Abstract

Surface water in Bojonegoro Regency plays a crucial role in meeting domestic, agricultural and ecosystem needs. However, various human activities, such as excessive use of chemical fertilizers in agricultural areas, have led to a decline in water quality. This study analyses the surface water quality using the National Sanitation Foundation Water Quality Index (NSF-WQI) method based on eight parameters: temperature, TDS, pH, DO, BOD, nitrate, phosphate and fecal coliform. The results of the analysis indicate that the surface water quality status falls into the "medium" category, with index values ranging from 51 to 70. Most parameters meet the Class II quality standards set by Government Regulation No. 22 of 2021, but elevated phosphate levels indicate the potential for eutrophication caused by agricultural activities. To maintain water quality, regular monitoring, public awareness campaigns and effective management are essential to support the sustainability of water resources in this region.

Abstract

Ambient air quality is a crucial factor affecting human health and the environment. This study aims to analyse the air quality in Bojonegoro Regency through monitoring using the passive sampler method. Monitoring was conducted in four areas: industrial, office, residential and traffic zones. The measured parameters included the concentrations of nitrogen dioxide (NO₂) and sulphur dioxide (SO₂), which were then calculated to determine the Air Quality Index (AQI). The analysis results showed that the average NO₂ concentration in the first phase was 6 µg/m³, rising to 9.25 µg/m³ in the second phase. Meanwhile, the average SO₂ concentration was 11.25 µg/m³ in the first phase and 11.5 µg/m³ in the second phase. The Air Quality Index showed a decrease from 85.784 to 83.160, but remained in the "Good" category. The decrease in the AQI was influenced by increased human activities and environmental conditions such as vehicle and industrial emissions. To improve the AQI to the "Very Good" category, recommended measures include public education, energy efficiency, application of clean technologies, forest protection, shift to public transport and improvement of monitoring systems.

Abstract

Tenggilis Mejoyo Sub-district, Surabaya, has significant potential for Green Open Spaces (GOS) to support carbon emission reduction in urban areas. This study aims to analyse the carbon stock potential of GOS in the area and evaluate their role in carbon emission mitigation. Primary data were collected through field surveys measuring tree diameter and height using the allometric method, while secondary data were obtained from relevant literature. The results show that the total area of green lanes in Tenggilis Mejoyo is 33,227.5 m², with a carbon storage capacity of 275.35 tonnes. This capacity can only absorb 0.33% of the total carbon dioxide (CO₂) emissions from the transport sector in 2019, which amounted to 83,336.73 tonnes, leaving 83,061.38 tonnes/year unabsorbed. An additional 145.97 hectares of GOS are required to offset the remaining carbon emissions. This study also shows that active parks were not included in the carbon stock analysis, which are likely to increase the overall contribution to carbon sequestration. Therefore, further research on carbon stocks in active parks within Tenggilis Mejoyo is highly recommended. The results of this study are expected to serve as a basis for environmental policy planning and more effective GOS management in Surabaya.

Abstract

The tobacco industry is a strategic sector that significantly contributes to the national economy; however, its operations also generate hazardous and toxic waste (B3) that poses a risk to the environment. The objective of this study is to evaluate the B3 waste management system that has been implemented by PT. XYZ, with a particular emphasis on the reduction and management of waste, with a focus on storage practices. A descriptive methodology was employed, combining direct observation and document analysis of existing conditions, which were then compared against the provisions of the Minister of Environment and Forestry Regulation No. 6 of 2021. The evaluation employed a Likert scale to assess the level of compliance with the regulations. The findings indicated that PT. XYZ has been identified as a producer of nine distinct categories of B3 waste, with the primary sources of these materials being attributed to various production activities and maintenance procedures involving machinery. The waste reduction aspect achieved a compliance score of 62.5%, which is categorized as "Good," while the storage aspect reached 95.45%, which is categorized as "Very Good." The overall score was determined to be 78.97%. These results suggest that, despite the effective implementation of waste storage practices, enhancements are necessary in the domains of reporting and the utilization of waste reduction technologies, with the objective of aligning with the principles of sustainable development.

Abstract

The declining quality of river water due to domestic and industrial activities demands effective water treatment technologies. This study aims to evaluate the effect of varying the number of baffles in a hydraulic coagulation reactor on the removal efficiency of Total Suspended Solids (TSS) and turbidity using two types of coagulants: Ferric Chloride (FeCl₃) and Ferrous Sulfate (FeSO₄). The experiment was conducted with baffle variations of 26, 30, 34, 38, and 42, and sedimentation times of 30, 60, and 90 minutes. The results showed that increasing the number of baffles and sedimentation time improved TSS and turbidity removal efficiency up to an optimum point. FeSO₄ achieved the highest TSS removal efficiency of 97% at 42 baffles and 90 minutes of sedimentation, while FeCl₃ demonstrated more stable and high turbidity removal efficiency, reaching up to 97%. Statistical analysis using ANOVA indicated that the type of coagulant, number of baffles, and sedimentation time significantly affected TSS removal, whereas turbidity removal was more influenced by the number of baffles and sedimentation time. These findings highlight the importance of proper hydraulic design in optimizing the coagulation-flocculation process for more efficient water treatment.

Abstract

Addressing the problem of increasingly complex urban household waste requires a multi-aspect approach. This study, therefore, aimed to develop a strategy to manage household wastes in the city of Banda Aceh based on five aspects including policy, institutional, funding, community participation, and operational technique aspects. It was conducted using in-depth interviews with garbage experts and a review of national and municipal policy documents. The qualitative data obtained was processed using Nvivo software. The investigation revealed that legal foundation of municipal waste management derived from the national and city level whereas there is no legal basis at provincial and village levels. In the perspective of institutional aspect, lack of management personnel, budget allocation, and coordination among the key stakeholder have contributed to weak institutions. As regards technical operation aspect, it can be further improved by proper sorting of waste, use of temporary disposal sites, swift waste transportation, time management of waste transportation and non-single use material campaign. Therefore, these aspects need to be developed sustainably to achieve the target of 30% waste reduction by 2025.

Abstract

Green belts play an important role in reducing greenhouse gas emissions in urban areas. This study aims to determine the total carbon stock and carbon absorption capacity of vegetation along the green belt of Dr. Ir. H. Soekarno IIC Road (MERR) in Surabaya, and to analyze the extent to which vegetation can reduce carbon dioxide (CO₂) and carbon monoxide (CO) emissions produced by motor vehicles. The method used in this study involves direct measurement of vegetation parameters such as tree diameter and height, which are then processed using biomass estimation and carbon stock conversion factors. In addition, CO₂ emissions are estimated based on traffic volume data and emission factors for each type of vehicle. The results show that the vegetation in the MERR IIC green belt is able to store a certain amount of carbon and has potential in absorbing CO₂ emissions, although it is still not proportional to the total emissions produced by motor vehicles per day. Therefore, improving the quality and quantity of vegetation in urban green belts is crucial to support air pollution control efforts in urban areas.

Abstract

Liquid waste from metal-plating industries is known to contain copper (Cu²⁺), which is toxic to living organisms if not properly treated. Hydrilla verticillata is an invasive aquatic plant capable of rapid growth and heavy metal accumulation, making it a potential candidate for use in wastewater treatment through phytoremediation. This study aims to analyze the effect of the weight of Hydrilla verticillata on the reduction of Cu²⁺ concentration in metal-plating wastewater. The wastewater used in this study was effluent that had undergone preliminary treatment with the addition of lime and NaHCO₃. The experiments were carried out in a 5-liter laboratory reactor for 15 days, including a 5-day acclimatization period and a 7-day initial toxicity test (Range Finding Test). The weight variations of Hydrilla verticillata used were 75 g, 100 g, and 125 g. The results showed that Hydrilla verticillata was able to reduce Cu2+ concentration by up to 99.05% at a weight of 125 g within 15 days. This indicates that the weight of Hydrilla verticillata significantly influences the reduction of copper (Cu2+) in metal-plating industrial wastewater.

Abstract

The utilization of coffee waste as an alternative fuel is a potential strategy in supporting organic waste management and the transition towards renewable energy. This research aims to analyze the effect of variations in the composition of coffee grounds and husk, as well as the type of binder, on the characteristics of bio-briquettes, while also evaluating the greenhouse gas (GHG) emissions generated during their production process using a Life Cycle Assessment (LCA) approach. The experimental method was carried out through the carbonization process of coffee waste at a temperature of 450°C for 80 minutes, followed by mixing the 60-mesh charcoal with bentonite and pulp binders. Characteristic testing, including moisture content, ash content, calorific value, and combustion rate, referred to SNI 01-6235-2000, while the LCA analysis was conducted using SimaPro software with the IPCC GWP100 (2021) method. The results showed that the combination of 100% coffee grounds with a pulp binder produced the best performance with the lowest moisture (4.2%) and ash (1.2%) content, a high calorific value (>6,000 cal/g), and a stable combustion rate. Thus, this combination is recommended as it yields optimal quality while lowering the environmental impact of production. The carbonization stage was the largest contributor to GHG emissions (25.11 kg CO₂-eq/kg product), followed by oven drying (3.77 kg CO₂-eq/kg). These findings affirm the importance of raw material optimization and energy efficiency in enhancing the quality and sustainability of bio-briquette production.

Abstract

The increasing volume of organic waste, especially market vegetable waste and animal waste, poses a challenge in environmental management because it has not been optimally utilized as a renewable energy source. This study aims to analyze the effect of the mixture ratio of horse manure and organic waste on biogas production using the anaerobic co-digestion method. The main ingredients consist of horse manure and market vegetable waste with the addition of Effective Microorganism 4 (EM4) starter and biogas probiotics. Variations in the mixture ratio used include 20:80, 30:70, and 50:50 (horse manure: vegetable waste). The parameters observed include methane (CH₄), carbon dioxide (CO₂), and C/N ratio. The results showed that the 50:50 ratio with the addition of EM4 produced the best performance with a methane content of 58.35% and CO₂ of 41.65%. These findings indicate that a balanced mixture composition and the use of EM4 can increase microorganism activity and accelerate the fermentation process. Thus, selecting the right substrate ratio and appropriate inoculum can be a potential strategy in developing environmentally friendly biogas energy.
