Abstract

This study presents a techno-economic analysis of the development of integrated waste processing installations, focusing on plastic waste management. The research evaluated a 20-year business feasibility using various financial indicators, including gross profit margin (GPM), internal rate of return (IRR), payback period (PBP), and net present value (NPV). Additionally, this study includes a literature review supported by bibliometric analysis to contextualize current trends in waste processing innovation and economic sustainability. The findings indicated that the project was technically viable and economically promising. The PBP analysis revealed that the investment became profitable after approximately three years, suggesting that the project met acceptable profitability benchmarks. The novelty of this research lies in its application of techno-economic analysis to assess both the technical feasibility and the economic value of waste management initiatives. Furthermore, this study contributes to the Sustainable Development Goals (SDGs), particularly by promoting responsible consumption and production (SDG 12) and fostering sustainable urban environments (SDG 11).

Abstract

Workload management is a critical issue in the banking sector due to high service intensity and time pressure faced by frontline employees. An imbalance between job demands and employee capacity may lead to work fatigue and reduced service quality. This study aims to analyze employee workload and identify workload indicators that require managerial attention in order to support effective human resource management. A qualitative descriptive approach was employed, with data collected through direct observation, in-depth interviews, and documentation. Employee workload was analyzed using five indicators: task quantity, task complexity, time required, task frequency, and task variability. The findings indicate that workload conditions are generally appropriate in terms of task quantity, task complexity, and task variability, reflecting alignment with job descriptions and existing work systems. However, the indicators of time required and task frequency reveal relatively high workload levels, particularly for customer service and teller positions, due to limited staffing and fluctuating customer volume. These conditions potentially increase work fatigue and reduce service effectiveness. Therefore, this study highlights the importance of evaluating workload distribution and optimizing human resource planning to ensure a balance between service demands and employee capacity in the banking sector.

Abstract

The work environment plays a strategic role in supporting employee effectiveness and organizational sustainability, particularly in creative industry enterprises. This study addresses the main problem of suboptimal work environment conditions at PT Anugrah Wijaya Maskot, which are suspected to affect employee performance and the stability of company revenue. The purpose of this research is to analyze the physical and non-physical work environment conditions and their implications for employee work effectiveness. This study employed a descriptive qualitative approach. Data were collected through direct observation, in-depth interviews, discussions with company personnel, and analysis of internal company documents during fieldwork activities. The findings reveal that the physical work environment has not been optimally managed, especially regarding the availability and feasibility of production facilities, temperature control, and air circulation, which tend to reduce employee comfort and work concentration. Conversely, the non-physical work environment shows relatively favorable conditions, characterized by harmonious working relationships, effective communication, and a supportive social climate among employees. This imbalance between physical and non-physical work environment aspects contributes to fluctuations in operational performance, as reflected in the company’s revenue achievement throughout 2024. These findings highlight the importance of integrated work environment management as a strategic effort to enhance employee productivity and support sustainable organizational performance.

Penelitian ini bertujuan untuk mengetahui dan menganalisis pengaruh kompensasi dan lingkungan kerja terhadap kepuasan kerja dengan motivasi kerja sebagai variabel intervening pada karyawan PT AMB. Berdasarkan hasil analisis dan pengujian hipotesis, ditemukan bahwa tanggapan karyawan terhadap variabel kompensasi, lingkungan kerja, motivasi kerja, dan kepuasan kerja berada dalam kategori baik. Hasil penelitian menunjukkan bahwa kompensasi dan lingkungan kerja memiliki pengaruh langsung yang positif dan signifikan terhadap motivasi kerja. Selain itu, kompensasi, lingkungan kerja, dan motivasi kerja juga berpengaruh langsung positif dan signifikan terhadap kepuasan kerja. Lebih lanjut, kompensasi dan lingkungan kerja terbukti memiliki pengaruh tidak langsung yang positif dan signifikan terhadap kepuasan kerja melalui motivasi kerja. Temuan ini menegaskan pentingnya peran kompensasi, lingkungan kerja, dan motivasi dalam meningkatkan kepuasan kerja karyawan.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh lingkungan kerja dan kompetensi terhadap kinerja karyawan, dengan kepuasan kerja sebagai variabel intervening, pada PT. Japfa Comfeed Indo Tbk, Unit Farm Parungkuda. Dengan jumlah Sampel 114 karyawan, latar belakang penelitian menunjukkan adanya permasalahan kinerja karyawan yang belum optimal, ditandai oleh tidak tercapainya target produksi dan penurunan nilai kinerja, serta kepuasan kerja yang masih rendah di perusahaan tersebut. Faktor-faktor yang diduga mempengaruhi kinerja adalah lingkungan kerja dan kompetensi, baik secara langsung maupun tidak langsung melalui kepuasan kerja. Penelitian ini menggunakan pendekatan kuantitatif dengan metode analisis jalur (path analysis), uji t, dan uji Sobel untuk menguji hipotesis. Hasil penelitian menunjukkan bahwa lingkungan kerja dan kompetensi berpengaruh langsung dan positif terhadap kepuasan kerja. Lingkungan kerja dan kompetensi juga berpengaruh langsung dan positif terhadap kinerja karyawan. Selain itu, kepuasan kerja berpengaruh langsung dan positif terhadap kinerja karyawan. Hasil uji Sobel mengkonfirmasi bahwa kepuasan kerja secara tidak langsung memediasi pengaruh lingkungan kerja dan kompetensi terhadap kinerja karyawan.
