Abstract

In the process of oil and gas production, it can produce large amounts of Naturally Occurring Radioactive Materials (NORM) with increased radioactivity as by-products. NORM disposal methods currently used in the oil gas industry are landfills, land-spreading, surface burial, underground injection, off-shore discharge. The biggest threat to groundwater caused by landfills is leachate. This study is a comparison of the leachate rates of Class I and Class II Landfill results using the Hydrologic Evaluation of Landfill Performance (HELP) modeling software developed by the United States Environmental Protection Agency (US EPA). For the operational phase, there were significant differences in leachate rate from the base layer between Class I and Class II landfills. For the phase after closure of waste, Class I and Class II landfills have the same performance in terms of holding back the rate of leachate.  ABSTRAKDalam proses produksi minyak dan gas dapat menghasilkan sejumlah besar Naturally Occurring Radioactive Materials (NORM) dengan konsentrasi radioaktivitas yang meningkat sebagai limbah hasil samping.

Abstract

AbstractRivers in Indonesia are heavily polluted by unmanaged municipal solid waste (MSW) which affects their capacity as drinking water, power, and irrigation sources. This research aimed to analyze the effect of MSW types and contact time on the dynamics of Chemical Oxygen Demand (COD) and ammonia in the waterthat was traced over two weeks period in a batch reactor filled with Ciliwung River organic and inorganic MSW samples. Then, the MSW degradation rates to COD and ammonia (k1) were mathematically analyzed by using the mass balance principle. The results showed that for organic MSW, there were rapid increasesin COD and ammonia concentrations on the first 6 days of the experiment and followed by steady decreases. In contrast, for inorganic MSW, overall steady trends were observed for both COD and Ammonia. The analysis of the degradation rate showed that the values of K1 for COD in organic MSW was ranging from3.841 to 4.655 /day, 10-30 times higher than those of inorganic MSW values, which ranged from 0.122 to 0.425 /day. For ammonia, the values of k1 for organic MSW ranged from 0.0021 to 0.0028 /day, about two times higher than those of inorganic MSW values ranging from 0.001-0.0014 /day. Findings in this studyoffer opportunities to model and simulate COD and Ammonia dynamics in surface water due to MSW contamination.Keywords: COD, ammonia, degradation, solid waste, time effect

Abstract

AbstractOne of the causes of river pollution is the presence of waste in water bodies which causes substantial water quality deterioration. The Ciliwung River is one of Indonesia's most polluted rivers with a very high level of pollution. This study aimed to estimate the amount of daily waste generation in water bodies and theircomposition characteristics. Waste samples were taken from segment 4 of Ciliwung River, namely Jalan Juanda Depok. The waste collection method uses a trawl boom and a trap net. The results showed that the average daily waste generation in the Ciliwung River is 323.87 kg/day (standard deviation of 366 kg/day), with the composition of waste dominated by organic waste as much as 68.63%, plastic waste 15.54%, textile waste 10.89%, and other waste 4, 54%. Fluctuating composition results may be caused by weather, sampling locations, and surrounding activities. The average waste generation in Ciliwung River in theliterature is 970 kg/day. The difference in estimates is because 33 illegal waste collection points along segments 5 and 6 of the Ciliwung River are suspected of leaking into the water body. The difference in estimates is also influenced by the percentage of unmanaged waste in DKI Jakarta which was about 0.9%.Keywords: waste generation, waste composition, trawl boom, Ciliwung, waste collection

Abstract

QUAL2K merupakan instrumen yang paling banyak digunakan dalam menyimulasikan kualitas air sungai di Indonesia. Untuk mengoperasikannya, QUAL2K membutuhkan input dari berbagai parameter dan variabel dengan jumlah banyak sehingga pengguna biasanya menggunakan nilai default untuk menyederhanakan proses simulasi. Namun, kesesuaian penggunaan nilai deafult ini pada kasus sungai di Indonesia belum pernah dievaluasi. Penelitian ini bertujuan untuk menganalisis sensitivitas nilai default untuk parameter dan variabel input terkait dengan simulasi Biochemical Oxygen Demand (BOD), Total Suspended Solid (TSS) dan Dissolved Oxygen (DO) di DAS Citarum Hulu. Analisis sensitivitas lokal dilakukan untuk 13 parameter dan 7 variabel input dengan memvariasikan setiap nilai default sebesar 5% dan sensitivitasnya dievaluasi dengan indeks sensitivitas (SI). Hasil analisis sensitivitas untuk simulasi BOD menunjukkan bahwa faktor koreksi suhu BOD dan konsentrasi DO dalam diffuse source merupakan parameter dan variabel input yang paling sensitif. Sedangkan untuk simulasi DO, beberapa parameter yang paling sensitif adalah Faktor Koreksi Suhu Oksigen, Lebar Sungai, Koefisien Manning dan Faktor Koreksi Suhu BOD. Variabel dan parameter input yang paling sensitif untuk konsentrasi TSS adalah konsentrasi DO dalam diffuse source dan fitorespirasi inhibisi oksigen.

Abstract

Jakarta is prone to pluvial, fluvial, and coastal flooding due to its geographical location and topography. In response to this problem, the Indonesian government has implemented several master plans, including the National Capital Integrated Coastal Development (NCICD). This ongoing program encompasses the construction of coastal and river embankment that stretch all over the coast of Jakarta. Since many coastal areas in Jakarta are residential or industrial, evaluating this performance of embankment has become crucial for effective flood management. The findings of this research can also support the development of other locations where NCICD embankment plan and enhance coastal resilience. Therefore, this research assessed the effectiveness of coastal and river embankment at Cengkareng Drain, a vital floodway in Jakarta, during extreme events that occur simultaneously. To simulate flooding events, two-dimensional HEC-RAS features were used to numerically calculate the area and depth of inundation. The simulation required geometry, terrain, land cover, and unsteady flow data. For the flow boundary conditions, a 100-year design rainfall, HHWL (Highest High Water Level), and 100-year design wave were considered to represent estuary conditions accurately. The simulation result showed that the maximum water level influenced by these factors was +3.145 mMSL, while the planned embankment top elevation was +3.40 mMSL. Furthermore, without the NCICD embankment, the simulation showed an inundation area of 1212.37 ha, which was reduced to 1111.22 ha after their implementation, leading to a decrease of 101.15 ha. This reduction significantly decreases potential damage to property and infrastructure, particularly in densely populated areas. The simulation also showed a reduction of 86.49 hectares or 66.22% in the inundation area with a depth exceeding 1 meter. These findings demonstrate the effectiveness of embankment in reducing the inundation area without any overtopping incidents.

Abstract

Processed fecal sludge generated from a sludge treatment plant rich of organic content, micronutrients, and several heavy metals that might potentially exist. Composting process recognized as a promising and cost-effective method to improve the sludge quality. The composting process was carried out in this study by using modified Compost Bag with processed sludge from fecal sludge treatment plant as the main material and organic waste and dry leaves as co-composting materials. The macro-micronutrients and heavy metal concentration of the produced compost were further analyzed. The potential application was also considered by indulging the risk assessment. The main and co-composting materials were investigated in three different ratios of processed fecal sludge (S), organic waste (OW), and dry leaves (DL) to get the optimum composition that meet the compost quality standard. Compost R2 with the ratio of 50S: 25OW: 25DL as an optimum composition which resulted good quality compost with the C/N ratio of 10.29, Total P2O5 about 2.45%, Total K2O of 0.38%, and the Cu removal up to 91.17%. The produced Compost R2 has met the compost quality standard with Hazard Quotient (HQ) for non-carcinogenic effects less than 1 revealed no potential for disease-causing effects thus safe to be used in daily life.

Abstract

Microplastics (MPs) are <5 mm synthetic polymer particles that are emerging contaminants and have been found widely in various water bodies. Wastewater treatment plants (WWTPs) play an important role in containing the release of MPs into the environment, but studies on the effectiveness of greywater-based WWTP, especially in dense urban areas such as Jakarta, are still limited. This research was conducted on a greywater WWTP with Moving Bed Biofilm Reactor (MBBR) technology in South Jakarta to analyze the abundance, efficiency of dispensation, and characteristics of microplastics based on shape, color, size, and material. Samples were taken from five points on weekdays and holidays, analyzed using NOAA methods and FTIR spectroscopy. The abundance of MPs at the inlet reached 942 particles/L (weekdays) and 675 particles/L (holidays), while at the outlet there were 290 particles/L and 211 particles/L, resulting in a dispensing efficiency of 69%. Five types of MPs (foam, fragment, fiber, film, microbead) were found with color variations (white-transparent, yellow, red, blue, green, black), as well as the content of PVFM, PVB, PVA, silicone, and POM polymers. This study contributes to the understanding of the distribution and character of MPs in greywater treatment systems that are still rarely explored, as well as supporting the development of mitigation strategies based on WWTP technology

Abstract

Household solid waste sampling is a critical part of solid waste management planning, as the results determine the design of the required infrastructure. However, the method suggested by the Indonesian national standard requires time and high costs, as it must be carried out for eight consecutive days. Hence, it is necessary to evaluate this requirement and design a more efficient sampling design without compromising the results. The study conducted solid waste sampling for 16 consecutive days from 31 middle-income households in Jakarta, the Capital City of Indonesia, resulting in a pool of 16 consecutive daily averages of solid waste generation per capita data. From this pool, we generated: (1) solid waste generation per capita from eight consecutive days, (2) six consecutive days, (3) four consecutive days, and (4) eight non-consecutive days data. The results showed that the average of solid waste generation per capita for datasets (1), (2), (3), and (4) are 0.505 (± 0.022) kg/day/cap, 0.495 (± 0.044) kg/day/cap, 0.501 (± 0.035) kg/day/cap, and 0.492 (± 0.02) kg/day/cap consecutively, indicating the same estimates of solid waste generation per capita can be achieved by four scenarios.
