This study aims to comprehensively describe the psychological dynamics of Natta's character in the novel Rumah Tanpa Cahaya through the framework of Sigmund Freud's psychoanalytic theory. The main focus of the study is to analyze the structural interactions of personality including the Id, Ego, and Superego, and to identify various self defense mechanisms activated by the character due to the internal conflict he experiences. The method used is descriptive qualitative with a literary psychology approach as the main analytical basis for dissecting the hidden inner character. The results of the study indicate that Natta's character's behavior is a form of integrative struggle that demands immediate gratification (Id), rational consideration of painful reality (Ego), and strong moral pressure from the internalization of social norms (Superego). Natta's Id demands the fulfillment of basic needs for security and affection. Meanwhile, the Superego provides moral pressure that triggers disproportionate anxiety. Natta's Ego operates as a mediator that works hard to balance the drives of the Id and the demands of the Superego, which forces the Ego to activate self-defense mechanisms such as repression, rationalization, and especially sublimation. This mechanism serves as a psychic barrier to maintain her mental stability and prevent her from experiencing total collapse due to the accumulation of past trauma. Overall, this novel depicts the complexity of the human psyche in the face of existential crises and unresolved past wounds.

These scores are significantly above the safe threshold of 2.675, indicating that the company is in a healthy financial state with a very low risk of bankruptcy. Overall, PT Sido Muncul Tbk demonstrates stable financial performance, supported by a strong capital structure and consistent operational results. The Altman Z-Score model also proves to be an effective early-warning tool for identifying potential financial problems.

This study examines the optimization of military defense in North Sulawesi as a supporting pillar for Indonesia’s new import gateway. Positioned strategically on the Pacific rim, North Sulawesi is expected to become a hub for imported goods to support national economic equalization. However, this import route shift also brings security challenges, including military and non-military threats such as smuggling, maritime crimes, and potential infiltration by terrorist groups. This research employs a qualitative descriptive method based on literature study, focusing on the analysis of naval and air defense strategies, modernization of main weapon systems (alutsista), and the enhancement of human resources within the Indonesian National Armed Forces (TNI). The results indicate that strengthening defense infrastructure, including the addition of warships, patrol vessels, and modern fighter aircraft, is urgently needed to maintain regional stability. Furthermore, the application of the smart defense concept, integrating advanced technology with local community empowerment, can sustainably enhance maritime resilience. Investment in the defense sector has been shown to create a conducive climate for international trade, boost investor confidence, and strengthen Indonesia’s economic connectivity with the Asia-Pacific region. This study recommends synergy between the Ministry of Defense, TNI, and the national defense industry to accelerate the modernization and maintenance of alutsista, while ensuring the security of trade routes in North Sulawesi. With these measures, North Sulawesi can function optimally as a strategic import gateway that supports national economic growth and reinforces state defense.

Traffic performance on urban road segments is strongly affected by vehicle volume and travel time, particularly during peak periods. This study analyzes the relationship between travel duration and the total number of vehicles passing along Otto Iskandar Road as an illustration of urban traffic conditions. Data were collected through field surveys, focusing on two main variables: average vehicle travel time and total traffic volume. Statistical analysis was performed using IBM SPSS Statistics, including normality testing and the Wilcoxon Signed Rank Test to identify potential differences between the observed variables. The results show a difference in average values between travel duration and vehicle volume; however, this difference is not statistically significant at the 95% confidence level (p = 0.180). These findings indicate that increases in traffic volume do not always lead to proportional increases in travel time, although they can still influence the stability and efficiency of traffic flow. The results are consistent with previous studies, such as Halim (2021), who reported that U-turn movements affect speed and traffic performance, and Handayani et al. (2024), who found that parking activities and vehicle maneuvers reduce road capacity. Other studies also highlight the impact of side friction and traffic flow variations on speed and saturation levels. Overall, this study emphasizes the importance of managing vehicle flow and monitoring travel time in urban transportation planning and traffic management.

This study aims to analyze the effectiveness of the zakat program in empowering Micro, Small, and Medium Enterprises (MSMEs) in Pasir Penyu District, Indragiri Hulu Regency. This study uses a descriptive qualitative approach with data collection techniques through interviews, observation, and documentation. Research informants consist of MSMEs who receive productive zakat and zakat managers. The results of the study indicate that the productive zakat program has a positive impact on MSME empowerment, especially in increasing business capital, business sustainability, and income stability of mustahik. In addition, the zakat program also encourages increased skills and motivation of MSMEs in managing their businesses. However, the effectiveness of the program still faces various obstacles, such as limited zakat funds, suboptimal business mentoring, and limited managerial capabilities and market access of MSMEs. The conclusion of this study shows that the productive zakat program in Pasir Penyu District, Indragiri Hulu Regency is quite effective in empowering MSMEs, but requires strengthening in terms of mentoring, program management, and business capacity development so that its impact is more optimal and sustainable.

This study examines the implementation of the Coretax system in preparing electronic withholding tax slips (e-Bupot) and submitting Monthly Income Tax Article 21 (PPh 21) Returns at PT RSA. Coretax, launched by the Directorate General of Taxes (DGT) and officially implemented on January 1, 2025, is part of the government’s effort to modernize tax administration and improve taxpayer compliance. The research uses a qualitative descriptive method with a case study approach. Data were obtained through interviews with personnel responsible for PPh 21 administration, direct observation of e-Bupot preparation and monthly tax return filing through Coretax, and documentation review of tax reports and withholding slips. The analysis compares PT RSA’s practices with applicable tax regulations and identifies technical challenges during system use. The results show that PT RSA has complied with prevailing regulations, including the application of the Average Effective Rate (TER) and the utilization of Coretax for tax administration. However, technical constraints remain, particularly unstable internet connections and slow Coretax server performance during peak reporting periods, leading to data entry delays and upload failures. Therefore, improvements in system stability and performance are needed to support timely reporting and optimal tax compliance.

This study analyzes the economic phenomenon known as the "Purbaya Effect" in the Indonesian capital market during the second half of 2025. This phenomenon is characterized by a significant surge in the Jakarta Composite Index (IHSG), which broke the All-Time High (ATH) record 21 times within four months following the appointment of Purbaya Yudhi Sadewa as Minister of Finance. Using a mixed-methods approach combining quantitative market data analysis and qualitative policy review, this research finds that the "Purbaya Effect" is driven by aggressive liquidity injection policies (Rp 200 trillion), institutional trust built during his tenure at LPS, and strong narrative economics. However, this study also identifies significant risks related to exchange rate volatility and potential economic overheating. The findings suggest that while the "Purbaya Effect" successfully restored short-term investor confidence, long-term sustainability depends on the balance between growth acceleration and macroeconomic stability.

The rapid advancement of information technology has encouraged business actors to adopt digital transformation; this situation is also experienced by Pabrik Tahu Macanan, a small scale tofu factory in Magelang that still relies on manual systems in operation. This  study aims to analyze the implementation of management information systems in supporting digital transformation and risk management at Pabrik Tahu Macanan; a descriptive qualitative approach was applied, using interviews, observations, and documentation as date collection methods. The findings reveal that digital information systems have the potential to improve efficiency, recording accuracy, and internal control; however, their implementation remains limited due to human resource constraints and low adaptability to new technologies. The research also found that simple risk management practices such as regular machine maintenance and manual bookkeeping remain effective in maintaining business stability. The implication of this study indicates that a gradual implementation of digital based information systems, supported by training and supervision, can serve as a strategic step to enhance competitiveness, operational efficiency, and sustainability for traditional SMEs like Pabrik Tahu Macanan.

This study aims to provide a comprehensive overview of the implementation of green finance and its relationship with the financial performance and profitability of banking institutions in Indonesia. Although sustainable finance policies have been continuously strengthened by regulators and stakeholders, the contribution of green financing to overall banking performance is still developing gradually, making it important to conduct a more focused and systematic analysis of its effectiveness. This research specifically aims to describe the application of green financing practices, assess financial performance conditions, and analyze bank profitability during the 2020–2024 period. The study employs a descriptive quantitative approach using secondary data on green financing distribution, financial performance indicators such as the Capital Adequacy Ratio (CAR), Non-Performing Loans (NPL), and Loan to Deposit Ratio (LDR), as well as profitability measured through Return on Assets (ROA). The findings indicate that the implementation of green finance has the potential to enhance long-term financial stability and improve profitability in the banking sector. This study implies that expanding green financing can serve as a relevant and sustainable business strategy for the banking industry while simultaneously supporting national sustainability and environmental development objectives.

This study aims to analyze the role and effectiveness of Islamic monetary policy in Indonesia in facing digital transformation, particularly through the instruments of Sertifikat Bank Indonesia Syariah (SBIS) and Sukuk Bank Indonesia (SukBI). The digital transformation of the national financial system demands an adaptive monetary policy that remains grounded in the principles of maqashid shariah. In the context of Islamic economics, monetary policy not only functions to regulate the money supply and maintain price stability but also ensures the realization of justice and economic welfare. This research employs a descriptive qualitative approach, using literature-based data collection from official publications of Bank Indonesia, the Financial Services Authority (OJK), and relevant academic references on Islamic monetary policy. The analysis adopts an inductive approach by examining the roles of SBIS and Sukuk BI in supporting the stability of the Islamic financial system and their alignment with maqashid shariah values such as al-‘adl (justice), al-wudhuh (transparency), and ar-rawaj (circulation of wealth). The findings indicate that digitalization has positively impacted the efficiency and transparency of Islamic monetary instruments, where SBIS plays a role in regulating the liquidity of Islamic banks in a non-usurious manner, while Sukuk BI serves as an essential instrument in maintaining national economic stability. Nevertheless, challenges remain, including the limited digital infrastructure for Islamic finance and the need to strengthen regulations to ensure that digital monetary systems remain consistent with sharia principles.

This study presents a comprehensive evaluation of three main Islamic monetary instruments Sukuk, the Islamic Interbank Money Market (PUAS), and Sharia Repo to strengthen the resilience and stability of Indonesia’s Islamic financial system. Using a descriptive literature review method, this study analyzes relevant academic sources, regulatory frameworks, and policy reports. Sukuk is examined as an asset-based instrument that plays a crucial role in medium- to long-term financing and fiscal management. PUAS is analyzed as a mechanism for short-term liquidity management among Islamic banks based on mudharabah and wakalah contracts. Meanwhile, Sharia Repo is evaluated through the sale and repurchase mechanism of Sharia State Securities (SBSN) to support liquidity stability in Islamic banking. The findings reveal strong synergy among these instruments in managing excess liquidity, controlling inflation, and strengthening the transmission of Bank Indonesia’s monetary policy in compliance with Sharia principles. This study recommends enhancing public literacy, strengthening innovative regulatory frameworks, and developing Islamic financial infrastructure to promote inclusive and sustainable growth in Indonesia’s Islamic financial sector.

Government expenditure is a great reason in economic stability and its impact on the balance of payments is dire. In this light, this paper seeks to use the time series analysis method and the ARDL model to investigate the association between the balance of payments of Iraq and the public spending within the 2004-2023 period. The Eviews 13 software was used to analyse it. The findings show that there is a positive association between spending by the people and balance of payment especially at the short run. The latter findings indicate that the efficiency of government expenditure reform is a necessary tool to accomplish the expansion and close the balance of payments deficit. This study highlights the importance of strategic fiscal policies and government spending in achieving a balanced economy and sustainable growth. Additionally, it emphasizes the need for continuous monitoring and adjustment of public spending to ensure its alignment with national economic objectives. The findings contribute to the understanding of fiscal policy implications in developing economies, especially in the context of Iraq’s economic challenges.  

Criminal offenses of theft are one of the most frequent forms of crime in society and have wide-ranging impacts, not only on the individual victim but also on legal order and social stability. This study aims to analyze the impact of theft offenses on legal order and social life, while also examining the role of criminal law in addressing such crimes. The research method used is qualitative with a descriptive approach through literature study, observation, and interviews with law enforcement officers and the public. The results of the study show that the prevalence of theft offenses can decrease public safety, weaken public trust in law enforcement agencies, and disturb social order and harmony. Furthermore, theft also leads to a decline in legal compliance and an increase in the potential for vigilante justice. Therefore, consistent, effective, and just law enforcement is required, along with increasing public legal awareness as efforts to maintain legal order and create a safe and orderly social life.

This study aims to determine the role of Islamic scholars in developing Islamic education, then analyze the contribution of the Islamic organization Nahdlatul Ulama (NU). This research method is a library study (library research) with historical documents (historical document research) with a qualitative approach. Data obtained from two search sources, “Google Scholar” and “ScienceDirect.” The discussion in this article identifies, first, the role of Islamic scholars in developing Islamic education, namely: managing Islamic boarding schools as centers of Islamic education; maintaining Islamic identity and nationalism; establishing and managing madrasas; teaching Islam informally; and helping maintain social stability. Second, the contribution of the Islamic organization Nahdlatul Ulama (NU) includes maintaining Islamic boarding schools as centers of Islamic education, developing a curriculum based on Islamic tradition, instilling a spirit of nationalism through education, establishing madrasas and non-formal educational institutions, and maintaining traditional Islamic educational networks. In addition to preserving religious heritage, these ulama and the NU organization taught the next generation about knowledge and a sense of nationalism, strengthening the foundation of Indonesian society during the colonial period.

This study aims to analyze the influence of macroeconomic variables in the form of the dollar exchange rate, inflation, and Gross Domestic Product (GDP) on the Composite Stock Price Index (JCI) in Indonesia for the period 2010–2024. The research method used is a quantitative approach with multiple linear regression analysis using time series data obtained from Bank Indonesia, the Central Statistics Agency (BPS), and the Indonesia Stock Exchange (IDX). The data analysis technique was carried out through classical assumption tests and hypothesis testing to determine the relationship between variables. The results of the study show that partially GDP has a significant effect on the JCI, while inflation and the dollar exchange rate tend not to have a significant effect. However, simultaneously these three variables have a significant influence on the JCI. These findings show that macroeconomic stability is very important in maintaining the performance of the capital market in Indonesia and can be a reference for investors in making investment decisions. In addition, the results of the study confirm that national economic growth is the main indicator that market participants pay attention to in assessing investment prospects. Therefore, the government needs to maintain economic stability through effective and sustainable fiscal and monetary policies.

This research offers an in-depth examination of three primary Sharia monetary tools—Sukuk, the Sharia Interbank Money Market (PUAS), and Sharia Repo—aimed at enhancing the resilience of Islamic financial systems in Indonesia. Through a descriptive review of existing literature, the paper details Sukuk as asset-supported securities for medium- to long-term funding, PUAS operations grounded in mudharabah and wakalah agreements for brief interbank dealings, and Sharia Repo via SBSN sell-and-buyback arrangements to streamline Sharia bank liquidity. Results indicate these tools work in tandem to handle surplus funds, curb inflation, and bolster Bank Indonesia's monetary framework absent any speculative practices. Policy recommendations emphasize advancing education efforts, regulatory innovations, and infrastructural upgrades to promote equitable expansion within Sharia finance.

The COVID-19 pandemic has increased public interest in investing, especially in the banking sector, which is known for its stability. However, many investors still lack an understanding of fundamental analysis. This study aims to examine the effect of Return on Asset (ROA), Return on Equity (ROE), and Net Profit Margin (NPM) on stock prices of banking companies listed on the Indonesia Stock Exchange during the 2011–2023 period. The research used a quantitative approach with purposive sampling and multiple linear regression analysis using SPSS. The results show that ROA has no significant effect on stock prices. In contrast, ROE has a significant negative effect, while NPM has a significant positive effect on stock prices. These findings indicate that investors tend to consider net profit margins more than asset efficiency, and that high ROE may be perceived as a signal of high leverage risk. This research is expected to provide insights for investors in assessing banking performance before making investment decisions.

This study examines the factors that cause fraud in financial reporting. The study analyzed 195 data points from 39 financial institutions listed on the Indonesia Stock Exchange (IDX) during the period 2019 to 2023 using a purposive sampling technique. The research applied multiple linear regression analysis to analyze the impact of governance independence and performance variables on the likelihood of fraudulent financial reporting. The independent variables include financial targets assessed by profitability (return on assets [ROA]), financial stability measured by changes in assets, external pressure measured by the debt-to-equity ratio (DER), and the proportion of independent commissioners as a measure of good corporate governance. The study proves that financial targets affect fraudulent financial reporting, while financial stability, external pressure, and independent commissioners do not influence fraudulent financial reporting. The findings of this study provide valuable insights for regulators, investors, and management to enhance oversight and reduce the risk of fraud in the banking sector.
