This study aims to analyze the performance of the mailing system information in an expedition company using the Unified Modeling Language (UML) approach. The mailing information system plays a crucial role in the smooth operation of the expedition company, particularly in managing the dispatch and delivery of letters and documents effectively and efficiently. This research uses a descriptive method with a quantitative approach to illustrate and analyze the extent to which the system's performance meets user needs. Data were collected through a questionnaire distributed to 25 respondents, consisting of 17 females and 8 males, to measure three key aspects of the system: user satisfaction, ease of use, and access speed. The results of the study show that the majority of respondents gave very positive assessments of the system. The easeof use aspect received the highest average score (4.4), followed by access speed (4.28) and satisfaction (4.24). However, there are areas that can still be improved, particularly regarding user satisfaction and system access speed for greater optimization. Overall, the study concludes that the mailing information system in the expedition companys functioning well, but the company needs to continue innovating and improving the system's performance to better meet user expectations.

Immigration is related to the traffic of people entering or leaving Indonesian territory and its supervision to maintain state sovereignty. Immigration functions include providing immigration services, law enforcement, and maintaining the security and comfort of the country, while contributing to the development of community welfare. With the increase in crimes involving fake identities or misuse of other people's identities, immigration must be stricter in checking travel documents used by Indonesian citizens and foreign nationals when entering and leaving Indonesian territory. Therefore, immigration introduced a new passport design and implemented the use of electronic passports. The research method used in this research is a descriptive qualitative method. The research results show that changes in passport design can increase state sovereignty and security, because the new design is difficult to imitate. This can be seen from the materials used in making the new passports as well as the designs that highlight elements of Indonesian culture. Applying for an electronic passport does require higher costs than a regular passport, but offers advantages that conventional passports do not have, including a better level of security. Using an electronic passport also makes it easier for the holder to undergo immigration service administration because this passport uses a biometric system that only needs to be scanned.

This study explores the political impacts of citizenship policy changes on Indonesia’s diplomatic relationships, particularly in the context of globalization and the movement of its diaspora. Indonesia currently maintains a single citizenship policy, preventing its citizens from holding dual nationality. This restriction often complicates the legal and emotional connections of Indonesians living abroad with their home country, while also limiting their economic contributions through remittances and investments. Conversely, many nations have adopted dual citizenship policies to maintain stronger connections with their diaspora and enhance their diplomatic influence. Using a qualitative approach with case studies focusing on countries with large Indonesian diasporas, such as Malaysia, Saudi Arabia, and the United States, this research highlights the potential benefits of dual citizenship. The findings indicate that allowing dual citizenship could strengthen Indonesia’s diplomatic ties and increase economic contributions from overseas Indonesians. However, there are challenges to implementation, including concerns over divided loyalty and complexities in legal enforcement. This paper suggests that Indonesia consider a carefully controlled introduction of dual citizenship, taking into account legal protections, economic benefits, and the role of the diaspora in promoting Indonesia’s interests abroad.

This study aims to analyze the quality of services at the Integrated Police Service Center (SPKT) of the Biak Numfor Police Department in improving public satisfaction. This research employs a qualitative narrative method with samples including the Head of SPKT of the Biak Numfor Police, police officers assigned to the SPKT, and community members who received SPKT services. The data collection instrument used was interviews. The findings indicate that the services provided by the Biak Numfor Police officers, particularly in terms of attitude, communication, and fairness, have been satisfactory. The friendly demeanor of the officers, such as smiling while receiving reports or complaints, leaves a positive impression on the community. However, certain aspects of the service remain below public expectations, including timeliness in following up on reports, clarity in case resolution, and officer discipline in service delivery. Additionally, there were some practices perceived by the community as lacking consistency, which affected the overall service quality. According to public surveys, these issues result in less-than-optimal satisfaction with the services at SPKT Biak Numfor Police.

This study aims to conduct a comparative analysis between national law and Islamic law, focusing on the principles, implementation, as well as the differences and similarities between the two in social, political, and cultural contexts. National law in Indonesia is a combination of customary law, colonial law, and modern law derived from Western legal systems, while Islamic law originates from Sharia, based on the Qur'an and Hadith. In certain areas, such as family law, civil law, and criminal law, these two legal systems exhibit distinct approaches, both philosophically and technically. The study finds that while national law emphasizes secularism and state sovereignty, Islamic law places greater emphasis on moral and divine justice. However, in the Indonesian context, both legal systems sometimes operate in parallel or undergo processes of adaptation and accommodation. This research contributes to a deeper understanding of the dynamics of the interaction between national law and Islamic law, as well as how both influence the judiciary and society in general.

This study examines the legal protection for stateless persons within the framework of citizenship and human rights. The focus is on assessing the effectiveness of international legal frameworks and national policies in safeguarding the fundamental rights of individuals without citizenship. The research employs a qualitative analysis of key legal instruments, including the 1954 Convention Relating to the Status of Stateless Persons and the 1961 Convention on the Reduction of Statelessness, alongside case studies of policy implementation across various countries. The findings reveal that, despite a robust international legal framework, there are significant gaps in implementation and enforcement, leading to ongoing discrimination and human rights violations against stateless persons. The study recommends comprehensive policy reforms and enhanced international cooperation to improve legal protection for this vulnerable group.

The role of Pancasila as a source of law within the adat (customary law) system in Indonesia involves analyzing its alignment and contemporary challenges. Pancasila, as the state ideology, serves as a fundamental guide for the formulation and application of laws throughout Indonesia. However, integrating Pancasila's values into the diverse adat legal systems presents significant challenges regarding both value alignment and practical application. This study uses qualitative analysis with a case study approach to evaluate how Pancasila’s principles are implemented in adat law and assess how well these values align with existing adat norms. Findings indicate that despite efforts to reconcile Pancasila with adat law, there are several obstacles, including differences in value interpretation, resistance from indigenous communities, and difficulties in harmonizing national and adat laws. The article concludes that a more dialogic and inclusive approach is needed to align Pancasila with adat law and recommends policy reforms and enhanced understanding of Pancasila's values at the local level to ensure fair and sustainable legal enforcement.

Rural and Urban Land and Building Tax is one of the main sources of State revenue for development financing. In the implementation of PBB-P2 collection, there are still many people who are not aware of the rights and obligations in paying taxes, this is due to the fact that there is still very low public awareness and knowledge in paying taxes. Public awareness as taxpayers in paying taxes will increase if there is an understanding of taxes in society. This research is an empirical legal research where data is obtained directly from the research location. Two types and sources of data are used, namely: primary data and secondary data. The data collection technique uses interview guidelines and literature/journal studies. The results of this study show that: (1). Taxpayer income in Fatululi Village is still very low in taxpayer awareness, economic conditions and the influence of Covid-19. (2). The government's countermeasures are still lacking in socialization or counseling to the taxpayer community. Suggestions need to be further increased socialization or counseling to the public about understanding paying PBB and need to be emphasized the existing tax sanctions.
