Abstract
Indonesia faces environmental challenges due to the increasing exploitation of natural resources and industrial emissions. This study aims to design an environmental impact mitigation strategy in the furniture industry using the Life Cycle Assessment (LCA) method, with a case study of UD Putra Bali. The analysis includes the Life Cycle Inventory (LCI), Life Cycle Impact Assessment (LCIA), and Life Cycle Interpretation to identify the greatest impacts and develop recommendations for improvement. The results of the study indicate that the life cycle of wooden door products produces an environmental impact of 13.1 kPt. The stage with the greatest impact is the finishing process, especially in the human toxicity water category of 11.3 kPt, due to thinner-based paint. In addition, the delivery of finished products contributes to the global warming category of 0.0539 kPt, which is caused by the use of vehicles with high emission specifications and inefficient delivery routes. Recommendations for improvement include the implementation of cleaner production, namely replacing thinner-based paint with more environmentally friendly water-based paint and optimizing delivery routes using the saving matrix nearest insert method to reduce the total distance traveled and transportation emissions. After the implementation of the mitigation strategy, the environmental impact of the finishing process decreased to 10.3 kPt, while the impact of the finished product delivery decreased to 0.0526 kPt. This study shows that the application of LCA can identify the main sources of environmental impacts and generate data-based improvement strategies. The implementation of this strategy is expected to enhance the sustainability of the furniture industry and reduce the production process's environmental footprint.

Abstract
In this research, a new bi-objective routing problem is developed in which a conventional vehicle routing problem with time windows (VRPTW) is considered with environmental impacts and heterogeneous vehicles. In this problem, minimizing the fuel consumption (liter) as well as the length of the routes (meter) are the main objectives. Therefore, a mathematical bi-objective model is solved to create Pareto's solutions. The objectives of the proposed mathematical model are to minimize the sum of distance cost as well as fuel consumption and Co2 emission. Then, the proposed Mixed-Integer Linear Program (MILP) is solved using the ε-constraint approach Furthermore, numerical tests performed to quantify the benefits of using a comprehensive goal function with two different objectives. Managerial insights and sensitivity analysis are also performed to show how different parameters of the problem affect the computational speed and the solutions’ quality.

Abstract
The main objective of this study is to determine factors influencing the adoption and impact of online social networks use in terms of performance among students within public universities in Abu Dhabi. Although various limitations exist, the findings have been encouraging, as it has managed to shed some lights on new variables affecting the use of online social networks. This study proposed an extended model of the Unified Theory of Acceptance & use of Technology (UTAUT) and found that five variables play an important role to determine the performance impact of online social networks namely performance expectancy, effort expectancy, social influence, facilitating conditions, and actual usage, in addition to the significant moderation role that service quality plays in the model which was significant on two relationships and insignificant in the remaining two. The findings of this study can provide policymakers with important insights on how to more successfully incorporate online social networks to improve students’ performance and public university services, and how to encourage the management to ensure that students are more likely to utilize new technologies and thereby enabling better learning outcome, wider reach of services, gives students more control over their daily tasks and enhances their performance.
