Environmental disclosure is the disclosure of information relating to the environment in the company's annual report. This disclosure aim is as a medium among companies, communities and investors that can be used as economic, social and political decision making. Industry type, company size, profitability, liquidity, environmental management systems, taxes, market share, and media coverage were considered to have influences on environmental disclosure. The study used quantitative analysis techniques with multivariate regression. The object of this research was the mining sector. The results showed that media coverage had a positive effect on environmental disclosure. This is because media coverage is a key communication function and is very important for management in CSR disclosure. In fact, communicating CSR through the media will enhance the company's reputation in the eyes of the public. The results of this study also indicated that environmental disclosure by companies in Indonesia was still relatively low. Therefore, companies need to increase their environmental disclosure in the annual report or sustainability report. Environmental disclosure is important for the company because it ensures transparency and accountability for the performance and long-term sustainability of the company.

Firm-specific risk causes opinion differences on whether it relates to price informativeness or errors. The main difference is related to the disparity in information transparency. Therefore, this study tests the relationship between accrual management and firm-specific risk based on information transparency. It was conducted on firms listed on the Indonesia Stock Exchange from 2015 to 2019. The results showed that accrual management positively affects specific risks, which is strengthened by information asymmetry. These results indicate that accrual management has the potential to occur in environments with low transparency or high information asymmetry. Accrual management inhibits actual information, causing errors in stock price assessments that indicate firm-specific risk. This proves that firm-specific risk shows a price error. These results are consistent with previous studies that discretionary accruals can measure earnings quality by considering the firm’s fundamental factors reflected in how non-discretionary accruals affect firm-specific risk. This study shows that risk fluctuates depending on firm-specific information.

Capital Asset Pricing Model (CAPM) is one of the estimated return models developed in conventional financial instruments that have different characteristics from Islamic financial instruments. So the CAPM model cannot be directly applied in Islamic financial instruments, so an estimation model is needed, namely the Shariah Compliant Capital Asset Pricing Model (SCAPM). This study aims to produce a SCAPM model that can be applied to estimate returns in Islamic financial instruments. The data used in the test is a list of sharia companies listed on the IDX, sharia company stock prices, Indonesia Sharia Stock Index (ISSI), yield of sukuk and return of Bank Indonesia Certificates (SBI) for the period 2010 - 2018. Testing is done by comparing expected return with the CAPM and SCAPM models. The SCAPM model used is to eliminate the risk free asset factor and replace it with inflation, zakat, and yield of sukuk. The results of the analysis using graphs and the compare mean test show that the results of the expected return with the SCAPM and CAPM models have no difference, so the SCAPM model can be used as an alternative model of return estimation in Islamic Financial Instruments on the IDX.

This research is a case study research at PT Garuda Indonesia Tbk (PT GIAA). The motivation for conducting the research was the existence of PT GIAA's fi-nancial reporting in 2018 which revealed a significant increase in profit which required PT GIAA to restate its financial statements in 2019. The analysis used was descriptive and quantitative analysis. The restatement of the financial state-ments has an impact on changes in reported earnings, namely there are losses, adjustments to accounts also cause some changes in the amounts recognized in the financial statements. On this basis, a quantitative analysis was carried out to determine the level of conservatism in the restatement of PT GIAA's financial statements. Based on accrual conservatism, the company still applies conserva-tism principles but in the restatement period of financial reporting in 2018 the level of conservatism decreased. Based on market conservatism, the market value of the company's shares is lower than its book value, this indicates that the company is aggressive in determining book value. Even the average stock return each year is negative and a sharp decline occurred during the restatement of fi-nancial statements. This indicates that market confidence decreases when the company restatement its financial statements.

Performance of Sharia and Conventional Stock during the Pandemic of Covid-19 in Indonesia 1. Introduction Pandemic Covid-19 which struck the world with 76 positively confirmed countries has a big impact on all sectors, including trading on the Indonesia Stock Exchange. On March 2, 2020 the Indonesian government issued a formal declaration that in Indonesia was confirmed Covid-19. The statement responded to the market with a decrease in the stock price of 236 shares or 35% of all traded stocks. The average stock price decrease was 0.08% in the trade close of 2 March 2020. The decline continued to occur and resulted in the Indonesian capital market experiencing trade pressures that resulted in a significant decrease in the combined Stock price index (JCI). So that the board of Directors of Indonesia Stock Exchange issued a decision of board of Director number: KEP-00024/IDX/03-2020 dated March 10, 2020 on the change of the guidelines for the continuity of trade in the Indonesia Stock Exchange in case of emergency, in order to maintain a regular, fair and efficient trading of securities Based on the decision of the Board of Directors, IDX held a temporary suspension of trade (trading halt) on 12, 13, 17, 19, 23 and 30 March 2020. The decline of the JCI on March 2, 2020 to 5,361.246 which was previously at the end of February JCI closed at 5,452.704. At the end of March 2020 it fell to 4,538.930 and by the end of April the JCI increased at level 4,716.403. This level lasts at the end of May that is at level 4,753.612 The Sharia stock index (ISSI), which is an index of Sharia stock groups, is also a decline. In early March, 155.310 was decreased compared to trade in the end of February at 156.750.At the end of March ISSI still declining at level 133.990. In late April and May 2020 ISSI was still in the range of 144.865 and 143.810. This shows that sharia stocks are the same as conventional stocks as affected by pandemic Covid-19. The difference with the previous crisis that had occurred in 2008, sharia stocks have better resilience in the economic condition of the crisis (Albaity & Ahmad, 2008). Based on the background, this research aims to determine if there is a difference between Sharia and conventional stock performance in the pandemic of Covid-19 using Sharpe ratio analysis. 2. Theoretical Background 2.1. Return (Gitman, 2009) defines return as follows: "Return is the total gain or loss over a certain period of time. Generally, a percentage of the initial investment value is measured as a change in value over the cash distribution over a period of time".(Berk & DeMarzo, 2017)"Return is the difference between the sale and purchase price of an asset plus a cash distribution expressed in a percentage of the purchase price". According to (Hartono, 2017)return there are two return realization and return expectations. Return of actual realization or return is calculated based on historical data while return expectation is expected return to be obtained by investor in future. 2.2. Risk The risk according to (Tendelilin...

This study aims to determine the effect of profitability, growth, leverage, and size on the earnings quality of Indonesian companies. It also shows that the preparation of financial reporting has referred to the International Financial Reporting Standards. However, capital market investments are being evaluated with an increasingly inadequate image of corporate earnings. The Indonesian Capital Market Supervisory Agency reported many cases of financial reporting indicating low earnings quality. Therefore, this study aims to analyze 556 non-financial companies that reported statements for 2017 -2019 and obtained 1280 data based on the unbalanced panel method. The results show that an increase in earnings quality is influenced by profitability, while a decrease is influenced by leverage, growth, and company size.
