The use of moldboard plows in agricultural land preparation often faces wear problems on the share component, leading to increased maintenance time and reduced operational efficiency. This study aims to design and analyze a modular concept for the plow share to improve maintenance and repair efficiency without compromising structural performance. The research methods include field observation, component dimension measurement, design modeling using CAD software, and structural analysis using the Finite Element Analysis  (FEA) method. In addition, maintenance ease was evaluated through a questionnaire based on a rating scale. The results show that the modular design significantly improves maintenance and repair efficiency, with an average score of 4.59 categorized as very good. Structural analysis indicates that the modular design reduces maximum stress on the moldboard and slightly decreases deformation, reflecting improved structural stiffness compared to the conventional design. However, the Safety Factor on the share component remains below the acceptable limit, indicating the need for further development. Overall, the modular design provides an effective solution to enhance maintenance efficiency while maintaining the structural performance of the moldboard plow.

The shaft is a crucial component in mechanical systems because it serves to transfer power and rotational motion throughout the machine. This research aims to assess the structural strength and operational performance of shafts used in a tire shredding machine through numerical simulation methods in order to achieve a safe and efficient design. The study involved several stages, including the development of shaft geometry models, the determination of boundary conditions, load application, mesh generation, and stress analysis using the finite element method. Two shaft configurations were examined: a 59 mm diameter shaft made from AISI 1045 steel and a 49 mm diameter shaft manufactured from ASTM A36 steel. The simulation results indicate that the 59 mm shaft experiences a Von Mises stress of 8.9 × 10⁻⁵ MPa, with a maximum displacement of 0 mm and a safety factor of 15. Similarly, the 49 mm shaft shows a Von Mises stress of 8.4 × 10⁻⁵ MPa, no measurable displacement, and a safety factor of 15. These findings confirm that both shaft designs are capable of safely withstanding the applied working loads. In addition, cutting system tests revealed that a 24-tooth blade achieved an efficiency of 26.9%, while a 40-tooth blade reached only 22.3%, indicating that the 24-tooth configuration provides better performance.

This study analyzes the Public Relations communication strategy of PT Kereta Api Indonesia (Persero) Daerah Operasi 8 Surabaya in socializing the Access by KAI digital application to the Surabaya community. Using a descriptive qualitative approach, data were collected through in-depth interviews with PR staff and Railfans Surabaya community members, participatory observation of socialization activities, and documentation of digital publications. Data analysis followed the interactive model of Miles, Huberman, and Saldana (2014). The findings reveal that PR communication strategies are implemented through a synergy of push communication, pull communication, and pass communication, supported by Two-Way Symmetrical Communication principles developed by Grunig and Hunt (1984). Push communication disseminates official information via social media platforms; pull communication attracts audiences through visually compelling and educational content; while pass communication emphasizes two-way engagement that builds public trust and loyalty. The study demonstrates that public engagement, interactive dialogue, and message adaptation to local audience characteristics positively contribute to increasing public understanding and acceptance of the Access by KAI application. The integration of these three strategies creates a holistic communication ecosystem that effectively bridges the gap between digital innovation and user behavior. Future research is recommended to examine similar strategies in other operational regions or employ quantitative approaches to measure adoption levels.

 This study was conducted to evaluate the influence of Total Asset Turnover (TATO), Debt to Equity Ratio (DER), and Net Profit Margin (NPM) in predicting stock return fluctuations. The study focuses on retail sector issuers listed on the Indonesian Stock Exchange (IDX) between 2021 and 2024. Through the application of panel data regression analysis, the study determined that the Common Effects Model (CEM) is the most appropriate estimation method. This decision was made based on a series of tests including the Chow Test and the Lagrange Multiplier. Although classical assumption testing showed symptoms of heteroscedasticity, this problem was addressed using the EGLS (cross-sector weighting) Panel method to ensure the validity of the estimates. Based on partial testing, it is found that TATO and NPM variables have a positive and significant contribution to stock returns, while DER is found to have no significant effect. Collectively, all independent variables had a significant effect, with the Adjusted R-Square value reaching 27.80%. This indicates that for investors in the retail sector, profitability and operational efficiency are important indicators in making investment decisions.

The management of ethical drug inventory is a crucial aspect of supporting the smooth delivery of healthcare services in hospitals.

Abstract This study aims to analyze the level of digital literacy among students of the Islamic Religious Education (PAI) study program at State Islamic Higher Education Institutions (PTKIN) and its implications for the quality of their understanding of fiqh al-ibadah. Employing a descriptive qualitative approach with data collection techniques comprising comprehensive literature study and analysis of student digital behavior trends, this research identifies two poles interacting dynamically: on one hand, the expansion of access to religious content through digital platforms has opened unprecedented opportunities for democratizing Islamic jurisprudence knowledge; on the other, the tendency toward instant content consumption potentially reduces depth of understanding of ijtihad methodology and classical fiqh epistemology. Findings indicate that PAI students generally possess adequate technical digital skills, yet remain weak in the critical literacy dimension namely the ability to evaluate the validity, authority, and religious context of digital sources. This phenomenon produces a literacy paradox: students who appear "digitally literate" operationally are paradoxically vulnerable to fragmented and superficial fiqh understanding. This study recommends integrating critical digital literacy education into the PAI curriculum at PTKIN  not as an elective add-on, but as a core competency embedded inseparably within the broader process of fiqh learning. Only through this approach can PAI students leverage digital platforms optimally as tools that strengthen, rather than replace, the structured and methodological tradition of Islamic scholarship

The research employs a qualitative approach with a case study design, where data were collected through semi-structured interviews, participatory observation, and documentation involving youth members, tourism managers, and the local community. The findings indicate that youth play an important role in operational management, digital promotion, and community-based tourism activities, supported by strong values of mutual cooperation and natural resource potential. However, several challenges remain, including limited funding, lack of training opportunities, and inadequate infrastructure. These findings highlight that youth act not only as implementers but also as key drivers and innovators, emphasizing the need for capacity building through continuous training and institutional support. Theoretically, this study enriches the discourse on youth participation in tourism, while practically providing recommendations for village governments and stakeholders.

The issue of education financing in Indonesia, particularly in Islamic educational institutions, remains a challenge even though the national education budget has reached 20%. High operational costs, uneven budget distribution, and limited resources are obstacles to improving the quality of education and empowering the Islamic community. In this case, productive waqf presents itself as a sharia economic instrument that has the potential to support sustainable education financing and community development. This study aims to analyze the management strategy of productive waqf in empowering the Islamic community at the Lampung Al-Qur'an Center (LAC) and review it from the perspective of Islamic jurisprudence (fiqh muamalah) and waqf management. The study used a field method with a descriptive qualitative approach through interviews, observation, and documentation. The theories used are George R. Terry's management theory and Jim Ife's community empowerment theory. The results show that the productive waqf management strategy at LAC is carried out through waqf fund collection, management of Al-Qur'an education, socio-religious development, and community empowerment programs based on Islamic education. This management contributes to improving the quality of education, strengthening Islamic values, and social and economic empowerment of the community. From a muamalah jurisprudence perspective, the practice of productive waqf in LAC has a strong sharia basis because it is oriented towards the welfare of the community and the sustainability of the waqf's benefits. Thus, productive waqf in LAC can be an alternative for financing Islamic education and sustainable community empowerment.

This study aims to evaluate the effectiveness of implementing an application-based water payment system as a strategy to reduce consumer arrears. Payment delinquency remains a significant challenge in the management of water utility services, often driven by low payment discipline, limited access to transaction channels, and the inefficiencies of conventional manual systems. Employing a quantitative approach, this research utilizes comparative data collected before and after the implementation of the digital payment application, supported by statistical analysis to measure changes in consumer payment compliance. The findings indicate that the adoption of an application-based payment system has a substantial positive impact on reducing arrears, as reflected in increased payment timeliness and a decline in the number of delinquent consumers. Features such as ease of access, automated notifications, and transparent billing information are proven to enhance consumer compliance behavior. These results underscore that the digitalization of payment systems can serve as an effective solution for improving operational efficiency and supporting the sustainability of water utility services.

This research deconstructs the manipulative architecture in the propaganda trilogy of the Japanese Army in 1942, namely Nippon Tjahaja Asia, Nippon Pelindoeng Asia, and Nippon Leader Asia, which have often been reduced to mere political euphemisms. With a descriptive-qualitative design, this study integrates Malcolm Coulthard and Alison Johnson's parameter-based Forensic Linguistics as the grand theory, as well as the three-dimensional model of Norman Fairclough's Critical Discourse Analysis (AWK) as an operational analysis instrument. The results of the analysis show that lexical manipulation through the messianic triptych "Light, Protector, Leader" and the use of assertive clauses without copula are engineered to produce false consciousness. Forensic Linguistic Parameters confirm the existence of a planned mens rea (malicious intent) from Sendenbu, with an extreme disparity between commissive speech in the form of a promise of protection and military actus reus in the form of romusha slavery and logistical seizure. This condition fulfills the elements of mass deception. Furthermore, the doctrinal repetition of the slogan is a form of linguistic coercion that exploits power asymmetry to castrate the people's critical reasoning. In conclusion, the invasion of Japanese fascism in Indonesia did not only take place through military equations, but also through a cognitive dictatorship based on language fabrication. This study is relevant as a historical mirror for detecting the anatomy of structural lies in the contemporary post-truth era.

This study contributes to the development of cultural-based SME studies by positioning digitalization and sustainability as key foundations for strengthening local economic performance.

This community service activity aims to instill religious values in the students at TPQ Miftakhul Huda by establishing the habit of praying before and after wudu, as an effort to transform worship practices from mere physical routines into profound spiritual experiences. Using the Asset-Based Community Development (ABCD) approach, this program is carried out through five main stages: discovery, dream, design, define, and do. The results of the activity indicate that through intensive demonstration and practical guidance, the students experienced significant improvement in discipline, awareness of maintaining purity, and moral responsibility as manifestations of Muslim character from an early age. Integrating prayer into the wudu practice has proven effective as an educational tool in building the foundation of faith from an early age, or the “golden age.” The synergy between the student team, educators, and the utilization of institutional facilities proved effective in establishing operational standards for character education that comprehensively integrate physical, mental, and theological aspects. Thus, the practice of wudu prayer serves as a strategic educational tool in strengthening children’s foundational faith during the golden age amidst the challenges of shifting global values.

This study examines the transportation management flow at PT Xpresindo Logistik Utama Medan Warehouse and its impact on delivery accuracy. The research method used a qualitative approach through direct observation and interviews with warehouse managers and operational staff. The results showed that the distribution flow from receiving goods from Jakarta to shipping to customers in Medan was quite effective, although it was still dominated by manual systems such as the use of Delivery Notes and Excel records. The use of the Monstra tracking application was not evenly distributed, so fleet movement information was not always updated in real time, especially when demand volume increased at the end of the month. To improve efficiency, the study recommended the implementation of a Transportation Management System (TMS), digitalization of barcode/QR code-based inventory processes, and a Key Performance Indicator (KPI) dashboard to monitor delivery timeliness and fleet utilization periodically.

This systematic literature study conducts a comparative analysis of Reliability-Centered Maintenance (RCM) and Total Productive Maintenance (TPM) in manufacturing, and proposes an integrated hybrid model. The research concludes that RCM and TPM are fundamentally distinct methodologies: RCM excels in risk-based, analytical management of complex, high-criticality assets, while TPM is superior for achieving broad-based productivity gains and cultural empowerment through total employee involvement. The effectiveness of each approach is contingent upon factors such as asset characteristics, organizational culture, data availability, and level of automation. To leverage their complementary strengths, the study proposes the Synergistic RCM-TPM Hybrid Model (SRTHM). This framework advocates for a sequential implementation where TPM establishes the foundational operational stability, discipline, and data culture, upon which selective RCM analysis is applied to critical assets for precision risk management. The model incorporates explicit feedback mechanisms to create a continuous organizational learning cycle. The study provides a contingency framework for methodology selection and a practical roadmap for integration, offering theoretical and practical guidance for building more resilient and context-appropriate maintenance systems in modern manufacturing.
