Behind the success of successful online teaching and learning, there must be careful preparation in creating or building the system. Some complaints that are around us are that some students have difficulty in online-based mathematics learning. Some of them have difficulty signaling due to cloudy or rainy weather, not having money to buy internet quota, boredom during the teaching, and learning process, and difficulty understanding the material in online learning. Although there are examples that have been explained by the teacher, they still do not understand what their teacher teaches them. The teacher had already made learning materials using instructional video media, but it was still not enough for students to understand the polynomial material taught by the teacher, and according to the teacher the main problem was that the students' ability to memorize formulas was still lacking.

Dating is something that is very close to our daily life. Dating in this millennial era, everyone may also be familiar with the component known as the relationship. Dating relationships are especially important for younger adults. Millennials want positional fashion as an extraordinary courtship. Along with the times and technology, millennial fashion relationships are becoming more and more excessive. It depends on the character of the individual with a view to comparing their courtship relationship with certainty or negatively. The millennial generation is often referred to as a very open technology, likes practicality and dares to take risks. In terms of love life, it is now not much different. In younger people, courtship is seen as a method of gaining recognition. For example, the idea that a person is considered a person if he or she already has a partner, daring to have a relationship is considered manly or having a female friend who is handsome or beautiful is considered an achievement.

Snack bars are known to meet consumers' needs for nutrition, taste and practicality. There needs to be additional raw materials that are high in nutrients so that the products produced are beneficial to the body and also provide health effects. One plant that is high in nutrients and also provides benefits for the body is the Moringa plant. Moringa is known to contain more than 90 types of nutrients, namely in the form of essential vitamins, minerals, amino acids, anti-aging and anti-inflammatory. Our body needs antioxidants that can help protect the body from free radical attacks, considering that very many free radicals come from outside the body, namely in the form of foods that contain preservatives, dyes, fats, pesticides, pollution, dust and ultraviolet radicals. The process of making snack bars, roasting temperature and the proportion of flour are among those that can affect the characteristics and maturity levels of the resulting product. This study was conducted to determine the effect of temperature and flour formulations on sensory, texture profiles and antioxidants. The study used RALf (complete random design of factorial) 2 factors. From the results of this study obtained the results of roasting temperature affecting the profile value of the texture parameters hardness / hardness, gummieness / stickiness, chewieness / chewing power but has no effect on the results of antioxidant activity and hedonic sensory. The formulation of cornstarch and moringa flour on the results of the texture profile affects the parameters of resielience / snack bars. Formulation of corn flour snack bars and Moringa flour has a real effect on the antioxidant activity value of corn flour snack bars and moringa flour. Where the addition of moringa as much as 10% with a temperature of 120oC has a value of %ibhibisi as much as 87.66 and flour formulations also have a real effect on all hedonic sensory parameters, namely aroma, color,  taste and overall.

Main Objective: The main objective of this study is to empower designers to collaborate with researchers in other disciplines — especially in the social sciences — by articulating a design inquiry model that can be implemented in a master's program in design. Background problems: Modern research problems are complex and design needs to be better integrated with the social sciences and play an equal role in addressing them. A final master's degree in design prepares students for this integration, but design activity should be evidence-based rather than viewed retrospectively as a form of research without change. We need to adapt to ultimately contribute to research. Novelty: There are main criteria for design-based inventions in this study, including value, relevance, novelty, focus, transferability, and practicality. When these criteria are met, investigations can operate within the social sciences, or they can be leveraged and serve as the discovery phase in evidence-based inquiry. Research Method: This study presents design-based discovery, a design inquiry model that places design in the theory development cycle as theory building, not theory testing. This research, therefore, uses a design inquiry model approach, (invention-based design) in other disciplines by articulating a design inquiry model that can be implemented in a master's program in design to be complementary and compatible with social science research. Finding/Result: A proposed design inquiry model with design exploration serving as the research discovery phase guiding the design activity to make specific contributions to areas of social science that are outside of design. It involves a careful process with six investigative components, all ultimately connecting the knowledge base beyond design to design exploration. Conclusion: This study proposes six main criteria for design-based inventions: value, relevance, novelty, focus, transferability, and practicality. In the model proposed in this study, the six investigative components are described and supported with examples. Notably, the investigative component includes a standardized format for research questions, as well as the derivation of design principles from processes that involve exploration rather than one that generates solutions. This model can easily be adopted in other master programs with the necessary resources. In addition, this model, if placed in design activities in evidence-based research practices, can become wider. There is no claim that a designer's self-reflection equates to a strictly social science method so design researchers must continue to study design and build on their knowledge of the discipline.
