Abstract

In financial management theories an investor will act rationally and make a desicion to invest based on the rules in the financial management theory. Nevertheless, in reality the decision making to invest is very often irrational and not in accordance with the financial management theory. This deviation is caused by the bias of investors’ behaviour in making a decision. Investors who only focus on the return of an investment without paying attention to the risks are said to experience overconfidence bias. This research analyses the factors which are considered to influence investors with overconfidence bias in deciding the investment types. The factors are personality type, marital status, income level, work experience, and fields of study that have been taken. This research can contribute to completing the study of financial management, particularly in the investment decision and putting psychological factors in the analysis of financial management

Abstract

The purpose of this study is to confirm the effect of business performance and macroeconomics on stock returns in the industrial sector in the Indonesia Stock Exchange LQ45 index. This study examines eight variables from business performance and macroeconomics, namely: current ratio, debt-equity ratio, total asset turnover, return on equity, inflation rate, interest rate, exchange rate, and political stability to be tested for the effect on the stock return of the industrial sector. Using Generalized Least Square techniques, it is concluded that the Industrial sector in the Indonesia Stock Exchange is strongly influenced by macroeconomic factors rather than business performance factors. This is common in capital markets which are mostly dominated by foreigners because foreign investors are very sensitive to changes in a country's macroeconomic conditions especially if it is related to political conditions. From the iteration results, there are two multivariate regression models which are statistically considered the most suitable. The originality of this study is to prove statistically that political stability is very influential on LQ45 stock returns in the industrial sector on the Indonesia Stock Exchange

Abstract

As a developing country that still has to develop in all fields and to maintain its economic development, the Indonesian government requires significant funds for development. To fulfill the lack of funds obtained from the tax, the Indonesian government sells bonds. Indonesia's 10-year government bonds are known as Surat Utang Negara (or abbreviated as SUN). This study aims to confirm whether the inflation rate, exchange rate, political stability, and corruption control affect the yield of SUN. The research uses descriptive methods and explanatory studies with secondary data based on systematic sampling of periods chosen from January 2013 to December 2019. Multivariate regression equation models were used with a significance level of 5% for the t-test. The conclusions are: partially and simultaneously inflation rate, exchange rate, control corruption, and political stability have a significant effect on the Indonesian Government Bond. This research found that deteriorating political stability and control corruption would cause government bond yields to increase

Abstract

Dengan meningkatnya tantangan yang dihadapi oleh robot akibat kemajuan teknologi dan keragaman kasus, input yang diperlukan oleh robot menjadi lebih banyak dan variatif, sehingga tidak dapat diselesaikan hanya dengan if conditional yang sederhana. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan model machine learning yang dapat membantu robot navigasi untuk mengidentifikasi permukaan yang optimal dengan tingkat akurasi yang tinggi. Penelitian ini menggunakan random forest sebagai algoritma machine learning yang termasuk dalam kategori supervised learning untuk menghasilkan prediksi berdasarkan data latih. Data latih di augmentasi dengan data dari yang telah disintesis menggunakan CTGAN, yaitu sebuah metode yang menggunakan jaringan saraf tiruan untuk menghasilkan data tabular heterogen yang mirip dengan data asli. Metode ini juga dapat melindungi privasi data asli dengan menggunakan privasi diferensial dan pembelajaran federasi. Setelah model machine learning dibangun, model diuji dengan data uji yang dibuat. Model machine learning yang berbasis random forest ini menunjukkan kinerja yang baik dengan mencapai akurasi 90% pada prediksi data uji.

Abstract

Analyzing the influence of macroeconomic factors on the Jakarta Composite Index (JCI) is the objective of this study. Changes in the index value indicate changes in market conditions. The movement of the JCI is influenced by internal and external factors. External factors include macroeconomic factors that come from outside the company. The independent macroeconomic variables used in this study are exchange rate (EXR), general election (GE), inflation (INF), interest rate (INT), New York Stock Exchange (NYSE), world gold price (WGP), world oil price (WOP), and JCI prior time (JCI(-1)). Sampling in this study used purposive sampling, resulting in a sample of monthly time series data covering two election events from January 2016 to February 2024. The multiple linear regression analysis test results show that the Jakarta Composite Index (JCI) is not affected by GE, INF, or WGP. In contrast, EXR, INT, NYSE, WOP, and JCI(-1) have a significant effect on JCI. Based on the results of the factor influence study, 94.2% of the JCI may be influenced by the variables studied. Meanwhile, factors that are not included in this research model have an influence of 5.8%. The suggested implication is that the government needs to continue to encourage economic growth to increase the attractiveness of investment in Indonesia.

Abstract

The Indonesian minimarket sector is undergoing rapid transformation, driven by intensified competition, decentralization, and digital disruption. This study investigates the competitive advantage of Alfamart, a leading minimarket chain in Indonesia, by employing an integrative SWOT and PESTEL framework. Using a qualitative case study approach—including interviews, surveys, and observational data—the research identifies key internal strengths such as store network scale, brand loyalty, and digital initiatives like Alfagift, alongside weaknesses including operational cost rigidity and limited pricing flexibility. The analysis reveals external opportunities in scalable franchising and rising consumer demand for health-oriented retail, while highlighting threats from regulatory restrictions and digital-native competitors. The findings position Alfamart in an aggressive strategy quadrant, emphasizing the importance of aligning internal capabilities with macro-environmental dynamics. The study concludes that strategic agility is essential for sustaining competitiveness in a decentralized and digitally disrupted market. Limitations include qualitative scope and a localized sample, with future research recommended to explore broader demographics and predictive modeling.
