Abstract

Lemna minor plant have the ability to reduce pollutant levels in Landfill leachate. The use of Lemna minor in leachate treatment was considered effective in degrading Cd and COD pollutants. The objective of this study was to determine the effectiveness and absorption rate of Lemna minor in degrading heavy metal Cd and reducing COD levels in Gampong Jawa Landfill leachate. This study used the phytoremediation method on a laboratory scale, and the leachate sampling method used the grab sampling technique. In testing both parameters, two types of test variations were carried out. First, in Reactor I, it was carried out without using an aerator, and in Reactor II, the test was carried out with the addition of an aerator. For duration, the variations of retention time were used are the third, sixth, ninth, and 12th days. The weight of the Lemna minor were used in each reactor was 35 grams for a leachate volume of 5 Liters. The results showed that Lemna minor was able to reduce pollutant levels in the Gampong Jawa Landfill leachate with the most optimal proportion of 15.92% for the heavy metal Cd, and 94.68% for the organic pollutant COD. Treatment on the 12th day for tests carried out in reactors that have an aeration system was the most effective variation in reducing the levels of Cd and COD parameters.

Abstract

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.

Abstract

Air limbah Rumah Pemotongan Ayam (RPA) terlebih dahulu harus diolah sebelum dibuang ke badan air. Penelitian ini bertujuan untuk menurunkan kadar pencemar dalam air limbah RPA sesuai dengan baku mutu air limbah. Dalam penelitian ini dilakukan proses pengolahan air limbah RPA secara koagulasi-flokulasi dengan menggunakan biokoagulan ekstrak kulit singkong untuk menurunkan kadar pH, kekeruhan, TSS dan COD pada limbah RPA. Hasil penelitian menunjukkan bahwa dosis biokoagulan ekstrak kulit singkong berpengaruh terhadap perubahan parameter pH, kekeruhan, TSS dan COD. Pengujian dilakukan dengan memvariasikan dosis biokoagulan yaitu 0 ml, 5 ml, 10 ml, 15 ml, 20 ml dan 25 ml. Hasil penelitian menunjukkan bahwa penurunan nilai pH, kekeruhan, TSS dan COD paling optimum terjadi pada dosis biokoagulan 5 ml. Dosis biokoagulan sebanyak 5 ml mampu menurunkan nilai pH menjadi 7,5, menurunkan nilai kekeruhan menjadi 172,7 NTU dengan efisiensi sebesar 60,48%, menurunkan kadar TSS menjadi 220 mg/L dengan efisiensi 69,01% dan menurunkan COD menjadi 1.279 mg/L dengan efisiensi 34,97%. Biokoagulan ekstrak kulit singkong dapat menurunkan parameter pencemar pada limbah cair RPA, namun penurunan yang memenuhi baku mutu hanya pada parameter pH dan untuk parameter kekeruhan TSS dan COD mengalami penurunan namun belum memenuhi baku mutu air limbah RPA yang telah ditetapkan oleh Peraturan Menteri Lingkungan Hidup Republik Indonesia No. 5 tahun 2014 Tentang Baku Mutu Air Limbah.

Abstract

Pengabdian kepada masyarakat merupakan salah satu dari Tri Dharma perguruan tinggi bagi masyarakat. Air cucian beras dan juga limbah dapur merupakan sampah organik yang jarang dimanfaatkan sebagai salah satu alternatif pupuk yang ramah lingkungan. Sebagian besar sampah dapur dapat dijadikan pupuk kompos maupun pupuk cair. Tujuan dilakukan pengabdian ini adalah untuk memberikan edukasi bagi masyarakat tentang pemanfaatan limbah dapur dan juga air cucian beras sebagai salah satu unsur hara alami bagi tanaman. Dengan cara ini diharapkan dapat mengurangi sampah organik rumah tangga. Metode yang digunakan dalam pengabdian ini berupa pemberian penyuluhan dan praktek pembuatan pupuk. Bahan yang digunakan berupa air cucian beras, gula merah dan juga sisa sampah dapur. Campuran tersebut difermentasi selama 7-10 hari. Selama proses ini berlangsung, tutup wadah dibuka sesaat untuk mengurangi kebocoran wadah akibat gas-gas hasil fermentasi yang dihasilkan oleh bakteri. Hasil fermentasi air cucian beras dan juga limbah dapur setelah 7-10 hari berwarna kecoklatan dan berbau sedikit asam. Hasil pengabdian ini berupa pupuk organik cair yang siap diaplikasikan bagi tanaman. Pengaruh pemberian pupuk terhadap tanaman belum dilakukan karena keterbatasan waktu dan akan dilakukan survei pada agenda kegiatan pengabdian berikutnya di Desa Lamreh.

Abstract

This study assesses drinking-water and clean-water quality and sanitation conditions at Dayah Inti Darul Aitami, West Aceh, to support healthier boarding-school environments. A mixed-methods case study was conducted, combining laboratory water-quality testing with field observation/interviews and an exploratory questionnaire of 10 santri. Laboratory results show that Reverse Osmosis (RO)-treated drinking water met key benchmark parameters (turbidity 0.45 NTU, TDS 14 mg/L, pH 6.68) and showed “Not Detected” results in the H₂S pathogen indicator test at both 1×24 h and 3×24 h incubation. In contrast, borehole-derived clean water exceeded the TDS benchmark (412 mg/L) and showed “Detected” results for the H₂S pathogen indicator test at both incubation periods. Questionnaire responses were consistent with these patterns: 8/10 respondents rated drinking-water quality as satisfactory, whereas only 5/10 rated clean-water quality as acceptable, citing odor and discoloration. Sanitation challenges were also reported, particularly inadequate toilet cleanliness (3/10 respondents) and suboptimal solid-waste management (4/10 respondents). Overall, while access to water sources is adequate, improvements are needed in clean-water treatment and source protection, routine monitoring, and sanitation management to reduce health risks and strengthen Eco-Dayah implementation.

Abstract

This study compared drinking-water quality, general-use water quality, sanitation conditions, and water, sanitation, and hygiene (WASH) service levels in three Islamic boarding schools (dayah) in Aceh Province, Indonesia. An exploratory multi-site mixed-methods design combined six point-of-use water samples, site observation, management interviews, and questionnaires administered to 10 students at each site. Water quality was assessed using pH, turbidity, total dissolved solids (TDS), and H₂S screening at all sites, while culture-based Escherichia coli and Total Coliform testing was conducted at only one site because of laboratory capacity constraints. Service performance was evaluated using an adapted WASHCost framework covering quality, quantity, accessibility, and reliability. Drinking water generally met the study reference ranges for pH and turbidity, but TDS exceeded the operational threshold of 300 mg/L at Al-Muslimun (400 mg/L) and Darul Aman (548 mg/L). General-use water showed the clearest cross-site weakness: H₂S screening was positive at 24 and 72 hours at all three dayah. Darul Aman recorded high turbidity (6.59 NTU) and TDS (1,051 mg/L), and Al-Muslimun showed a Total Coliform Count of 151 CFU/100 mL in general-use water, with E. coli non-detectable. Student perceptions were generally positive, indicating a perception-risk gap. Under the adapted WASHCost assessment, Al-Muslimun and Darul Ulum were classified as intermediate, whereas Darul Aman was classified as substandard. These findings suggest that dayah WASH improvement should prioritize the protection and routine monitoring of general-use water systems, not only treated drinking-water points.
