Abstract

Various methods of clean water treatment have been developed to meet the needs of communities, one of which is coagulation-flocculation, an effective process for removing TSS and turbidity. This process involves mixing coagulants to form flocs, followed by aggregation of suspended particles to facilitate sedimentation. Reactor modifications, such as hydrocyclone flocculators, are designed to improve efficiency, although their effectiveness depends on the size and density of the flocs. Chemical coagulants such as alum and PAC are widely used because of their effectiveness, but their residues can be potentially toxic. As an alternative, biocoagulants such as papaya seeds have been developed to provide a safer solution and produce biodegradable residues. A study was carried out to compare the efficacy of alum, PAC and biocoagulants using a hydrocyclone flocculator with test waters representing low, medium and high TSS levels. Samples were taken at 0, 5, 10, 15 and 20 minutes. The results showed that PAC had the highest efficiency with an average of 78.9% for high TSS, 75% for moderate TSS and 70.8% for low TSS.

Abstract

Rapid population growth in Indonesia has led to a significant increase in the volume of waste, which poses a potential threat to the environment. Leachate is a liquid produced when external water infiltrates waste heaps, dissolving both soluble and organic materials through biological decomposition processes. Without proper management, leachate can contaminate water sources and endanger the ecosystem and nearby communities, particularly around the Jabon Landfill (TPA Jabon). One effective method of treating leachate is the use of constructed wetlands, a simple system that uses aquatic plants and microorganisms to reduce pollution. This study evaluates the effectiveness of two aquatic plants, papyrus (Cyperus papyrus) and bulrush (Typha latifolia), in reducing the chemical oxygen demand (COD) of leachate through the constructed wetland system.

Abstract

Surface water in Bojonegoro Regency plays a crucial role in meeting domestic, agricultural and ecosystem needs. However, various human activities, such as excessive use of chemical fertilizers in agricultural areas, have led to a decline in water quality. This study analyses the surface water quality using the National Sanitation Foundation Water Quality Index (NSF-WQI) method based on eight parameters: temperature, TDS, pH, DO, BOD, nitrate, phosphate and fecal coliform. The results of the analysis indicate that the surface water quality status falls into the "medium" category, with index values ranging from 51 to 70. Most parameters meet the Class II quality standards set by Government Regulation No. 22 of 2021, but elevated phosphate levels indicate the potential for eutrophication caused by agricultural activities. To maintain water quality, regular monitoring, public awareness campaigns and effective management are essential to support the sustainability of water resources in this region.

Abstract

Ambient air quality is a crucial factor affecting human health and the environment. This study aims to analyse the air quality in Bojonegoro Regency through monitoring using the passive sampler method. Monitoring was conducted in four areas: industrial, office, residential and traffic zones. The measured parameters included the concentrations of nitrogen dioxide (NO₂) and sulphur dioxide (SO₂), which were then calculated to determine the Air Quality Index (AQI). The analysis results showed that the average NO₂ concentration in the first phase was 6 µg/m³, rising to 9.25 µg/m³ in the second phase. Meanwhile, the average SO₂ concentration was 11.25 µg/m³ in the first phase and 11.5 µg/m³ in the second phase. The Air Quality Index showed a decrease from 85.784 to 83.160, but remained in the "Good" category. The decrease in the AQI was influenced by increased human activities and environmental conditions such as vehicle and industrial emissions. To improve the AQI to the "Very Good" category, recommended measures include public education, energy efficiency, application of clean technologies, forest protection, shift to public transport and improvement of monitoring systems.

Abstract

Tenggilis Mejoyo Sub-district, Surabaya, has significant potential for Green Open Spaces (GOS) to support carbon emission reduction in urban areas. This study aims to analyse the carbon stock potential of GOS in the area and evaluate their role in carbon emission mitigation. Primary data were collected through field surveys measuring tree diameter and height using the allometric method, while secondary data were obtained from relevant literature. The results show that the total area of green lanes in Tenggilis Mejoyo is 33,227.5 m², with a carbon storage capacity of 275.35 tonnes. This capacity can only absorb 0.33% of the total carbon dioxide (CO₂) emissions from the transport sector in 2019, which amounted to 83,336.73 tonnes, leaving 83,061.38 tonnes/year unabsorbed. An additional 145.97 hectares of GOS are required to offset the remaining carbon emissions. This study also shows that active parks were not included in the carbon stock analysis, which are likely to increase the overall contribution to carbon sequestration. Therefore, further research on carbon stocks in active parks within Tenggilis Mejoyo is highly recommended. The results of this study are expected to serve as a basis for environmental policy planning and more effective GOS management in Surabaya.

Abstract

Air merupakan unsur yang sangat penting bagi kelangsungan hidup di bumi. Akan tetapi kualitas air di permukaan bumi ini tiap tahun kian mengalami penurunan tak terkecuali air sungai. Salah satu sungai besar yang ada di Kota Surabaya adalah Kali Surabaya, dimana sungai ini mensuplai sebagian besar air baku yang diolah PDAM Kota Surabaya menjadi air bersih untuk masyarakat Kota Surabaya. Akan tetapi air dari sungai ini mempunyai kualitas yang kurang baik. Salah satunya karena tingginya kekeruhan pada sungai ini. Kekeruhan yang tinggi ini menyebabkan pemanfaatan air sungai secara langsung sangat terbatas serta memerlukan pengolahan yang cukup sulit untuk mengubahnya menjadi air bersih. Kekeruhan ini dapat disebabkan oleh senyawa organik yang berasal dari tergerusnya tanah sepanjang aliran sungai, pelapukan bahan organik, dsb; maupun oleh senyawa anorganik yang berasal dari limbah industri di sepanjang aliran sungai. Oleh karena itu diperlukan penelitian untuk mengetahui penyebab dari kekeruhan tersebut. Penelitian ini dilakukan dengan menguji air sampel selama bulan April 2023. Data yang diperoleh kemudian diolah menggunakan software Minitab. Hasil running pada software Minitab terhadap data kekeruhan dan senyawa organik (KMnO4) ini didapatkan korelasi yang tinggi dengan nilai p-value = 0,803. Hasil ini menunjukkan bahwa senyawa organik mempengaruhi besarnya kekeruhan pada Kali Surabaya.

Abstract

The tobacco industry is a strategic sector that significantly contributes to the national economy; however, its operations also generate hazardous and toxic waste (B3) that poses a risk to the environment. The objective of this study is to evaluate the B3 waste management system that has been implemented by PT. XYZ, with a particular emphasis on the reduction and management of waste, with a focus on storage practices. A descriptive methodology was employed, combining direct observation and document analysis of existing conditions, which were then compared against the provisions of the Minister of Environment and Forestry Regulation No. 6 of 2021. The evaluation employed a Likert scale to assess the level of compliance with the regulations. The findings indicated that PT. XYZ has been identified as a producer of nine distinct categories of B3 waste, with the primary sources of these materials being attributed to various production activities and maintenance procedures involving machinery. The waste reduction aspect achieved a compliance score of 62.5%, which is categorized as "Good," while the storage aspect reached 95.45%, which is categorized as "Very Good." The overall score was determined to be 78.97%. These results suggest that, despite the effective implementation of waste storage practices, enhancements are necessary in the domains of reporting and the utilization of waste reduction technologies, with the objective of aligning with the principles of sustainable development.

Abstract

IPAM Karangpilang II merupakan salah satu instalasi pengolahan air minum yang di miliki PDAM Surya Sembada Kota Surabya. IPAM ini menggunakan unit filtrasi untuk mengolah air baku menjadi air minum yang layak konsumsi. Filtasi merupakan proses pengolahan air dengan cara mengalirkan air melalui media filter dengan diameter tertentu yang bertujuan untuk memisahkan koloid dari cairannya. Pada proses filtrasi ini beberapa parameter pencemar seperti kekeruhan, warna, dan kandungan bakteri dapat dihilangkan. Akan tetapi seiring penggunaannya media filter yang digunakan pada proses filtrasi akan mengalami penurunan efektivitas. Hal ini dapat terjadi karena tersumbatnya pori-pori media filter oleh koloid dan pengikisan ukuran media filter akibat proses pembersihan (backwash) untuk membersihkan koloid yang menempel di pori-pori media filter. Untuk mengetahui ke efektivan dari media filter perlu dilakukan pengujian salah satunya menguji output dari unit filtrasi berdasarkan parameter yang mampu tersaring seperti parameter mikrobiologi. Pengujian dilakukan dengan menggunakan metode MPN dimana sampel ditanam pada media khusus untuk mengukur jumlah bakteri coliform yang ada pada air sampel. Hasil pengujian menunjukkan jumlah penurunan total coliform pada unit filtasi IPAM Karangpilang II sebesar 92,45%, fecal coliform 87,90% dan E. colli 90,00% yang artinya unit filtrasi Karangpilang II dalam kondisi yang optimal dan tidak memerlukan perbaikan.

Abstract

The declining quality of river water due to domestic and industrial activities demands effective water treatment technologies. This study aims to evaluate the effect of varying the number of baffles in a hydraulic coagulation reactor on the removal efficiency of Total Suspended Solids (TSS) and turbidity using two types of coagulants: Ferric Chloride (FeCl₃) and Ferrous Sulfate (FeSO₄). The experiment was conducted with baffle variations of 26, 30, 34, 38, and 42, and sedimentation times of 30, 60, and 90 minutes. The results showed that increasing the number of baffles and sedimentation time improved TSS and turbidity removal efficiency up to an optimum point. FeSO₄ achieved the highest TSS removal efficiency of 97% at 42 baffles and 90 minutes of sedimentation, while FeCl₃ demonstrated more stable and high turbidity removal efficiency, reaching up to 97%. Statistical analysis using ANOVA indicated that the type of coagulant, number of baffles, and sedimentation time significantly affected TSS removal, whereas turbidity removal was more influenced by the number of baffles and sedimentation time. These findings highlight the importance of proper hydraulic design in optimizing the coagulation-flocculation process for more efficient water treatment.
