Abstract

Centrifugal pumps are widely used in industrial applications and educational laboratories because of their simple construction, ease of operation, and ability to provide a stable flow rate. This study aims to analyze the performance of the CALPEDA BCM 20E centrifugal pump through experimental testing as a laboratory learning medium. In addition, the study develops a practical testing system by integrating transparent piping and a digital flow meter to improve the accuracy of flow rate measurements and enable direct observation of fluid flow. The research employs an experimental method by operating the pump under several operating conditions to obtain data on flow rate, total head, hydraulic power, shaft power, and pump efficiency. The collected data are analyzed using fundamental fluid mechanics equations and centrifugal pump performance characteristics and are presented in the form of tables, graphs, and performance curves. The developed laboratory equipment is expected to improve students' understanding of fluid flow phenomena and the relationship among flow rate, head, hydraulic power, and pump efficiency. The findings of this research are expected to provide useful information for evaluating centrifugal pump performance and support the development of more effective and interactive laboratory learning media.

Abstract

This study aims to analyze the transformation of Islamic Religious Education (PAI) in addressing the challenges of Islamic economics in Labuhanbatu Regency. The rapid development of Islamic economics requires human resources who not only possess religious understanding but also have economic competencies based on Islamic values. This study employed a qualitative approach with a descriptive method. Data were collected through interviews, observations, and documentation conducted at Islamic educational institutions in Labuhanbatu Regency. Data analysis was performed using the interactive model of Miles, Huberman, and Saldaña, consisting of data collection, data condensation, data display, and conclusion drawing. The results indicate that the transformation of Islamic Religious Education is carried out through the development of an Islamic economics-based curriculum, innovation in learning methods, improvement of teacher competencies, and strengthening of students’ Islamic economic literacy. However, the implementation of this transformation still faces several challenges, including limited teachers’ understanding of Islamic economics, the lack of optimal integration of Islamic economic materials into the curriculum, and limited relevant learning resources. This study emphasizes that the transformation of Islamic Religious Education plays a strategic role in developing a generation that is religious, competent, and capable of supporting the sustainable development of the Islamic economic ecosystem.

Abstract

Collective Labour Agreements (CLA) constitute one of the essential instruments in the Indonesian industrial relations system. Beyond functioning as a product of collective bargaining between employers and trade unions, a CLA also serves as a legal instrument aimed at ensuring legal certainty regarding the rights and obligations of both parties in employment relations. In practice, however, legal protection for outsourced workers remains a significant issue, particularly due to their vulnerable employment position, contractual uncertainty, and limited bargaining power. This study examines the position of Collective Labour Agreements in guaranteeing legal certainty for outsourced workers’ rights in Indonesia. Employing a normative legal research method with statutory, conceptual, and case approaches, this study analyzes relevant legislation, legal doctrines, judicial decisions, and scholarly works concerning industrial relations and outsourcing arrangements. The findings indicate that Collective Labour Agreements possess a strategic position as a source of labour law capable of strengthening legal protection beyond the minimum standards established by legislation. Nevertheless, the effectiveness of such agreements in protecting outsourced workers remains constrained by the absence of explicit clauses, unequal bargaining positions, and inconsistencies in implementation. Therefore, strengthening the substance of Collective Labour Agreements is necessary to ensure greater legal certainty and protection for outsourced workers within the Indonesian industrial relations framework.

Abstract

 This study aims to analyze the legal position of Government Employees with Work Agreements (PPPK) within the State Civil Apparatus (ASN) system, as well as to examine the rights and obligations of PPPK and their differences from Civil Servants (PNS). The research method used is a qualitative method with a normative juridical approach through a literature study of relevant laws and regulations. The results show that PPPK holds a legitimate legal position as part of ASN and has a strategic function in the administration of government. However, the contractual nature of PPPK's employment status has implications for job security, social security, and career development. In addition, there remain differences in treatment between PPPK and PNS that have the potential to create inequality within the civil service system. Therefore, more comprehensive strengthening of regulations and policies is needed to ensure legal certainty and to create a fair and professional ASN system.

Abstract

Occupational safety during mooring and unmooring activities is an important aspect in ship operations because these activities have a high risk of accidents, especially due to snap-back hazards, work environment conditions, and human factors. This study aims to identify potential hazards, analyze the level of occupational accident risk using the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method, and determine risk control measures in mooring and unmooring activities on board the MV. CTP Honour. The study uses a descriptive quantitative approach. The study population includes all mooring and unmooring activities and the crew involved, while the sample is focused on the crew's work activities in the deck area during the mooring and unmooring process. Data were collected through observation, interviews, and documentation, then analyzed using the HIRARC method. The results showed that there were 20 potential hazards consisting of 4 Extreme Risk categories, 11 High Risk categories, and 5 Medium Risk categories. The highest risks were found in activities related to mooring rope tension and the presence of crew in the snap-back zone area. The research conclusion shows that the implementation of risk control through increased supervision, implementation of safety meetings, use of PPE, effective communication, and compliance with SOPs can minimize the risk of work accidents during mooring and unmooring activities on board ships.

Abstract

Karawang Regency is one of Indonesia’s major industrial growth areas, attracting a large number of workers who require decent, affordable, and accessible housing near workplaces. However, the provision of simple vertical rental housing for industrial workers cannot be formulated only through minimum technical building standards, because workers have diverse residential status, household composition, economic capacity, work patterns, and daily mobility. This study aims to formulate the spatial and facility requirements of simple rental vertical rental housing for industrial workers in Karawang based on user characteristics and residential behavior. The study applies a descriptive-qualitative approach based on architectural design inquiry. Data were collected through literature review, site observation, precedent studies, regulatory review, and analysis of user activities. The analysis traces the relationship between worker characteristics, housing needs, daily activities, spatial requirements, space types, spatial character, and basic design principles. The findings show that industrial workers should be understood as heterogeneous users, including single workers, partnered workers, and small-family workers, each with different privacy needs, activity patterns, and facility demands. The required spaces include private dwelling units, service areas, transitional spaces, communal areas, and supporting facilities such as motorcycle parking, laundry areas, drying spaces, small shops or cooperatives, prayer rooms, management offices, security posts, open spaces, and health facilities. The study concludes that basic design standards for workers’ vertical rental housing should emphasize affordability, spatial efficiency, privacy, resting comfort, daylighting, natural ventilation, safety, ease of maintenance, workplace accessibility, and social spaces that do not disturb private areas.

Abstract

This study aims to develop a conceptual framework regarding the role of educational leaders who are capable of integrating digital capabilities with spiritual leadership from the perspective of Islamic Educational Management. This study employs a qualitative approach using a case study design at Madrasah Aliyah Raudhatut Tholabah Setail Genteng in Banyuwangi to examine the integration of digital transformation and spiritual leadership in Islamic educational leadership. The research was conducted over one month, involving six non-participatory observations, and included four informants—the madrasah principal, the vice principal for curriculum, a senior teacher, and an administrative staff member—through semi-structured interviews and documentation. Data analysis was conducted interactively through condensation, presentation, and drawing of conclusions using a phased coding technique and triangulation to ensure data validity. The results indicate that educational leadership at Madrasah Aliyah Raudhatut Tholabah has evolved into an integrative model that combines digital transformation with spiritual values within Islamic Educational Management. This shift does not alter the substance of leadership duties but expands managerial practices through the use of technology that remains grounded in ethics, responsibility, and the public good. Technology serves not only as a tool for efficiency but also as a means of strengthening transparency, accountability, and the quality of educational services. These findings affirm that modernization need not lead to technical dominance but can instead reinforce moral and spiritual values. This study contributes to highlighting the importance of integrating digital competencies and values in leadership and demonstrates that madrasahs serve as models for harmonizing technology and religious character. Further research is recommended to test this model in a broader range of Islamic educational institutions using more measurable indicators.

Abstract

This study aims to analyze and reveal how professional allowances provided through the teacher certification program contribute to teachers’ actual teaching productivity at Darussalam Junior High School in Blokagung, Banyuwangi. This study employs a qualitative approach using a case study design to analyze the contribution of professional allowances to teachers’ teaching productivity at Darussalam Junior High School in Blokagung, Banyuwangi. The research was conducted in May 2026, involving four informants selected through purposive sampling, consisting of the principal, the vice principal for curriculum, and two certified teachers. Data were collected through observation, semi-structured interviews, and document analysis, then analyzed using the Miles, Huberman, and Saldaña interactive model through the stages of open coding, axial coding, and selective coding. Data credibility was ensured through source triangulation, methodological triangulation, and member checking. The results indicate that professional allowances can enhance teachers’ work motivation and sense of responsibility as professionals, but do not automatically increase teaching productivity. Learning productivity is more strongly influenced by teachers’ professional commitment, as reflected in their willingness to continue learning, innovate, and develop adaptive teaching strategies. This study emphasizes that the effectiveness of certification cannot be adequately measured solely by improvements in well-being or certificate ownership, but rather by teachers’ ability to actualize their competencies in teaching practice. These findings broaden the perspective on certification policy evaluation by positioning Teacher Professional Capital and Professional Commitment as the foundation for building a performance-based evaluation system aimed at continuously improving the quality of learning.

Abstract

This study examines the role of Pecalang in the social surveillance of foreigners in Canggu Traditional Village, Bali, and its integration with local cultural governance and the formal immigration system. Using a non-interview qualitative approach based on administrative data from the Ngurah Rai Class I Special TPI Immigration Office, this study documents the dynamics of community-based social oversight in the context of globalization, international migration, and global tourism. Data on administrative immigration actions specifically deportations and enforcement measures against foreign nationals were obtained directly from the Immigration Office for the period 2024–2025. The findings reveal that Pecalang performs an adaptive function beyond securing traditional ceremonies, acting as a social monitor of the activities of tourists, digital nomads, and foreign investors. This function is reinforced through collaboration with immigration authorities, enabling early detection of potential legal and social violations. The integration of awig-awig (customary law) and formal regulations creates a synergy of community-based oversight that enforces socio-customary norms while ensuring compliance with national laws. The study also highlights the challenges posed by conflicting interests between tourism development and cultural preservation. Administrative data from Ngurah Rai Immigration Office shows a total of 300 deportation/administrative actions in 2024 and 337 in 2025 a 12.3% increase indicating growing immigration enforcement activity in Bali. These local mechanisms contribute significantly to community resilience, enabling communities to adapt to external changes without losing their cultural identity. Based on empirical findings, the study develops a conceptual model of community-based immigration oversight emphasizing early detection, preventive supervision, and enforcement of socio customary norms through collaboration among Pecalang, Traditional Villages, and formal authorities
