Object-Oriented Programming (OOP) is a programming paradigm that emphasizes the use of objects and classes to build modular and maintainable software. One of the fundamental concepts in OOP is polymorphism, which is the ability of objects from different classes to respond to the same method in different ways. This study aims to analyze the effectiveness of the polymorphism concept in directing software design in terms of code structure, development utility, and maintenance efficiency. The research method used is a literature study and program code simulation using a procedural approach compared to an object-oriented approach that applies runtime polymorphism. The results of the analysis show that the use of polymorphism can significantly reduce the number of lines of code, logical structure traffic, and facilitate feature expansion without the need to change existing code. Thus, polymorphism has proven effective in improving readability, reusability, and scalability of software design.

This Community Service Program (PKM) was implemented in response to the high usage of social media among students, particularly Instagram, which often becomes a platform for cyberbullying. This phenomenon becomes increasingly complex when students come from diverse cultural backgrounds. Comments or posts considered normal in one culture may be perceived as offensive in another. A lack of cultural sensitivity often triggers digital conflict and bullying, which can negatively impact students' mental health. This PKM aims to improve students’ understanding of the dangers of cyberbullying and the importance of cross-cultural communication ethics. The program began with a pre-test to assess participants' initial knowledge, followed by an interactive seminar discussing the concepts of cyberbullying, digital ethics, and real-life case studies. Students then engaged in group discussions and simulations, where they analyzed problematic digital content and formulated empathetic, constructive responses. At the end of the activity, a post-test was conducted to evaluate the program’s effectiveness. The results showed a significant improvement in students’ awareness and attitudes. This program successfully encouraged students to be more thoughtful and responsible in their online interactions and to become change agents in creating a safer, more inclusive digital environment. The outcomes of this program include a scholarly publication, an educational video disseminated on social media, and quantitative data showing an increase in participants’ knowledge. Overall, this initiative contributes to strengthening multicultural digital literacy among today’s youth.

Law Number 1 Year 2023 on the Criminal Code (KUHP) is a form of national criminal law reform that recognises the existence of customary criminal law. However, it has not been regulated in detail how the implementation and position of customary criminal law as a reason for criminal prosecution, and there are fundamental differences between the two concepts of the legal system. The problems in this research are how the position between customary criminal law and national criminal law in the new Criminal Code, how the legal certainty of the regulation of customary criminal law in the new Criminal Code, and how the challenges in enforcing customary criminal law using the current criminal justice system in Indonesia. This research uses normative juridical method with regulatory and conceptual approaches. The results show that the applicability of customary criminal law is limited to the area where the law lives and applies to customary criminal acts committed in the area where the law lives. The position of customary criminal law can be valid as a reason for criminal prosecution if the customary law that is still alive in the community has been stipulated in the form of Regional Regulations, and customary offences that are similar to offences in the New Criminal Code will be ruled out, and the classification of customary sanctions as additional sanctions, positioning customary penalties to be complementary or secondary, because additional sanctions can only be imposed together with the main sanctions. Legal certainty towards the regulation of customary criminal law is highly dependent on the formulation of the elements of each offence of customary criminal law stipulated in regional regulations. The current criminal justice system in Indonesia (KUHAP) cannot realise the objectives of customary criminal law. The objectives, characteristics, and procedures in the concept of customary law are contrary to those in the criminal justice system. Restorative Justice can be utilised as an alternative to the settlement of customary criminal cases when the New Criminal Code comes into effect.

This research explores Ōta Shōgo’s The Water Station using a biographical lens, concentrating on three key aspects of absurdist theater: the Anti-Hero, Anti-Dialogue, and Anti-Climax. Breaking away from conventional storytelling methods, the play introduces a cast of anonymous characters who move gradually and silently across the stage, briefly stopping at a leaking water pipe. These characters represent the Anti-Hero—individuals lacking a distinct purpose, choice, or identity. The performance's lack of spoken words introduce a powerful Anti-Dialogue component, substituting conversation with silence and physical gestures, which symbolically mirrors the playwright’s experiences of trauma and disillusionment following the war. Moreover, the story does not follow a typical climax or conclusion, utilizing Anti-Climax to highlight the meaningless repetition inherent in human life. Through an examination of Ōta’s personal history—especially his experiences of displacement during World War II and his interest in the concepts of time, slowness, and stillness—this paper illustrates how these influences shaped the play's form and tone. The study emphasizes that non-Western absurdist art can arise from deeply personal and historical backgrounds. Ultimately, The Water Station creates a reflective theatrical experience where silence communicates more than spoken words, encouraging viewers to engage with the themes of emptiness, ambiguity, and the quiet beauty of existence.
