Un sistema IoT portátil y de bajo costo para el monitoreo urbano de ruido y calidad del aire: estudio de caso en San Salvador
(UNASA, 2026) Omar Otoniel Flores Cortez
Urban noise and air pollution are increasing threats to public health and well-being. This paper presents the development and validation of a low-cost portable IoT system for real-time monitoring of noise and air quality in San Salvador, El Salvador. The system integrates digital sensors and cloud data transmission for spatial profiling of pollution levels. Results show significant differences between the historical downtown and university campus, highlighting the potential of this technology to support environmental research and policy-making in urban sustainability initiatives.
Prospectiva de la educación superior en El Salvador
(UNASA, 2026) Saúl Enrique Campos Morán
Higher education in El Salvador faces challenges within a context of social, economic, and technological transformations. This research, "Prospects for Higher Education in El Salvador," identified future scenarios to anticipate and manage these changes. The academic offerings and their capacity to respond to economic and labor market dynamics were analyzed. Using a mixed-methods approach that included surveys, a literature review, and consultations with experts, economic trends, student perceptions, and developed competencies were examined. Scenarios were constructed based on critical variables such as public investment and university-industry partnerships. Finally, strategic recommendations were formulated to strengthen the education system.
Propuesta de gestión integral de residuos sólidos en el departamento de San Salvador
(UNASA, 2026) Mario José Lucero Culi
The focus of this research is to develop a waste management proposal for the urban area of the department of San Salvador. Waste is projected to reach 2,057 tons per day by 2044. Waste collection can be divided into three categories: green for recyclables, brown for organic matter, and gray for non-recyclable materials, yielding 699 T/d, 1,193 T/d, and 165 T/d, respectively. Organic matter treated through anaerobic digestion can generate 644 T/d of digestate, which can be transformed into 161 T/d of compost, and between 25,263 and 37,363 m³ of biogas, potentially generating between 113.1 and 129.7 MW. Non-recyclable materials treated by incineration can generate 9.6 MW of electricity. Solid waste management, applied in three fractions, allows for the utilization of the potential of each component present in the solid waste.
Prácticas sostenibles en turismo, alternativa para contrarrestar los efectos del cambio climático en zonas costeras
(UNASA, 2026) Carlos Rolando Barrios
Climate change has severely impacted communities in the coastal areas of El Salvador, which is why the study addressed the reality of inhabitants and businesses located in the coastal territories belonging to the central/eastern region, departments that have not yet experienced depredation by foreign hotel and tourism companies. The proposed question was: Can sustainable practices contribute to emerging from poverty conditions in communities of coastal territories? The study was descriptive, employing quantitative and qualitative techniques. Finally, the results reflect little knowledge of sustainable practices among both inhabitants and those responsible for tourist service businesses.
