Abstract

Jakarta, the capital city of Indonesia, is located in a tropical region with abundant sunlight and high temperatures year-round. Ozone and particulate matter (PM) are critical parameters causing unhealthy air pollution. Meteorological data were obtained from the NASA Power website. This study aims to explore the relationship between ozone formation and meteorological factors in Jakarta. Ozone air quality data were measured using the Backman model 950A ozone Analyzer, which detects concentrations as low as 0.05 ppm, with measurements taken every 40 seconds. From January to October 2023, ozone concentrations increased during the dry months of May to October, with the highest hourly value recorded at 263 μg/m³. During this period, average temperatures ranged from 27-29°C, rainfall was 0.3-5.6 mm, wind speeds were 3.14-4.64 m/s, wind direction was 92-171 degrees, and air humidity was 74-82%. Significant episodes were identified on (i) May 5-9, (ii) July 12-15, (iii) September 6-7, (iv) September 13-14, (v) September 21-22, and (vi) October 29-30, 2023. Daily, monthly, and seasonal ozone variations aligned with meteorological conditions, showing higher concentrations during the dry months. Further studies, including photochemical modeling, are required to identify dominant factors causing high ozone concentrations during these episodes. Understanding NOx or VOC emission sensitivities is crucial for effective ozone abatement strategies in Jakarta.

Abstract

Coal mining can increase land degradation and deforestation, so efforts are needed to ensure land use in post-mining areas. Therefore, mining companies must carry out land reclamation to restore the important function of forests by planting sengon laut (Paraserianthes falcataria (L.)) and burflower tree (Anthocephalus cadamba Miq.). In contrast to mining, which produces emissions and carbon that contribute to global warming, land reclamation helps absorb carbon and produce oxygen for living things. Therefore, a study was carried out to estimate the carbon stocks from reclamation activities at PT. Indobara Borneo. A quantitative approach through Stratified Random Sampling was applied in this study. Carbon estimation is carried out using allometric equations. The allometric equation of Paraserianthes falcataria (L.) is Y = 0.028D2,695, while the allometric equation of Anthocephalus cadamba Miq. is Y = 0.035D2,600. The total carbon stocks for burflower tree plants are 84.51 tons/ha with a CO2 sink potential of 974.73 tons/Ha, while the total carbon stocks for sengon laut plants are 86.18 tons/ha with a CO2 sink potential of 1355.49 tons/ha. The value of CO₂ sink and carbon stock indicates that there are environmental services to restore and improve vegetation.

Abstract

System Dynamics serves as an approach to unravel behavioral patterns by exploring fundamental structures. In this study, the dynamic system was crafted using STELLA software. The research methodology involved conducting primary surveys with both farmers and conversion farmers' households to gather essential data on their perspectives, practices, and circumstances related to land conversion and food security. Through this data, the System Dynamic model was constructed to depict the interplay among key variables impacting food security, specifically focusing on Food Availability, Affordability, and Needs. The analysis revealed that the Food Affordability indicator consistently played a pivotal role in shaping these trends over the analyzed years. However, a significant discrepancy in food security levels emerged between farming and non-farming households. This divergence primarily stemmed from income inequalities within the agricultural sector, affecting the purchasing power for essential foods like rice across the village. Additionally, a concerning trend of diminishing agricultural land and a subsequent decline in food availability was observed.

Abstract

The flood events frequently impacting Samarinda City have not yet been thoroughly examined based on their intensity, particularly in the most flood-prone village in the city, East Sempaja Village. This paper employed a rigorous methodology, including K-means cluster analysis and Getis-Ord G* statistics, to reveal spatial clustering patterns based on flood intensity and residential drainage conditions in East Sempaja. The Spearman correlation was determined to identify the relationship between both factors. The present study demonstrates that using community-derived data can enhance flood disaster mitigation strategies, particularly within regions with insufficient data availability. The analysis shows that most neighborhood areas in East Sempaja have moderate to high flood intensity levels. The areas with high flood intensity are spread across the North. This paper confirms that the condition of drainage channels has a positive, yet weak, significant relationship with the level of flood intensity. Thus, optimizing drainage channels is still relevant in managing flood disasters in East Sempaja, providing practical strategies for a pressing issue.

Abstract

In recent years, the surge in nickel production, driven by the growing demand for electric vehicle batteries, has raised concerns regarding environmental consequences. The nickel mining and processing industries contribute to increased nickel levels in wastewater, presenting a serious threat to aquatic ecosystems and human health. This article emphasizes the urgency of developing effective technologies for treating nickel-contaminated wastewater. Electrocoagulation emerges as a promising method, providing high efficiency, minimal sludge production, and cost-effectiveness. The article critically and systematically reviews the potential of the electrocoagulation process in nickel removal from wastewater. In the review, we identify and analyze nearly 32 studies published from 2013 to 2023. We discuss contaminant removal mechanisms and analyze trends in the use of operational parameters. This article identifies the most commonly applied conditions: aluminum electrodes, inter-electrode spacing ≥ 1 cm, current density ≤ 10 mA/cm², initial pH 6 ≤ pH < 11, electrolysis time < 60 min, batch operation, and initial nickel concentration > 50 mg/L. This comprehensive review serves as a foundational resource for advancing electrocoagulation technology in the removal of heavy metals from nickel wastewater.

Abstract

The Eastern Crossroad is one of the national roads that connect the city of Jambi with other cities, districts, and provinces, resulting in relatively heavy traffic and frequent congestion on this road. This has led to the concentration of carbon monoxide (CO), which can result in a decline in ambient air quality. The research used a quantitative descriptive approach aimed at depicting the ambient air quality of CO on Mendalo Darat Road, which is part of Eastern Crossroad. The research revealed the highest vehicle density of 17,954 units in the morning on Tuesday, with the highest emission rate of 114,290 µg/m.s, and the lowest density on Sunday morning with 6,568 units and an emission rate of 44,207 µg/m.s. The highest accumulation of CO emission levels occurred on Tuesday evening, reaching 38,536.44 µg/Nm3. Overall, the ambient air quality of CO on Mendalo Darat Road tends to exceed the quality standards. The accumulation of increased CO emissions correlates closely with the road's national status, increased vehicle density due to high community activity, changes in the day's status (working day), and road conditions with traffic signal devices.

Abstract

Surakarta has an area of 46.72 km2 with a population of 583,961 people. The land use in Surakarta for housing is 62% and for open space is only 9.82% of the area. Meanwhile, economic growth in this city has always experienced an increasing trend, where in 2023 investment growth reached 55.82%. This study aims to determine the general picture through the causal relationship between the components of urban development and the carrying capacity of land in Surakarta. This study uses a quantitative descriptive approach. Data is obtained from identified variables which are then arranged dynamically using Causal Loop Diagram (CLD) analysis processed with Vensim software. The results show that there is a supply model (built-up area and green open space) and a demand model (population, investment, and Gross Domestic Product). The relationship between variables describes the causal relationship in Surakarta's Land Carrying Capacity divided into three rounds, namely Loop B1 (Land Carrying Capacity – Demand - Supply - Land Carrying Capacity), Loop B2 (Supply - Built-up Land - Land Conversion - Green Open Space – Supply), and Loop R1 (Population - Demand - Investment - GDP - GDP per capita – Population).

Abstract

Population growth in Pekalongan City leads to increased community activities, which in turn raises Greenhouse Gas (GHG) emissions in the transportation, waste, and domestic sectors. This study aims to inventory and project GHG emissions, develop reduction strategies, and design regulations to mitigate these emissions. The method used to inventory GHG emissions from the transportation sector is based on Tier 1 and 2 approaches, while the waste and domestic sectors use the Intergovernmental Panel on Climate Change 2006 method with Tier 1 accuracy. The results of the inventory and projection show that GHG emissions in the transportation sector will reach 455.084 Gg CO2eq by 2032. Strategies to reduce these emissions include optimizing green open spaces (RTH), rejuvenating public transportation, and developing a Bus Rapid Transit (BRT) system, which collectively are expected to reduce emissions by 1.23%. In the waste sector, projected emissions amount to 27.88 Gg CO2eq. Planned strategies, such as increasing waste service coverage to the Degayu Landfill, optimizing waste facilities, and utilizing biogas, can reduce emissions by 15.85%. In the domestic sector, projected emissions are 27.97 Gg CO2eq, with the strategy of developing community-based livestock biogas expected to reduce emissions by 0.22%

Abstract

Processed fecal sludge generated from a sludge treatment plant rich of organic content, micronutrients, and several heavy metals that might potentially exist. Composting process recognized as a promising and cost-effective method to improve the sludge quality. The composting process was carried out in this study by using modified Compost Bag with processed sludge from fecal sludge treatment plant as the main material and organic waste and dry leaves as co-composting materials. The macro-micronutrients and heavy metal concentration of the produced compost were further analyzed. The potential application was also considered by indulging the risk assessment. The main and co-composting materials were investigated in three different ratios of processed fecal sludge (S), organic waste (OW), and dry leaves (DL) to get the optimum composition that meet the compost quality standard. Compost R2 with the ratio of 50S: 25OW: 25DL as an optimum composition which resulted good quality compost with the C/N ratio of 10.29, Total P2O5 about 2.45%, Total K2O of 0.38%, and the Cu removal up to 91.17%. The produced Compost R2 has met the compost quality standard with Hazard Quotient (HQ) for non-carcinogenic effects less than 1 revealed no potential for disease-causing effects thus safe to be used in daily life.
