This study aims to analyze the relationship between self-control and the moral development of students at Medan State University. Self-control is an individual's ability to control emotions, impulses, and behavior to align with prevailing moral norms and values ​​in both academic and social settings. This study employed quantitative methods, collecting data through questionnaires distributed to students. The research instrument was used to measure students' levels of self-control and their moral development, as reflected in their attitudes of responsibility, honesty, discipline, and ethical behavior on campus. The data obtained were analyzed to determine the relationship between the two variables. The results showed that students' levels of self-control were considered good and had a positive relationship with moral development. This suggests that students with better self-control tend to display behaviors consistent with prevailing moral values ​​and norms. Therefore, self-control plays a crucial role in the moral development of students, necessitating ongoing efforts by universities to support the development of self-control through character development and academic activities oriented toward moral values.

The moral crisis in contemporary education demands a reconstruction of moral values derived from the Qur'an as the epistemological foundation of Islamic education. This study aims to identify and analyze the moral educational values found in Surah Al-Imran, verse 159, particularly through the perspectives of Ibn Kathir’s tafsir and Quraish Shihab’s Tafsir Al-Misbah, and formulate its implications for contemporary Islamic education practices. Using a qualitative approach with a library research method, this study analyzes primary data from Ibn Kathir’s tafsir and Tafsir Al-Misbah, confronted with secondary literature on moral education theory. The analysis technique used was content analysis with a comparative-analytical approach to extract both explicit and implicit moral educational values. The findings revealed three fundamental values: first, gentleness (ar-rifq) as a humanistic pedagogical communication method; second, forgiveness (al-‘afw) as a mechanism for restoring educational relationships; third, consultation (asy-syura) as a democratic principle in educational decision-making. This study concludes that these values are not merely individual ethics but methodological principles that must be integrated into the culture of Islamic educational institutions. Practically, this requires a transformation from authoritarian-monological to dialogical-participatory educational approaches and strengthening educators' socio-emotional competencies.

This study aims to analyze the novel Laskar Pelangi by Andrea Hirata using a critical hermeneutic approach developed by Jürgen Habermas. The focus of this research is to uncover the critical meaning contained in the novel as a reflection of social reality, especially in the field of education. The method used is descriptive qualitative research with data collection techniques through literature studies and text analysis in the form of excerpts in novels. The results of the study show that the novel Laskar Pelangi not only presents an inspiring story, but also contains criticism of the education system in Indonesia which is still colored by inequality and injustice. In the aspect of communicative action, it was found that there was a dialogical interaction between teachers and students as well as the value of solidarity and strong struggle. However, in the aspect of communication distortion, there is injustice in access to education and a lack of space for poor groups to voice their interests. In addition, the analysis also reveals the existence of ideology and domination, especially economic dominance over education and social systems that oppress the lower groups. On the other hand, the emancipatory interest in this novel is reflected through education as a tool of liberation and the struggle of its characters in fighting against limitations. Thus, this study concludes that the novel Laskar Pelangi has an important role as a social criticism medium that is able to build readers' critical awareness of the reality of education and social inequality that occurs in society.

This study aims to analyze the short story “Siapakah Keluarga dari Tubuh yang Kacau Itu?” by Radja Sinaga using structural and moral approaches in order to obtain a comprehensive understanding of its content and meaning. The structural approach is employed to examine intrinsic elements, including theme, characters and characterization, plot, setting, point of view, language style, and message. Meanwhile, the moral approach is used to reveal the ethical values and life lessons contained in the short story. This study applies a descriptive qualitative method, with data collected through library research by means of intensive reading and systematic note-taking of the text. The results show that the short story demonstrates a strong structural unity, with the main theme focusing on human suffering caused by war and the loss of family. In addition, several moral values are identified, such as humanity, familial love, criticism of violence, loss of identity, and resilience in facing suffering. The use of the second-person point of view also strengthens the reader’s emotional engagement with the story. Therefore, the combination of structural and moral approaches provides a deeper understanding of the meaning of the short story and its relevance to real-life contexts. This study is expected to enrich literary studies and enhance readers’ appreciation of literary works.

This study analyzes the news text on the online mass media detik.com titled "Jule's Infidelity Issue, Na Daehoon: I am strong for the sake of the children" using Sara Mills' Critical Discourse Analysis model. This research aims to reveal how the discourse of infidelity is constructed in media texts thru subject and object positioning, how character representation is displayed, how the reader's position is directed, the use of narrative structure, and the social context and gender ideology underlying the construction of this discourse. The research method used is a qualitative descriptive method with the data source being a news text published on detik.com. Data collection techniques were carried out thru document study by carefully reading and recording linguistic units relevant to the research focus, while data analysis techniques used Sara Mills' Critical Discourse Analysis model. The research findings indicate that Na Daehoon is positioned as the dominant subject, possesses voice legitimacy, and is positively represented as a strong and responsible male figure. Conversely, Jule is positioned as the object of news coverage, receiving no opportunity for clarification and being implicitly represented as the problematic party. Additionally, the narrative structure and language choices used in the news text also guide readers to build sympathy toward the male subject. The findings indicate that the analyzed news coverage is not neutral, but rather tends to reproduce patriarchal gender ideologies that could potentially influence society's perception of women in cases of infidelity.

The dominance of digital technology in contemporary society has led to a shift in human values. Technology no longer serves merely as a tool but has evolved into a crucial system shaping interaction, communication, and behavior. This study uses qualitative methods to examine how digital technology influences human values in modern society. For this purpose, a literature review was carried out, incorporating thematic analysis of relevant sources. According to this study, the prevalence of digital technology has significantly transformed many aspects of social life. This includes the transition from a user-centered paradigm to a more automated system-centered paradigm; the conversion of human identity into data representation in digital systems; as well as the move from in-person to online communication within social exchanges. These effects undermine the quality of social relationships, reduce empathy and interpersonal interaction, increase dependence on technology, and lead to dehumanization. Furthermore, changes in information perception have the potential to improve digital literacy but simultaneously reduce the quality of critical public reflection. Nevertheless, digital technology continues to offer advantages such as easier access to information and productivity gains. Therefore, strategic efforts are needed to improve user-centered technology, digital skills, and adaptable regulations.

The right to privacy and the right to health are fundamental human rights that are closely interconnected. The protection of privacy for patients with Human Immunodeficiency Virus (HIV) constitutes a critical issue, given that HIV status is classified as highly sensitive health data and is particularly vulnerable to stigma and discrimination. In Indonesia, the legal framework governing the protection of HIV patients’ health data has been normatively strengthened through the Personal Data Protection Law and the Health Law; however, its implementation continues to face various challenges. This article aims to analyze the right to privacy of HIV patients and the obligations of the state in protecting sensitive health data, as well as to examine the limitations and exceptions to the disclosure of HIV-related data within the framework of law and human rights. This study employs a normative legal research method using statutory, conceptual, and human rights-based approaches. Legal materials are analyzed qualitatively through juridical interpretation and prescriptive analysis. The findings indicate that HIV status is legally categorized as sensitive personal data that is entitled to a high level of legal protection. The state bears tripartite obligations to respect, protect, and fulfill the privacy rights of HIV patients. Nevertheless, a gap persists between legal norms and their implementation, particularly in the management of electronic medical records. The protection of HIV patients’ privacy rights requires strengthened legal implementation, regulatory harmonization, and the adoption of a human rights-based approach to ensure that data protection does not conflict with public health interests.

This study aims to analyze the phenomenon of slang usage on the TikTok social media platform as a form of linguistic adaptation in digital communication. Using a qualitative descriptive approach, this research examines how users modify language structures to create more effective, expressive, and socially meaningful interactions. Data were collected through participatory observation of content appearing on the For Your Page (FYP) feature and analyzed using textual and contextual methods. The findings reveal that slang formation on TikTok occurs within three main domains: phonological transformation through sound reduction to produce linguistic aesthetics, morphological modification through the creation of efficient acronyms, and cognitive-semantic shifts that redefine the meanings of existing vocabulary. These findings demonstrate that slang is not merely a temporary communication trend, but also functions as an important sociolinguistic instrument for constructing group identity, strengthening emotional connections, and reflecting the cognitive and cultural dynamics of contemporary digital society amid the rapid development of information technology.

The president's prerogative is a form of power inherent in the president's position as head of state. One form of this prerogative is the granting of abolition, which is the abolition of legal proceedings against a person or group of people who are or will undergo judicial proceedings. However, in its implementation, the president's authority to grant abolition is not absolute, but is limited by the applicable legal provisions and constitutional mechanisms. This study aims to analyze the limits of the president's power in exercising the prerogative in the form of abolition and review the juridical aspects that govern the procedure and its considerations. The research method used is normative juridical research with a statutory approach and a conceptual approach. Data sources are obtained from relevant laws and regulations, legal literature, and scientific works. The results of the study show that the president's authority in granting abolition is regulated in Article 14 paragraph (2) of the 1945 Constitution of the Republic of Indonesia, which requires the president to pay attention to the considerations of the House of Representatives (DPR). Thus, this authority is not an absolute prerogative, but is limited by the principle of checks and balances in the Indonesian constitutional system. The conclusion of this study emphasizes that the restriction is a form of constitutional supervision over the use of presidential power to remain in line with the principles of the rule of law and constitutional democracy

Illegal logging is a serious environmental problem in Indonesia due to its direct impact on forest destruction, biodiversity loss, and increased carbon emissions. The Indonesian government has established various public policies and legal instruments to address illegal logging practices, such as the Forestry Law, the licensing system, and strengthening law enforcement agencies. However, the effectiveness of these policies remains a concern, given that illegal logging cases continue to occur in various regions. This study aims to assess the effectiveness of public policies in enforcing environmental law, focusing on illegal logging cases in Indonesia. The method used in this study is a normative juridical approach by examining regulations, government policies, and secondary data from reports from relevant institutions and previous research results. Analysis shows that despite comprehensive public policy design, its implementation still faces various obstacles, such as weak oversight, poor coordination between institutions, limited human resources, and corrupt practices. Furthermore, social and economic factors in communities surrounding forests also influence the success of environmental law enforcement. Therefore, strengthening law enforcement agencies, transparency and accountability, and active community involvement in forest management are essential. With these improvements, public policy is expected to be more effective in preventing and combating illegal logging for the sake of environmental sustainability in Indonesia.

The determination of a minimum marriage age is a central issue in Indonesian family law and Islamic legal discourse, particularly regarding the prevention of health, social, and psychological risks associated with child marriage. This study analyzes the alignment between the legal requirement of a minimum age of 19, as stipulated in Law No. 16 of 2019 and Constitutional Court Decision No. 22/PUU-XV/2017, and the framework of maqāṣid sharī‘ah, especially the hierarchical structure of dharuriyyāt, ḥājiyyāt, and taḥsīniyyāt. Employing a normative juridical method supported by extensive literature review, this research examines statutory regulations, classical and contemporary Islamic legal sources, works on maqāṣid, and empirical data from national and international institutions. The findings demonstrate that the minimum age of 19 substantively accords with maqāṣid sharī‘ah: at the dharuriyyāt level, it safeguards life, intellect, and lineage from medical, psychological, and social harm; at the ḥājiyyāt level, it prevents economic hardship, emotional instability, and the inability of young couples to assume household roles; and at the taḥsīniyyāt level, it preserves human dignity, ethical conduct, and the sanctity of marriage. Consequently, the regulation is not a departure from classical Islamic jurisprudence but rather an implementation of public interest (maṣlaḥah) adapted to contemporary societal realities. This study affirms that integrating maqasid-based reasoning into public policy strengthens the protection of families and future generations in Indonesia.

This study aims to analyze the contribution of Regional Original Revenue (PAD) sources, the growth of PAD, and the level of regional fiscal independence in Tanjung Jabung Barat Regency during the 2017–2024 period. The PAD sources examined include local taxes, regional retributions, returns from separated regional assets, and other legitimate PAD. The data used in this study are secondary data in the form of Budget Realization Reports (LRA) of Tanjung Jabung Barat Regency for the period 2017–2024, obtained from the Regional Revenue Agency (Bapenda) of Tanjung Jabung Barat and the Directorate General of Fiscal Balance. This research employs a quantitative descriptive approach. The analytical techniques used include contribution analysis of PAD sources (local taxes, regional retributions, returns from separated regional assets, and other legitimate PAD), PAD growth analysis, and fiscal independence ratio analysis. The results indicate that PAD is predominantly contributed by other legitimate PAD, accounting for 62.54% of total PAD, followed by local taxes contributing 26.06%, while regional retributions and returns from separated regional assets contribute relatively low proportions. The growth of PAD during the study period shows fluctuations influenced by economic conditions, including the impact of the COVID-19 pandemic. Furthermore, the level of fiscal independence in Tanjung Jabung Barat Regency is categorized as very low, as reflected in the high dependence on transfer funds from the central government and other governmental assistance.

This study aims to analyze the strategies of multicultural Islamic Religious Education (PAI) learning in fostering students’ tolerance attitudes in the context of Indonesia’s diverse society. This research employs a qualitative approach using a library research method by examining various relevant scientific literatures, including journals, books, and policy documents. Data were analyzed through stages of data collection, reduction, thematic analysis, and synthesis. The findings indicate that there are three main strategies in implementing multicultural-based PAI learning: (1) enrichment of teaching materials with multicultural perspectives, (2) application of dialogic discussion and cooperative learning methods, and (3) creation of a democratic and inclusive school culture. These strategies are proven to significantly contribute to the development of students’ tolerance, inclusivity, and respect for diversity. However, several challenges are identified, such as limited teacher competence, lack of inclusive teaching materials, social pressures, and the influence of digital media. In conclusion, multicultural-based PAI learning plays a crucial role in shaping tolerant and inclusive students. Its successful implementation requires a holistic, adaptive, and collaborative approach involving curriculum development, teacher competence enhancement, and support from the broader educational ecosystem.

This research is motivated by the importance tank cleaning process on tankers to prevent cargo contamination, maintain cargo quality, and ensure crew safety. MT. Marina Prosperity, a chemical/oil tanker, uses the Butterworth system as the primary method for tank cleaning at every cargo change. However, in practice, technical and operational constraints are still found that affect the results of tank cleaning. The research method used is descriptive qualitative with data collection techniques through direct observation on the ship, interviews with the Chief Officer and Boatswain, and documentation studies in the form of log books and SOPs. Data were analyzed by focusing on three aspects, namely work efficiency, work safety, and operational procedures for using Butterworth. The results show that the use of Butterworth can increase time and energy efficiency compared to manual methods, with an average cleaning time of 2–4 hours per tank depending on the type of cargo. From a safety aspect, Butterworth reduces the need for crew to enter the tank, thereby reducing the risk of exposure to chemicals and hazardous atmospheres. However, work effectiveness and safety are greatly influenced by the condition of the equipment, the stability of water pressure, and the crew's discipline in implementing the SOP. On several occasions, steps such as nozzle cleaning, manual mopping, and safety meetings were not consistently performed, resulting in residual load in certain areas. With routine equipment maintenance, close supervision, and ongoing crew training, Butterworth can be optimized to produce more effective, safe, and standards-compliant tank cleaning process.

Population growth and socio-economic activities increase traffic volume, affecting the performance of the Raden Kusno – A. Djaelani – Sujarwo signalized intersection. This study aims to analyze the intersection’s current performance, estimate its condition over the next five years, and formulate alternative treatment strategies. The research data include geometric characteristics, signal timing, vehicle speed, and traffic volume obtained from CCTV recording over a three-day observation period from moning to evening, as well as population and vehicle data for projection. The intersection performance was analyzed using the PKJI 2023 approach and VISSIM simulation. Under current conditions, the intersection operates at LOS E with delays of 45,12 seconds (PKJI 2023) dan 60,56 seconds (VISSIM). In the five-year projection, delays increase to 48,97 seconds with LOS E (PKJI 2023) and 131,29 seconds with LOS F (VISSIM). Modifying the signal from four to three phases with a 70-second cycle improves the current condition to LOS C, with delays of 24,50 seconds (PKJI 2023) and 29,43 seconds (VISSIM). For the five-year projection, adding a continuous left-turn lane results in LOS D with 27,04 seconds (PKJI 2023) and LOS C with 32,01 seconds (VISSIM).
