Abstract

Saat ini kualitas badan air semakin menurun akibat pembuangan limbah domestik dan industri secara langsung pada aliran sungai. Kualitas air sungai dengan beban nutrien dan organik yang tinggi mempersulit pengolahan air minum di salah satu industri DKI Jakarta. Salah satu dampak dari memburuknya beban nutrien air baku adalah tingginya kandungan parameter amonium yang berakibat tidak efisiennya proses klorinasi. Hal ini membuat dibangunnya unit MBBR aerob, dengan tujuan menyisihkan kandungan amonium. Akan tetapi, unit MBBR aerob ini tidak berfungsi secara optimal. Masalah ini akan diatasi dengan mengalihfungsikan unit pra-sedimentasi yang ada menjadi unit MBBR anaerob secara pre-anoxik, sehingga dapat melengkapi proses penyisihan amonium yang terdiri dari nitrifikasi dan denitrifikasi. Tujuan dari modifikasi ini adalah mendapatkan efisiensi penyisihan amonium sebesar 90%. Metode yang digunakan pada perancangan ini dimulai dengan mengumpulkan data sekunder, lalu dilakukan perhitungan perancangan unit MBBR anaerob. Hasil perancangan menunjukkan bahwa dimensi yang dibutuhkan untuk unit MBBR anaerob ini adalah dengan ukuran panjang 18 m, lebar 7 m, dan kedalaman 9.5 m. Dengan efisiensi akhir diharapkan sebesar 90% untuk MBBR anaerob dengan konsentrasi akhir amonium diharapkan sebesar 1.05 mg.L-1.

Abstract

Domestic wastewater provides the largest contribution to pollution both in terms of quantity and quality. Therefore, before being discharged into the environment, wastewater needs to be managed first. This study used the cultivation of microalgae Chlorella Sp. and Algae Mix to manage domestic wastewater. The reactor used in the study was a 3L volume of water. The cultivation process was assisted by UV-A and UV-B with the air flow rate as much as 1.2L/min. Pollutant parameters being focused on were NH3-N and PO4-P nutrient parameters. Allowance for NH3-N by Chlorella sp. and algae mix are 54.9% and 49%, respectively. Allowance for PO4-P Chlorella sp. and algae mix is 70.2% and 57.1% while biomass increase of Chlorella Sp. and Algae Mix is 85.5% and 98.9%. Specific growth rate of Chlorella sp. and algae mix is 0.025 h-1 and 0.027 h-1. As a control on biomass growth, turbidity value in the study also increased.

Abstract

Domestic wastewater contains a high average nutrient ammonia-N (NH3-N) and total phosphate (PO43--P). This nutrient content has the potential to cause eutropication in water bodies. To prevent this eutropication, it is necessary to treat domestic wastewater. Currently, processing technology is needed that is useful for improving the quality of processed wastewater and a small amount of byproduct. One of these technologies is processing with a microalgae system, where the algae can be used to become biodiesel. Two types of microalgae that have the potential to produce biodiesel are Spirulina platensis and Nannochloropsis oculate. The cultivation of the two types of microalgae was carried out in the domestic wastewater media of Jakarta City by providing 24-hour lighting with UV-A and UV-B. The specific growth rates of Spirulina platensis and Nannochloropsis oculate were not much different, namely 0.0279 h-1 and 0.0282 h-1. The microalgae Spirulina platensis and Nannochloropsis oculate respectively reduced NH3-N nutrients by 82% and 80%, while PO43-P was 65.2% and 63.7%. The pH value during processing shows in the normal pH range. Total dissolved solids (TDS) in the processing process also decreased in a span of 48 hours.

Abstract

Asrama DLH Jagakarsa has a communal wastewater treatment plant (WWTP) that produces sludge that has not been treated. Asrama DLH residents directly apply the sludge from the communal WWTP as fertilizer for plants. Fecal sludge contains organic substances that provide nutrients to plants. However, there is a possibility that it still contains pathogenic bacteria and metals that can be harmful to plants. This research aims to utilize the fecal sludge from Asrama DLH Jagakarsa WWTP as organic fertilizer with additional ingredients in the form of humic acid. During fertilizer manufacturing, the bacteria and metals are removed. The analysis used includes the composting process conditions analysis, characteristics tests to determine the content of feces and fertilizers, and analysis of the application to plants. Analysis of the conditions in the composting process is the analysis of the pH value of organic fertilizers. Characteristic tests include soil variation (V1), WWTP sludge (V2), and organic fertilizer (V3). Analysis of the application of plant growth was carried out by testing the variation of soil 100% (P1), soil 80% + 20% fecal sludge (P2), and soil 80% + 20% organic fertilizer (P3). The laboratory analysis includes the analysis of nitrogen, phosphorus, potassium (NPP), and water content which will be compared with the quality standard of the Decree of the Minister of Agriculture Number 261 of 2019. The plant that is used as an indicator of the success of organic fertilizer in plant growth is the kale plant. The best value was obtained in the variation of organic fertilizer (V3), namely the NPP content and water content, respectively, which were 4.52%, 2.57%, 0.05%, and 19.84%. This shows that organic fertilizer increases NPP elements and plant growth.

Abstract

Wastewater available through the sewerage system can be reused as a daily need. With a sewer system, the Universitas Pertamina Area can utilize water according to Government Regulation of the Republic of Indonesia Number 82 of 2001 Class 4. Reuse of wastewater within this scope can improve sustainable development goals. This study aims to analyze the decision-making of sewerage water treatment so that it can be reused according to the class 4 quality standard. The first alternative consists of a collection tank, bar screen, pre-sedimentation, rapid sand filter (RSF), and disinfection. The second alternative consists of a collection tank, bar screen, horizontal roughing filter (HRF), RSF, and disinfection. The two alternatives provided have met the required quality standards. However, the area of land required in alternative one is too large compared to the second alternative. This causes the second alternative to be more appropriate to be applied in the Universitas Pertamina Area. Analysis of decision-making on the use of RSF media is carried out using the Analytical Hierarchy Process (AHP). The alternative media for RSF are sand, granular active carbon (GAC), and zeolite. The criteria for BOD removal, total coliform removal, cost, headloss, and replacement period of the most appropriate zeolite media for use in the RSF unit process.

Abstract

Indonesia merupakan penyumbang sampah plastik terbesar ketiga di dunia pada tahun 2020, dimana DKI Jakarta merupakan salah satu kota penyumbang sampah terbesar di Indonesia. Untuk menangani sampah plastik diperlukan kerjasama dari berbagai pihak, baik dari masyarakat, akademisi, pemerintah dan organisasi. Tanpa kontribusi publik, penanganan sampah terutama sampah plastik akan sulit. Tujuan kegiatan ini adalah untuk meningkatkan kesadaran masyarakat untuk memilah dan menangani sampah, sebagai upaya untuk meningkatkan kontribusi publik. Pada kegiatan ini, salah satu aplikasi pengelolaan sampah diperkenalkan dan dilakukan evaluasi usability untuk mengetahui seberapa mudah digunakan aplikasi tersebut. Kegiatan dilakukan pada 50 siswa salah satu Sekolah Menengah Negeri Atas Negeri (SMAN) di Jakarta Selatan. Hasil dari kegiatan ini menunjukkan bahwa siswa-siswa berminat untuk menggunakan aplikasi pengelolaan sampah, tetapi masih mengalami kesulitan dalam menggunakan aplikasi pengelolaan sampah. Selain itu, sebagai tindak lanjut dari penyuluhan ini, tempat sampah untuk memisahkan sampah plastik juga diletakkan di sekolah tersebut sebagai tindak lanjut dari penyuluhan ini.

Abstract

Urban public health initiatives rely heavily on community participation to ensure success and sustainability. This study explores the socio-demographic determinants of community engagement in the public health initiatives of Koja Subdistrict, Jakarta. A cross-sectional survey was conducted, employing both qualitative interviews and quantitative questionnaires to gather data from a representative sample. Binary logistic regression was used to analyze the data, focusing on aesthetics, public health sanitation performance, community socialization, gender, age, and education. The findings reveal that aesthetic considerations, perceived sanitation performance, socialization practices, and demographic factors significantly influence the willingness to participate. Aesthetics and community socialization positively impacted engagement, while perceived high sanitation performance paradoxically discouraged individual participation. Furthermore, demographic factors such as gender, age, and education level showed varying degrees of influence, with gender disparities and higher education correlating with increased engagement. This study contributes to understanding public health participation dynamics and offers insight into designing tailored community engagement strategies. Policymakers and health officials can leverage these insights to effectively enhance community involvement and address public health challenges.

Abstract

The increasing detection of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in domestic wastewater represents a pressing global environmental and public health challenge. Wastewater treatment plants (WWTPs), while designed to remove conventional pollutants, are increasingly recognized as reservoirs and hotspots for the persistence and horizontal gene transfer (HGT) of ARGs among microbial communities. This study aims to explore the mechanisms underlying bacterial antibiotic resistance, evaluate the limitations of conventional treatment processes –particularly disinfection methods such as chlorination – in effectively removing ARB and ARGs, and assess the implications for sanitation management in Indonesia. A systematic literature review (mini-review format) was conducted to synthesize recent findings on ARB/ARGs presence in WWTPs and the performance of existing treatment technologies. Results show that ARGs can persist even after disinfection, especially in extracellular forms, and that chlorination may, in some cases, promote ARGs release through cell lysis. Furthermore, several resistant strains demonstrate tolerance to standard chlorine doses. In Indonesia, where domestic wastewater treatment coverage and compliance remain inadequate, the uncontrolled discharge of partially treated or untreated wastewater exacerbates the spread of antibiotic resistance in aquatic environments. This study concludes that existing treatment systems are insufficient to address antibiotic resistance risks and emphasizes the urgent need for improved sanitation infrastructure, monitoring, and targeted treatment technologies.

Abstract

To better manage Jakarta's domestic wastewater, the DKI Jakarta Provincial Government commissioned the construction of Domestic Wastewater Treatment Plants (WWTP) in multiple locations across the city. After the results of the measurements have been determined, engineering work needs to order to address the numerous parameters more than excesses of the quality in addition, there. This study intends to develop a vertical flow CW design as an additional treatment for the DKI Jakarta Environmental Service Dormitory Communal Domestic WWTP as a recommendation for improvement so that the quality of treated water can meet domestic wastewater quality standards. This study aims to ensure that the quality of treated water can meet domestic wastewater quality standards. This redesign makes use of a variety of data sources, including primary data as well as secondary data. The necessary information is the quantity of constable water consumption and the quality of the domestic wastewater produced within the environment of the DKI Jakarta DLH Dormitory. Through a network of pipelines, wastewater from activities such as bathing and using the latrines is transported directly to the WWTP. During this time, water from activities such as washing and runoff caused by rain will enter various drainage channels to the receiving water body, the Ciliwung River. The length of the CW at WWTP 1 is 6.718 meters, and its width is 3.35 meters. Following more in-depth processing of the available data, it was discovered that the existing outlet wastewater had a low C/N ratio. When creating wetlands in the field using artificial CW, the discharge that flows into the wetland and the release that flows out of the wetland is not the same. The amount can either be decreased or increased according to the current circumstances. This needs to be considered for the presence of water in the swamp system to be managed. After being processed with VFCW, it was discovered that the total BOD value of the effluent produced was less than 30 mg/L. This suggests that the processing of VFCW can conform to the requirements of PermenLHK No. 68/2016, which is concerned with the Quality Standards for Domestic Wastewater. The ammonium-nitrogen value by comparing the molar mass value to NH3. As a result, WWTP locations 1, 2, and 3 have all achieved the required quality. The NH4 value, on the other hand, has not been able to meet the quality standard of PermenLHK No. 68/2016 concerning Domestic Wastewater Quality Standards. This is because the ammonia concentration from Domestic Communal WWTP 4 is so high. As a solution to this problem, WWTP 4 will be upgraded from four plants per square meter (ppm) to five plants per sq m (ppm), hoping to improve the rate at which plants absorb nutrients. The removal of ammonia using VFCW can range anywhere from 34 - 95 percent. Keywords: Domestic Wastewater, Planning, Constructed Wetland, WWTP

Abstract

Batik is a unique ethnic and heritage textile from Indonesia with low biodegradability (BOD5/COD) and demanding biological wastewater treatment. However, in its application a high biodegradability value is needed. To increase biodegradability the ozonation process can be used as pre-treatment. The purpose of this study is to determine the effectiveness of ozone pre-treatment in color removal, COD removal, and changes in biodegradability. This study was divided into two types of the reactor with a volume of 2 L and 16 L with each dose of 4 mg/min and 40 mg/min. The results of color removal in the reactor with a volume of 2 L showed a value of 85% for color removal and 34.6% for COD removal. The reduction in efficiency occurred in the color removal to 65% in reactor 16 L. The removal of COD with a volume of 16 L was not evenly distributed at each altitude of 43; 35; and 33% (50; 100; 150 cm). Biodegradability increased from 0.143 to 0,49 (2L reactor) and 0.4-0.45 (16L reactor), this allows for the application of higher biological wastewater treatment. Which the NH3-N and total phenol removal efficiencies of 12.9%-31.4% and 3-21.2%, respectively.
