Abstract

The problem of household organic waste remains an environmental issue that requires effective management in various regions, including Jelu Village. This community service activity aims to increase active community participation in organic waste management through the use of Black Soldier Fly (BSF) larvae. BSF cultivation technology was chosen because it can quickly decompose organic waste and produce by-products in the form of animal feed and organic fertilizer. This program was implemented through an educational approach, technical training, and direct mentoring for residents from several neighborhood units (RT) in Jelu Village. The results of the activity showed an increase in community knowledge and skills in BSF cultivation, with maggot production reaching 2 kg in three weeks and daily organic waste management of around 4–5 kg. Furthermore, the community was also able to independently build cultivation cages. This activity has succeeded in raising ecological awareness while providing economic benefits, and is expected to become a model for sustainable organic waste management at the village level.

Abstract

Air limbah rumah sakit mengandung mikroorganisme patogen, bahan kimia beracun, dan zat radioaktif yang berbahaya bagi kesehatan dan lingkungan. Rumah Sakit X merupakan rumah sakit tipe C dengan luas lahan 10.022 m², luas bangunan 44.898 m², dan 173 tempat tidur, menghasilkan air limbah dengan parameter TSS, BOD5, COD, amonia, fosfat, dan E. coli. Berdasarkan hasil pengujian Januari 2024 pada outlet Instalasi Pengolahan Air Limbah (IPAL), tiga parameter mendekati batas baku mutu SK Gubernur Jawa Timur No. 72 Tahun 2013. Kondisi ini dipengaruhi oleh IPAL yang telah beroperasi bertahun-tahun dan pembangunan gedung baru yang meningkatkan beban pengolahan. Penelitian ini bertujuan untuk mengetahui karakteristik air limbah dan air hasil pengolahan serta menganalisis efektivitas kinerja IPAL Rumah Sakit X dalam mengelola air limbah agar aman bagi masyarakat dan lingkungan. Sampel diambil menggunakan metode grab sampling pada inlet dan outlet dengan volume 2000 mL. Hasil laboratorium menunjukkan parameter amonia (0,22 mg/L) dan fosfat (2,922 mg/L) tidak memenuhi baku mutu, disebabkan kurangnya waktu aerasi yang menyebabkan kadar oksigen terlarut rendah dan menghambat mikroorganisme dalam menguraikan NH3 dan PO4. Parameter E. coli (350 MPN/100 mL) memenuhi standar baku mutu. Perhitungan efektivitas menunjukkan penurunan E. coli signifikan sebesar 96,23%, menandakan keberhasilan desinfeksi. Namun, penurunan amonia hanya 45,89% dan masih melebihi batas baku mutu, sedangkan fosfat mengalami peningkatan dengan efektivitas -6,22%, mengindikasikan kegagalan pengolahan fosfat. Hasil ini menyoroti perlunya optimalisasi proses aerasi dan pengolahan fosfat pada IPAL Rumah Sakit X.

Abstract

Leachate generated from landfill disposal sites poses a serious environmental threat due to its high content of organic pollutants and heavy metals. Elevated levels of chemical oxygen demand (COD), biochemical oxygen demand (BOD), and lead (Pb) may contaminate soil and surrounding water bodies if the leachate is not properly treated. Phytoremediation using water hyacinth offers an eco-friendly and low-cost alternative for leachate treatment. This study was conducted to evaluate the effectiveness of water hyacinth in reducing COD and BOD concentrations and removing Pb from leachate. An experimental method with a batch reactor system was applied, using 30 clumps of water hyacinth in each tank and contact time variations of 7, 14, and 21 days. COD, BOD, and Pb concentrations were measured before and after treatment using standard water quality analysis methods. The results showed that the 21-day contact time produced the highest removal efficiency. COD decreased from 1551.21 mg/L to 520.32 mg/L, representing a 66.44% reduction, while BOD decreased from 576.34 mg/L to 150.62 mg/L, equivalent to a 73.88% reduction. Pb concentration also decreased from 0.92 mg/L to 0.18 mg/L, with a removal efficiency of 80.43%. These reductions are attributed not only to the physiological activity of water hyacinth but also to the interactions among hydrological conditions, root zone architecture, and rhizosphere-mediated microbial communities, which collectively facilitate biodegradation, assimilation, and bioaccumulation of pollutants. Overall, the study highlights the critical role of integrating environmental geoscience principles with phytoremediation to optimize leachate treatment. Understanding the geochemical characteristics of leachate, subsurface hydrodynamics, and plant-microbe interactions provides a scientific basis for designing sustainable, low-cost, and efficient treatment systems. The findings indicate that water hyacinth can serve as a practical and geoscience-informed solution for mitigating organic and heavy metal pollution from landfill leachate, with 21 days identified as the optimum contact time.

Abstract

Hospital wastewater treatment plays a crucial role because it directly impacts environmental quality and public health, particularly due to its potentially hazardous pollutant content. This study aimed to assess the effectiveness of the Wastewater Treatment Plant (WWTP) at Hospital X by comparing the quality of wastewater at the inlet and outlet. The method used was a quantitative descriptive approach with data collection techniques in the form of field observations, sampling, and laboratory tests. Air samples were analyzed based on physical, chemical, and microbiological parameters, namely Total Suspended Solids, pH, Biological Oxygen Demand, Chemical Oxygen Demand, ammonia, and total coliform. The analysis results showed a decrease in concentrations of most parameters after the treatment process, with efficiencies of 66.59% for Total Suspended Solids, 88.89% for Biological Oxygen Demand, and 91.27% for Chemical Oxygen Demand. The pH value was still within the quality standards. However, the ammonia concentration increased, although still below the permissible limit. Overall, the WWTP performance was considered effective in reducing the pollutant load, and the treated wastewater met applicable standards, although optimization of the nitrification process was required.

Abstract

The increasing volume of waste in Bojonegoro Regency has led to increased leachate production at the Final Processing Site, particularly the Banjarsari Landfill, which has the potential to cause environmental pollution. This study aims to analyze leachate distribution patterns and evaluate leachate quality around the Banjarsari Landfill. The research method includes direct measurements at 13 observation points to determine the acidity (pH), temperature, and soil moisture values. Leachate samples were also taken at the inlet and outlet of the treatment plant for analysis based on the parameters of pH, BOD, COD, TSS, total nitrogen, and the heavy metals cadmium (Cd) and mercury (Hg). The results showed that the soil pH ranged from 4.5–7.0 and the soil temperature between 28–37°C, with variations at each observation point. Some locations showed more acidic conditions suspected to be influenced by leachate seepage. Leachate distribution was identified as uneven and influenced by distance from the source, soil moisture, and groundwater flow direction. The results of quality tests showed a decrease in pollutant concentration after treatment, so the leachate treatment system is considered effective and meets applicable quality standards.
