Hazardous waste management poses significant challenges due to its potential risks to human health and the environment. This study develops a multi-objective decision model for hazardous waste management, focusing on minimizing both total cost and transportation risk. The model integrates various aspects of hazardous waste handling, including facility location selection, optimal transportation routing, recycling of residual waste, and capacity constraints of each facility. By utilizing a mixed-integer programming approach, the model accounts for different types of hazardous waste, their residu

The performance of lecturers is a critical determinant of the quality of education and the success of postgraduate programs in higher education institutions. This study aims to examine the influence of work environment, competence, and job satisfaction on the performance of lecturers teaching in Master's and Doctoral programs at private universities in Medan, Indonesia. Using a quantitative approach and a Structural Equation Modeling (SEM) methodology, data were collected from 255 lecturers across various private universities that offer postgraduate programs. The results reveal that both compe

Software-Defined Wireless Sensor Networking (SDWSN) is termed a raising network structure that became more important to the Internet of Things (IoT). In this network structure, the control planes effectively manage the sensor plane. Due to these kinds of separation, the management of networks became easier and also their efficacies are enhanced in the self-motivated atmosphere. The common issue presented in the sensor atmosphere is minimal life in the network devices inspired by the maximal level of energy consumption rate. The current work proposes a system design that aims to improve efficie

Within the classifications of SMEs, the so-called retail or commercial SMEs are located, which largely drive Peruvian national consumption. It must be taken into account that each percentage point increase in the growth of per capita consumption It is associated with the level of employment and the competitiveness of companies, that is, 1% growth in per capita consumption generates a 2% reduction in poverty; therefore, boosting consumption is important for the growth of not only the country; In this context, commercial SMEs take on an essential relevance since, as a way to generate greater

This descriptive quantitative study delves into the intricate dynamics between Job crafting, work engagement, transformational leadership, and the moderate role of meaningful work in an organizational context. In addition, this study investigates how the moderating effect of meaningful work affects the impact of work engagement and transformational leadership on job craft. Data was collected through surveys provided to diverse employees across industries. Quantitative measures to assess job crafting, level of job engagement, transformational leadership, and presence of meaningful work experi
