Abstract

Leachate resulting from the decomposition of organic waste is still a challenging problem, especially in landfill management.  Constructed wetlands (CW) are effective, economical, and environmentally friendly options to treat landfill leachate. Biochar added into CW as a pollutant adsorbent in leachate treatment.  This study aimed to determine the effectiveness of sub-surface flow CW amended with biochar in reducing leachate pollutants. Biochar was synthesized from crumb rubber scrap waste using pyrolysis. The variation biochar in CW i.e. CW0 without biochar as a control system, CW1 10% biochar, CW2 20% biochar, and CW3 30% biochar.  Leachate samples flowed into each CW reactor for 10 days of retention time.  The scanning electron showed that the biochar pores ranged from 5-10 կm, containing elements of C, O, Ca, N, Mg, Al, Si, and Fe.  Some elements have greater cumulative mass and atomic percentage values i.e. C 34.51%, O 26.54%, and Ca 21.85%.  The result of CW treatment showed that the CW system was able to remove 76-88% BOD5, 70-87% COD, and 67-81% TSS.  The addition of biochar in CW increased pollutant removal by 7-14%, showing that biochar is able to increase pollutant adsorption in wastewater and improve CW performance. Furthermore, converting organic waste into biochar is highly recommended as a sustainable way to generate useful resources.

Abstract

Illegal gold mining caused various environmental damages in the world. Indonesia is one of the countries with abundant mineral reserves, especially Jambi Province. Jambi has much of natural resources, such as coal and gold. Unfortunately, the management of these natural resources has not been appropriately managed, which has resulted in much illegal gold mining. Illegal mining activities have caused environmental damage, mainly decreased water quality and changed landscapes. This paper explains the illegal mining activities at Jambi Province, including its history, socio-economic and environmental impacts, as well as recent technologies to reduce the environmental damage. Quantitative and qualitative methods were used in this research, including interviews, questionnaires, and laboratory measurements. The results showed that the people of Sarolangun, Bungo, and Tebo were aware that their illegal gold mining activities caused environmental damage. However, economic conditions and insufficient employment opportunities made unlawful gold miners have no other choice. Illegal gold mining activities have also shifted people's livelihoods who previously worked as farmers.

Abstract

Coal waste contains few macro-and micronutrients, which makes it less likely to become a growth site for microorganisms. One way to screen coal waste resources is to identify the diversity of microbes in them to study the relationship between these microbial communities in contributing to improving environmental pollution using metagenomics to determine microbial diversity. The purpose of this research is to study the diversity of microorganisms in areas contaminated with heavy metals using a metagenomic method. This study was performed using next-generation sequencing techniques, including DNA extraction, 16S rRNA amplification, and gene sequencing analysis. The results of this research found that the 10 most commonly found species were Baekduia soli, Nocardiodes iriomotensis, Nocardioides mesophilus, Nocardioides pakistanensis, Propionibacterium cyclohexanicum, Solirubrobacter ginsenosidimutans, Gemmatirosa kalamazoonensis, Roseisolibacter agri, Kosakonia saccahri, and Dickeya fangzhongdai. Based on this research, it can be concluded that most of the microbial communities from coal waste are dominated by the phylum Actinobaceria. The results of this study can be used as an adaptive microbial germplasm for industrial waste management strategies.

Abstract

Gas emissions occurring in the agricultural land of Nglobo Village, Blora Regency, Indonesia, have led to land contamination, resulting in worsened of watershed health over time. The evidence is apparent in the water and soil quality exceeding water quality standard. Consequently, conflicts have arisen in the community due to failed harvests of rice and corn, impacting crops failed. The aim of this research is to restore the health of the contaminated watershed, addressing both agricultural land and water quality. The methodology in this research involves a micro watershed management approach, which includes discussion activities with the community and other parties, remediation efforts, field schools and monitoring and evaluation. The study findings suggest that the addition of organic fertilizers to restore soil fertility, particularly enhancing soil organic carbon, is crucial. This is achieved by applying 29.58 tons/ha to 30.14 tons/ha of fertilizer on the affected land. Post-remediation water quality shows values below the threshold, indicating the health of the Nglobo river basin. The results of the planting test evaluation showed that rice and corn were in good condition, as evidenced by the absence of crop failure, and the fertility of agricultural land could be restored.  Micro watershed management approach, of measurable, with real action together with the affected communities and related parties, can resolve social conflicts that occur due to pollution of community agricultural land.

Abstract

Sugihmanik Village in Grobogan Regency, Central Java, has many people who work as tofu producers. However, this village is experiencing an environmental management crisis, one of which is the management of sludge resulting from the liquid waste processing process at their wastewater treatment plant (IPAL). One of the proposed solutions is the use of tofu waste sludge as maggot feed, which can provide economic benefits and reduce environmental pollution. The Krida Manik Waste Bank is expected to be a pioneer in managing and utilizing tofu mud to feed maggots which can later be used as animal feed. This study uses a qualitative descriptive method where data is extracted as much as possible to obtain information regarding program management. The results of the activity show that there is potential for managing IPAL sludge using maggots. With the abundant potential of mud, people can use it as a renewable resource. However, capacity development and ongoing assistance need to be carried out to get maximum results.

Abstract

Air pollution in Grobogan Regency, especially particulate parameters, annually shows an average value of 69% of ambient air quality standards with an average concentration of PM2.5 reaching 38 μg/m³, primarily due to industrial activities, transportation, and the burning of fossil fuels. In the Sugihmanik Village Tofu Industrial Centre, Grobogan Regency, there are 30 home-based tofu SMEs that use rice husks as fuel for boiler furnaces, which produce pollutants such as SO₂, NO₂, CO₂, CO, PM₂.₅, PM₁₀, and TSP. The largest tofu factory in Sugihmanik Village uses 400 kg of rice husks daily. The chimney design, which does not comply with the technical standards of Kepdal No. 205 of 1996, further increases the risk of air pollution. Therefore, the design of an air pollution control device and a chimney redesign are required to mitigate these negative effects. After calculating the emission concentrations and comparing them with PermenLH No. 7 of 2007, only total particle parameter close to the quality standard of 350 mg/m3 with a particulate loading emitted from the furnace of 232 mg/s. By using a cyclone as an emission control device, there is a particulate removal efficiency of 53.05%. With the implementation of air pollution control devices, the ambient air concentration of particulates, previously a peak concentration of around 300 µg/m3, can be reduced to around 68.8 µg/m3.

Abstract

Industrial activities can cause negative impacts, one of which is the result of the production process which can cause pollution and environmental damage if the company does not process B3 waste in accordance with applicable regulations. With increasing concern for the environment, many companies or other interested parties are required to process liquid waste. Therefore, this study aims to find out from several existing research journals about the effectiveness of wastewater treatment methods and processes Poly Aluminum Chloride (PAC) and Aluminum Sulfate (Alum). The analysis method uses several software to find out the results of research analysis from several existing scientific literature. By using blibiometric analysis, it was found that research on wastewater treatment mostly uses coagulation and flocculation methods which have developed every year. To improve the results of wastewater treatment, it is necessary to consider several influencing factors such as dose, speed and duration of stirring during the experiment. From the results of several previous studies, it was found that the use of Poly Aluminum Chloride (PAC) was the most effective compared to Aluminum Sulfate (Alum) by comparing the decrease in the results of testing the specified quality standard parameters (for example pH,COD, BOD, turbidity, TSS, etc)

Abstract

Sugihmanik Village, a major tofu production center, produces substantial amounts of organic waste, particularly wastewater that contaminates local rivers and disrupts the surrounding ecosystem. A community service program has been developed to convert tofu waste sludge into maggot feed, followed by drying using a hybrid solar and gas-powered maggot drying machine. Initial activities involved program outreach and technical training on maggot cultivation and the drying process. A drying trial demonstrated that 200 grams of wet maggots were reduced to 114 grams within seven minutes. Monthly drying operations required only four 3-kg LPG cylinders, resulting in 81 kilograms of dry maggots and a potential monthly income of IDR 4.050.000. Environmental degradation caused by tofu waste has been significantly mitigated, while local economic productivity has improved. The drying machine enhances the commercial value of maggots as durable livestock feed. The initiative strengthens the operational sustainability of the Krida Manik Waste Bank and offers a scalable model for resource-based environmental solutions.

Abstract

Industri lokal merupakan salah satu pilar utama dalam upaya meningkatkan perekonomian masyarakat. Namun, apabila keberadaannya tidak diiringi dengan upaya pengelolaan lingkungan yang baik, industri tersebut justru dapat menimbulkan permasalahan baru. Pengolahan limbah yang efektif diperlukan guna mendukung keberjalanan industri agar tetap berkelanjutan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan solusi terhadap permasalahan limbah industri ethanol yang mereka hadapi. Salah satu solusi yang ditawarkan adalah memanfaatkan limbah tersebut menjadi Pupuk Organik Cair (POC). Metode pelaksanaan yang dilakukan mencakup kegiatan praktikum, pengujian, serta sosialisasi yang mencakup pelatihan kepada masyarakat. Hasil pengujian dan sosialisasi menunjukan limbah yang dihasilkan oleh industri ethanol dapat dijadikan sebagai pupuk organik cair. Namun produk POC yang dihasilkan belum dapat memenuhi standar baku mutu yang telah ditetapkan dengan kandungan N sebesar 0,08%, P sebesar 0,2%, K sebesar 0,9%, dan C-Organik sebesar 2,7%. Oleh karena itu, dalam penerapannya pada lahan pertanian, pupuk ini hanya dapat berperan sebagai pupuk pelengkap yang berfungsi untuk memperbaiki kualitas tanah. Meskipun demikian, program ini dapat meningkatkan pemahaman masyarakat mengenai mekanisme pengolahan limbah ethanol menjadi pupuk cair yang dibuktikan dengan 53,37% peserta mengalami peningkatan pengetahuan cara pengolahan limbah tersebut. Upaya pengembangan masih diperlukan untuk mengoptimalkan proses pengolahan ini.
