This research investigates the effect of constructive social capital such as religious tolerance, political participation, and marriage; and destructive social capital such as the corruption culture and discriminatory behavior towards the economic growth rate of member countries of the Islamic Cooperation Organization (OIC) 2014-2017. The results of the research estimation using the technique of fixed effect (FE) from the panel data of the OIC countries show that religious tolerance measured using the freedom of religion index (FRI) shows a positive and significant effect on the economic growth rate; political participation as measured by political rights index (PRI) has a significant negative effect on the economic growth rate; marriage measured using the percentage of married woman (PMW) has a positive effect on the economic growth rate but is not significant; corruption culture measured using the corruption perception index (CPI) has a negative and no significant effect on the economic growth rate; and discrimination behavior measured using discrimination and violence against minorities index (DVI) shows a negative and no significant effect on the economic growth rate.

The Covid-19 pandemic affected many sectors, one of which was the economic sector, so the government released three fiscal stimulus policy packages to deal with the impact of the Covid-19 pandemic on the economy. Starting on February 25, 2020, for the first volume, then for the second volume on March 21, 2020, and then the third volume of the fiscal stimulus package was released on March 31, 2020. The purpose of this paper is to identify the impact of the fiscal stimulus on economic output and labor income in Indonesia. The research method uses an input-output analysis model in identifying the impact of fiscal stimulus on economic output and labor income. The results of the analysis of the impact of the fiscal stimulus volume 1 show that the increase in fiscal stimulus in 2020 on the output of the Accommodation and Food and Drink Provision sector; Real Estate; and Other Services sectors cause changes in economic output. There are 3 sectors with the largest economic output affected by the increase in fiscal stimulus, namely the Agriculture, Forestry, and Fisheries sectors; Processing industry; and Wholesale and Retail Trade; Car and Motorcycle Repair. The impact of the fiscal stimulus volume 2 in the form of tax incentives, especially on PPh 21 in the Manufacturing Industry, has proven to have an impact on changes in total income in all sectors. The results of the analysis of the impact of fiscal stimulus volume 3 show that the increase in fiscal stimulus in 2020 on the output of the Agriculture, Forestry, and Fisheries sector; Processing industry; and Health Services and Social Activities cause changes in economic output. There are 3 sectors with the largest economic output affected by the increase in fiscal stimulus, namely the Agriculture, Forestry, and Fisheries sectors; Processing industry; and Health and Social Activities.

In contrast to the branches of mathematics in general that require only analytical skills through formula calculation, geometry requires other skills in the form of visual ability to understand. The student's analytical skills can be enhanced by theoretical learning methods. However, theoretical learning method will not be optimal in improving the visual ability. Another method is required that can encourage students' analytical and visual abilities. The learning method that suits these needs is a case study. The case study method in geometry lessons can be applied by creating scenarios that are divided into two stages: the preparation stage and the implementation stage. The preparation stage is related to the formulation of scenarios of case studies that will be conducted by the students in the field, while in the implementation stage the students conduct direct observation in the field based on the case study scenario at the preparation stage and then present the observation result through the presentation, accompanied by suggestion and evaluation from teachers.
