Surabaya is one of the metropolitan cities in Indonesia with significant potential for the development of sports performance and the improvement of public health quality. The advancement of modern sports requires a sport science–based approach that integrates training, health, technology, and research aspects. However, the lack of integrated sport science facilities remains a major challenge. Therefore, proper site selection is a crucial factor in the design of a Sport Science Center. This study aims to formulate appropriate site selection criteria for the design of a Sport Science Center in Surabaya. The research method used is descriptive qualitative, employing literature studies, site observations, and comparative analysis of alternative sites based on predetermined criteria. The results indicate that the main site selection criteria include accessibility, proximity to supporting facilities, compliance with spatial planning regulations, environmental conditions, land area, and future development potential. Based on the analysis, the Middle East Ring Road (MERR) area in Surabaya is considered the most suitable location for the development of a Sport Science Center.

This study aims to analyze the spatial pattern of poverty in Gorontalo Province in 2024 using global and local spatial autocorrelation approaches. The data used are the percentages of the poor population in each regency/municipality, obtained from the BPS. The analyses include descriptive statistical analysis, the Moran's Index test for global spatial autocorrelation, and the Local Indicators of Spatial Association (LISA) for local autocorrelation. The results show that poverty in Gorontalo Province tends to be unevenly distributed and exhibits a significant spatial pattern. The Moran's Index indicates positive spatial autocorrelation, where areas with high poverty levels tend to be adjacent to other areas with similarly high poverty levels. The LISA results identify Bone Bolango Regency as a High-Low area, meaning it has a high poverty rate but is surrounded by areas with low poverty rates. These findings highlight the importance of spatial approaches in formulating more targeted poverty alleviation policies.

The Fréchet distribution is one of the commonly used Extreme Value Distributions (EVDs) in statistical modeling and heavy-tailed data analysis, where it plays an important role in describing product lifetimes as well as climatic and financial phenomena. The estimation of its two parameters, namely the shape parameter and the scale parameter, is traditionally based on the Maximum Likelihood Estimation (MLE) method. However, maximizing the likelihood function for this distribution involves numerical difficulties, which necessitates the use of numerical optimization methods. In this study, we propose the use of the Aquila Optimizer (AO), a recent metaheuristic algorithm inspired by the hunting behavior of eagles, as an efficient numerical tool for maximizing the likelihood function of the Fréchet distribution. The objective function was formulated as the negative log-likelihood function (-LogL), and the Aquila Optimizer was employed to obtain the optimal estimates of the distribution parameters. Several simulation experiments with different sample sizes were conducted to compare the performance of the proposed method with a conventional approach represented by the Nelder–Mead method, using the Mean Squared Error (MSE) criterion. The simulation results demonstrated that the Aquila Optimizer outperformed the Nelder–Mead algorithm in many cases, although the superiority was slight. The results also showed that both algorithms were consistent, as their MSE values decreased with increasing sample size. In addition, a practical application was carried out using real data, and the results of the survival function estimation indicated a good fit.

This community service project aims to accentuate inclusive values among the youth of Tanjung Dapura, Makassar City, to strengthen social cohesion in a heterogeneous urban environment. The implementation methods included team consolidation, material preparation, and strategic coordination with local government authorities. The core activities were conducted through participatory counseling and Focus Group Discussions (FGD) to independently analyze social exclusion challenges. The materials focused on the importance of respecting diversity and the strategic role of youth as inclusive agents of change. The results indicated a significant increase in participants' understanding of inclusion literacy and their ability to formulate creative solutions for local discrimination issues. Evaluation through observation and reflection confirmed a paradigm shift among the youth from passive tolerance toward active participation in embracing differences. This project concludes that the synergy between critical education and collaborative dialogue successfully transforms youth into resilient pillars of social harmony. The accentuation of these inclusive values is expected to become the foundation for a more just and sustainable coastal community in Makassar.

The economy of a country, including Indonesia, is a system that encompasses all production, distribution, and consumption activities occurring within the country. In the economy, problems often arise that can affect the welfare of society. The problem formulation in this study is: How is the regulation and supervision of both internal and external banks carried out to prevent customer personal data leakage in credit agreements? And how is the responsibility of BPR Karya Sari Sedana towards the leakage of customer debtor data? The research method used is empirical legal research. The conclusion in the study is the protection of customer data against personal data leakage by understanding the forms of supervision from both internal and external parties conducted by the banking institution and referring to the OJK regulations that have been established, in order to minimize the recurrence of similar incidents and allow the public to conduct transactions safely without worrying about their personal data. Leaked by irresponsible individuals. The responsibility carried out by the banking sector currently, namely the Financial Services Authority Regulation Number 22 of 2023 concerning Consumer and Community Protection in the Financial Services Sector, also regulates consumer protection in the financial services industry. Forms in policies related to regulations in the banking world ensure that the public does not worry about their personal data.

This study aims to evaluate the growth performance of KUB chickens fed with a combination of fermented agricultural waste, specifically Maggot BSF (Hermetia illucens) and Azolla microphylla. A total of 96 KUB chickens aged 30 days were used in a Completely Randomized Design (CRD) with four treatments and four replications. The treatments consisted of a basal diet substituted with the fermented waste combination at levels of 0% (P0), 5% (P1), 10% (P2), and 15% (P3). Parameters observed included feed consumption, body weight gain (BWG), and Feed Conversion Ratio (FCR). The results showed that increasing the level of waste substitution significantly affected feed consumption due to the bulky nature of the fiber, yet body weight gain remained stable across all treatments. The FCR values ranging from 3.21 to 3.25 indicated that the high-quality protein from Maggot BSF effectively compensated for the reduced feed intake. It is concluded that the substitution of fermented agricultural waste up to 15% (P3) is an optimal and efficient formulation to maintain the growth performance of KUB chickens.

Gillnet fisheries play an important role in supporting the local economy and the welfare of coastal communities. However, fishermen still face challenges related to unequal access to livelihood assets and high vulnerability to external factors such as seasonal changes, catch fluctuations, market pressures, and environmental conditions. This study aimed to analyze the level of vulnerability, identify livelihood assets, and formulate strategies for sustainable livelihood development among gillnet fishing communities. The study was conducted in Margasari and Muara Gading Mas Villages in September 2025 using a mixed-method approach, combining questionnaires, in-depth interviews, and field observations. Samples were selected through purposive sampling, and data were analyzed using descriptive quantitative and qualitative methods supported by a Likert scale. The results showed that fishermen’s vulnerability is relatively high (54.5%), affecting income stability. Social (81.4%) and natural (78.7%) assets are relatively strong, while human (38.6%), physic (48.3%), and financial (43.20%) assets remain relatively low. Limited education, lack of training, and restricted access to financial resources are the main constraints, leading to low adaptive capacity and limited livelihood diversification. Recommended strategies include improving human resource capacity, strengthening access to financial capital, and developing livelihood diversification based on local potential. These efforts are expected to enhance household economic resilience and support sustainable livelihoods among gillnet fishing communities.

This study analyzes law enforcement related to the application of the death penalty with a ten-year probation period as stipulated in the Criminal Code (KUHP). The results of the study show that the enforcement of the conditional death penalty is carried out in three stages, namely the formulation, application, and implementation stages. The formulation stage is reflected in the establishment of the death penalty as a special alternative and conditional punishment in Law Number 1 of 2023, the application stage is carried out through the application of norms by law enforcement officials, while the implementation stage relates to the execution of court decisions against convicts. The change in the construction of the death penalty from an absolute primary punishment to an alternative and special conditional punishment has fundamental legal implications for the criminal justice system in Indonesia, especially with the existence of discretion for judges and law enforcement officials to assess the possibility of changing the type of punishment based on the convicted person's remorse and efforts to reform themselves during the probation period.

The agricultural sector plays a strategic role in meeting food needs while maintaining environmental sustainability and community welfare. However, conventional farming practices that rely on chemical inputs have caused various problems, such as soil degradation, loss of biodiversity, and environmental pollution. This condition has encouraged the adoption of the Sustainable Agriculture concept, which emphasizes a balance between ecological, economic, and social aspects. Its successful implementation is strongly influenced by farmers’ perceptions as the main actors. This study aims to analyze rice farmers’ perceptions of the implementation of Sustainable Agriculture in swampy areas of Tebas District, Sambas Regency. The research was conducted from October to November 2025 using a survey method involving 95 farmers selected through the Slovin formula and proportional random sampling technique. Data were collected through observation, interviews, and Likert-scale questionnaires, and analyzed using descriptive analysis and binary logistic regression. The results show that farmers’ perceptions are generally positive, particularly regarding water management, variety selection, and cropping patterns. However, the use of organic fertilizers, environmentally friendly pest control, and post-harvest management are still considered difficult. Education level and non-farming occupations significantly influence farmers’ perceptions. Therefore, enhancing extension services, training, and support for business diversification is necessary to promote the adoption of Sustainable Agriculture.

Tegal possesses substantial capture fisheries potential, supported by the availability of adequate human resources and appropriate infrastructure. One of the most commonly utilized fishing gears at the Tegalsari Nusantara Fishing Port is the pocket seine net. This study was conducted to evaluate the environmental friendliness of pocket seine fishing gear operated by fishermen at the Tegalsari Nusantara Fishing Port and to analyze the composition of the catch produced by this gear. The research employed a survey method using a questionnaire instrument based on nine criteria for environmentally friendly fishing gear. The respondents in this study were fishermen operating pocket seine net, and the number of respondents was determined using the Slovin formula. Data were processed using descriptive analysis. Meanwhile, the catch composition data were analyzed using the comparative method. The results of the fishing gear friendliness assessment indicate that the pocket seine gear used by fishermen at the Tegalsari Nusantara Fishing Port falls within the environmentally friendly category, with an indicator score ranging from 19 to 27. The catch composition of pocket seine gear comprises 12 species, which are classified into main catch and bycatch. All captured species possess economic value; consequently, no catch is discarded.

With growing antimicrobial resistance becoming a major health concern, there is an urgent need to explore alternative treatment options. This study examined the efficacy of copper sulfate pentahydrate (CSP) against eight microorganisms commonly implicated in vaginal infections. We tested three Candida species (C. albicans, C. glabrata, and C. tropicalis) along with five bacterial species, including Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Gardnerella vaginalis, and Pseudomonas aeruginosa. The agar dilution test was performed at concentrations ranging from 0.0001M to 0.7M of CSP. We obtained an effect of CSP antimicrobial, which was concentration-dependent. Concentrations low ( ≤ 0.007M) did not influence growth significantly. We observed partial growth inhibition at medium concentrations (0.05-0.07M, equivalent to approximately 780 -1092 µg/ml) of the solution. The growth of bacteria and yeasts was fully inhibited at 0.05M and 0.07M, respectively. The dose required to kill the organisms (not merely inhibit their growth) was 0.25M (approximately 2014 µg/ml) across all microorganisms used, and we verified this by observing no growth when samples were inoculated into fresh media. These findings have indicated that CSP possesses good antimicrobial efficacy against typical vaginal pathogens at doses that may be applied in topical therapies. However, some additional research is required, especially the research that will investigate the toxicity on human cells and the production of suitable formulations to be used clinically.

The increasing demands of global trade, the risk of transboundary diseases, and the stringency of sanitary and phytosanitary (SPS) standards require a more integrated, transparent, and risk-based national quarantine system. The partial readiness of digital systems and traceability mechanisms has the potential to weaken Indonesia’s food security and export competitiveness toward the vision of Golden Indonesia 2045. This study aims to analyze the strategic role of the quarantine system in national development, identify institutional and technical root problems, and formulate the most concrete and feasible policy alternatives. The method used is policy analysis with a multi-criteria analysis (MCA) approach to compare several solution alternatives based on effectiveness, efficiency, technical aspects, and political feasibility. The results indicate that the digital transformation of the national quarantine system based on traceability and risk-based intelligence is the most superior policy option, as it can simultaneously address data fragmentation, improve service efficiency, and strengthen biosecurity surveillance. This study recommends the development of a Quarantine Super App, full implementation of e-certification, integration with the National Logistics Ecosystem and Customs, and the strengthening of an artificial intelligence-based risk profiling system. Gradual implementation accompanied by performance indicator-based evaluation is key to the success of the policy in enhancing national food security and export competitiveness.

This study analyzes the dynamics of "Early Marriage and Shattered School Hopes" regarding eroded psychological well-being and pawned adolescent ideals in Brebes Regency. Using a qualitative case study design, data were gathered via in-depth interviews, participatory observation, and document analysis from eight informants, processed using Miles and Huberman's interactive model. Findings reveal early marriage is not merely a social event but systemic trauma damaging psychological structures through three aspects: first, victims' psychological conditions marked by identity loss, prolonged anxiety, and "fatalistic resignation"; second, lost educational access due to interactions of "normative-cultural coercion," "institutional structural barriers," and "economic-domestic double burdens"; third, manifestations of buried ideals comprising "hindered academic grief," "identity cognitive conflict," and "internalized existential despair." The research proves education loss from early marriage destroys human potential, altering character, leaving spiritual voids, and perpetuating intergenerational poverty cycles, thus urgently demanding holistic interventions including psychosocial rehabilitation and alternative education pathways. This study's main contribution is introducing the "systemic trauma" concept that actively extinguishes adolescents' existential hopes, filling literature gaps by providing a detailed psychological map to formulate recovery policies previously neglected in early marriage prevention discussions.

The research problem formulation focuses on how religious moderation is practiced and its impact on community dynamics in the village. The aim is to determine the practice and impact of religious moderation in the Naramben Village community. The results of the study indicate that the practice of religious moderation is realized through deliberation and the rejection of violence. As a result, strong social harmony is established, characterized by mutual cooperation and mutual respect regardless of differences. The results of this study are also in line with Peter L. Berger's social construction theory and Lukman Hakim Saifuddin's views, where social reality is shaped through interaction and concrete actions. In conclusion, religious moderation has become the main foundation of social harmony in Naramben Village. As a suggestion, this research has implications for adding to the scientific body and providing input for the village government in formulating policies related to the practice of religious moderation.

This study aims to investigate the determinants of job performance by integrating the variables of capability, social interaction, and Organizational Citizenship Behavior (OCB) as a moderating variable. The phenomenon of employee turnover and discrepancies in staff discretionary behavior within the hospital setting serves as the primary rationale for this study. Using a quantitative approach, data were collected from 240 respondents at Magelang City Islamic Hospital through purposive sampling. Data analysis was conducted using Structural Equation Modeling (SEM) based on AMOS software to test the causal relationships among variables in the structural model. The research findings provide empirical confirmation that individual capabilities and the quality of social inter-actions have a positive and significant influence on stimulating the formation of OCB. Furthermore, statistical test results demonstrate that capabilities, social interactions, and OCB simultaneously make a significant contribution to improving employee work performance. The presence of OCB is identified as a crucial factor capable of strengthening organizational performance outcomes. The practical implications of this study emphasize the need for hospital management to formulate human resource development strategies focused on strengthening technical skills and social cohesion to mit-igate the impact of turnover and accelerate the sustainable performance of healthcare services.

The practice of independent nursing by nurses is a form of professional health services that require assurance of certainty and legal protection, especially after the enactment of Law Number 17 of 2023 concerning Health (Health Law) which integrates various health regulations. This study aims to analyze the form of legal protection for nurses in independent practice and identify the supporting and inhibiting factors for this legal protection. Problem formulation, 1) What is the form of legal protection for nurses who provide independent nursing practice services, 2) What are the supporting and inhibiting factors for legal protection for nurses who provide independent nursing practice. The research method used is normative legal research with a qualitative approach, sourced from secondary data in the form of laws and regulations and related legal literature. The results of the study show that the form of legal protection for nurses includes legality guarantees through STR and SIPP, compliance with professional standards and SPO, and the function of medical records as authentic evidence. The main supporting factors include the existence of a clear legal umbrella and nurses' compliance with regulations, while the inhibiting factors involve illegal practices (without permission), negligence in documentation, and ambiguity of authority. Conclusion: Legal protection for Nurse Practitioners in independent nursing practice is conditional and highly dependent on nurses' compliance with applicable legal norms and professional standards. Compliance with licensing, practice standards, and accurate documentation is the main key in optimizing the guarantee of legal protection.

The cosmetic industry continues to grow rapidly along with the increasing demand for natural-based body care products, one of which is massage oil. Essential oils such as lavender, citronella, and chamomile are known to have synergistic effects as relaxation agents, anxiety reducers, and anti-inflammatory agents. To support the safety and effectiveness of their use, the selection of appropriate carrier oils, such as olive oil, almond oil, and virgin coconut oil (VCO), is required due to their good penetration ability and moisturizing properties. This study aimed to determine the effect of variations in carrier oils on the physical and sensory characteristics of aromatherapy massage oil preparations and to identify the most optimal formulation. The research was conducted experimentally by formulating three massage oil formulations using a combination of lavender, citronella, and chamomile essential oils with different carrier oil compositions. The evaluations included organoleptic tests, pH, viscosity, specific gravity, stability, irritation tests, and hedonic tests. The results showed that all formulations were liquid, homogeneous, stable for 28 days, had pH values within the normal skin pH range, met the required viscosity and specific gravity standards, and did not cause skin irritation. Based on the hedonic test, formulation F2 was the most preferred by respondents and was determined to be the best formulation due to its most favorable aroma, texture, and comfort during use. Therefore, variations in carrier oils influence the characteristics of massage oil preparations and enable the determination of the optimal formulation

This study aimed to form late and evaluate a natural massage oil preparation using a combination of lavender, citronella, and chamomile essential oils with olive oil as the carrier oil. The background of this research was based on the increasing public demand for natural body care products that are safe, non-irritating to the skin, and provide relaxation effects. The three essential oils used possess therapeutic activities, including relaxation, antimicrobial, anti-inflammatory effects, as well as the ability to relieve stress and muscle tension. The study employed three formulation variations (F1, F2, and F3) with different compositions of essential oils. The evaluation of the preparations included organoleptic tests, pH measurement, viscosity, specific gravity, physical stability testing, hedonic testing, and irritation testing. The organoleptic test results showed that all formulations had a liquid form, a deep light-yellow color, and a characteristic aroma corresponding to the dominant essential oil in each formulation. The pH values of all formulations were stable at 5, indicating safety for skin application. Viscosity values were within the ideal range for massage oil, between 4.124–4.735 cPs, and specific gravity values were within the standard range. Stability testing over 28 days revealed no significant changes in color, aroma, pH, or viscosity. The irritation test indicated that none of the formulations caused skin irritation in panelists. Hedonic testing showed that formulation 2 was the most preferred in terms of aroma, while formulation 3 was preferred for texture. Overall, all three formulations were considered stable, safe, and well accepted by consumers, indicating their potential use as natural massage oil products.

Arabic language learning is influenced not only by cognitive ability but also by students’ learning characteristics, including affective, social, and physiological dimensions, particularly the phenomenon of language anxiety that often hinders language performance. This study aims to analyze the relationship between students’ learning characteristics and the emergence of language anxiety in Arabic language learning, as well as to formulate its implications for instructional strategies. This research employs a qualitative approach through a conceptual study based on relevant literature concerning learning characteristics and language anxiety. The findings indicate that variations in students’ characteristics contribute to different levels of anxiety across the four language skills: listening, speaking, reading, and writing. Language anxiety is multidimensional and affects students’ participation, motivation, and academic performance. Therefore, Arabic language instruction should be designed using differentiated, communicative, and student-centered approaches while fostering a supportive learning environment. The study highlights the importance of the teacher’s role as a facilitator who understands students’ cognitive and affective dynamics in order to create more effective, humanistic, and responsive Arabic language learning.

This study aims to examine the influence of local wisdom as a living law on personal data protection behavior, as well as assess the role of Islamic law ethics and digital literacy in the context of intimate digital crime in Indonesia. The background of this research is based on the increasing cases of misuse of personal data in the digital space that have not been fully responded to effectively through formal legal approaches. The method used a quantitative approach with a correlational explanatory design. Data were obtained through the distribution of a questionnaire based on the Likert scale to 150 respondents who were selected purposively, then analyzed using descriptive statistics, Pearson correlation, and simple linear regression. The results showed that local wisdom of alwasliyahan had a positive and significant influence on personal data protection behavior (β = 0.42; p < 0.05). Islamic legal ethics serve as a mediating variable that strengthens the relationship, while digital literacy provides a positive influence at a moderate level. These findings show that the internalization religious and cultural values plays an important role in shaping individual awareness and behavior in protecting personal data in the digital era. The conclusion of this study emphasizes that local wisdom can function effectively as a living law in supporting the protection of personal data. This research makes theoretical contribution the development of the study of Islamic law and the sociology of law, as well as practical implications for policy formulation that integrates formal regulations, cultural values, and digital literacy.
