The rapid development of digital technology has significantly transformed financial transaction systems, including the use of securities. Conventional securities, which traditionally function as instruments of payment, evidence, and transfer of rights, face various challenges such as document forgery, loss, and administrative inefficiency. These conditions have encouraged the digitalization of securities, requiring adjustments within the Indonesian legal framework. This study aims to analyze the transformation of securities from conventional forms to digital formats within the perspective of Indonesian law and to assess the adequacy of existing regulations in addressing such developments. The research employs a normative juridical approach by examining primary legal materials in the form of statutory regulations and secondary legal materials consisting of legal literature and previous studies. The findings indicate that although electronic documents have been legally recognized as valid evidence, there is no specific and comprehensive regulation governing digital securities. Consequently, legal uncertainty remains regarding the transfer of rights, evidentiary strength, and legal protection for holders of digital securities. This study is expected to contribute conceptually to the development of adaptive legal regulations that ensure legal certainty and protection in the context of modern digital transactions.

One of the long-standing marriage traditions in the Ende community is the ana ale marriage tradition. Ana ale marriage is a form of marriage based on an agreement between the parents of the man and woman, as well as a long-established good relationship between both parents. This research was conducted in Tiwu Tewa Village, Ende Timur District, Ende Regency. This research aims to understand the fundamental values contained in marriage as viewed from customary law, the process of implementation and its legitimacy, as well as the obstacles in the implementation of the ana ale marriage. The method used is empirical legal research with a qualitative approach, which includes interviews and literature study. The research results show that the fundamental values contained in the ana ale marriage, as viewed from customary law, consist of sacred and spiritual values, responsibility and commitment values, social and mutual assistance values, and adherence to customs. The process of implementing the ana ale marriage includes Ru’u Tu Jaga Rara, Janji, Puzi Ru’u, Teo Zambu, Bou Engga, Mai Tu Gega Padha, Tu Ngawi, Teke Ngara, Dari Nikah, Tu Ana. Meanwhile, the marriage is considered valid at the Tu Ana ceremony. The obstacles faced in the ana ale marriage include economic factors and the occurrence of clandestine marriages by the female party.

Indonesia's maritime security faces increasingly complex challenges due to the rise of hybrid threats that combine traditional and non-traditional elements. One of the main threats is the shadow fleet, operating covertly with unregistered ships, evading detection, and exploiting weaknesses in maritime surveillance to engage in illegal activities such as smuggling, illegal transshipment, and unlawful exploitation of natural resources. This phenomenon exacerbates Indonesia's maritime security situation, particularly in strategic areas like the Natuna Sea and the Sunda Strait, which are vulnerable to geopolitical conflicts and overlapping territorial claims. Additionally, transnational crimes such as piracy, drug trafficking, and human trafficking further undermine security in Indonesian waters. To address these threats, Indonesia needs to strengthen its maritime surveillance capacity by adopting advanced technologies such as early detection sistems and the Automatic Identification Sistem (AIS), as well as enhancing coordination between maritime agencies like Bakamla and the Indonesian Navy (TNI AL) to improve responses to harder-to-detect threats. Moreover, international cooperation with neighboring countries and regional maritime organizations like ASEAN must be bolstered to tackle cross-border threats. Strengthening surveillance, modernizing technology, and fostering more integrative maritime diplomacy will be crucial in safeguarding Indonesia's maritime sovereignty and ensuring the stability of this increasingly strategic maritime region.

The implementation of local democracy in Indonesia faces challenges when the electoral and procedural mechanisms regulated in modern village administration are not fully in line with the socio-cultural traditions of indigenous communities. Many villages still strongly uphold the values, norms, and authority of traditional institutions that have historically regulated communal life, including in terms of leadership legitimacy. Tension between formal democracy and customary values arises when the village political process is perceived as not reflecting the cultural identity of the community. This situation creates a need to understand how the integration of customary institutions can strengthen the legitimacy of village leaders in the local democratic system. This study uses a literature review method with a content analysis approach because the study focuses on the concept of the role of customary institutions in strengthening local democracy and the legitimacy of village leadership. This method allows researchers to explore theories and compare previous findings to form a systematic understanding. The research data comes from 19 secondary sources in the form of scientific books and journal articles published between 2016 and 2025 that are relevant to the themes of customs, village governance, community participation, and local leadership. The search was conducted using the Publish or Perish application with purposive sampling techniques to select sources directly related to the main research issue. This study concludes that the integration of traditional institutions into local democracy produces a model of village leadership that is legally strong and culturally rooted. This integration provides a basis for strengthening local democracy based on cultural wisdom, thereby supporting village development.

This study analyzes the implementation of cultural preservation policies in Lebak Regency in the context of the Seren Taun tradition as part of efforts to maintain local wisdom and sustainable development. The approach used is qualitative with a case study method, through interviews, observations, and documentation studies of local governments, traditional leaders, and the Kasepuhan Citorek community. Data analysis was carried out using the Miles and Huberman model, including data reduction, data presentation, and conclusion drawn. The results of the study show that the implementation of cultural preservation policies in Lebak has been regulated through Regent Regulation Number 435 of 2022 concerning Regional Cultural Promotion, which emphasizes the importance of indigenous peoples' participation. The implementation of this policy is analyzed using Edwards III's theory, which includes communication, resources, disposition, and bureaucratic structure. The Seren Taun tradition has proven to play an important role in strengthening cultural identity, fostering social solidarity, maintaining food security, and teaching ecological awareness. However, challenges such as budget constraints, low cultural documentation, and shifting values of the younger generation remain major obstacles. This research emphasizes that synergy between the government, customary institutions, and communities is the key to the success of sustainable and inclusive cultural preservation in Lebak Regency.

This study aims to explore Generation Z's adaptation to traditional values, particularly the Balinese language sor singgih in Catur Wangsa, amid social changes driven by globalization and technological advancements, from the perspective of interpersonal communication. The phenomenological approach in qualitative research is the research method used, with three data collection techniques: participant observation, unstructured interviews, and documentation. This study also uses source and technique triangulation as a data validity technique. The research informants are members of Generation Z from the five castes in Bali: Brahmana, Ksatria, Weisya, and Sudra. Research conducted across eight districts and cities in Bali indicates that Generation Z is beginning to shift its interpersonal communication patterns. Although they still uphold traditional values of politeness and social norms, Generation Z emphasizes equality and openness in their daily interactions. The generation Z that continues to use the Balinese language is segmented by social context, emotional closeness, and communication situations, rather than solely by caste differences. Furthermore, this study's findings show that the caste system is seen more as a cultural identity than a social boundary. The implications of this research emphasize the importance of preserving the values of Balinese local wisdom in the form of adaptive, egalitarian communication that is relevant to the development of the younger generation in the digital age.

The background of this research aims to determine and analyze judges' perspectives on the application of customary law in resolving criminal cases at the Padangsidimpuan District Court. Customary law is an unwritten legal system that exists and develops within society and is often used as a consideration in deciding cases related to local values ​​and cultural wisdom. In the context of Padangsidimpuan society, which still strongly upholds customs and traditions, customary law often serves as a means of resolving social conflicts before they enter the formal legal realm. The research method used is empirical juridical, with data collection techniques through direct interviews with judges and document studies of several relevant court decisions. The results indicate that most judges at the Padangsidimpuan District Court view customary law as a complementary instrument to positive law, particularly in minor criminal cases with social and familial dimensions. Judges strive to consider customary values ​​to achieve substantive justice, without neglecting the principle of legality and statutory provisions. However, the application of customary law cannot replace positive law in its entirety; rather, it serves as a moral and social value that strengthens the community's sense of justice.

This research explores the significant role of cultural institutions in overseeing and enforcing laws based on local wisdom in Indonesia, a nation characterized by its rich cultural diversity. The purpose of this study is to analyze how cultural institutions, particularly customary law bodies, can help integrate local traditions and values into the formal legal system, ensuring that laws are more reflective of and responsive to the diverse communities across the country. The study employs a normative approach with a prescriptive method to examine the challenges and opportunities of incorporating local wisdom into national law, particularly in the realm of legal oversight and dispute resolution. The research reveals that, despite constitutional recognition of customary law, its practical implementation within the national legal framework remains hindered by conflicts between customary norms and formal legal structures. Key findings suggest that strengthening the role of cultural institutions in legal processes can enhance both the legitimacy and effectiveness of the legal system, promoting social harmony and fostering justice that resonates with the local context. Ultimately, the study concludes that empowering cultural institutions is vital for creating a legal environment that respects and integrates local wisdom, which will contribute to a more inclusive, fair, and sustainable legal system in Indonesia.

This study aims to analyze the role and optimization strategies of Pecalang Segara in monitoring fishing activities that contribute to coral reef ecosystem degradation in the Traditional Village of Pemuteran, North Bali. Pecalang Segara is a customary security institution that holds social legitimacy and customary authority in maintaining order within coastal areas. This research applies an empirical legal approach using a qualitative descriptive method. Data were collected through field observations, interviews with customary leaders and coastal communities, and a literature review of environmental laws and related regulations. The findings indicate that Pecalang Segara plays a strategic role in supervising fishing activities based on local wisdom, particularly in preventing destructive fishing practices that damage coral reefs. However, the effectiveness of this role remains limited due to insufficient technical capacity, low environmental legal awareness, and weak integration between customary law and formal legal systems. The study highlights the importance of strengthening Pecalang Segara through environmental education, regulatory-based monitoring training, and institutional coordination with local government authorities. The integration of customary law and national environmental law is expected to establish a sustainable community-based marine monitoring model capable of effectively protecting coral reef ecosystems and supporting environmental governance in coastal areas.

This study examines the implementation of the Manak Salah tradition in Padang Bulia Customary Village from the perspectives of legal certainty and human rights protection. Manak Salah is a customary practice associated with the birth of opposite-sex twins, which in Balinese Hindu cosmology is considered a sacred event that may disrupt the balance between the sekala and niskala realms, thereby requiring purification rituals. Although the contemporary practice of this tradition has become more humane and no longer involves social exclusion, its regulation remains unwritten and has not been formally codified in the village’s Awig-awig (customary law). This condition creates the risk of multiple interpretations, legal uncertainty, and insufficient protection of the rights of children and affected families. This research employs an empirical juridical method with a qualitative approach, using interviews with customary leaders, field observations, and document analysis of statutory regulations and customary legal sources. The findings reveal that the absence of written norms causes the implementation of Manak Salah to rely heavily on the discretion of customary authorities, leading to potential inconsistency and normative vulnerability. This study emphasizes the urgency of codifying the Manak Salah tradition into the Awig-awig as a form of customary law reform aimed at ensuring legal certainty, strengthening institutional accountability within customary villages, and harmonizing customary law with Bali Provincial Regulation No. 4 of 2019 and fundamental human rights principles.

The purpose of this study is to determine how the social behavior of the Margoagung Village Community, especially Ngino Hamlet, in preserving local wisdom inherited from the ancestors of Mbah Bregas, especially in building community harmony. This field research was conducted using a qualitative descriptive method. This research was conducted by taking a case study in Ngino Hamlet, Margoagung Village, Seyegan Sub-district, Sleman Regency from June to July 2025. The informants of this study were the leaders, committees, traditional figures and all parties involved and witnessed directly the Merti activities of Margoagung Village. Data collection was carried out through observation, interviews and documentation. Data analysis was carried out through four stages, namely: data documentation, data reduction, data presentation, and drawing conclusions/verification. The study findings show that the entire series of Merti activities of Mbah Bregas Village, Margoagung Village build community harmony through participation, cooperation and mutual cooperation without distinguishing religion, ethnicity, race, social strata and profession.

This study explores the importance of protecting the Geographical Indication (GI) of Lamsi Tobacco from Temanggung to safeguard its authenticity and maintain product quality, in accordance with Law Number 20 of 2016 on Marks and Geographical Indications. Lamsi Tobacco is known for its distinctive taste, aroma, and quality, which are influenced by the geographical conditions of Temanggung as well as traditional cultivation practices passed down through generations. However, without legal protection, the authenticity and reputation of this product risk being diminished due to counterfeiting or unauthorized use of its name. The research method employed is normative juridical, which focuses on library research or secondary data by viewing law as a set of written norms enacted by authorized institutions. To strengthen the analysis, this study is also supported by a socio-legal approach that combines legal studies with social sciences so that law is understood not only as written norms but also as a practice that lives within society. The findings indicate that Lamsi Tobacco meets the criteria for Geographical Indication as stipulated in Law No. 20 of 2016 Protection through Geographical Indications not only plays a role in preserving the authenticity and quality of the product but also generates positive economic and social impacts for the community, particularly farmers. Nevertheless, several obstacles remain, such as low legal awareness, administrative difficulties, and the absence of a strong managing institution. Therefore, coordination between the central government, local government, farmer associations, and the community is necessary to realize effective legal protection. Through the registration and protection of Geographical Indications, Lamsi Tobacco is expected to maintain its reputation, increase competitiveness in the market, and make a tangible contribution to the welfare of the Temanggung community as well as the preservation of local culture.

This study examines the concept of women's leadership from an Islamic and Catholic perspective and how religious values ​​influence the acceptance and legitimacy of women's leadership in the public sphere. Using a qualitative approach using a desk study method, this study analyzes religious texts, scientific literature, and case studies of the leadership of two Southeast Asian women: Megawati Soekarnoputri in Indonesia and Corazon Aquino in the Philippines. The results show that both Islam and Catholicism have complex histories and interpretations of women's roles in leadership. While conservative and patriarchal readings exist within both traditions, there is also interpretive space that allows women to emerge as leaders. The leadership of Megawati and Aquino demonstrates that women are capable of leading with distinctive styles rooted in values ​​of spirituality, morality, and service. Both demonstrate a non-confrontational yet effective leadership approach, which simultaneously opens up space for reinterpreting women's roles in religion and politics. Thus, women's leadership is not a deviation from religious teachings, but rather part of the socio-religious dynamic that demands inclusivity and equality.

This study aims to analyze the perceptions of Generation Z members of the Toba Batak ethnic group in Pegagan Julu VI Village, Sumbul District, Dairi Regency, regarding the symbolic meaning of the tradition of giving manuk naniatur (a traditional gift) and the shifting meaning or function of this tradition according to Generation Z. The method used was qualitative with a descriptive approach. Data were collected through observation, interviews, and documentation. The results indicate that the tradition of giving manuk naniatur is still routinely practiced and has become a local custom. Most Generation Z members value this tradition as an important part of their cultural identity and ancestral heritage, although not all understand its symbols deeply. This tradition is seen as an expression of love and gratitude to God, as well as a sign of blessing, hope, encouragement, and strength for children or families who have migrated. However, there has been a shift in meaning in Generation Z's perspective, from the tradition previously seen as a symbol of respect and spiritual bonding to now being seen more as a cultural identity and shared values ​​that must be maintained. This study illustrates the dynamics of traditional cultural preservation and adaptation to the changing times among the younger generation of the Toba Batak ethnic group.

Inheritance law in Indonesia is pluralistic because it is influenced by three legal systems, namely customary law, Islamic law, and western civil law (Burgerlijk Wetboek) which is a legacy of the Dutch colonial era and divides the population based on legal classes. This diversity of legal systems also influences inheritance practices in Chinese society which traditionally adheres to a patrilineal system, where sons are prioritized over daughters in the distribution of inheritance. This study aims to analyze the inheritance law regulations for Chinese society, the development of inheritance practices that occur, and the legal considerations used by judges in the Supreme Court Decision Number 147K/Pdt/2017. The research method used is normative-empirical legal research with a statutory approach, cases, and legal identification, as well as assessing the effectiveness of legal implementation through literature studies and interviews. The results of the study indicate that the Supreme Court decision confirms the equality of inheritance rights between sons and daughters. This marks a shift in the Chinese inheritance system from patrilineal customs to the application of the provisions of the Civil Code, which upholds the values ​​of justice and gender equality.

The rapid development of Islamic banking in Indonesia faces significant challenges in maintaining liquidity and profitability amidst dynamic capital market conditions. The urgency of this study arises from the need to examine whether traditional financial ratios, such as the Financing to Deposit Ratio (FDR) and Return on Equity (ROE), play a decisive role in influencing investment decisions, which are proxied by the Price to Earning Ratio (PER). The main objective of this research is to empirically test the effect of liquidity and profitability, both partially and simultaneously, on investment decisions in Islamic commercial banks listed on the Indonesia Stock Exchange during the 2021–2025 period. This study adopts an associative design with a quantitative approach, utilizing secondary data from financial reports obtained from the IDX, and analyzed using multiple linear regression on 68 observation samples. The findings reveal that neither liquidity nor profitability significantly influence investment decisions, either partially or simultaneously. These results suggest that investors in the Islamic banking sector tend to prioritize non-financial factors such as sharia compliance, governance, macroeconomic conditions, and ESG trends, rather than conventional financial indicators. In conclusion, this research extends the understanding of the limitations of Signaling Theory in the sharia context and recommends the development of a more holistic investment evaluation model. Future studies are encouraged to incorporate non-financial variables for a more comprehensive analysis.

This study examines the application of the ultra petita principle in decisions of the Constitutional Court of the Republic of Indonesia, focusing on the case study of Decision Number 90/PUU-XXI/2023. The ultra petita principle is classically understood as a prohibition for judges to rule beyond what is explicitly requested by the parties to the case. However, in practice, the Constitutional Court often uses this principle flexibly to ensure substantive justice and the effective protection of citizens' constitutional rights. This shows how constitutional adjudication in Indonesia tends to prioritize substantive justice over procedural limitations. This thesis aims to analyze the legal basis used by the Constitutional Court when deciding ultra petita cases, while also examining the resulting legal implications for the administrative system of lawmaking in Indonesia. Using a normative legal approach, this study finds that the Constitutional Court positions itself as the sole interpreter of the constitution with progressive authority. In this sense, the Court's decisions may expand its role beyond the traditional boundaries of judicial authority. However, the Constitutional Court's ultra petita practice has the potential to raise concerns about judicial overreach. Ultra petita decisions not only resolve constitutional disputes but also have the potential to create new legal norms that can directly influence the legislative process and even change the structure of national law. Such outcomes raise the question of how to maintain a balance between judicial activism and legislative supremacy. Therefore, it is crucial to establish clear legal boundaries to ensure the Court remains within the constitutional framework, upholds the principle of checks and balances, and prevents conflicts of authority between branches of state power. Therefore, this research contributes to the academic understanding of the dynamics of the Constitutional Court's authority and the urgency of strengthening the rules of the game in maintaining harmony in the Indonesian state system.

The development of information and communication technology (ICT), particularly the use of Artificial Intelligence (AI), the Internet of Things (IoT), and big data, has transformed Indonesia's national security threat landscape. Threats that previously focused on traditional military aspects have now shifted to non-traditional cyber threats, such as cyberattacks, digital espionage, and infrastructure sabotage. According to PROXSIS IT GRC data, in 2024, more than 19 million cyberattacks were recorded against websites in Indonesia. While this figure is a decrease compared to the previous year, this trend is thought to reflect a shift towards more structured and organized tactics by threat actors. In response, the Indonesian government established the National Cybersecurity Action Plan 2024–2028 as a strategic guideline. Furthermore, cyber diplomacy is being promoted through bilateral and multilateral cooperation, for example through the signing of memorandums of understanding (MoUs) with the UK and Kaspersky. This cooperation includes the exchange of intelligence information, strengthening human resource capacity, raising public awareness regarding cybersecurity, and protecting critical information infrastructure. This study uses non-traditional security theory and defense diplomacy to analyze the strategies, challenges, and prospects of Indonesia's cyber policy. The analysis demonstrates that cyber defense diplomacy plays a crucial role as an instrument for integrating technology, regulation, and international collaboration in safeguarding digital sovereignty. In addition to strengthening threat detection and mitigation capabilities, this diplomacy also builds networks of trust with partner nations, which is essential amidst the increasing complexity of global threats. Therefore, in the era of digital globalization, full of interconnections, cyber defense diplomacy serves not only as a national protection tool but also as Indonesia's contribution to global cybersecurity stability. This effort prioritizes synergy between technological innovation, law enforcement, and sustainable international cooperation.

This study aims to examine the strategic role of the Cieurih Community Health Center in increasing public awareness of healthy lifestyles, particularly in the Cipaku Sub-district. Employing a qualitative descriptive approach, data were collected through observation, in-depth interviews with key stakeholders, and documentation of program activities. The collected data were analyzed using three stages: data reduction, data presentation, and drawing conclusions with verification to ensure validity. The analysis focuses on three main dimensions of the Health Center’s role: (1) Interpersonal Role, which involves direct interaction with the community to build trust, encourage participation, and foster behavioral change; (2) Informational Role, which encompasses the dissemination of accurate health information, educational campaigns, and correction of misinformation; and (3) Decisional Role, which relates to planning, implementing, and evaluating health programs in response to local needs.The findings reveal that the Cieurih Community Health Center has made significant contributions to raising awareness and promoting healthy living practices through these roles. Initiatives such as health counseling, mobile clinic services, and collaborative activities with community leaders have shown positive influence. However, the study also identifies persistent challenges, including low levels of community participation, insufficient financial and human resources, and the strong influence of traditional cultural practices and misinformation that hinder optimal outcomes. To address these obstacles, adaptive strategies are necessary. Recommendations include the development of personalized approaches tailored to the socio-cultural context, the use of innovative communication methods such as social media and visual storytelling, and the strengthening of cross-sectoral collaboration with educational institutions, religious leaders, and local government agencies. These measures are expected to enhance community engagement, improve the accuracy and reach of health information, and sustain the long-term impact of health promotion programs.
