Abstract

Pencemaran air sungai merupakan salah satu permasalahanlingkungan di Kabupaten Sleman. Salah satu faktor yang berhubungan dengan pencemaran air sungai adalah penggunaan lahan. Penelitian ini dilakukan untuk mengukur tingkat hubungan antara penggunaan lahan dan kualitas air sungai padai skala DAS dan sempadan sungai. Ada tujuh parameter kualits air yang digunakan, yaitu TSS, DO, BOD, COD, TP, fecal coliform, total coliform, dan indeks pencemaran. Data kualiats air sungai diambil dari data yang tersedia dalam laporan pemerintah. Data penggunaan lahan didapat dari MODIS Land Cover Type Product yang diklasifikasikan menjadi empat: lahan pertanian, hutan, padang rumput, dan perkotaan. Analisis korelasi Spearman Rank digunakan untk menemukan hubungan antara penggunaan lahan dan kualitas air sungai. Ada 60 titik sampek dalam penelitian ini. Dari penelitian ini ditemykan bahwa penggunaan lahan pertanian dan perkotaan memiliki hubungan dengan penurunan kualitas air sungai. Sebaliknya, penggunaan lahan padang rumpur dan hutan memiliki hubungan yang positif dengan kualitas air yang baik. Dari penelitian ini, untuk menjaga atau meningkatkan kualitas air sungai, pengembangan area hijau yang sekaligus berfungsi sebagai ruang terbuka publik sangat diperlukan utamanya di daerah perkotaan.

Abstract

Introduction: Tegal Panggung is a high population density sub-district of 26,326 inhabitants/km2. Most residents utilize wells to meet their water demands, but fecal coliform bacteria were found in several wells at Tegal Panggung. This type of contamination source is typically from on-site wastewater treatments. However, wastewater from Tegal Panggung is treated at a centralized wastewater treatment plant. This study is aimed at identifying the factors leading to the presence of fecal coliform bacteria in Tegal Panggung. Methods: Factors reviewed in this study were the amount of waste, drainage, cattle pens, toilets, types of wells, and building density. Statistical methods and GIS were applied to determine the influence of the factors on the presence of fecal coliform and to map its distribution along with potential sources of pollution. The number of wells tested was 32, with a research period from September to October 2021. The statistical methods used are the Kolmogorov-Smirnov Normality Test, the Spearman Correlation Test, and the spatial analysis method, which was carried out using QGIS. The statistical tests were conducted to determine the correlation value between fecal coliform and pollutant. Results and Discussion: The study showed that only 40.62% met the standard requirements when there should be no fecal coliform contents in well water. Conclusion: Based on the Spearman Correlation Test, it can be deduced that the factors affecting the presence of fecal coliform within 10 meters radius are garbage and of 30 meters radius are toilets and building density.

Abstract

The need for clean water during the pandemic is significantly increasing due to high public awareness of adopting a clean and healthy lifestyle (PHBS), necessitating more water treatment. Conventional methods are used for water treatment, including coagulation-flocculation system, rapid sand filter, and disinfection. However, these methods have limitations such as reduced capacity and sand filter efficiency, leading to increased backwash costs due to the need for sand replacement caused by particle stratification. In response to these challenges, an innovative method to water treatment is the use of concrete sand filter (CSF). Previous studies predominantly focused on downflow filtration, but there has been limited analysis of horizontal flow. Therefore, this study aimed to assess filtration and backwash effectiveness of CSF with horizontal flow, specifically focusing on the capacity performance in treating water with varying levels of turbidity. Filtration experiment was carried out using simulated water at turbidity of 125 NTU based on the Mataram Channel Turbidity with variations of 0.2, 0.5, 1.0, 5.0, and 10.0 m hour-1, as well as backwash at flow rate of 40.91 m hour-1 for 3 minutes. The variables measured during filtration process included head losses and turbidity at the inlet and outlet of CSF. The results showed that the capacity performance during filtration process was directly proportional to flow rate. Meanwhile, the effectiveness of concrete filter was inversely proportional to flow rate. At initial turbidity <617 NTU, the 3 minutes backwash process obtained lower final turbidity compared to the raw water used, which was 5.19 NTU. Meanwhile, at turbidity 617 NTU, the final turbidity was still high, reaching approximately 14.6–26.4 NTU.

Abstract

Some citizens of the Kalurahan Banaran Kabupaten Kulon Progo everyday use water that has an iron content (Fe) of 8.8 mg/L and a turbidity of 120 NTU, which is above the limit set by the Minister of Health's Regulation RI Number: 2 Tahun 2023 on the Quality Requirements of Drinking Water. To solve this problem, research has been conducted to reduce Fe and turbidity by using porous concrete filters. Three models of porous concrete A (porousity 0.42), B (porousity 0.44), and C (porousity 0.46), were used to filter water samples using two aerator diffusers at speeds of 3 L/h and 6 L/hour on each porous concrete filter. The results of the study showed that at an aeration rate of 3 L/hour, there had been a successive decrease in turbidity and Fe from 14.9 NTU to 1.38 NTU and 1.64 mg/L to 0.14 mg/L (filter A); 80 NTU to 0.5 NTU and 6.55 mg/L to 0.02 mg/L (filter B); 80 NTU to 0.1 NTU and 6.5 mg/L to 0 mg/L (filter C). For an aeration rate of 6 L/hour, there had been a successive decrease in turbidity and Fe from 80 NTU to 0.82 NTU and 6.55 mg/L to 0.05 mg/L (filter A); 89.8 NTU to 0.28 NTU, and 7.8 mg/L to 0.01 mg/L (filter B); 80 NTU to 0.28 NTU and 6,55 mg/L to 0 mg /L (filter C). The results show that the porous concrete filter can be considered an alternative to drinking water treatment in the Kalurahan Banaran Kabupaten Kulon Progo.

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

Biogas is one of the alternative renewable energy sources that are useful in our lives. Kecamatan Jabung located in Malang, has the potential to produce and develop this kind of energy resources. However, biogas contains many impurities such as H2O, CO2, and H2S that could have a negative impact. Therefore, it is necessary to purify the biogas by making an installation column. The purification process is carried out by utilizing solid adsorbents including zeolite and activated charcoal. However, because solid adsorbents have a certain capacity, an integrated indicator to determine the adsorbent capacity will be needed. The existence of this indicator will be helpful for the public to monitor whether the adsorbent needs to be regenerated or replaced. According to the trial result, we may conclude that silica gel is a promising indicator to determine H2O and H2S adsorption capacity. Meanwhile, lime water can also be used as an indicator of the adsorption capacity of CO2.

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.
