The purpose of this scientific paper is to design and implement a knowledge-based expert system to assist students in determining their major specializations at Vocational High Schools (SMK) more objectively and accurately. A major problem frequently faced by SMK students is the mismatch in department selection caused by a lack of understanding regarding their own potential and the specific criteria of each competency. To address this issue, the system was developed using the Forward Chaining method as the inference engine. This method operates in a data-driven manner, beginning with the collection of facts such as interests, academic abilities, and psychological aspects, which are then matched against a Knowledge Base consisting of IF-THEN logical rules. Based on system testing results, the inference engine is capable of processing the list of facts to generate a specialization diagnosis for SMK students and provide the most relevant departmental recommendations, such as Computer and Network Engineering (TKJ), Accounting, Office Automation and Governance (OTKP), or Marketing. The research results indicate that the implementation of the Forward Chaining method is effective in accelerating the decision-making process and minimizing placement errors. This expert system is expected to serve as a tool for Guidance and Counseling (BK) teachers in providing appropriate career direction for students based on structured empirical data.

The world of work is an environment related to the work we are currently in. In other words, it is a place where various individuals perform an activity. The quality of college graduates is not only seen in terms of high or good grades / GPA. There are many other considerations, where large companies see a potential possessed by the person concerned. The dataset in this study was taken from student respondents about the world of work. One way to classify the influence of competence on the world of work in machine learning is to use datasets as training data so that performance testing can be carried out with the right classification method. From the results of the tests carried out, it is concluded that the results of the comparison are different, which shows the accuracy value of KNN which is around 96%, while the results of the SVM accuracy tested are 98%, so that the accuracy of SVM is better than KNN.

The Planning, Research, and Development Agency (BAPPELITBANG) has an important role in supporting regional development planning and evaluation. One of the main activities of this agency is the coordination of working visits with external agencies or institutions. The process of managing schedules and work visit reports is currently still carried out manually, causing obstacles such as delays in information, duplicate schedules, and lack of integration of report data. This research aims to design a web-based application that is able to manage work visit schedules in a structured manner and facilitate the creation of visit reports digitally. The method used in this study is the Waterfall system development method which includes needs analysis, system design, implementation, and testing. The results of the study show that the application is able to display the visit schedule in real time, minimize schedule conflicts, and speed up the process of preparing work visit reports. Thus, this application makes a significant contribution in increasing the effectiveness and efficiency of the work visit administration process at BAPPELITBANG.

Toddlers are a vulnerable age group to various types of diseases due to their immune systems that are still developing. Limited utilization of medical record data and the lack of structured information regarding disease patterns in toddlers based on age and causative factors have resulted in suboptimal prevention and treatment efforts. Therefore, an approach is needed to systematically classify toddler disease data. This study aims to apply data mining techniques using the clustering method with the K-Means algorithm to group types of diseases in toddlers based on age and causative factors. The variables used in this study include toddler age, type of disease, and causative factors. The data were obtained from RSUD Dr. R. M. Djoelham Binjai and processed using MATLAB software with three clusters. The results show that the K-Means algorithm successfully groups toddler disease data into three clusters with different characteristics. The first cluster is dominated by toddlers aged 0–11 months with appendicitis caused by genetic factors. The second cluster is dominated by toddlers aged 1–3 years with diarrhea caused by environmental factors and has the largest number of members. Meanwhile, the third cluster is dominated by toddlers aged 0–11 months with sore throat caused by environmental factors. The clustering results indicate a relationship between toddler age, disease type, and causative factors, which can be used as supporting information for decision-making in the prevention and treatment of toddler diseases.

The rapid development of artificial intelligence has encouraged the widespread use of chatbots on social media platforms, transforming patterns of digital communication and interaction. This study aims to examine the role of chatbots in shaping social interaction, fandom dynamics, and users’ digital identities within contemporary online culture. The research employs a literature review approach using grounded theory as an analytical framework to identify patterns, themes, and emerging concepts from relevant academic publications published between 2021 and 2025. Articles were collected through academic databases and systematically selected based on predefined inclusion and exclusion criteria. The findings indicate that chatbots have shifted from being purely functional technological tools to becoming cultural actors that influence emotional engagement, community formation, and identity expression in digital spaces. Chatbots contribute to creating perceived emotional closeness, strengthening fandom interactions, and facilitating self-expression, particularly within popular culture and creative industries. However, the study also highlights several challenges, including emotional dependency, algorithm-driven homogenization of preferences, gender bias, and aggressive behavior in human–machine interactions. Cultural context plays a significant role in shaping user acceptance and interpretation of chatbots. These findings imply that chatbot development and implementation should consider not only technical efficiency but also social, psychological, and ethical dimensions to ensure responsible and inclusive digital interaction.

Through this study, the research team aims to assess the capacity of the Puloniti village government to carry out digital work transformation and identify the main obstacles that hinder it. This research was conducted using a qualitative descriptive approach through observation, interviews, and documentation. This study identified two main obstacles for the Puloniti village government in carrying out digital performance transformation: limited human resource literacy and inadequate software facilities and infrastructure.

Development in Banten Province has created conflict in development due to the dominance of a minimalist modern science approach, which prioritizes economic growth while ignoring environmental carrying capacity and socio-cultural values. As a result, Banten faces a serious environmental crisis, as evidenced by high emissions of air pollutants (PM2.5, SO2) and river water pollution by industrial waste. This study aims to analyze the negative impacts of this disorganized model and propose a comprehensive solution framework. This study formulates the Holistic Development Model (HDM). The HDM is a transformative solution that synergistically integrates three pillars: Modern Science (providing technology and data), the Ecosystem Approach (providing a systemic framework and nature-based solutions), and Local Cultural Values ​​(forming the basis of ethics and social motivation) through a Systematic Literature Review and Conceptual-Case Analysis. The implementation of MPH in case studies such as Integrated Coastal Management and Integrated Agriculture demonstrates that this integration produces high-yielding, equitable, and sustainable systems. In conclusion, MPH is a crucial strategy for Banten to shift from destructive development to equitable, resilient, and locally rooted development, making ecosystem health a key measure of success.

This study aims to understand and analyze the long journey of Banten Province, from its formation process to the political and governmental developments that have taken place within it. We used a historical-analytical qualitative approach with the aim of providing an in-depth analysis of the long journey of Banten Province. The issues studied range from the formation process of Banten to the political and governmental developments that have taken place within it. The results of our research show that the formation of Banten Province as part of decentralization and regional autonomy has not been entirely successful in eliminating the dominance of political dynasties. This practice limits the space for community participation and strengthens political oligarchy, so efforts need to be made to increase and provide community participation in the political dynamics in Banten and strengthen local democracy. This study suggests that efforts are needed to increase community participation, strengthen local democracy, and overcome political dynasties in order to improve the welfare of the people of Banten.

Marriage is principally intended to establish a happy and enduring family. However, in practice at Puncak area of Bogor Regency has seen the growth of contract marriage, a practice that often resembles disguised prostitution and may facilitate the exploitation of women. This research aims to analyze the legal position and validity of contract marriage from the perspectives of islamic law and Indonesian positive law, as well as to explain its legal consequences for women and children. This study employs a normative juridical method through an examination of positive law, legal doctrine, and prior research, and applies both a statute approach and a case approach. The findings indicate that contract marriage is a time limited marriage that contradicts the objective of marital permanence under the Marriage Law. In Islamic law, the practice is equated with mut’ah marriage, which is prohibited, and if conducted it is deemed void by operation of law. Under Indonesian positive law, contract marriage is not recognized, and its agreement does not satisfy the legal requirements for a valid contract under Article 1320 of the Civil Code. As a result, women may lose civil rights such as maintenance, inheritance rights, and entitlements to joint marital property, while Out-of-Marriage Children may have a limited civil relationship only with the mother and the mother’s family. Therefore, contract marriage lacks validity under both Islamic law and Indonesian positive law and may generate legal, social, and moral harms, particularly for women and children.

Marriage agreements frequently give rise to juridical issues when intersecting with inheritance law, particularly within the context of second marriages. This study is based on an inheritance dispute examined in the Palangka Raya District Court Decision Number 21/Pdt.G/2022/PN.Plk, wherein the second wife argued the existence of a marriage agreement to annul the inheritance rights of children from the previous marriage. Using a normative juridical method with statutory and case approaches, this research evaluates the agreement’s validity against formal registration requirements and freedom of contract limitations. The findings indicate that the marriage agreement invoked by the defendant was declared invalid and lacked binding legal force due to noncompliance with the formal registration requirements under Article 29 of the Marriage Law and the inclusion of clauses contrary to inheritance provisions in the Civil Code, particularly concerning the rights of children as lawful heirs. Consequently, the disputed property was classified as marital property to be distributed among all heirs in accordance with applicable law. This study affirms that freedom of contract in marriage agreements is limited and cannot override legal protection of legitimate heirs.

This research discusses the effectiveness of the implementation of diversion for children in conflict with the law in the crime of aggravated theft, with a case study at the Surabaya Children Crisis Center (SCCC). The background of the research is based on the importance of protecting children's rights in the criminal justice sistem, in accordance with Law Number 11 of 2012 concerning the Child Criminal Justice Sistem (UU SPPA), which prioritizes restorative justice and the principle of diversion to avoid the negative impact of formal punishment on children. This research uses empirical juridical method with descriptive analysis approach, examining primary data from interviews with legal counsel at SCCC as well as secondary data from related legal literature. The results show that diversion at SCCC has been implemented according to procedures at various stages of the legal process, from investigation, investigation, to trial. However, the implementation still faces obstacles such as the lack of understanding of law enforcement officials, limited human resources at legal aid institutions, and challenges in mediation between offenders and victims. In conclusion, although the implementation of diversion in SCCC is quite effective in protecting children's rights and preventing social stigma, the implementation of diversion in SCCC is not yet effective.

Marriage is the only way to legalize the relationship between men and women in order to realize the happiness of family life. Marriage is also a complement to the religion of Muslims. However, because marriage basically unites two different individuals, it certainly does not rule out the possibility of differences of opinion and other problems. Divorce is the last resort for a marital relationship that can no longer be maintained, divorce can occur for several reasons, including because the couple has changed religions, as contained in the Compilation of Islamic Law Article 116 letter H. Divorce certainly causes a legal consequence, one of which is the effect on children. If the divorce occurs because the wife or a mother has changed, then how is the determination of custody of a child who has not been mumayyiz. The purpose of this study is to find out the judge's considerations in determining child custody due to divorce because the couple changed religion in the decision Number 1515/Pdt.G/2015/PA.Smn. This research is a normative-empirical legal research, this research data uses secondary data consisting of primary, secondary and tertiary legal materials. To complete the secondary data, interviews were also conducted with the judge at the Sleman Religious Court. Based on the results of the research and analysis that has been carried out, it can be concluded that the judge's consideration in deciding the case of determining child custody due to divorce caused by a couple converting (apostasy) at the Sleman Religious Court was given to the Applicant as his father in order to maintain the safety of his child's faith and the best interests for his child and for the sake of the child's future.

This study analyzes the role of the Golkar Party of Serang City in the formulation and oversight of Regional Regulation Number 11 of 2019 on the Implementation of Tourism Business Governance using the Institutional Analysis and Development (IAD) framework. The study aims to examine how political party institutions perform their functions in local legislative processes, particularly in terms of public representation, interest articulation, and policy oversight. A qualitative case study approach was employed, involving in-depth interviews with party actors and members of the Regional House of Representatives (DPRD), as well as document analysis of relevant policy materials. The findings reveal that Golkar’s role in the formulation and supervision of the regulation was predominantly carried out by its legislative faction through informal mechanisms, while the party’s organizational structure played a limited institutional role. The process of absorbing public aspirations was relatively constrained and tended to favor groups with close social and political ties, indicating that the party has not fully exercised its functions of public articulation and accountability. From the perspective of the IAD framework, this condition reflects weaknesses in internal rules, actor capacity, and interaction mechanisms within the party as a political institution in the policy arena. Therefore, strengthening Golkar’s institutional capacity is essential to enable a more substantive, responsive, and inclusive role in local legislative and policy oversight processes

This study examines the application of restorative justice in traffic accidents during the investigation stage. The main focus of this research is to analyze the regulations and implementation process. The goal is to comprehensively describe how restorative justice policies are regulated by law and how they are practiced in the field, particularly by investigators. The research method used is a juridical- normative method with a qualitative approach. Data were obtained through literature review and in-depth interviews with relevant parties. The results indicate that restorative justice can be applied in resolving traffic accident cases, especially those resulting in minor losses or minor injuries. This regulation is contained in various regulations, such as Police Regulations and Circular Letters that serve as guidelines for investigators. The implementation process involves mediation between the perpetrator, the victim, and other relevant parties to reach a peaceful agreement. This agreement often includes compensation, an apology, or other mutually agreed-upon forms of reparation. The application of restorative justice aims to restore conditions to normal, restore social relationships, and avoid lengthy formal judicial processes. However, its implementation still faces challenges, such as unequal public legal awareness and the criteria for cases that can be resolved through restorative justice.

This study discusses the status of marriage books as legal and administrative documents, as well as the mechanism for their disposal as State-Owned Goods (BMN) at the Regional Office of the Ministry of Religious Affairs in Papua Province. The marriage book serves as valid evidence of marriage and plays an important role in population data management. As a document printed using the state budget (APBN), the marriage book is classified as BMN, and its management must comply with regulations. A qualitative approach with an empirical juridical method is used to examine the relationship between legal regulations and their implementation practices. Data were collected through interviews, observations, and literature studies with officials from the Islamic Guidance Division of the Ministry of Religious Affairs in Papua. The results indicate that the disposal of marriage books follows the Directorate General of Islamic Guidance Circular Letter No. 5 of 2024 and Ministry of Finance Regulation No. 83/PMK.06/2016. The disposal process is carried out in stages through administrative and physical mechanisms with principles of accountability and transparency. However, in Papua, the process of collecting unused marriage books has not yet reached the physical disposal stage. The disposal of marriage books is a strategic step in realizing good governance.

This study aims to determine and analyze the comparison of authority and characteristics between the Nusantara Capital Authority and the Labuan Bajo Authority in the administration of the Indonesian government. The type of research used in the research on the comparison of the authority of the Nusantara Capital Authority Authority and the Labuan Bajo Authority in the Implementation of Indonesian Government is still the same as the initial research proposal, namely using the type of normative law research (normative law research) which is carried out by examining library materials or secondary data. Comparison of the authority between the Nusantara Capital Authority and the Labuan Bajo Authority, namely the authority of the Nusantara Capital Authority (IKN) is regulated in Law Number 3 of 2022 concerning the National Capital and further regulated through Government Regulation Number 27 of 2023 concerning the Special Authority of the Nusantara Capital, namely special authority related to granting investment licenses, ease of doing business, and providing special facilities to parties that support the implementation of the Indonesian Government, as well as the provision of special facilities to parties that support financing in the context of preparation, construction, and relocation of the National Capital, as well as the development of the Archipelago Capital and partner regions and authority in government affairs, while the authority of the Labuan Bajo Authority Agency

The increasingly massive development of social media has been exploited by terrorist groups as a strategic tool to spread propaganda, violent ideology, and radicalism to the wider community, especially the younger generation. This situation demands an effective counter-radicalization strategy that adapts to the dynamics of the digital space. This study aims to analyze the strengthening of legal instruments and the role and institutional structure of the National Counterterrorism Agency (BNPT) in implementing social media-based counter-radicalization policies. The research method used is a normative juridical approach with a legislative approach and a conceptual approach, through a review of laws and regulations, legal doctrine, and policies related to counter-terrorism in Indonesia. The results show that the normative legal basis for BNPT's authority to carry out counter-radicalization is already available, particularly in the Law on the Eradication of Criminal Acts of Terrorism. However, its implementation still faces various obstacles, including weak derivative regulations specifically governing the supervision and counter-measures of digital radicalism, limited inter-agency coordination, and suboptimal evaluation of data- and technology-based policies. Therefore, this study recommends strengthening derivative regulations, increasing the digital capacity of BNPT, and developing a more integrated coordination and evaluation system.

Communal land in Kenagarian Tarantang has undergone conversion into tourism areas, bringing impacts on local environmental conditions. This study aims to explain the forms of communal land conversion into tourist areas, environmental conditions after conversion, and its impact on the environment in Kenagarian Tarantang. The research employed a quantitative associative approach involving 50 respondents randomly selected from 789 households. Data were collected through questionnaires, field observations, and interviews, then analyzed using simple regression analysis. The results showed that communal land conversion occurred intensively for homestay construction and tourism facilities with a total score of 1121 in the good category. Environmental conditions were generally well-controlled with a score of 983 in the very good category, although there were impacts such as reduced vegetation and decreased water quality. Regression analysis confirmed a significant influence between communal land conversion and environmental conditions at 18.49 percent with a significance value of 0.002. Community participation in maintaining the cleanliness of tourism areas was very good, however, stricter government supervision, reforestation programs, and adequate waste management are needed to prevent ecosystem degradation in the future.

The digital era has significantly transformed the way Indonesian society communicates, accesses information, and builds social interactions. These rapid changes have created new challenges for strengthening the values of Pancasila, especially as digital platforms increasingly become spaces where misinformation, hate speech, intolerance, and extreme polarization emerge. This study examines the relevance of Pancasila in guiding ethical behavior within the digital environment and highlights the strategic role of young people as key actors in maintaining national identity and moral integrity. Using a descriptive qualitative approach and literature analysis, the study finds that Pancasila remains highly relevant in addressing technological, social, and cultural disruptions. The values of divinity, humanity, unity, democracy, and social justice are essential for promoting responsible digital citizenship, fostering tolerance, encouraging critical thinking, and strengthening social cohesion. The study concludes that strengthening Pancasila-based digital ethics requires collaboration among the government, educational institutions, digital platforms, and society to ensure that digital transformation aligns with national moral foundations.

In Indonesia in 2020, there were 28,158 infant deaths, of which 20,266 (72%) occurred during the neonatal period. Among these neonatal deaths, 27.4% were caused by neonatal asphyxia. In West Kalimantan Province, there were 682 neonatal deaths recorded in 2023. The leading causes of neonatal mortality in 2023 were Low Birth Weight (LBW) and prematurity (32%), followed by asphyxia (24%). Based on the 2023 Sintang Regency health profile, the infant mortality rate was 9.6 per 1,000 live births. This study aimed to determine the relationship between LBW and the incidence of neonatal asphyxia. The research used an analytical observational approach with a cross-sectional design. The study was conducted at Ade M. Djoen Sintang Regional Hospital from January to December 2023 using secondary data. The population consisted of all newborns at Ade M. Djoen Sintang Regional Hospital, totaling 104 infants. A total sampling technique was applied, resulting in a sample size of 104 respondents. Data were analyzed using the Chi-square test. The Chi-square analysis produced a p-value of 0.0241 (p < 0.05), indicating a statistically significant relationship between Low Birth Weight (LBW) and neonatal asphyxia. The Odds Ratio (OR) of 4.021 shows that LBW infants have a 4.021-fold higher risk of experiencing neonatal asphyxia compared to infants with normal birth weight.
