Adolescence is an important period in the formation of a person's personality, where individuals tend to be easily influenced by the social environment including associations. Unhealthy associations have the potential to cause various problems such as peer pressure, low self-confidence, and the emergence of deviant behavior. This service activity aims to increase the awareness and understanding of Muhammadiyah 6 Samarinda Junior High School students regarding the importance of applying ethics in society through the provision of classical guidance services. The activity, which carries the theme "Ethics in Society: Fun Friends Are Not Toxic", was held for three days on May 14-16, 2025, with three main sessions lasting 150 minutes every day. The material provided includes the introduction of the concept of social ethics, identification of healthy and unhealthy associations, ethical values in Islam, and ethics of behavior on social media. Through participatory and reflective methods, students are invited to actively discuss, conduct social simulations, and reflect on the values learned. The results of the evaluation showed an increase in student understanding, changes in social attitudes, and openness in communicating with guidance and counseling teachers.

Business ethics form the moral foundation that guides corporate operations and stakeholder interactions, fostering trust, strengthening relationships, and promoting long-term business sustainability. In the digital industry, the application of business ethics has become increasingly critical due to the complexity of interactions among companies, partners, and customers. PT GoTo Gojek Tokopedia Tbk, established through the 2021 merger of Gojek and Tokopedia, faces substantial challenges in upholding ethical principles amid the dynamic landscape of Indonesia’s digital economy. This study adopts a descriptive qualitative approach, utilizing observation and literature review, to examine the extent to which the implementation of business ethics at GoTo contributes to its corporate performance. The findings indicate that consistent ethical practices significantly enhance corporate reputation, improve customer loyalty, and foster a healthy work environment. The integration of fairness, honesty, transparency, and social responsibility has proven to be critical in ensuring corporate sustainability and growth within the competitive digital industry. This study underscores the imperative for companies to systematically embed ethical principles into all operational activities in order to address evolving regulatory frameworks, market competition, and rising societal expectations.

This research aims to analyse the interpretation and application of the element of deception by judges in cases of criminal fraud based on juridical considerations in court decisions, especially in the context of the legal relationship of agreements. In judicial practice, there is often an overlap between the realms of civil and criminal law, especially when a default is qualified as fraud. This raises legal issues that require consistent and rational juridical reasoning from judges. The urgency of this research lies in the need to understand how judges assess and interpret the elements of deceit that are often in a grey area, as well as how judges' discretion is used to integrate legal norms with a sense of substantive justice. The method used is a normative legal research method, with a statute approach, which examines the provisions in the old and new Criminal Code (KUHP) that are relevant to the element of deception. This research also uses a literature study and analysis of court decisions to strengthen the theoretical and practical basis. The novelty of this research lies in its focus on aspects of judges' juridical reasoning in interpreting the elements of deceit, not merely on procedural aspects or sociological phenomena, so that it is expected to contribute to strengthening the quality of legal considerations in criminal justice practice. This study recommends that law enforcement authorities adopt a more rigorous juridical reasoning approach in distinguishing between breach of contract and criminal fraud to prevent the criminalization of civil cases.
 
Penelitian ini bertujuan untuk menganalisis penafsiran dan penerapan unsur tipu muslihat oleh hakim dalam perkara tindak pidana penipuan berdasarkan pertimbangan yuridis dalam putusan pengadilan, khususnya dalam konteks hubungan hukum perjanjian. Dalam praktik peradilan, sering kali ditemukan tumpang tindih antara ranah hukum perdata dan pidana, terutama ketika suatu wanprestasi dikualifikasikan sebagai penipuan. Hal ini menimbulkan persoalan hukum yang memerlukan penalaran yuridis yang konsisten dan rasional dari hakim. Urgensi penelitian ini terletak pada kebutuhan untuk memahami bagaimana hakim menilai dan menafsirkan unsur tipu muslihat yang kerap berada di wilayah abu-abu, serta bagaimana diskresi hakim digunakan untuk mengintegrasikan norma hukum dengan rasa keadilan substantif. Metode yang digunakan adalah metode penelitian hukum normatif, dengan pendekatan perundang-undangan (statute approach), yang menelaah ketentuan dalam Kitab Undang-Undang Hukum Pidana (KUHP) lama dan baru yang relevan dengan unsur penipuan. Penelitian ini juga menggunakan studi pustaka dan analisis terhadap putusan pengadilan untuk memperkuat landasan teoritik dan praktis. Kebaruan dari penelitian ini terletak pada fokusnya terhadap aspek penalaran yuridis hakim dalam menafsirkan unsur tipu muslihat, tidak sekadar pada aspek prosedural atau fenomena sosiologis, sehingga diharapkan dapat memberikan kontribusi terhadap penguatan kualitas pertimbangan hukum dalam praktik peradilan pidana. Penelitian ini merekomendasikan agar aparat penegak hukum agar lebih mengedepankan penalaran yuridis yang mendalam dalam membedakan antara wanprestasi dan tindak pidana penipuan, guna mencegah terjadinya kriminalisasi terhadap perkara perdata.

The purpose of this study is to analyze the application of the principles of unlawful acts and environmental justice to companies, obstacles to law enforcement, and the monitoring and enforcement system related to environmental damage in Indonesia. Environmental damage caused by corporate activities is a global issue. Companies often ignore ecological impacts, threaten biodiversity, and harm surrounding communities, requiring strict law enforcement. Law enforcement against companies that damage the environment in Indonesia faces major obstacles, such as a lack of effective supervision, corruption, and political influence, which hinder corporate responsibility for environmental damage. This study offers a novel perspective by focusing on the legal responsibility of perpetrators of land damage, moving beyond previous research that primarily discussed the government's right to sue for unlawful acts. This study uses a normative juridical approach with analysis of legal regulations, principles of corporate responsibility, and environmental justice, using secondary data analyzed qualitatively. The results indicate that corporate responsibility for environmental damage from the perspective of unlawful acts and environmental justice in Indonesia still faces obstacles. Although regulations govern corporate responsibility, applying the principles is ineffective due to political influence, corruption, and weak monitoring. Strengthening regulatory institutions, implementing transparent reporting systems, and imposing stricter sanctions on companies damaging the environment are important steps to ensure justice. Developed countries can serve as models for improving Indonesia’s law enforcement system.

Evaluating changes in public perceptions of gold investment before and after price increases is the objective of this study. The background of this study rests on the assumption that gold price volatility can affect an individual's interest in and view of gold as an investment vehicle. This study used a quantitative approach by distributing questionnaires using a Likert scale to 50 respondents, the results of which were analyzed using the paired sample t-test. The results of the analysis show that there is no statistically significant difference in people's perceptions before and after the gold price increase (significance value 0.363 > 0.05). The findings of this study indicate that the public still views gold as a safe and stable investment asset in the long term, regardless of price changes in the short term. The results of this study can be used as a reference by market participants and financial planners to understand the tendency of public attitudes towards gold investment.

This study is entitled "The Role of Parboru and Hula-Hula in the Settlement of Divorce Disputes in Batak Toba Customs". The main focus of this study is to analyze the role and position of Parboru (the woman's family) and Hula-Hula (the wife's family) in the divorce settlement process according to Batak Toba customs. This study also presents the dynamics of the interaction of the two elements in customary mediation, as well as how customary values ​​and norms are implemented to maintain the harmony and dignity of the extended family. The method used in this study is a qualitative method with a descriptive approach. Data obtained through interviews and library studies of relevant literature on Batak Toba customary law, Dalihan Na Tolu, and the role of Parboru and Hula-Hula in traditional ceremonies and the resolution of marital conflicts in Batak Toba customs. The results of the study indicate that Hula-Hula has a central position as a decision maker and mediator, while Parboru plays a role as a technical implementer, mediator, and balancer in the customary deliberation forum. The active involvement of both parties is very important to ensure that the divorce process runs according to customary norms and maintains the social harmony of the Batak Toba community. This study is expected to enrich the literature on Batak customary law and become a reference for students, the community, and customary leaders in understanding the importance of the role of kinship in resolving divorce.

This study aims to examine the legal aspects of copyright infringement in the digital context, particularly under Law Number 28 of 2014 on Copyright, and analyze its implications for companies that utilize digital content without authorization. The urgency of this research stems from the increasing prevalence of unauthorized use of protected content, particularly in the hospitality sector, where visual media play a central role in marketing strategies. The study employs a normative juridical approach by analyzing relevant legislation and actual court decisions, focusing on the copyright dispute between PT OYO Rooms Indonesia (OYO) and PT Duit Orang Tua (DOT). In this case, OYO allegedly used and modified DOT's photos without permission for commercial promotion purposes on various online platforms. The court found OYO guilty of copyright infringement in decision Number 45/Pdt.Sus-HKI/Hak Cipta/2020/PN Jkt.Pst, and this decision was upheld by the Supreme Court in cassation Number 649 K/Pdt.Sus-HKI/2021. The research highlights that the Indonesian legal framework has been able to provide effective protection to legitimate copyright holders. The novelty of this study lies in its doctrinal analysis of a real-world judicial decision, offering insights beyond the theoretical approaches in previous literature. The study concludes that Indonesia's copyright regime has proven effective in this case and finds that corporate responsibility and due diligence are key in preventing infringement. The study recommends that digital platforms and business actors strengthen their internal compliance systems to mitigate legal risks and promote responsible content usage.
