Communication is a fundamental human need for conveying information and ideas. However, individuals who are deaf and mute face difficulties in communicating with the broader community that does not understand sign language. This study aims to design and implement a real-time static sign language translator into speech using five flex sensors, an MPU6050 sensor, a Raspberry Pi Pico, an ADS1115 ADC module, and a DFPlayer Mini module as the audio output medium. Testing results show that the device successfully recognizes finger movements and hand orientation. The system is capable of playing audio output corresponding to recognized gestures, with the shortest latency recorded at 1.1 seconds and the longest at 2.8 seconds, achieving a detection accuracy rate of 75% based on 60 tests across 12 sign words. This device supports the translation of 12 simple sign words. The implementation demonstrates potential as an assistive communication tool, although further development is needed to improve accuracy, expand vocabulary, and conduct trials directly with deaf or mute users.

Malang Regency is known as a strategic location with considerable potential as a tourism destination in Indonesia. According to data released by the Central Bureau of Statistics, Malang Regency has recorded 267 tourist destinations spread across 33 districts. This study uses data from one water tourism destination, referred to as Tourism Site X, which focuses on the management and development of recreational areas, including swimming pools, bathing facilities, water attractions, artificial lakes, as well as the management of recreational parks and family facilities such as playgrounds, seating areas, and recreational and educational facilities. Tourism Site X is located in Pakis District, Malang Regency. The reuse of treated wastewater as a non-potable water source for irrigating green open spaces represents a crucial strategic approach to conserving water resources, particularly in water tourism areas such as Tourism Site X, which require substantial water supplies. In practice, the wastewater generated in Tourism Site X mainly originates from domestic sources, including activities such as cleaning swimming pool areas and animal enclosures, toilet usage, and food court operations. This study aims to assess whether the quality of treated wastewater from the wastewater treatment process at Tourism Site X complies with the required standards for green open space irrigation, in accordance with the Regulation of the Minister of Environment/Environmental Control Agency of the Republic of Indonesia Number 11 of 2025 concerning Wastewater Quality Standards and Wastewater Treatment Technologies for Domestic Wastewater, as well as to identify parameters that need to be reduced or eliminated.

The development of information technology has given rise to a new form of business transaction: the electronic contract. This contract form replaces the traditional process that requires a physical meeting between the parties. However, questions arise regarding the validity of e-contracts from the perspective of Indonesian civil law, specifically based on Article 1320 of the Indonesian Civil Code (KUHPerdata) and the provisions of Law Number 11 of 2008 concerning Electronic Information and Transactions (UU ITE). This research aims to analyze the validity of electronic contracts as legally binding agreements and to assess the extent to which the ITE Law can serve as their legal basis. Using a normative juridical legal research method, the research results show that e-contracts are valid and binding as long as they meet the requirements for the validity of an agreement under Article 1320 of the Civil Code, namely consent, capacity, a specific object, and a lawful cause. The ITE Law expands the recognition of electronic evidence and digital signatures as valid evidence in civil law. Thus, electronic contracts have the same legal force as conventional contracts, as long as they meet the principles of free will and the integrity of a reliable electronic system.

Per capita expenditure is an important indicator of household welfare because it reflects the economic capacity and consumption patterns of the community, as explained in Engel's Law. In regions with diverse geographical characteristics such as Papua Province, spatial analysis is needed to understand the variations in expenditure between districts/cities and the differences between urban and rural areas. This study aims to analyze the spatial distribution of per capita expenditure percentages for food and non-food items in nine districts/cities in Papua Province during the 2022–2024 period. The research data was sourced from the National Socioeconomic Survey (Susenas). The methods used included quantile-based choropleth mapping using QGIS, attribute data merging through table joins, and Pearson's correlation test to evaluate the consistency of spending patterns between years. The analysis results show that food and non-food spending patterns were relatively stable during the observation period with high correlation values (r = 0,85–0,93), although spatial variations between regions were still apparent. Mamberamo Raya Regency consistently had the highest proportion of food spending (>68%), while Jayapura City showed the lowest proportion. These findings indicate spatial disparities related to urbanization levels and economic access. Spatial visualization proved effective in revealing regional disparity patterns that were not fully apparent through conventional statistical tables and has the potential to support the formulation of more evidence-based regional development policies.  

This study analyzes the contribution of the nighttime economy to the development of micro, small, and medium enterprises (MSMEs) in Pekanbaru City, particularly the culinary sector, which dominates nighttime economic activity. This research is motivated by the increasing public consumption at night, which shapes urban economic dynamics and requires effective public governance. The research method uses a qualitative approach through literature review and in-depth interviews with nighttime MSMEs to describe business conditions and governance challenges. The analysis is based on Adam Smith's Theory of Economic Growth, emphasizing capital accumulation, population growth, and technological advancement. The results show that nighttime economic activity generates high levels of consumption, which increases MSME income and enables capital accumulation for business development and product quality improvement. Urban population growth and the use of digital technology, including social media, delivery services, and digital payment systems, contribute to expanding market reach and improving business efficiency. However, MSME development in the nighttime economy remains constrained by limited access to capital, inadequate public infrastructure, and regulatory uncertainty. This study emphasizes the need for integrated local government policies.

This study aims to analyse the development and compare the legal politics of the Religious Court in Indonesia and Turkey. This study is library research with an interdisciplinary approach to historical-legal and comparative law research. This study presents a historical-legal perspective and a comparative analysis of the law to obtain similarities and differences in the legal politics of the Religious Court in Indonesia and Turkey. The legal politics of the Religious Court in Indonesia are divided into pre-Colonial, independence, and reform periods. In Turkey, the Religious Court is divided into three periods: before the Tanzimat, after the Tanzimat, and during Mustafa Kemal Atatürk's reforms. A comparative analysis of the law found that the Religious Courts in Indonesia and Turkey initially applied Islamic law. Still, later restrictions were placed on it in an attempt to abolish it. The difference is that the Religious Court in Indonesia still enforces Islamic law as a positive law in certain fields and regions. The Religious Court in Turkey was abolished and replaced by a regular Court based on European law. The existence of the Religious Court in Indonesia demonstrates the success of legal pluralism, while legal secularism has shifted legal pluralism in Turkey.

Urban poverty remains a complex development challenge in Indonesia, including in Jambi City. This study aims to examine the influence of education level and unemployment rate on the poverty level in Jambi City. A quantitative approach was employed using secondary cross-sectional data at the sub-district level for the year 2024 obtained from the Central Bureau of Statistics. The dependent variable is the poverty rate, while the independent variables consist of the open unemployment rate and education level, proxied by the percentage of the population with at least secondary education (senior high school or equivalent). Data were analyzed using multiple linear regression with the ordinary least squares (OLS) method. The results indicate that the unemployment rate has a positive and statistically significant effect on poverty in Jambi City. Meanwhile, the education variable shows a positive but statistically insignificant effect on poverty. These findings suggest that unemployment is a dominant factor influencing urban poverty, whereas improvements in education alone have not been sufficient to reduce poverty without adequate job creation. The study highlights the importance of integrating education policies with employment-oriented economic development strategies. The results are expected to provide empirical evidence to support local governments in formulating more effective and integrated poverty alleviation policies at the urban level.  

The development of social media as part of digital technology has significantly transformed patterns of social interaction among adolescents in Indonesia. Social media no longer functions solely as a medium for communication and self-expression, but also as a social space that influences behavioral formation, including deviant and criminal behavior. This study aims to analyze the influence of social media on juvenile criminal behavior from a criminological perspective, with particular attention to social learning processes and the weakening of social control in digital environments. This research employs a qualitative method using a literature study approach by examining scientific journals, official reports, and statistical data related to social media use and adolescent behavior. The findings indicate that high intensity of social media use, exposure to negative content, and the normalization of aggressive behavior in digital spaces contribute to increased vulnerability of adolescents to criminal behaviors such as cyberbullying, online aggression, and other forms of deviance. Within the framework of Social Learning Theory, social media serves as a medium for behavioral learning through mechanisms of observation, imitation, and social reinforcement, while Social Control Theory highlights how weak supervision by families and educational institutions amplifies the risk of deviant behavior. The implications of this study emphasize the importance of preventive, non-penal approaches through strengthening social control, improving digital literacy, and enhancing the active role of families and schools to minimize the risk of juvenile criminal behavior in the digital era.

The growth of the digital era has a significant impact on Christian Religious Education (CRE), requiring a curriculum transformation to integrate Christian family values into academic learning. This study uses a descriptive qualitative approach with an exploratory case study design to analyze the integration of Christian family values such as love, open communication, and spiritual discipline—into the CRE curriculum. The results indicate that the integration of these values is effective in shaping students' Christlike character, encompassing cognitive, affective, and spiritual dimensions. Furthermore, technology-based learning becomes more meaningful when Christian family values are applied in the learning process. The study concludes that a curriculum model integrating these values can produce educators who are not only theologically competent but also Christlike in character, adaptable to digital developments, and responsive to the challenges of the times. This will strengthen the holistic faith formation in higher education, creating a generation that not only has a deep understanding of Christ's teachings but is also prepared to face the dynamics of life in the ever-evolving digital era.

The post-truth era and the dominance of social media pose significant challenges to public theological discussion practices, making the Christian community vulnerable to the spread of misinformation. This study aims to develop and test a digital literacy model for Christian educators to optimize social media as a space for healthy and critical dialogue. Using a mixed-method sequential explanatory approach, the study shows a significant improvement in information verification capacity and algorithmic awareness after the intervention. Qualitative findings reveal a paradox between emotional engagement and critical awareness, which was successfully addressed through the internalization of Christian communication ethics. The integrated model, which combines technical skills, public theology, and ethics, proves effective in transforming educators from passive consumers to active change agents in the digital space. Thus, educators can ethically and responsibly moderate theological discourse, making a significant contribution to creating a more thoughtful and open digital space for deeper and more meaningful theological dialogue. This research has implications for the development of digital literacy curricula in Christian education and serves as an initial step toward shaping a generation of educators who are critical and intelligent in facing the digital challenges of the future.

The rapid development of digital technology in the past decade has transformed Christian Religious Education (PAK) through synchronous–asynchronous models, Learning Management Systems (LMS), and blended learning, thereby expanding access and enriching both cognitive and spiritual learning experiences. However, this digital shift also introduces new risks related to child protection in online environments. National regulations mandate schools and higher education institutions, including PAK, to embed safeguarding principles into digital learning practices. Recent literature identifies three main research streams: the effectiveness of technology-enhanced learning, Christian ethics and digital spirituality, and faith-based digital literacy. Nonetheless, three research gaps remain: (1) limited integration of legal norms into technology-driven pedagogy, (2) absence of a safeguarding-by-design framework tailored for PAK, and (3) insufficient evaluation instruments to measure child protection outcomes in digital learning environments. This study aims to: (a) analyze the juridical implications of child protection regulations for the design, implementation, and evaluation of technology-based PAK strategies, (b) develop a “child-safe technology-based PAK framework” that integrates theological-pedagogical formation with regulatory compliance. The scientific contribution of this study lies in offering a PAK strategy that is not only pedagogically effective but also legally compliant, ethically grounded, and pastorally responsive thereby fostering a safe, inclusive, and child- centered learning ecosystem in the digital era.

This study aims to analyze contextual discipleship as a strategy for Christian education in a multicultural society. The study uses a mixed-methods approach with a convergent design to obtain a comprehensive understanding of the effectiveness of discipleship in shaping the character and spirituality of students. Quantitative data were collected through surveys, while qualitative data were gathered through in-depth interviews and focus group discussions. The results show that contextual discipleship plays a significant role in strengthening faith understanding, fostering tolerance, encouraging social involvement, and shaping students to be more responsive to the challenges of technological development and digital culture. Contextual discipleship proves to be effective when implemented consistently, based on mentoring relationships, and capable of translating Gospel values into the students' social context. This study concludes that contextual discipleship is a strategic approach that can present holistic, transformative, and relevant Christian education amidst diversity. Contextual discipleship allows Christian education to have a greater impact in shaping character that aligns with the demands of the times and contextualizing faith values in everyday life.

Indonesia, as the largest archipelagic state in the world, lies on international trade and transportation routes and possesses abundant natural resources. This strategic position creates both opportunities and challenges, particularly in the maritime domain, which requires the Indonesian Navy’s significant contribution in force deployment planning to counter future threats and disruptions. The evolving strategic environment necessitates specific policies and strategies for the Navy to enhance its strength in safeguarding sovereignty, territorial integrity, and national security. This development is pursued through the establishment of the Minimum Essential Force (MEF), a fundamental standard that defines the minimum level of naval capability required to effectively execute missions and functions. This study employs a qualitative descriptive method, using primary data from expert and user interviews as well as secondary data from observation and documentation, to analyze the selection of helicopter escorts utilized by the Indonesian Navy.

This study aims to analyze the role of innovation in enhancing the competitiveness of Micro, Small, and Medium Enterprises (MSMEs) in Medan City. The research employs a qualitative approach through direct interviews with several MSME owners from various business sectors. The results reveal that innovation plays a significant role in strengthening business competitiveness through product development, digital marketing strategies, and improvements in production processes. Product innovation among MSMEs includes changes in design, quality enhancement, and product diversification based on market demand. Meanwhile, marketing innovation is achieved through the utilization of social media and digital platforms to expand market reach and improve customer engagement. However, MSME actors still face challenges such as limited capital, low digital literacy, and lack of access to training and mentorship. Therefore, collaboration between business actors, government, and supporting institutions is essential to build a sustainable innovation ecosystem that strengthens the competitiveness of MSMEs in the digital era.

Reading literacy in early childhood is an important foundation for children's cognitive, language, and social development in subsequent educational stages. Literacy in early childhood can begin through letter recognition, fostering interest in printed materials, enriching vocabulary, and developing oral communication skills. At this stage, the initial skill that needs to be developed is the introduction of written language through reading activities tailored to the child's developmental characteristics. However, early childhood's ability to understand reading literacy shows significant differences, both in terms of interest, ability, and environmental support. This condition indicates that reading literacy understanding in early childhood is not evenly distributed. Therefore, this community service activity aims to provide reading literacy education to early childhood through a fun, interactive, and contextual approach. The activity methods include reading assistance, the use of visual media, and the active involvement of educators and parents. The results of the activity show an increase in reading interest, letter recognition skills, and children's positive responses to literacy activities. This activity is expected to be a sustainable effort to support the strengthening of reading literacy in early childhood education.

Language barriers represent one of the most significant obstacles to educational equity and access worldwide. This study investigates the application of Natural Language Processing (NLP) technologies in multilingual educational contexts to facilitate cross-linguistic learning and improve educational outcomes for linguistically diverse student populations. We implemented and evaluated a comprehensive NLP-powered multilingual learning platform across 47 educational institutions in 12 countries, serving 8,450 students speaking 23 different languages. Our experimental framework integrated machine translation, speech recognition, multilingual content generation, and adaptive language learning algorithms. Results demonstrate that NLP-enhanced multilingual education improved student comprehension by 43.6% (p<0.001), increased participation rates by 67.8%, and reduced achievement gaps between native and non-native speakers by 52.4%. Students using NLP-assisted learning tools achieved test scores averaging 78.3% compared to 54.7% for control groups. However, challenges persist regarding cultural context preservation, idiomatic expression handling, and equitable performance across language families. This research provides evidence that NLP technologies can effectively democratize education across linguistic boundaries while identifying critical areas requiring continued development.
