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

Abstract

Waste is a crucial issue with far-reaching impacts on the environment, public health, and economy. The Putri Cempo landfill receives waste from Surakarta City. Waste can pollute the river near the landfill, given the location of the river that adjoins and is close to residential areas. The purpose of this research was to analyze the river water quality around the Putri Cempo landfill for heavy metals Pb and Mn. The research was conducted by taking samples directly from the river and then analyzing the heavy metal content. The results were compared with river water quality standards according to Indonesian Government Regulation 22/2021. The results showed that the Pb content in river was -0.02392344 mg/L and Mn was 4.206021703 mg/L. From these results, the Pb content in the river did not exceed the quality standard limit, whereas the Mn content exceeded the quality standard limit. It can be concluded that the river water around Putri Cempo landfill has been contaminated with Mn. Heavy metals in high levels can harm living things and the environment, can cause death to aquatic biota and plants, disease in humans, degrade water quality and damage river aesthetics. Further evaluation of stakeholders is required to address heavy metal pollution

Abstract

Seiring dengan bertambahnya jumlah penduduk dan pertumbuhan ekonomi, maka terjadi peningkatan timbunan sampah di hampir semua kota di Indonesia. Sementara kondisi tempat pembuangan akhir (TPA) sampah saat ini sudah atau hampir penuh, sehingga tidak bisa menampung sampah lebih banyak lagi. Oleh karena itu, perlu ada solusi jangka pendek untuk menjawab permasalahan kedaruratan sampah ini. Kajian ini menganalisis beberapa teknologi alternatif yang dapat digunakan untuk mengolah sampah padat perkotaan menjadi sumber energi. Dari hasil review, teknologi termal merupakan proses yang paling cepat dan meninggalkan residu yang paling sedikit. Teknologi termal yang dapat diterapkan yaitu pembakaran/insinerasi, gasifikasi, dan pirolisis. Teknologi insinerasi dapat digunakan pada skala besar karena melibatkan proses yang menggunakan ketel uap (boiler) dan turbin. Sementara gasifikasi lebih cocok diterapkan pada skala yang lebih kecil dengan menggunakan mesin gas atau mesin diesel sebagai pembangkit listriknya. Sedangkan pirolisis lebih sesuai untuk jenis sampah homogen dan tertentu seperti plastik dan ban bekas.
