Cattle farming plays a strategic role in rural economic development by generating employment, supplementary household income, and contributing to food and nutritional security. However, in Indonesia, most smallholder cattle enterprises remain traditional and small-scale, leading farmers to treat livestock farming primarily as a secondary livelihood. While previous studies have largely focused on technical adoption and production performance, limited attention has been given to farmers’ psychological interest as a foundation for sustaining livestock enterprises. Therefore, this study aims to analyze the level of community interest in cattle farming and examine the influence of farmers’ characteristics (age, education level, herd size, number of family dependents, farming experience, and primary income) on such interest. A quantitative survey was conducted involving 34 cattle farmers in Taji Village, Jabung District, Malang Regency, selected using total sampling. Data were collected through structured questionnaires and analyzed using multiple linear regression. The findings reveal that community interest in cattle farming is generally high, as reflected in emotional (3.93), cognitive (3.81), and conative (3.74) dimensions measured on a four-point Likert scale. Regression results indicate that age has a significant positive effect (p = 0.022), whereas farming experience has a significant negative effect (p = 0.025) on interest levels. Other variables show no statistically significant influence. These findings highlight that psychological engagement in cattle farming is shaped more by demographic and experiential factors than by formal education or income level. The study contributes to the literature by positioning interest as a psychological determinant of livestock sustainability. Policy implications emphasize the urgency of risk-mitigation extension programs to address farmer burnout, incentivized intergenerational knowledge transfer, and cooperative-based institutional support to ensure smallholder livestock sustainability.

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 examines students’ interest in participating in the Al-Kautsar Tahfidz Dormitory Program at MAN 1 Baubau and identifies the factors influencing their participation. The study also seeks to provide a deeper understanding of how both internal and external conditions shape students’ willingness to engage in the program. Using a qualitative descriptive approach, data were collected through semi-structured interviews with dormitory supervisors, participating students, and non-participating students. Additional supporting information was also gathered through informal discussions and observation in the dormitory environment to strengthen the data validity. Data were analyzed through data reduction, data presentation, and conclusion drawing in an iterative process to ensure accurate interpretation. The findings indicate that students’ interest is shaped by internal factors, such as religious motivation, the desire to memorize the Qur’an, and self-improvement, as well as external factors, including parental support, peer influence, program socialization, and the religious dormitory environment. Conversely, low interest is associated with limited family support, low self-confidence in Qur’anic literacy, competing activities outside school, and perceptions of a demanding dormitory schedule. Overall, the program contributes positively to students’ religious character, discipline, and Qur’anic memorization skills, although variations in student interest remain evident depending on their personal and environmental conditions.

A bustier plays a crucial role in supporting the body, enhancing its shape, and enhancing aesthetics, especially when worn with a kebaya or evening gown. This study aims to analyze the results of bustier production using three different types of boning, such as needle-inserted boning, sewn-in boning, and steel boning, to determine the most optimal type of boning. The method used is Research and Development (R&D), encompassing data collection, product design, validation, testing, and product revision. This study found that the bustier with inserted boning achieved fairly good results with an average score of 3.00, which equates to 75.00% and falls into the “acceptable” category, while the bustier with sewn-in boning demonstrated the most optimal results. Based on validation testing by two expert validators, this product received an average score of 3.64 out of a total of 4, with a 90.91% acceptability rate, which falls into the “highly acceptable” category. The bustier with steel boning received an average score of 2.82, or 70.45%, which also falls into the “acceptable” category. Steel boning is not yet widely available, so its availability should be confirmed before production begins. Installing both sewn boning and steel boning requires precision. Therefore, it is recommended that you first practice structural sewing techniques.

Indonesia is an archipelagic country that has a diversity of ethnic groups as well as a rich heritage of arts and culture. One form of art found is weaving with clove flower motifs. The purpose of this study is “The Application of Clove Flower Motif Weaving Technique on Ready to Wear.” The main material used is shoelaces, as a weaving material that is easy to shape and unique. The method applied is Research and Development (R&D), which includes: identifying potential and problems, data collection through literature study, observation, documentation, product design, design validation, to the process of making and evaluating the final product. The results of the study show that the clove flower motif weaving technique can be well applied to ready to wear, especially on the vest and pants parts, producing a modern fashion. Applying this technique requires high precision, especially in the process of arranging the weaving pattern and integrating it with the main material. This study is expected to serve as a reference in developing innovative designs. The conclusion of this research is that the weaving technique gives a unique and aesthetic impression on ready to wear. The suggestion for making woven products applied to ready to wear is that during the process of ironing glue on the weave, the heat should not be too high because the shoelace material is easily burned, and the ends of the weave should be burned to prevent fraying.

Due to its effect on the caliber of generations to come, iron deficiency anemia in teenage females is one of Indonesia's most pressing reproductive health concerns. Adolescents' awareness to autonomously adopt preventative actions is shaped mostly by their knowledge. The purpose of this research is to determine whether there is a correlation between the prevalence of anemia among teenage females in Boyolali Regency and their degree of education. Using a cross-sectional design, this study employs quantitative correlational analytic methods. An accidental sampling approach was used to obtain a sample size of 80 respondents from the population of seventh grade female pupils. A digital POCT device was utilized to quantify the incidence of anemia variables based on hemoglobin (Hb) levels, while a structured questionnaire instrument was employed to gather data for knowledge variables. The Chi-Square test was used to assess the bivariate data analysis. According to the univariate analysis, 62.5% of the participants (50 respondents) had a decent level of knowledge, and 73.8% of the participants (59 respondents) did not suffer from anemia (Hb > 12 g/dL). With a p-value of 0.000 (p < 0.05), the results of the bivariate test were generated. Anemia is more common among female students at MTs Al Ihsan Doglo who have a higher degree of expertise, according to this study. School districts should keep an eye on students' iron pill use and improve their nutrition education programs.

This study explores how Generation Z in Indonesia produces and spreads narratives of micro-interfaith harmony through the TikTok platform. Amid growing social polarization in digital spaces, casual and personal tolerance content created by Gen Z offers a new approach to building social cohesion. Using a qualitative netnography method, this research observes 20 viral videos with over 10,000 views during the 2024-2025 Ramadan period, including the War Takjil trend and the #LoginLintasIman campaign, as forms of affective digital citizenship. The findings reveal that TikTok’s algorithmic logic, driven by emotional engagement, allows grassroots narratives of tolerance to reach broad audiences organically. Within this ecosystem, values of pluralism and solidarity are not shaped by formal institutions but emerge from the participatory dynamics and digital habitus of Gen Z. This study concludes that a new form of digital interfaith citizenship is emerging, termed algorithmic harmony, where tolerance is fostered through affective interactions, viral distribution, and the everyday media practices of youth. The findings provide new insights for media studies, diversity education, and digital tolerance discourse.

This article theologically analyzes the role of the Holy Spirit in the lives of believers through a study of the doctrine of pneumatology, traced from the testimony of Scripture to its impact on the practice of Christian faith. The purpose of this study is to explain how the work of the Holy Spirit is understood not merely as a theological concept, but also as a spiritual reality that shapes the identity, character, and dynamics of believers’ service. The method employed is qualitative research with a library research approach, involving the analysis of relevant theological and biblical sources to construct a conceptual framework concerning the work of the Holy Spirit in guidance, conviction, the sealing of salvation, spiritual transformation, and empowerment in ministry. This research is necessary because there remains a limited understanding of pneumatology that tends to be doctrinal and disconnected from concrete faith experiences. The findings of this study indicate that the presence of the Holy Spirit plays a vital role in leading believers into truth, forming Christian character, strengthening their identity as children of God, and empowering them to serve effectively within the community. Therefore, pneumatology holds significant practical relevance in fostering a dynamic, reflective, and transformative life of faith in the contemporary Christian context.

Concrete volume calculation is a crucial factor in preventing cost overruns when preparing the Budget Plan (RAB) for construction projects. In arch bridge projects, the complex structural geometry often makes conventional volume calculation methods complicated and prone to errors, particularly due to the geometric complexity of the arch beams. This study aims to analyze the comparison of concrete volume calculation results between the conventional method and the Building Information Modeling (BIM) method using Autodesk Revit in terms of cost-effectiveness. The case study was conducted on the Short Span II Pulau Balang Bridge Duplication Project in the Nusantara Capital City (IKN), Penajam Paser Utara Regency, East Kalimantan. The research objects include substructures (bore piles, pile caps, abutments, piers, and wing walls) and superstructures in the form of arch beams. The research method employs a quantitative approach by calculating concrete volumes conventionally using AutoCAD and Microsoft Excel, as well as calculating with BIM Autodesk Revit through three-dimensional modeling and Quantity Take-Off (QTO) exports. The results indicate that the BIM Autodesk Revit method generates a larger concrete volume compared to the conventional method, resulting in a higher total cost based on the BIM volume. The total cost for the conventional method amounted to IDR 142,613,245,996.12, while the BIM Autodesk Revit method amounted to IDR 143,127,208,186.60. These differences are influenced by the level of calculation detail, the simplification of shapes in the conventional method, and the precision of modeling in Autodesk Revit.

Batik motif classification has attracted growing attention in visual computing due to its role in cultural heritage preservation, textile informatics, museum documentation, and automated cataloging. Although many studies report high classification accuracy, robustness under real-world acquisition conditions remains insufficiently understood. Batik images are frequently affected by illumination variation, blur, folds, watermark overlays, wearable deformation, scale inconsistency, and background clutter, creating challenges that extend beyond conventional image-noise assumptions. Existing studies largely focus on improving classification performance, while the interactions among acquisition variability, feature representation, evaluation practice, and deployment constraints remain fragmented. This systematic literature review addresses this gap by synthesizing batik classification research through a robustness-aware perspective. Using query expansion, backward and forward citation chaining, relevance screening, and thematic coding, 116 candidate records were identified, resulting in 50 highly relevant studies for detailed analysis. The review reveals that robustness is shaped less by denoising alone than by the combined effects of acquisition conditions, representation design, evaluation realism, and deployment context. Handcrafted descriptors remain competitive for small datasets and structured motifs due to their data efficiency and interpretability, whereas deep learning models achieve the highest reported accuracy when supported by sufficient data diversity and realistic augmentation. Hybrid representations emerge as the most consistently balanced approach, combining local texture stability with higher-level abstraction across heterogeneous acquisition settings. The review further identifies recurring robustness failure patterns, including background dependency, illumination instability, motif-scale inconsistency, wearable deformation, and source-shift vulnerability. Based on these findings, a robustness-oriented research agenda is proposed, emphasizing cross-acquisition evaluation, representation-stability analysis, batik-specific robustness benchmarks, acquisition-aware augmentation, and deployable lightweight or hybrid architectures. The study contributes a domain-specific synthesis that reframes batik motif classification from an accuracy-centric task toward a robustness-aware visual recognition problem.

Postharvest handling of leafy vegetables, such as kale (Brassica oleracea var. acephala), is crucial for maintaining product quality and market value. This study aims to review the application of sorting and grading processes in improving the quality of horticultural products. The method used is a literature review of scientific journals and relevant references related to postharvest handling of vegetables. The findings indicate that sorting functions to separate damaged and unmarketable products based on physical condition, while grading classifies products into quality categories based on size, shape, and visual appearance. These processes contribute to reducing postharvest losses, improving product uniformity, and increasing market value. Furthermore, proper sorting and grading support quality control and enhance efficiency in distribution and marketing systems. Therefore, sorting and grading are essential components of postharvest management to ensure product quality and market competitiveness.

In the planning of removable partial dentures (RPD), design is a crucial factor that must be tailored to each patient’s clinical condition, while one of the main challenges in RPD design is anatomical variation in the oral cavity such as torus palatinus, which may affect retention, stability, and patient comfort. This report aims to discuss the design considerations of acrylic resin RPD in patients with torus palatinus, particularly in determining optimal design modifications. A 42-year-old female patient presented with complaints of difficulty chewing due to the loss of several teeth in both the maxilla and mandible. Intraoral examination revealed missing teeth 15, 11, and 25, with healthy mucosal and periodontal conditions, and a nodular torus palatinus measuring approximately 2.5 × 2 cm was identified along the midline of the palate. RPD design planning in this case requires an individualized approach, particularly in the selection of the major connector and base adaptation to avoid pressure on the torus area, and design modifications were implemented to improve load distribution and patient comfort. The use of a U-shaped major connector with relief over the torus area effectively avoids direct contact, thereby enhancing comfort, preventing mucosal irritation, and supporting masticatory function.

This study examines sarcastic implicatures in the 2024 United States presidential debate between Joe Biden and Donald Trump, with a particular focus on Donald Trump’s utterances. The study aims to identify the forms and types of sarcastic implicatures employed in political discourse during the debate. A qualitative descriptive method with a pragmatic approach was used to analyze how implied meanings are constructed and interpreted within the context of political communication. The data consisted of debate transcripts and video recordings broadcast by CNN, selected based on utterances containing elements of sarcasm. Data analysis was conducted through four stages: identification, classification, coding, and interpretation. The findings reveal that sarcastic implicatures are realized in two main forms, namely indirect non-literal utterances and direct non-literal utterances. In addition, several types of sarcastic implicatures were identified, including undermining, mockery, insult, criticism, and threat. The most dominant type was undermining, which was used to weaken the image and credibility of political opponents. These findings indicate that sarcastic implicatures function as an effective rhetorical strategy in political communication to influence public opinion, shape audience perceptions, and strengthen the speaker’s political position in televised political debates.

Churches and Christian institutions frequently face the challenge of congregations whose understanding of ministry remains confined to the spiritual dimension alone, while the holistic ministry mandate calls for active engagement across social, educational, and economic spheres. This study examines two primary objectives: first, how Christian Religious Education (CRE) shapes congregational understanding of holistic church ministry; and second, how CRE equips congregants with the concrete capacity to serve comprehensively. A qualitative approach with a case study design was employed at Yayasan Sola Gratia Medan. Data were gathered through in-depth interviews with seven informants comprising foundation leaders, program coordinators, active church members, volunteers, and beneficiaries. Analysis followed a thematic framework encompassing data reduction, display, and conclusion drawing. Findings reveal that: (1) consistent CRE implementation at Yayasan Sola Gratia has successfully shifted the congregational ministry paradigm from exclusively spiritual to holistically transformative; and (2) congregants who have internalized CRE values demonstrate more structured ministry capacity, stronger theological motivation, and significant cross-dimensional engagement. This research contributes a contextual CRE model relevant for church-based institutions operating in multidimensional urban environments.

The presence of Generation Z, who grew up entirely in the digital era, has triggered a fundamental transformation in Muslim religious practices, where social media has replaced conventional religious institutions as the primary source of religious information. This condition creates a paradox: Gen Z has become a generation that is highly religious online, yet is often disconnected from physical communities and traditional religious authorities. This study aims to analyze the character of Muslim Gen Z religiosity, identify its forming factors, and examine the impact of the digital era on their religiosity. This study employed a descriptive qualitative approach using a library research method. The findings indicate that Muslim Gen Z religiosity is characterized by personalization, flexibility, and digital spirituality, strongly influenced by social media. These characteristics are shaped by massive digital technology accessibility, the effectiveness of contextual Islamic preaching on platforms such as TikTok, as well as spiritual needs and social pressure from the digital environment. The digital era brings positive impacts in the form of increased accessibility and religious literacy, but also negative impacts including shallow religious understanding, vulnerability to information bias, and potential exposure to extreme ideologies. This study implies the importance of an integrated digital religious literacy strategy through critical thinking-based Islamic Religious Education curriculum reform, enhancement of educators' digital capacity, and cross-sector collaboration to strengthen Gen Z's moderate and reflective religious understanding.

The acceleration of digitalization in recent years has shaped a new socio-economic landscape in Indonesia. Access to app-based financial services and online entertainment has increased rapidly, but at the same time, illegal online lending and digital gambling, targeting adolescents, have flourished. This paper explores a Community Service intervention model that combines preventative digital literacy and artificial intelligence (AI) optimization within the La Tansa Islamic Boarding School in Palembang. The research was conducted using a qualitative approach with participant observation, in-depth interviews, focus group discussions, and written reflection analysis. Findings indicate that strengthening digital literacy based on critical awareness not only improves risk understanding but also deepens self-control integrated with religious values. AI training for educators also encourages changes in learning practices to be more adaptive and reflective of the dynamics of the digital era. This model offers a digital resilience approach that can be replicated in other educational institutions with similar characteristics.

Golf participation has increasingly become a lifestyle-oriented recreational activity that combines physical exercise, social interaction, and personal identity. However, participation decisions are not only shaped by individual interest, but also by demographic readiness, psychographic orientation, digital promotional exposure, and psychological commitment to the sport. This study aims to examine the influence of demographic factors, psychographic factors, and digital promotion on golf participation decisions in Bandar Lampung, with sport commitment as a mediating variable. A quantitative survey approach was employed using purposive sampling. Data were collected from 287 golf participants through a structured questionnaire measured with a five-point Likert scale. The data were analyzed using multiple linear regression and Sobel mediation testing. The findings show that demographic factors, psychographic factors, digital promotion, and sport commitment have positive and significant effects on golf participation decisions. Sport commitment was found to be the strongest predictor and significantly mediated the relationship between demographic factors, psychographic factors, digital promotion, and golf participation decisions. These results indicate that golf participation is influenced not only by access, lifestyle, and digital promotion, but also by the level of commitment developed by participants. This study contributes to sport marketing literature by integrating individual, psychological, and digital factors into one empirical model of golf participation behavior.

The rapid development of digital technology has significantly transformed the ways in which faith is experienced, particularly in the lives of adolescents. From the perspectives of digital religion and mediatization of religion, digital space is no longer merely a medium, but has become a cultural arena that actively shapes religious practices and meanings. The study aims to analyze these dynamics, especially within the context of Generation Alpha, by examining the opportunities and challenges that emerge in the lived experience of faith in the digital age. The findings indicate that digital environments offer creative, participatory, and contextual opportunities for evangelization, enabling young people to engage actively in constructing their religious experiences. However, this dynamic is inherently ambivalent, as it also risks reducing the meaning of faith to symbolic, instant, and less sacramentally grounded experiences, detached from the communal life of the Church. Furthermore, the formation of religious identity in digital spaces tends to be fluid and performative, potentially leading to superficial relationships and fragmented identities. Therefore, technologically mediated religious experience should be understood as a bridge, rather than a substitute, for authentic faith encounters. The Church is thus called to adopt adaptive and reflective pastoral approaches, positioning media as a means of fostering communio without obscuring the essence of faith. An integrative approach through the synergy of Church, family, and educational institutions is essential to balance digital literacy and spiritual depth, ensuring that adolescent faith continues to grow reflectively and remains rooted in real-life experience.

The article entitled “Gender Construction and Representation of Social Actors in the Drama Lutung Kasarung: A Critical Discourse Analysis by Theo van Leeuwen” aims to describe the representation of gender-based social actors through inclusion and exclusion strategies and to reveal the construction of gender ideology built in the drama text. This study uses a qualitative approach with a descriptive-analytical design. The research data source is the drama text Lutung Kasarung, while the analysis unit includes dialogue, narrative, and the depiction of characters who represent gender-based social actors. Data collection techniques are carried out through documentation by reading, identifying, and grouping data according to Theo van Leeuwen's analysis categories. The results of the study show that the inclusion strategy is more dominantly used to present male characters as strong, rational figures, and have authority in determining the course of the story. In contrast, female characters are represented in two patterns, namely the ideal passive woman and the dominant woman who is constructed negatively. In addition, the exclusion strategy is used to obscure the role of women in decision-making, thereby reinforcing gender marginalization. This study concludes that the drama Lutung Kasarung represents patriarchal ideology through discourse practices that shape power relations between men and women.

Sign language recognition is one of the areas of image recognition and image processing technology that is developing rapidly in human-computer interaction. This technology really helps the deaf and speech impaired in communicating with non-disabled people. This research aims to examine the optimization of an object tracking system in sign language using the Gaussian Mixture Model (GMM) and Kalman Filter by including the Region of Interest (ROI). The proposed system consists of three main components, namely hand detection, object extraction, and classification. Hand detection is done using the Kalman Filter to track hand movements accurately. Next, Region of Interest (ROI) features, such as shape, direction and movement features, are extracted from the detected part of the hand. These features are fed into a Gaussian Mixture Model (GMM) classifier, which can recognize sign language based on the extracted features. With the combination of GMM and Kalman Filter in this research, it can increase accuracy in object tracking, reduce interference from the background, and ensure the tracking focus remains on important objects. The dataset used is in the form os SIBI alphabet symbols, namely A-Z with the amount of data for each class, namely 620 images. Based on the research result, model testing using GMM, Kalman Filter and ROI produces higher accuracy of 99%, while model testing using GMM and ROI produces accuracy of 90%.
