Simultaneous products distribution and items retrieval in an integrated forward/reverse logistics network faces a complex freight-scheduling problem due to the constraints involved. In the high to intermediate network level, the problem usually exists in the form of single stop transportation. To reach a higher level of performances, there is a need to model and optimize the freight schedule. This research proposes a model to optimize a freight-scheduling problem. The proposed model of this paper based on Non-dominated sorting genetic algorithm-II is formulated to solve a conflicting bi-objective optimization and optimizes a real-world case study. A solution from the model demonstrates the solution interpretation in the form of delivery schedule, distribution as well as retrieval route, and vehicle assignment. Moreover, the solutions are also comparable to some current manual solution by its similarity. The results show that the model was capable of generating feasible solutions while satisfying all of its constraints.

Each company is recommended to implement this variable as competitive weapon in order to get a better operational performance and competitiveness as well.

This study aims to describe the collaboration of stakeholder roles and analyzes the influence of government, Micro & Small businesses and workers to improve the performance of Occupational Health and Safety (OHS) officers in community health center. The study is a survey with a cross-sectional design to measure the influence of stakeholders' role on the performance of occupational health efforts. The study sample was 80 people, namely all OHS officers from the community health center (CHC) in the city of Medan. The independent variables in this study are the role of government (X1), the role of micro and small business (X2), the role of the workers (X3) and the performance of OHS officers is the dependent variable. Data collection is perfomed using a questionnaire that has been validated with interval scales 1 - 5. Hypothesis testing is based on using structural equation modeling path analysis and analysis is performed using PLS-SEM, Smart PLS 3.0. Direct test results show that the government has not played a significant role in Micro & Small Business and the role of workers. The government only plays a significant role in the performance of OHS officers. Micro & Small businesses significantly influence workers' role, but it has not significantly affected OHS officers' performance. The role of workers significantly influences the performance of OHS officers. Test results indirectly show the critical role of collaboration between stakeholders. Although it has not shown a significant effect, there is an increase in the significant value on the performance of officers. The finding confirms the need for seriousness and the importance of collaboration among stakeholders. The research needs to be expanded by involving all OHS officers up to sub-health centers, and other districts/cities with the same characteristics. The study has only investigated at community health center. Policy recommendations are given for managing an integrated occupational health service program in community health center involving all stakeholders in Medan.

The most significant impacts on the environment and society of corporate operations occur in the supply chain. Environmental impacts occur at different stages of the environmental life cycle and relate to the extraction of raw materials from the earth, the processing and manufacturing of building materials, the construction process, operation or use, maintenance and repair, repair and eventual disposal or reuse of materials. Environmental phenomena of climate change or global warming are the result of human practice. Global warming causes an increase in ocean temperatures and surface of the book, causing melting of polar ice caps and rising sea levels. Another phenomenon of waste and sewage problems has become a national and international problem. Every supply chain activity in a series of production activities has an impact on the environment. Supply chains can have different organizational structures that reflect business relationships or the level of collaboration between chain companies. This study examines the relationship of Life Cycle Assessment (LCA) with Environment Supply Chain Management (ESCM) and Sustainability Supply Chain in Manufacture in Indonesia.
