Semiochemicals in integrated pest management: Molecular chemistry, biosynthesis mechanisms, and application in sustainable agricultural systems
No full textBackground: Semiochemicals, including volatile and non-volatile organic compounds used in insect communication, offer environmentally friendly alternatives to broad-spectrum pesticides. In particular, sex pheromones have gained prominence in Integrated Pest Management (IPM) due to their species-specific action and reduced ecological impact. Understanding their chemical structures, biosynthetic pathways, and olfactory mechanisms is essential to optimize their application across diverse crop systems. Methods: This study presents a comprehensive review of 15 peer-reviewed publications (2010–2025). It synthesizes findings on pheromone chemistry, enzymatic biosynthesis pathways, olfactory reception mechanisms, and field-level applications. The analysis integrates molecular characterization, biochemical pathways, and empirical performance data from 35 major agricultural pests to evaluate efficacy and economic impact. Findings: Lepidopteran sex pheromones primarily consist of Type I (C₁₀–C₁₈ unsaturated alcohols, aldehydes, acetate esters; ~75%) and Type II (C₁₇–C₂₃ polyunsaturated hydrocarbons; ~15%) compounds. Biosynthesis involves key enzymes such as ACC, FAS, Δ12-desaturase, and FAR. Olfactory detection occurs via GPCR-mediated signal transduction in antennal sensilla. Field evidence shows pheromone-based strategies—monitoring, mass trapping, mating disruption, and attract-and-kill—achieve 60–95% pest suppression while reducing pesticide costs by an average of 59%. Controlled-release formulations enable sustained delivery for 30–120 days. Conclusion: Semiochemical-based IPM represents a scientifically validated, cost-effective, and environmentally sustainable pest control strategy. By targeting species-specific communication systems, it reduces chemical dependency while maintaining high suppression efficiency. Novelty/Originality of this Article: This review integrates molecular chemistry, enzymatic biosynthesis, neuro-olfactory mechanisms, and large-scale field validation into a unified analytical framework. By linking mechanistic biochemical insights with applied agricultural performance data, it strengthens the scientific foundation and practical justification for semiochemical-driven IPM as a sustainable alternative to conventional pesticide regimes
Integrating adsorption mechanisms and circular economy principles: A systematic conceptual review of fly ash-based magnetic composites for sustainable dye removal
No full textBackground: The uncontrolled release of synthetic dyes into aquatic ecosystems presents serious ecological and public health risks due to their persistence, toxicity, and resistance to biodegradation. Conventional treatment methods often lack sustainability and cost efficiency. To address this challenge, integrative strategies are needed that combine adsorption technology with circular economy (CE) principles, particularly through the valorization of industrial waste such as fly ash into functional magnetic composites. Methods: This study employs a PRISMA-guided systematic review of fifty peer-reviewed articles published between 2020 and 2025 and indexed in Scopus and Web of Science. The analysis integrates adsorption theory, materials engineering, and circular economy frameworks. It also incorporates Life Cycle Assessment (LCA) and Techno-Economic Analysis (TEA) perspectives to evaluate environmental and economic performance. Findings: Surface modification of fly ash with Fe₃O₄, TiO₂, or biochar enhances surface heterogeneity, active site density, magnetic recoverability, and regeneration capacity. Dye removal primarily occurs through electrostatic interactions, hydrogen bonding, and π–π stacking. Magnetic properties enable efficient separation and reuse. LCA and TEA analyses indicate that these composites achieve high adsorption efficiency with lower costs and reduced carbon footprints compared to conventional adsorbents. The synthesis demonstrates how waste-derived materials can support both pollution control and resource circularity. Conclusion: Fly ash-based magnetic composites represent an eco-efficient and sustainable solution for dye-contaminated wastewater treatment. Integrating material innovation with circular economy strategies strengthens waste valorization, reduces environmental burdens, and supports sustainable industrial systems. Novelty/Originality of this Article: This study introduces a unified conceptual framework that bridges micro-level adsorption mechanisms with macro-level sustainability transitions. By integrating adsorption science, sustainability assessment, and circular economy theory, it offers a comprehensive interpretive model linking material innovation to systemic environmental transformation and global sustainability goals
Discursive construction of environmental sustainability in the 2024 Indonesian presidential debate: Critical discourse and ecolinguistic analysis
No full textBackground: Environmental sustainability has emerged as a contested discursive arena within Indonesia’s contemporary political communication, particularly during the 2024 presidential debates where competing visions of development, ecological ethics, and national progress converge. This study examines how sustainability is linguistically constructed and ideologically negotiated through an integrated framework combining Critical Discourse Analysis and ecolinguistics. Drawing on a corpus of official debate transcripts, the research analyzes lexical patterns, metaphors, narrative structures, and discursive strategies that shape competing sustainability imaginaries. Methods: Quantitative corpus mapping identifies the prominence of key environmental lexemes, while qualitative interpretation reveals how technocratic and justice-oriented discourses legitimize divergent pathways toward ecological transition. Findings: The findings indicate that sustainability is predominantly framed through technocratic modernization narratives, with hilirisasi functioning as a master signifier that aligns environmental rhetoric with economic rationality. In contrast, agrarian and ethical discourses introduce counter-narratives grounded in stewardship, moral accountability, and socio-ecological justice. These discursive tensions demonstrate how political language actively shapes sustainability governance by influencing policy legitimacy, public imagination, and the perceived boundaries of environmental action. Conclusion: The study concludes that sustainability within the debates operates simultaneously as ideological performance and governance narrative, reflecting broader struggles between neoliberal developmentalism and ecological ethics in the Global South. Novelty/Originality of this article: By integrating CDA and ecolinguistic perspectives, this research advances critical sustainability discourse studies and highlights the importance of linguistically informed approaches to environmentally responsible political communication
From vulnerability to resilience: Community-based strategies in urban informal settlements
No full textBackground: Increasing urbanization has resulted in a faster growth of slum population. The main triggering factor behind the rapid urbanization is migration of people from rural to urban area. Many of these people are jobless, capital-less, homeless and have no other alternative other than to live in the slum areas. They live totally in an informal settlement way. The main objectives of this study are to identify the vulnerabilities of urban slum dwellers and to find out appropriate measures for reducing vulnerabilities to ensure resiliency. This research is conducted in Palashpur slum of Barisal city. Methods: This research is basically based on primary data collection and partially on secondary data collection. Mainly Vulnerability to Resilience (V2R) framework is used for the research and FEMA model is used for the prioritization of vulnerability. There are 100 questionnaire survey and 3 Focus Group Discussions (FGD) were conducted. Findings: the existing human induced hazards in this slum are fire, mismanagement of waste and conflict. FEMA model has given the highest vulnerability for the mismanagement of waste and then fire, water logging and last of all conflict. So, this slum area is mostly vulnerable for these human induced hazards and mostly vulnerable for mismanagement of waste. So, proper resilience measures like awareness raising, encouraging people for using reusable bags, providing alternative livelihood options, burying electricity lines, establishing proper drainage system, strengthening social relationship etc. can reduce the vulnerability of the hazards. Conclusion: Moreover, existing organizations and Govt. should set their policies and plans according to proper resilience measures based on existing vulnerabilities and implement them in an integrated approach considering good governance. Novelty/Originality of this article: If any organizations or, Government desire to run any project for the development of this slum, they will get a clear and concise idea on which project will be fruitful for the slum. The study will also enlighten the stakeholders on how to involve community and integrate existing hazards vulnerability reduction strategies with development activities
Time and cost efficiency analysis of shotcrete and retaining wall methods for landslide disaster mitigation
No full textBackground: The construction industry in Indonesia, particularly in the city of Yogyakarta, is experiencing rapid development along with the increasing demand for educational infrastructure. In projects that involve challenging topographical conditions, the selection of an appropriate earth retaining structure method becomes a critical technical and managerial decision. This study aims to compare the cost and time efficiency between two widely used methods in retaining wall construction, namely the conventional masonry retaining wall method and the shotcrete method, in the Universitas AMIKOM Yogyakarta development project. Methods: The analysis focuses on direct and indirect costs, project duration, productivity, and critical path determination using the Critical Path Method (CPM). Data were obtained from project planning documents, detailed engineering drawings, Bill of Quantities (BoQ), and scheduling data developed using Microsoft Project. Findings: The results of the analysis indicate that the shotcrete method provides significant advantages in terms of time efficiency, with a project duration of approximately 358 working days, which is 42 days faster than the retaining wall method requiring around 400 working days. However, from the cost perspective, the shotcrete method results in higher total expenses, amounting to Rp15.526 billion compared to Rp15.187 billion for the retaining wall method, or approximately 2.24 percent more expensive. Additional analysis of indirect costs shows that the longer duration of the retaining wall method increases monthly overhead expenses, while the shotcrete method requires higher technical and equipment costs. Conclusion: Therefore, the retaining wall method is considered more economical, whereas the shotcrete method is superior when project acceleration is prioritized. The findings of this study provide practical guidance for project managers and decision makers in selecting the most appropriate method based on project objectives, budget limitations, and time constraints. Novelty/Originality of this article: This study uniquely combines cost, time, productivity, and CPM analysis to provide an integrated evaluation of masonry and shotcrete retaining wall methods, offering practical decision-making guidance for complex construction projects
The effect of education, training, and work experience on the employment probability of people with disabilities in Indonesia
Get PDFBackground: The significant gap in labor force participation among Indonesia's 22.5 million persons with disabilities poses an urgent challenge to inclusive development, despite the existence of affirmative policy frameworks. This study aims to analyze the influence of human capital, measured by education level, training, and work experience, on the probability of employment among persons with disabilities. Methods: This study uses a mixed-methods approach, processing quantitative data from the February 2024 National Labor Force Survey (Sakernas) with a logistic regression (logit) model and reinforced with qualitative analysis through in-depth interviews. Findings: The results of the study show that higher education and participation in job training significantly increase the probability of employment for people with disabilities. However, this study reveals a crucial contrasting finding: secondary education has no significant effect, while work experience and residence on the island of Java are negatively correlated with employment opportunities. Qualitative interviews explain this paradox, in which systemic discrimination, stigma, and structural barriers in the workplace effectively negate the benefits of human capital. Conclusion: Investment in human capital (supply side) is important but insufficient if not balanced with intervention on the demand side. The main barriers to the inclusion of persons with disabilities in the workforce lie in discriminatory practices by employers and the lack of an accommodative work environment. Therefore, policy recommendations must shift from merely training individuals to strict law enforcement, incentives for proper accommodation, and changes in corporate culture to create a truly inclusive job market. Novelty/Originality of this article: This study uniquely combines recent Sakernas 2024 data and mixed methods to reveal how discrimination and structural barriers undermine human capital returns for persons with disabilities in Indonesia
The application of high-density polyethylene floating docks to improve the connectivity of small islands
Get PDFBackground: A pier is an essential infrastructure in maritime transportation and inter-island connectivity. However, conventional piers are often less flexible, environmentally harmful, costly, and require regular maintenance, making them inefficient for remote islands. As an alternative, HDPE floating docks offer advantages in cost, installation speed, durability, and ease of maintenance. Southeast Sulawesi has around 651 islands, 86 of which are inhabited and have great potential in the fisheries and tourism sectors. Unfortunately, many piers in this region are unusable due to budget limitations and difficult construction access. HDPE floating docks can serve as a solution and even be utilized as platforms for water sports and recreation, supporting tourism development. Despite their potential, the application of floating docks remains limited. This study aims to design a floating dock made of HDPE as an alternative pier for islands with limited access. Methods: The design approach is based on technical analysis of local water conditions, including bathymetry, wave characteristics, and vessel activity loads. Findings: The HDPE structure has proven to be superior to concrete piers, mainly due to its modular and flexible form that allows for easy expansion. This makes HDPE floating docks an effective and practical solution for improving accessibility in remote island regions. Conclusion: This study finds that HDPE floating docks are a cost-effective, durable, and adaptable solution for improving inter-island connectivity. The Liwungan Island case demonstrates their technical feasibility and positive impacts on fisheries and tourism. Aligned with Blue Economy and Smart City initiatives, HDPE floating docks offer a scalable and sustainable alternative for small island maritime infrastructure. Novelty/Originality of this article: This article presents a site-specific HDPE floating dock design tailored to the hydro-oceanographic conditions and accessibility constraints of remote islands, integrating technical feasibility with fisheries and tourism functions as a scalable alternative to conventional piers
Evaluation of child protection case in Indonesia: Exploring barriers and policy directions
Get PDFBackground: Indonesia has built a strong legal foundation for child protection, including Law No. 35 of 2014 and the Convention on the Rights of the Child, which comprehensively regulates child protection. On the other hand, there is a significant gap between legal recognition and practical concretization, which the government actualizes through the Indonesian Child Protection Commission. Methods: This study employed a descriptive qualitative method with content analysis, collecting secondary data from 2016–2024. Data were organized, analyzed, and triangulated to examine child protection cases in Indonesia, providing insights to guide policy recommendations and address structural and coordination challenges. Findings: The findings reveal institutional crumble, limited coordination between central and regional governments, a lack of trained personnel, and weak data systems as the main issues in child protection cases in Indonesia. Despite policy and budgetary interventions, legal gaps, fragmented monitoring, and cultural barriers persist, highlighting the need for harmonized regulations, capacity building, integrated data, and community engagement to strengthen child protection. Conclusion: The study concludes that legal frameworks alone are insufficient; effective child protection requires coordinated institutions, stronger local capacity, cultural transformation, and a community-based approach to ensure children’s rights are fulfilled, upholding commitments and safeguarding every child consistently. Novelty/Originality of this article: The novelty of this study highlights the scientific implications of child protection cases in Indonesia by evaluating the period from 2016 to 2024 as a reflection to protect children’s rights, providing new insights to overcome barriers, and offering policy recommendations to adequately address these issues
