Abstract

Introduction: Landfill wastewater or leachate has unique characteristics. Several conventional methods need a few treatment tanks to cover the treatment process. A Sequencing Batch Reactor (SBR) is a biological treatment method that uses a single tank with few-cycle phases. This study aims to determine the potential of a Sequencing Batch Reactor (SBR) that can be used to treat landfill leachate. Methods: A Sequencing Batch Reactor (SBR) was used in this study. The characteristics of leachate served as the basis for the design of the SBR reactor. The synthetic leachate was used to create the reactor feed based on the actual landfill leachate compositions. The reactor's influent and effluent were analyzed based on a few parameter changes, such as Suspended Solid (SS), Chemical Oxygen Demand (COD), ammonia nitrogen (NH3-N), and Total Kjeldahl Nitrogen (TKN). Results and Discussion: While the experiment was running, 84% of SS were removed, 88% of COD were removed, a -28% efficiency rate for NH3-N removal, and a -172% efficiency rate for TKN removal. After the withdrawal phase, the supernatant showed promising results with 99% COD removal, 97% SS removal, and 65% TKN removal. Unfortunately, the removal of NH3-N reaches -130%. It indicates insufficient concentrations of MLSS and SRT, as well as the presence of a eutrophication process. Conclusion: SBR shows a promising result for leachate treatment. Few changes in the cycling process were needed for further study, so the treatment process becomes optimal to reach its full potential.

Abstract

The pulp and paper industry produces the remaining bark as solid waste, where this solid waste pile when it rains will produce leachate that seeps into the ground, causing soil and groundwater pollution. This wood waste can be used as activated carbon (adsorbent) for leachate treatment. The research was divided into two stages, namely adsorbent production and leachate treatment. Production of activated carbon from bark (bark) was activated using a solution of NaOH and H2SO4 as an activator, with variations of bark (gr): activator (ml) = 20:100; 50:200; 70:300. The leachate adsorption process used activated carbon with a mass of 2.5 and 5 g for 30, 60 and 120 minutes. The lowest adsorbent water content was 0.87% activated using NaOH, and the lowest ash content 0.79% when activated with H2SO4. This is still in accordance with the SII standard No.0258-88. The best variation occurred when the addition of activated carbon which was activated using 5 grams of H2SO4 for 120 minutes caused the most significant decrease in COD value of 52%, and pH 7.32. From the variations in the activation of activated carbon adsorbents, the activation of acidic solutions is better in leachate treatment.

Abstract

Tofu production is known to generate large amounts of wastewater containing a variety of organic compounds, chemicals, and potentially hazardous substances. It is very important to apply proper treatment of harmful substances that impact this wastewater. The aim of this study is to explore advanced techniques for treating tofu wastewater by combining multilevel filtration and TiO2 photocatalysis methods. To evaluate the efficiency of the treatment process, influent and effluent parameters, including pH, total suspended solids (TSS), and chemical oxygen demand (COD), are carefully monitored and measured. The results clearly demonstrate the impressive removal efficiency achieved through the combined use of multilevel filtration and TiO2 photocatalysis in treating tofu wastewater. The treated wastewater showed a promising efficiency in pH (100%), a significant decrease in TSS (40%), and COD (72%). the final measurements of pH met the standards set by government regulations, indicating successful remediation of these specific parameters. Even though TSS and COD haven't met the standard limits, each of them shows a very promising efficiency improvement. Towards the end of this study, it is suggested that the combination of these methods holds promise for effectively remediating tofu wastewater.

Abstract

The content of Al and Fe in coal fly ash has underpinned several studies on the use of coal fly ash as a coagulant and adsorbent. Coal fly ash coagulant was activated with H2SO4. While coal fly ash adsorbent is activated with HCl. This study aims to compare the effectiveness of the  coagulant  or  as   adsorbent,  to determine the optimum concentration of coagulant/ adsorbent addition, and to determine the effectiveness of fly ash as a coagulant/ adsorbent in reducing COD and TSS in Pulp and Paper wastewater. This research used 2 treatments, activating coal fly ash with 2M H2SO4 and 4M HCl, and then comparing the effect of fly ash coagulants and adsorbents in reducing COD and TSS wastewater. The results showed that coagulant reduced COD by 53.23% and TSS by 60.1%, more effective  than  adsorbent  which  only reduced COD by 6.38%, and increased TSS value by 7.2%. However, it has not yet below the quality standards. Numerical  analysis  using  3rd  order polynomials shows that doses of 41,000-42,000 ppm of coagulant can reduce COD below the quality standard. This concludes is coal fly ash coagulant is effective in reducing COD and TSS of pulp and paper wastewater, with the optimal dose to reduce COD below the quality standard, is 41,000 - 42,000 ppm.

Abstract

Pengelolaan sampah di Kelurahan Pasir Putih, Jambi Selatan, menjadi tantangan serius yang memerlukan solusi inovatif. Artikel ini membahas strategi keberlanjutan lingkungan melalui kolaborasi antara akademisi, masyarakat, dan LSM. Peningkatan jumlah sampah yang tidak terkelola dengan baik menandai urgensi tindakan. Inisiatif ini melibatkan Program Studi Teknik Lingkungan Universitas Jambi, dengan fokus pada RT 16. Metode kegiatan melibatkan fase observasi lapangan, perencanaan, kolaborasi, dan eksekusi. Sosialisasi dan pembersihan area sungai menjadi bagian integral dari kegiatan tersebut. Evaluasi menunjukkan peningkatan pemahaman masyarakat tentang nilai ekonomis sampah. Bank Sampah Bangkitku dan Bank Sampah Sihkumbang berperan dalam pengangkutan dan monitoring lanjutan. Hasilnya menciptakan kerjasama dengan pola Bank Sampah mini di RT 16 Pasir Putih, yang dapat mengurangi volume sampah menuju Tempat Pemrosesan Akhir (TPA) Talang Gulo. Pendekatan ini diharapkan dapat menjadi model inspiratif bagi komunitas lain dalam mengatasi tantangan pengelolaan sampah di tingkat lokal.

Abstract

Mining, particularly gold mining, is a lucrative industry. However, it poses significant environmental risks, such as releasing heavy metal elements into the soil and water. After gold mines are exhausted, whether they are small or large scale, the excavated sites often need to be repaired. This situation has led to a global concern regarding the presence of heavy metals from mining activities, which are known to be carcinogenic and harmful to living organisms. The concentration of heavy metals in these areas often surpasses safety limits, necessitating advanced treatment methods for their removal, especially lead (Pb) compounds from gold mining waste. One effective treatment method is the adsorption process. This study examined POFA's inherent capacity to remove lead from water contaminated by gold mining without modification. This method was preferred due to its high efficiency and cost-effective option for removing heavy metal compounds. According to the experiment's results, the largest adsorption capacity of 0.816 mg/g was followed by the greatest removal efficiency of 91.837%. The isotherm analysis found that the Langmuir model provided an outstanding fit for the experimental data. Thus, this relationship suggested that on the surface of the POFA, a monolayer and an adsorption process suitable for physical adsorption took place.

Abstract

The need for clean water in Muara Sebapo Village remains a serious issue to this day. The water obtained by the community from dug wells or boreholes often appears yellow and has an unpleasant odor. This water typically has a high concentration of Fe3+ ions, causing the water to turn yellow and become odorous. On the other hand, Muara Sebapo Village has extensive oil palm plantations, which generate solid waste in the form of Empty Palm Fruit Bunches (EFB). Until now, this waste has been underutilized, and in some cases, it has been disposed of or burned. Therefore, efforts are needed to address this issue so that the community can access clean water and utilize waste wisely. In this program, outreach and education are conducted on how to treat well water using solid waste EFB effectively. EFB waste can be transformed into activated carbon, which can be used as a water purification medium in a water treatment unit in the plantation areas and the surrounding community. Activated carbon will act as an adsorbent capable of adsorbing metal ions and organic pollutants present in well water.
