Abstract

Hospital activities generate by-products from the treatment of liquid waste, namely sludge that settles in sedimentation tanks. The sludge produced thus far has been transported by a third party in collaboration with the hospital. This study was conducted to utilize hospital wastewater treatment plant (WWTP) sludge with the aim of determining the moisture content, carbon (C) content, nitrogen (N) content, and C/N ratio in the raw WWTP sludge before and after composting compared to SNI 19-7030-2004 standards. Additionally, the study aimed to identify the average differences in each variation of WWTP sludge and rice husk composition. This research employed an experimental method. The composting process was conducted aerobically with the following variations: 95% WWTP sludge:5% rice husk (A1), 85% WWTP sludge:15% rice husk (A2), 75% WWTP sludge:25% rice husk (A3), and 65% WWTP sludge:35% rice husk (A4), with the addition of EM4 activator 55 ml + 90 ml sugar solution diluted to 300 ml. The preliminary test results for the WWTP sludge showed a moisture content of 68.76%, C content of 28.00%, N content of 14.32%, and C/N ratio of 1.95. From the results of the ANOVA statistical test and Post Hoc Duncan test, it was found that the average variation in WWTP sludge: rice husk composition had a significant difference, with the ideal composition being variation A1 (95% WWTP sludge:5% rice husk).

Abstract

Aim: This study was aimed to analyze the potential of water sources in the Ciberang River to support drinking water supply system of Banten Province. Methodology and results: The method use to analyze the potential of Ciberang river is a hydrological statistical analysis. The results of the hydrological statistical analysis show that the water resources of the Ciberang River are not sufficient to meet domestic and industrial water needs in Banten Province. Domestic and industrial water demand in Banten Province in 2025 is estimated at 14.64 m3/s and 10.46 m3/s, respectively, while the mainstay discharge with the return period of 10 and 20 year for all durations does not meet these water needs. The mainstay discharge of the Ciberang River with a 10-year return period of 1, 2, 7, 15 and 30 day respectively was 0.08 m3/s, 0.1 m3/s, 0.19 m3/s, 0.36 m3/s, and 0.87 m3/s. The mainstays of the 20-year return period of 1,2,7,15 and 30 day respectively are 0.04 m3/s, 0.06 m3/s, 0.11 m3/s, 0.23 m3/s and 0.59 m3/s. Conclusion, significance, and impact study: Based on this, it is necessary to conserve water resources to increase the main flow of the Ciberang River. One of the strategic policies to increase the river's mainstay discharge is constructing the reservoir.
