Abstract

According to Presidential Regulation No. 35 of 2018, which focuses on accelerating the development of waste-to-energy projects, Denpasar City in Bali has been identified as one of the key Indonesian cities for implementing these projects. The daily waste generation in Denpasar City is estimated at 750 tons. The city's sanitation strategy outlines that 20% of this waste will be reduced at its source, while the remaining 80% is managed at the final treatment site. This study employs the Life Cycle Analysis (LCA) approach to evaluate the environmental impacts of traditional landfilling and various thermal waste treatment methods. The findings reveal that gasification (Scenario 2) has the lowest Global Warming Potential (GWP), with 779,759 kg CO2 equivalent emitted, indicating its superiority in reducing greenhouse gases. In contrast, landfilling (Scenario 1) is the least favorable, with a GWP of 2,885,770 kg CO2 equivalent and a significant cancer risk due to hexavalent chromium emissions estimated at 1,634,050 kg equivalent. These results underscore the health and environmental hazards of landfilling. Further, the study delves into each treatment scenario's impact on acidification, eutrophication, global warming potential, and photochemical oxidation.

Abstract

Waste is increasingly recognized not just as an environmental challenge but also as an economic opportunity, particularly in developing countries like Indonesia where it can help alleviate employment shortages. This study explores the dual role of waste as both a tradable commodity driven by industrial demands for raw materials, including primary substances, additives, and Refuse Derived Fuel (RDF), and as a means of reducing environmental impact. This phenomenon is important and interesting because it can have a positive impact both in terms of reducing waste, saving natural resources, and as an economic opportunity for society. This study aims to examine the potential of waste that can be utilized as a resource on the one hand and reduce the potential for pollution on the other. The study used the Material Flow Analysis (MFA) method with the Circular Economy principle and used an action research approach to redesign the waste processing system. The results of this study indicate that the current system only manages 34% of the total waste generation and only 4% can be reused with sales of IDR 97.9 million per year. With the development of a new system, the waste managed is 60% with the economic potential generated of 1.08 billion per year.

Abstract

Contamination of leachate due to excessive rainwater infiltration into landfill sites presents a significant environmental and public health concern. This study aims to address the adverse impacts of cadmium (Cd) pollution in leachate, specifically its risks to human health and the environment. To address this issue, the research investigates the use of natural adsorbents to mitigate agricultural waste. Straw and cassava peel, abundantly available in Indonesia due to the country's substantial rice and cassava production, were selected as potential adsorbents. The findings of this study are important for guiding pollution control measures and evaluating community activities near pollution sources, particularly focusing on Cd pollution originating from Putri Cempo in Jatirejo Village, Mojosongo, Jebres, Surakarta. The research shows that cassava peel waste is highly effective in adsorbing cadmium metal levels in leachate, with a significant total effectiveness (EF%) rating of 0.3144. Additionally, the study identifies the optimal burning temperature for activated charcoal derived from cassava peel as 600°C, resulting in the highest EF% value of 0.515152.

Abstract

The amount of available water is becoming more scarce due to increased human demand. As a result, people are now obtaining their water from limited aquifers or deep groundwater from artesian water sources. Nonetheless, the varied properties of the soil and rocks within it do not ensure that the groundwater's quality remains safe from microorganisms or germs. Coliform, one of the bacteria or microorganisms that can increase in groundwater due to variations in the rock lithologies found in different regions. Analysis of coliform bacteria distribution was carried out in 30 drilled wells from confined aquifers spread across the city of Semarang. This research identified total coliforms using the Most Probable Numbers (MPN) method. The presence of coliform bacteria in certain wells was compared with the characteristics of rocks, where in this study area there are several rock lithologies such as volcanic breccia, andesite, pyroclastic breccia, lava, and clay. As for the results of this analysis, it was found that 10% of the samples contained total coliforms that exceeded the maximum limit of 50 CFU/100 ml, where the lithology with the highest total coliform content was found in the basalt area with the highest results, namely TNTC (Too Numerous to Count).

Abstract

The analysis of observed fine particulate matter (PM2.5) in Jakarta, Indonesia, was conducted from January 2021 to October 2023 using hourly monitoring data from AirNow, managed by the U.S. Environmental Protection Agency. Data were collected from two air quality monitoring stations in Central and South Jakarta. Meteorological data, including wind speed, temperature, humidity, and rainfall, were obtained from NASA's global forecasting database. The objective was to understand the correlation between PM2.5 formation and meteorological conditions to identify favorable meteorology during high air pollution episodes. During the dry season (May to August), there was a notable increase in PM2.5, linked to higher temperatures, lower humidity, slower wind speeds, and minimal rainfall. The results showed that meteorological conditions significantly affected PM2.5 concentrations, influenced by seasonal changes. In contrast, the rainy season had lower PM2.5 concentrations due to higher rainfall, humidity, and wind speed, and lower temperatures. Further modeling studies are required to assess the combined impacts of emission build-up and meteorology on recurring PM2.5 episodes in Jakarta.

Abstract

This study investigates the impact of thermophilic anaerobic digestion on biogas production and methane emission reduction from Palm Oil Mill Effluent (POME). Conducted under controlled conditions at 55°C and 65°C, the research aims to optimize biogas yield and reduce Chemical Oxygen Demand (COD) levels. The findings indicate that thermophilic digestion at 65°C significantly enhances biogas production, yielding 1.81 L Biogas per liter of POME over an 8-day period, compared to mesophilic conditions. Furthermore, the study demonstrates substantial COD reduction, supporting a more efficient and environmentally friendly process. By capturing methane emissions and converting them into a renewable energy source, this method aligns with global climate policies and greenhouse gas reduction targets. The integration of thermophilic anaerobic digestion into POME treatment presents a viable solution for the palm oil industry to improve waste management practices and contribute to sustainable development goals. Future research should explore large-scale implementations to maximize the environmental and economic benefits of this technology.
