The digital transformation of the Indonesian judicial system through the implementation of e-court and e-litigation necessitates a redefinition of conventional evidentiary laws, which have historically been governed by the Herziene Inlandsch Reglement (HIR) and the Rechtreglement voor de Buitengewesten (RBg). This research aims to analyze the evidentiary strength of electronic documents as expanded means of proof in civil proceedings and to identify the challenges regarding their implementation. The research method employed is normative legal research using a statutory approach and a conceptual approach. The findings indicate that based on the principle of functional equivalence, electronic documents hold a legal status equivalent to paper-based documents, provided they meet the requirements of integrity, accessibility, and authenticity through certified electronic signatures as mandated by Law Number 1 of 2024 concerning Electronic Information and Transactions. The evidentiary strength of an electronic document may reach the level of conclusive evidence, similar to an authentic deed, if supported by a reliable electronic system. However, implementation still faces technical hurdles concerning metadata verification and limited human resource competency within the judiciary. This research recommends the urgent need for a new codification of civil procedural law and the standardization of digital forensic procedures in trials to ensure legal certainty and justice for all parties in the digital era.

The enactment of Indonesia's Law Number 20 of 2025 on the Code of Criminal Procedure (KUHAP 2025), effective January 2, 2026, introduces a paradigmatic shift in the coordination between investigators and public prosecutors: Article 58 mandates active coordination from the investigation stage, fundamentally departing from the sequential-passive model of the former KUHAP, while Article 70 imposes a strict seven-day deadline for indictment drafting after case files are declared complete. This study examines two interconnected questions: (1) how the legal framework governing investigator–prosecutor coordination is structured under KUHAP 2025 and related legislation; and (2) how that framework is implemented in practice at the Purwakarta District Prosecutor's Office. A normative–empirical mixed-method design was employed, integrating statutory, conceptual, and case-study approaches. Data were gathered through in-depth interviews with prosecutors and investigators at Purwakarta District Prosecutor's Office and Purwakarta Police Resort, case document analysis, and field observation. The theoretical framework combines Lawrence M. Friedman's Legal System Theory and Soerjono Soekanto's Law Enforcement Theory. Findings reveal that KUHAP 2025 delivers substantial normative advancement yet harbours three critical regulatory gaps: the absence of binding technical protocols for implementing mandatory active coordination, the lack of uniform and measurable case-file completeness standards, and no formal mechanism for resolving institutional disagreements on legal interpretation. On the ground, coordination at Purwakarta still operates under the old sequential-passive pattern despite the new law: case-file returns (P-19) remain frequent, driven primarily by absent expert testimony, insufficient factual narration in examination records, and mismatches between charged articles and legal facts. A Friedman–Soekanto diagnostic reveals simultaneous dysfunction across all three legal system components substance, structure, and legal culture with the entrenched 'waiting culture' between the police and the prosecution identified as the most resistant obstacle to reform.

Public Wi-Fi services (Wifi_STAKat) at the State Catholic College of Pontianak continue to face technical issues, such as network speed and connection stability, as well as non-technical challenges, including the responsiveness of administrators to user complaints. This study aims to analyze user satisfaction based on the five Servqual dimensions and to map improvement priorities using the Importance–Performance Analysis (IPA) method. The relationship between Servqual and IPA is explained by mapping GAP values (perception–expectation) into the four IPA quadrants to determine the urgency level of service improvements. A 4-point Likert scale was used to avoid neutral responses and strengthen the clarity of respondents’ perceptions. The results show that all dimensions have negative GAP scores, particularly responsiveness and reliability, which are directly related to technical indicators (speed, stability, coverage) and non-technical factors (responsiveness to complaints, ease of access. The study recommends integrating an IT-based monitoring system and increasing network capacity to improve service quality.

The rapid digitalization in Indonesia, reaching 180 million active social media users, has not been accompanied by adequate security system resilience, thereby triggering massive data breach risks. This study aims to analyze the privacy navigation mechanisms of the digital society as an instrument for mitigating information leaks. The method used is descriptive qualitative with a literature study (library research) approach, which examines primary and secondary literature related to regulations, digital behavior, and user psychological factors. The research findings indicate that privacy navigation in the digital era has not operated optimally due to the dominance of social existence needs, which triggers the privacy paradox phenomenon. Although users possess knowledge regarding cyber risks, the desire for social validation through self-disclosure often overrides technical protection logic. The practice of using secondary accounts (second accounts) was found to be a form of manual navigation, yet its effectiveness remains dependent on individual digital literacy. The implications of this research emphasize that mitigating information leaks requires the integration of critical user awareness, platform governance transparency, and consistent law enforcement through the PDP Law. Digital awareness must transform into reflexive protective behavior to maintain informational sovereignty in cyberspace.

This study analyzes the regulatory gaps in digital forensics regarding the handling of natural resource crimes and the state’s constitutional responsibilities following the enactment of Law No. 1 of 2024. Modern natural resource crimes, such as illegal logging and illegal mining, have evolved to leverage digital technology, leaving complex electronic traces in the form of GPS data and digital documents. However, Indonesia still faces procedural gaps in the Criminal Procedure Code (KUHAP), unclear technical standards (SNI 27037:2014 is voluntary in nature), and conflicts between the Information and Electronic Transactions Law (UU ITE) and sectoral NRE laws. This normative legal study employs legislative, conceptual, and case-based approaches. The research findings indicate that the absence of digital forensic authentication standards has fatal implications, as evidenced by the Sidoarjo District Court Decision No. 488/Pid.B/2024/PN Sda, which rejected electronic evidence. This situation constitutes state negligence (staatsverzuim) that violates Article 1(3) and Article 33(3) of the 1945 Constitution of the Republic of Indonesia. The study recommends the development of standard digital forensic procedures, the acceleration of ISO/IEC 17025 laboratory accreditation, and the harmonization of sectoral regulations

This study is motivated by the dynamic changes in digital consumer behavior in e-commerce, particularly in the purchase of electronic products through the Tokopedia platform. The study aims to analyze and synthesize the influence of online reviews and product ratings on purchase decisions using a systematic literature review approach. The method involves a comprehensive examination of global and local scientific literature, with a focus on peer-reviewed journals and empirical studies published between 2021 and 2026. The findings indicate that online reviews and product ratings are capable of reducing consumer uncertainty as well as the functional risks associated with electronic products. Empirical evidence over the past decade suggests that high ratings can build initial confidence in brand quality, while detailed reviews provide crucial technical validation for potential buyers. Overall, these two indicators work synergistically to strengthen consumer trust and serve as key determinants in the final stage of the purchasing decision. The implications suggest that e-commerce platforms and sellers need to prioritize the management of user-generated content and maintain transparency in reputation to remain competitive in a market increasingly reliant on the credibility of online information.

Zakat and taxation are two important instruments in the life of society and the state, both of which aim to improve social welfare. However, in practice, the integration of zakat and taxation in Indonesia has not yet been fully realised, meaning that the potential of zakat as part of fiscal policy has not been optimally utilised. This study aims to examine the status of zakat within the legal system and public policy, the form of its integration into the tax system, and the various obstacles encountered in its implementation. This study employs a normative legal methodology using legislative, conceptual, and analytical approaches, and utilises secondary data analysed qualitatively. The research findings indicate that zakat has been recognised within the national legal system; however, it is still viewed as a religious obligation that coexists alongside taxation as a state obligation. The current integration remains limited to reductions in taxable income and has not yet demonstrated comprehensive coherence within fiscal policy. Furthermore, its implementation continues to face various obstacles from legal, institutional, technical, and fiscal perspectives, meaning it has not yet been effectively implemented.

This study aims to analyze the implementation of the Bravo PUPR Online attendance system in improving the work discipline of Civil Servants (ASN) at the National Road Implementation Center of East Nusa Tenggara. The research focuses on punctuality of attendance, consistency in fulfilling working hours, task completion, compliance with attendance procedures, alignment between recorded data and actual conditions, and acceptance of consequences for violations. The study employs a qualitative approach with data collection techniques including observation, documentation, and interviews with leaders, system operators, and ASN as direct users. The results indicate that the implementation of the Bravo PUPR Online attendance system has improved administrative order in attendance and increased ASN awareness of time discipline. However, work discipline has not been fully optimal, as several issues remain, such as inconsistent attendance, suboptimal fulfillment of working hours, and discrepancies between attendance data and actual field conditions. In addition, technical constraints such as internet connectivity and GPS accuracy, as well as behavioral factors like negligence and lack of supervision, also affect system effectiveness. In terms of compliance, the Bravo system integrated with e-HRM is considered effective in detecting violations and enforcing strict consequences, ranging from warnings to administrative sanctions. This demonstrates that the attendance system functions not only as a recording tool but also as an instrument for monitoring discipline.

The development of digital technology and internet penetration are driving changes in consumer behavior and demanding that MSMEs not only adapt but also understand the operational motives and marketing channel integration strategies to face competition in the digital era. This study aims to examine the operational motives and technical adaptation processes of Micro, Small, and Medium Enterprises (MSMEs) in Bali in integrating online and offline marketing channels through an omnichannel strategy to respond to intense market competition in the digital era. This descriptive qualitative research uses a multiple case study approach in three different MSME sectors: goods maintenance services, creative services, and fashion retail. Data collection was conducted through direct observation, in-depth interviews, and a review of digital activities, then analyzed through single-case and cross-case stages. The results show that MSMEs optimize digital channels as instruments to expand reach and trigger consumer emotional engagement through a visual storytelling approach, while physical stores are crucially maintained as points of sensory validation. Functional integration has been proven to accommodate the shift in consumer behavior towards a hybrid decision-making pattern. In this pattern, consumers conduct information searches and initial evaluations online, but tend to shift to offline interactions to validate quality and finalize transactions to minimize purchase risk. In conclusion, cross-channel operational synergy has proven essential in boosting the competitive advantage of MSMEs.

A MSMEs in Indonesia has recently contributed to national exports by 15,7%  compared with Thailand that has reached 29 %, so substantial revision are required to make sure that increasing contribution which ultimately will give positive impact toward the economy overall, because almost 90 % of human resource work in MSMEs sector with nature resource and other plentiful resources. The main problem that is commonly found by MSMEs is to optimize the available resources as well as fulfill the required standards that have established and required regulation in order to ensure the resulting product is accepted by the market and to comply with the regulation that has been established by the regulator. Indonesia as the second biggest country in the world has biodiversity certainly offers benefits that hard to imitate by other country in producing biopharmaceutical plants product, therefore it offers competitive potential in the global market, however market penetration by MSMEs biopharmaceutical plants sector commonly discontinued regarding with technical barriers to trade (TBT). This study is based on a case study that aims to analyze main challenges in fulfillment of international certification and to formulate adaptation strategy for MSMEs. By conducting through a descriptive qualitative method with case study approaches, the result of study indicates that high compliance costs,  registration procedural complexity from the source and destination country, as well as the inconsistency of raw material quality became the main barriers. The proposed strategy including group certification model, CPOTB standard harmonization, and the utilization of integrated government assistance schemes will provide real contribution in assisting MSMEs fulfilling global market requirements.

. Digital transformation in public administration has become a strategic agenda in modern bureaucratic reform aimed at improving effectiveness, efficiency, transparency, and the quality of public services. This study aims to analyze the digital transformation of public administration through a comparative study between Indonesia and South Korea, particularly in the implementation of digital government. The research employs a qualitative method with a comparative study approach and is supported by library research through the collection of secondary data from scientific journals, international institutional reports, government policy documents, and relevant previous studies. Data analysis was conducted descriptively and comparatively using the approaches of Digital Era Governance (DEG), Institutional Theory, New Public Management (NPM), and Socio-Technical Systems Theory. The findings indicate that South Korea has successfully developed an integrated digital government through consistent national policies, strong data interoperability, high bureaucratic capacity, adaptive organizational culture, and equitable digital infrastructure development. Meanwhile, Indonesia is still in the transition stage from e-government to digital government and faces various challenges, such as inter-agency system fragmentation, low data interoperability, unequal digital infrastructure, limited civil servant competencies, and bureaucratic resistance to change. This study concludes that the success of digital transformation in public administration is determined more by institutional strength and bureaucratic reform than merely by technology adoption. Therefore, Indonesia needs to position digital transformation as a comprehensive state reform agenda in order to create a modern, responsive, and public service-oriented government.

Flooding in Aceh has become a recurring phenomenon that cannot be understood solely as a natural disaster but also as a result of human activities within modern society. This study aims to analyze flooding in Aceh through the perspective of Ulrich Beck’s risk society theory, focusing on how modernization, environmental change, and development policies contribute to the production of risk. This research uses a literature review approach by examining scientific articles published between 2021 and 2026 from indexed national and international journals. The analysis was conducted thematically to identify patterns, similarities, and research gaps. The findings show that natural factors such as high rainfall and atmospheric conditions act as primary triggers, while human activities including land-use change, river sedimentation, and ineffective policies significantly intensify flood risks. Flooding is therefore categorized as a manufactured risk produced by modern development processes. In addition, the impacts are not limited to ecological damage but also affect social and psychological conditions of society. These results indicate that floods should be understood not only from a technical perspective but also from a social perspective. The study implies that flood management requires a comprehensive approach integrating environmental sustainability, social awareness, and evidence-based policy to reduce both the impact and sources of risk in a sustainable manner.

The shift in the international political order from a unipolar to a multipolar system has created increasingly complex global security dynamics and the potential for conflicts among states. This condition requires improving international political literacy among civil society, particularly Indonesian youth, so they can critically understand and respond to geopolitical transformations. In response to this urgency, this Community Service Program (PKM) aimed to enhance students’ global issue literacy through the Foreign Policy Community of Indonesia (FPCI) Goes To School (FGTS) 5.0 program themed Conflict & Military. The activity was conducted on April 6, 2026, involving 40 eleventh-grade students at SMA Negeri 97 Jakarta. The implementation method combined interactive lectures with popular culture references to make the material easier for teenagers to understand. Evaluation was conducted through pre-tests and post-tests in the form of multiple-choice quizzes. The material covered the concept of United States national interests, the Board of Peace (BoP) security initiative, Realism Theory, and the conflicts involving the United States, Israel, and Iran. The evaluation results showed that students had strong understanding of popular global issues but limited comprehension of technical aspects related to international institutions, such as the role of the International Atomic Energy Agency (IAEA). Therefore, future international political literacy programs should focus more on strategic and technical issues that are less familiar to the public.

The development of digital technology in the Society 5.0 era presents both challenges and opportunities in history teaching, particularly regarding teachers’ ability to integrate technology and adapt to changes in students’ learning styles. This study aims to analyse the challenges faced by teachers and the strategies employed in digital-based history teaching. The method used is a Systematic Literature Review (SLR) employing the PRISMA approach, involving the stages of identification, screening, eligibility assessment, and inclusion of scientific articles published between 2020 and 2025. From the selection process, 25 relevant articles were identified for qualitative descriptive analysis. The findings indicate that teachers’ digital literacy levels remain at a moderate level and are unevenly distributed, thereby affecting the sub-optimal integration of technology into teaching. Furthermore, changes in students’ learning styles which are increasingly technology-oriented require more interactive and contextual pedagogical innovations. On the other hand, the use of digital media has proven capable of enhancing student motivation and learning outcomes, although this is still hindered by limitations in infrastructure and teachers’ technical competencies. The abundance of historical information on the internet also poses challenges regarding the validity of sources, thus necessitating the strengthening of digital literacy and critical thinking. The implications of this research underscore the importance of the ongoing development of teachers’ digital skills, the improvement of educational facilities, and the implementation of innovative teaching models to ensure that history teaching becomes more relevant and effective, and is capable of fostering critical thinking skills in pupils in the digital age.

Homemade food is increasingly dominating the choices of consumers who are oriented towards a healthy lifestyle. However, the belief that self-cooking is synonymous with food safety is not always supported by scientific evidence. This Narrative Review aims to build an in-depth thematic synthesis of the various dimensions of food safety risks that arise in the process of preparing healthy homemade food, ranging from biological and chemical contamination, to human behavioral factors as the main agents of contamination. The study was conducted against seven reputable sources of scientific literature published between 2010–2025, including observational, experimental, cross-sectional, and review studies. Four main themes were identified: (1) risky behaviors in the household kitchen as the dominant factor; (2) unexpected cross-contamination pathways including table salt as a vector; (3) chemical and biological contaminants hidden in "healthy" materials; and (4) evidence-based interventions that have been proven to be effective. This review confirms that homemade food safety is a behavioral issue, not just a technical one, so the intervention approach must be multidimensional and sustainable.

Parking tax collection as part of Specific Goods and Services Tax (PBJT) is an important source for increasing Local Own-Source Revenue (PAD). This policy is based on Law Number 1 of 2022 concerning Financial Relations between the Central Government and Regional Governments and is implemented through Regional Regulation of Bandar Lampung City Number 1 of 2024. This study aims to examine the implementation of parking tax collection as PBJT as well as the supporting and inhibiting factors in its execution. The research employs normative juridical and empirical juridical approaches with a descriptive qualitative method. Data were collected through documentation studies and interviews with the Regional Revenue Management Agency (BPPRD) of Bandar Lampung City as the implementing institution. The results show that the implementation of PBJT on parking services in Bandar Lampung City uses a self-assessment system, where parking operators calculate, collect, report, and remit taxes independently through e-SPTPD and SIMANTAP managed by BPPRD. Supporting factors include clear regulations, the utilization of information technology, growth in the parking sector, and inter-agency support. Meanwhile, inhibiting factors include suboptimal taxpayer compliance, limited human resources within BPPRD, technical issues in the reporting system, and fluctuations in revenue due to seasonal factors. Overall, the implementation of PBJT on parking services has been effective but still requires improved supervision to optimize regional tax revenue.
