Abstract

In 2010, Indonesia ranked fourth in terms of waste generation. As a result, the waste sector is estimated to potentially contribute 296 Mt CO2 eq (10.32%) of total greenhouse gas (GHG) emissions by 2030, with a projected annual growth rate of 6.3% using the business-as-usual (BAU) projection from 2010 to 2030. Around seventy per cent of all waste is organic, making household waste one of the main sources of urban waste. This study was conducted at the Benowo Landfill in the city of Surabaya. The SNI 19-3964-1994 method was used to sample the composition and generation of waste at the landfill. Waste generation projections were made up to 2030, taking into account population growth. This study compares methane gas emissions from three scenarios: Scenario 1, direct landfilling of waste; Scenario 2, waste reduction through composting and 3R processing; and Scenario 3, waste processing at the landfill through gasification. Based on inventory calculations using the 2006 IPCC guidelines, the landfill scenario produces the highest greenhouse gas emissions (CO2 and CH4), with the highest CH4 emissions and the lowest CO2 emissions. The gasification scenario has the highest CO2 emissions and the lowest CH4 emissions due to the use of aerobic systems and combustion.

Abstract

With the increasing use of various types of single-use plastics, plastic waste is piling up in landfills. The degradation process of plastic causes plastic waste to become small pieces, namely microplastics, which will be absorbed into leachate channels and disposed into the environment if not treated. The entry of microplastics into the ecosystem, especially in the food sources we consume, will have a harmful impact on human health, such as cancer, respiratory disorders, and more. Subsurface Flow Constructed Wetland (SSF-CW) treatment is used to reduce the microplastic content in leachate. Microplastics were found in every sample, but SSF-CW with plants resulted in a better reduction of microplastics than without plants, which was able to reduce 72% of the microplastics from the initial total in the influent. The forms of microplastics found were fibers and filaments, with fiber-shaped microplastics being the dominant form found. The sizes of the microplastics found in this study ranged from 5 mm - 0.1 mm, and in the two samples, most microplastics were found to be 0.5 mm - 0.1 mm. Thus, leachate treatment with constructed wetlands can reduce the microplastic content in leachate, and the plants play an active role in retention, physical filtration and adsorption of microplastics.

Abstract

In general, laundry businesses use detergent rather than soap to wash clothes because detergent contains surfactants that are more effective at removing dirt. This washing process produces waste that is usually disposed of directly into the environment. The indiscriminate disposal of laundry waste can cause environmental pollution because it contains pollutants, such as chemical oxygen demand (COD) and surfactants, that exceed established quality standards. The purpose of this research was to test the effectiveness of water bamboo plants in reducing COD and MBAS levels in laundry waste. This phytoremediation method utilizes microorganisms (rhizosphere microbes) living in the root system and planting media. These microorganisms decompose organic and inorganic materials in wastewater into simpler compounds, which are then used as nutrients by the plants. The most effective configuration for reducing COD and surfactant levels in laundry waste is 15 water bamboo plants with a residence time of three days. However, COD levels are still above the quality standard while surfactant levels are below it.

Abstract

The animal feed ration industry in South Kalimantan Province produces domestic liquid waste from supporting activities with quite high levels of pollutants. The waste is processed using a Wastewater Treatment Plant (WWTP) and reused to reduce environmental impacts. This study aims to examine the efficiency of utilizing domestic waste as an alternative water source for watering Green Open Spaces (GOS) in industrial areas. The research method used is descriptive-quantitative based on secondary data. Based on the results of wastewater quality measurements at the WWTP outlet,it shows that domestic waste has met the quality standards according to the Minister of Environment and Forestry Regulation P.68 of 2016 and PP No.22 of 2021 for watering purposes. The animal feed ration industry produces domestic waste of 15.5m³/day with a WWTP capacity of 20m³/day and a planned GOS area of ​​8,715.15m². There are two scenarios for wastewater utilization, namely in the dry season with an efficiency of 40.65% and the rainy season with an efficiency of 81.31% of the total industrial raw water needs. These results indicate that domestic waste in the animal feed ration industry has the potential to be an alternative water source that is environmentally friendly and supports sustainable water management.

Abstract

Wastewater generated from poultry slaughterhouses generally contains high levels of organic matter and ammonia, which can contaminate aquatic environments if not properly treated. The high organic content contributes to elevated COD levels, while ammonia can be toxic to aquatic organisms. This study was conducted to evaluate the performance of a biofilter system with intermittent aeration (anoxic–oxic combination) using tree fern board and bioring media in reducing COD and NH₃-N concentrations. The tested aeration durations included 3 hours (1 hour anoxic, 2 hours oxic), 6 hours (2 hours anoxic, 4 hours oxic), 9 hours (3 hours anoxic, 6 hours oxic), and 12 hours (4 hours anoxic, 8 hours oxic). The experimental results showed that the bioring medium exhibited better performance than the tree fern board, with the optimum condition achieved at a 12-hour hydraulic retention time, resulting in COD and NH₃-N reductions of 93.41% and 88.21%, respectively. Overall, the findings indicate that a bioring-based biofilter with intermittent aeration has strong potential as an effective and environmentally friendly alternative technology for treating poultry slaughterhouse wastewater.

Abstract

Slaughterhouse wastewater contains high levels of organic matter and nitrogen, which can potentially pollute the environment if not properly treated. This study aims to analyze the effectiveness of the Moving Bed Biofilm Reactor (MBBR) system with intermittent aeration using pumice stone media in reducing Chemical Oxygen Demand (COD) and ammonia (NH₃-N) concentrations. The tested variables included media filling ratios (25%, 35%, and 45%) and hydraulic retention times (4, 6, and 8 hours) with balanced oxic–anoxic cycles. The results showed that increasing the media ratio and retention time significantly improved pollutant removal efficiency. The best performance was achieved with 45% media and an 8-hour retention time, resulting in COD and NH₃-N removal efficiencies of 87% and 82.8%, respectively. The pumice stone media effectively supported biofilm growth, which played a key role in the nitrification–denitrification processes. The intermittent MBBR technology with pumice media proved to be efficient, economical, and environmentally friendly for the treatment of slaughterhouse wastewater.

Abstract

Tofu wastewater is a liquid waste with high organic content that has the potential to be recycled. This study aims to analyze the effect of substrate composition and fermentation time using EM4 starter on the abundance of Lactobacillus sp. as a key parameter of probiotic quality. The study used a Completely Randomized Design (CRD) with four composition treatments: P1 (30% TWW : 30% water : 40% EM4), P2 (40% TWW : 20% water : 40% EM4), P3 (50% TWW : 10% water : 40% EM4), and P4 (60% TWW : 0% water : 40% EM4). Fermentation was observed for 18 days. The results showed that composition and fermentation time significantly affected bacterial abundance. The highest abundance was achieved in P4 on day 14 (7.0 × 10⁶ CFU/mL). However, the most efficient composition was P1, which produced a high abundance of Lactobacillus sp. (4.1 × 10⁶ CFU/mL) and successfully reduced BOD₅ levels to 108.45 mg/L, below the quality standard. The optimal fermentation time was 14 days, after which the population declined. It was concluded that the fermentation of tofu wastewater with the right composition and time can produce qualified probiotics while reducing environmental pollution.
