Abstract

Background. Flooding has become one of the most persistent environmental challenges in Semarang City, driven by rapid urbanization, land subsidence, and inadequate drainage systems. Conventional flood management approaches relying solely on grey infrastructure have proven insufficient to address the increasing frequency and intensity of flood events. Green infrastructure, including urban green spaces, bio-swales, retention ponds, and mangrove restoration, has emerged as a sustainable alternative that enhances natural water absorption and resilience against hydrological stress. Purpose. This study aims to evaluate the effectiveness of green infrastructure in mitigating floods in Semarang by assessing its hydrological, ecological, and socio-economic impacts. Method. A mixed-method approach was adopted, combining quantitative analysis of hydrological data with qualitative assessments from community surveys and expert interviews. Hydrological modeling using GIS and SWMM software was employed to simulate flood scenarios under different land-use configurations. Data on rainfall, surface runoff, and infiltration rates were collected from the Semarang Environmental and Public Works Agencies. Qualitative insights were gathered from local stakeholders to evaluate community perceptions of green infrastructure effectiveness and maintenance challenges. Results. The results indicate that green infrastructure interventions reduced peak flood levels by an average of 22–28%, improved runoff retention capacity, and enhanced groundwater recharge. Neighborhoods with integrated green spaces demonstrated greater resilience during heavy rainfall events compared to those relying solely on engineered drainage. Conclusion. The study concludes that the adoption of green infrastructure offers a cost-effective and ecologically sound strategy for urban flood mitigation in Semarang. Strengthening policy integration, maintenance systems, and community engagement is essential to sustain long-term resilience.

Abstract

Increasing global food demand, climate change, environmental degradation, and the growing prevalence of biotic and abiotic stresses have intensified the need for innovative crop improvement strategies capable of enhancing agricultural productivity and resilience. Recombinant DNA technology has emerged as a fundamental tool in agricultural biotechnology, enabling precise genetic modification to develop crop varieties with improved agronomic performance, stress tolerance, and nutritional quality. This study aimed to examine the contribution of recombinant DNA technology to future crop development by evaluating its effectiveness in enhancing productivity, physiological adaptation, and sustainable agricultural performance. A mixed-methods sequential explanatory design was employed, integrating quantitative evidence obtained from molecular analyses, physiological measurements, agronomic evaluations, and multi-location field experiments with qualitative data collected through expert interviews, field observations, and policy document analysis. Findings demonstrated that recombinant DNA-derived crop lines significantly improved grain yield, biomass production, drought tolerance, salinity tolerance, pest resistance, disease resistance, nutrient-use efficiency, and grain protein content compared with conventionally bred cultivars. Qualitative evidence further indicated that successful implementation depended on the integration of molecular innovation, biosafety governance, interdisciplinary collaboration, and sustainable agricultural management. Results suggest that recombinant DNA technology functions as a comprehensive platform for developing climate-resilient and resource-efficient crop varieties rather than merely introducing isolated genetic traits. Integrated implementation supported by responsible governance provides a sustainable pathway toward future crop development, global food security, and environmentally resilient agricultural systems.
