Abstract

Decentralized water treatment system is water treatment carried out by the community on a household-scale. One of the technologies that have been developed to gain freshwater is the pervious concrete filter (PCF). This study aims to provide the researchers with an understanding of the pervious concrete filter as a potential filter technology in water treatment. The method used is a literature review from several papers and reports related to pervious concrete from past to present. PCF is a filter made from a mixture of aggregate, cement, and water with a specific ratio. PCF has enough water and air permeability due to interconnected macro pores. Some properties such as porosity, permeability, and pores size determine the ability of PCF to remove the contaminants in the water. These properties were controlled mostly by the aggregate size, aggregate-cement ratio, water-cement ratio, etc. According to its characteristic, the PCF shows a prospect to be used as water filter mainly in a decentralized water treatment system. Besides, the understanding of PCF is a basis to develop a pervious mortar filter that slightly different in the aggregate sizes used in this composite.

Abstract

Sand filter is a widely used water treatment technology due to its operational simplicity. The drawbacks of sand filter operation are long backwash times and particle stratification, leading to high energy and sand replacement costs. The concrete sand filter (CSF) was created by mixing sand with cement paste as a binding agent. CSF establishes its water production capacity based on its effective porosity and permeability, which are influenced by the shape of the sand. CSF may have more spherical particles because the cement paste covers the sand. Previous studies have investigated the influence of the shape and size of aggregates on the porosity and permeability of pervious concrete. This study investigates the effective porosity and permeability of CSF using various sand shapes and cement-to-sand (c:s) ratios, as well as changes in the shape of the sand grains used to build the CSF due to mixing with cement paste. The sand types are characterized by their circle ratio sphericity; the c:s ratios tested are 0, 1:6.4, and 1:8.6. All specimens are 10.9 cm in diameter and 20 cm in height. The water displacement method was employed to measure the effective porosity, while the constant head method was used to determine the permeability. The results indicate that when the circle ratio sphericity of the sand used to build the filter increases, the effective porosity and permeability of filters decrease for all values of c:s. Specimens with high cement content have lower effective porosity and permeability and show a strong linear relationship (R² = 0.9555 at c:s = 1:6.4).

Abstract

In Indonesia, household-scale infiltration wells serve dual functions: managing rainwater and acting as secondary treatment systems for domestic wastewater from septic tanks. These roles require distinct designs, particularly in the arrangement and thickness of filter media. According to Indonesian technical standards (SNI – Standar Nasional Indonesia), wells designed for septic tanks use thicker, multi-layered filters that occupy most of the well's volume, while rainwater wells typically feature only a thin filter at the base. This difference reflects the higher pollutant levels in septic tank effluent compared to rainwater. Direct interviews with housing contractors in Sleman Regency, involving 836 household samples, revealed that all households repurposed rainwater infiltration well designs for managing domestic wastewater. Such practices deviate from intended design standards, raising concerns about the effectiveness of the filtration systems in these wells for contaminant removal and their potential contribution to groundwater pollution. The study further examined correlations between population density, soil characteristics, and the design and usage patterns of infiltration wells. In densely populated areas, more complex systems are often employed to manage wastewater and rainwater efficiently in limited spaces. In contrast, simpler systems are more common in less populated areas. Additionally, regions with clay-rich soils require larger wells to accommodate slower infiltration rates, while areas with sandy soils need smaller wells due to higher infiltration rates. These findings emphasize the importance of aligning infiltration well designs with both their intended purposes and local environmental conditions. Properly designed systems that manage wastewater and rainwater separately can reduce the risk of groundwater contamination, promoting more sustainable water management practices.

Abstract

The durability of pervious concrete is threatened by the phenomena of leaching (chemical dissolution) and abrasion (mechanical wear). This systematic literature review analyzes studies from Scopus (2019–2024), utilizing keywords such as “pervious concrete” or “porous concrete”, “leaching”, and “abrasion”. Articles were selected based on open access, peer-review status, and relevance to experimental/theoretical data. Leaching, primarily driven by the dissolution of calcium from portlandite and C-S-H phases, weakens the cement matrix and increases porosity. Meanwhile, abrasion is physical wear resulting from mechanical forces that erode the cement paste and lead to aggregate dislodgement. Critically, leaching and abrasion interact synergistically in a self-reinforcing degradation cycle: leaching weakens the matrix, making it more susceptible to abrasion, while abrasion exposes fresh material, accelerating further leaching. Although material optimization (e.g., angular aggregates and silica fume additives) and controlled carbonation curing can mitigate degradation, significant research gaps persist. Notably, there is a lack of systematic investigation to optimize cement-aggregate ratios for simultaneous leaching and abrasion resistance, as well as a scarcity of standardized coupled degradation test protocols. To address this gap, a systematic investigation is needed to optimize the sand-to-cement ratio in concrete filters, balancing durability (including resistance to fluid friction during backwashing) with sustained filtration capacity. This is crucial for developing pervious concrete as a sustainable and durable urban solution.

Abstract

Providing access to sanitation is one of the global and national commitments in order to improve people's welfare. Inadequate sanitation results in a number of health risks such as diarrhea, malnutrition, stunted growth, and several other health problems. The purpose of this study was to identify the accessibility of proper sanitation for the people of Tapin Regency. The scope of this study was the condition of sanitation facilities and infrastructure available in homes in Tapin District. The methods used in this research were interviews, field observations, and documentation. Data sources were determined using purposive sampling techniques. Based on the findings in the field, some people still practice open defecation even though they have a toilet at home. A more economically viable alternative for the community for a sustainable sanitation system is to concentrate on safe fecal disposal for those using latrines rather than building a new large-scale wastewater system. There are 5 indicators studied to determine the level of access to community sanitation, namely the availability of handwashing with soap and clean water facilities, access to proper sanitation, open defecation behavior, access to household wastewater management systems, and access to septage management systems. This study highlights the importance of using comprehensive sanitation indicators beyond basic latrine access, especially in rural areas where data is limited, local governments should prioritize investment in fecal sludge treatment infrastructure and strengthen community engagement in sanitation behavior change programs.

Abstract

Penggunaan pupuk NPK pada lahan pertanian secara berlebihan mengakibatkan banyak pupuk tidak terserap sehingga terbawa masuk ke perairan oleh limpasan air permukaan saat hujan dan menyebabkan eutrofikasi. Unsur hara anorganik Nitrogen (N) dan Fosfor (P) menjadi nutrisi bagi alga sehingga menyebabkan tumbuhnya alga yang berlebihan pada perairan atau biasa disebut algae bloom. Penelitian ini bertujuan untuk mengkaji seberapa besar pengaruh jenis dan tinggi lapisan media pada non-vegetated swale dalam menyaring parameter Nitrogen (N) dan Fosfor (P) yang berasal dari larutan pupuk NPK komersial. Metode yang diterapkan adalah dengan menyiramkan aliran air larutan pupuk NPK melalui non-vegetated swale dengan dua ketebalan lapisan yang berbeda. Konsentrasi masuk larutan NPK yaitu 123,77-124,77 mg/l fosfat, 16,54-16,72 mg/l amoniak serta kandungan nitrat dan nitrit yang kecil. Aliran air larutan pupuk NPK sebelum dan sesudah melalui non-vegetated swale diambil sampelnya yang kemudian diuji dengan alat spektrofotometer untuk mengetahui perbedaan kandungan fosfat, nitrat, nitrit dan amonianya. Hasil penelitian menunjukkan bahwa kedua non-vegetated swale memiliki kemampuan menyaring konsentrasi fosfat pada larutan air pupuk NPK yang sangat baik, keduanya mampu mengurangi konsentrasi fosfat hingga 120 mg/l. Hasil pengukuran nitrat dan nitrit menunjukkan kenaikan sekitar 5 mg/l, sedangkan kandungan amoniak turun sekitar 16 mg/l. Hal ini menunjukkan terjadinya proses nitrifikasi dan menunjukkan bahwa kedua non-vegetated swale pada penelitian ini memiliki kemampuan penyaringan N yang belum optimal.
