Effectiveness of Screening Models in Improving the Quality of Cenrana River Water as a Drinking Water
Summary
This study assessed the water quality of the Cenrana River in Indonesia as a potential drinking water source and evaluated the effectiveness of different screening and treatment models, identifying key contaminants and recommending suitable treatment approaches for the community.
The objective of this study is to assess the quality of the Cenrana River water as a potential drinking water source for a community in the Cenrana watershed Wajo, as well as to evaluate the effectiveness of a basic water purification system in improving its condition. Cenrana River is located in the Maros Regency and Bone Regency, South Sulawesi Province, Indonesia. The study was conducted at the Laboratory of Material Testing, Faculty of Engineering Universitas Negeri Makassar, and the Makassar Health Laboratory Center. Water samples are taken in the Walanae River located in Bone Regency and tested in the abovementioned laboratory. This type of research is experimental, which involves assembling a simple clarification tool in the material testing laboratory, and then raw water is purified with the device. Water samples, both raw water and purified water, are tested at the Makassar Health Laboratory Center. The data analysis used is qualitative descriptive, which compares the results of laboratory tests of raw water that have not been clarified and the results of laboratory tests of water that have been purified with the parameters of clean water standard criteria based on the regulation by the Ministry of Health of the Republic of Indonesia. The results showed that although the water had been cleaned through two filters, several parameters tended to increase from the previous year's test results with one filter, such as the No2 content from 0.017 to 0.034, No3 from 0.01 to 0.39, dissolved solids from 152 to 156, Fe from 0.01 to 0.17, Mn from 0.01 to 0.15, SO4 from 14.39 to 15, 54, and Ammonia from 0.05 to 0.29 even though it still meets the standards of the Ministry of Health of the Republic of Indonesia. In addition, the raw water coliform content also increased from an average of 6,600/100 ml in 2016 to 20,050/100 ml in 2019. This means that there is a tendency for Cenrana River water pollution may increase every year.

Performance of Conventional Drinking Water Treatment Plants in Removing Microplastics in East Java, Indonesia
This Indonesian study tested two conventional drinking water treatment plants in East Java for their ability to remove microplastics, finding that full multi-stage treatment achieved significant reduction but did not eliminate all particles. The results show that conventional water treatment partially protects consumers but may not prevent all microplastic ingestion through drinking water.
Microplastic Contamination in Drinking Water Treatment Systems: A Case Study of Bedadung River Jember
Researchers traced microplastic contamination through the Bedadung River water treatment chain in Indonesia, from intake to consumer taps, at seven sampling points. MPs were present throughout the system, with concentrations declining through treatment stages but not reaching zero, indicating residual MP exposure in treated drinking water.
Assessment of Bango River Water Quality on Different Land Uses
Researchers assessed water quality in the Bango River in Indonesia across different land uses, finding that agricultural, residential, and industrial activities each contributed distinct pollution patterns affecting physicochemical parameters and overall river health.
Water Pollution of Some Major Riversin Indonesia: The Status, Institution, Regulation,and Recommendation for Its Mitigation
This review examines water pollution in four major Indonesian rivers, analyzing the status of contamination, institutional frameworks, and regulatory responses. Researchers found that rapid population growth and industrialization have left only 73% of Indonesians with access to safe water, with heavy metals, organic pollutants, and plastic waste among the key contaminants. The study recommends integrated approaches combining stronger enforcement, community engagement, and improved waste management to mitigate river pollution.
Water pollution and sanitation in Indonesia: a review on water quality, health and environmental impacts, management, and future challenges
Many water sources across Indonesia are contaminated with heavy metals, microplastics, pesticides, and endocrine-disrupting chemicals, and existing treatment plants fail to fully remove them. Inadequate sanitation has been linked to maternal health complications, childhood stunting, and increased diarrheal disease incidence.
