Abstract

The irrigation water requirement must be balanced with the available water to support plant growth and increase agricultural production. Therefore, information regarding the amount of water needed and its availability is essential for irrigation activities. This research analyzed the water flow availability at the Garum DAM intake using the Weibull method, irrigation water requirement in the Garum and Jatisari irrigation areas using Cropwat 8.0 software (Penman-Monteith Method), and water balance between water availability and the irrigation water requirement of the Garum and Jatisari irrigation areas using a comparative method. The data used included intake flow, climate, rainfall, soil, and plant data. The results of this study show that the water flow available at the Garum DAM intake tends to be high in the rainy season and will tend to be lower in the dry season. Furthermore, the water requirement in the Garum and Jatisari irrigation areas tends to be high during the dry season and decreases during the rainy season. The water balance shows that the water available at the Garum DAM intake cannot fulfill the irrigation water requirement of the Garum and Jatisari irrigation areas. This is because of the lack of a water deficit in certain months.

Abstract

Understanding the characteristics of domestic wastewater is crucial for designing effective wastewater treatment facilities that comply with regulatory standards. This study examined key parameters, including pH, BOD, COD, TSS, oil and grease, ammonia nitrogen, and total coliform, outlined by Indonesia’s Ministry of Environment and Forestry (MoEF) under their regulation. Samples were collected monthly over a 12-month period from three types of facilities: shopping centers, office buildings, and hospitals. The results indicated significant variability among the sites. The shopping center recorded the highest concentrations of BOD and TSS, with values of 231 mg/L and 366 mg/L, respectively, while the hospital showed elevated COD levels, reaching 725 mg/L. Its processing requires a wastewater treatment plant that aims to reduce various parameters that exceed the threshold based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number P.68 /Menlhk/Setjen/Kum I/8/2016 on Domestic Waste Quality Standards. These findings underscore the need for tailored wastewater treatment approaches based on facility type to mitigate environmental impacts and maintain water quality standards.

Abstract

Water pollution, particularly from textile industry waste, has become an increasingly significant environmental issue. Textile waste, especially synthetic dyes, contributes substantially to water pollution because of its complex structure and low biodegradability. Dyes such as Remazol Brilliant Red and Remazol Turquoise Blue, which are commonly used in the textile industry, are stable, toxic, and difficult to degrade biologically. One promising approach to address this issue is photocatalysis using photocatalysts such as CuO and CeO₂, which possess high degradation capabilities for organic contaminants. This study explored the effectiveness of CuO-CeO₂-based photocatalysts in degrading Remazol Turquoise Blue and Remazol Brilliant Red dyes. Photocatalysts were synthesized with varying CuO-CeO₂ concentrations, and degradation tests were conducted using UV light to observe dye degradation. The results show that the CuO-CeO₂ photocatalysts at a concentration of 25% achieved the highest degradation efficiency, with nearly 41.5% removal of Remazol Turquoise Blue and 26.1% removal of Remazol Brilliant Red after 120 min. Increasing the photocatalyst concentration increases the number of active sites, accelerating the degradation process. However, there is a limitation at very high concentrations because of the potential for catalyst particle agglomeration.

Abstract

Non-revenue water (NRW) is a significant issue for water supply in Indonesia, with a national NRW rate of 33.7% in 2022 and even higher at PT Air Minum Giri Menang (PT AMGM) at 36.21%. Although District Metered Areas (DMA) were implemented in 2018, their effectiveness has been limited due to poor monitoring. This study evaluates the current DMA conditions by creating a water balance and using EPANET 2.2 software for analysis, along with formulating optimization strategies through technical, financial, and institutional assessments. The research identifies fifteen DMAs, with five being well-established. Two DMAs were chosen for optimization. Simulations showed that many pipes in these DMAs did not meet flow speed standards. Water pressure in DMA Graha Permata Kota was fully satisfied at 100%, while DMA Elit Kota Mataram achieved 84.5%. The study noted a significant NRW reduction by an average of 27.26% in the selected DMAs. The total repair cost was Rp 14,725,300, leading to additional annual revenue of Rp 128,747,424 and a positive feasibility analysis. Institutional performance was rated as "good," but an increase of 14 field staff for water loss control is needed.

Abstract

Environmental pollution from wastewater and soil contamination remains a critical global concern, with current treatment methods often facing limitations in scalability, cost, or environmental safety. Biochar, a carbon-rich material derived from biomass pyrolysis, has emerged as a sustainable adsorbent for heavy metals and organic pollutants. While its use in environmental remediation is well-established, the fate and reuse of spent biochar have received limited attention. This comprehensive review explores the untapped potential of used biochar, particularly for the removal of hexavalent chromium (Cr(VI)) from wastewater and its role in enhancing soil fertility. We critically analyze current practices, mechanisms of Cr(VI) removal using spent biochar, regeneration techniques, and field applications, while highlighting circular economy frameworks that promote resource efficiency. The study integrates empirical evidence from recent case studies and offers policy recommendations to support large-scale implementation. This work is the first to provide an integrative review of the reuse of spent biochar with a dual focus on wastewater treatment and soil enhancement, underpinned by a circular economy perspective. It addresses critical research gaps by evaluating regeneration techniques, post-use functionality, and practical field applications, thereby positioning spent biochar as a viable, low-cost, and eco-friendly alternative in environmental management systems.

Abstract

Biofilters are a type of attached growth biological treatment that is considered effective among other biological treatments because of their more affordable energy operating costs, easy maintenance and operational requirements, and low environmental impact. However, there is still minimal research related to the use of local microorganisms for biological wastewater treatment. Therefore, this study aims to improve biological wastewater treatment in the cracker industry in Indramayu using local microorganisms equipped with a biofilter that utilizes natural andesite stone as a medium for microorganism growth. The best reduction in BOD anaerobically reached 79.45% and 58.91% aerobically, obtained at a flow rate of 11.11 ml/minute on the 53rd and 45th days. The increase in the BOD/COD effluent ratio from 0.22 to 0.47 during treatment indicated a decrease in biologically degradable compounds and an increase in the effectiveness of local microorganisms in reducing organic matter. Therefore, in this study, we successfully designed a biofiltration system derived from local microorganisms to effectively remove pollutants from wastewater, particularly in the cracker industry.

Abstract

Piping induced by seepage poses a significant risk to the stability of Randugunting Dam, located in Blora Regency, Central Java. This study aims to assess the geological and engineering geological conditions of the study area and to analyze the behavior of pore water pressure and seepage during the impounding stage. The methodology includes geological and engineering geological mapping, as well as field monitoring using instruments such as vibrating wire piezometers, v-notch, and observation wells. These field results were then compared with Finite Element Method (FEM) analysis conducted in GeoStudio SEEP/W 2018. The pore water pressure values derived from FEM analysis were generally higher than the actual values recorded by the piezometers. Groundwater levels observed in the wells showed a strong correlation with rainfall intensity. The actual seepage discharge measured at the v-notch was 0.000118 m3/sec, whereas the FEM analysis yielded a significantly higher discharge of 0.01271 m3/sec. Despite this, the measured discharge remains within safe limits, being less than 0.016 m³/s (2% of inflow) and below 0.14 l/min/m. Nevertheless, the higher discharge indicated by FEM analysis suggests a potential risk of piping that warrants attention.

Abstract

Waste management remains a critical challenge in Indonesia, particularly in urban areas. Bioconversion using Black Soldier Fly Larvae (BSFL) presents a sustainable solution for transforming organic waste into high-value biomass rich in protein and fat. The objective of this study was to investigate the potential utilization of organic waste from markets, bakeries, and rejected products from the food and beverage (F&B) industry (specifically creamer and milk), as BSFL substrates, while mapping the existing bioconversion sites. Data was collected through interviews, observations, and field measurements. Primary data included location details, technical specifications, implementation constraints, and BSFL bioconversion sites. Waste composition was analyzed via Loud Count Analysis during a 4-day sampling period. This research was conducted in Surabaya City and its surroundings. The results indicate that market waste mostly consists of dark green vegetables (26.5%), other vegetables (64.1%), and year-round fruits (53.9%). Furthermore, the daily average rejected bread is 2.6-2.7 kg. Rejected foods and beverages include creamers, liquids, and sweetened condensed milk. The facility processes 16.16 tons/day of substrate potential, producing 44.61 tons fresh larvae and 53.85 tons frass, with profits of IDR 58.1-969.6 million. The findings demonstrate significant potential for utilizing local organic waste as BSFL substrates in the study area.

Abstract

A significant amount of global greenhouse gas (GHG) emissions comes from Indonesia, largely driven by deforestation and land degradation. As a developing nation, it is also dealing with the growing pressures of urban expansion. This study assesses the distribution of carbon stock in Parepare City, South Sulawesi, Indonesia. Notably, Parepare City has not yet experienced extensive land-use transformations, retaining substantial carbon stock, which positions it as a proactive case study for preventing future carbon loss amidst ongoing urbanization. Using the InVEST Carbon Storage and Sequestration model with SPOT 7 satellite imagery (2016) and global carbon density data, the research quantifies carbon storage across various land use/land cover (LULC) types. Analysis reveals natural ecosystems, particularly mixed forests and fields, hold the highest carbon storage potential. The total estimated carbon stock in Parepare City is 1,456,909.41 Mg C. These findings emphasize the urgent need for climate-responsive land management, including forest conservation, and urban greening, to enhance local carbon sinks and support Indonesia's climate change mitigation goals. This assessment provides crucial insights for urban planners and policymakers to balance growth with ecosystem conservation for a susta00inable future.

Abstract

Landslides are among the most unpredictable and destructive sediment-related disasters, especially in mountainous regions with complex terrain and limited field accessibility. In 2004, a catastrophic landslide from the Mount Bawakaraeng Caldera delivered more than 100 million cubic meters (MCM) of sediment into the Bili-Bili Reservoir, filling its dead storage and threatening its long-term functionality. his study uses Sentinel-1A satellite imagery and Differential Interferometric Synthetic Aperture Radar (DInSAR) to perform a rapid, spatially driven assessment of landslide hazards in the Bili-Bili Reservoir Catchment Area. The results reveal surface deformation of up to ±1.55 meters, concentrated in upstream zones. High-risk areas span 71.00 km², with an estimated mobilizable volume of 110.04 MCM and a potential sediment yield of 27.14 MCM per year, nearly equal to the reservoir’s dead storage. To mitigate this threat, the study proposes an integrated mitigation framework. Structural interventions include rehabilitating existing sediment control systems and constructing new sabo dams. Non-structural strategies such as slope revegetation and bioengineering are also recommended. This study demonstrates how remote sensing can identify subtle ground deformation and provides actionable insights for safeguarding critical water infrastructure in sediment-prone tropical watersheds.
