Changes in land use cause to reduced water absorption. Aceh Province is one of the areas that does not yet have technical regulations that have been implemented in terms of increasing water infiltration. This is one of the causes of not optimal flood handling. In urban areas, for example in the capital of Aceh Province, namely Banda Aceh, floods still occur frequently when there is high rainfall intensity and long duration of rain. One of the villages that experienced inundation was Gampong Lamteh, Ulee Kareng District, Banda Aceh. One solution to this problem is the construction of environmentally sound drainage in the form of infiltration wells. The existing drainage channels in Gampong Lamteh Banda Aceh are currently only located at a few points to drain excess water into water bodies while the rest are still ground canals. The cause of inundation is due to the unavailability of rainwater infiltration sites. After planning, the infiltration discharge value obtained by the infiltration wells is 0.000006594 m3/second and the total storage volume is 70,650 m3 and the design of the infiltration wells is planned in the form of a circle with a well height of 3 m, radius 0.5 m radius and the planned number of wells is 30 wells.

The Wastewater from fish processing contains highly organic pollutants, causing pollution to water bodies. Electrocoagulation method is utilised in fisheries wastewater treatment because of its simple and easier to do and also effective in removing pollutants. This research uses an experimental method with a quantitative approach by using dependent variables such as COD, BOD, ammonia, TSS and pH and independent variables such as electrical voltage of 3, 5 volts and contact time of 60, 90 and 120 minutes. The results of the electrocoagulation process using Al and Fe electrodes showed the effectiveness of reducing the concentration of COD, BOD and TSS values by 96.34%, 95.2% and 73.22% with the maximum voltage of 5 volts and a contact time of 120 minutes. The effectiveness of reducing ammonia concentration occured at the optimum voltage of 3 with a contact time of 60 minutes, which was 98.75%. The pH concentration increased from acidic to alkaline. Based on the results of this study, the amount of voltage in the electrocoagulation method can affect the concentration of COD, BOD, ammonia and TSS contained in wastewater from fish processing. The results obtained show the quality of wastewater in accordance with predetermined quality standards.

The majority of tofu manufacturers lack the necessary infrastructure to treat wastewater, resulting in the direct discharge of wastewater into water bodies. Such practices have the potential to results in environmental pollution. This study examines the efficacy of combining anaerobic biofilter technology and pre-aeration with a microbubble generator for the treatment of wastewater generated by the tofu industry. The research focused on the impact of hydraulic retention time (HRT) on the reduction of pollutants, specifically chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS), and pH levels. The results indicated that prolonged HRT in the anaerobic biofilter significantly reduces pollutant concentrations. 48-hour HRT achieved reductions of 80.78% for COD, 78.53% for BOD, and 89.25% for TSS, respectively. The integration of a microbubble generator further enhanced treatment efficiency. The combination of a 48-hour anaerobic biofilter and a 180-minute microbubble generator achieved reductions of 93.82% for COD, 93.11% for BOD, and 97.5% for TSS. The effluent consistently met the pH quality standards set by the Indonesian government. The findings suggest the potential for optimizing retention times and combining anaerobic and aerobic treatments to address wastewater challenges in the tofu industry.

High COD levels in abattoir wastewater might cause negative impact to the environment, hence it must be lowered before being discharged into the environment. The seeds of moringa plant (Moringa oleifera) contains quite high levels of protein compounds, makes it potential as biocoagulant in coagulation-flocculation process for wastewater treatment. The objective of this research is to discover the potential of biocoagulant from moringa seeds powder in decreasing COD levels on abattoir waste water treatment. The research was performed with biocoagulant dose variations 0 g; 0.5 g; 1 g; 1.5 g; 2 g; and 2.5 g, utilizing rapid mixing at 120 rpm, and slow mixing at 30 rpm with duration 2 and 30 minutes respectively. The result showing that the optimum dose obtained at 2 g, with percentage of decreation by 93.97%. Based on the research, it is concluded that the biocoagulant derived from moringa seeds can perform effectively in COD removal of abattoir wastewater treatment.

Industri pupuk urea menghasilkan limbah yang mengandung amonia (NH3) yang bersifat racun sehingga jika dibuang langsung ke lingkungan dapat mencemari lingkungan dan merusak ekosistem. Salah satu metode yang digunakan untuk menurunkan kadar amonia (NH3) adalah metode Moving Bed Biofilm Reactor (MBBR) yang merupakan metode pengolahan biologis yang menggunakan media Kaldness sebagai tempat pengembangbiakan mikroorganisme atau tempat pembentukan biofilm. Tujuan dari penelitian ini adalah untuk mengetahui efektifitas dari metode Moving Bed Biofilm Reactor (MBBR) dalam mendegradasi parameter Amonia (NH3), pH, TSS, dan COD pada limbah industri pupuk urea. Penelitian ini menggunakan variasi media dalam reaktor sebanyak 30% dan 50% dari volume limbah dengan variasi waktu kontak selama 24 jam, 48 jam dan 72 jam. Penurunan kadar parameter pH tertinggi terjadi pada variasi waktu 24 jam dengan variasi media sebanyak 50% yaitu 8,5 dari konsentrasi awal 9,1. Kadar TSS semakin meninggi pada variasi waktu 72 jam dengan media sebanyak 50% yang dari kadar awalnya 16 mg/l menjadi 474 mg/L. Penurunan kadar COD tertinggi terjadi pada waktu 72 jam dengan variasi media 0% pada reaktor kontrol yaitu dari nilai awal 243 mg/L menjadi 5 mg/L. Sedangkan penurunan kadar polutan amonia (NH3) tertinggi terjadi pada variasi waktu 72 jam dengan variasi media sebanyak 50% dengan kadar awal 112,04 mg/L menjadi 86,53 mg/L. Maka metode MBBR efektif pada pengolahan parameter Amonia (NH3), pH, TSS, dan COD kecuali pada parameter TSS.

Leachate is a liquid containing hazardous materials such as metal Iron (Fe). One method that can be used to reduce Fe levels in leachate is using the bioremediation method. This study aimed to determine the absorption ability of Pseudomonas aeruginosa bacteria in remediating Fe as well as the physical and chemical characteristics of leachate such as COD, TSS, and pH before and after using P. aeruginosa. This study used an experimental method of four treatments and three replications. The concentration of bacteria used was 108 CFU/ml with ex-situ contact times of 0, 10, 20, and 30 hours. The results showed that the highest decrease in Fe, COD, TSS, and pH occurred at 30 hours. The Fe value can be reduced to 4.45 mg/L with an absorption effectiveness of 38.19%; the initial COD value of 1.432 mg/L decreased to 1.301 mg/L. In addition, the TSS value decreased to 213 mg/L from the initial level of 223 mg/L and the highest pH decreased, namely 9.6 to 8.1. The uptake of P. aeruginosa bacteria is good in reducing acceptable levels of Fe and pH.

Air limbah domestik di Perumahan Lam Trieng Madani, Kuta Baro, Aceh Besar, hanya ditampung pada cubluk atau dialirkan langsung ke drainase. Berdasarkan PerMenLHK No. 68 Tahun 2016 tentang Baku Mutu Air Limbah Domestik, air limbah domestik dari rumah tangga berpotensi mencemari lingkungan sehingga perlu dilakukan pengolahan sebelum dibuang ke media lingkungan. Penelitian ini bertujuan untuk mengidentifikasi karakteristik air limbah domestik dan merencanakan desain IPALD. Teknologi yang digunakan yaitu bak ekualisasi, bak sedimentasi, dan CW tipe SSF. CW dikenal sebagai teknologi yang cukup kompleks dalam mengolah air limbah dan memiliki nilai estetika sehingga menjadikan CW sangat sesuai diterapkan di lingkungan pedesaan. Hasil uji laboratorium didapatkan karakteristik air limbah domestik parameter TSS dan total coliform yang melebihi baku mutu sebelum dilakukan pengolahan. Perencanaan ini menyisihkan TSS 89% dan total coliform 48%. Hasil perhitungan unit pengolahan disajikan dalam bentuk gambar desain dan total luas lahan yang dibutuhkan yaitu 97,75 m2.
