Abstract
One of the abilities of the 21st century that students must have is creativity, but this ability is not too meaningful if it is not accompanied by a good spiritual attitude (in accordance with the 2013 curriculum in Indonesia), as well as always being a concern for public schools research is rarely focused on religious-based schools (madrasah) even though the potential is no less great than public schools. So from that the aim of this study is to analyze the creativity and spiritual attitudes of students who appear in STEM-based reproductive system learning through performance assessment. The research methodology is descriptive, sample used was one of 11th grade classes in “Science” specialization in MAN 2 Tasikmalaya with 36 students as participants. Creativity here is seen from a creative person (Person), the creative process (Process), the pressure that arises (Press), and the product it produces (Product). The results of the research show that the students of madrasah (in this case MAN 2 Tasikmalaya) have different levels of creativity, both compared in terms of "person", "process", "press", and "product" no one has a level of creativity same. On average students have "emerging" category creativity. Creativity is also not directly related to students personal spiritual attitudes, however, some students who have very good spiritual attitudes tend to have creativity that is categorized as "expressing".

Abstract
STEM that an acronym for science, technology, engineering, and mathematics defined as the integration of science, technology, engineering, and mathematics into a new cross-disciplinary subject in schools. We dont deny that the concept of integrating subjects to teach science in Indonesian schools, generally is not new and has not been very successful in the past. In addition, some people consider STEM as an opportunity while others view it as having problems. However, the answer to how STEM education implementation has not been studied yet comprehensively. Therefore, STEM education-s lesson plans is very important to be designed then implemented. This work designed STEM education-s lesson plan on topics of ecosystem, used R&D approach four-D model that reduced into three stage: define, design, and develop. This work is non-implementation throughtout.

Abstract
Mathematics taught in school is known as school mathematics where the study of material has been adjusted to the needs of students. Nonetheless, Mathematics is actually indirectly known in the community. Indirectly the community has known mathematics in their daily activities such as counting, measuring and even producing products such as woven. This habit is a culture that can be associated with mathematical concepts better known as ethnomatematics. One example is the concept of the roof of the kebaya house which is a traditional house of Jakarta. The roof of the house consists of a triangle and a trapezoid. This can indirectly introduce the concept of flat wake to students. This study aims to design learning media applications with mathematical concepts that exist in several cultures in Indonesia that can be used as learning resources for mathematics. The research method used is research and development (RnD). To get a proper application, testing is done using blackbox testing. This application is expected to make ethnomatematics a basis for learning mathematics in the modern era.

Abstract
Mathematics and culture are two things seen as something that is not connected to everyday life. Whereas in teaching mathematics in school (formal), the teacher should start by exploring the knowledge of informal mathematics that has been obtained by students from the lives of the people around their homes. Environment can be a source of mathematical problems in real life. One of the environments is culture. Mathematics in culture is known as ethnomatematics. Each region certainly has its own culture, including Jakarta. Jakarta which is the capital city of Indonesia has a culture of traditional houses known as Rumah kebaya. Rumah kebaya has a special characteristic, especially on the roof which consists of a triangle and a trapezoid. The purpose of this exploratory research with ethnographic approach is to explore and explore any mathematical concepts that exist in rumah kebaya which can be used as a learning resource for mathematics as well as an effort to develop ethnomatematics as the basis for mathematics learning. Learning mathematics using ethnomatematics objects can enrich the mathematical applications that are around students and can facilitate students to understand abstract mathematics by using concrete ethnomatematics objects.

Abstract
Based on a preliminary study conducted in one of the international schools in Bandung, the implementation of STEM is only done once a semester. The perceived constraints are the unavailability of teaching materials. Science learning that is integrated with engineering design will facilitate students to be able to make product designs. STEM learning with engineering design will train students to use scientific and mathematical knowledge in making products. This will make learning more meaningful in overcoming real problems even by professional engineering workers. By using quantitative descriptive methods, showing the results of the average value of 8.25 engineering abilities, the feasibility of teaching materials in the category is very feasible and the understanding of students is 94%.

Abstract
The study in Aerodynamics has shifted from large theoretical curriculum into authentic learning experiences in response to the industry requirement. In addition, the development of computational methods has revolutionized the design cycle in aerodynamics. This work describes an integrated approach in an undergraduate Aerodynamics course using the Kolb-s Learning cycle. Experiential learning is incorporated in the class to provide more opportunities for students to understand the theoretical concept through experiencing the applications and impact of the concept in real life. The Finite Element Method (FEM) which is widely used in analyzing many engineering problems was integrated into the Aerodynamics theory and application to visualize changes of parameter in the design phase. The main learning objective of the developed learning module is to apply appropriate aerodynamics models to predict the forces on and performance of a vehicle design. The module is assessed by instructor before being applied for the students in the classroom. It is considered to be an effective method for learning when lectures and computation works are integrated in a meaningful manner. This development research is expected to be able to produce graduates who are competent in the field of design.

Abstract
Recently, Multiple-Intelligence-Based learning models have been widely used in classroom learning. Students are taught based on their multiple intelligences to have a good learning experience, but teachers must be able to recognize and map students intelligence before applying this learning model. This study aims to describe and properly map the multiple intelligence of children using biplot analysis. The research method used in this research is descriptive quantitative method. This research was conducted at Labschool Faculty of Education Science University of Muhammadiyah Jakarta (FIP UMJ) Primary School. Sample in this research is students in class 4.2. This analysis is expected to classify students based on the similarity characteristics of children, so that in one group has the same vision in problem solving. The results showed that all variables of multiple intelligences had a positive correlation with each other, but had the lowest correlation with kinesthetic intelligence. In addition, variables that have the smallest diversity are natural and visual intelligences. There are 4 groups of students that can be formed in multiple-intelligence-based learning, in which each group has different intelligences performance.

Abstract
Education is a major aspect of national development. Quality education is a component of the UNESCO Sustainable Development Goals (SDGs). One of the improvements in the aspect of quality education is the equal distribution of education through the Education for All (EFA) movement. Good infrastructure must support this motion, particularly the application of technology in teaching. Education is part of the educational equity system because most individuals are acquainted with technology, particularly smartphones. Massive Open Online Courses (MOOCs) are one of the e-learning models that evolve in a huge community and can be accessed by everyone. The EFA movement can be carried out well through MOOCs, although there are still multiple types of barriers encountered.

Abstract
Getting education and entrepreneurship is a right of all citizens, the education system when it has used a computer media and information assistance technology, with this technology all levels of society participate in advancing and developing the potential that exists in them. The development and use of information facilities is now easily accessible and used as an example, information media is used as a media news search, supporting educational activities and for online sales facilities, better known as e-commerce websites. The parameters of an E-Commerce Website generally have a standard criterion which is having an attractive feature menu, providing related and up-to-date news content, for people who are physically normal they will easily use all the websites of an e-commerce website, they can buy goods online or use the media to sell merchandise, because e-commerce media has an advantage that is easy to promote goods and services and there is no need for meetings between buyers and sellers. The problem faced today is that the e-commerce website does not have a feature intended for persons with disabilities, where using standard features available in e-commerce today will be difficult, disability has the same rights in using an information media, in this journal a website system will be developed that can be used for persons with disabilities, a website will be added with a voice feature that will be used as a material to help guide media when the website is opened. The feature does not use too many menus so that it is easy to use, the voice feature is made in a button action so that the purchase process from an e-commerce website is easier.
