Abstract

Customer loyalty in MSMEs does not grow spontaneously, but is a resultant of planned strategic interventions. This study examines two managerial instruments marketing strategy and Customer Relationship Management (CRM) as determinants of customer loyalty at UD Sumber Agung, a shallot distribution business actor in Nganjuk Regency. By involving 96 respondents selected using the Cochran formula, the research instrument was verified through validity and reliability tests before the data were analyzed using multiple linear regression. The estimation results result in the equation Y = 4.678 + 0.324X₁ + 0.456X₂, where CRM displays a more dominant coefficient weight. Partial tests confirmed the significance of marketing strategies (t = 3.874; sig. = 0.000) and CRM (t = 3.192; sig. = 0.002). Simultaneously, both had a significant effect on customer loyalty (F = 48,220; sig. = 0.000). These findings confirm that the synergy between structured marketing and adaptive customer relationships is an irreplaceable combination in building consumer loyalty in MSME-scale commodity trading businesses

Abstract

This study aims to examine in depth the meaning of moral warnings conveyed to the bride in the Wotik Wawi Waten rite in the Kloangpopot indigenous people. This rite is an important part of the traditional marriage series that is full of cultural values and life norms that have been passed down from generation to generation. The approach used in this study is qualitative descriptive, with data collection techniques through participatory observation, in-depth interviews with traditional leaders and cultural actors, and documentation of the practice of the rite. The results of the study show that there are six main values contained in the message, namely the recognition of origin and family ties; integration in the husband's family; self-control and social ethics; loyalty and togetherness; expectations of fertility and continuity of generations as well as simplicity and value orientation. These values are conveyed through symbolic and meaningful indigenous languages, so that they not only function as advice, but also as a means of cultural transmission and the formation of identity and the role of women in the Kloangpopot community. Thus, this rite has a strategic role in maintaining the sustainability of cultural values while strengthening the social structure of indigenous peoples

Abstract

A large body of literature treats social capital, trust, norms, and networks as assets that improve schools. However, many schools rich in relational resources remain slow to adapt and innovate, suggesting that social capital is a potential rather than an automatic outcome. This study examines why some schools convert relational resources into organizational capacity while others do not and develops the concept of social capital activation, namely the process through which school leaders intentionally transform relational resources into collective organizational action. Using a qualitative multiple-case study of two state Islamic senior secondary madrasahs in Lamongan, East Java, and interviews with principals, teachers, staff, students, and parents, four themes emerged: dormant social capital, leadership activation mechanisms, conversion into learning and adaptive capacity, and the dark side of excessive bonding capital. The findings demonstrate that activation, rather than accumulation, turns relationships into organizational power

Abstract

The collective perception of sacred time in contemporary Hindu communities is an important aspect of understanding the relationship between religious practices, cultural values, and sustainability decisions in the midst of modern social change. This research aims to explore how the Hindu community interprets sacred time and how this meaning affects the vulnerability of sustainability decision-making. This study uses a qualitative approach with a case study design; Data were collected through in-depth interviews, participatory observations, and documentation of 16 purposively selected informants, including religious leaders, traditional leaders, and community members. Data were analyzed using thematic analysis through the process of reduction, categorization, interpretation, and conclusion drawn. The results of the study show that the ritual calendar, holy days, and dharma values form a collective consciousness in maintaining a socio-ecological balance. This research contributes to the development of religious studies and sustainability based on local wisdom

Abstract

The Central Kalimantan Public School Construction Project involves building activities at several sites with varying conditions, such as peat soil, difficulties in transportation, severe weather, and limitations in material supply. These factors could affect the overall expenses and timelines of the project, highlighting the need to analyze their impact on how well the project performs. This research intends to examine the timeline for the Central Kalimantan Public School Construction Project and assess how well the schedule is monitored through the Critical Path Method (CPM). A case study was conducted using both descriptive and evaluative techniques. The information gathered included the original contract, any modifications, schedules, and reports on work progress. The CPM analysis was performed to pinpoint the critical path and the key activities that could affect the project's duration. The findings suggest that the conditions of the site have an effect on the project's timeline. The CPM analysis identified vital activities that need to be managed to achieve the project's completion goals. Using the CPM approach can help in controlling the schedule and in making informed decisions during the project's implementation

Abstract

Fast fashion is driving the global fashion industry and contributing greatly to environmental degradation through greenhouse gas emissions and textile waste. The positive attitude of Indonesian Generation Z consumers, particularly college students, towards sustainability does not always match their consumption of sustainable fashion, creating an attitude-behavior gap. The existing studies have mainly concentrated on the psychological barriers of the individual and neglected the wider interaction between stakeholders that affect consumption behaviour. This research aims to fill the gap by applying Soft Systems Methodology (SSM) in studying the complex fashion service ecosystem in Indonesia. The study developed a Rich Picture to identify systemic issues, a CATWOE-based root definition to clarify transformation goals and a Conceptual Model to guide coordinated interventions through participatory workshops with students, fashion brands, policymakers, educators and social media influencers. The results show that structural barriers, such as high product prices, weak policy enforcement, and conflicting social norms, reinforce the attitude–behavior gap by reducing perceived behavioural control and encouraging the continuation of fast-fashion consumption. Theoretically, the study contributes by integrating the Theory of Planned Behaviour and Service-Dominant Logic within a systems perspective. It recommends interventions such as multi-stakeholder governance, sustainability education and co-creation platforms to improve accessibility, strengthen stakeholder alignment and promote consumption of sustainable fashion in Indonesia and emerging markets

Abstract

This study analyzes modern warfare strategies used in the US–Israel versus Iran conflict and their implications for global economic stability. The main problem is the lack of an analytical model that integrates the military, energy geopolitics, and global economic dimensions in a single analytical model. The research gap so far shows the dominance of partial and linear approaches. This study, however, utilizes Clausewitz's theory, structural realism, deterrence, and complex interdependence with a system dynamics approach. Previous studies tended to be sectoral, while this study is integrative. A qualitative explanatory methodology with causal loop diagrams was used, based on data from OPEC, the IMF, and the IEA, and expert interviews. The results demonstrate a non-linear relationship through feedback mechanisms between conflict, supply chain disruptions, and global inflation. The analysis confirms that deterrence serves as a systemic balancing element. This study concludes that modern warfare functions as a global economic and political instrument. The novelty of this study lies in its non-linear integrative model. This research contributes theoretically and practically, with implications for energy independence policies and national defense strategies to address an increasingly complex spectrum of threats

Abstract

The evolution of modern weapon systems has significantly transformed contemporary warfare, particularly through the transition from precision-guided munitions (PGMs) to autonomous lethal systems enabled by artificial intelligence (AI). This systematic literature review (SLR) synthesizes peer-reviewed studies to examine technological development, operational effectiveness, and ethical-legal implications of modern weapon systems. Following PRISMA guidelines, 78 eligible studies were analyzed from leading scientific databases including Scopus, IEEE Xplore, and Web of Science. The findings indicate that PGMs have enhanced strike accuracy and reduced collateral damage, while autonomous weapon systems introduce new complexities regarding decision-making, accountability, and compliance with International Humanitarian Law (IHL). The review highlights an accelerating trajectory toward autonomy in warfare, raising critical concerns regarding human oversight and machine-based lethal decision authority

Abstract

Pediculus humanus capitis lives on the skin and hair of the human head, sucking blood, causing itching, hair clumping, secondary infections, and a foul-smelling head. Head lice treatment can use natural ingredients such as starfruit and lime, because they contain active chemicals that can kill head lice. This experimental study aims to determine the effectiveness of starfruit juice and lime on the mortality of Pediculus humanus capitis at the same concentrations of 11%, 12%, and 13%. Each treatment was tested on 5 adult lice with 3 repetitions and a maximum observation time of 45 minutes. Data analysis used a probit test. The average time to death for starfruit concentrations of 11% was 39 minutes, 12% was 36 minutes, 13% was 33.33 minutes, and lime concentrations of 11% was 45 minutes, 12% was 43.66 minutes, and 13% was 37.66 minutes. Starfruit is more effective in killing head lice than lime at the same concentrations

Abstract

This article examines the relationship between family apathy, cyber engagement, and self-radicalization in the escalation of lone wolf terrorism in Indonesia. It highlights the shift of terrorist threats toward more fluid, individualized, and decentralized forms, positioning the family as an upstream factor influencing vulnerability or resilience to extremist propaganda. The study uses a qualitative multiple-case study design based on secondary data, including academic literature, policy documents, institutional reports, and relevant case narratives. The analysis applies concepts of lone wolf terrorism, self-radicalization, cyber engagement, family apathy, the staircase to terrorism theory, significance quest theory, and shortcut to terrorism. Findings indicate that family apathy does not directly cause terrorism but generates psychological vulnerabilities such as alienation, identity crisis, and the search for personal significance. These vulnerabilities are exploited through digital spaces that accelerate self-radicalization. The study proposes a family apathy–cyber engagement–lone wolf escalation model and recommends family-based prevention strategies
