This study aimed to determine the effect of different levels of beef liver addition on the nutritional, physicochemical, and color characteristics of chicken patties. Beef liver, an underutilized animal by-product with high nutritional value, was incorporated at different levels (0%, 20%, 40%, and 60%) into chicken patty formulations. The experiment was conducted using a Completely Randomized Design with four treatments and five replications. The collected data were analyzed using analysis of variance (ANOVA) and followed by Duncan’s Multiple Range Test (DMRT). The results showed that the addition of beef liver had no significant effect (P>0.05) on protein content, water activity (aw), and b* values, but had a highly significant effect (P<0.01) on moisture content, fat content, cooking loss, texture, and color characteristics (L* and a*). Increasing beef liver levels improved the nutritional profile and modified the physical and visual characteristics of the patties. These findings demonstrate the potential of beef liver as a value-added functional ingredient for developing nutritious chicken patties while promoting the sustainable utilization of underutilized livestock by-products.

This study aims to analyze the inner conflict experienced by the female protagonist, Alina Suhita, in the novel Hati Suhita by Khilma Anis using Karen Horney’s psychological perspective. The study is motivated by the complexity of the psychological struggles faced by the main character in dealing with marital pressures, family expectations, and socio-cultural demands within a pesantren environment. This research employed a descriptive qualitative approach using content analysis. The data source was the novel Hati Suhita by Khilma Anis, while the research data consisted of textual excerpts depicting the protagonist’s inner conflicts. Data were collected through reading and note-taking techniques and subsequently analyzed based on Karen Horney’s theory of neurotic tendencies. The findings reveal that Suhita’s inner conflict is influenced by marital pressures, family demands, social expectations, as well as cultural and religious values that shape her personality. These conflicts are manifested through three neurotic tendencies: moving toward people, moving against people, and moving away from people. The tendency of moving toward people is reflected in her obedience, self-sacrifice, and need for acceptance. The tendency of moving against people appears in her efforts to maintain self-respect, assertiveness, and courage in confronting pressure. Meanwhile, the tendency of moving away from people is shown through emotional withdrawal, solitude, and the pursuit of inner peace. The findings indicate that the protagonist’s inner conflict is dynamic and functions as a form of psychological adjustment to basic anxiety and socio-cultural pressures throughout the narrative.

This study aims to develop a strategy for developing praise and worship services through a deeper biblical theology of Psalm 150, as a fundamental solution for congregational growth at YHS Eka Sinta Church in Kapuas Regency. The main premise of this study is based on the crucial disconnect between contemporary church music practices, which tend to be performative, and the essence of the doxology authoritatively contained in the text Scripture. By integrating descriptive qualitative methods and an exegetical biblical theology approach, this study explores the imperative meaning and poetic structure of Psalm 150 and then engages them in intercultural dialogue with the sociocultural context of local churches in Kalimantan. The results reveal that the biblical theology Psalm 150 emphasizes the totality of instrumental use and the universality of the subject of praise as an absolute reflection of God's sovereignty and might. Field findings indicate that the effectiveness of music services is often hampered by technical limitations and theological shallowness of liturgical ministers. This study concludes that healthy congregational growth, both in terms of spiritual quality and quantity, is rooted in the extent to which the church able to actualize biblical theological values ​​in expressions of praise that are relevant and resonate with the cultural background and local identity of its congregation. The resulting strategy offers a holistic ministry model, in which church music returns to its essential function as an instrument of faith transformation and a means of growing the Kingdom of God, adaptively yet faithful to the biblical text.

Haul Guru Sekumpul is one of the biggest religious traditions in Indonesia that brings together millions of participants from various regions to commemorate KH. Muhammad Zaini Abdul Ghani, better known as Guru Sekumpul. This activity not only serves as a religious commemoration, but also reflects the value of togetherness, solidarity, and deep spirituality. This research aims to reinforce the argument that in fact the feedback process between group involvement and emotional reactions strengthens solidarity, both in mechanical and organic contexts, thus creating deeper social bonds. Thus, mechanical and organic solidarity are not separate but interrelated. Through a qualitative approach, this research analyzes how mechanical and organic solidarity interact with each other in the context of this activity. The results show that mechanical solidarity, characterized by shared values and beliefs, serves as the foundation for a more complex organic solidarity, where individuals with different roles depend on each other. The findings also serve as a critique of Émile Durkheim's theory of solidarity. In addition, the use of social media and traditional media plays an important role in disseminating information and organizing activities, creating a sense of community among congregants. This is also a new additional factor that is in line with the changing times but was previously undeveloped during Émile Durkheim's time. Thus, Haul Guru Sekumpul is not only a religious event, but also a symbol of collective power that binds people in a common goal, creating a harmonious and respectful community.

This research aims to analyze the gap between the profit-sharing principle as the normative foundation of Islamic economics and the risk management practices applied in sharia cooperatives, considering the ongoing inconsistencies in the implementation of the risk-sharing principle. The research method employs a qualitative approach thru literature study with thematic and comparative analysis techniques on relevant academic literature. The results and discussion indicate that sharia cooperatives tend to adopt a conventional risk management paradigm oriented toward institutional stability, thereby triggering the dominance of non-profit-sharing contracts and the shift of the concept of risk sharing to risk shifting in operational practices. The gap is influenced by structural factors, including limitations in managerial capacity, information asymmetry, potential moral hazard, and pressures of institutional sustainability. This study concludes that the risk management practices of sharia cooperatives do not fully reflect the principles of Islamic economics, thus necessitating a reconstruction of a more integrative and contextual risk management model. As a suggestion, sharia cooperatives need to develop a risk management framework based on risk sharing that is adaptive to operational risks without disregarding the values of justice and partnership as the main characteristics of Islamic economics.

This study aims to analyze the religious and spiritual symbols represented in the film Titip Surat untuk Tuhan through Roland Barthes’ semiotic approach, focusing on the three levels of meaning: denotation, connotation, and myth. The research employs a qualitative descriptive method using semiotic analysis based on document studies of selected scenes, dialogues, and visual elements portraying religious values, prayer, sacrifice, patience, hope, gratitude, and trust in God. The findings reveal that symbols such as the mosque, mukena, sarong, prayer mat, the Qur’an, prayer activities, the post office as a medium for sending letters to God, and the calligraphy of “Allah” and “Prophet Muhammad” on the walls function not only as literal signs but also convey profound religious and spiritual connotations. These symbols further develop into myths that reinforce religious norms and cultural beliefs accepted as natural within society. The film successfully constructs a subtle yet powerful representation of faith by portraying a Muslim family that upholds devotion, moral values, patience, compassion, and an enduring relationship with God. Overall, the film demonstrates how religious symbols effectively communicate spiritual messages while strengthening viewers’ understanding of Islamic values through visual and narrative storytelling.

Pressure sensitive labels (PSLs) made of polyethylene (PE) white are widely used in the packaging industry due to their flexibility, moisture resistance, and ease of application on various substrates. This study aimed to examine the effect of glossy and matte lamination on the tensile strength and color difference (ΔE) of PE white PSLs. An experimental method was employed, with tensile testing conducted using a universal testing machine (UTM) in accordance with ASTM standards and color measurement performed using a spectrodensitometer based on the CIE Lab system. The samples were divided into three treatment groups, namely no lamination, glossy lamination, and matte lamination, with ink coverage controlled at two design conditions, full ink and minim ink. The results indicated that lamination type significantly affected both the mechanical and visual characteristics of the labels. In the tensile strength test, the highest mean value was obtained by one treatment group, indicating superior resistance to tensile loading. In terms of color stability, higher ΔE values indicated greater color change and lower lightfastness, whereas lower ΔE values reflected better color retention. Overall, the findings show that the combination of lamination type and ink coverage influences the performance of PE white PSLs in both mechanical strength and color stability.

The Indonesian Archipelagic Sea Lane II (ALKI II) constitutes a strategic route stretching from the Sulawesi Sea to the Indian Ocean with trade values reaching USD 1.5 million daily and traversed by more than 36,773 vessels annually. The complexity of maritime security threats in this region has increasingly intensified following the relocation of the capital city to East Kalimantan, thereby demanding an effective decision support system to assist Indonesian Warship Commanders in making operational decisions that are rapid, accurate, and in accordance with applicable legal provisions. This research employs a qualitative approach through in-depth interviews with four maritime expert sources, with data analysis using NVivo 12 software. Analysis results identified maritime operational complexity and the urgent need for a comprehensive decision support system. These findings subsequently served as guidance in designing a Decision Support System (DSS) with a tab-based interface that integrates international legal frameworks such as UNCLOS 1982, Law No. 3/2025 on TNI, and related national regulations to generate structured action recommendations along with their legal foundations. Research findings demonstrate that the developed DSS successfully integrates operational, legal, and situational aspects to support decision-making that is rapid, accurate, and legally compliant. This system has proven to enhance the effectiveness of Indonesian Warship Commanders in addressing the complexity of maritime security (KAMLA) challenges in ALKI II through the provision of legally-based action recommendations from national and international frameworks accessible in realtime during operational situations.

Traditional wedding rituals constitute intangible cultural heritage rich in symbolic meaning, serving to strengthen social solidarity and transmit cultural values. The massive penetration of modernization and digitalization has created new pressures for the Bugis-Makassar community in maintaining this heritage. This study analyzes the transformation of Bugis-Makassar traditional wedding rituals in South Sulawesi within the digital era context, focusing on how the community negotiates their cultural identity between the forces of tradition and modernity. Using a critical ethnographic approach with a multiple case study design grounded in Bhabha's concept of the third space, the study involved 42 informants from three groups: young couples (digital generation, aged 22–35), parents/family (middle generation, 40–60), and customary elders (to panrita lopi/bissu, 65+) in Makassar City, Bone Regency, and Wajo Regency. Data were collected through in-depth interviews, participant observation in 12 wedding ceremonies, and social media content analysis. Results reveal three main transformation patterns: (1) digital spectacularization—rituals adapted for social media consumption; (2) reflective selectivity—young couples actively choosing which traditional elements to retain; and (3) procedural hybridization—the integration of customary procedures with contemporary elements. These transformations are colored by intergenerational contestation that generally ends in compromise between demands for customary completeness and the aesthetic preferences of the younger generation. The study concludes that this transformation is not merely a loss of tradition, but a creative form of identity negotiation in which the Bugis-Makassar community actively reconstructs the meaning of siri' (self-esteem/dignity) and pesse (solidarity) within the changed socio-cultural landscape. The findings imply the need for cultural preservation policies that understand change as inherent to living culture, and open avenues for longitudinal studies on the intergenerational transmission of cultural values.

This study aims to examine relevant and effective Christian Religious Education (CRE) learning methods in the digital era. The rapid development of information and communication technology has brought significant changes in education, including CRE instruction. The research method employed is a literature study with a descriptive-analytical approach to various academic sources and technology-based CRE learning practices. The results indicate that integrating digital media such as online learning platforms, Bible-based interactive applications, and social media creatively can enhance students' engagement and understanding of Christian faith values. Furthermore, the use of digital technology opens wider opportunities for contextual and meaningful faith formation across diverse learning environments. The study also identifies key challenges faced by CRE teachers, namely digital readiness, infrastructure limitations, and maintaining relational and spiritual dimensions in virtual learning environments. Teachers must therefore be equipped not only technologically but also theologically to navigate these complexities. The research concludes that the transformation of CRE methods in the digital era is not merely a technology adoption but a holistic theological integration of faith, technology, and pedagogy.

Lead (Pb²⁺) is a hazardous heavy metal commonly found in industrial wastewater and poses serious risks to human health and the environment due to its toxic and non-biodegradable nature. Therefore, an effective and environmentally friendly treatment method is required to reduce Pb²⁺ concentration in wastewater. This study aimed to evaluate the effect of pH and initial Pb²⁺ concentration on the adsorption capacity of ramie leaf (Boehmeria nivea) bioadsorbent activated with NaOH. The adsorption process was conducted using a batch system with pH variations of 4, 5, and 7 and initial Pb²⁺ concentrations of 20, 25, and 30 mg/L. The residual Pb²⁺ concentration was analyzed using Atomic Absorption Spectrophotometry (AAS), and the adsorption performance was evaluated based on removal efficiency and adsorption capacity (Qe). The results showed that pH and initial Pb²⁺ concentration significantly affected the adsorption performance. The optimum adsorption condition was obtained at pH 5, with a maximum removal efficiency of 99.20% and a total adsorption capacity of 18.56 mg/g. The increase in pH from 4 to 5 enhanced adsorption performance due to reduced competition between H⁺ and Pb²⁺ ions for active sites on the adsorbent surface. Increasing the initial Pb²⁺ concentration tended to increase adsorption capacity, although removal efficiency remained relatively stable due to the limited number of active adsorption sites. The Relative Standard Deviation (RSD) values ranged from 1.56% to 3.37%, indicating good precision and repeatability of the experimental data. These findings demonstrate that NaOH-activated ramie leaves have considerable potential as an effective, low-cost, and environmentally friendly bioadsorbent for Pb²⁺ removal from wastewater.
