Abstract

ABSTRAKPenelitian ini menyelidiki pengaruh penambahan glukosa, fruktosa dan sukrosa terhadap pengolahan air buanganrumah tangga dengan proses mikroba anaerobik menggunakan reaktor batch. Parameter yang diamati adalahCOD (Chemical Oxygen Demand), TSS (Total Suspended Solid), VSS (Volatile Suspended Solid) dand volumebiogas. Proses pengolahan dievaluasi dari jumlah polutan yang berkurang dan jumlah biogas yang terbentuk.Tiga jenis gula dengan kisaran konsentrasi yang bervariasi ditambahkan ke lumpur sebelum proses pengolahanair buangan. Proses pengolahan itama adalah proses fermentasi gelap anaerobik, dengan reaktor aerobikdiguncang di atas shaker pada kecepatan 200 rpm.Ph diatur menjadi 5 dan suhu 30oC. Hail menunjukkan bahwaglukosa dengan jumlah biakan bakteri 20%, dan konsentrasi guil 2% adalah substrat tambahan yang pling efisien,mengurangi kadar COD hampir 100%. Volume biogas yang dihasilkan 9,5 mL dan TSS serta TSS adalah 37 mg/Ldan 460 mg/L.Kata kunci: glukosa, sukrosa, fruktosa, substrat, pengolahan air buanganABSTRACTThis research investigate effects of addition of glucose, sucrose dan fructose to the sewage wastewater treatmentprocess by anaerobic microbial process using batch reactor. The observed parameters are COD (ChemicalOxygen Demand), TSS (Total Suspended Solid), VSS (Volatile Suspended Solid) and volume of biogas. Thetreatment process was evaluated by reduction of pollutant and biogas production. Three types of sugar at a rangeof concentration was added to the sludge prior to wastewater treatment . The main treatment was anaerobic darkfermentation process, shaken at 200 rpm. pH was set to be 5 and temperature was 30oC. The results shows thatglucose at 20% inoculum size and 2% sugar concentnration in the most efficient substrate, reduced COD to almost1005. The volume of biogas produced is 9.5 mL, and TSS and VSS were 37 mg/L and 460 mg/L respectively.Keywords: glucose, sucrose, fructose, substrate, wastewater treatment

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

Rapid population growth and climate change have put pressure on water availability, leading to a water crisis. Efforts to control water resources are needed to address this. The option of using domestic wastewater treatment plant effluent has emerged as an alternative solution. In 2024, the Jambi City Wastewater Treatment Plant (WTTP) infrastructure will be constructed and operated with a capacity of 7,500 m^3/day using Moving Bed Biofilm Reactor (MBBR) treatment technology. The existing WTTP is considered to have great potential in terms of volume. However, it is still unknown how much this potential can contribute to meet the water demand of Jambi City. Therefore, this research was conducted to fill this information gap. The research was conducted using the descriptive statistics method with quantitative and qualitative approaches. The analysis of population growth projections and public facilities refers to the Minister of Public Works Regulation No. 18/PRT/M/2007. There are 5 (five) categories of water demand analysed, namely: (a) domestic; (b) general; (c) landscape irrigation; (d) agricultural irrigation; and (e) fisheries. The potential use of wastewater is obtained by comparing the existing wastewater discharge with each category and application of water demand. The results of the analysis show that the effluent from the Jambi City WWTP can contribute 100% to meet the water demand of the domestic category (public taps), public, landscape irrigation and fisheries. In contrast, the domestic category (house connections) can only contribute 11% and the agricultural irrigation category can only contribute 15%.

Abstract

Coal ash from the Sawahlunto City coal mine is used to backfill former mine land. This application poses a clear threat to groundwater quality. The objective of this study is clear: to analyze the concentration of heavy metals, including Ni and Cu, and their distribution in groundwater around the coal ash landfill area using response surface methodology in design of experiments. Groundwater samples were taken three times at four locations spaced 0 m, 365 m, 730 m, and 850 m by guiding SNI 6989.58.2008. Laboratory tests of metal concentrations refer to SNI 6989-84:2019. Water quality analysis showed Ni concentration exceeded drinking water quality standards with a measured concentration of 0.227 mg/L, while Cu parameters were still within safe limits with concentrations of 0.0002 mg/L and 0.02 mg/L. The metal distribution analysis definitively showed that coal ash landfilling in the former mining area contributed to groundwater pollution by Ni. The distribution pattern of Ni and Cu decreases with increasing distance. It is imperative that the FABA landfill area be located away from settlements that use groundwater to protect consumers. Further research is needed to determine the safe distance between the coal ash landfill site and groundwater sources.
