Objective: The objective of this study was to process coffee leaves to obtain a product with greater added value.

Theoretical Framework: In this study, the processing of coffee leaves was like the processing of yerba mate to produce chimarrão. The enzyme inactivation technique is applied prior to drying, the leaves are exposed to a flame for a short period. The yellowish-green color is more uniform among the group of inactivated leaves and indicates good efficiency at this stage.

Method: The coffee leaves were divided into two groups for enzymatic inactivation in times of 60 seconds and 120 seconds. The leaves were dehydrated at a temperature of 60ºC for four hours. After drying, the material was ground, and colorimetric analysis was carried out (12 tasters participated in the sensory analysis).

Results and Discussion: Statistical analysis demonstrated that there was no significant difference in the preference of the product served, with or without sugar. The importance of an integrated approach in the processing of coffee leaves is highlighted, considering the physical-chemical, sensorial aspects and including pharmacological effects beneficial to health

Research Implications: The growing human search for a more balanced and healthy diet promotes the addition of functional and medicinal beverages to diet, creating a challenge.

Originality/Value: The importance of an integrated approach in the processing of coffee leaves is highlighted, considering the physical-chemical, sensorial aspects and including pharmacological effects beneficial to health.

AbstractMicrolearning is becoming more popular in education due to its convenience, flexibility, and effectiveness. The popularity emerges from the use of chunking of materials in short and understandable components that makes it easier for learners to attain the information at their convenience. Preferably, learning materials are microlearning-designed. However, since not many teachers are well-informed about microlearning, the existing learning materials may not be microlearning-based designed. Studies focusing on this issue are relatively limited. This study aims to analyze whether English learning materials at senior high school are designed based on microlearning principles. Twenty four English learning materials covering various types of materials including textbook, e-module, webpage, as well as, pre-recorded teaching and YouTube videos designed for grade X, XI, and XII collected from three senior high schools in Jakarta were analyzed using microlearning framework. The findings of this study show that the existing learning materials do not conform to microlearning principles. The results of this study reveals the needs to design microlearning-based materials, break the lesson units into micro contents, and produce microlearning object materials for English lessons in high schools.

В статье характеризуется одна из наименее освещенных в научной литературе сфер исполнительства на фаготе – эстрадно-джазовое музицирование. Автор рассматривает творчество ведущих представителей джазового исполнительского искусства на инструменте, определяет основные тенденции в этой сфере современной концертной практике, исследует теоретико-методологические основы обучения данному виду музицирования на инструменте. В заключении статьи рассматривается вопрос об открытии классов эстрадно-джазового исполнительства на фаготе. Автор приходит к выводу, что в случае обучения искусству джазового исполнительства в его «чистом» виде, подобная мера в фаготовой педагогике не нужна, поскольку востребованность таких исполнителей носит ограниченный характер. Автор полагает, что современных средств самостоятельной профессиональной подготовки вполне достаточно для того, чтобы фаготист, имеющий предрасположенность к джазовому исполнительству самостоятельно достиг в нем вершин мастерства. Однако, учитывая стилевые тенденции в современном сольном, ансамблевом и оркестровом академическом исполнительстве на фаготе, автор считает очень важным обучение в классах фагота некоторым элементам эстрадно-джазового искусства, таким как, например, типичные «эстрадные» штрихи, основы искусства свинга и т.д.
The article characterizes one of the least illuminated in the scientific literature spheres of performing on the bassoon – pop-jazz music. The author examines the work of the leading representatives of jazz performing art on the instrument, determines the main trends in this area of modern concert practice, explores the theoretical and methodological foundations of teaching this type of music playing on the instrument. In conclusion, the article deals with the question of opening classes of pop-jazz performance on the bassoon. The author comes to the conclusion that in the case of teaching the art of jazz performance in its "pure" form, such a measure in the bassoon pedagogy is not necessary, since the demand for such performers is limited. The author believes that modern means of self-training is enough for a bassist who has a predisposition to jazz performance independently reached the heights of skill in it. However, taking into account the style trends in modern solo, ensemble and orchestra academic performance on the bassoon, the author considers it very important to teach some elements of pop-jazz art in the bassoon classes, such as, for example, typical "pop" strokes, the basics of swing art, etc.
