. This study uses a descriptive qualitative approach with data collection techniques through interviews, observations, and documentation of Bank Muamalat Purwokerto. The results show that customer interest is influenced by several main factors, namely trust in sharia principles through the murabahah contract, a positive perception of gold as a stable investment asset, the ease of installment procedures that are flat and transparent, and the efficiency of the payment system through autodebit. In addition, social factors such as family recommendations and active promotions from the marketing department also strengthen customer interest. From the SWOT analysis, it was found that the main strength of this product lies in Bank Muamalat's reputation as a pioneering sharia bank and a stable installment system, while its main weaknesses are limited physical gold stocks and low public investment literacy. With increasing public awareness of sharia investment and the large market potential in Purwokerto, the Cicil Emas product has strong prospects for continued growth as a safe and Islamically-compliant long-term investment instrument.

This study aims to analyze the Effect of Return on Equity (ROE), Total Asset Turnover (TATO), Net Profit Margin (NPM) on Stock Prices in food and beverage companies listed on the Indonesia Stock Exchange for the 2020-2024 period. The approach in this study is to use a quantitative approach, and based on the objectives, this type of research is causal. The independent variables in this study include Return on Equity (ROE), Total Asset Turnover (TATO), and Net Profit Margin (NPM) and the dependent variable in this study is Stock Price. The population in this study is food and beverage companies listed on the Indonesia Stock Exchange, totaling 27 companies for the 2020-2024 period. This study uses the Purposive Sampling method, selecting 18 companies multiplied by 5 periods, resulting in a sample size of 90 samples in this study. This study uses descriptive statistical analysis using secondary data with descriptive statistical tests. Continued with the classical assumption test using the multiple regression model hypothesis testing method. This study uses panel data regression tool analysis with the help of SPSS 26 application tools. The results of the study show that: (a) Return on equity (ROE) has a positive effect on share prices, (b) Total Asset Turnover (TATO) does not have an effect on share prices, (c) Net Profit Margin (NPM) has a positive effect on share prices.

This study aims to analyze the influence of profitability as proxied by Return on Equity (ROE), solvency as proxied by Debt to Equity Ratio (DER), and liquidity as proxied by Current Ratio (CR) on firm value as proxied by Price to Book Value (PBV) in the Indonesian food and beverage sector. The study focuses on the 2019-2023 period, a timeframe uniquely defined by the economic disruption of the COVID-19 pandemic and its initial recovery phase. The research method employed is a quantitative approach using multiple linear regression analysis. The sample consists of 10 companies listed on the Indonesia Stock Exchange (IDX), selected through a purposive sampling technique, resulting in 50 firm-year observations. The results indicate that both partially and simultaneously, the variables of profitability, solvency, and liquidity have a significant positive influence on firm value. This finding suggests that during a period of systemic crisis, the capital market places a valuation premium on companies that can demonstrate holistic and comprehensive signals of financial health. The novelty of this research lies in its contextualization of the dynamic role of financial ratios as crucial signals amidst an unprecedented economic shock. This study provides an empirical explanation for why investors prioritized stability and resilience, thereby reconciling conflicting findings in prior literature regarding the impact of liquidity on firm value.

The purpose of this research is to analyze and find out how the company's growth, capital structure and company size affect stock prices in sub-sector, ceramics, porcelain and glass companies listed on the IDX for the 2018-2023 period. This research is an associative quantitative research using secondary data taken from the company's annual financial statements. The sampling technique in this study uses purposive sampling. In this study, 48 samples were obtained for 6 years (20182023). The analysis tool used in the regression analysis of panel data was conducted using E-views 13. Based on the research that has been carried out, it can be concluded that the company's growth partially has a significant effect on the stock price, the company's capital structure and size partially do not have a significant effect on the stock price. Then  the company's growth, capital structure and company size simultaneously have a significant effect on the stock price of companies in the ceramics, porcelain and glass sub-sector listed on the IDX for the 2018-2023 period.

This study aims to analyze the effect of cum and ex-dividend dates and company size on stock prices using the Dividend Payout Ratio (DPR) as a moderating variable. This study uses multiple linear regression analysis with moderating variables on companies listed on the Indonesia Stock Exchange. This research is based on signaling theory, which states that dividend information can serve as a signal for investors in making investment decisions. The results of the study indicate that all independent and moderating variables in the model simultaneously have a significant influence on stock prices. This suggests that the regression model used in this study is valid and can comprehensively explain stock price variations. This study implies that companies need to develop a more structured financial communication strategy, particularly in the disclosure of dividend information. Not only should the timing of dividend distribution be communicated, but the number of dividends to be distributed should also be clearly communicated to strengthen investor response. The implementation of this strategy must be accompanied by compliance with OJK and IDX regulations to maintain market confidence and increase the value of company shares.

This study aims to analyze the effect of Total Asset Turnover (TATO) on stock prices at PT Baramulti Suksessarana Tbk during the 2014–2023 period. TATO is an activity ratio that measures how efficiently a company utilizes its total assets to generate sales. This research employs a quantitative associative approach using secondary data obtained from the company’s annual financial statements published by the Indonesia Stock Exchange. Data were analyzed using simple linear regression to determine the relationship between the independent variable (TATO) and the dependent variable (stock price). The results show that TATO has a positive and significant effect on stock prices, with a correlation coefficient of 0.859 and a significance value of 0.001 (p < 0.05). This indicates that the more efficiently a company uses its assets to generate sales, the higher its stock price will be. The findings support the signaling theory and efficient market hypothesis, suggesting that asset efficiency serves as a positive signal for investors in evaluating firm performance.

This study aims to examine the effect of Return on Equity (ROE), Debt to Equity Ratio (DER), Current Ratio (CR), Total Asset Turnover (TATO), and Dividend Payout Ratio (DPR) on Price Book Value (PBV). The population of this research consists of food and beverage sub-sector companies listed on the Indonesia Stock Exchange during the 2020–2024 period. The sample was determined using a purposive sampling technique, resulting in 18 companies with a total of 90 data observations. This research employs a quantitative approach with secondary data. The analysis technique used is multiple linear regression. The findings indicate that Return on Equity (ROE) has a significant effect on Price Book Value (PBV), Debt to Equity Ratio (DER) also has a significant effect on Price Book Value (PBV), while Current Ratio (CR), Total Asset Turnover (TATO), and Dividend Payout Ratio (DPR) have no significant effect on Price Book Value (PBV).
