Abstract

As the population increases, the amount of plastic waste, especially styrofoam, is also increasing. Styrofoam waste that is not disposed of and accumulates will have a negative impact on health and the environment. On the other hand, the utilization of styrofoam waste as an additional material for building materials is still very minimal. Therefore, this research aims to overcome environmental problems by utilizing styrofoam waste in making paving blocks as an alternative building material. This research uses a quantitative method to determine the quality of paving blocks produced from a mixture of styrofoam and silica fumes. The research process begins with paving blocks containing 10% styrofoam from the total sand, with variations in particle size that pass the mesh sieve of 1mm, 4mm, and 10mm. Styrofoam acts as a partial replacement for coarse and fine aggregates. In addition, silica fume was added as much as 10% of the total cement to partially replace the adhesive material. The results showed that the addition of styrofoam waste with a diameter of 1mm, 4mm, and 10mm mesh passes in paving blocks produced compressive strength values of 18.00 MPa, 29.17 MPa, and 32.34 MPa, respectively, as well as water absorption values of 6%, 4.9%, and 3.6%. The larger styrofoam shredding diameter (10mm mesh) produced the highest compressive strength value (32.34 MPa) and the lowest water absorption (3.6%), meeting SNI 03-0692-1996 and quality classification B for parking lots. The best composition is the addition of styrofoam by 10% of sand and silica fume by 10% of cement, with 10mm mesh shredding diameter. The styrofoam shredding diameter proved to have a significant effect on increasing the compressive strength and decreasing the water absorption of paving blocks. This research is expected to provide a practical solution in reducing styrofoam waste by using it as a building material, while producing paving block products that meet quality standards.

Abstract

There has been an exceedance of water quality standards in the Morowudi Village reservoir. Therefore, treatment using a combination of geotextile pretreatment and filtration is required. The objective of this study is to determine the reduction in turbidity, color, and total coliform concentrations in the Morowudi reservoir water and to identify the most optimal efficiency of each variation in reducing turbidity, color, and total coliform concentrations. The turbidity, color, and total coliform concentrations of Morowudi reservoir water were 84.9 NTU, 251 TCU, and 730,000 CFU/100 mL, respectively. This laboratory-scale study used geotextile pretreatment as the initial filter, followed by filtration. The geotextile pretreatment reactor is a cylindrical tube with dimensions of 40 cm x 50 cm. Treatment is conducted in stages from the geotextile pretreatment reactor to filtration. The filtration reactor has a length of 10 cm, width of 10 cm, and height of 90 cm. In the filtration reactor, variations in the height of silica sand, zeolite, and activated carbon media are tested. In variation 1, the heights of the silica sand, zeolite, and activated carbon media were 30 cm, 20 cm, and 20 cm, respectively. In variation 2, the heights of the silica sand, zeolite, and activated carbon media were 20 cm, 30 cm, and 20 cm, respectively. Based on the research results, in variation 1, the average reduction in turbidity concentration was 19.39 NTU with a reduction percentage of 77.16%, color concentration was 85.40 TCU with a percentage of 65.98%, and total coliform was 2.60%. In variation 2, the average reduction in turbidity concentration was 25.08 NTU with a percentage of 70.46%, color concentration was 98.55 TCU with a percentage of 60.74%, and total coliforms were 633,000 CFU/100 mL with a percentage of 13.29%. The treatment results in this study did not meet the hygiene and sanitation water quality standards.

Abstract

This research was conducted to provide data on water quality based on physical and chemical parameters around the fishpond area, Citarum Watersheds, in Karawang Regency. Water quality is a primary requirement for the sustainability of local economic activities. However, with the increasing pollution load, there is concern that water quality around the fishpond area will decline, impacting fishpond productivity, public health, and the environment. Water samples were collected at 10 points along the Citarum Watersheds using a water quality test pen. The measured physico-chemical parameters included temperature, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD). The results indicate that several physico-chemical parameters still do not meet the quality standards established by Government Regulation (PP) Number 22 of 2021. These include BOD and DO, where concentrations at all observation points exceeded the quality standards, while the COD values exceeded the standard at most points, except at stations 1-5. This exception is due to their considerable distance from agricultural activities or other community practices. The high COD concentration indicates a significant load of organic pollutants, which are suspected to originate from agricultural runoff and domestic waste. Conversely, the low DO concentration is caused by microorganisms in the water body utilizing the oxygen. These microorganisms require DO as an electron acceptor in their metabolic processes, leading to a decrease in DO levels in the water and a corresponding increase in BOD. The BOD/COD ratio at the study site ranged from 0.46 to 0.5, meaning the pollutants are categorized as biodegradable. Therefore, it can be concluded that the waters in the downstream region of the Citarum River are still suitable for use in freshwater aquaculture activities.

Abstract

Ecodrainage planning in Pasirjambu District, Ciwidey District. In 2017 the district experienced a fairly high rain intensity and there was a change in the function of the forest area in the upstream area, so that the Ciwidey Sub-watershed experienced an overflow. To overcome this problem, an environmentally friendly drainage is planned by adding complementary structures, namely a reservoir pool as a flow barrier. The available surface runoff discharge is 11.68 m3/s at outlet S.8. The discharge will be reduced by 8 m3/s into the reservoir with a storage volume of 2,208 m3. Meanwhile, another reservoir originating from the Ciwidey River with a discharge of 21.007 m3/s requires a storage volume of 210.07 m3. The water stored in the embung will be used for irrigation purposes, so that this reservoir can reduce areas prone to flooding and prone to inundation but can also increase rice production as a livelihood for the community.

Abstract

The waste management problem in Indonesia continues to escalate alongside population growth and urbanization, with waste generation reaching 68 million tons annually, including 15% plastic waste that is difficult to decompose. This study aims to analyze community-based waste management through a system dynamics modeling approach applied to participants of the Zero Waste Learning Class (BZW), which adopts the 3AH principles (Prevent, Sort, Process). Using Causal Loop Diagram (CLD) and Stock and Flow Diagram (SFD), this study maps the interactions between variables such as the number of participants, environmental literacy, waste generation, and the effectiveness of prevention, sorting, and processing activities. Data was collected through surveys of 492 BZW alumni and secondary data on waste management. Simulations were performed using Powersim Studio 10 software, with model validation conducted using the Absolute Mean Error (AME) method, yielding an error rate of 2%, indicating a valid model. This study examines four policy scenarios: Business as Usual (BAU), improved environmental literacy, enhanced waste prevention, and optimized waste processing. The simulation results show that the optimal scenario is increasing the capacity for organic and inorganic waste processing, which successfully reduced residual waste to -56.87 tons by 2030. Furthermore, the amount of sorted waste reached 100% of the generated waste. This study concludes that the system dynamics modeling approach is effective in supporting strategic decision-making for community-based waste management and provides recommendations to enhance environmental literacy and waste processing efficiency to achieve sustainability.

Abstract

Waste management has become a serious problem across all urban areas in Indonesia, where the main issue is the lack of treatment at the source. One of the best solutions to process waste is at the source, for example, through composting. This study aims to design a compost reactor and analyze the nitrogen (N), phosphate (P), potassium (K), and C/N ratio of the composting products. In this study, the material used was household organic waste from the Griya Taman Asri Housing Residence Block F, which had been sorted into three categories: organic, inorganic, and non-3R. The composting process was carried out aerobically with the addition of EM4 starter, using a plastic drum reactor with holes on each side. Inside the drum, a pipe with holes was installed, while a filter and tap were placed at the bottom. During fermentation, temperature and pH were measured every 3 days. After calculating the amount of waste generated, a reactor with a capacity of 60 liters was produced. The N content was 1.821%, P was 1.131%, K was 3.516%, and the C/N ratio was 19.97, with a compost maturation period of 22 days. Based on the N, P, and K content of the compost product, compared with the N, P, and K content standards of the SNI compost quality standard and market compost quality standards, the compost produced in this study is considered of good quality.

Abstract

Indonesia is one of the world's largest contributors to carbon emissions, primarily from the fossil-fueled land transportation sector. The COVID-19 pandemic demonstrated that a reduction in mobility could significantly decrease emissions, especially in densely populated areas with suboptimal public transportation systems. In addition, inequality in population distribution and differences in socioeconomic characteristics between regions lead to environmental pressures that vary across Indonesia. This study aims to analyze the impact of population mobility and socio-economic indicators on carbon monoxide (CO) emissions in Indonesia during the unique pandemic period of 2020-2022. The method used is the Random Effect Model for panel data regression. The results show that mobility to workplaces and stores, economic growth, and poverty levels have a significant negative effect on emissions. Conversely, mobility in residential areas and population density have a significant positive effect. The variables of mobility to transit stations and Foreign Direct Investment (FDI) were found to be not significant. These findings point to the need for low-emission transportation and household energy efficiency policies that are responsive to mobility dynamics and socio-economic characteristics of the community.

Abstract

Kemambang River is located in Buduran Sub-district, Sidoarjo and plays an important role in the hydrological cycle and the lives of the surrounding community. Buduran sub-district is one of the sub-districts with high population growth. The number of industries, housing, agriculture around Kemambang River can reduce the water quality of Kemambang River. The purpose of this study was to evaluate the water quality of Kemambang River based on chemical physical parameters and macroinvertebrates as bioindicators of water quality. The research used descriptive quantitative method by conducting water sampling in 3 (three) locations, laboratory tests and analyzing physico-chemical parameters (DO, TSS, BOD, and COD) based on PP 22 Year 2021 class II quality standards and biomonitoring analysis using Family Biotic Index (FBI). The results of the physico-chemical parameter analysis showed that the Biochemical Oxygen Demand (BOD) parameter exceeded the quality standard at all research locations with the highest value at point 3 with a value of 7.10 mg/L (BOD quality standard of 3 mg/L). Dissolved Oxygen (DO) did not meet the quality standards at points 2 and 3 with the lowest value at point 3 with a value of 2.68 mg/L (minimum DO quality standard of 4 mg/L). While the Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) parameters still met the quality standards at all points. Based on the FBI calculation, point 1 produced a value of 7.20 and was included in the "poor" criteria, while points 2 and 3 with values of 5.32 and 5.40 were classified as "fair" criteria. It concluded that there were significant and very significant amounts of organic pollutants in the waters. This study illustrates the need for urgent action to improve water quality in Kemambang River.

Abstract

Indonesia, particularly DKI Jakarta, faces severe challenges regarding air pollution, with PM2.5 concentrations far exceeding the thresholds set by the WHO, placing Jakarta among the top cities with the highest levels of air pollution. This study aims to provide a comprehensive overview of air quality conditions in DKI Jakarta, classify air quality using SVM algorithm, and generate high-resolution air quality maps by integrating data from air quality monitoring stations (SPKU) and satellite imagery. The methodology involves imputation and SMOTE-Tomek Link resampling techniques to address missing data and class imbalance problems. The results indicate that air pollution levels in DKI Jakarta fluctuate throughout the 2022–2024 period. Satellite imagery data contains more missing values, however, classification models based on these data still demonstrate optimal performance. In contrast, data from SPKU shows significant improvement in model performance after resampling. Spatial maps derived from satellite data offer finer resolution and can estimate air quality in areas beyond SPKU coverage.

Abstract

Activated carbon is one of the adsorption materials commonly used to improve the quality of used cooking oil. This study aims to determine the effect of varying concentrations of phosphoric acid (H₃PO₄) as a chemical activator on activated carbon derived from red onion peel. The research data were expressed quantitatively through physical and chemical characterization, while the results of color and odor tests were presented descriptively. Activated carbon from red onion peel was successfully produced through physical activation (400 °C) and chemical activation (H₃PO₄) with concentration variations A (8%), B (12%), C (16%), and D (20%). The characterization results showed a decrease in moisture content, ash content, and volatile matter content, while the carbon content increased. Sample D met the requirements of SNI 06-3730-1995 for all physical and chemical characteristics. An increase in adsorption ability for acid value was observed in line with the increase in activator concentration. The ability to reduce peroxide value decreased in samples C and D compared to sample B, but still met the SNI 3741:2013 standard. The most optimal characterization and adsorption performance were obtained in sample D, with an acid value of 0.33% (mg KOH/kg) and a peroxide value of 8 (meq O₂/kg).
