Abstract

Wastewater refers to water generated from human or business activities and is categorized into domestic and non-domestic wastewater. Domestic wastewater originates from residential or business activities and is often discharged directly into water bodies without proper treatment, even if it does not meet established quality standards. Wastewater quality standards define acceptable pollutant levels before discharge into water or soil media. Untreated wastewater can pollute the environment, causing water discoloration, foul odors, fish mortality, and the spread of disease. This study examines the centralized domestic wastewater treatment system at the National Housing City (Perumnas) in Cirebon. The research focuses on analyzing the treatment process, evaluating system efficiency, and comparing results to applicable standards and regulations. Data for this thesis were obtained from the Perumnas Wastewater Treatment Plant (IPAL) of Cirebon City, including both primary and secondary data. The main issues studied involve pump capacity and available land for plant expansion. The Perumnas IPAL is designed to treat domestic wastewater with a capacity of 6,000 SL. Assuming one SL serves four people and daily water consumption is 180 L/person/day, the estimated wastewater flow is 3,456 m³/day. The wastewater is processed in three types of ponds: an anaerobic pond (1 unit), a facultative pond (1 unit), and two maturation ponds, with the treated output intended for PDAM water use.

Abstract

The ongoing development of infrastructure technology, particularly in constructing buildings, plays a vital role in national progress. Concrete, a widely used construction material, is crucial for civil works and overall development.In this study using an innovation in concrete mixes by utilizing waste that can damage the environment, such as fly ash as a cement additive, plastic waste as a coarse aggregate additive, natural stone waste as a fine aggregate additive. The primary objectives of this study are to assess the impact of waste addition on concrete production, establish optimal and minimal waste variations affecting concrete compressive strength, and evaluate the performance of waste mixtures in comparison to normal concrete. Various waste percentages were integrated into the concrete mix: fly ash (5%, 10%, 15%, 20%, 25%, 30%), plastic waste (2%), and natural stone waste (40%). Test specimens were cube-shaped, measuring 15x15x15 cm. Concrete curing took place over 7, 14, 21, and 28 days, with subsequent compressive strength testing. . From the analysis results show a significant correlation between the proportion of added ingredients in the concrete mixture tends to increase the compressive strength of concrete at a certain limit, obtained the optimum value at 20% variation with a compressive strength of 328.0036 kg/cm2 and the minimum value at 30% variation with a compressive strength of 276.3318 kg/cm2 at the age of 28 days, the use of waste in concrete mixes is very good and can be an alternative in making concrete with environmentally friendly properties.
