The POSEIDON 2025 program is a community service initiative focused on enhancing environmental resilience and improving the welfare of coastal communities in Kalijaga Hamlet. The program began with a series of surveys aimed at identifying environmental conditions, social dynamics, and the main issues faced by local residents. The survey results revealed rapid sedimentation, accumulated waste along the coastline, and seawater intrusion that rendered groundwater unfit for consumption. Based on these findings, several solution-oriented activities were designed, including the installation of a water filter in the mosque, seminars and socialization on the functions and conservation of mangroves, the planting of 100 mangrove seedlings, the restoration of the Community Hall with the addition of an environmental-themed reading corner, and a beach clean-up activity. The program was carried out over three days with the involvement of local residents, students, academics, and social organizations. The implementation results showed an increase in public awareness of the importance of protecting mangrove ecosystems and coastal cleanliness, improved access to clean water, and enhanced environmental literacy among children. This program demonstrates that interdisciplinary collaboration and active community participation play a vital role in achieving sustainable and resilient coastal development.

The study titled “Judges’ Speech Acts in Handling Criminal Cases at the Gorontalo District Court” aims to describe the forms, functions, and meanings of speech acts used by judges in leading court sessions. The introduction emphasizes the importance of language in judicial processes to establish effective, fair, and authoritative communication among judges, defendants, prosecutors, and legal counsels. This study employs a descriptive qualitative method with a pragmatic approach. Data were collected through direct observation, documentation, and transcription of court proceedings. The analysis is based on Austin and Searle’s speech act theory, which includes locutionary, illocutionary, and perlocutionary acts. The results show that judges use various types of speech acts, such as directive, declarative, representative, and expressive acts. Illocutionary acts, particularly commands, questions, and assertions, are the most dominant. Their functions are not only to direct the course of the trial but also to maintain order, emphasize legal aspects, and clarify understanding among the parties involved. In conclusion, judges’ speech acts serve as strategic communicative tools with pragmatic power that influence the course of the trial and determine the effectiveness and fairness of the judicial process.

This study examines the role of the Constitutional Court of Indonesia (Mahkamah Konstitusi/MK) as a positive legislator through the lens of the living constitution approach, which conceptualizes the constitution as a dynamic and evolving document responding to social and political change. The main problem addressed is the extent to which the MK’s judicial activism in interpreting and even creating new legal norms aligns with constitutional principles, democratic legitimacy, and the balance of powers between the judiciary and the legislature. The objective of the research is to analyze how the MK’s progressive interpretations have transformed it from a negative legislator—which merely annuls unconstitutional laws—into a positive legislator that effectively fills legal gaps and constructs new constitutional meanings. Using a normative juridical method combined with case study analysis, this research explores key constitutional decisions, focusing on cases where the MK extended its interpretive authority beyond mere judicial review. The findings reveal that the MK, through the living constitution approach, justifies its role as a positive legislator by invoking principles of constitutional morality, justice, and responsiveness to societal evolution. However, this judicial creativity also generates tension with legislative supremacy and may risk overstepping the boundaries of judicial function. The synthesis of findings suggests that the MK’s transformation embodies the dynamic interplay between constitutional text and social context, reinforcing the adaptability of Indonesian constitutionalism. The study concludes that while the MK’s position as a positive legislator under the living constitution paradigm strengthens constitutional justice and protects citizens’ rights, it must remain anchored in checks and balances to prevent judicial overreach and preserve democratic legitimacy.

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disorder that presents significant diagnostic challenges due to its heterogeneous clinical manifestations and symptom overlap with other neurological conditions. Early and accurate diagnosis is critical for initiating timely interventions and improving patient outcomes. Traditional diagnostic approaches rely heavily on clinical expertise and manual interpretation of neuroimaging data, such as structural MRI, Diffusion Tensor Imaging (DTI), and functional MRI (fMRI), which are inherently time-consuming and prone to interobserver variability. Recent advances in Artificial Intelligence (AI) and Deep Learning (DL) have demonstrated potential for automating neuroimaging analysis, yet existing models often suffer from limited generalizability across modalities and datasets. To address these limitations, we propose a Transformer-augmented deep learning ensemble framework for automated ALS diagnosis using multi-modal neuroimaging data. The proposed architecture integrates Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), and Vision Transformers (ViTs) to leverage the complementary strengths of spatial, temporal, and global contextual feature representations. An adaptive weighting-based fusion mechanism dynamically integrates modality-specific outputs, enhancing the robustness and reliability of the final diagnosis. Comprehensive preprocessing steps, including intensity normalization, motion correction, and modality-specific data augmentation, are employed to ensure cross-modality consistency. Evaluation using 5-fold cross-validation on a curated multi-modal ALS neuroimaging dataset demon-strates the superior performance of the proposed model, achieving a mean classification accuracy of 94.5% ± 0.7%, precision of 93.9% ± 0.8%, recall of 92.9% ± 0.9%, F1-score of 93.4% ± 0.7%, spec-ificity of 97.4% ± 0.6%, and AUC-ROC of 0.968 ± 0.004. These results significantly outperform baseline CNN models and highlight the potential of transformer-augmented ensembles in complex neurodiagnostic applications. This framework offers a promising tool for clinicians, supporting early and precise ALS detection and enabling more personalized and effective patient management strategies.

The braking system was a crucial component in ensuring the safety of motor vehicles on the road. Brake failures, such as brake fade or total malfunction, could result in fatal accidents. Therefore, an accurate and realistic testing method was necessary to measure the effectiveness of a vehicle’s braking system. This study aimed to develop a deceleration measuring device based on GPS, which could be used in road test methods. The device was designed using an ESP32 microcontroller combined with a BN-220 GPS module, RTC real-time clock sensor, 16x2 LCD, thermal printer, and microSD storage media. Testing was conducted on a Mitsubishi L300 vehicle at the Depok Beach runway in Yogyakarta, with initial speed variations ranging from 10 to 80 km/h. Calibration results showed that the device had an accuracy of 99.64% with an average error of 0.36%. Meanwhile, the test results recorded deceleration values ranging from 0.74 to 3.26 m/s², depending on the initial speed and braking conditions. Based on these findings, the developed device proved to be accurate and feasible as an alternative method for field testing of braking systems.

This study aimed to examine the ecological and socio-economic aspects of mangrove utilization in Nasem Village, Merauke Regency, Papua Selatan. The ecological assessment included mangrove species composition, regeneration potential, health status, and Importance Value Index (INP). Socio-economic data were collected through questionnaires and focus group discussions with 30 respondents. The results showed that  Avicennia marina  had good regeneration potential and dominated the community with the highest INP (1.13), while  Avicennia alba  was categorized as new regeneration with a low INP (0.31). The health status of both species was classified as rare/damaged according to national standards, indicating the need for restoration. From a socio-economic perspective, 90% of respondents utilized mangroves for firewood and fisheries, and 95% stated that mangroves significantly contributed to household income, although 83% earned less than IDR 1,000,000 per month. Most respondents (85%) recognized the ecological functions of mangroves, but anthropogenic pressures such as sand mining remained major threats. These findings highlight the urgent need for community-based mangrove management that integrates ecological restoration with sustainable economic development. The study provides scientific evidence to support policy recommendations for sustainable coastal zone management in Merauke.

This article analyzes the fundamental differences between the mechanisms of fund collection and fund distribution in Islamic banks and conventional banks in Indonesia, based on DSN-MUI Fatwas and banking regulations. In general, both types of banks serve the same function—to collect and distribute funds to support economic activities. However, the main distinction lies in their operational principles. Conventional banks operate using a fixed interest system, establishing a creditor–debtor relationship. In contrast, Islamic banks operate based on Sharia principles that prohibit riba (usury). In fund collection, conventional banks use interest-based savings and deposit products, while Islamic banks apply Wadiah (safekeeping) and Mudharabah (profit-sharing investment) contracts. Regarding fund distribution, conventional banks provide interest-bearing loans, whereas Islamic banks offer financing through Sharia contracts such as Murabahah (cost-plus sale), Musyarakah (partnership), Mudharabah (profit-sharing), and Ijarah (leasing), emphasizing cooperation and risk-sharing. Although Islamic banking is regulated under Law No. 21 of 2008 and DSN-MUI Fatwas, it still faces several challenges, including the dominance of Murabahah financing and the low level of public literacy regarding Islamic financial systems.

The COVID-19 pandemic triggered a significant transformation of performing arts in Aceh, particularly through Taman Budaya Aceh, which shifted its stage activities into digital formats. This study aims to describe the processes of digital mediation, changes in production formats, audience engagement patterns, and the archival function of cultural performances through Taman Budaya Aceh’s official YouTube channel. Using a qualitative descriptive case study design, the research analyzed 12 performance videos produced and uploaded between 2020–2022 through visual and narrative analysis. The findings reveal three key aspects: first, the shift from offline to online production created a new aesthetic based on camera work and editing; second, audiences transformed into mediatized participants through comments, likes, and replays; third, digital platforms functioned as cultural repositories, expanding access and strengthening the preservation of performances. These findings highlight that digitalization of performing arts is not merely an emergency response, but an integral part of constructing a sustainable arts ecosystem in the digital disruption era.

Individuals over the age of 60 are vulnerable to a decline in body functions, including nervous system functions that can lead to cognitive impairment and dementia. This condition can cause the elderly to be unable to perform activities, thereby impacting their well-being and happiness. One effort to overcome this is through crossword puzzle therapy to stimulate and improve cognitive function. To implement research-based nursing actions for the elderly with decreased cognitive function. The design used in this final nursing thesis is a case study with an intervention involving crossword puzzle therapy. The number of respondents was four, with the intervention conducted over one week at a frequency of twice daily, starting from June 22–28, 2025, and continuing from June 28–July 5, 2025, at the Dharma Bhakti Elderly Care Home KM 7 Palembang. After undergoing crossword puzzle therapy for one consecutive week, the four elderly participants showed changes in their MMSE scores at the final meeting: Mrs. L from 20 to 22, Mrs. M from 18 to 20, Mrs. A from 21 to 22, and Mrs. N from 22 to 23. Here was an improvement in cognitive function before and after crossword puzzle therapy was administered to the four participants. The application of this EBP is expected to add information about the provision of crossword puzzle therapy in the elderly with cognitive decline.

This study examines youth slang (Jugendsprache) in the film Into the Beat (2020) through semantic and morphological approaches. The background of the research is based on the phenomenon of youth language development, which is dynamic, creative, and rich in socio-cultural meaning, yet often difficult for foreign speakers to understand. Youth language is chosen as the object of study because it reflects identity, group solidarity, and the communicative creativity of young people, and frequently appears in media, particularly films. The theoretical framework refers to experts’ perspectives on the characteristics of youth language, including the use of Anglicisms, abbreviations, metaphorization, and the formation of neologisms. The research method applied is descriptive qualitative, with data sources taken from the dialogues and subtitles of the film Into the Beat. The analysis is carried out based on Helmut Henne’s theory of youth language characteristics. The results reveal that youth slang in the film functions not only as a means of communication but also as a medium of emotional expression, lifestyle, and identity construction among German adolescents. Vocabulary such as alter, bro, krass, cool, and scheiße demonstrates creativity in morphological processes, including abbreviation, prefixation, and borrowing from foreign languages. The study concludes that youth slang plays an essential role in shaping characters, inter-character relationships, and the authenticity of the storyline. Furthermore, youth language reflects the evolving cultural and social dynamics of adolescents. This research is expected to contribute to linguistic studies, particularly semantics, and to serve as a valuable resource in German language learning by expanding vocabulary and fostering an understanding of authentic communication patterns among German teenagers.

Islamic insurance (takaful) is a financial instrument that functions not only as risk protection but also as an investment tool based on sharia principles. So far, the most commonly applied tijarah contracts in Islamic insurance are limited to wakalah bil ujrah and mudharabah. In fact, the development of modern society’s needs requires the diversification of contracts so that the offered products become more varied and competitive. This study aims to analyze the potential optimization of other tijarah contracts, such as musyarakah, murabahah, ijarah, and istishna’, in the development of Islamic insurance products. The research method used is library research with a descriptive qualitative approach, which involves reviewing literature, journals, DSN-MUI fatwas, and related regulations. The findings indicate that the application of other tijarah contracts has the potential to enrich Islamic insurance product variations, enhance transparency in fund management, and strengthen the competitiveness of Islamic insurance compared to conventional insurance. Furthermore, the diversification of contracts can provide solutions to the limited and monotonous business models of Islamic insurance. However, several challenges arise, including the absence of specific regulations governing these contracts, limited public understanding, and technical complexities in implementation. This study recommends the active role of regulators, especially DSN-MUI and OJK, in formulating clearer regulations and encouraging Islamic insurance companies to innovate by applying diverse sharia-based contracts. Thus, the optimization of other tijarah contracts will not only strengthen the existence of Islamic insurance in Indonesia but also fulfill society’s demand for financial products that are halal, innovative, and competitive.

This study examines the legal protection regarding the cancellation of unused trademarks through a case study of the Supreme Court Decision No. 264 K/Pdt.Sus-HKI/2015 between IKEA Systems BV and PT Ratania Khatulistiwa. Trademarks play a vital role in modern trade, functioning not only as product identities but also as guarantees of quality and reputation with significant economic value. Law No. 15 of 2001 stipulates that a trademark may be cancelled if it is not used for three consecutive years, aiming to prevent speculative practices and pseudo-monopolies. However, this provision raises issues when applied to well-known trademarks that require longer periods to penetrate domestic markets. Using a literature review approach, this research analyzes legal norms, doctrines, and court decisions, while comparing them with international practices. The findings reveal that Indonesian law prioritizes the use requirement principle over the global reputation of a trademark. The Supreme Court’s decision to cancel the IKEA trademark demonstrates Indonesia’s legal orientation towards domestic legal certainty, yet it also creates challenges in maintaining a conducive investment climate. Therefore, trademark regulations need to be reformed to become more adaptive to globalization dynamics while balancing the interests of trademark owners, local businesses, consumers, and the state.

Physiotherapy plays an important role in promotive and preventive efforts through education for the community, including children’s health posts (posyandu). Children aged 1–5 years often experience eating difficulties that reduce appetite, increasing the risk of malnutrition and growth retardation. Low appetite is often related to oral-motor function disorders, such as difficulty chewing or swallowing. This activity aimed to increase mothers’ knowledge about oral-motor-sensory stimulation as an effort to improve children’s appetite. The community service program was conducted at Posyandu RW 02, Kota Lama Subdistrict, Malang City, involving 15 mothers or caregivers of toddlers. The method included physiotherapy counseling using interactive discussions and poster media, with knowledge evaluation through pre-test and post-test. The results showed a significant improvement in participants’ knowledge, from 0% in the pre-test to 85% in the post-test. This counseling effectively enhanced mothers’ understanding and practical skills in performing oral-motor-sensory stimulation independently at home. With regular implementation, this stimulation is expected to increase children’s appetite, improve nutritional status, and support optimal growth and development. Moreover, it reinforces the role of physiotherapy in preventing nutritional problems and improving the quality of life of children from an early age.

This study aims to explore how Indonesia's auspicious legal framework supports the establishment and functionality of cooperatives and identify challenges to its implementation. Used in this study is a qualitative Systematic Literature Review (SLR), whose collection and review of literature were conducted through various academic sources with complementary legislation. The results of the research indicate that in spite of the existence of formal arrangements and rules for institutional factors and cooperative health assessments, field practice is weak due to lack of understanding, socialization, and effective supervision. Social and geographical diversity and legal limitations are also major concerns in the realization of adaptive and sustainable cooperatives. Therefore, the regulatory approach has to be reformed and the institutional strength of cooperatives increased to guarantee more effective functioning as well as in accordance with cooperative principles.

This study departs from the urgency of early childhood religious education as the foundation for shaping religious and moderate character. The lack of Qur’an learning facilities and qualified teachers in Karang Mulya Village has hindered children aged 6–10 years in mastering Qur’anic literacy skills, even though this stage is considered a golden period of cognitive, affective, and psychomotor development. To address this issue, the research employed a qualitative descriptive method combined with a Project-Based Learning (PjBL) approach, which allowed the teaching process to be linked with practical and contextual activities. Data were collected through direct observation, structured interviews with parents and teachers, and careful documentation of student progress. The analysis was carried out through systematic steps of data reduction, presentation, and conclusion drawing. The findings reveal significant improvements in children’s ability to recognize, read, and write hijaiyah letters, although variations remain, particularly in creativity and independence. Furthermore, Qur’anic literacy activities meaningfully contributed to strengthening the understanding of religious moderation values, such as national commitment, tolerance, anti-violence, and acceptance of local culture. In conclusion, student service activities through Qur’anic literacy not only enhanced technical skills but also functioned as an effective medium for building religious moderation foundations from an early age.

The poem “Mayat Politik Ditutupi Koran Pagi” by Afrizal Malna presents sharp social and political criticism through the use of irony and complex metaphors. This study aims to examine how these two linguistic devices are employed to reveal the socio-political realities of post-reform Indonesia. Using a stylistic approach, the research explores the forms, functions, and meanings of irony and metaphor that appear within the poem’s structure. The analysis shows that irony serves to express dissatisfaction and satire toward political conditions that appear orderly but are actually filled with deception and manipulation. Meanwhile, metaphor provides a symbolic depiction of the role of mass media as an instrument of power that conceals the true political reality behind public discourse. Through the interplay of these two stylistic elements, Afrizal Malna succeeds in presenting a poetic representation of society’s anxiety over media domination and the blurring line between truth and political interest. This study is expected to enhance the understanding of literature’s role as a reflective and critical medium in uncovering the relationship between language, power, and ideology within Indonesia’s socio-political dynamics.
