Abstract

The growing number of railway passengers in Indonesia demands improved service quality, including the provision of environmentally friendly toilet facilities. The Railway Eco-Toilet (RET) system has adopted a waste storage mechanism to reduce direct discharge into tracks or water bodies. However, the stored wastewater still requires further treatment to meet environmental quality standards. One potential alternative is eco-enzyme, a fermentation product of household organic waste that contains enzymes, organic acids, and beneficial microorganisms capable of degrading pollutants. This study aims to analyze the performance of eco-enzyme in reducing pollutants in RET wastewater and to compare it with a commercial bio-bacteria product currently applied by PT KAI. The observed parameters include Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), and Total Suspended Solids (TSS). The experiment was conducted by directly applying eco-enzyme to RET storage tanks with incubation periods of 10, 15, and 20 days. Samples were then analyzed in an accredited laboratory using standard water quality testing methods. The results on the 20th day showed that eco-enzyme reduced pollutant levels to BOD5 of 70 mg/L, COD of 206 mg/L, TDS of 1478 mg/L, and TSS of 14 mg/L. In comparison, the commercial bio-bacteria achieved BOD5 of 63 mg/L, COD of 204 mg/L, TDS of 1129 mg/L, and TSS of 53 mg/L. The analysis indicated that eco-enzyme performed better in reducing TSS, achieving compliance with environmental standards, whereas both treatments failed to lower BOD5 and COD to the required limits. These findings highlight the potential of eco-enzyme as an alternative for treating railway toilet wastewater. Its application could strengthen RET systems and be extended to domestic wastewater management such as household septic tanks.

Abstract

The availability of clean water is a basic necessity for communities, playing a crucial role in supporting health, sanitation, and quality of life. However, in many rural areas, the quality of available water still does not meet proper standards due to limited access to simple and sustainable water treatment technologies. Rancatungku Village, located in Pameungpeuk District, Bandung Regency, is one of the areas facing clean water quality issues such as turbidity, yellowish color, and unpleasant odor, despite having government-provided clean water facilities. This condition affects the comfort and health of the community in fulfilling daily domestic needs. This community service activity aims to design, build, and implement a clean water filtration system based on the backwash method as an appropriate technology that is economical, effective, and easy to maintain by the community. The implementation methods include field observation, community needs analysis, designing a dual-tank filtration system with a combination of silica sand, zeolite, manganese greensand, and activated carbon media, equipment installation, operational trials, as well as socialization and maintenance training for residents. A participatory approach was applied by directly involving the community in each stage of the activity. The results of implementation show that the backwash-based water filtration system significantly improves water quality based on visual parameters, namely reduced turbidity, elimination of yellowish color, and decreased unpleasant odor. The backwash mechanism simplifies the cleaning process of filter media without dismantling, thereby increasing operational efficiency and system lifespan. Active community participation in installation and training also supports program sustainability. Thus, the backwash-based water filtration system has the potential to serve as an appropriate technology solution that can be replicated to address clean water problems in rural areas.
