The use of gongs and drums in the liturgy of the Catholic Church in Timor is a tangible form of inculturation, which is a process of dialogue between faith and local culture that enriches the spiritual experience and strengthens the identity of the people. Gongs and drums, which in Timorese culture have a symbolic meaning as a means of communication with ancestors and a marker of unity, are presented in the liturgy as a means of spiritual and cultural expression, making the liturgy a meeting space between tradition and faith. This process not only adds an aesthetic dimension, but also deepens the spiritual appreciation of the people and strengthens the liturgical communion. However, inculturation also brings theological and pastoral challenges, such as the risk of syncretism and cultural abuse, so adequate pastoral assistance and liturgical education are needed in order for the process to maintain the integrity of the faith and the values of the liturgical screen. Thus, inculturation is carried out wisely as a means of establishing faith, strengthening the identity of the local Church, and deepening the spiritual experience of the people in the land of Timor.

Divorce has become an increasingly prevalent moral and social phenomenon within modern society, including among Christian communities, with profound implications for family structures, spiritual life, and the church’s testimony in the world. This study analyzes divorce from the perspective of Christian ethics, grounded in a theological and moral reflection on Matthew 19:1–12 as the biblical foundation for understanding marriage and faithfulness. The findings reveal that divorce is not merely a legal or social concern but represents a spiritual crisis and a failure to uphold the sacred covenant established by God. Contributing factors such as infidelity, domestic violence, economic pressure, and weak faith formation erode the moral values of love and fidelity. Christian ethics emphasizes love, forgiveness, and moral responsibility as fundamental principles for healing and reconciliation within broken relationships. The church is called to exercise pastoral responsibility through guidance, counseling, and restoration, fostering ethical awareness and marital integrity among believers. Thus, applying Christian ethics to the issue of divorce is essential for nurturing spiritual maturity, strengthening family unity, and preserving the moral witness of the Christian community.

This means that these factors were identified as factors influencing the development of the learning model.

This article raises the academic issue of the low contribution of education quality to economic development in several developing countries, including Indonesia. This problem arises due to limited investment in developing quality human resources. Education plays a strategic role in shaping the intellectual capacity, skills, and productivity of the workforce, which are the foundation of sustainable economic growth. The purpose of this study is to analyze the urgency of education in supporting economic development through the perspective of Human Capital Theory, which emphasizes the importance of investing in people as a primary development asset. This study uses a desk study method by reviewing various academic literature, previous research results, and reports from international institutions regarding the relationship between education and economic growth. The results show that education plays a crucial role in driving economic and social development through the development of competent human resources. Based on human capital theory, investment in education can improve individual capabilities and societal welfare. Developed countries such as Finland, Japan, and Singapore have successfully demonstrated that large budget allocations to the education sector can sustainably increase economic productivity. However, developing countries and Muslim countries still face obstacles such as unequal access, limited facilities, and low teaching quality. Meanwhile, education in Muslim countries needs to be strengthened through curriculum reform and improved teaching quality to produce a skilled and globally competitive generation.

This study aims to analyze the role of TikTok as a digital marketing tool in increasing the number of streams and musicians' income, with a case study of the viralization of the song "Mangu" by Fourtwnty. Using a qualitative approach with a case study method, this study explores the dynamics of the virality of music content on the TikTok platform and its impact on the digital music ecosystem. The results show that the virality of songs is not solely triggered by algorithms, but also by the power of emotional narratives, the relevance of lyrics to the user experience, and the active participation of the audience in the form of production. This phenomenon is driving cross-platform conversions, where TikTok users are switching to streaming services such as Spotify and YouTube, thereby increasing digital royalties and opening up live performance opportunities for musicians. Organic marketing strategies based on audience engagement have proven to be effective in creating broad and sustainable exposure, especially among the digital native generation. This research confirms that TikTok is not only an entertainment platform, but also a strategic medium in building music branding and monetizing works creatively. These findings provide important implications for independent musicians and the music industry in designing adaptive and participatory promotional strategies in an increasingly competitive digital economy.

This study aims to analyze the narrative dissonance in the corporate communication of the Aqua brand, especially in the context of the crisis of meaning that arises between claims of natural purity and technical findings related to the use of borewells in the production process. Using a qualitative approach through content and narrative analysis, the study integrates two main theoretical frameworks: the Narrative Paradigm (Fisher, 1984) and Image Repair Theory (Benoit, 1995). The analysis focused on how companies are building, maintaining, and renegotiating their corporate narrative amid public pressure and consumer expectations. The results show that the legitimacy crisis arises due to the symbolic mismatch between the narrative of "purity" communicated and the operational reality revealed to the public. This tension triggered a strategic response from the company in the form of public clarification, transparency of the production process, and repositioning of messages to restore consumer image and trust. This study confirms the importance of narrative coherence and reflexivity in corporate communications, especially in an era of digital openness that demands accountability and consistency between symbolic messages and tangible practices. These findings contribute to the study of crisis communication and brand image restoration strategies, as well as a reference for companies in designing ethical, transparent, and sustainable communication to maintain legitimacy and credibility in the eyes of the public.

Indonesia faces significant challenges in achieving sustainable development, particularly due to the negative environmental impacts of rapid economic growth, such as deforestation, air and water pollution, and the increase in greenhouse gas emissions. Green Bonds have great potential as a financial instrument to promote sustainable development in Indonesia.

The research method used in this study is a normative legal approach with a focus on laws and regulations (UU) and a library research method. Through this approach, the study analyzes relevant regulations and existing literature to explore the potential and challenges Indonesia faces in implementing green bonds, particularly in the infrastructure investment sector. The implementation of green bond investments in Indonesia, especially in the infrastructure sector, is a strategic step in line with efforts to achieve sustainable development. To achieve this, Indonesia must also consider integrating green bonds into broader development policies. This includes developing strategies that combine economic, social, and environmental aspects in the planning and implementation of infrastructure projects.

Illegal mining activities in Sebulu District have become a serious issue as they not only violate the law but also cause significant damage to public infrastructure such as village roads, bridges, and drainage systems, which are deteriorating due to heavy trucks transporting mining materials. Although Article 158 of Law Number 3 of 2020 concerning Mineral and Coal Mining stipulates strict sanctions, law enforcement remains weak. The main contributing factors are local community involvement, inadequate supervision by authorities, and social legitimacy that perceives mining as a normal activity. This study aims to analyze criminal liability for illegal mining offenders and to identify its social and environmental impacts in Sebulu District. The research applies a socio-legal approach that combines normative and empirical methods. The normative approach examines applicable legal provisions, while the empirical approach includes field observations, interviews with local officials and residents, and documentation of relevant regulations and events. The findings indicate that the most severe impacts are the deterioration of village roads and bridges and environmental degradation, such as changes in water color in nearby drainage channels. These conditions cause public concern and disrupt daily life. Weak law enforcement allows illegal mining to persist. Therefore, synergy among law enforcers, local government, and communities is needed to strengthen regulation enforcement and develop sustainable economic alternatives.
