Abstract

Industrial organizations are currently operating in increasingly complex environments characterized by high levels of uncertainty, rapid technological advancement, and growing sustainability pressures. Under these conditions, improvements in industrial performance can no longer be effectively achieved through isolated technical or managerial approaches. This study aims to develop a systems-based framework that integrates operations engineering, management systems, and human resource management (HRM) to support sustainable industrial performance using a System Dynamics approach. The research methodology is systematically structured, encompassing problem formulation, system boundary definition, causal loop diagram development, stock-flow modeling, model validation, and policy scenario simulation. Simulation results indicate that fragmented strategies generate only limited short-term performance improvements. In the baseline scenario, the Sustainable Industrial Performance Index increases from 70.0 to 70.9 within a two-month period. An HRM-focused strategy raises the index to 71.9, while an operations-oriented strategy achieves a higher improvement, reaching 72.8. The most substantial improvement is observed under an integrated policy scenario that combines HRM investment, enhanced operational reliability, and managerial alignment, resulting in an index increase to 73.8 over the same period. These findings confirm that integrated policies create synergistic effects and highlight the critical role of feedback mechanisms and time delays in shaping industrial performance dynamics. This study concludes that sustainable industrial performance emerges from the dynamic interaction among technical, managerial, and human subsystems and provides both theoretical contributions to industrial systems modeling and practical value as a decision-support foundation for strategic policymaking.

Abstract

Water hyacinth is an aquatic weed whose life cycle is floating in waters or raising roots in mud in shallow waters. The purpose of this water hyacinth itself is to be able to minimize abandoned plant gardens on Lake Toba, so that water hyacinth in the area grows to be more useful, both for the environment and for society. This study uses literature studies, the object of this research is information systems and previous research related to the phenomena discussed, this aims to develop solutions and related problems. The results showed that organic fertilizer from water hyacinth has the potential to improve the household and community economy. This organic fertilizer can also help reduce the population of wild water hyacinth plants in Lake Toba. Processing methods for organic fertilizer from water hyacinth include picking, grinding, microdeck sowing, and decomposition. Implementation of this activity can provide benefits such as reducing the use of chemical fertilizers and increasing soil fertility. Liquid organic fertilizer from water hyacinth contains important nutrients such as nitrogen which can help plant growth. The use of organic fertilizer from water hyacinth can also contribute significantly to the length of plant cobs. In addition, composting water hyacinth can produce organic fertilizers that can be used by farmers as an alternative to chemical fertilizers. The use of water hyacinth as organic fertilizer has the potential to improve the economy of the people in the Lake Toba Region. However, this application also faces certain constraints and challenges. Therefore, policy recommendations and actions need to be taken to facilitate the sustainable use of water hyacinth organic fertilizer and contribute to improving the economy of the people in the Lake Toba Region

Abstract

Palm oil waste is a waste or by-product produced during the palm oil processing process. During the palm oil extraction process, some parts of the oil palm fruit are not used and are considered waste. The use of empty coconut bunches as agricultural organic fertilizer is an interesting topic in the field of sustainable agriculture. Empty coconut bunches are waste generated from the palm oil industry, and can be converted into organic fertilizer which is beneficial for increasing soil fertility and crop productivity. The use of empty coconut bunches as organic fertilizer also has environmental benefits. By processing this waste into fertilizer, empty coconut bunch waste can be reduced, thereby reducing its negative impact on the environment in North Labuhan Batu Regency. In addition, the use of organic fertilizers reduces dependence on chemical fertilizers that can pollute soil and water. This research uses literature studies, the object in this study is information systems and previous research related to the phenomena discussed, this aims to develop solutions and related problems. The results showed that organic fertilizer from empty coconut bunches has reduced environmental pollution of greenhouse gases. This organic fertilizer helps reduce fertilization costs from farmers' dependence on chemicals. In addition, EFB also contains a number of important nutrients such as nitrogen (N), phosphorus (P), potassium (K) and magnesium (Mg) which can delight the soil. Organic fertilizers derived from EFB have an additional advantage, namely releasing nutrients slowly into the soil thereby reducing the risk of environmental pollution and increasing the efficiency of nutrient use

Abstract

This study investigates the structural relationships between Digital Transformation, Human Resource Development, and Operational Performance using the Partial Least Squares-Structural Equation Modeling (PLS-SEM) approach. The research aims to examine how digital initiatives and human resource capability development contribute to improving operational performance in organizations. Data were collected from 200 respondents involved in operational and digital transformation activities. The results indicate that Digital Transformation significantly enhances Operational Performance by improving process efficiency, flexibility, and productivity through the integration of digital technologies and data-driven decision systems. Human Resource Development also has a significant positive effect on Operational Performance by strengthening employee competencies, training effectiveness, and learning culture. In addition, Human Resource Development significantly influences Digital Transformation, indicating that employee readiness and capability are critical factors for successful digital implementation. The structural model demonstrates strong explanatory power and predictive relevance, indicating that the integration of technological transformation and human capital development plays an important role in improving operational performance. These findings provide managerial insights for organizations seeking to align digital transformation strategies with human resource development initiatives to achieve sustainable operational improvements.
