Abstract

The increasing workload on teaching and administrative staff in Islamic boarding schools has become a crucial issue in human resource management (HR) practices. This study aims to analyze workload distribution, identify influencing factors, and evaluate its impact on overall staff performance. The study employed a qualitative approach through fieldwork, with the research location being an Islamic boarding school in Central Java, purposively selected based on its operational complexity and high academic and non-academic activities. Data collection techniques included in-depth interviews with 15 participants (teachers, administrative staff, and management), participant observation, and analysis of the school's internal policy documents. The results revealed an inequitable distribution of workload across departments. Boarding school teachers, for example, juggles administrative duties and student guidance without adequate compensation or regulation. Nine of the 15 participants reported experiencing emotional exhaustion, loss of work motivation, and exhibiting clear symptoms of burnout. Five of them expressed a desire to transfer or resign. This situation was exacerbated by a lack of standardized tasks, the high demands of 24-hour work in the boarding school environment, and the pressures of an integrated curriculum. Burnout also impacts the quality of interactions between staff and decreases teacher engagement in learning activities. This study recommends the development of job analysis-based work guidelines, enhanced psychological support, time management training, and technology integration to optimize the workload management system sustainably.

Abstract

Culinary small and medium-sized enterprises (SMEs) operate at the intersection of volatile demand, perishable inventories, labor-intensive processes, food-safety and halal-integrity requirements, and growing pressure to reduce waste and improve sustainability. Yet the relevant management literature remains fragmented. Digital transformation studies emphasize technology adoption and decision quality; Green Human Resource Management (Green HRM) research emphasizes employee capabilities and green behavior; food-service studies focus on waste prevention and forecasting; halal supply-chain studies focus on integrity and traceability; and supplier-selection research develops multi-criteria tools with limited integration into day-to-day SME decision cycles. This structured integrative review synthesizes recent peer-reviewed research published during 2022–2025 to develop a cross-functional framework for data-driven sustainability in culinary SMEs. Guided by recent good-practice recommendations for management reviews, the paper integrates evidence across digitalization, Green HRM, green operations, food-waste prevention, halal traceability, sustainable supplier selection, dynamic capabilities, and sustainable business performance. The resulting framework conceptualizes three antecedent capabilities—Green HRM capability, digital decision-support capability, and halal supply-chain integrity capability—that converge into a closed-loop green operational capability. This operational capability links sensing, decision, implementation, measurement, learning, and reconfiguration, thereby generating economic, environmental, human-organizational, and supply-chain integrity outcomes. Eight research propositions specify direct, mediated, and complementary relationships among the constructs. The paper contributes by shifting the debate from isolated green or digital practices toward an integrated decision architecture suitable for resource-constrained culinary SMEs. It also provides a research agenda for empirical validation and a design logic for future smart-green-halal decision-support systems without presuming that a particular technology has already been validated..

Abstract

The textile industry must produce high-quality products with low defect rates to improve competitiveness and customer satisfaction. This research was conducted at the spinning unit of PT. Dan Liris, which still faces problems with bad cone defects in the winding process, such as wrinkles, crossing, ring cones, dirty yarn, and weights that do not meet standards. This study aims to analyse the level of bad cone defects, identify the main causal factors, and provide improvement suggestions to improve yarn product quality. The method used Six Sigma with the DMAIC (Define, Measure, Analyze, Improve, and Control) approach. Data were obtained from the production results of winding machines from July 2024 to March 2025. The analytical tools used include Pareto diagrams, P control charts, fishbone diagrams, and Failure Mode and Effect Analysis (FMEA) to determine improvement priorities based on the Risk Priority Number (RPN) value. The results show that the dominant defects are wrinkles and crossing, with DPMO values and initial sigma levels indicating that the process still needs improvement. The factors causing defects come from aspects of machines, work methods, materials, and people. Kaizen-based improvement proposals reduced the number of bad cone defects, decreased the DPMO value, and increased the process sigma level. Thus, the implementation of the Six Sigma method has proven effective in improving yarn product quality and supporting zero-defect efforts at the spinning unit of PT. Dan Liris.PENGGUNAAN METODE SIX SIGMA UNTUK MENGURANGI CACAT BAD CONE DAN MENINGKATKAN KUALITAS PADA UNIT SPINNING PT. DAN LIRISIndustri tekstil dituntut untuk menghasilkan produk dengan kualitas tinggi dan tingkat kecacatan yang rendah guna meningkatkan daya saing dan kepuasan pelanggan. Penelitian ini dilakukan pada unit spinning PT. Dan Liris yang masih menghadapi permasalahan cacat bad cone pada proses winding, seperti wrinkle, crossing, ring cone, benang kotor, serta berat tidak sesuai standar. Penelitian ini bertujuan untuk menganalisis tingkat kecacatan bad cone, mengidentifikasi faktor penyebab utama, serta memberikan usulan perbaikan guna meningkatkan kualitas produk benang. Metode yang digunakan adalah Six Sigma dengan pendekatan DMAIC (Define, Measure, Analyze, Improve, dan Control). Data diperoleh dari hasil produksi mesin winding periode Juli 2024 hingga Maret 2025. Alat analisis yang digunakan meliputi diagram Pareto, peta kendali P, diagram fishbone, serta Failure Mode and Effect Analysis (FMEA) untuk menentukan prioritas perbaikan berdasarkan nilai Risk Priority Number (RPN). Hasil penelitian menunjukkan bahwa cacat dominan adalah wrinkle dan crossing, dengan nilai DPMO dan level sigma awal yang menunjukkan proses masih perlu ditingkatkan. Faktor penyebab cacat berasal dari aspek mesin, metode kerja, material, dan manusia. Usulan perbaikan berbasis Kaizen mampu menurunkan jumlah cacat bad cone, menurunkan nilai DPMO, serta meningkatkan level sigma proses. Dengan demikian, penerapan metode Six Sigma terbukti efektif dalam meningkatkan kualitas produk benang dan mendukung upaya zero defect di unit spinning PT. Dan Liris.

Abstract

This study aims to analyze the wage gap between natives and immigrants currently working in the real sector in Indonesia. This study uses survey data with a sample of individuals aged between 20 and 55 years. This study uses a quantitative approach, utilizing segmentation analysis techniques. The conclusion of the study shows that immigrants earn higher average wages than natives, this difference is caused by several factors that can be directly identified such as education level, worker bargaining power and the capacity or skills possessed by the workforce. This gap is more pronounced in the middle of the income spectrum, where factors such as discrimination that generally occur in other countries do not occur in Indonesia and immigrant skills are considered better than local citizens. Companies in Indonesia generally still view foreign citizens working in Indonesia as having above average abilities. The suggestion from the study is that it is necessary to review the regulations governing wage policies and improve the protection of workers' rights, especially at the middle-income level, to address this gap. Policies should be focused on increasing local citizens' access to quality jobs, reducing informality in the labor market, and the government should provide active and proactive permission to develop the quality of local human resources by building education and training systems and facilities. This approach aims to create a more qualified and competitive local labor market.

Abstract

Material handling activities in the Inspecting Department of PT Behaestex are still carried out manually, particularly in the process of moving fabric rolls. Fabric rolls weighing approximately 30 kg have to be moved repeatedly, potentially increasing the physical workload of operators. This study aims to determine the level of physical workload of operators, design a material handling aid that meets operator needs and working area conditions, and evaluate changes in physical workload after using the material handling aid. Physical workload was measured using the Cardiovascular Load (%CVL) method based on working and resting pulse rates involving 12 material handling operators. The trolley was designed by considering operator anthropometric data and the working path conditions, which had a width of approximately 1 meter. The measurement results showed that the average %CVL value before using the trolley was 60.1%, while after using the trolley it decreased to 29.7%. Thus, there was a reduction of 30.4 percentage points compared with the initial condition. In addition, material handling operator productivity increased, with the average output rising from 80.4% before using the trolley to 95.3% of the established target of 95%, representing an increase of 14.9 percentage points. These results indicate that the use of the trolley reduced operator fatigue, as indicated by the decrease in physical workload based on the %CVL value. The designed trolley can serve as an alternative material handling aid for fabric roll transportation activities in the Inspecting Department.
