Abstract

This public educational facility was initiated by a foundation X. This foundation produces domestic wastewater from educational activities, toilets, prayer rooms, canteens, and so on. Domestic liquid waste generated will be used for watering plants in green open spaces around the foundation. The waste water discharge before being treated at WWTP is 17.18 m3 /day and the wastewater discharge after being processed is 17.1167 m3 /day. The entire treated wastewater discharge will be used to water the garden. Wastewater contains BOD, COD, TSS, Ammonia and Total Coliform which exceeds the quality standard, so it needs to be processed before it is used for watering plants. Yayasan X already has 5 WWTP units to manage wastewater. However, it is planned that there will be a building development, so an additional unit of WWTP will be carried out in the building development area so that an evaluation is carried out on the processing capability and the watering method used. The results of the processing will be used to water plants at Foundation X with an area of 1,339.20 m2 of Green Open Space. The process of watering is done two times a day in the morning and evening.

Abstract

The parameters of Fe, Mn, TDS and TOC contained in the groundwater around the coast of Gresik Regency can cause unpleasant odours when exposed to air, yellow stains on clothes and health problems for people who consume groundwater. The process of aeration and adsorption treatment can be an alternative to reduce the level of pollutants in groundwater by using crab shells and duck egg shells as adsorbents. The study was conducted by comparing 2 treatment processes, the aeration treatment process using variations in aeration time of 15 minutes, 30 minutes and 45 minutes and the adsorption treatment process using variations in the type of duck and crab eggshell adsorbents. The adsorption process also uses variations in sampling time of 20 minutes, 40 minutes and 60 minutes. In the aeration process, the maximum aeration time for removal of Fe, Mn, TDS and TOC occurs at an aeration time of 45 minutes. The percentage allowance for Fe was 91.4%. The percentage allowance for Mn was 28.6%. The percentage of TDS release was 68.2%. The percentage of TOC addition is 20.8%. In the adsorption process, the maximum samplingtime is 40 minutes. The percentage of Fe removal using duck and crab eggshell adsorbents was 97.8% and 99.2%, Mn was 75.7% and 82.7%, TDS was 84.5% and 94.1%, TOC was 74.6% and 81%. The percentage of adsorbent increases as the stirring time increases, allowing the adsorption process to run properly and optimally.

Abstract

The commitment to provide clean water and proper sanitation is one of the goals of the Sustainable Development Programs (SDGs). The government of each region needs to strive for clean water for the community. Efforts to fulfill clean water can be realized with the Water Supply System. Water Supply System sustainability indicators need to fulfill three aspects of quality, quantity, and continuity. The aim of this research is to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency which serves three villages, namely Sugio, Lebakadi, and Sekarbagus. The aspect of water quality, seen from the results of the analysis of the quality of production water, shows that it meets the quality standards as raw water for drinking water. The aspect of water quantity is calculated to meet water needs for the next 20 years. The calculations results show that the daily average debit requirement is 17 L/s and the daily maximum debit is 19 L/s, while the existing debit is 15 L/s. The aspect of water continuity is calculated from the ability to distribute water during an emergency. The calculation results show that the distribution of clean water when there is no source of electrical energy can only be carried out in a maximum of 1 hour 13 minutes 48 seconds. The conclusion obtained is that the sustainability of the ‘Sugio’ Water Supply System from the aspect of water quantity and continuity still needs to be improved.

Abstract

Climate change has become a global issue receiving serious attention worldwide. One of its principal drivers is the increase in Greenhouse Gases (GHG), particularly carbon dioxide (CO₂). Therefore, effective spatial-planning–based mitigation strategies are required. This study aims to analyze the capacity of Green Open Space (RTH) to absorb CO₂ emissions in Lamongan Subdistrict. The methods include Sentinel-2 satellite imagery analysis using the NDVI (Normalized Difference Vegetation Index) approach to determine vegetation cover, combined with carbon stock calculations based on IPCC (2006) guidelines. In addition, CO₂ emissions were inventoried from the transportation sector, household energy use (LPG), electricity, and domestic solid and liquid waste using the IPCC Tier-1 approach. The results show that the total estimated CO₂ emissions in Lamongan Subdistrict reach 17.927,46 tons/year. Meanwhile, the absorption capacity of existing RTH can absorb approximately 5.686 tCO₂/year, or 32% of total emissions, leaving residual emissions unabsorbed.

Abstract

Organic waste, particularly food waste, remains a major contributor to urban waste generation, and most of it ends up in landfills, thereby increasing the environmental burden. At the Garda Pangan Waste Management Facility, not all organic waste can be converted into maggot feed, resulting in residues characterized by a hard texture, large size, and high fiber content. This study aims to assess the potential for utilizing organic waste residues as an alternative for further processing to minimize the disposal burden on landfills. The methods used in this study include direct observation and comparative analysis of several bioconversion methods, such as eco-enzymes, vermicomposting, box composting systems, and livestock feed utilization. The results of the study indicate that the average weekly organic waste residue ranges from 360.17 to 785.12 kg, with a 35% increase from February to March 2026. Through the study, the box composting system was considered the most optimal because it can handle various types of waste with a reduction efficiency of 65–75% and is more suitable for the limited resource conditions in the field. Thus, this advanced treatment method has the potential to reduce the amount of organic waste disposed of at landfills.
