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.

This research aims to examine and analyze the phenomenon of speeding and illegal racing, which poses a significant threat to traffic safety within the legal jurisdiction of the Buleleng Resort Police (Polres Buleleng). The study employs empirical legal research methods, gathering primary data through observations and interviews with traffic police officers, alongside secondary data from legal literature and previous studies. The findings indicate that the speeding phenomenon in Buleleng is predominantly carried out by teenagers and young adults, often motivated by social media trends, peer pressure, and the search for identity. This reckless behavior leads to a high rate of traffic accidents, frequently resulting in severe injuries or fatalities. Furthermore, law enforcement efforts by Polres Buleleng face several challenges, including the high mobility of the perpetrators, lack of personnel during specific hours, and low legal awareness among the public. Preventive measures such as counseling in schools and repressive measures like electronic traffic law enforcement (E-TLE) and routine patrols need to be optimized. This study concludes that an integrated approach involving the police, educational institutions, and parents is crucial to mitigating the speeding phenomenon and ensuring traffic safety.

The Labor-Intensive Housing Program is one of the Surabaya City Government’s policies aimed at reducing poverty and unemployment through labor-intensive community empowerment. This study aims to describe and analyze the implementation of the Labor-Intensive Housing Program (RPK) at the Pitstop business unit in Lidah Kulon Village, Lakarsantri Subdistrict, Surabaya City. This study employs a qualitative method with a descriptive approach, utilizing Van Meter and Van’s policy implementation theory. Primary data were collected through interviews and observations, while secondary data were derived from official documents and relevant publications. The results showed that the implementation of the Pitstop Labor Intensive Housing Program has not yet been optimal. In terms of policy standards and objectives, the program’s goals have been clearly defined but have not yet been fully achieved. Regarding resources, the availability of facilities and funding is adequate, but there are still limitations in human resources, particularly skilled technicians in the automotive repair field. Inter organizational communication has taken place but has not been intensive enough to support business sustainability. Characteristics of the implementing agents indicate that the structure of the Labor-Intensive Housing team has been clearly defined; however, implementation in the field has not been optimal due to weak coordination and communication. Economic, social, and political conditions-such as a less-than-strategic business location and high competition from similar businesses-have also contributed to the low number of customers. Meanwhile, the disposition of the implementers demonstrates a positive attitude in supporting the Labor-Intensive Housing program. The Labor-Intensive Housing Program must be supported by professional mechanics through education, certification, and collaboration with the private sector and training institutions to ensure the quality of services. In addition, building public trust, coordination among stakeholders, and intensive support through monitoring and evaluation are key to the success and sustainability of the Labor-Intensive Housing Program.

Terrorism is a serious threat to the security and unity of the Indonesian nation. Events such as the suicide bombing at the Medan Police Headquarters in 2019 show that acts of terror are increasingly complex and require swift and appropriate handling. For this reason, the government passed Law Number 5 of 2018 concerning the Eradication of Criminal Acts of Terrorism as a legal basis that strengthens the authority of the apparatus, including the Gegana Detachment of the Indonesian National Police Mobile Brigade Corps (Brimob), in carrying out counter-terrorism operations. This study aims to determine and analyze how the implementation of Law No. 5 of 2018 is carried out by the Gegana Detachment in the North Sumatra Regional Police area, identify obstacles faced in operations, and formulate strategies to increase the effectiveness of the implementation of the law. The results of the study show that the implementation of this law has been implemented through preventive, preemptive, and repressive approaches, such as sterilization of places of worship, social activities "Love Sunday", security patrols, and anti-terror training simulations. However, implementation in the field still faces various obstacles, including limited modern equipment, lack of cross-agency coordination, and low public participation. Therefore, personnel capacity building, infrastructure modernization, and strengthening inter-agency synergy are needed to achieve more effective counterterrorism efforts in North Sumatra.

This research investigates transparency and accountability in the management of state-owned assets (BMN) at the East Java Regional Police's Logistics Bureau as a step toward enhancing effective, adaptive, and integrity-focused governance in police logistics. The research context arises from the growing public call for transparency and accountability in managing state assets, in line with policies for bureaucratic reform and digitalization in the police logistics framework. This study utilized a qualitative descriptive approach involving in-depth interviews, observations in the field, and analysis of documents. The results show that adopting a unified digital system has enhanced the efficiency of asset management, sped up inventory operations, and reduced the risks of asset misuse. Nonetheless, obstacles persist, such as restricted human resource capacity, data alignment problems, and inadequate performance-based assessments. The conversation emphasizes that effective asset management relies on the implementation of adaptive governance, motivation for public service, and precise performance assessment systems. The research indicates that the integration of digital innovation, professional skills, and a robust commitment to public accountability is crucial for creating transparent and sustainable governance in police logistics

The purpose of the study was to analyze the legality and limits of police repressive actions against protests that resulted in riots. This type of research is normative legal research with a legislative approach, a case approach and a conceptual approach. The analysis used in this study is an analytical descriptive technique. The results of the research show that the law is always used as a guideline in limiting all citizens' behavior to stay on the right path. Protests often lead to riots, destruction of public facilities, attacks on officers, and violations of public order, so that there is a criminal threat for protesters who do not maintain order and security. The regulation of police repressive actions in protests that result in chaos still needs special refinement in the context of protests, among which the substance of repressive actions must also harmonize technological developments and digitalization in security maintenance. The rules need to be updated by adding objective indicators of threats, public accountability mechanisms, transparent documentation obligations, measurable proportionality standards, and room for recovery for victims of abuse of power.

The issuance of billboard installation permits is part of local government authority in regulating public space, maintaining public order, and ensuring legal certainty. This study examines the implementation of billboard permit administration under Serang City Regional Regulation Number 3 of 2021. It applies an empirical juridical method with a qualitative approach. Data were collected through interviews with relevant local officials and a review of applicable laws and supporting legal materials. The findings indicate that the permit process involves several agencies: the Investment and One-Stop Integrated Service Office as the licensing authority, the Public Works and Spatial Planning Office for technical recommendations, the Regional Revenue Agency for tax collection, and the Municipal Police for supervision and enforcement. Although the regulatory framework is comprehensive, challenges remain, including inter-agency coordination, tax compliance, supervision effectiveness, and limited legal awareness among business actors. The study concludes that effective permit administration depends not only on clear regulations but also on strong institutional coordination and proper implementation.

Illegal street racing is a persistent issue in Indonesia, including Bungo Regency, endangering road users and violating traffic laws. This study, based on a case study at the Traffic Unit of Bungo Police Resort, aims to explore the police's role in addressing illegal street racing from an Islamic criminal law perspective. Using a qualitative juridical-empirical approach, the study examines legal regulations, institutional practices, and Islamic jurisprudence. Data was gathered from legal sources and literature related to law enforcement and Islamic criminal law. The results reveal that the police play a strategic role in combating street racing through preventative, preemptive, and repressive tactics. Repressive measures include law enforcement based on the Indonesian Traffic and Road Transportation Law, while preventive actions involve community outreach, traffic education, and regular patrols. From an Islamic criminal law viewpoint, illegal street racing is categorized as jarimah ta‘zīr, where authorities impose sanctions to maintain public order and prevent harm (mafsadah), aligning with the maqasid al-shariah goals of preserving property and life. The study concludes that effective and sustainable action against street racing requires collaboration between law enforcement, communities, and religious perspectives.

Domestic violence (DV) remains a complex legal and social problem, threatening family stability and human dignity. Although Law No. 23 of 2004 concerning the Elimination of Domestic Violence provides strict sanctions, conventional punishment methods are often considered ineffective in restoring damaged social relationships within families. This study examines the implementation of restorative justice in resolving domestic violence cases within the Bungo Police jurisdiction, from the perspective of positive law and Islamic law. This study uses an empirical legal approach and a sociological perspective, with primary data collected through interviews with investigators from the Women and Children Protection Unit (PPA), as well as secondary data from laws, police regulations, and related academic literature. The results show that restorative justice has been applied to several domestic violence cases during the investigation stage through mediation and peace agreements between the parties involved. This method helps reduce the backlog of cases, accelerates dispute resolution, and maintains family social stability. However, challenges remain, such as the possibility of re-victimization due to the imbalance of power between victims and perpetrators. From an Islamic legal perspective, restorative justice is in line with the principles of ta'zīr and maqāṣid al-sharī'ah, especially the preservation of human dignity, life and offspring. By guaranteeing the protection of victims and preventing repeated violence, restorative justice can be an additional mechanism in cases of domestic violence.

This study examines the effectiveness of the Jambi Regional Police in enforcing criminal law in the digital era, particularly in addressing online gambling offences, from the perspective of Islamic law. The rapid development of information technology has transformed crime from physical spaces into cyberspace, characterised by anonymity, speed, and transnational reach, thereby requiring adaptive law enforcement strategies. This research adopts a qualitative juridical-empirical approach. Data were collected through in-depth interviews with law enforcement officers at the Jambi Regional Police, analysis of case documents, and examination of relevant legal frameworks, particularly Indonesia’s Electronic Information and Transactions Law (ITE Law). The findings reveal that the Jambi Regional Police have implemented several strategic measures in combating digital crimes, including cyber patrols, digital forensic investigations, seizure of electronic evidence, and inter-agency coordination. Nevertheless, the effectiveness of law enforcement remains constrained by technological limitations, complex digital evidence requirements, the transnational nature of cybercrime, and limited public digital legal awareness. From an Islamic law perspective, police actions against online gambling align with the objectives of maqāṣid al-sharī‘ah, particularly the protection of religion (ḥifẓ al-dīn), property (ḥifẓ al-māl), and intellect (ḥifẓ al-‘aql). This study concludes that while digital criminal law enforcement by the Jambi Regional Police is fundamentally appropriate, it requires strengthened institutional capacity, integration of Islamic legal values, and adaptive policy reforms to enhance effectiveness and substantive justice.

This study aims to provide a comprehensive analysis of Predictive Policing and its implications for law enforcement transformation in Indonesia, based on an extensive review of its global applications, benefits, and challenges. The study uses qualitative literature and international case study review methods to assess the impact and complexity of implementing digital technologies such as artificial intelligence (AI), machine learning, and big data analytics within a Predictive Policing framework. The results of this review highlight that while Predictive Policing offers significant potential for proactive crime prevention and increased operational efficiency, its implementation is consistently fraught with critical legal, ethical, and technical challenges, including regulatory gaps, risks of algorithmic bias, and data privacy concerns, which are particularly relevant to Indonesia. The findings underscore that public trust and police legitimacy in the context of adopting such technologies are strongly influenced by transparency, strong accountability mechanisms, and community involvement in shaping their use. This study contributes to the growing discourse on digital policing in developing countries and culminates in practical policy recommendations designed to guide the Indonesian police towards the development and implementation of Predictive Policing models that are effective, efficient, and fundamentally respectful of legal and human rights principles.

Conflicts in transmigration areas are generally multidimensional and influenced by social, economic, land, and institutional factors. This study aims to identify the forms and distribution of conflicts in three districts of the transmigration area, namely Momi Waren District, Ransiki District, and Oransbari District, as well as to formulate a smart system-based conflict resolution approach through the use of spatial data, local institutions, and local wisdom-based settlement practices. Based on field mapping, four main categories of conflict were identified: 1) Land conflicts occur throughout the transmigration sites in the form of claims to transmigration land that has not been handed over to transmigrants because the compensation price is below normal. In addition, there is no ATR BPN office in South Manokwari Regency, one of whose functions is community empowerment and conflict resolution. 2) Economic conflicts occur because transmigrants are registered and recorded in the population registry, making it easy for them to access capital. Several economic activities in agriculture and transportation services are dominated by transmigrants, causing economic jealousy. 3) Social conflicts occur when the distribution of social assistance is uneven and the excessive use of illegally sold alcoholic beverages causes social unrest. 4) Institutional conflicts occur when civil servants, police, and military personnel are recruited, and not all indigenous Papuans who are nominated can be accommodated, requiring the involvement of tribal councils to formulate recommendations for recruitment that prioritize indigenous Papuans. The root causes of the conflict were analyzed using a root cause analysis approach that covered unclear land boundaries, unequal economic access, weak coordination between institutions, and low social trust due to differences in interests between groups. This study utilizes best practices from the Tribal Council, the South Manokwari Regency Transmigration and Manpower Office, the Religious Harmony Forum, and the Social Services Office as the basis for developing smart maps for an early warning system for conflicts. The results of the study formulate a Smart Conflict Resolution System framework consisting of three main components: (1) participatory spatial mapping of conflicts and key actors, (2) integration of institutional databases and social-customary mediation channels, and (3) design of smart maps as a mitigation and decision-making tool in transmigration areas. This system is expected to strengthen collaborative governance, prevent conflict escalation, and realize inclusive and sustainable management of transmigration areas

Quality public service represents a key measure of effective governance, including police administrative services. The Mobile Driving License (SIM Keliling) service is one of the public service innovations in the traffic sector designed to improve accessibility for the community. This study examines the quality of Mobile SIM services delivered by the Traffic Directorate of the East Java Regional Police at Lippo Plaza Sidoarjo. This research used a qualitative descriptive approach. Data collection techniques included observation, interviews with Mobile SIM officers and service users, and documentation. Service quality was analyzed using five dimensions proposed by Luke and Heyns (2020) reliability, responsiveness, assurance, empathy, and tangibles.The findings reveal that the Mobile SIM service generally performs well. Reliability is evident in the implementation of services in accordance with established procedures, although issues remain regarding service time certainty and transparency of administrative costs. Responsiveness is reflected in the officers’ prompt and attentive responses to public needs during the service process. Assurance is supported by officers’ professionalism, competence, and efforts to safeguard personal data, which enhance public trust. Empathy is demonstrated through friendly behavior, attention to individuals with special needs, and assistance throughout the service process. In terms of tangibles, the service location and main facilities are considered adequate; however, supporting facilities and officer identification still require improvement. In conclusion, while the Mobile SIM service fulfills most service quality indicators, further improvements are needed in time management, administrative transparency, and supporting facilities to achieve more optimal service quality.

This study evaluates the effectiveness of the SOSEK MALINDO (Malaysian-Indonesian Socio-Economic) regional collaboration program in addressing human trafficking, coordinated by the Regional Border Management Agency (BPPD) of the Riau Islands Province (Kepri). The Riau Islands Province, which borders Malaysia and Singapore, is a strategic entry point vulnerable to transnational crimes, including human trafficking. The main factors driving the people of Kepri to choose illegal routes to become Indonesian Migrant Workers (TKI) to Malaysia are economic pressure, limited job opportunities, attractive promises from brokers (tekong), complex and expensive official bureaucracy, and a lack of accurate information about official procedures. This situation is exploited by human trafficking networks through hidden routes, illegal ports, and methods of illegal labor and sexual exploitation. Although SOSEK MALINDO aims to improve the socio-economic welfare of communities in border areas and indirectly functions to reduce vulnerability to human trafficking, this program does not specifically make human trafficking its main focus. The BPPD plays a very important role as a liaison in cooperation with the Indonesian National Police, Immigration, and BP3MI for prevention and supervision. However, the BPPD faces challenges such as limited funding, overlapping authority between institutions, and a lack of accurate data on human trafficking. Strategic recommendations include making human trafficking a primary focus of the SOSEK MALINDO forum agenda, establishing a dedicated cross-border human trafficking task force, strengthening the BPPD's role in coordination and information gathering, and involving local communities, NGOs, and international organizations in mitigation efforts.

The public complaint system is an important facility for the police institution to improve the quality of public services, particularly in receiving, processing, and following up on various reports and complaints from the public. However, in practice, the complaint process is still largely carried out manually, such as through face-to-face interactions, paper-based forms, or direct communication that is not well documented. This gives rise to problems such as delays in handling, difficulties in tracking the history and status of reports, low work efficiency of officers, and limited transparency of information for reporters. These problems ultimately affect the level of public trust in the police institution. This study aims to design a web-based public complaint information system that supports a more structured, measurable, and transparent complaint management process. This system is designed by implementing the Kanban method as a workflow management tool that allows for prioritization, monitoring the handling process, and tracking the status of complaints in real time. The research methods include a literature review related to information systems and the Kanban method, direct observation of the existing complaint process, interviews with stakeholders, system requirements analysis, modeling using UML (Use Case Diagram, Activity Diagram, Sequence Diagram), and database design using Entity Relationship Diagram (ERD). The results of this research resulted in the design of a web-based public complaints information system that can facilitate complaint data recording, report management and status updates, task assignments to officers, performance monitoring, and complaint status notification to the public.

The handling of children involved in narcotics crimes requires a restorative approach focused on rehabilitation rather than punishment. This study aims to examine the role of police investigators in applying restorative justice to child offenders in narcotics cases and to identify the obstacles encountered in its implementation. This research employs a normative legal research method with statutory and conceptual approaches. Primary legal materials include Law Number 11 of 2012 on the Juvenile Criminal Justice System, Law Number 35 of 2009 on Narcotics, and Chief of Police Regulation Number 8 of 2021. The findings show that investigators play a strategic role in facilitating diversion, including conducting initial assessments, facilitating diversion deliberations, and coordinating with supporting institutions such as the Correctional Center (Bapas), National Narcotics Agency (BNN), and Social Services. However, implementation remains suboptimal due to internal constraints, including inadequate training and understanding among investigators, limited facilities such as child-friendly rooms and mediation spaces, regulatory disharmony between the Juvenile Criminal Justice System Law and the Narcotics Law, weak inter-agency coordination, and lack of support from families and communities. Post-diversion monitoring is also ineffective. This study concludes that strengthening investigator capacity through specialized training, improving legal frameworks through regulatory harmonization, and enhancing inter-agency collaboration are essential to ensure restorative justice truly serves the best interests of children.

This research examines the effectiveness of narcotics crime investigation by the Narcotics Investigation Unit (Satuan Reserse Narkoba) from the perspective of Indonesia's Criminal Procedure Code (KUHAP) and related legislation. The study also analyzes the juridical-normative obstacles encountered during investigation processes, along with potential solutions under Indonesian positive law. As an extraordinary crime, narcotics offenses require precise and legally sound investigation methods. However, investigative practices often face challenges due to inconsistencies between legal norms and field implementation, limited resources, and the absence of clear regulations on special investigative techniques such as wiretapping and controlled delivery. This normative legal research employs statutory and conceptual approaches, analyzing primary legal materials including Law Number 8 of 1981 (KUHAP), Law Number 35 of 2009 on Narcotics, and various implementing regulations. The findings indicate that narcotics investigations are not yet optimal due to weak technical regulations, disharmonized laws between KUHAP and the Narcotics Law, overlapping authority between the Police and the National Narcotics Agency (BNN), and a lack of protection for whistleblowers and witnesses. The legal gap in regulating special investigation methods creates uncertainty in evidence admissibility. Proposed solutions include regulatory reform through KUHAP revision, improving investigator competence through specialized training, utilizing modern technology, strengthening inter-agency coordination, and enhancing internal and external oversight mechanisms. Legal reform and institutional synergy are essential to enhancing the overall effectiveness of narcotics investigations in Indonesia.

This research aims to analyze the criminal liability of perpetrators of fraud through bounced checks and the legal protection provided to victims. The study focuses on Decision Number 1698/Pid.B/2022/PN Sby, in which the defendant was found guilty of fraud under Article 378 of the Indonesian Criminal Code (KUHP). Using a normative juridical approach through literature study with statutory and conceptual approaches, the findings demonstrate that the panel of judges correctly applied the elements of fraud, including malicious intent (mens rea), the use of deception or a series of lies, and actual loss suffered by the victim. The judge's legal considerations have reflected the principles of legality, justice, and legal certainty in criminal law. Legal protection for victims can be pursued through both criminal and civil legal remedies, where victims may report to police for criminal prosecution under Article 378 KUHP and claim compensation through civil breach of contract lawsuits. Law enforcement against perpetrators is carried out through repressive and preventive criminal sanctions. This decision confirms that bounced check fraud is not merely a civil breach of contract but can be classified as a criminal offense when accompanied by malicious intent to deceive others.

The aim of this research is to develop a new strategic model for Indonesian border defense by recalibrating the Lykke Framework. It assesses the relevance of the traditional ends–ways–means framework in addressing modern border threats and proposes adding a risk pillar to improve adaptability and multi-domain integration. Using a Systematic Literature Review (SLR), the study examines policy developments, defense doctrines, surveillance technologies, and geopolitical dynamics influencing Indonesian border security. Literature was sourced from international and national databases (ScienceDirect, SpringerLink, SINTA, BRIN, etc.) for publications between 2018–2025. The findings reveal that Indonesia's border regions face complex threats such as sovereignty violations, transnational crime, cyberattacks, and ideological penetration. These challenges highlight the inadequacy of the traditional ends–ways–means framework without incorporating a fourth risk pillar. The study introduces the New Lykke Model, which enhances the strategic framework for integrated military management, considering geopolitical, operational, socio-cultural, and environmental risks. This model offers practical guidance to stakeholders like the Indonesian National Armed Forces (TNI), Bakamla, and the National Police (Polri), aiming to improve border security operations and policy planning. The study is among the first to adapt the Lykke Model to Indonesian border defense, incorporating an integrated risk pillar for a more comprehensive security strategy.
