Analysis of Brewery Waste and Impact on the Environment in Hera, Timor-Leste

The beer beverage industry is currently growing very rapidly, and because of these activities, the beverage industry can produce waste on a large or small scale. The results of small-scale waste can decompose naturally, but large-scale waste can be harmful to the environment. Therefore, large-scale factory waste can produce very dangerous waste for the environment and its components. The brewery is the only brewery in the country of Timor-Leste. With the idea that the brewery in Hera, Timor-Leste, has processed its waste properly and is safe for the environment, it is necessary to prove that the liquid waste of the beer beverage factory does not hurt the environment. This study aims to analyze the quality of the beer factory's liquid waste and the quality of the water where the beer beverage liquid waste is disposed of. The method used in this study is the intentional sampling method or also known as judgment sampling. Sample analysis was conducted at the Forestry and Environment Laboratory of Bali Province, Indonesia, from December 14, 2023, to December 23, 2023. From the results of the laboratory tests, it can be concluded that the liquid waste from the Hera brewery, Timor-Leste, has a normal pH, high turbidity, low DO levels, and high BOD levels. This harms the marine environment where the liquid waste is disposed of, because it can cause the death of marine organisms, disrupt the balance of the marine ecosystem, and cause irreversible damage. Therefore, the Timor-Leste Government must conduct regular waste inspections and establish regulations on the maximum concentration of pollutants contained in brewery waste that can be discharged into the environment, as explained in the regulations of the Minister of Environment and Forestry of the Republic of Indonesia. In short, breweries must review their liquid waste treatment process before discharging it into the environment so that the waste produced does not comply with the laws and regulations that must be established. And it is suggested to the Government and the Timor-Leste Environmental Nacional Agency or ANLA to always conduct periodic field inspections to check the quality of beer liquid waste on the environmental impact so as not to damage the water and soil environment and all living things.
