Abstract

The pandemic caused by Covid-19 has had various impacts on people's lives. One of these impacts is the use of masks when carrying out outdoor activities. Most people use disposable masks, so the amount of disposable mask waste has increased during the pandemic and post-pandemic. This research aims to find out whether people process disposable mask waste during the pandemic until post-pandemic. The research method was carried out using a non-probability sampling method using Google Form. Data analysis was carried out using Likert calculations and elasticity calculations. The results of the research show a decrease in people's behavior towards processing disposable mask waste during the pandemic to post-pandemic with E = 0.535, which means that people's behavior is inelastic.

Abstract

Surakarta is facing serious problems related to waste management at the Putri Cempo landfill. PT. Solo Citra Metro Plasma Power with the Surakarta city government built a waste power plant installation with gasification technology. Tar waste is a gasification liquid product that is dangerous if not managed. This study aimed to determine the heavy metal content and toxicity level of gasified tar waste using the atomic absorption spectrometry (AAS) and lethal dose-50 (LD50) acute toxicity test. The parameters of heavy metals tested are lead (Pb), copper (Cu), iron (Fe), zinc (Zn), and total chromium (Cr). In the LD50 test, the animals were divided into 5 groups, namely 1 control group and 4 groups with doses of 0.50 mL, 1 mL, 2 mL, and 4 mL. The results showed that the tar contained 17.4 mg/L of iron, 3.5 mg/L of zinc, and <0.01 mg/L of lead, copper, and chromium. Acute toxicity tests did not cause death in the animals but still showed toxic symptoms, so the LD50 value is declared pseudo. The content of some heavy metals in tar is within safe limits and the level of toxicity is relatively harmless.

Abstract

Through this activity, disaster volunteers in Surakarta City can conduct disaster risk reduction (DRR) efforts based on ecosystem data and information management. Climate change has an increasing impact on ecosystems, resulting in environmental damage, thereby increasing the intensity of disaster events that need to be studied and monitored. Managing this disaster risk data and information requires using an environmental information system for ecosystem-based disaster risk reduction (ECO-DRR). The capacity of volunteers is vital in dealing with the risks of natural disasters and the impact of climate change by using SIL. Currently, volunteers manage using a form that has yet to accompany the presentation of information for decision-making and management of disaster risk knowledge. Requires remedial action by increasing the ability of volunteers to manage disaster risk data and information, report disaster events, and present them in dashboards. The method used is the parameters for development of SIL as a solution for ecosystem-based disaster risk reduction (ECO-PRB). The parameters were conducted on the topics of disaster risk, disaster incident reporting, and dashboard information management. The development of ECO-DRR SIL uses Quality Function Deployment (QFD) to obtain information on improvements in developing a user-based digital platform.

Abstract

Linear alkylbenzene sulfonate (LAS) belongs to a class of surfactants claimed as an environmentally friendly detergent due to its biodegradability. However, the disposal of LAS waste into the waters without prior treatment causes a risk to the ecosystem. These experiments aimed to study the effects of commercial inoculum size EM-4 on the aerobic decomposition process of LAS in a well-shaped bioreactor. These experiments of LAS decomposition were carried out in a batch system aerated by 2.5 L/min for the low and high initial LAS concentrations. The effects of inoculum acclimation were also investigated for the high LAS concentration. The effects of inoculum size were explored at sizes ranging from 5 to 20% v/v, and samples were taken on a regular basis for residual LAS assessment. The first-order kinetic model gave the best fit to the rate of LAS decomposition, with the highest rate coefficient of 10.44 x 10-2 hour-1. This was achieved by using a 20% v/v inoculum for the initial low concentration of LAS, resulting in the highest decomposition efficiency of 89.4% after 24 hours of incubation. The decomposition rate was slower at the high LAS concentrations than at the low concentrations. The inoculum acclimation increased the decomposition rate for the high LAS concentrations. The results of this study show great potential for the bioremediation of LAS detergent waste using commercial inoculum in a well-shaped batch bioreactor.

Abstract

This study aimed to develop a model for accelerating the transition to  green economy through the implementation of a climate village focused on food security. It introduced a children-friendly digital education program designed to enhance out-of-class learning on climate change mitigation and adaptation. This study also emphasized the integration of Proklim activities within designated areas to minimize the adverse effects of climate change. A survey method was conducted in Sukoharjo Regency with a sample of 160 respondents of Proklim activists. Primary data were collected using questionnaires, FGDs, and quantitative interviews, while secondary data were collected through documentation. The data were analyzed using geographic information systems, structural equation model PLS, vs code software, MySQL, construct, animate, and travel cost methods. The results showed that accelerating the transition to green economy through a food security-based climate village program involved a combination of adaptation, mitigation, and sustainability efforts. The adaptation measures focused on controlling drought, floods, and landslides, enhancing food security, and managing climate-related diseases. Meanwhile, mitigation efforts included effective waste management for both solid and liquid waste, adoption of renewable energy, conservation practices, energy efficiency, reduction of greenhouse gas emissions, agricultural innovation, and the preservation of vegetation cover. Sustainability was reinforced through the establishment of community groups, promotion of self-reliance, independent funding initiatives, gender-inclusive participation, capacity-building programs, external support, and the development of activities that generate social, economic, and environmental benefits. Digitalization in education is implemented through the Proklim digital platform, KampungIklim.com, which offers out-of-class learning resources on climate change mitigation and adaptation. Proklim activities serve as pilot sites for educational tourism, promoting sustainability by integrating economic value into existing initiatives, including the development of Proklim-based tourism villages.Received: 2024-08-15 Revised: 2024-11-15 Accepted: 2025-02-19 Published: 2025-04-29
