Item Avance de la digitalización en plantas pesqueras(2022-11-01) Zanfrillo, Alicia; Morettini, Mariano; Bianchi Silvestre, GuillerminaLa transformación digital tiene en sus fundamentos un cambio cultural, manifiesto en la redefinición de las prácticas para la innovación y mejora de procesos y productos, llevando a la paulatina integración de las tecnologías existentes hacia el interior de las organizaciones y en su cadena de valor. Las empresas incorporan las tecnologías habilitadoras (internet de las cosas, robótica, fabricación aditiva, cloud computing, etc.) en sus procesos de gestión y de elaboración, brindando agregado de valor a través de la reducción de tiempos y costos de procesamiento y en la mejor interacción con clientes y proveedores a través de canales de venta y atención online. Los estudios sobre adopción de tecnologías habilitadoras y el grado de preparación (madurez digital) de las empresas para aprovecharlas se centra principalmente en nuestro país en las empresas manufactureras con escasez de información sobre la situación en otros sectores de actividad económica. La medición del grado de preparación de las empresas para afrontar los retos de la transformación digital se realiza a través de diferentes herramientas, una de ellas, diseñada en el país, es el Autodiagnóstico de Madurez Digital.Item II Jornadas de Ciencia y Tecnología : II Encuentro de investigadores en formación(2022-11-17) Mar del Plata UTN, FR; ; Scholtus, Fernando; Lupín, Beatriz; Machado Susseret, Néstor; Maggiore, Marina; Ortiz Miranda, Sebastián; Rodríguez, Yamila; Zanfrillo, Alicia InésEl presente volumen comprende las contribuciones presentadas en las II Jornadas de Ciencia y Tecnología y II Encuentro de Investigadores en formación realizadas en la Facultad Regional Mar del Plata de la Universidad Tecnológica Nacional el 17 de noviembre de 2022. Estas contribuciones son producto de la labor desarrollada en los proyectos de investigación y se inscriben en el objetivo propuesto en la edición anterior de las Jornadas respecto de construir un espacio de difusión para los aportes teóricos y empíricos de los investigadores, en formación y formados, y de las cátedras, ante los desafíos de la comunidad local y regional. Los trabajos expuestos referidos al sector naval, pesquero-acuícola y ambiental se proponen contribuir al bienestar de la comunidad, en un recorrido que comprende dos conferencias magistrales de investigadores pertenecientes a Facultades Regionales que dictan carreras homónimas a las nuestras y trece trabajos cuya autoría corresponde a investigadores de la sede que comparten como eje común en sus estudios, la provisión de soluciones tecnológicas ante los desafíos sociales, económicos, culturales y ambientales del territorio donde se asientan estas producciones.

Methodology: The research was based on a qualitative methodology, of a descriptive type with agile methodologies for the adaptation and implementation of the technological solution and techniques of documentary analysis and direct observation for the knowledge of the existing computer systems and the tests of the application carried out. Results: Deployment of the technological solution with tests on land by owners and captains of fishing vessels. Validation of the operation of the mobile application with respect to its basic functionalities. Acceptance by users of the use of digital technologies for the recording of data by trip and spear during the capture of the target species with discrimination of the added incidental species. Research limitations: The limitations of the work are found in the scope of the tests that at the end of the project and given the conditions of the software were carried out on land. Originality: For the main Argentine fishing port in the city of Mar del Plata, the first use of a technological solution was made to facilitate the registration of extractive fishing. Keywords: open innovation; mobile app; agile methodologies; fishing sector; southeastern Buenos Aires; capture.Item Tecnología aplicada a la bioconversión de residuos sólidos de la industria pesquera.(2022-07-15) Zanfrillo, Alicia Inés; Maggiore, Marina; Campins, Macarena; Rampi, Mariana; Darago, AdriánPurpose: Design a circular and intelligent process for the use of waste from the fishing industry in the city of Mar del Plata (Argentine Republic) through the cultivation of mushrooms. Methodology: An experimental quantitative methodology is adopted through the cultivation of oyster mushroom (Pleutorus sp) and reishi (Ganoderma lucidum) inoculate using a substrate made up of a proportion of anchovy (Engraulis anchoita) waste with a high content of sodium chloride. and plant residue (rich in lignin and cellulose). Results: In the experimental study, results were obtained on the selection, conditioning and composition of the inputs for the design of the fungal production process. In the incorporation of inputs, the secondary inoculate of oyster mushrooms (Pleutorus sp) and reishi (Ganoderma lucidum) and the substrate (pine straw and anchovy waste) were used. The composition of the substrate was determined to be 70% pine straw as a source of lignin and cellulose and 30% anchovy waste. The conditioning of the substrate for the development of the crop required a humidification of the vegetable residues, a drying of the animal waste and the subsequent sterilization process. The survival of the mycelium in a substrate with animal waste with a high salt content is similar for the two species of fungi considered, therefore, for the crop to prosper, humidity values below 49% are required. Genuine traceability of the inputs (anchovy and mushroom waste) and of the development process -mycelium- until obtaining, a posteriori, the mushrooms. Research limitations: The experiment is limited to salted products of the species Engraulis anchoita and the quality of the products obtained after the incubation and fruiting processes, as well as the reuse of the substrate, is still under study. Originality: The use of waste from the canning fishing industry, with a high content of sodium chloride, through the fungal kingdom, to reduce the negative environmental impact.Item Morphological changes, peptidase activity, and effects of exogenous enzymes in the early ontogeny of Nile tilapia, Oreochromis niloticus.(2022-07-14) del Valle, Juana Cristina; Zanazzi, Aldo Nahuel; Rodriguez, Yamila Eliana; Haran, Nora Selma; Laitano, María Victoria; Mallo, Juan Carlos; Fernández‐Gimenez, Analía VerónicaDuring the early ontogeny, the transition from endogenous (yolk protein) to exogenous feeding (artificial diets) represents a critical period linked to the undifferentiated digestive system, with low digestibility of food protein. The objectives of this work were to characterize the morphology of the early Nile tilapia (Oreochromis niloticus) developmental stages and determine the activity of alkaline and acid peptidase enzymes during the ontogenesis from hatching to 20 days post-hatching (DPH). Also, the in vitro effect that exogenous enzymes from Argentine red shrimp (Pleoticus muelleri) waste have on the alkaline peptidases of larvae from 6 to 20 DPH (which correspond to the age at which fish eat exogenous food) was studied. Both acid and alkaline peptidase activities varied throughout early ontogeny development (from 0.1 to 1, and from 0.1 to 7.1 UE mg protein− 1, respectively). The patterns of both enzyme activity variation would be related with changes in endogenous, mixed and exogenous feeding. Our studies show that the additions of the enzyme extract of shrimp have a synergistic effect (from 3 to 6 times) on endogenous in vitro activity. Moreover, the zymogram analysis demonstrates that the bands corresponding to the activity of each species (tilapia and red shrimp) remain active when they are mixed. The increase in peptidase digestive capacity by addition of exogenous enzymes would maximize the assimilation of nutrients from artificial food during early development
