Abstract

The Asteraceae family is a plant with attractive flower characteristics in terms of colour and size. Most of the flowers of this family are often infested by insects, especially the butterfly race. The tourist area of the Irenggolo waterfall was chosen as the research site because the area is still natural, with cold air temperatures allowing the abundance of the Asteraceae to thrive. This study was conducted to describe the type of inflorescence in each Asteraceae found. This type of research is descriptive qualitative with a survey method. Of the six species found, all of them are types of infinite and unbranched compound flowers; tube flowers have many similarities in the number of organs. The striking difference lies in the species Ageratum conyzoides L., which does not have ribbon flowers and has some pappus (petals) of 4. It is necessary to conduct further research regarding the causes of different types of ribbon flower layers in a population.

Abstract

This study aims to examine the long-term integration among Islamic capital markets in five ASEAN countries namely Indonesia (ISSI), Malaysia (FTSE-MB), Thailand (FTSE-SET), Singapore (FTSE-SGX), and the Philippines (MSCI-PH) along with the U.S. stock market (DJIA) before, during, and after the COVID outbreak. Utilizing a quantitative approach, the study analyzed daily closing prices from November 2018 (a year before the COVID-19 outbreak) to May 2024 (a year following the COVID-19 outbreak). We employed the Johansen cointegration test and the Vector Error Correction Model (VECM) to assess market cointegration. Results reveal that all ASEAN Islamic indices exhibit significant cointegration with the Dow Jones Industrial Average (DJIA). The FTSE-SET and MSCI-PH indices show a strong positive correlation with the DJIA; in contrast, the ISSI and FTSE-SGX indices display a negative correlation, suggesting potential diversification benefits for investors. The Granger Causality Test further identifies causal linkages between certain ASEAN indices and the DJIA. These findings underscore the influence of global dynamics on ASEAN Islamic markets, despite their unique characteristics. The results advocate for portfolio diversification and the formulation of adaptive economic policies to enhance the stability of ASEAN Islamic markets amid global financial volatility.

Abstract

This study aims to analyze the effect of international trade, which is focused on agricultural exports, as well as the effect of exchange rates on economic growth in the period 2019 - 2023. The method used is quantitative associative method with multiple linear regression approach, using secondary data obtained from the Central Bureau of Statistics (BPS), Bank Indonesia (BI) and other sources. The collected data were analyzed using SPSS software, and tested using the classical assumption test to ensure the accuracy of the model. The results showed that agricultural exports and exchange rates had no significant effect on economic growth. Overall, the variables studied do not explain all the factors that influence economic growth, so there are other factors that are not discussed in this study. It could be inferred that while the exchange rate has a negative impact on the dependent variable, agricultural exports have a favorable impact on economic growth.
