# Multi-objective integer programming model for waste management in the palm oil industry

The palm oil industry in Indonesia is a vital agro-industrial sector, significantly contributing to the national economy. From the processing of palm crude oil, two main products are produced, namely CPO (Crude Palm Oil) and CPKO (Crude Palm Kernel Oil), each of which only covers 22.8% of the total materials processed. Most of this process produces waste, including wastewater that is rich in organic content, large amounts of solid waste, and air pollution. This problem not only threatens the environment, but also poses a risk for the community around the factory.

The Need for Innovative Waste Management Solutions

In facing these challenges, an innovative approach is needed for waste management. The palm oil industry is one of the largest contributors to deforestation and habitat destruction in Indonesia, and the production of palm oil is also a significant source of greenhouse gas emissions. The industry's waste management practices are often inadequate, leading to environmental degradation and health problems for local communities. Therefore, it is essential to develop effective waste management strategies that balance economic, social, and environmental considerations.

Multi-objective Integer Programming Model for Waste Management

One of the solutions submitted in this dissertation is the use of multi-objective integer programming models (Momilp) specifically designed to improve waste management in the palm oil industry. This model aims to optimize the production planning process by taking into account three main aspects: Environmental Impact (EI), risk reduction for the surrounding community (PR), and cost efficiency. The model uses a mathematical programming approach to optimize the production planning process, taking into account the conflicting objectives of reducing waste, minimizing resource use, and reducing operational costs.

Benefits of Multi-objective Integer Programming Model

This multi-objective integer programming model allows decision makers to conduct a more holistic and integrated analysis in waste planning and management. Taking into account various objectives, such as reducing the waste produced, minimizing the use of resources, and reducing operational costs, this model can provide a balanced and sustainable solution. The model can also be used to simulate various scenarios, allowing stakeholders to evaluate the implications of the decisions taken.

Advantages of Multi-objective Integer Programming

One of the main advantages of multi-objective integer programming is its ability to provide trade-off between various conflicting criteria. For example, increasing production efficiency can lead to increased waste, so a smart strategy is needed to balance the two. This model can also be applied to simulate various scenarios, allowing stakeholders to evaluate the implications of the decisions taken.

Application of Multi-objective Integer Programming Model

The application of this model is expected to help the palm oil industry to adapt to increasingly stringent environmental regulations, and meet market demands that are increasingly concerned with the issue of sustainability. Thus, it is not only environmental issues that can be minimized, but also industrial reputation will be better in the eyes of the community and other stakeholders.

Role of Information Technology and Data-based Decision Making

In addition, the application of information technology and data-based decision making systems in this model can increase the accuracy and speed of analysis. This is important so that the industry can quickly respond to changes in market conditions and regulations, as well as minimize the negative impacts of the waste produced.

Conclusion

Overall, the application of multi-objective integer programming models in waste management in the oil palm crude oil industry shows a great potential to create a balance between production needs and environmental sustainability. With this systematic and innovative approach, it is expected that industry can be more responsible and contribute to sustainable economic development in Indonesia.
