Previous research has shown that cities present vehicular congestion. This research focuses on the development of a prototype for detecting and warning of traffic congestion using cameras with multiple sensors to identify the number of vehicles present in an area. The population of Arequipa was 87% satisfied with the perception and effectiveness of the proposed prototype. The importance of using technological advances helps to provide solutions to society by providing real-time information on faster alternative routes, based on the number of vehicles present and estimates of arrival time to avoid traffic, and an economic and financial analysis was performed so that municipalities can appreciate the profitability of using this proposal

This research focused on conducting a case study on three recycling organizations in Panama with the purpose of analyzing their core activities, materials they recycle, those that are not utilized, and identifying challenges and opportunities to improve waste management in the country. The study employed a methodology that combined literature review, and interviews conducted, both in person and via virtual platforms. Based on the gathered information, it was identified that one of the main challenges for effective recycling in Panama includes technical, economic, and financial obstacles. These barriers hinder the utilization of certain materials that could be recycled. The study concludes by offering significant observations on the current situation of recycling in Panama and proposes recommendations such as strengthening recycling infrastructure and promoting public policies to favor circular economy practices. It provides a solid foundation for future initiatives aimed at improving waste management, focusing on overcoming the identified challenges. This research not only contributes to understanding current obstacles in recycling in Panama but also lays the groundwork for concrete actions that can be taken to enhance environmental conditions and promote more sustainable practices within the country.

This study aimed to evaluate the effects of hot air drying on the protein content of dehydrated Nostoc sphaericum. A population of 5 kg of Nostoc was used, divided into two treatments: Treatment 1 (T₁) with 2 kg dried at 70 °C for 8 hours, and Treatment 2 (T₂) with 3 kg dried at 90 °C for 5 hours. After the drying process, the dehydrated samples were analyzed to determine their protein content using the Kjeldahl method. The results showed that T₂ achieved a higher protein content (34.15%) compared to T₁ (30.75%). However, a t-student t-test with a 95% significance level revealed that these differences were not statistically significant (p-value of 0.328). In conclusion, hot air drying is an effective method for dehydrating Nostoc, maintaining protein integrity despite differences in drying conditions, suggesting its viability for future applications in the food and pharmaceutical industries.

This research aims to evaluate the influence of contact time and the proportion of Zuro Zea Mays and Musa Paradisiaca peel on the removal of copper and total iron from artisanal mining effluents. These emerging technologies stand out for their low cost and high efficiency in metal adsorption due to their physical and chemical properties. Firstly, the in-situ parameters of the artisanal mining effluent were characterized, obtaining an initial pH of 2.17, characteristic of a very acidic industrial effluent, with concentrations of copper of 532,900 mg/L and iron of 989,700 mg/L. Then, three treatments were carried out with doses of 10, 15 and 20g of Zuro de Zea Mays and Musa Paradisiaca peel and their respective repetitions. It was possible to identify that the optimal contact time for the removal of Fe and Cu was 6 hours, showing the best results in all treatments. For copper, concentrations of 434.9 mg/L, 366.086 mg/L and 164.163 mg/L were obtained, corresponding to 18.39%, 31.30% and 69.19% removal respectively. In the case of iron, the removal percentages were 42.16%, 63.26% and 78.21%, which also represents significant removals. It is concluded that these results suggest the viability of using complementary treatments to reduce the concentration of metals in industrial effluents from artisanal mining to achieve better results and make them an economically attractive proposal due to their accessibility.

In the current investigation, the objective was to determine the level of efficiency of the fungus "suillus luteus" in the removal of As, Cd, B and Li in acid mine drainage from a mining environmental liability located in Hualgayoc. The means applied in the remediation have the Regional Water Laboratory and the UPN, turning the "suillus luteus" fungus into an economical and effective alternative. To begin the mine drainage, it is typified through a total metal analysis of the sample point (PM) prior to treatment, reaching initial concentrations for the PM of 0.168 mg/L of As; 0.230 mg/L of Cd; 0.503 mg/L of B and 0.119 mg/L of Li, obtaining a pH of 2.42. Applying the experimental design for the treatment of mine drainage, doses of 10, 20 and 30g of biomass of the fungus and contact times of 1, 2 and 3h were added, attributing the nine treatments to the mine drainage sample according to the test, achieving optimal remediation results through a dosage of 30g of fungus and 3h of contact time. After the treatment with biomass of the fungus, it was possible to remove As in 30.36% with 20g and 1 h, Cd in 61.21% with 30g and 3h, B in 87.07% with 20g and 3h and Li in 90.76% with 10g and 1h and increase the pH until reaching a value of 5.36, deriving it as a complementary and optional treatment to deal with environmental conflicts due to acid effluents.

The objective of the research was to determine the influence of the proposal of an MRP system on the productivity of a manufacturing company, Trujillo 2024. The research was applied, with a quantitative approach and propositional design. A diagnosis of the current productivity situation in thinner manufacturing was made, showing a level of 9.54 liters per hour, being below the sector standard, set at 10 liters per hour. This generated a total loss of S/ 65,963.50 during the year 2023 attributed to 6 root causes. A proposal for a Master Production Plan (MPS), Material Requirements Planning (MRP) and Demand Planning was developed, managing to reduce losses and obtaining an economic benefit of S/ 38,559.50, improving its operational efficiency. The economic evaluation of the proposal obtained a NPV of S/ 53,574.28, an IRR of 78.7%, a payback period of 1.9 years and a Benefit/Cost of 1.13, confirming the viability and economic profitability of the proposal, concluding that the MRP system proposal significantly influenced the improvement of productivity in the manufacture of thinners, increasing production from 9.54 liters per hour to 10.42 liters per hour
