Abstract

This study aims to analyze the volume, weight, composition of organic waste, the characteristics of C/N, moisture content, and biodegradability fraction as a reference for biodegradability potential. Using the load count analysis method—based on modifications of SNI 19-3964-1994 and the UN-Habitat Wise Waste Cities Tools (2010)—researchers measured the daily waste generation, which amounted to approximately 11,967±2,528 liters in volume and 1.91±0.4 tons in weight. The organic waste primarily consisted of dry leaves (53%), household waste (25%), green manure and grass (17%), and vegetable waste (5%). Laboratory tests revealed the waste had a carbon-to-nitrogen (C/N) ratio of 62.07%, a moisture content of 66.76%, and a biodegradability fraction of 7.6%. These values do not align with raw material composting standards, indicating the need for waste treatment before composting. To enhance the composting process, the study recommends separating green (nitrogen-rich) and brown (carbon-rich) materials, prioritizing the green portion as the main composting input, and drying the material initially to reduce moisture to 40–45%. Composting is highlighted as a simple, eco-friendly solution for managing organic waste, contributing to soil fertility, structure improvement, and supporting sustainable agricultural practices.

Abstract

Global warming, driven in part by livestock manure emissions, poses a major environmental challenge. Refuse Derived Fuel (RDF) offers a waste-to-energy solution by converting solid cow manure into an energy source. This study investigates the impact of Bacillus sp. inoculation on the bio-drying process of cow dung. The main challenge in processing cow manure into RDF is ensuring the moisture content and calorific value meet the minimum RDF standards. Therefore, a bio-drying process is carried out on cow manure to achieve these required standards. Bio-drying performance was assessed based on drying time, moisture content, pH, and calorific value. The results show that inoculation with Bacillus sp.. at 10⁶ log cfu ml⁻¹ kg⁻¹ yielded the most efficient outcome, achieving the fastest drying time (12 days), lowest moisture content (9.64%), optimal pH (7.8), and highest calorific value (2,656.5 kcal/kg). The findings confirm a direct link between moisture reduction and calorific improvement. Hence, bio-dried cow dung treated with inoculation of Bacillus sp. 106 log cfu ml-1 Kg-1 is recommended as a viable RDF material.

Abstract

Climate change has become a serious threat to all humans, with impacts already being felt throughout the planet. One effort in climate change education is to improve students' climate literacy and climate change awareness. This study aims to measure climate literacy and climate change awareness of vocational high school students and analyze the relationship between aspects of these two variables. The instrument used was a questionnaire with a 5-point Likert scale processed with descriptive statistics and Pearson correlation analysis. The results from 295 respondents showed that the average climate literacy was in the high category (3.50), while climate change awareness was in the medium category (3.40). However, both showed significant gaps in each aspect. The results of the correlation analysis showed a significant relationship between attitudes and behavior, both in climate literacy (r = 0.323) and climate change awareness (r = 0.142). Climate change education not only conveys information in the form of knowledge but also includes efforts to strengthen attitudes that can encourage sustainable climate-friendly behavior. The results of this study will be the basis for developing climate change teaching materials in vocational high schools to improve students' climate literacy and climate change awareness.

Abstract

Increased water usage leads to higher levels of wastewater discharged into the river, which reduces river’s quality as the amount of contaminants entering increases. One way to reduce the burden of contaminants discharged into the river is through phytoremediation with constructed wetlands in domestic wastewater (grey water). The objective of this study is to determine how the number of umbrella sedge plants, residence time, and media type affect domestic wastewater parameters, including BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solid), NH₃-N (ammonia), and PO₄ (orthophosphate). The study used a Randomized Block Design (RBD) with the following treatment factors: substrate type (activated carbon and quartz sand), number of plants (0, 4, 8, or 12 clumps), and retention time (0, 1, 2, 3, or 4 days). Statistical analysis was performed using a t-test, ANOVA, and regression at a 5% significance level. The results showed that activated carbon, 12 clumps of plants, and a residence time of four days were more effective in reducing TSS, BOD, COD, and phosphate content but less effective in reducing ammonia. Results from the fourth day showed that all pollutant levels were below quality standard limits and could be released into the river.

Abstract

The Putri Cempo landfill serves as the final disposal site for organic and inorganic waste. Waste from the landfill can dissolve and settle in river sediments, potentially accumulating heavy metals like iron (Fe) and manganese (Mn), which bind easily to organic matter. This study aims to determine the content of Iron (Fe) and Manganese (Mn) in rivers around the Putri Cempo landfill. The concentration of Fe and Mn was analyzed using Atomic Absorption Spectrometry (AAS) referring to SNI 6989.84:2019,   with sediment sampling conducted in rivers around the Putri Cempo landfill. Sediment sampling was conducted in these rivers, revealing Fe levels of 1519.414245 mg/L and Mn levels of 130.033 mg/L. Analysis indicates that Fe concentrations exceed the established quality threshold, while Mn levels remain below it. Heavy metals like Fe and Mn negatively impact abiotic and biotic environments, including human health and agricultural productivity. Elevated heavy metal levels disrupt ecosystem balance and pose health risks, making their management crucial. Reducing heavy metals in river sediments near the landfill is essential. Remediation efforts using bioremediation and phytoremediation technologies can help mitigate these impacts. Ongoing efforts are necessary to control heavy metal contamination in river sediments, ensuring ecosystem stability and public health.

Abstract

Coffee liberica is an economically important yet under-researched coffee species in Indonesia. This study evaluated the individual and combined effects of Starbo-AFE compost and volcanic ash on vegetative growth and physiological performance of C. liberica in Jambi, Indonesia. A two-factor factorial experiment arranged in a randomized complete block design tested three compost rates (0, 250, and 500 g plant⁻¹) and three volcanic ash rates (0, 250, and 500 g plant⁻¹) with three replications. Measured variables included leaf area, primary branch diameter, number of fruiting branches, chlorophyll content, and soil chemical properties. Starbo-AFE compost significantly increased leaf area and branch diameter (p < 0.05), with the highest values at 500 g plant⁻¹, increasing by 54.6% and 17.5%, respectively, compared with the control. Volcanic ash alone showed no short-term effect; however, its combination with compost resulted in the highest chlorophyll content, indicating a synergistic response. Compost improved soil total N and organic carbon, while volcanic ash enhanced potassium availability and potential pH buffering. Overall, applying 500 g Starbo-AFE compost per plant effectively promotes early vegetative growth of C. liberica on peat soils, with volcanic ash contributing to longer-term soil fertility improvement.

Abstract

Climate change is a global issue at present affecting the whole world, including tropical countries like Indonesia. Previous studies have indicated that changes in these conditions have grave impacts on hydrological disasters. Therefore, the pattern of climate change needs to be analyzed for the feasibility of adaptation and mitigation in the future. This present study developed analyses into the trend in temperature variation over East Java both on an annual and daily time scale. Observation data within a long period from 1985 to 2023 was used for comprehensive results. Methods applied include linear regression, the Man-Kendall test, and Sen's Slope test. The new finding that emerged for the temperature variable was that the increase in temperature went over the global and national averages and consistently showed a significant increasing trend across the study area. However, the rainfall variable revealed different results in highlands, where the rainfall intensity decreased-in SDII and R100, inversely proportional to coastal areas. It means that climate change does not occur uniformly everywhere but varies spatially. These findings raise a case for climate change mapping to formulate appropriate adaptation and mitigation strategies.

Abstract

Bandung metropolitan region confronts escalating flood threats (2014-2024), yet oceanic climate-rainfall relationships remain uninvestigated. Our study investigates interannual climate variability influences on extreme precipitation and flooding utilizing historical records and GPM-IMERG satellite measurements validated at 90.4% correlation with BMKG. Bojongsoang (117 events), Lembang (49 events), and Braga (42 events) emerge as highest-risk areas. Peak flooding in January 2020 (15 events) coincided with La Niña and negative IOD phases. Wet season daily maximum rainfall averages 62 mm versus 41 mm in dry season, with heavy rain days of 36 versus 8 days. La Niña increases heavy rain days to 62.5 days compared to El Niño (38.6 days) and extreme rainfall to 399.6 mm versus 244.2 mm. Negative IOD enhances daily maximum to 76.8 mm versus 56.8 mm during positive phases. Flood months show 81.3 heavy rain days versus 14.4 in normal months. Early warning thresholds established at >70 mm daily maximum, >60 heavy rain days, and >400 mm extreme precipitation.

Abstract

Environmental Management Accounting (EMA) has gained attention, yet its use in grassroots waste management remains limited, especially in communities with scarce resources. This study explores how Community driven Material Recovery Facility (CdMRF), or known as waste bank, Mitra Kita in Blitar, Indonesia, applies EMA principles in its daily operations. The focus is on how local groups adapt accounting practices to stay accountable, transparent, and sustainable despite financial and operational constraints. A qualitative case study was conducted through interviews, observations, and document analysis, supported by triangulation and member validation. Findings show that the CdMRF develops practical financial routines recording expenses, calculating unit costs, and preparing semiannual reports which strengthen transparency and trust among members. Community participation plays a central role, as routine activities generate financial, social, and ecological value. However, long-term sustainability is challenged by limited managerial skills, dependence on key leaders, and fluctuating waste prices. This study expands EMA discussions by shifting attention from formal institutions to community initiatives in developing contexts. It demonstrates that simplifying accounting can make environmental management more grounded and adaptable. The findings offer guidance for policymakers seeking to strengthen CdMRFs and similar programs within broader circular economy and sustainability efforts.

Abstract

In the context of global warming, the transition from fossil fuels to renewable energy is crucial to reduce carbon emissions and achieve the Sustainable Development Goals. From 1990 to 2022, this study examines new energy consumption in Indonesia and examines its relationship with GDP, foreign direct investment (FDI), urbanization, carbon emissions (CO2), the exchange rate, and subsidies received. To determine the short- and long-term impacts, the ECM is used. In the short term, economic growth has a positive and significant effect on energy consumption; however, in the long term, the negative effect becomes more pronounced. Direct investment (FDI) has no significant effect on renewable energy consumption, creating a negative long-term trend. There are significant positive and negative dampening effects of urbanization on new energy consumption in the long term, but no significant short-term effects. Energy consumption, carbon emissions have a significant negative effect. The solution to construction and environmental challenges in Indonesia is to increase the capacity of renewable energy sources.
