Abstract

In recent years, Universitas Kebangsaan Republik Indonesia (UKRI) has experienced rapid growth in the education sector, facilities, as well as an increasing number of students and staff. Along with this development, the volume of wastewater produced has also seen  significant increase. If not managed efficiently, this wastewater can pose a threat to the surrounding environmental quality and potentially become a source of public health issues. Therefore, efforts to improve sanitation are required, such as the installation planning of domestic wastewater treatment facilities at the UKRI campus. Wastewater treatment through the aerobic biofilter method is one system that employs biological processes, consisting of media that serve as a habitat for submerged microorganisms, supplemented with an aeration system. The chosen domestic wastewater treatment installation in the UKRI campus is the aerobic biofilter. The planning for the selection of this installation is based on land requirements, construction, operation, maintenance, investment costs, and efficiency. The calculated wastewater flow rate is 57.6 m3/day. The aerobic biofilter produces effluent with concentrations of temperature 28 ºC; pH 7.5; TSS 18.69 mg/L; COD 73.64 mg/L; BOD 37.66 mg/L. The construction of the aerobic biofilter consists of fiber and concrete materials with dimensions of 5 m in length, 0.6 m in width, and 1.5 m in height.

Abstract

Kinetic models are widely used to predict the performance of biological treatment systems. The facultative ponds are applied as a biological treatment for domestic wastewater in the Wastewater Treatment Plant (WWTP) located in Bojongsoang, Bandung Regency, West Java. This study aims to evaluate the suitability of several kinetic models for the chemical oxygen demand (COD) removal process that occurs in facultative ponds in WWTP Bojongsoang. The best kinetic model will provide a more accurate predictions of COD effluent concentrations in facultative ponds. Data series of COD influent and effluent concentration were collected from field data of water quality monitoring monthly from years 2019 to 2022. The kinetic models used in this study were the first-order kinetic model combined plug flow pattern, the first-order kinetic model with continuous stirred tanked reactor flow pattern, the plug flow k-C* model, and the Stover-Kincannon model. Model accuracy was evaluated using statistical methods by calculating the mean average percentage error (MAPE) to compare model data with measured observation data. The COD effluent prediction showed that the Plug Flow k-C* model had the smallest MAPE for both facultative ponds, namely 28.3% for facultative pond 1A and 30.2% for facultative pond 2A. Kinetic rate values for both facultative ponds using plug flow k-C* model respectively, 0.1818 m/day for F1A and 0.1750 m/day for F2A.

Abstract

Plastic waste is a significant environmental issue, particularly due to its slow decomposition and incresing accumulation. One solution to mitigate plastic waste is the Ecobrick method., where non-organic plastic is compacted into plastic bottles to create durable building materials. This study focuses on the socialization and assistance program for plastic waste recycling using Ecobrick method at SDN Kawungsari, Bandung Regency. The program aims to raise awareness among students and the community about the importance of waste separation and the potential of Ecobricks, along with follow-up assistance to ensure continuous practice. Surveys and observations were conducted before and after the program to measure changes in knowledge, attitudes, and participation levels regarding plastic waste recycling. The result showed a significant increase in awareness and active involvement from students and teachers in the creation of Ecobrick. This initiative demonstrates the potential of educational interventions to foster sustainable waste management practices in local communities.
