The implementation of ballast water management is a very important strategic step in preventing marine environmental pollution, because ship ballast water often becomes a route for the spread of invasive alien species that have the potential to disrupt the balance of the ecosistem, harm the maritime economic sector, and endanger human health. This study focuses on ballast water management practices on the MT Timur Laut Mas 2 ship, with the aim of assessing how the procedures are implemented in order to prevent the entry of alien species, reviewing the implementation of both international and national regulations, and evaluating the performance of the Ballast Water Management Sistem (BWMS) technology applied. This study uses a descriptive qualitative method based on a case study, with data collection through interviews with ship crews and company management, direct observation on board the ship, technical documentation, and a review of supporting literature. The results of the study show that the implementation of the IMO Ballast Water Management Convention (BWMC) regulations on ships has been realized through the preparation of a Ballast Water Management Plan, detailed recording in the Ballast Water Record Book, and the use of a BWMS that relies on filtration technology and ultraviolet radiation. However, the implementation still encounters obstacles in the form of limited crew understanding of system operation, variations in water quality along the shipping route that affect filtration effectiveness, and technical obstacles in equipment maintenance. Therefore, a combination of compliance with international regulations, improving crew competency through continuous training, and optimizing sistem operations are key factors in strengthening the effectiveness of ballast water management. These findings confirm that the application of modern technology in accordance with regulatory requirements can enhance marine ecosistem protection while ensuring the sustainability of the maritime industry, thus positively contributing to environmental sustainability and the stability.

Diastasis Recti Abdominis (DRA) is a common postpartum condition in women, characterized by separation of the rectus abdominis muscles due to a weekend linea alba. This case study aimed to evaluate the effectiveness of e combined core activation.and curl-up exercise program in reducing intra-recti distance in a postpartum patient.The subject was a spontaneous postpartum woman at 39 weeks of gestation. Initial assessment revealed intra-recti distance of 28 mm above and 17 mm below the umbilicus, exceeding normal limits. The intervention consisted of a 4-day program including curl-up and five core activation excercises : diaphragmatic breathing, abdominal drawing-in manuver, supine pelvic tilt, heel slide and knee fall out. Measurements showed no significant reducyion in intra-recti distance; however, the patient reported improved abdominal tightness and core stability. The study concludes that although measurable changes were not significant within a short evaluation period, the intervention had positive subjective effects. Longer-term assessment is recommended for more conclusive results.    

The increasing number of devices connected to the network and the rapid growth of data traffic have posed challenges in managing conventional networks. Traditional networks often experience inefficiencies in handling high traffic loads due to static traffic management, leading to congestion in some network paths while others remain underutilized. Software-Defined Networking (SDN) has emerged as an innovative solution by separating the control plane and data plane, enabling more flexible, centralized, and programmable network management. This study evaluates the performance of OpenFlow-based SDN using the ONOS Controller and compares it with conventional home Wi-Fi networks based on the TIPHON standard. The simulation was conducted using Virtual Machines (VMWare) and Mininet, which were connected to the ONOS Controller via the OpenFlow protocol, while the conventional network testing was performed using the Command Prompt. The testing included three data transmission scenarios: 1 host to 1 host, 2 hosts to 1 host, and 2 hosts to 2 hosts simultaneously, with measured parameters including delay and packet loss. The results indicate that in the 1 host to 1 host scenario, both SDN and conventional networks had a delay of less than 150 ms and 0% packet loss. However, in the 2 hosts to 2 hosts scenario, the conventional network experienced an increase in delay and packet loss of up to 17%, whereas SDN remained stable with a delay below 150 ms and 0% packet loss. This confirms SDN's superior efficiency in handling high network traffic through more dynamic traffic distribution. Additionally, this study confirms that SDN's centralized control allows for more adaptive traffic management, reduces congestion, and improves overall network stability. These research demonstrate SDN's efficiency in handling high traffic loads, making it a superior solution for modern network demands.

The selection of the head of government is a fundamental aspect of the constitutional system that reflects the political and legal character of a state. Although Indonesia and Malaysia share similar historical roots, they adopt significantly different systems of governance. This study addresses two core issues which are about the structure and mechanism of executive and legislative power, and the impact of the presidential threshold and parliamentary coalition on governmental stability. Using a normative juridical method with statutory and comparative approaches, the findings reveal that Indonesia, under a presidential system, applies a nomination threshold to ensure political stability, yet it may restrict political access. Meanwhile, Malaysia’s parliamentary system is more flexible but vulnerable to instability due to coalition dynamics. This study recommends a reassessment of Indonesia’s presidential threshold for a more democratic process and strengthening of political stability mechanisms in Malaysia.

Early marriage is a complex social issue that requires special attention due to its negative impacts on individual development, health, and family stability. In Indonesia, policies related to early marriage are regulated in Law No. 16 of 2019, which sets the minimum age for marriage. The Office of Religious Affairs (KUA) Medan City plays a crucial role in addressing and preventing early marriage through various policies and programs, one of which is youth counseling and the certificate of marriage eligibility program. This study aims to analyze KUA Medan City's policies on handling and preventing early marriage and to assess the effectiveness of these programs. The research was conducted using a qualitative approach through an internship at KUA Medan City, involving observation and interviews with relevant stakeholders. The findings show that KUA Medan City has implemented policies to address early marriage effectively, although there are several challenges in its implementation, such as a lack of public understanding regarding the legal marriage age and low interest in participating in marriage counseling programs. In conclusion, while significant efforts have been made, there is still a need to raise public awareness and expand access to services provided by KUA to reduce the incidence of early marriage in the area.

This study aims to examine the Islamic perspective on the process of electing leaders, focusing on the hadith narrated by Al-Bukhari that warns of the dangers of entrusting authority to those who are not qualified. Using a descriptive-analytical method with a normative juridical approach, this research analyzes primary sources such as the hadiths in Sahih Al-Bukhari and relevant statutory regulations, supported by secondary sources from related scholarly literature. The findings reveal that leadership in Islam is a great trust (amanah) that demands strict fulfillment of Shari'ah criteria, including justice, trustworthiness, knowledge, and honesty. Entrusting leadership to incompetent individuals may lead to widespread social and political collapse, as indicated by the Prophet Muhammad (peace be upon him) in his hadith. Furthermore, the community’s negligence in electing suitable leaders is considered a collective sin that significantly affects societal stability. Therefore, Muslims must exercise greater vigilance, critical thinking, and responsibility in choosing their leaders to maintain social order in line with the principles of shura and Islamic values.

This study uses the Mean Value Analysis (MVA) approach to analyze the queuing system at the Mixue Ice Cream & Tea cashier counter on Jalan Pahlawan in Magelang City. The MVA method was chosen because it can handle general time distributions between arrivals and services. The research was conducted through direct observation and interviews over the course of two days, during which time data was collected on the time between arrivals and customer service. The analysis revealed that the system was not in a steady state, as the arrival rate (0.0122 customers per second) exceeded the service rate (0.0111 customers per second). High service variability (CV = 276.30%) compared to arrival variability (CV = 69.46%) indicates service instability. On average, customers waited 47.08 seconds, and the total time in the system was 137.17 seconds. These results are important because they indicate the need for increased efficiency and standardized services to prevent a decrease in service quality.

Background: Chinese betel (Peperomia pellucida L.) is an herbal plant rich in bioactive compounds such as flavonoids, alkaloids, and tannins that have the potential to be antioxidants, antimicrobials, and antidiabetics. However, the stability and absorption of its active compounds in the body is still a challenge. Microencapsulation technology and  a floating drug delivery sistem (FDDS) can improve the effectiveness and stability of herbal preparations. Objective: This study aims to formulate and evaluate floating microencapsulation preparations containing Chinese betel herb ethanol extract using modern drug delivery technology. Methods: Ethanol extracts were obtained by maceration method and formulated by ionic gelation technique using a combination of sodium alginate and chitosan at three concentration variations (0.25%, 0.5%, and 0.75%). The evaluation included morphological analysis with SEM, ex vivo buoyancy test on the stomach of Wistar rats, determination of moisture content, and physical stability test using the cycling test method. Results: Microencapsulation with a concentration of 0.75% showed the most compact and delicate morphology, the lowest moisture content (0.64%), and the best physical stability. All formulations are capable of floating, with the longest buoyancy time at a concentration of 0.25% for 8 hours. There were no significant physical changes after six cycles of extreme temperatures. Conclusion: Microencapsulation preparations of Chinese betel ethanol extract in a natural polymer-based floating system show good stability and potential as an innovative herbal formulation to extend retention time in the stomach.    

This study discusses Indonesia's security diplomacy strategy within the ASEAN framework and its contribution to international security stability. A literature study approach is used to examine the dynamics of Indonesia's diplomacy in regional forums such as the ASEAN Defense Ministers' Meeting (ADMM), ADMM-Plus, and the ASEAN Regional Forum (ARF). Indonesia, as a country with a strategic geographical and political position, plays an important role in promoting collective security based on cooperation and dialogue. However, the implementation of this diplomacy is faced with various challenges, including great power rivalry in the Indo-Pacific, capability gaps between ASEAN member countries, and the complexity of non-traditional threats such as cybersecurity and transnational terrorism. This study shows that although ASEAN has a regional security mechanism, its effectiveness still depends on the consistent leadership of key countries such as Indonesia in promoting an adaptive, inclusive, and consensus-based approach. The results of the analysis indicate that Indonesia's security diplomacy has the potential to strengthen ASEAN's legitimacy at the international level, as long as it is able to overcome internal limitations and synergize with global interests.

The purpose of this study is to examine how the growth of digital payment systems has affected Indonesia's financial system and rupiah stability. More people are using digital payment methods like e-money, credit cards, debit cards, RTGS, and QRIS as a result of technical advancements. Additionally, Bank Indonesia still encourages the adoption of digital payment methods to speed up, secure, and streamline transactions. The Two Stage Least Squares (TSLS) method is used in this study's simultaneous regression model, which employs secondary data from 2020 to 2024. The findings indicate that while inflation has a positive but negligible impact on the exchange rate, the use of credit cards and RTGS has a considerable positive impact. In the meantime, debit cards and e-money significantly reduce inflation. Inflation is significantly reduced by QRIS and the exchange rate. In order to maintain Indonesia's economic stability, it is crucial to keep enhancing literacy and security when using digital payment methods.

Good Corporate Governance (GCG) is the main pillar in maintaining investor trust and capital market stability. In the midst of dynamic capital market developments, the principle of transparency and accountability is a key element in building public trust and ensuring investor protection. Law No. 40 of 2007 concerning Limited Liability Companies (UUPT) as the main legal framework for regulating corporate entities in Indonesia, has a strategic position in regulating the implementation of Good Corporate Governance (GGC) principles, especially in the capital market supported by public companies. This study aims to examine the legal implementation of transparency and accountability obligations in Good Corporate Governance (GCG) as regulated in the UUPT and linked to the obligations of public companies in the capital market. This study applies a normative legal approach with a descriptive analysis method to statutory regulations, legal literature, and literature studies from five journals and five relevant law books. The results of this study indicate that the UUPT has emphasized the responsibility of corporate organs in implementing the principles of openness and accountability. Therefore, stricter supervision and strict enforcement of sanctions are needed so that the principles of Good Corporate Governance are truly implemented in real terms.

This study aims to identify the description of Commitment and Marital life Satisfaction. This study uses the systematic literature review (SLR) method, in order to answer research questions in a structured manner, by referring to the PRISMA 2020 model by reviewing 100 articles with keywords, namely (1) marriage commitment, (2) marriage satisfaction, and (3) commitment and marital life satisfaction. This research used the EndNote X9 application to obtain 5 articles from the Google Scholar database with the help of Harzing Publish or Perish (PoP). The results of this study show that commitment and marital life satisfaction are interrelated in maintaining marital harmony. Commitment, demonstrated through responsibility, support, and long-term orientation, is the foundation of marital stability. Couples with high commitment are better able to deal with challenges such as age difference or long distance thanks to open communication and effective conflict resolution. Factors such as religion, social support and the presence of children also affect satisfaction. Religious values strengthen relationship resilience, while unfulfilled expectations for children can decrease satisfaction.

The management of national border areas is a strategic issue in the modern international system, directly linked to sovereignty, national security, and regional stability. This study aims to examine the role of international law in border management through a qualitative literature-based approach. Findings indicate that core principles of international law, such as uti possidetis juris, state sovereignty, and non-intervention, serve as the normative foundation for boundary formation, recognition, and dispute resolution. Current challenges such as illegal immigration, infiltration, and territorial claims demand the strengthened implementation of international law within national policy. Local government involvement and economic diplomacy also play vital roles in building adaptive and responsive border governance. In Indonesia’s case, land and maritime border dynamics highlight the need for a comprehensive strategy that integrates legal, diplomatic, and regional development aspects. This study underscores the importance of synergy among state actors to safeguard territorial integrity and foster sustainable cross-border cooperation.

The Indo-Pacific region, being vast and full of potential, has become an arena for complex geopolitical competition among major powers. This article analyzes the Super Garuda Shield Exercise as an important instrument in responding to those dynamics. Using the approach of the balance of power theory and defense diplomacy, this article discusses the Super Garuda Shield exercise as an instrument of the balance of power in great power competition and its role as a tool of Indonesia's defense diplomacy. The research results show that the Super Garuda Shield exercise is an important instrument in the balance of power strategy in the region. Through this defense cooperation, Indonesia seeks to balance China's growing influence without getting trapped in a formal alliance. This demonstrates how Indonesia implements an independent-active foreign policy and its proactive role as a middle power in maintaining regional stability. This article emphasizes the importance of collaboration and coordination to establish a regional security order that is adaptive to increasingly complex geopolitical dynamics.

This study examines the contribution of the thoughts of three important figures in modern Islamic economics, namely Muhammad Baqir al-Sadr, Ibrahim Umar Vadillo, and M. Umer Chapra. Using a qualitative approach through literature study, this research critically analyzes their works and ideas. The results of the study show that the three of them built three main pillars of the contemporary Islamic economic paradigm. The first pillar is normative-ethical which is asserted by al-Sadr, emphasizing the value of justice and ethics. The second pillar is the structural-monetary of Vadillo, who proposes a gold dinar and silver dirham-based monetary system for economic stability. The third pillar is Chapra's maqashid-policy, which emphasizes the application of sharia's maqashid principles to realize social welfare and economic justice. These three pillars complement each other in forming the foundation of an integral, applicable and relevant Islamic economy to face global challenges. This research makes an important contribution in formulating an adaptive and sharia-based Islamic economic framework.

The practice of divorce without going through a formal court process, commonly referred to as informal or unregistered divorce, remains prevalent in Indonesian society despite clear regulations outlined in Law Number 1 of 1974 on Marriage. This paper aims to examine the legal dimensions of such practices and explore the social and psychological impacts, particularly on children. Findings indicate that divorces conducted outside the legal framework not only violate national laws but also often result in disadvantages for vulnerable parties, especially women and children. In Islamic teachings, while divorce is permissible, it is considered the most detested lawful act by Allah and should only be pursued after all efforts at reconciliation have failed. National legal provisions echo this perspective by emphasizing mediation and the principle of justice as primary steps in resolving marital disputes. This alignment reflects a harmony between religious norms and state law. Therefore, public awareness of proper legal procedures for divorce needs to be enhanced to protect individual rights and preserve family stability. Strengthening legal education and premarital counseling are effective preventive strategies in this regard.  

This study examines the legal conflict between workers' wage claims and state tax obligations in bankruptcy proceedings under Indonesian law, focusing on the constitutional imperative to prioritize workers' rights. The Introduction contextualizes the tension between Article 95(4) of the Labor Law, which mandates wage prioritization, and tax legislation granting precedence to state claims, highlighting the landmark Constitutional Court Decision No. 67/PUU-XI/2013 that affirmed workers' constitutional rights to timely wages. Employing a Method of normative legal research, the analysis integrates statutory and case approaches, reviewing laws on bankruptcy (UU No. 37/2004), labor rights, and taxation, alongside judicial decisions and international frameworks like ILO Conventions No. 100 and 111. Results reveal that while the Constitutional Court’s decision established workers’ absolute priority over tax claims, regulatory disharmony persists due to conflicting provisions in the Tax Law (UU KUP) and the 2020 Job Creation Law (UU Cipta Kerja), which ambiguously subordinates tax claims only to secured creditors. Discussion underscores the necessity for legal synchronization to align labor and tax regulations, ensuring compliance with Gustav Radbruch’s principles of legal certainty and Hans Kelsen’s normative hierarchy. The study advocates legislative reforms to codify workers’ priority in bankruptcy, drawing parallels with Malaysia’s Employment Act 1955 and France’s AGS system, which institutionalize wage protection. By addressing regulatory contradictions, Indonesia can harmonize constitutional mandates with fiscal policies, balancing social justice and economic stability.

The provision of sustenance (nafaqah) is a crucial aspect of family life that is strongly emphasized in Islamic teachings. This study aims to explore the urgency of nafaqah through a thematic approach to authentic (ṣaḥīḥ) hadiths that address the obligation of financial support, viewed from legal, ethical, and social perspectives. Using the maudhū‘ī (thematic) method, this research collects and analyzes ṣaḥīḥ hadiths from major compilations such as Ṣaḥīḥ al-Bukhārī and Ṣaḥīḥ Muslim to gain a comprehensive understanding of Islamic principles regarding nafaqah. The findings reveal that providing sustenance is not only a legal duty of the husband, but also a sign of faith, compassion, and a means of maintaining social stability. This study highlights the importance of a proper understanding of nafaqah in Islam as a foundation for building a harmonious and God-pleasing family.

This study provides a comprehensive synthesis of ten SINTA-accredited journal articles (levels 1–3) published from 2019 to 2024, examining how a low-interest-rate policy environment affects corporate capital structure in Indonesia. We focus on internal determinants (profitability, firm size, asset composition) versus external factors (market interest rates) in shaping firms’ debt ratios. The meta-analysis results indicate that although low interest rates statistically encourage higher leverage (average coefficient +0.28), internal firm characteristics remain the dominant drivers of capital structure decisions. Approximately 80% of studies report that more profitable firms tend to reduce debt ratios, consistent with the pecking order theory. In the post-pandemic context, low rates initially facilitated cheap borrowing, but heightened economic uncertainty underscores the need for managers to align funding strategy with each firm’s risk profile. The study draws practical implications: financial managers should calibrate capital structure in line with profitability and market volatility, while regulators should monitor corporate debt growth to safeguard financial stability. The findings also suggest directions for future research on how evolving macroeconomic conditions influence corporate finance in Indonesia.
