Abstract

The term "electronic waste" or "e-waste" refers to a broad array of discarded electronic products and electrical appliances that have reached the end of their useful lives. These include computers, smartphones, televisions, and refrigerators. Over the past three years, the volume of e-waste has surged, from 24.9 million metric tons (MMT) in 2019 to 33 MMT in 2022, as reported by the United Nations in The Global E-Waste Monitor 2024. This increase is driven by the expansion of the electronics industry and the increased usage of electronic devices. Life Cycle Assessment (LCA) and Material Flow Analysis (MFA) are key methodologies used to assess the environmental impact and material flow of e-waste management, respectively. However, many MFAs fail to track the flow of secondary materials that are reused, recycled, and reduced in the new products. This study addresses these gaps by analyzing e-waste management trends in Asia using a systematic literature network analysis (SLNA). SLNA combines a systematic literature review (SLR) and bibliometric analysis (BA) to offer a comprehensive review from various perspectives. This study aims to identify underexplored topics and trends, provide insights that can shape future research directions, and inform government policies on e-waste management in Asia.

Abstract

Urban sanitation remains a critical public health issue, with community participation recognized as a key factor in the success of sanitation programs. This study aims to explore the multi-dimensional factors influencing community participation in the urban setting of Koja. Through a mixed-methods approach, including surveys, interviews, and observational studies, we investigated how socio-demographic factors such as age, gender, income, and occupation, as well as aspects of sanitation governance, infrastructure, and educational interventions, interplay to affect community engagement. The study revealed that while infrastructure and access are crucial, socio-economic and gender-related barriers significantly impact participation levels. Educational level emerged as a strong predictor of engagement, indicating that awareness and knowledge play a critical role in motivating community involvement. Furthermore, sanitation governance and the quality of policies and monitoring were found to be instrumental in shaping public attitudes towards participation. The research highlights the necessity for integrated and inclusive sanitation policies that address the local context and socio-economic diversity of urban populations. The findings underscore the importance of targeted educational campaigns and the fostering of collaborative community relationships to enhance participation in sanitation programs. This study contributes to the discourse on urban sanitation by providing a nuanced understanding of the complex factors at play in community-based sanitation efforts, offering insights for policymakers to improve public health outcomes.

Abstract

The Covid-19 pandemic has resulted in restrictions on people's daily activities. Including the Yogyakarta area which is famous for its tourism and education center. Changes indirectly allow changes in the rate of waste generation. The purpose of this study was to determine changes in the generation of waste generated in Yogyakarta during the pandemic and before. This study uses secondary data for data on waste generation and population in Yogyakarta City, Sleman Regency, and Gunung Kidul Regency. Analysis was performed using analysis of variance (ANOVA) with software. Waste generation in district areas tends to decrease compared to urban areas. However, judging from the rate of waste generation, the Yogyakarta City tends to decrease, while in the district it is increasing. When viewed from the ANOVA test, there was no significant change in waste generation during the Covid-19 pandemic. This also needs to be a concern where a decrease in waste generation is not always followed by a decrease in the rate of waste generation.

Abstract

This study undertakes a SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis of the proposed glass elevator installation at Kelingking Beach, a renowned tourist destination in Bali. The research draws upon diverse scholarly perspectives to offer a comparative lens on infrastructural developments in natural settings. While the glass elevator promises to democratize access, particularly for older people and those with mobility challenges, and possibly amplify economic gains, it also brings forth concerns related to overdevelopment, environmental impact, and the risk of compromising the intrinsic charm of the destination. Our findings elucidate that while there are clear strengths, such as enhanced accessibility and potential for premium pricing, there are notable challenges to consider. The weaknesses, primarily arising from potential safety concerns and the possibility of detracting from the beach's natural allure, call for thoughtful solutions. Opportunities present themselves through collaborative efforts, sustainable practices, and a reinvigorated tourism sector. The study serves as a template for policymakers and stakeholders in natural tourist destinations, aiming to integrate infrastructure without diluting the essence of the locale.

Abstract

Air is a fundamental necessity for all living beings, especially humans. However, human activities whether intentional or unintentional can degrade air quality through pollution. This study compares the performance of the K-Means and K-Medoids clustering algorithms in analyzing the air pollution load from the industrial sector in Central Java in 2021. Using a quantitative approach and R Studio software, the analysis focuses on SO₂ and NO₂ pollution data obtained from the official Central Java BPS website. The results indicate that the K-Medoids algorithm with the silhouette method yields the most optimal clustering performance, with the lowest Davies-Bouldin Index (DBI) value of 0.6201437 and 10 distinct clusters. Notably, Cluster 1 comprises districts with the highest industrial air pollution burden such as Banjarnegara Regency, which recorded 14,472 industries and NO₂ and SO₂ concentrations of 20 μg/m³ and 6 μg/m³, respectively. These findings demonstrate that clustering algorithms not only help reveal spatial pollution patterns but also provide critical insights for prioritizing targeted mitigation efforts and informing environmental policy-making in industrially active regions.
