Abstract

Indonesia, as the foremost producer of palm oil globally, faces crucial environmental challenges. Besides palm oil production plays an important role in economic growth and national development, it also has environmental consequences from the production process. Crude Palm Oil (CPO) Industries face challenges balancing economic growth and environmental sustainability. This research carries out an environmental impact analysis of CPO production with the Life Cycle Assessment method using openLCA software 2.03 with CML-IA Baseline and ReCiPe 2016 Midpoint (H). Scope of this research adopts cradle-to-gate analysis with declaration unit of 1 kg CPO product. In this analysis, it was found that CPO production had a significant impact on GWP, Terrestrial Eco-toxicity Potential, and Land Use Change. So this research also explores the environmental impact of increased Oil Extraction Rate (OER) scenario with an OER of 21% and 22% compared to OER in current production activities. The research showed that all impacts decreased when OER was increased, impacts decreased of around 3% at OER 21% and decreased of around 8% at OER 22%. These findings confirm the potential feasibility of implementation based on increasing OER in the Palm Oil Industry to achieve targets for sustainable improvement.

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

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

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

The Ministry of Public Works and Public Housing (Kementerian Pekerjaan Umum & Perumahan Rakyat – PUPR) has developed a guideline for assessing the performance of Waste Processing Sites in terms of Reduce, Reuse, and Recycle (Tempat Pengelolaan Sampah Reuse, Reduce, dan Recycle - TPS 3R) across five waste management aspects: regulations, technical technology, management institutions, finance, and community participation. The guideline includes parameters and indicators, but their definitions are not clearly specified, leading to various interpretations. This study aimed to identify the key indicators for measuring the performance of TPS 3R. The study involved defining and determining sub-indicators for each aspect using the constructive alignment concept to ensure clarity in measurement. These sub-indicators were consolidated into a set of questions for use in field data collection. The developed guidelines were applied to evaluate TPS 3R performance in West Java, using a comparative study and descriptive analysis for the evaluation. The study identified the critical indicators for each aspect as follows: (i) waste segregation for community participation, (ii) complete waste processing (sorting, organic waste processing, and inorganic waste handling) for technical aspects, and (iii) active management (waste and financial records) for management institutional aspects. These critical indicators not only influence the financial aspect but also provide economic support for the sustainability of TPS 3R.

Abstract

Advanced Oxidation Processes (AOP), such as persulfate oxidation is a promising contaminant removal agent for treating wastewater. In this study, Sidoarjo volcanic mud (VM) was applied as heterogeneous catalyst to support the persulfate oxidation process for Congo Red (CR) dye removal. The Sidoarjo volcanic mud is known to have a high iron content, making it a potential catalyst in AOP. This study was conducted under conditions of pH 2, CR 50 mg/L, and catalyst dosage 0.5 g/L  and effective reaction volume of 300 mL. This experiment was conducted by comparing three types of catalysts: unmodified volcanic mud (UVM), impregnated volcanic mud (Fe-IVM), and calcined volcanic mud (CVM). The methods were carried out by comparing two methods, namely simultaneous and sequential. The obtained CR removal values for UVM, Fe-IVM, and CVM catalysts were 83.73%, 78.86%, 51.96% for simultaneous and 84.75%, 81.72%, and 87.69% for sequential method. Whereas the UVM catalyst has the highest CR removal value with a lower adsorption value of 16.89%. The production of sulfate radical analyzed by comparing the oxidation process of homogeneous and heterogeneous catalysts. It was shown that the application of VM catalyst as heterogeneous catalyst is very promising for dye removal in wastewater treatment.
