Abstract

Anaerobic digestion is to treat organic waste such as vegetable solid waste (VSW). Anaerobic co-digestion is the mixture of two or more different waste types with the aim to enhance the efficiency of the anaerobic digestion process. In this study, anaerobic digestion of vegetable solid waste (VSW) is compared to the anaerobic co-digestion of VSW and sequencing batch reactor (SBR) sludge. This investigation is focussed  on the varying the organic loading rate (OLR) which is the mixing ratio of VSW to SBR sludge; and pH (6, 7 and 8) of the mixture. The mixtures were kept in serum bottles and placed in a shaker for 7 days at 150 rpm. Experiments with OLR 2:1, VSW composition of 1:2:1:1 and pH 6 produced the highest total biogas in anaerobic co-digestion. Thus, for anaerobic co-digestion, the optimum composition of VSW, OLR and pH are 1:2:1:1, 2:1 and 6 respectively. The range of % reduction in total solids (TS), total suspended solids (TSS) and total dissolve solids (TDS) in anaerobic co-digestion is 4-46, 0-43 and 0-64 respectively. In a comparison with single digestion, only 1 in 5 samples of co-digestion exceed that amount of biogas produced by single digestion and this shows that single anaerobic digestion resulted in higher biogas yield. The range of % reduction in TS, TSS and TDS in anaerobic digestion is 13-54, 15-66 and 9-58 respectively. Comparatively, single digestion performs better in solids removal than anaerobic co-digestion and thus, co-digestion method may not be suitable for all types of organic waste.

Abstract

Anaerobic ammonium oxidation (anammox) is the process of converting ammonium directly into nitrogen gas with nitrite as an electron acceptor under anaerobic conditions. This process is more effective than conventional nitrification-denitrification but is very dependent on several parameters, one of which is temperature. The optimum temperature range for the growth of anammox bacteria is 30-400C. The purpose of this research was to determine the efficiency of nitrogen removal by anammox process using palm fibers in the Up-Flow Anaerobic Sludge Blanket (UASB) reactor in the tropical temperature. The experiment was conducted at a laboratory scale with a variation of Hydraulic Retention Time (HRT) 24 h and 12 h using artificial wastewater. The reactor was inoculated with anammox granule genus Candidatus Brocadia. The concentration of ammonium, nitrite, and nitrate in the influent and effluent were measured using a UV-Vis spectrophotometer based on standard method. Based on the experiment, the ratio ΔNH4+-N:ΔNO2--N and ΔNO3--N:ΔNH4+-N similar with stoichiometric of anammox. The maximum Nitrogen removal performance (NRT) achieved 0.11 kg-N/m3.d at Nitrogen Loading Rate (NLR) 0.14 kg-N/m3.d and 0.20 kg-N/m3.d at NLR 0.29 kg-N/m3.d. The removal efficiency for Ammonium Conversion Efficiency (ACE) and Nitrogen Removal Efficiency (NRE) in HRT 24 h were 79% and 76%, respectively while decreased in HRT 12 h were 72% and 69%, respectively. Anammox process can be applied in the tropical temperature at a laboratory scale using a UASB reactor with palm fiber as the carrier.

Abstract

This study aims to identify the water quality of the Krueng Brayeun River as one of the potential surface waters to meet the needs for the development of a Drinking Water Supply System (SPAM) in Banda Aceh City and Aceh Besar District. Water samples were taken at five locations around the planned intake, namely two points before the planned intake and three points after the planned intake. Laboratory tests were carried out on physical, chemical, and biological parameters. Based on the test results, it is possible to use the proposed intake location as a source of raw water for PP RI No. 22 of 2021 class I. There is no possibility of pollution at the site of the proposed intake, and water-related activities that are carried out close to bends do not have an impact on the river of quality Kr. Brayeun. Recommendations for securing raw water sources are needed so that the utilization of Krueng Brayeun River water does not interfere with the PDAM's processing process.

Abstract

This study aims to determine the efficiency of organic removal in the form of Chemical Oxygen Demand (COD), Nitrate (NO3), and TSS of tofu wastewater with electrocoagulation process of aluminum electrode pairs with the monopolar arrangement. A two liters batch reactor and aluminum electrode (aluminum content of 95.7%) were used. Variations in current density (21 - 104 A / m2) and contact time (2 - 60 minutes). The optimum conditions were obtained at a current density of 104 A / m2 in 10, 15, and 2 minutes for COD, NO3, and TSS, respectively. The optimum removal efficiency for COD, NO3, and TSS were 95%, 69.64%, and 99.99%, respectively at a current density of 104 A/m2. Increases in current density and contact time were directly correlated with improvements in COD, NO3, and TSS removal effectiveness. The pH of wastewater has increased to 8.5. While the temperature of wastewater only increased in the 2nd minute to 27°C. Meanwhile, conductivity in wastewater decreases with increasing contact time. The decrease in conductivity is inversely proportional to the efficiency of pollutant reduction. The effluent of the results of this study has met the quality standards of Minister of Environment Regulation No. 5 of 2014 Attachment XVIII concerning Wastewater Quality Standards for Soybean Processing Businesses and/or Activities.Keywords: COD, electrocoagulation, aluminum electrodes, tofu wastewater, monopolar.ABSTRAKPenelitian ini bertujuan menentukan efisiensi penyisihan senyawa organik berupa Chemical Oxygen Demand (COD),Nitrat (NO3), dan Total Suspended Solid (TSS) air limbah pabrik tahu dengan proses elektrokoagulasi pasangan elektroda aluminium dengan susunan monopolar. Penelitian menggunakan reaktor batch dua liter dan elektroda aluminium (kandungan aluminium sebesar 95,7%). Variasi yang dilakukan adalah variasi rapat arus ( 21 - 104 A/m2) dan waktu kontak (2 – 60 menit). Kondisi optimum diperoleh pada kerapatan arus 104 A/m2 selama 10, 15, dan 2 menit untuk masing-masing COD, NO3, dan TSS. Efisiensi penyisihan optimum untuk COD, NO3 dan TSS masing-masing sebesar 95%, 69,64% dan 99,99 % pada rapat arus 104 A/m2. Peningkatan efisiensi penyisihan COD, NO3 dan TSS berbanding lurus dengan peningkatan rapat arus dan waktu kontak. pH air limbah mengalami peningkatan hingga 8,5. Temperatur air limbah hanya meningkat pada menit ke-2 menjadi 27°C. Sementara itu konduktivitas pada air limbah menurun seiring dengan bertambahnya waktu kontak. Penurunan konduktivitas berbanding terbalik dengan efiisiensi penyisihan polutan. Efluen hasil penelitian ini telah memenuhi baku mutu Peraturan Menteri Lingkungan Hidup No 5 Tahun 2014 Lampiran XVIII tentang Baku Mutu Air Limbah Bagi Usaha dan/ atau Kegiatan Pengolahan Kedelai.

Abstract

The growth of illegal shrimp ponds in Batang Anai, Padang Pariaman Regency has been very widespread recently. This is because the advantages of shrimp cultivation include fast growth, high survival rate, high shrimp appetite, greater resistance to disease attacks and relatively short rearing time, namely 90-100 days per cycle. As shrimp cultivation develops in this area, environmental pollution problems arise. Of course, this is contrary to Law number 36 of 2009 concerning Health, Article 4 and Article 6 states that everyone has the right to health and everyone has the right to a healthy environment for achieving a level of health. Based on preliminary interviews with the community around the shrimp ponds, it was stated that the existence of illegal shrimp ponds does not take into account the impact on the environment, and even disturbs the community. Meanwhile, there is no action by the district or local government to control or manage the impacts, so various efforts are needed to restore optimal health status for the surrounding community.

Abstract

This study evaluates the efficiency of water usage in the Department of Environmental Engineering at Universitas Andalas (Unand) by analyzing water consumption volume, identifying potential leaks, and comparing the findings with applicable standards for laboratories and offices. A 1.5-inch water meter was installed at the outlet of the rooftop reservoir on the 4th floor to measure water usage volume, and manual attendance devices were used to record the number of water users in the office and laboratory. Leakage testing was performed using the step test method, where water flow was stopped for 16 hours overnight to monitor changes in the water meter readings, with results indicating no leakage. The study found that the highest water consumption was 39.66 L/person/day in the laboratory and 55.06 L/person/day in the office. Water consumption in laboratories was found to be 100-200 L/person/day according to the standard, while water use in offices slightly exceeds the Indonesian National Standard (SNI) 03-7065-2005 of 50 L/person/day. The study recommends implementing water conservation technologies, such as automatic faucets and dual-flush toilet systems, to reduce water consumption and enhance water efficiency.
