Abstract

The mining industry operates in a high-risk environment in which transportation activities contribute significantly to occupational accidents and operational losses. In Indonesia, transportation-related incidents in mining operations remain a critical safety issue, highlighting the need for systematic and sustainable improvement approaches. This study aims to analyze the implementation of the Plan–Do–Check–Act (PDCA) method as a continuous improvement framework in reducing transportation-related incidents within a coal mining contractor operating in South Kalimantan. This study employs a qualitative case study approach. Data were collected through direct field observations conducted during an industrial internship, semi-structured interviews with key personnel involved in the improvement program, and analysis of internal company documents related to safety performance and continuous improvement initiatives. The PDCA framework was used as the primary analytical lens to examine improvement activities across the planning, implementation, evaluation, and standardization stages. The findings indicate that the PDCA method was effectively implemented to identify dominant transportation safety risk factors, particularly unsafe driving behavior and limitations in manual monitoring systems. Improvement actions implemented during the Do stage included the adoption of digital fit-for-duty systems, enhanced transportation monitoring technologies, and strengthened supervisory coaching. The Check stage demonstrated measurable improvements in safety compliance and reductions in unsafe driving behavior, while the Act stage focused on standardizing successful practices to support sustainability. This study concludes that the PDCA method functions as an effective continuous improvement tool for strengthening transportation safety management in high-risk mining operations. The findings provide practical insights for mining contractors seeking to enhance safety performance through structured, data-driven, and sustainable improvement cycles.

Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) memiliki peran penting dalam perekonomian daerah, termasuk di Jawa Tengah. Namun, peningkatan kinerja operasional UMKM khususnya di Jawa Tengah masih menjadi tantangan yang perlu diatasi melalui peningkatan strategi inovasi operasional yang tepat. Penelitian ini bertujuan untuk menganalisis pengaruh Technical Lean Practices (TLP) dan Human Lean Practices (HLP) terhadap Operational Performance (OP) pada UMKM di Jawa Tengah. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei melalui kuesioner skala Likert 1–5. Sampel penelitian berjumlah 60 UMKM yang berada di wilayah Purworejo, Wonosobo, Magelang, Semarang, Temanggung, dan Kebumen, yang ditentukan berdasarkan pertimbangan aksesibilitas waktu dan biaya. Analisis data dilakukan menggunakan teknik Partial Least Squares Structural Equation Modeling (PLS-SEM) dengan bantuan perangkat lunak SmartPLS versi 4.1.1.6. Hasil penelitian menunjukkan bahwa Technical Lean Practices (TLP) berpengaruh positif dan signifikan terhadap Operational Performance (OP). Demikian pula, Human Lean Practices (HLP) juga terbukti berpengaruh positif dan signifikan terhadap Operational Performance (OP). Dengan nilai R-Square sebesar 0,455 menunjukkan bahwa kombinasi TLP dan HLP mampu menjelaskan 45,5% variasi kinerja operasional UMKM, sementara sisanya dipengaruhi oleh faktor lain di luar model penelitian. Temuan ini menegaskan bahwa penerapan praktik lean, baik yang bersifat teknis maupun berbasis sumber daya manusia, berperan penting dalam meningkatkan kinerja operasional UMKM.
