Determining COD and BOD Levels in Oil Palm Industry Liquid Waste: Meeting Environmental Standards

Introduction

The oil palm industry is one of the largest contributors to the global economy, with Indonesia and Malaysia being the top producers of palm oil. However, the industry's liquid waste poses a significant threat to the environment if not managed properly. The Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels in the liquid waste of the oil palm industry are critical parameters in assessing water quality. In this study, we aimed to determine the levels of COD and BOD in the liquid waste of the oil palm industry and evaluate whether it meets the environmental standards set by the government.

Background

The oil palm industry generates a significant amount of liquid waste, which contains high levels of organic substances. If not treated properly, this waste can cause environmental pollution, including the depletion of dissolved oxygen levels in water, which can have a negative impact on the lives of water organisms. The COD and BOD levels in the liquid waste of the oil palm industry are influenced by several factors, including the production process, types of raw materials, and waste treatment system.

Methodology

This study used the titration method to determine the BOD levels in the liquid waste of the oil palm industry, while the spectrophotometry method was used to determine the COD levels. The results showed that the BOD level of the oil palm industry liquid waste was 88.9 mg/L, while the COD content was 140.9 mg/L.

Results

The results of the analysis showed that the BOD and COD levels in the oil palm industry liquid waste were examined Meeting the standard set for the disposal of the water body. That is, the waste is safe to be discharged into the environment without causing significant pollution. According to the Decree of the Minister of Environment Number KEP-51/MENLH/10/1995, the maximum limit for BOD levels in the liquid waste of the oil palm industry is 100 mg/L, while the maximum limit of the COD level is 350 mg/L.

Importance of Measuring COD and BOD Levels

COD and BOD are important parameters in assessing water quality. COD measures the amount of oxygen needed to oxidize all organic substances in water, both those that can be broken down biologically and not. BOD measures the amount of oxygen needed by microorganisms to decompose organic substances that can be broken down biologically in water. The higher the COD and BOD levels, the more oxygen needed to decompose organic substances in the water. This can cause a decrease in dissolved oxygen levels in water, which has a negative impact on the lives of water organisms.

Factors Affecting COD and BOD Levels in the Palm Oil Industry Liquid Waste

COD and BOD levels in the liquid waste of the palm oil industry are influenced by several factors, including:

Production Process: Types of production processes, the amount of raw material used, and the efficiency of the waste treatment process all affect COD and BOD levels. Types of raw materials: Levels of organic substances in palm oil raw materials, such as palm fruit and palm oil, affect the amount of oxygen needed to break down. Waste treatment system: Efficiency of waste treatment systems in removing organic substances also determines COD and BOD levels.

Conclusion

The results showed that the oil palm industry liquid waste meets the disposal standards to the water body. Nevertheless, regular monitoring and analysis remain important to ensure that the quality of the oil palm industry liquid waste is maintained and does not cause environmental pollution. In addition, the palm oil industry needs to continue to improve the efficiency of its waste treatment system and apply environmentally friendly technology to minimize the impact of waste on the environment.

Recommendations

Based on the findings of this study, the following recommendations are made:

  • The palm oil industry should continue to improve the efficiency of its waste treatment system to minimize the impact of waste on the environment.
  • The industry should apply environmentally friendly technology to reduce the levels of COD and BOD in the liquid waste.
  • Regular monitoring and analysis of the liquid waste should be conducted to ensure that the quality of the waste is maintained and does not cause environmental pollution.
  • The government should establish stricter regulations and standards for the disposal of liquid waste from the palm oil industry to protect the environment.

Limitations of the Study

This study has several limitations, including:

  • The study only analyzed the COD and BOD levels in the liquid waste of the oil palm industry and did not consider other parameters that may affect water quality.
  • The study only considered the production process, types of raw materials, and waste treatment system as factors affecting COD and BOD levels, and did not consider other factors that may influence the levels of these parameters.
  • The study only analyzed the liquid waste from one oil palm industry and did not consider the liquid waste from other industries.

Future Research Directions

Future research should focus on:

  • Conducting a comprehensive analysis of the liquid waste from the oil palm industry, including other parameters that may affect water quality.
  • Considering other factors that may influence the levels of COD and BOD, such as the type of waste treatment system used and the efficiency of the waste treatment process.
  • Analyzing the liquid waste from other industries to determine whether the findings of this study are applicable to other industries.
