Abstract

The rapid growth of the laundry industry in Indonesia, recorded in 2021 there were more than 30,000 laundries spread throughout Indonesia with a business growth of 15-20% per year (Bisnis et al, 2021) the increased laundry industry means more wastewater will be produced. If it is not treated properly before being discharged into water bodies, it can pollute water bodies and the ecosystems inside. One of the processing methods is the Moving Bed Biofilm Reactor (MBBR) which is a biological method by utilizing microorganisms to form a biofilms and stick to carrier media and then move dynamically so that contact occurs between waste and microorganisms effectively which can degrade pollutants in laundry waste, the more bacteria added and the longer the contact time, the more pollutants will be degraded. In this study, variations in the addition of Pseudomonas aeruginosa bacteria were carried out by 0%, 3%, 5%, 7% and 10% with contact times of 7 hours, 14 hours, 21 hours and 28 hours to degrade COD, phosphate and detergent parameters in laundry wastewater. The greatest removal efficiency was obtained at the addition of 10% bacteria and a contact time of 28 hours, namely 84% COD, 96% detergent and 74% phosphate. The number of colonies in the biofilm with the addition of 0% was 101,000 CFU/mL, 3% was 110,000 CFU/mL, 5% was 184,000 CFU/mL, 7% was 234,000 CFU/mL and 10% was 338,000 CFU/mL.

Abstract

The increase in population and urbanisation has led to to an increased volume of domestic wastewater containing pollutants such as organic matter and nitrogen, which pose a significant risk to the environment and aquatic ecosystems. This study aims to evaluate the effectiveness of a combined anoxic–oxic process integrated with Pistia stratiotes (water lettuce). constructed wetland system for removing Chemical Oxygen Demand (COD) and total nitrogen from domestic wastewater. The experiment was conducted using wastewater concentrations of 20%, 40% and 60%, with a retention time of five days. The system operated under anoxic conditions for the first two days, This was followed by oxic conditions with aeration from days three to five. The Results showed that the highest removal efficiency was achieved at a wastewater concentration of 20%. wastewater concentration and a five-day retention time. This resulted in COD and total nitrogen removal efficiencies of 63.16% and 70%, respectively. These findings suggest that the anoxic–oxic system combined with Pistia stratiotes is effective in enhancing the treatment performance of domestic wastewater. This is particularly evident at lower concentrations and optimal retention times.

Abstract

The electroplating industry produces liquid waste containing dissolved heavy metals, such as copper and nickel. If this waste is not managed properly, it has the potential to cause environmental pollution. One method that can be used to address this issue, particularly with regard to the heavy metal parameters Cu and Ni, is phytoremediation. Phytoremediation utilises plants to remove pollutants from the environment. Plants that can absorb heavy metals in this way include napier grass (Pennisetum purpureum) and speargrass (Imperata cylindrica). This study aims to determine the ability of these two plant species to absorb and remove heavy metals (Cu and Ni) from electroplating waste. The research was conducted using a batch system with variations in sampling time on days 7, 14, 21, 28 and 35. Napier grass produced the best results on day 21, with reduction efficiencies of 85.7% for Cu and 82.5% for Ni. Meanwhile, speargrass produced the most optimal results on day 35, reducing Cu by 89.2% and Ni by 87.3%. Based on these results, speargrass proved to be more effective than napier grass in reducing the levels of the heavy metals copper (Cu) and nickel (Ni) in electroplating waste.

Abstract

Composting is one way of managing organic waste from traditional markets. However, this process takes a long time, so bioactivators are needed to speed up decomposition. Leachate and bamboo shoot MOL (local microorganisms) can serve as bioactivators as they contain the necessary microorganisms and nutrients. This study examines the effect of adding leachate and bamboo shoot MOL to compost organic waste from traditional markets. The composting process used vegetable waste, coconut pulp and sawdust as raw materials, with 1-litre doses of each bioactivator variation. The results showed that the bamboo shoot MOL and the leachate-MOL combination treatments reached standard levels of C, N, P, K and the C/N ratio faster than the control treatment and the leachate-only treatment. The C/N ratios were as follows: control (19.91); leachate (18.15); bamboo shoot MOL (15.41); and leachate-MOL combination (17.73). All of these met the compost quality standard based on SNI 19-7030-2004. Physical changes in the compost occurred faster in the bamboo shoot MOL treatment (day 15) and the combination treatment (day 18) than in the leachate-only treatment (day 21) and the control treatment (day 24). Based on these results, bamboo shoot MOL was proven to be the most effective treatment for accelerating the composting process and improving the quality of the final compost.

Abstract

Rapid industrial growth increases the production of hazardous and toxic waste (LB3), which, if not managed properly, can pose a serious risk to human health and the environment. This study analyses the risks associated with the incineration of hazardous waste at PT XYZ, using the Hazard Identification, Risk Assessment and Risk Control (HIRARC) approach based on the AS/NZS 4360:2004 standard. Hazard identification is conducted via Job Safety Analysis (JSA), while risk assessment considers likelihood and severity. The results show that the infectious waste feeding process and combustion emissions pose the greatest risk (high and very high), with potential consequences including exposure to chronic diseases and environmental pollution. Risk control is achieved by providing personal protective equipment (PPE), monitoring flue gas emissions and managing incinerator residues in accordance with regulations. This study highlights the importance of implementing strict risk management measures and technological innovations to mitigate the negative impacts of hazardous waste incineration.

Abstract

Jalan Raya Kertajaya Indah and Manyar Kertoarjo are among the main road corridors in Surabaya City, heavily trafficked by various types of motorized vehicles, ranging from light to heavy-duty vehicles. The high traffic volume, especially during peak hours, causes congestion that significantly contributes to air pollution, particularly carbon dioxide (CO₂) emissions. This study aims to assess whether the CO₂ emissions produced by motor vehicles along the corridor can be absorbed by the existing roadside greenbelt vegetation. The analysis was conducted by estimating CO₂ emissions using the Intergovernmental Panel on Climate Change (IPCC, 2006) method, based on traffic counting data and specific vehicle emission factors. Furthermore, the carbon absorption capacity of the vegetation was calculated using a non-destructive sampling method by measuring tree diameter at breast height (DBH) and applying appropriate allometric equations. The results show that the total carbon dioxide emissions generated by motor vehicles traveling through Jalan Raya Kertajaya Indah and Manyar Kertoarjo in one year amount to 3,017,256.95 kg CO₂/year. Meanwhile, the total carbon absorption capacity of the greenbelt vegetation along these roads reaches 4,825,576.90 kg CO₂/year. It can thus be concluded that the carbon absorption capacity of the roadside vegetation is sufficient to offset, and even exceed, the annual CO₂ emissions generated by motor vehicle activities in this corridor.
