Abstract

This study, carried out between May and June 2023, aimed to assess the influence of landfill leachate on environmental conditions, specifically regarding the pollution of river water near the Banyuroto landfill. The parameter of the difference heavy metals in this study are Mercury (Hg), Cadmium (Cd), Lead (Pb), Chromium (Cr), Manganese (Mn), Copper (Cu), and Iron (Fe). The potential ecological risk index is investigated due to the harm to the nearby river ecology. The sampling was conducted at eight discrete locations in close proximity to the dump. The levels of heavy metals were quantified using Atomic Absorption Spectroscopy (AAS). Furthermore, the Potential Ecological Risk (PER) technique was utilized to assess the potential environmental dangers that these metals may pose. The findings unveiled disparate concentrations of heavy metals across the various locations where point 5 of the sampling become most polluted area due to increased anthropogenic activities. The Mercury (Hg) concentrations ranged from 0.014 to 0.032 mg/kg, whereas the Cadmium (Cd) and Chromium (Cr) levels exhibited minimal variation in the below Limit of Detection (LOD). Lead (Pb) exhibited LOD readings, suggesting their minimum presence. The concentrations of Manganese (Mn) and Copper (Cu) were relatively low, whereas Iron (Fe) exhibited the greatest levels, ranging from 0.2405 to 1.2209 mg/l. The maximum potential ecological risk values were calculated and ranked from highest to lowest as follows: Hg (262.19) > Fe (20.35) > Cr (0.374) > Cd (0.245) > Cu (0.297) > Mn (0.100). Remarkably, the possible environmental hazards associated with all heavy metal characteristics constantly remained below the threshold of 40 except the maximum concentration of the total of Heavy Metals. This indicates that their concentrations present a substantial ecological danger in some situations.

Abstract

Leachate from the Final Disposal Site (TPA) in Piyungan, Yogyakarta, is a significant source of potential heavy metal contamination. This represents a serious environmental issue as it can pose a threat to human health and ecosystems. Given its significant negative impact, this study aims to evaluate the efficiency of Compost-Based Activated Carbon (CBAC) as an environmentally friendly alternative solution for reducing heavy metal concentrations in leachate. CBAC is produced through a pyrolysis and chemical activation process using 32% HCl. The study tested the ability of CBAC to adsorb Cr, Cu, and Pb from leachate samples. The results indicate that CBAC exhibits significant adsorption capacity, with the highest removal efficiency recorded for copper (Cu), reaching 52.38% in 20 minutes. The removal efficiencies for chromium (Cr) and lead (Pb) were 17.8% and 12.09%, respectively, although at different optimal times. These differences in efficiency suggest that the characteristics of each heavy metal influence its interaction with CBAC. The findings demonstrate the potential of CBAC as an effective and sustainable alternative in waste management, particularly in reducing heavy metal pollution. This study makes a significant contribution to the development of more environmentally friendly and sustainable waste management technologies, offering an innovative solution to address heavy metal contamination issues at TPA Piyungan and similar sites.

Abstract

One of the urgent issues worldwide is infectious waste, which impacts both the environment and health. Infectious waste includes various types of medical waste, such as disposable diapers and sanitary pads contaminated with hazardous materials like blood, bodily fluids, and other pathogens. If not properly managed, infectious waste can lead to the spread of diseases. The village of Tanjungrejo, located in the Ngombol subdistrict, has a well-managed TPS3R Waste Bank, but one of the issues they face is the lack of a management method for infectious waste like disposable diapers and sanitary pads. In Tanjungrejo, infectious waste is often disposed of by being dumped into streams or burned along with other waste due to the lack of proper facilities for managing infectious waste. This method of waste management can lead to the transmission of diseases and environmental pollution, such as water, air, and soil contamination. Based on these issues, the aim of this community service project is to develop technologies and innovations to help address environmental problems, including the management of infectious waste. The project will use the Design Thinking method, which includes the stages of empathize, define, ideate, prototype, and test.

Abstract

Waste management is one of the criteria for the evaluation of Green campus and sustainable university. Organic waste takes place in concern because of the domination of waste in university, such as food waste and dry leaves waste. Mismanagement in dry leaves will promote the campus area to look dirty. One method to control the dry leaves waste is the vermicomposting process. The purpose of this research is to evaluate the macronutrient content of dry leaves compost after the vermicomposting process. The research was conducted in the Faculty of Civil engineering and Planning, Universitas Islam Indonesia, Yogyakarta. The vermicompost sample in this study refers to the quality standards according to SNI 19-7030-2004 regarding compost quality standards. The results of vermicompost content value are obtained on day 56 is Phosphor amounting to 0.194%, amounting to 0.129% Potassium, and C / N ratio of 7.73. From the data that has been obtained can be concluded that the results of vermicompost are less effective as organic compost compared to the standards.

Abstract

Microplastics, recognized as emerging contaminants, have been detected in numerous rivers globally. This study focuses on the Ciliwung River in Jakarta, examining the influence of seasonal variations—specifically the rainy and dry seasons—on microplastics' concentration, types, and colors. Sampling was conducted during November 2022 (dry season) and March 2023 (wet season) using a plankton net for water (10 liters) and an Ekman grab sampler for sediment (400 mililiters). Microplastic abundance was analyzed following the National Oceanic and Atmospheric Administration (NOAA) adaptation method, and their material characteristics were identified using Fourier Transform Infrared Spectroscopy (FTIR) testing. Results revealed a notable seasonal impact: in the dry season, average microplastic abundance was 530 particles/liter in water and 859 particles/100 grams in sediment, whereas, in the wet season, these figures rose to 1,111 particles/ liter and 1,583 particles/100 grams, respectively. Fragments were the predominant type of microplastics, and black was the dominant color in both seasons. This consistency suggests similar sources and activities contributing year-round to microplastic pollution in the Ciliwung River.

Abstract

Indonesia has experienced a significant period of community-based waste management that has gained global recognition. Initiatives such as waste banks, 3R waste processing facilities (TPS 3R), waste donation programs, and creative communities such as Pandawara Group reflect the strength of public participation in addressing waste-related challenges. However, these approaches have begun to reveal their limitations, as they are often sporadic, unsystematic, and insufficient to address structural issues, including inadequate waste management services, institutional dualism between regulators and operators, and limited local government financing. Indonesia is currently facing emerging challenges, such as overcapacity at final disposal sites (TPAs), landfill fires, leachate pollution, and increasing waste generation driven by rapid urbanization. This article aims to analyze the transition of waste management in Indonesia from a community-based approach toward a modern system that incorporates Waste-to-Energy (WtE) technology. The study was conducted through a literature review and policy analysis of waste management practices implemented across various regions. The findings indicate that the success of this transition depends not only on technological and infrastructural readiness but also on the integration of formal waste management systems with community participation at the grassroots level. Future waste management models in Indonesia should position communities as strategic partners within the WtE framework in order to achieve waste management that is equitable, efficient, and sustainable.
