Abstract

Solid waste management in Padang City is problematic due to the annual increase in waste generation, which leads to various environmental issues. This study aims to predict the most profitable waste-to-energy (WtE) treatment methods from technical and environmental perspectives that can alleviate these issues in Padang City. The study begins with analyzing solid waste generation, composition, and characteristics. Additionally, the amount of incoming waste for thermal planning is projected based on projected generation and population. The environmental implications were assessed using the LCA (Life Cycle Assessment) method. Various waste treatment methods' technical and environmental viability was evaluated, focusing on projected waste generation in 2031, estimated at 929 tons/day. The analysis of technical aspects revealed that thermal processing of mixed waste gasification is the most profitable option, requiring only 5,101 m2 of land and capable of producing 188 GWh/year while achieving the lowest LCA Single Score of 5.82E+04 Conversely, anaerobic digesters and RDF processing generate 120 GWh and 47 GWh of electrical energy, respectively, with Single Score LCA of 4.25E+10 Pt and 7.74E+09 Pt. However, the environmental impact of WtE is the most significant, primarily due to its contribution to global warming. Global warming is predominantly attributed to carbon monoxide (CO) compounds, with carbon dioxide (CO₂) being the primary emission responsible for the observed increase in global temperature.

Abstract

This study aims to analyze PM1 concentration and the correlation of PM1 concentration with meteorological conditions and traffic characteristics on Padang City Primary Arterial Roads. The research location is perpendicular to Padang City Bypass II Road which is 5m from the roadside. PM1 measurements were carried out using an EPAM 5000 real-time particulate air monitor. Measurements were made during morning rush hour (06.30-08.30 WIB), midday off-peak hours (11.00-13.00 WIB), and evening rush hour (16.00-18.00 WIB). The results showed that the average PM1 concentration and standard deviation in the morning, midday, and evening were 17.48(3.05) μg/m3, 22.87(2.76) μg/m3, and 34.60(7.68) μg/m3 respectively with the highest concentration obtained in the evening reaching 42.63 μg/m3 and the lowest concentration in the morning 12.83 μg/m3. The results of the correlation between PM1 concentrations and meteorological conditions have a reasonably strong to very strong correlation. PM1 concentrations are directly proportional to temperature and wind speed and inversely proportional to humidity. The correlation results of PM1 concentrations to traffic characteristics are directly proportional, such as traffic volume, vehicle speed, and traffic density have a reasonably strong to very strong correlation. These results indicate meteorological factors and traffic characteristics as the main contributors to road air pollution. The recommendation from this study is to optimize air quality monitoring and traffic management.

Abstract

Avocado starch has gained attention as a potential bio-based material due to its unique features that make it suitable for forming biofilms. This work thoroughly examines the changing field of research focused on using avocado starch for biofilm applications. It uses VOSviewer, a tool for analyzing bibliometric data, to uncover important insights using a database of Scopus-indexed journal publishers. This study aimed to determine research trends on the use of avocado starch for biofilm production. The Scopus database collected information on research trends in the use of avocado starch for biofilm production. To obtain search results, subject categories with titles, keywords, and abstract criteria from the use of avocado starch extraction, biofilm/bioplastic production, and biocomposite were used as a reference. Using VOSviewer, search result extraction was performed. The results of bibliometric mapping were then further evaluated. The findings of the bibliometric study are demonstrated through network visualization, overlay visualization, and density visualization. The findings indicate that starch produced from avocados has the potential to be a viable resource for manufacturing biofilms. However, further investigation is required to enhance the overall quality of the produced biofilm.

Abstract

This study intends to analyze methane gas emissions resulting in landfill procedures. The magnitude of the impact of methane gas emissions on global warming from the waste sector, it is necessary to calculate the potential amount of methane gas emissions of Padang city waste in the Air Dingin Landfill so that it can be used for new energy potential as an alternative energy to replace fossil fuels no longer as a contributor to global warming. In this study, the methodology contains systematic steps in researching to achieve research objectives, namely conducting preliminary studies and literature studies, formulating problems, and setting research objectives as well as how to collect and obtain research data. The result of this study is that the Air DIngin Landfill in Padang City is still processing open dumping, with land that has been operated around 50% of the existing land area. The high operational costs are one of the reasons the sanitary landfill system cannot be done by the Padang City Government. Methane gas produced from 2020 - 2031 in the Air Dingin Landfill is produced from scenario 1 (waste directly landfilled) which is 43,289 gigagrams of CH4 or 43,289 tons of CH4 emissions. CH4 emission scenario 2 (waste reduction by waste pickers in landfill) produced 43,267 gigagrams or 43,267 tons of CH4. CH4 emission scenario 3 (Reduction of waste at source, in the region, and in landfill) produced 40,944 gigagrams CH 4 or 40,944 tons of CH4. After converting methane gas into electrical energy, the potential electricity in scenario 1 is 84.15 megawatts, scenario 2 is 84.10 megawatts and scenario 3 is 79.59 megawatts in 2031.

Abstract

Septic tank emptying in Padang City has not been effectively implemented. Low public participation and illegal disposal of fecal sludge into drainage systems and water bodies remains common. This study aims to assess how the households manage septic tank emptying and offers strategic recommendations using a SWOT analysis. The data obtained from questionnaires given to 100 households across all sub-districts, as well as interviews with stakeholders from the Dinas LH of Padang City about current desludging programs. The emptying practices were grouped into safe and unsafe emptying. Results show that only 26,33% of households manage septic tanks properly in terms of construction, emptying, and knowledge. Based on the SWOT analysis result, the household fecal sludge management in Padang City's is situated in the quadrant II, meaning existing opportunities can be used to deal with internal weaknesses. Recommended strategies include regulatory development, capacity building, community engagement, and regular monitoring and evaluation to support the implementation of safe emptying practices.

Abstract

The amount of waste generation that increases without being accompanied by good waste management will cause pollution and decrease the aesthetic value of the environment. Non-residential waste originating from non-residential activities is also one of the contributors to waste entering the landfill. This study aims to analyze non-residential waste generation and composition as an evidence-based reference for each source in implementing the 3R concept and the Food Recovery Hierarchy (FRH). The number of sampling sets was determined at a minimum of 10% of each type of facility following SNI 19-3964-1994. Sampling was carried out on eight consecutive days with 14 sampling points in Area 1, 14 in Area 2, and 11 in Area 3. The total non-residential waste generation was 46.79 m³/day (9.49 tons/day). Organic waste dominated the composition, accounting for 35–37% as food waste, followed by plastic (24–29%) and paper (14–20%). The high proportion of biodegradable and recyclable materials indicates significant potential for composting, recycling, and food recovery strategies at the source level. Implementing source-level 3R and FRH approaches could substantially reduce landfill dependency and extend landfill lifespan. This study addresses a knowledge gap by linking source-level non-residential waste characterization with the practical implementation of the 3R concept and the Food Recovery Hierarchy. This study provides quantitative evidence to guide localized waste minimization strategies in non-residential sectors.
