Pengelolaan dan mitigasi dampak limbah masker di Kecamatan Rungkut, Surabaya

2025-12-27T22:34:25+07:00

The utilization of masks will exert an influence on the amount of waste generated. The daily utilization of masks by Indonesians amounts to 159,214,791, contributing to a daily waste generation of 420.03 tons. The generation of mask waste necessitates effective management to ensure optimal balance. In the absence of proper management, mask waste has the potential to exert deleterious effects on the environment. The objective of this study is to ascertain the quantity, dissemination, and selection of the most efficacious management method for mask waste. The study involved the administration of questionnaires, employing a stratified random sampling method to assess the knowledge, management, and distribution of mask waste. The objective of this assessment was to formulate a suitable mask waste management method. The present study demonstrates a correlation between the variables of age, occupation, and education level on knowledge management and the distribution of mask waste. The p-value results for all variables were obtained and are less than 0.05. The methods formulated to manage mask waste generation are the democratization of information on mask waste management, and the implementation of special bins and color-coded bags or bins.

Penerapan teknik low impact development (LID) untuk optimalisasi sistem drainase (studi kasus: Kecamatan Cianjur)

2025-12-27T22:34:25+07:00

Cianjur District often experiences flooding caused by high rainfall, limited water infiltration in catchment areas, and imbalance between development rate and inadequate drainage system capacity. To address this challenge, this study proposes the application of Low Impact Development (LID) as a solution to reduce flood risk. Hydrological analysis was carried out using rainfall and runoff data to calculate the volume of water flow in existing conditions and LID application scenarios. The simulation used Storm Water Management Model (SWMM) software version 5.2 with 3 scenarios; 1) scenario without LID which produces a runoff discharge of 8,748.26 m³/s; 2) scenario using rain barrel produces 7,318.28 m³/s; and 3) scenario combination of rain barrel and retention ponds which reduce the value to be 118, 28 m³/s. The third scenario is the most effective option as a drainage management strategy in Cianjur District.

Assessing wastewater treatment performance in small island contexts: a multi-aspect evaluation of Tidung Besar Island, Indonesia

2025-12-27T23:58:38+07:00

Small islands face unique sustainability challenges in domestic wastewater management (DWM) due to limited resources, confined space, and high ecological vulnerability, yet comprehensive multi-dimensional assessments remain scarce. This study addresses this gap through a multi-aspect assessment of the DWM system on Tidung Besar Island, Indonesia, integrating technical, institutional, environmental, and social dimensions in a densely populated tourism-based small island. An exploratory-descriptive approach was employed, combining field observations, stakeholder interviews, questionnaires, and secondary data analysis from March 2024 to August 2025. Data were analyzed through triangulation methods, descriptive statistics, and qualitative synthesis. The study reveals a critical paradox that despite strong community acceptance and established infrastructure comprising four wastewater treatment plants serving 831 house connections, the system faces severe environmental challenge. Ammonia and total coliform exceed quality standards by up to 163 and 137 times. Technical challenges include overcapacity in high-demand zones, equipment failures, and incomplete service coverage, while institutional monitoring remains weak. Socially, most residents lack wastewater knowledge yet report high satisfaction based on visible improvements. This reveals that community acceptance alone cannot serve as a reliable indicator of system success. The study also demonstrates that small island wastewater management requires integrated solutions addressing interconnected challenge across all dimensions simultaneously.

Status keberlanjutan keramba jaring apung di Danau Rawa Pening pada dimensi ekologi berdasarkan pendekatan RAPFISH

2025-12-31T13:46:13+07:00

Floating net cages (KJA) aquaculture is an important livelihood source for local community, but it also contributes to eutrophication in Rawa Pening Lake. So, it is necessary to ensure that KJA management is carried out based on the sustainable development principles to minimize the environmental impacts. This study aims to assess the sustainability status of KJA management in Rawa Pening Lake from the ecological dimension. Data were collected through interviews, direct observation, direct measurement and literature study based on following attributes; water quality, water fertility, environmental conditions, biosecurity and fish health. Then, data that has been scored were analyzed by Multi-Dimensional Scaling (MDS) using the RAPFISH application embedded in Ms. Excel). The results showed the KJA sustainability index is 49,567 (poor sustainability category). The most significant attribute of KJA sustainability is water nutrient content, i.e. N:P ratio (leverage = 4,129). It is concluded that the management of KJA in Rawa Pening Lake has been not carried out based on sustainable aquaculture management principles. Therefore, management strategies focusing on controlling water nutrient levels are urgently required to ensure the sustainability of KJA in Rawa Pening Lake.

Life cycle assessment of coal-based power plants: impacts on urban carbon footprint and externality costs

2025-12-31T17:26:16+07:00

Indonesia’s economic growth is strongly driven by industrial activities concentrated in large urban areas, resulting in high energy demand. Approximately 40-70% of Indonesia’s energy is supplied by coal combustion, contributing significantly to carbon emissions and accelerated global warming. The coal used would still be main source in the future energy of Indonesia especially in cities. This study proposes to estimate the carbon emission and environmental cost (EC) of power plant life cycle use benefits transfer method, while also accounting air = and water pollution. The results show that during 2010-2020, the EC for GHG emission is about 9 to 19 billion US$, while EC for air pollution is about 1.56-5.37 billion US$. Water pollution averaged 0.002658049 g/TWh for phenol and 9.16425 g/TWh for total COD. Then, the total water depletion is estimated to be an average of around 4.9 billion m³/MWh. Jakarta itself has a carbon footprint of 25,755 tons of CO₂ and produces external cost of US$ 3,249,506. This study highlights the urgency of reducing carbon emissions through technological innovation, strengthened energy policies and enhanced public energy literacy, with positioning cities as key drivers of the transition toward cleaner energy systems.

Elektrokoagulasi dalam pengelolaan air gambut: studi komparatif elektroda aluminium dan besi

2025-12-31T18:54:59+07:00

Water is essential for human life, yet several regions in Central Kalimantan face difficulties in accessing clean water and rely on peat water for daily needs. Peat water is generally unsuitable for drinking and sanitation purposes due to its poor quality. Its usage can lead to various health issues, such as digestive disorders skin diseases, tooth damage, and severe risks of heavy metal poisoning. One effective method to improve the quality of peat water is electrocoagulation. This study aims to investigate the effect of electrode variations using Al and Fe in treating peat water. Peat water samples were collected from Sebangau District, Palangka Raya, Central Kalimantan, in June 2024. The study analyzed water quality parameters, including TDS, pH, turbidity, color, COD, and dissolved Fe. The results showed that electrocoagulation increased pH to near-neutral levels and reduced turbidity, color, COD, and dissolved Fe, except for the Fe-Fe electrode combination, which caused an increase in TDS, color, and dissolved Fe. The Al-Al electrode combination proved to be the most effective in improving peat water quality.

Trajektori perubahan tutupan vegetasi di Pulau Sumatra berbasis analisis spasio-temporal

2025-12-31T19:22:26+07:00

Land cover change on Sumatra Island has accelerated rapidly over recent decades, marked by extensive tropical forest deforestation, widespread peatland degradation, and increasing disaster occurrences. Spatio-temporal analysis using multi-temporal satellite data provides valuable insights into the trajectories of vegetation cover change in this region. This study synthesizes findings on patterns of forest conversion to other land uses (plantations, agriculture, and infrastructure), as well as vegetation recovery patterns following fire events, particularly in peatland areas. The results reveal several dominant change trajectories: (1) deforestation followed by conversion to agricultural and plantation land, (2) cyclical changes in plantation forests, including planting, harvesting, and replanting phases, and (3) natural secondary regeneration on abandoned land after deforestation. Furthermore, in cases where deforestation is driven by land and forest fires, fire frequency plays a significant role in shaping vegetation succession pathways. Areas burned only once are able to recover toward near-original conditions after several years, whereas areas subjected to repeated fires exhibit slower recovery and tend to be dominated by shrub vegetation. These findings highlight the importance of sustainable landscape management informed by spatio-temporal data, including controlling deforestation and restoring peatlands through rewetting and vegetation rehabilitation, to prevent further degradation and support long-term ecosystem recovery.
