Rolando Neptalí Ponce-Macías — 2025-01-19

The energy transition towards renewable sources is necessary to guarantee universal access to electricity, especially in regions with difficulties connecting to the electrical grid, such as the province of Manabí, in Ecuador. The objective of this research was based on analyzing the main renewable alternatives available in the region: solar, wind, biogas, wood, and biodiesel; under a methodology based on documentary or bibliographic review, case studies, technical analysis and impact evaluations, through a type of positivist research where the descriptive and analytical method was used, in which specific opportunities and challenges of these technologies were identified in the Manabí context. The results show that a well-structured implementation strategy could transform Manabí into a model of sustainable energy development, improving the quality of life of its communities and protecting its environment.

Independent power system for traffic lights through solar energy in Ecuador-Manabí-Portoviejo

Jiorge Rolando Moreira-Mendoza — 2025-03-02

The need for sustainability solutions promotes the use of renewable and distributed energy sources in urban and rural applications, the energy situation in Ecuador promotes the search for alternatives for the energization of traffic lights in urban areas, the objective of the research was to analyze and design an autonomous power system for traffic lights using solar energy. It was used as an investigative, descriptive and analytical methodology. The result was that solar energy can be used to power traffic lights, guaranteeing greater autonomy and reduction in maintenance costs. Furthermore, the implementation of this technology in urban areas could be an efficient and sustainable alternative to conventional systems that depend on the electrical grid.

Integration of ICT in the administrative management of small commercial enterprises

Gema Michelle Alcívar-Vera — 2025-06-08

The research sought to integrate information and communication technologies (ICT) into the administrative management of small commercial businesses in the city of Guayaquil, in 2022. Based on the "Buenrostro model", the following categories of analysis were established to guide the study: 1) socioeconomic characteristics of the entrepreneurs, 2) basic ICT equipment, 3) use of ICT in the company's activities, and 4) difficulties in using ICT. A descriptive, observational, cross-sectional, and prospective methodology was applied based on a solely qualitative approach. The problem faced by small business owners is the lack of efficiency in processes and difficulty in accessing relevant information. The objective of the research is to describe the characteristics of the integration of ICT in the Administrative management of small commercial businesses. The study population consisted of 10 owners of small commercial businesses located in the city of Guayaquil, intentionally selected under certain inclusion criteria. Open-ended interviews and a non-participatory observation guide were used as data collection techniques. The results obtained contributed to a state-of-the-art analysis of the phenomenon analyzed for broader and more in-depth studies. Given that there are limited background information or studies on the integration of ICTs at the local level, and even more so in the business sector, it is evident that entrepreneurs are not receiving support from state institutions.
