Abstract

The wastewater generated from the tofu industry often contains elevated levels of COD and TSS pollutants. One effective method for treating this wastewater is through the coagulation-flocculation process. Moringa seeds, recognized as a biomass with natural coagulant properties, contain a bioactive compound known as 4αL-rhamnosyloxy-benzyl-isothiocyanate, capable of adsorbing particles present in wastewater. The objective of this study is to assess the efficiency of reducing pollutant parameters (COD, TSS, and Turbidity) in wastewater from the tofu industry by utilizing Moringa seeds as a natural coagulant. The research was conducted using a jar test apparatus with coagulation stirring at 100 rpm and flocculation at 40 rpm for 12 minutes. The study involved varying coagulant doses (2, 3, 4, 5, and 6 g/L of tofu wastewater) and coagulation stirring times (1, 3, and 5 minutes). Based on the results obtained, the optimal stirring duration and dose, as well as the efficiency of reducing each pollutant parameter, were determined. For COD, the optimal conditions were found to be 3 minutes stirring time with a dose of 4 g/L, resulting in an efficiency of 64.88%. Similarly, for TSS parameters, the optimum conditions were achieved with 3 minutes of stirring time and a dose of 4 g/L, yielding an efficiency of 52.71%. Lastly, for turbidity, the most effective conditions were observed with 3 minutes of stirring time and a dose of 4 g/L, with an efficiency of 58.85%.

Abstract

Acid mine drainage is one of the major pollutants generated from coal mining activities, characterized by high concentrations of heavy metals such as Fe and Mn and very low pH levels, making it unsuitable for environmental discharge. This study aims to analyze the effect of different chemical activators (NaOH, H₃PO₄, HCl, and no activator) on the effectiveness of activated carbon made from sengon wood in removing contaminants from acid mine drainage. The carbonization process was carried out at high temperatures, followed by chemical activation and application as filtration media. The results showed that unactivated carbon provided the highest TSS removal efficiency at 65.79% and increased the pH to 2.7. However, all variations of activated carbon were ineffective in removing Fe and Mn, likely due to the low initial pH causing protonation of functional groups on the carbon surface, thus reducing their adsorption capacity. This study indicates that while chemical activation influences the characteristics of activated carbon, it is not yet sufficient for optimal removal of heavy metal pollutants.

Abstract

Terdapat empat sektor utama yang diketahui berkontribusi dalam peningkatan emisi gas rumah kaca salah satunya yaitu sektor limbah padat. Aktivitas antropogenik memiliki potensi untuk melepaskan emisi GRK dan hal tersebut terdapat di Kecamatan Balikpapan Barat. Keberagaman aktivitas masyarakat Kecamatan Balikpapan Barat juga memicu peningkatan timbulan sampah. Penelitian ini bertujuan guna mengidentifikasi timbulan, komposisi, karakteristik sampah organik, menginventarisasi emisi GRK, serta merekomendasikan arahan pengolahan sampah organik berdasarkan aspek teknis. Mengacu pada SNI 19-3964-1994, hasil pengukuran lapangan menyatakan bahwa besaran timbulan sampah pemukiman sebesar 0,145 Kg/orang/Hari dan 0,1 Kg/m2/Hari besaran timbulan yang dimiliki Pasar Pandansari. Sampah organik mendominasi hasil pengukuran komposisi sebanyak 80% dan berpotensi untuk dikomposkan. Karakteristik sampah Kecamatan Balikpapan Barat memiliki kadar air (90,1%), C-organik (43,89%), N-organik (2,19%), dan nilai rasio C/N adalah 20. Menurut data sampling yang didapat, dari sektor limbah padat Kecamatan Balikpapan Barat tahun 2022 berkontribusi melepaskan sejumlah emisi GRK hanya pada penimbunana sampah sebesar 2.073,57 CO2-eq Ton/Tahun. Perhitungan estimasi GRK dianalisis dengan dua skenario dimana skenario 1 diasumsikan 100% sampah yang dihasilkan diangkut ke TPA tanpa adanya upaya reduksi dan skenario 2 diasumsikan 70% diangkut ke TPA dan 30% dilakukan reduksi dari sumber. Skenario 2 merupakan alur terbaik untuk diadakan pengolahan sampah dimana selisih emisi GRK sebesar 622,07 CO2-eq Ton/Tahun saat hanya ditimbun di TPA dengan total emisi pada penimbunan sampah sebesar 1.451 CO2-eq Ton/Tahun dan pada pengomposan sebesar 179,52 CO2-eq Ton/Tahun. Sampah organik di Kecamatan Balikpapan Barat dapat dimanfaatkan sesuai dengan hasil analisis dan inventarisasi emisi GRK diantaranya sebagai kompos, biodigester, pengkonversian sampah menjadi energi listrik, dan penerapan 3R (reduce – reuse – recycle).

Abstract

Cigarette industry wastewater contains high phenol levels (100 mg/L), exceeding the regulatory limit of 0.5 mg/L (Minister of Environment Regulation No. 5/2014). Phenol is toxic, carcinogenic, and resistant to natural degradation, posing severe environmental and health risks. Existing treatments like ozonation (15.45% efficiency) and adsorption (60–80%) face limitations such as low efficiency and high operational costs. This research aimed to evaluate the bioremediation of synthetic tobacco wastewater using Pseudomonas putida, focusing on the effects of bacterial concentration (3–7%) and nutrient levels (0–2%) on phenol removal efficiency. A batch-culture experiment was conducted under controlled conditions (30°C, 150 rpm, 120 hours). Phenol concentration was measured via UV-Vis spectrophotometry, and bacterial growth was monitored using OD600. Data were analyzed using one-way ANOVA. The highest phenol removal (68%) occurred at 5% bacterial concentration and 2% nutrients, with OD600 = 1.000, indicating optimal bacterial growth. Nutrient variations did not significantly affect efficiency, but temperature fluctuations and carbon catabolite repression were identified as potential limiting factors. Pseudomonas putida offers a sustainable solution for phenol-laden wastewater, achieving near-compliance with regulatory standards. Future studies should optimize environmental controls and scale up the process for industrial applications.

Abstract

Transfer Station is one of the most important parts of waste management operational aspects. The condition of Transfer Station container is often neglected whether it meets the standards based on SNI 19-2454-2002 and Minister of Public Works Regulation Number 3 of 2013 concerning waste containers. The container of Transfer Station can be seen from the characteristics of it such as the shape, nature and material. Waste problems in Karang Rejo Village are caused by several factors such as the decrease in quality, the distribution of Transfer Station points, and community’s behaviour in disposing the solid waste. This study aims to analyze the distribution and provision of Transfer Station, analyze community behavior in disposing of waste and evaluate Transfer Station in Karang Rejo Village based on community behavior in waste disposal. This research is a qualitative research, the research procedures carried out are observation, identification of the provision and distribution of Transfer Station, analysis of Transfer Station conditions in a descriptive qualitative way, distribution and collection of questionnaires, data processing and the evaluation stage of waste containers according to people's behavior in disposing of waste. The results showed that in Karang Rejo Village there were 16 Transfer Station units where the distribution of it, was disproportionate, in terms of supply there were 8 out of 16 Transfer Station units whose buildings were in damaged condition (percentage <60%), 99% of the behavior of the Karang Rejo Village community in disposing of garbage by how to get off the vehicle and throw garbage into the Transfer Station and 90% of the Karang Rejo Village community did not know information about waste containers. The evaluation results showed that the Transfer Station in Karang Rejo Village was not in accordance with the standards and there were 10 units that required total renovation, and 6 units requires the addition of components such as lids on containers.

Abstract

Hospital domestic wastewater comes from the operating room, laundry, bathroom, kitchen and laboratory equipment washing room. The ammonia level in one of the hospitals in Balikpapan is 27.1 mg/L which exceeds the quality standard of 10 mg/L. The high concentration of ammonia can cause eutrophication in water bodies. Therefore, appropriate treatment of hospital wastewater is needed to prevent damage to aquatic ecosystems. The adsorption method is an alternative treatment method in hospital domestic wastewater to set aside ammonia parameters, because the tools applied are simple so that implementation is easy to apply, and the adsorbent materials used are easily available, and also the costs used are cheap and do not require large areas of land. The bioadsorbent used is lai peel and activated with sodium carbonate (Na2CO3). Variations in the dose of lai peel bioadsorbent and contact time had a significant effect on ammonia removal efficiency. The optimum condition occurred at a dose of 1 gram/100mL and a contact time of 50 minutes with an optimum removal efficiency of 73%. Adsorption capacity to the dose of lai peel bioadsorbent has no significant effect while adsorption capacity to contact time has a significant effect. The optimum condition of adsorption capacity occurred at a dose of 0.4 grams/100mL and a contact time of 50 minutes with an adsorption capacity of 2.69 mg/g.
