Litopenaeus vannamei is a brackish-water aquaculture commodity that is highly favored by the Indonesian community and represents one of the country’s leading aquaculture products, with production continuing to increase in response to rising domestic and export demand. One of the main factors triggering disease in L. vannamei is the presence of Vibrio sp. bacteria, which are recognized as serious pathogens in various aquaculture organisms and serve as causative agents of bacterial diseases. These bacteria naturally inhabit marine environments and are categorized as opportunistic, meaning they become pathogenic when environmental conditions decline and host health is compromised. Disinfectants are chemical substances used to inhibit or eliminate microorganisms such as bacteria, viruses, and fungi (excluding bacterial spores) on non-living surfaces. One disinfectant material is Smart Care (Intracare B.V., The Netherlands), which contains stabilized hydrogen peroxide with a prolonged-release mechanism. This study employed an experimental method using a Completely Randomized Design (CRD) with four treatments and five replications. The treatments included a control (without H₂O₂) and applications of H₂O₂ at concentrations of 1 ml/L, 2 ml/L, 3 ml/L, and 4 ml/L. The results indicated that the addition of hydrogen peroxide at different concentrations did not produce statistically significant differences in suppressing the growth rate of Vibrio sp. Nevertheless, treatment C (3 ml/L H₂O₂) showed the highest inhibitory effect, with no bacterial colony growth observed. Therefore, the application of H₂O₂ at 3 ml/L demonstrates potential in reducing Vibrio sp. growth and supporting sustainable shrimp aquaculture practices.

This study examines the relationship between organizational culture and the sustainability of public service innovation within government bureaucracy. Although many public service innovations show positive results in the initial stages, many do not sustain in the long term. This indicates the presence of fundamental factors affecting innovation sustainability, one of which is organizational culture. Organizational culture plays a role in shaping the behavior, values, and work methods of civil servants in providing services to the public. This study aims to analyze the role of organizational culture in supporting or hindering the sustainability of public service innovations. Using a Systematic Literature Review (SLR) approach, this study analyzes 20 relevant scientific articles from 2002 to 2025. The results indicate that hierarchical, rigid, and administratively-oriented organizational cultures hinder innovation sustainability. Other factors such as low leadership support, limited incentives, and resistance to change also strengthen these barriers. Conversely, an open, collaborative, and adaptive organizational culture to change enhances the likelihood of innovation sustainability. In conclusion, the success of public service innovations is greatly influenced by the organizational culture underlying the behavior of civil servants. Therefore, transforming organizational culture to be more innovative and adaptive is a strategic step to strengthen the sustainability of innovation.

The restructuring of Indonesian state-owned enterprises (SOEs) and their subsidiaries following the establishment of Danantara has generated new organizational demands, particularly regarding employees’ psychological preparedness for change. This article develops a quantitative research framework to examine the effects of change communication, transformational leadership, job insecurity, and organizational culture on employees’ readiness for change, with perceived organizational support serving as a moderating variable. The study is designed as an explanatory survey targeting employees of PT Krakatau Steel subsidiaries affected by restructuring. Data are intended to be collected using a five-point Likert-scale questionnaire and analyzed through partial least squares structural equation modeling (PLS-SEM). The article proposes that change communication, transformational leadership, and organizational culture positively influence readiness for change, whereas job insecurity exerts a negative effect. In addition, perceived organizational support is expected to strengthen the positive effects of change communication, transformational leadership, and organizational culture while attenuating the negative effect of job insecurity. The article contributes to the organizational behavior literature by offering a contextually grounded framework for understanding employee responses to restructuring in SOE subsidiaries. It further highlights the strategic importance of organizational support in sustaining employees’ readiness to navigate changes in governance, work systems, and organizational direction.

This study aims to explore the shift in students' ethical paradigms regarding the use of Generative Artificial Intelligence (AI) and its relationship to the phenomenon of plagiarism. Using a qualitative approach with the theoretical frameworks of Jean Baudrillard's Simulacra and Pierre Bourdieu's Habitus, this study examines how AI technology is changing the nature of scientific work. The results show the normalization of AI use as a new "digital habitus," where 83% of students consider AI a legitimate research tool, but on the other hand, it creates a condition of "Aesthetics Without Substance." The main findings reveal a reduction in originality where academic honesty is only measured through technical scores (such as Turnitin), rather than intellectual depth. The comparison between authentic and AI-based writing indicates the risk of systemic intellectual atrophy. In conclusion, this study recommends the need for a redesign of educational evaluation systems that focus on processes and verbal dialectics to mitigate the impact of pseudo-competence on college graduates.

This research is entitled The Influence of Japanese Pop Culture on Children’s Toys Trends in Indonesia, 1980-2010. The study employs the historical method, which consists of four stages: heuristics, source criticism, interpretation, and historiography.John Fiske’s (2011) theory of popular culture and  Joseph Nye’s concept of soft power is used to analyze how Japanese popular culture, particularly through entertainment media and toy products, was disseminated persuasively and received by Indonesian children. Since the early 1990s, mass media such as television and children’s magazines have played an important role in introducing Japanese anime and characters, which subsequently encouraged the emergence of toy trends based on Japanese popular culture. The object of this research focuses on children’s toys influenced by Japanese popular culture that circulated in Indonesia between 1980 and 2010, including Tamiya, Beyblade, Tamagotchi, Crush Gear, B-Daman, and yo-yo. These toys not only developed as commercial products, but also contributed to the formation of children’s play patterns, communities, and social identities. However, during the period from 2008 to 2010, these toy trends began to decline due to the advancement of digital technology, changes in children’s consumption patterns, broadcast censorship policies implemented by Indonesian Broadcasting Commission (KPI), and increasing competition from popular culture of other countries such as Korea, the United States, and China. This condition reflects a shift in children’s play culture from physical toys to more modern forms of digital entertainment.

This paper explores the role of Mary as a model of salvation in Catholic faith, focusing on the understanding of Mariology within the cultural context of the Ende-Lio people in Flores, East Nusa Tenggara. Mary is regarded not only as the Mother of Jesus Christ but also as an example of faith marked by humility, obedience, and hope. Her humility and willingness to accept God’s will, especially in the Annunciation, serve as a concrete inspiration for Catholics to respond faithfully to God’s call. Within the Ende-Lio culture, which values loyalty, solidarity, respect for ancestors, and harmony with nature, Mary becomes a figure closely connected to daily life. Devotions such as the rosary, pilgrimages to Marian grottoes, and the celebration of the Marian months highlight Mary’s living presence in both the faith and cultural traditions of the community. Thus, Mary serves as a bridge between the Gospel and local culture, revealing a Church that is rooted in its own soil yet remains faithful to Christ. This reflection affirms that contextual faith is a living faith deeply rooted in local culture while open to the saving work of God.

This study examines the integration of Christian values into the Merdeka Curriculum for Christian Religious Education (PAK) in junior high schools (SMP), focusing on the challenges and strategies for its implementation. The Merdeka Curriculum, introduced in 2022, offers flexibility in instructional design; however, its implementation in the field of PAK requires specific adaptations to maintain the relevance of Christian values such as love, justice, and responsibility. This study employs a descriptive qualitative approach using library research combined with empirical content analysis of various case studies in Indonesian Christian schools. The findings indicate that the primary challenges include resource constraints, the readiness of PAK teachers, technological infrastructure gaps, and the influence of secular digital culture. Effective strategies include the development of a contextual curriculum based on Christian values, the utilization of digital technology in learning, the enhancement of teachers’ professional competencies, and collaboration between schools, families, and churches. The implications of this study suggest that the integration of Christian values into the Merdeka Curriculum can foster the holistic character of junior high school students, equipping them with integrity, resilience, and the ability to face the challenges of the digital age.

This study aims to analyze the need for redesigning the visual identity of PHD (Peternakan Hijau Daun) Nusantara as an effort to strengthen the brand image as an arts and culture-based educational tourism destination. The problems underlying this research are the inconsistent visual identity, the lack of representation of the brand's character, and the low level of audience recognition of PHD Nusantara. The research methods used include observation, interviews, and questionnaires. The results of the analysis indicate several main factors that form the basis for the need for redesign, namely the inconsistency of visual elements, the weak strength and readability of the logo, the inconsistency of the visual identity with the character of the destination, and the suboptimal visual experience of the audience at various interaction points. Based on these findings, it can be concluded that the development of a more consistent, communicative, and characteristic visual identity is needed as a basis for the redesign process. The results of this study are expected to be a reference in redesigning a visual identity that can strengthen the image of PHD Nusantara and increase its appeal to the audience.

Based on data from FAO (Food and Agriculture Organization of The United Nations), it has been predicted that the aquaculture subsector will become one of the most relied-upon resources in the future, especially in meeting food needs, fish-based nutritional needs, and empowering the global community's economy (FAO, 2016). Catfish is a type of freshwater fish that can grow and develop well because it can be cultivated in limited land areas (Marsela, 2018). The frequency of feeding is one of the important factors that need to be considered in catfish farming. To determine the effect of different feeding frequencies on the absolute weight of dumbo catfish, a study was conducted using an experimental design called the Completely Randomized Design (CRD), with 3 treatments and a total of 8 replications. The test treatments were as follows: Treatment 1 (feeding twice a day), Treatment 2 (feeding three times a day), and Treatment 3 (feeding four times a day). The results of the ANOVA test showed a significant value of 0.000 (P < 0.05), indicating a significant difference in each of the different feeding frequencies. The analysis of the Least Significant Difference (LSD) test at a 5% significance level also showed that the relationship between each treatment had a significant value of 0.000 (P < 0.05). The average absolute weight of the fish for Treatment 1 was 12.99 grams, for Treatment 2 was 15.03 grams, and for Treatment 3 was 17.03 grams. The highest growth in the absolute weight of dumbo catfish fry occurred in Treatment 3 (feeding four times a day).

Vaname shrimp is one of the export commodities with high economic value. Therefore, to meet increasing market demand, it is necessary to improve aquaculture productivity. However, the development of vaname shrimp farming in Indonesia faces several challenges, including the emergence of viral, fungal, and bacterial diseases (Astria et al., 2022). Vibrio sp. bacteria can cause bacterial infections and are opportunistic in nature. Vibrio sp. can attack shrimp at all stages and may lead to decreased production yields (Astria et al., 2022). Generally, farmers control bacterial diseases by adding antimicrobial compounds. However, bacterial disease control in vaname shrimp culture can also be carried out using hydrogen peroxide (Astria et al., 2022). This study examined the effect of different doses of hydrogen peroxide in suppressing Vibrio sp. bacteria using a Completely Randomized Design (CRD). The doses used were 7 ppm, 9 ppm, 11 ppm, 13 ppm, and 15 ppm, with five treatments and five replications. The results showed that the application of different doses of hydrogen peroxide had a significant effect based on the One Way ANOVA test (0.00 < 0.05). The lowest effectiveness was observed in treatment 1 (7 ppm), while the highest effectiveness was found in treatment 5 (15 ppm). Although hydrogen peroxide was able to reduce the number of Vibrio sp. bacterial colonies, the doses used in this study were not able to completely eliminate the colonies (0 cfu/ml).

Vaname shrimp (Litopenaeus Vannamei) is one of Indonesia's fishery commodities with high economic value. Vaname shrimp production in Indonesia continues to increase. However, obstacles sometimes arise in cultivation activities, such as the emergence of shrimp diseases and poor water quality. High stocking density and shrimp feeding can cause a decline in water quality. In addition, pond water quality is influenced by pond location and the surrounding environment, such as agriculture, settlements, mangroves, and the sea. This causes ponds to have different water qualities. One of the diseases that often attacks shrimp farming is caused by the bacterium Vibrio sp. The abundance of Vibrio sp. bacteria is closely related to pond water quality and the environmental conditions around the pond. The methods used were TPC testing and multiple linear regression testing. Based on the results of the study, the abundance of Vibrio sp. bacteria in pond A was the highest at 8.3 x 102, and pond C had the lowest at 3.1 x 102. Water quality testing in three different ponds showed safe limits for cultivation, except for nitrite testing. Based on the simple linear regression test, the water quality parameters that significantly affect the abundance of Vibrio sp. bacteria are pH, temperature, and nitrite.  

The Panji Story is one of the Intangible Cultural Heritage (ICH) that has historical, cultural, and local identity values, especially for the people of Kediri. However, currently, the community's understanding of the Panji Story tends to be limited and is often considered only as a romantic story, so that the historical and cultural values contained therein are not fully understood. This activity aims to strengthen the community's understanding of the Panji Story as a source of history and local cultural heritage through a national seminar. The activity was conducted in the form of a seminar involving presentations by expert speakers, interactive discussions, and question and answer sessions with participants from various backgrounds, such as students, the general public, and cultural activists. The results of the activity showed an increase in participants' understanding and awareness of the historical, cultural, and educational value of the Panji Story. Participants not only understood the diversity of versions of the Panji Story, but also began to view it as an important part of local cultural identity that needs to be preserved and sustained. This activity showed that national seminars can be an effective educational medium in building collective public awareness of the sustainable preservation of local history and culture.

Chrysanthemum is an ornamental plant widely cultivated in Indonesia, with various varieties that have unique and attractive characteristics. Each variety responds differently to changes in light intensity. Providing shade can help regulate the light intensity received by chrysanthemum seedlings during the acclimatization stage. This study aimed to determine the best shade percentage for the acclimatization growth of three chrysanthemum varieties. The research was conducted in the screenhouse of the Faculty of Agriculture, Tanjungpura University, for three months, from October to December 2024. The experiment used a Split Plot Design (Split Plot) with a Randomized Block Design (RBD), consisting of two factors: shade percentage and variety. There were three levels of shade and three chrysanthemum varieties, resulting in nine treatment combinations. Each treatment was repeated three times, with each replication consisting of three sample plants, resulting in 81 experimental units. The shade percentages used were 25% (n1), 50% (n2), and 75% (n3), and the varieties tested were Xanne (v1), Suciyono (v2), and Pinka Pinky (v3). Observed variables included plant survival rate, plant height, stem diameter, internode length, number of internodes, number of flower primordia, leaf color changes, along with supporting data such as temperature, humidity, and light intensity. The results showed that 50% shade was effective in promoting plant height and the number of flower primordia in the three varieties: Xanne, Suciyono, and Pinka Pinky. The Suciyono variety exhibited good vegetative and generative growth under all shade percentages.

This study examines the impact of MBKM, campus culture, and learning achievement on work readiness in Islamic financial institutions, specifically for students from the Faculty of Islamic Economics and Business at UIN Datokarama Palu, Class of 2022. Using a quantitative approach with descriptive research design, the study aims to analyze how these factors influence students' preparedness for work in the industry. The findings show that MBKM, campus culture, and learning achievement each have a positive and significant effect on work readiness. MBKM, with its emphasis on direct industrial experience, has the strongest impact, while campus culture shapes students' character and work ethics. Learning achievement reflects academic competencies essential for entering the workforce. The combined influence of these three factors was proven to significantly impact work readiness, with an F-value of 5.393, greater than the F-table value of 2.72. This demonstrates that work readiness stems from a combination of practical experience, acceptance of campus values, and academic success, all of which should be developed continuously.

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.

The development of digital technology affects tourism promotion strategies. Promotion of cultural tourism in remote areas. The Tarung Traditional Village (KA) is one of the trains located in West Sumba district that has cultural heritage and historical value but still cannot be promoted properly due to the lack of digital media. Therefore, the researcher created a website as a medium for promoting cultural tourism destinations for Tangung Train. The system development method applied is the waterfall model with phases of needs analysis, system design, implementation, and testing. Information collections are carried out through literature studies, observations with traditional and community managers, and direct interviews. The process of developing this system must be able to meet the community's information needs related to the profile of customary areas, customary houses, customary ceremonies, photo galleries and tour guides of the Tarong Train. The result of this research is to get promotional media for the Tarung Train in the form of an informative site about the potential of the Tarung Train containing train profiles, traditional houses, traditional ceremonies, photo galleries, and tourist guides. As well as promotion in the form of a website that is able to increase access to information from the general public and also introduce cultural image.

Leadership constitutes a critical determinant of organizational efficiency, yet the relationship between leadership styles and administrative effectiveness remains incompletely understood, particularly across different institutional contexts. This comparative study examines how transformational, transactional, and laissez-faire leadership styles influence administrative efficiency in public and private sector institutions in Indonesia. Using a mixed-methods approach, quantitative data were collected from 428 employees across 28 public institutions and 24 private organizations through validated survey instruments; qualitative data were gathered through 36 semi-structured interviews with organizational leaders and managers. Results reveal significant positive relationships between transformational leadership and administrative efficiency in both sectors (β = 0.54, p < 0.001 for public; β = 0.48, p < 0.001 for private), with transactional leadership showing moderate positive effects (β = 0.32 public; β = 0.38 private) and laissez-faire leadership demonstrating negative relationships (β = −0.28 public; β = −0.24 private). Leadership styles collectively explain 52% of efficiency variance. Mediation analysis reveals that organizational culture (28%), employee engagement (35%), and trust in leadership (22%) partially mediate transformational leadership's effects, together accounting for 62% of total indirect effects. Sector differences emerged qualitatively: transformational leadership leverages public service motivation in public institutions, while transactional leadership's performance accountability resonates more strongly in private organizations. The study contributes theoretical understanding of leadership effectiveness across institutional contexts and provides practical guidance for developing contextually appropriate leadership development programs.

This study examines the dynamics of Islamic civilization and cultural expressions in Southeast Asia through a comparative analysis of Muslim communities in Indonesia and Thailand. Southeast Asia represents a unique region where Islam has interacted with diverse local traditions, producing distinctive cultural forms and civilizational patterns. The research aims to explore how Islamic values, cultural traditions, and historical experiences shape the development of Muslim societies in both countries.Using a qualitative comparative approach, this study analyzes historical sources, academic literature, and socio-cultural practices within Muslim communities in Indonesia and Thailand. The research focuses on three main aspects: the historical development of Islam, the interaction between Islamic teachings and local cultures, and the role of cultural practices in shaping contemporary Muslim identity.  The findings reveal that Islamic civilization in Southeast Asia is characterized by adaptability, cultural negotiation, and pluralistic expressions. In Indonesia, Islamic cultural expressions tend to be more institutionalized and integrated within national cultural frameworks, while in Thailand, Muslim communities maintain strong cultural identities through local traditions and religious institutions despite existing within a predominantly Buddhist society.  This study contributes to the broader discourse on Islamic civilization by demonstrating that cultural diversity and local adaptation play significant roles in shaping Muslim societies in Southeast Asia. Understanding these dynamics provides deeper insight into the relationship between religion, culture, and civilization in pluralistic societies.

Whiteleg shrimp (Litopenaeus vannamei) is a leading commodity in aquaculture in Indonesia due to a number of advantages such as disease resistance, rapid growth, high survival rate, and feed conversion efficiency. Whiteleg shrimp contributes significantly to Indonesian fisheries exports, reaching 38.98% in 2021. To meet high market demand, increasing the productivity and quality of whiteleg shrimp is very important, where the quality of the shrimp is influenced by the quality of the fry. Good management, including selecting quality broodstock, proper handling of eggs and nauplii, and maintaining optimal water quality, is very important in producing quality whiteleg shrimp fry. This study aims to determine the effect of temperature on the growth length and life expectancy of whiteleg shrimp nauplii. The study was conducted using a completely randomized design with three different temperature treatments (26°C, 29°C, and 32°C). The whiteleg shrimp nauplii used had an average size of 328.24mm obtained from PT. Delta Windu Purnama Situbondo. The water quality parameters used are Temperature, pH, salinity, and DO. Delta Windu Purnama Situbondo. Data were analyzed using SPSS 16.

This research review identifies and analyzes the potential of Romaine lettuce (Lactuca sativa var. longifolia) cultivation using the Nutrient Film Technique (NFT) in greenhouse environments as a high-value horticultural commodity. Horticulture is a strategic sector in Indonesia for improving farmer welfare and meeting the growing demand for healthy food. Conventional farming faces challenges such as land conversion, climate instability, and high pesticide residues. This study examines how the NFT hydroponic system serves as an innovative solution by providing controlled environments that enhance growth and quality. Findings indicate that Romaine lettuce grown via NFT achieves higher productivity and faster harvest cycles, with a feasibility study showing an R/C ratio of 2.40, indicating high profitability. Furthermore, the integration of controlled environment agriculture supports urban farming initiatives and mitigates risks from climate change and pests. This review concludes that adopting NFT technology is essential for developing a sustainable, efficient, and high-quality agricultural system in Indonesia, particularly in urban areas with limited space.
