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.

Abstract

The people of Lumajang District mostly use groundwater for sanitation hygiene purposes. The development of poorly planned residential areas has resulted in the existence of domestic wastewater management directly adjacent to the location of groundwater sources which causes the quality of groundwater not to comply with applicable quality standards. This study aims to determine the quality of groundwater from physical, chemical and microbiological parameters related to the existence of Communal IPAL in Lumajang District, Lumajang Regency. The determination of the groundwater sampling point was chosen at a location that had a distance of IPAL and was repeated twice. In this study, eight groundwater samples were taken with test parameters including pH, Fe, Mn, NO3, TDS, Color and total coliform which were then compared with Permenkes No. 2 of 2023 concerning Environmental Health. The results of the study showed that the quality of groundwater with a radius of IPAL did not meet the total coliform parameter in all samples, for the Fe parameter there were three samples that did not meet, for the Mn parameter two samples were found to not meet and for the TDS parameter two samples were found to not meet the applicable quality standards. The main factor causing the groundwater quality to be less than satisfactory is influenced by the technical aspect of communal wastewater treatment plant.

Abstract

Karawang Regional Public Hospital faces an increase in hazardous waste production due to an increase  in the number of patients and health services up to nine percent. The hazardous waste is no longer accomodated by their hazardous storage in the size of 8.00 x 3.00 m. The objective of the current study is to optimize the hazardous waste storage by rearranging the packaging and layout of the hazardous waste storage following the Minister of Environment Forestry Regulation No. 56 of 2015 and the Minister of Environment Forestry Regulation No. 6 of 2021. This research is a descriptive study using a qualitative approach. Hazardous waste production data is collected by sampling for eight days in accordance with Indonesian National Standard No. 19-3964-1994. Meanwhile, information about existing management and policies of hazardous waste at Karawang Regional Public Hospital were collected through observation and interview. The results showed that the average daily production of hazardous waste was 291.13 kg; 22.36 kg; 4.18 kg; and 30.77 kg for infectious, sharps, cytotoxic, and liquid medical, respectively. The optimization steps for hazardous waste storage include improving packaging, rearranging the layout by utilizing vertical space, and increasing the frequency of transportation by licensed transporter. The implementation of these steps can assist the hospitals in improving the effectiveness, safety, and cost efficiency hazardous waste management.

Abstract

Tofu as a protein food that is favored by the public causes the tofu industry to continue to increase. The tofu industry produces liquid waste that contains high organic matter and has the potential to pollute the environment if not treated. This study aims to determine the ability of activated carbon of palm shell and zeolite as filter media in Vertical Roughing Filter (VRF), in reducing BOD, COD, TSS parameters in tofu liquid waste. The research was carried out in three stages; first, sampling and initial analysis of tofu wastewater characteristics; second, preparing filter media through carbonization and activation; third, making a VRF circuit and treating tofu wastewater, then analyzing the final concentration. The research variables used were flow rate of 0.3 L/m; 0.5 L/m and contact time; 0.5 hours; 1 hour; 2 hours; 4 hours; 8 hours; 16 hours. The results showed that the filter media in VRF was able to reduce BOD, COD, TSS parameters in tofu liquid waste. The highest reduction efficiency was found at a flow rate of 0.3 L/m with a BOD value of 30.25% (contact time 0.5 hours); COD of 67.69 (contact time 1 hour); TSS of 81.56% contact time (0.5 hours). While the flow rate of 0.5 L/m, has a lower efficiency of reducing BOD, COD and TSS than the flow rate of 0.3 L/m. Overall, VRF is able to reduce the content of waste contaminants.

Abstract

The increasing volume of domestic wastewater due to population growth poses significant environmental challenges, requiring effective treatment solutions. This study evaluated the effect of aeration on the efficacy of Constructed Wetland-Microbial Fuel Cell (CW-MFC) system in treating domestic wastewater using Equisetum hyemale plant. Reactors with dimensions of 50 cm × 24 cm × 20 cm with a volume of 9 liters of wastewater were tested for 18 days using 8 fed-batch reactors with gravel media and graphite electrodes, with NaCl as the electrolyte solution and KCl salt bridge. Lactobacillus plantarum was used to assess the removal efficiency of Biologycal Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and pH. The results showed the CW-MFC system significantly reduced pollutants, with the highest removal rates in reactors E7 and E8 in all treatments with BOD removal efficiences 90% and 91%, COD removal efficiencies of 93% and 91% on day 15.  TSS removal efficiency of E7 was 60% and E8 was 64%. Removal pH was 25-33%.  The highest bioelectricity production was highest in reactor E7 at 990.8 mW/m² on day 15 then gradually decreased to 520 mW/m² on day 18 due to the synergistic interaction of microbes, plant aeration, and electrochemical processes. This study concludes that CW-MFC with aeration with the addition of bacteria provides the best results and can be a sustainable solution in wastewater management and clean energy.

Abstract

Clean water in Kupang City has decreased in quantity by 30-50% with yellowish water quality and contains 45/100 ml of Collifom and E.coli bacteria that can cause diarrhea, salmonellosis, leptospirosis, hepatitis. One of the causes of the decrease in water quantity and quality is climate change, as well as extreme weather so that the available raw water sources are not sufficient to meet domestic needs, while 80% of clean water use comes from domestic sources. Therefore, it is necessary to utilize domestic wastewater through a coagulation-flocculation process using natural coagulants from Moringa seeds and papaya seeds which function as flocculants, reduce the characteristics of chemical contaminants, stabilize colloidal particles and absorb dissolved organic matter and are safe for human health and the environment. Research on the development of moringa seed and papaya seed biocoagulants needs to be done because they are very effective in reducing the concentration of pollutants and are economical. The research method is through laboratory analysis, TOPSIS analysis and proximate analysis to determine the levels of water, oil and fat, protein to produce pure coagulants. Then optimization of the coagulation-flocculation process with jar tests using TOPSIS analysis to determine the optimum conditions with a coagulant dose of 110 mg/L, a fast stirrer of 200 rpm for 1 minute, a slow stirrer of 60 rpm for 20 minutes, and a settling of 15 minutes with a percentage reduction using Moringa seeds and papaya seeds of 31.25% - 98.81% in TSS, Phosphate, Ammonia, Oil and Fat, Coliform.
