  El objetivo del presente estudio fue revisar fuentes documentales sobre el contenido lignocelulósico de los residuos agrícolas del cultivo de arroz, plátano, maíz, caña de azúcar, y piña para la obtención de nanocristales de celulosa. La investigación con enfoque cualitativo- documental descriptivo recopiló datos del objeto de estudio para su análisis y evaluación. Se analizaron diversos planteamientos teóricos, procedimentales y metodológicos para la obtención de nanocristales de celulosa; se identificó el tipo de residuo generado por cada cultivo en estudio, de los cuales se describió el contenido lignocelulósico que poseen con el propósito de establecer que por su composición se constituyen en un material potencial para la obtención de nanocelulosa; luego se analizaron los métodos empleados en la obtención de nanocristales de celulosa. Con base a los documentos revisados se concluye que los diferentes residuos agrícolas poseen un contenido celulósico relevante (28-100%), por tanto, convirtiéndolos en materiales aptos para ser aprovechados para obtener nanocristales de celulosa.   Palabra clave: Hidrólisis ácida, métodos de extracción, residuos lignocelulósicos.   Abstract The objective of this study was to review documentary sources on the lignocellulosic content of agricultural residues from the cultivation of rice, banana, corn, sugar cane, and pineapple to obtain cellulose nanocrystals. Research with a qualitative - documentary and descriptive approach, collected data from the object of study for analysis and evaluation. Various theoretical, procedural, and methodological approaches for obtaining cellulose nanocrystals were analyzed; the type of residue generated by each culture under study was identified, of which the lignocellulosic content that they possess was described, In order to establish that their composition constitutes a potential material for obtaining nanocellulose, the methods used in obtaining cellulose nanocrystals were then analyzed. Based on the revised documents, it is concluded that the different agricultural residues have a relevant cellulosic content (28-100%), therefore, converting them into materials suitable to be used to obtain cellulose nanocrystals.  Keywords: Acid hydrolysis, extraction methods, lignocellulosic residues.

This research was conducted to find out how big the interest of tourists who come to visit wajik stalls and sugar cane juice sweet so that in know whether the two places are worthy made in culinary branding in the city of Berastagi tourism. The method used in this research is qualitative method with descriptive research type which explain the actual condition that happened in the field with data collection technique through observation, interview and documentation. Based on the results of the research can be in the know that in general the interest of visitors to enjoy the menu at the stall wajik peceren better in comparison the interest of visitors in sweet sugar cane stalls. The price offered in these two stalls is very relative and classified as not so expensive and visitors who come to stalls wajik peceren usually buy diamonds that are characteristic of the shop to be brought as by the family at home while the visitors who enjoy the menu at the sweet sugar cane where in general, visitors who come only enjoy the menu on offer, especially Berastagi sugar cane and not brought home as souvenir for the family.
