As a capital market investment, stocks have risks that must be managed. Therefore, investors should consider the returns and risks of investment products. This study aims to estimate the risk of insurance companies' loss when investing. The method used to estimate the level of risk is Value at Risk (VaR) based on Extreme Value Theory (EVT). The data used is secondary data in the form of daily stock closing prices from two insurance companies, AXA General Insurance and BRI Insurance, from January 2016 to January 2022. The data were used to estimate the risk value according to the EVT principle. As a result, Insurance AXA General Insurance, with 5.91% liquidity, has the lowest VaR value with a 99% confidence level, while BRI Insurance has 5.04%. We concluded from these results that AXA General Insurance has a lower investment risk. It means that each company has a different risk value. Therefore, investors should know these risk factors when choosing a company.

This study examines the effect of carbon emission disclosure and the Public Disclosure Program for Environmental Compliance (PROPER) on foreign ownership of manufacturing companies in Indonesia from 2018 to 2022 that publish annual reports or sustainability reports, registered with the Ministry of Environment and Forestry PROPER, and carbon emissions disclosure in the annual report and/or sustainability report. The analysis method uses the ordinary least squared (OLS) approach to study 28 PROPER manufacturing companies used as samples. The control variable used is return on equity (ROE), this is based on the idea that foreign investors are willing to invest in other countries to get a return on the equity or capital channeled to the company. The results show that carbon emissions disclosure has a significant positive effect on foreign ownership. Conversely, PROPER did not have any significant positive effect on foreign ownership. The results show interesting results that foreign investors are proven to consider environmental aspects in making decisions to invest in companies in Indonesia. On the other hand, the Indonesian government needs to ensure that its PROPER ratings can also provide benefits to foreign investors to attract their investment decisions.

Financial management faces 3 important decisions, namely funding, investment and dividends. The purpose of this study is to determine the effects of the fundamental factors such as leverage in financial management. Leverage is one of the factors of funding, investment and dividends that interdependently affect the value of the company. The method used in this study uses 2SLS (two-stage least square). There are 4 (four) equations in this study, namely the equation of leverage, investment, dividend and company value. Interdependence is shown based on leverage, investment and dividends. In the interdependence equation leverage, investment and dividends not only on one side act as endogenous variables but also act as exogenous variables on the equation of the company values. The results of the research on leverage equations show that investment affects leverage but dividends do not affect leverage. The investment equation shows the results of both leverage and dividend variables would not affect investment decision. Dividend equation also shows that leverage and investment variables also do not affect dividends. Moreover, the results of the company value equation show that the leverage variable would not affect the value of the company. But in-vestment and dividend variables affect the value of the company. The conclusion of this study is that there was a mutually influential relationship between the three variables of financial management before influencing company value.

The indicators of success in macro development can be measured from the economic growth, which is reflected in changes in the Gross Regional Domestic Product (GRDP). The factors which affect the economic growth are very complex. This study analyzes the economic growth and the factors that affect Sumatra island. The data used is panel data with descriptive analysis techniques and multiple linear regression. Based on the research results: Education, economic openness, road infrastructure, and investment have a positive and significant effect on economic growth and poverty and unemployment have a negative and significant effect on economic growth.

One subcategory of project scheduling is the resource constrained project scheduling problem (RCPSP). The present study proposes a differential evolution algorithm for solving the RCPSP making a small change in the method to comply with the model. The RCPSP is intended to program a group of activities of minimal duration while considering precedence and resource constraints. The present study introduces a differential evolution algorithm and local search was added to improve the performance of the algorithm. The problems were then solved to evaluate the performance of the algorithm and the results are compared with genetic algorithm. Computational results confirm that the differential evolution algorithm performs better than genetic algorithm.

The agricultural production, due to the specificity of the functioning of the agricultural industry, is influenced by factors that have significant impacts on agricultural enterprises and determine the importance of state support. The unpredictable factors of agrarian production such as weather, natural disaster, and epidemics increase the risks of agricultural business. That is why farmers need to attract investments. But some farmers do not attract investment because of government subsidies. Besides, using government subsidies could have a negative impact on agrarian business. So, it is necessary to establish the effectiveness of governance for agricultural production and food security in general.
