Social implications of biomass-based energy generation in the technical university of Manabí, Ecuador

2020-02-21T19:03:04+00:00

Biomass as an energy source will play a fundamental role in the coming years. The versatility of biomass-based generation systems makes them attractive projects at any scale. At the Technical University of Manabí, large quantities of organic and forest residues are generated, which can be used to generate energy. A survey was applied to determine the level of knowledge of the university community on issues related to the energy use of biomass and solid waste management. The results show that there is a knowledge gap in the community and it will be necessary, if such a system is implemented, to train all those involved in the generation, handling and disposal of solid waste to strengthen the proposal.

Cocoa drying system using ancestral sliding

2020-02-21T19:03:02+00:00

The decrease in the application of ancestral practices such as the drying of cocoa in traditional slides is a problem that affects small grain producers in terms of the price of the product, which is mostly sold in slime. It is intended to design an ancestral slide for cocoa drying so that ancestral knowledge of cocoa drying is recovered by promoting a fair price for cocoa that benefited for small producers. An experimental field methodology was applied. Results were obtained in 24 hours of drying light 7% humidity at an average temperature of 34º C, a parameter that allows preserving the quality of the grain during storage and without risk of deterioration due to the appearance of fungi. A solar-powered dryer was traditionally called slides used by small producers of cocoa in the province, where they can use materials from their environment and obtaining a dryer with a capacity, drying hours and percentage of humidity similar to the use of a dryer with conventional energy, without paying for the grain drying service in an industrial dryer.

Consumption, nutrient digestibility and nitrogen retention in pe goats received ransum with various levels of gamal (gliricidiasepium) balance versus concentrate

The research aims to determine the consumption, nutrient digestibility and nitrogen retention in PE goats, which has been carried out in Sidemen Village, Karangasem, Bali and in the Lab. Animal Nutrition and Feed at Udayana University. The research design used was the Latin Square Design (LSD) with treatment consisting of (P1) 55% field grass with 45% concentrate; (P2) 55% field grass with 15% Gamal and 30% concentrate; (P3) 55% field grass with 30% Gamal and 15% concentrate; (P4) 55% field grass with 45% Gamal. Research variables include consumption, nutrient digestibility and nitrogen retention. The results showed the consumption of dry matter and crude protein between treatments was not significantly different (P> 0.05). Crude fiber consumption of P4 treatment was significantly (P <0.05) higher than P1, but P4 was not significant (P> 0.05) higher than P2 and P3. The dry matter digestibility coefficient and crude fiber digestibility coefficient between treatments were statistically significantly different (P> 0.05). The digestibility coefficient of organic matter, crude protein digestion coefficient and nitrogen retention in the P1 treatment were not significantly (P> 0.05) higher than P2, but P1 was significantly (P <0.05) higher than P3 and P4.

The properties of tagua bark (brutelephas aequatoriales spruce) for producing traditional salprieta

2020-02-21T19:03:01+00:00

Manabí is a province rich in cultural traditions. Its cuisine makes it a province visited by national and foreign tourists. The salprieta is one of the delicacies that identify the province, however the tradition of making salprieta is being lost, that made with tagua that despite not being so widespread became a typical dish of the areas where the crop del Cade constituted the economic support of its inhabitants (Chone, Calceta, Junín, San Plácido, Paján and Jipijapa), because from this plant many by-products are obtained such as the cade used for the construction of roofs of houses and agricultural constructions; the tagua, for the elaboration of crafts, and the bark of this one is used for food of the cattle in the form of flour; and for the elaboration of salprieta in replacement of the corn. The research problem is centered on the loss of ancestral knowledge in the peasant communities to elaborate salprieta using an available resource such as the tagua bark, available raw material that is not used due to ignorance, whose nutritional properties are excellent, as we indicate the tables attached to the document.

Traditional knowledge using medicinal plants in Portoviejo Canton

2020-02-21T19:03:00+00:00

The problem centers on the loss of empirical knowledge of the use of medicinal plants as a source of alternative medicine. The objective of the work is to carry out a study aimed at establishing the current state of local knowledge about the use of medicinal plants in rural parishes and 1 urban one of the Portoviejo canton. The method was based on the literature review on the subject and as techniques, the population survey was used on the knowledge and importance of medicinal plants. The main results of the research included the recovery of the use of medicinal plants as an alternative medicine use. As a result, it was obtained that the inhabitants of these parishes of average age between 35-59 years, had a high impact on the applied surveys of 39.1% of the use of medicinal plants and that the lowest ignorance of the use of medicinal plants as an alternative in medicine it was obtained by people of average age between 60 and over, but this is due to memory loss. It is concluded that knowledge about medicinal plants is regular since their inhabitants do not maintain continuity in their use.
