Purpose: Food waste is a latent problem for society, one of the main causes being poor management of the operating processes within the food industry, which is the main reason the present research aimed to reduce raw material waste in a nectar factory.Design/methodology/approach: The methodology led to carrying out an experimental investigation where a Green Lean Six Sigma Model was applied, whose foundation was the use of tools such as Environmental Value Stream Mapping (E - VSM), DMAIC (Define - Measure - Analyze - Improve - Control), Poka Yoke and DOE (Design of Experiments), the data obtained were exposed to an inferential statistical analysis using tests such as Anderson - Darling and T-Student.Findings: As a final result, a waste reduction of 2.23% was obtained, which is equivalent to approximately 120 kg of useful raw material, in addition the environmental impact was reduced by 2.2%, waste costs were also reduced by approximately 5.5% and produced an increase in global productivity by 2.4%.Research limitations/implications: It is shown that the application of methodologies such as Green, Lean and Six Sigma in the food industry present benefits during and after the application of the model; such as preventive control of waste, standardization in processes; benefits that, in coordination with an organizational culture of continuous improvement, can significantly improve the current state of companies.Practical implications: The positive obtained results support the methodology proposed by the authors to reduce the waste of agricultural raw material. It is expected to be a benchmark for other similar organizations that seek to generate greater productivity in line with the search for environmentally sustainable operations.Originality/value: This is one of the first studies that aims to reduce the waste of raw materials in food processing companies, considering aspects of mitigating environmental impact.

Se ilustra el uso del software estadístico SPSS aplicado a la prueba Chi Cuadrado para probar independencia entre dos variables. La aplicación se realiza en la evaluación del impacto generado en la plana docente de la Facultad de Ciencias Administrativas de la Universidad Nacional Federico Villarreal en relación al uso de algunas de las herramientas de las denominadas tecnologías de información y comunicación, en el proceso de formación profesional de Licenciados en Administración.

El propósito de la investigación fue determinar la capacidad de emprendimiento de los alumnos que ingresaron a la Facultad de Ingeniería Industrial del año 2008 utilizando la de Habilidad Emprendedora, validada por Flores (UIGV, 2003). Asimismo, se analizaron los factores que marcan diferencias en esta capacidad, tales como el tipo de preparación para acceder a la universidad, el género o la procedencia de colegio de secundaria. Los resultados indican que los alumnos sujetos de estudio, de acuerdo al instrumento utilizado, presentan una habilidad emprendedora alta.

This study aims to map the evolution of pico-hydropower and Michell–Banki (cross-flow) turbine research from 2000 to 2025 through a combined bibliometric analysis and qualitative mini-review. In total, 1036 Scopus-indexed records were initially identified and refined to 922 relevant publications for analysis. Bibliometric mapping with CiteSpace, VOSviewer, and Bibliometrix identified publication trends and seven major thematic clusters (dominated by topics such as cross-flow turbine design, renewable energy integration, and asynchronous generators), while a qualitative mini-review of key studies provided contextual depth. The analysis detected 25 keywords with strong citation bursts, indicating a shift in focus over the last decade from traditional electrical regulation toward digitalization and additive manufacturing. The mini-review distilled three dominant lines of inquiry geometric design optimization, hydraulic performance characterization, and socio-economic evaluation and highlighted critical knowledge gaps, including the absence of standardized flow–head–efficiency (Q–H–η) performance data, sparse reporting of economic metrics like levelized cost of energy (LCOE), and limited high-altitude (above 3000 m) validation of pico-hydro systems. This study’s integrative approach is unique compared to prior bibliometric or technical reviews, providing a comprehensive overview of the pico-hydropower landscape and outlining a future research agenda to standardize experimental protocols, integrate economic analysis, and extend cross-flow turbine deployments to high-Andean regions.

Con base en la problemática del sector industrial, sobre la comercialización de plásticos, que se ha visto afectado por la implementación de la ley que restringe el uso y comercialización de plásticos de un solo uso a través de la implementación de la Ley N.º 30884 – “Ley que regula el plástico de un solo uso y los recipientes o envases descartables”; este artículo propuso la implementación de un nuevo modelo de producción en base al Lean manufacturing con enfoque biotecnológico en una Mype de la industria plástica. Por este motivo, se eligió un método de investigación transversal a la cadena de suministro con un enfoque sostenible mediante la aplicación de biotecnología. Esta técnica utiliza recursos naturales para elaborar productos sustitutos de los plásticos de un solo uso y lograr un producto sostenible. La metodología mpleada fue no experimental y descriptiva, elaborando una propuesta de alternativa sostenible en la producción de plásticos de un solo uso por plásticos biodegradables que cumpla con la metodología Lean manufacturing. Finalmente, la conclusión más importante de la investigación fue que, efectivamente, mediante la implementación de la metodología propuesta se redujo mermas y mejoró la rentabilidad.
