This article discusses the leva mass in Lamalera as one of the examples of the inculturation of the Catholic faith in local culture on the island of Lembata, East Nusa Tenggara. Inculturation is understood as a process of encounter between faith and culture, so that the proclamation of the gospel can be deeply lived in the context of the life of the local people. Through the leva mass, cultural elements such as sea symbols, boats (tena), traditional dances, traditional clothing, and regional songs are harmoniously integrated into the liturgy of the Catholic Church. For the Lamalera community, the sea is not only a source of livelihood, but a symbol of God's presence and power that blesses and protects human life. The celebration of the Mass emphasizes that God is present not only in the church building, but also in every aspect of human life, including work. The Leva Mass can also strengthen the spirit of brotherhood, solidarity, and the responsibility of the people towards His created nature. The people learn to be grateful for marine products, respect the environment, and work with the spirit of love and sacrifice. Thus, the leva mass is not just a religious ritual, but also a faith and cultural education that helps the people in understanding their call to live in harmony with nature and the will of God. Through the Mass of Leva, the Church in Lamalera portrays the living face of faith, the source of the gospel but rooted in the local culture.

Power transformer theft, a pervasive issue disrupting critical infrastructure, necessitates the development of cost-effective and energy-autonomous security solutions. This paper presents the design and implementation of a detection-focused anti-theft framework that integrates a Raspberry Pi Zero W, camera module, and passive infrared (PIR) motion sensors powered by a solar system for continuous monitoring. The system is designed for remote, off-grid deployment, utilizing a headless Raspberry Pi powered by a 5V solar panel and power bank to ensure energy autonomy. Upon motion detection, captured images are processed on the edge device using OpenCV’s Haar Cascade classifier, optimized for upper-body detection to minimize false positives and verify human presence. Captured images are processed locally on the edge device using OpenCV’s Haar Cascade classifier to confirm human presence before an alert is sent to the mobile application, emphasizing real-time operation and low latency. Once an intrusion is confirmed, the images are saved locally and uploaded via the Secure File Transfer Protocol to a custom-developed Android application. The app provides a dedicated remote monitoring interface, enabling secure file transfer and system access, while providing users with immediate notifications and image management capabilities. The system emphasizes low power consumption, real-time operation, and low deployment cost. Tests over 200 triggered events under varied environmental conditions achieved 90% detection accuracy with an average latency of 4.5 s. Solar autonomy was maintained for approximately 24 h under normal operation. It is concluded that the integration of solar power, edge computing of images, and mobile monitoring provides a feasible, scalable, and financially viable framework for securing transformers, especially in resource-constrained environments.

This study delves into the linguistic and ideological dimensions of cyberbullying discourse directed at TikTok creator Putri Padang within the framework of Critical Discourse Analysis (CDA). In Indonesia’s digital landscape, TikTok has become one of the prominent platform for self-expression and cultural performance, yet it also serves as a site for public shaming and moral policing. Drawing on Fairclough’s (1995) three-dimensional model, this qualitative research analyzes fifty hate comments collected from several TikTok videos featuring Putri Padang to uncover how language reproduces power relations and cultural ideologies. The findings reveal that hate comments are not random acts of aggression but structured discursive practices characterized by repetition, labeling, and moral judgment. Linguistic strategies such as mockery, objectification, and intertextual humor—exemplified by terms like “muka kotak” and “Adudu”—function as mechanisms of symbolic domination, reinforcing gendered and regional hierarchies. Moreover, the comments often invoke patriarchal values and cultural authenticity to moral criticism, positioning the target as a violator of feminine and cultural norms. The research contributes to cyber-discourse studies by extending into multimodal contexts and emphasizing the need for culturally grounded approaches to online gender-based violence.

This study aims to analyze gender representation in the L’Oréal Paris Elvive Extraordinary Oil advertisement using Sara Mills’ Critical Discourse Analysis (CDA) approach. The advertisement functions not only as a promotional medium for hair-care products but also as a site of meaning production that shapes social constructions of beauty, women’s roles, and power relations within society. Through the visuals and narrative presented, women are portrayed as the central focus as well as symbols of ideal beauty, characterized by shiny hair, an elegant appearance, and a confident demeanor. The analysis shows that women in the advertisement are positioned primarily as visual objects, while the L’Oréal Paris brand takes the role of the subject that provides solutions to women’s problems—specifically damaged hair. The use of the iconic slogan “Because you’re worth it” constructs a discourse suggesting that women’s self-worth and personal value are closely tied to physical appearance, especially the condition of their hair. Thus, the advertisement not only delivers commercial messages but also carries ideological implications about beauty standards that women are expected to meet. This study concludes that advertising plays a crucial role in reproducing contemporary gender norms and influences how society interprets women’s identity and value through the visual representations it presents.

This study examines the implementation of Green Disaster Management (GDM) policies by the Surabaya City Disaster Management Agency (BPBD) as a means to enhance disaster resilience through environmental sustainability. The research analyzes the integration of GDM principles across all phases of the disaster cycle pre-disaster, during response, and post-disaster recovery. Data was collected through in-depth interviews with key informants, participant observation, and document analysis at BPBD and pilot project sites, including mangrove conservation areas, green emergency posts, and eco-friendly reconstruction sites. The findings indicate that Surabaya has demonstrated significant commitment to embedding sustainability into disaster management through community education, environmentally friendly logistics, and eco-based mitigation measures. Nonetheless, challenges persist, such as limited funding, resistance from developers, logistical constraints, and societal perceptions favoring immediate response over environmental considerations. During disaster response, innovations such as solar-powered emergency equipment and waste segregation practices are being adopted, but their widespread application remains hampered by resource limitations. Post-disaster, efforts in eco-friendly reconstruction and reforestation programs have shown promising results but require enhanced public awareness and long-term maintenance. The success of GDM implementation depends on effective inter-agency coordination, political commitment, and community engagement. Despite progress, hurdles related to budget constraints, social resistance, and knowledge gaps fully hinder the adoption of green approaches. This study highlights the importance of strategic collaboration, policy support, and community participation to mainstream sustainability in disaster management continuously. Strengthening these aspects will not only improve Surabaya's disaster resilience but also contribute to sustainable urban development aligned with global frameworks such as the Sendai Framework for Disaster Risk Reduction.

Here, it is examined how language is employed as a weapon on the internet by means of the illocutionary acts in Bhad Bhabie's 2023 diss track "Ms. Whitman." According to J.L. Austin's and John Searle's Speech Act Theory, the paper categorizes the lyrics of the song into the various kinds of illocutionary acts-assertives, directives, commissives, expressives, and declaratives to determine how word aggression is an instrument of cyberbullying. Through qualitative text analysis, the study reveals expressive and assertive acts most prominent in the lyrics to disseminate defamatory claims, insults, and emotional harm against the object of attack Alabama Barker. Commissive and directive acts, on the other hand, serve to threaten, command, and dominate. The analysis shows how these speech acts collectively construct a model of systematic online verbal attack under the guise of musical performance. The findings show how music culture will tend to normalize aggression, make boundaries between entertainment and harassment opaque, and place audiences' understanding of digital communication ethics. The conclusion synthesizes the recommendation of media education as a means to enable listeners to critically understand the linguistic power of such content.

Digital transformation is reshaping the way economic value is created, exchanged, and governed across borders. This study aims to analyze how digital transformation redefines the paradigm of business law in the era of globalization, as well as the interaction between business law and global regulatory politics in responding to the challenges of the digital economy. A normative legal approach is employed, grounded in the analysis of digital business law regulations within the global political-economic system. Data is collected through literature review of statutory frameworks, international policy instruments, and scholarly works. The findings reveal that digital transformation not only changes how transactions are conducted, but also reconfigures the locus of economic power through the control of data, algorithms, and digital platform infrastructure. Consequently, the legal paradigm shifts from merely regulating market actors’ behavior to designing a digital justice architecture that emphasizes accountability, algorithmic transparency, interoperability, and contestability. At the global level, the interaction between business law and digital regulatory politics reflects ongoing tensions between market openness and data sovereignty producing regulatory pluralism while simultaneously encouraging convergence toward principles of fair, adaptive, and responsive digital governance. This study concludes that business law in the digital era must serve not only as a regulatoryinstrument governing transactions, but as an architect of the global economic order one that safeguards innovative growth without compromising market fairness and fundamental rights, while enabling the strengthening of adaptive national regulatory frameworks aligned with evolving global dynamics.

This research examines the complex dynamics of Islam-West interactions through a historical-analytical approach, focusing on the evolution of these relations from medieval encounters to contemporary developments. Using qualitative methods through extensive literature review and critical discourse analysis, this study analyzes the multifaceted nature of Islam-West relations across historical periods, contemporary contexts, and emerging paradigms of engagement. Findings reveal that Islam-West interactions have evolved through distinct historical phases: medieval encounters characterized by both intellectual exchange and military conflicts, colonial experiences that created lasting power asymmetries, and contemporary dynamics shaped by geopolitical tensions, migration patterns, and globalization. The research identifies three major contemporary challenges: persistent Orientalist and Islamophobic discourses, geopolitical conflicts intensifying civilizational narratives, and internal diversity within both civilizational spheres that complicates unified engagement. The study proposes a transformative model of Islam-West relations founded on shared ethical values, contextual understanding of religious texts, collaborative approaches to global challenges, and recognition of internal pluralism within both traditions. This research contributes to intercultural understanding by offering a nuanced historical perspective on Islam-West relations and establishing a theoretical framework for constructive engagement in an increasingly interconnected world

Indonesia's dependence on fossil energy, which reaches 98%, results in high CO₂ emissions and energy costs. This study aims to design a wind energy system to meet electricity needs at the Arafuru Field of the Indonesian Navy Academy (AAL), which is strategically located near the coast with adequate wind potential. A quantitative research method was used by collecting wind speed data for three months (January-March 2025) at coordinates 7.21755° S, 112.71022° E. The data shows an average wind speed of 2.32 m/s with unpredictable direction. Based on the analysis, the SH-X 10000 vertical wind turbine was selected as the most suitable solution. Calculation results show that one turbine unit can generate power of 104,999 watts, so to meet the total power requirement of 109,120 watts, at least 2 wind turbine units are needed. This system not only reduces dependence on PLN and fossil energy but also has the potential to reduce CO₂ emissions and can be utilized as a learning laboratory for AAL cadets. The implementation of wind energy at AAL's Arafuru Field is expected to be a concrete step in the transition towards renewable energy in the military environment.

Power transformers are crucial in the electrical distribution system, and their operational stability is significantly affected by load imbalance among phases. Load imbalance can lead to the flow of neutral current through the neutral conductor, causing additional power losses in the transformer. This study analyzes the impact of load imbalance on neutral current and power losses at Transformer 1 (30 MVA capacity, 70/20 kV) at the Bungaran Substation. Data such as phase current, neutral current, and power losses were measured at 12:00 and 21:00. At 12:00, the transformer’s full-load current was 839.17 A with a loading of 28.44% and a load imbalance of 0.74%, resulting in a neutral current of 4.36 A (1.83% of load current). The power loss due to neutral current was 12.64 W (4.36×10-5 %), and the loss due to neutral current flowing to the ground was 760 W (2.62×10-3 %). At 21:00, the full-load current decreased to 834.46 A, with a loading of 29.36% and a higher load imbalance of 1.36%. This caused a neutral current of 7.94 A (3.24%), with a power loss of 41.90 W (1.43×10-4 %) and a ground power loss of 2.52 W (8.60×10-3 %). The power losses were minimal compared to the transformer’s capacity, having little effect on system efficiency. However, maintaining load balance is essential for system efficiency and transformer longevity.

Inflation, unemployment, and deflation are three fundamental macroeconomic phenomena that are closely interconnected in influencing a nation’s economic stability. These variables illustrate the equilibrium between production capacity, consumption behavior, and government intervention in achieving sustainable economic growth. The main purpose of this study is to explore the interrelationship between inflation, unemployment, and deflation, and to assess their implications for Indonesia’s economic stability. This research applies a qualitative descriptive method, employing literature reviews, document analysis, and secondary data evaluation derived from credible institutions such as the Central Bureau of Statistics (BPS), Bank Indonesia (BI), and the Ministry of Finance. The results suggest that a moderate level of inflation can positively stimulate economic expansion through increased consumption and investment activities. In contrast, excessive inflation tends to erode consumer purchasing power and potentially elevate unemployment rates. Meanwhile, prolonged deflationary conditions may lead to a decline in product prices, reduced business profitability, and slower economic momentum. The interaction among these three factors is complex and dynamic, necessitating a coordinated balance between fiscal and monetary policies to safeguard overall economic stability. This study concludes that effective inflation control, job creation, and deflation prevention are critical elements in strengthening Indonesia’s long-term economic resilience.
