Abstract
Abstract This research is motivated by the low interest in reading students towards concepts that are considered difficult because they are abstract, especially on the concept of hydrocarbons, so that the media needed can help students to understand the context with the help of simple, efficient and interesting tools. This study aims to describe the stages of making AR technology-based learning media on the concept of hydrocarbons, increasing students interest in reading, and analyzing the feasibility of the learning media. Research and development has produced products in the form of AR technology-based learning media on the concept of hydrocarbons. The stages of research are carried out by analyzing hydrocarbon concept development, design, validation, feasibility testing, and limited testing. Due diligence and limited testing are conducted to obtain feedback for improvement and assessment of learning aspects, conceptual substance, visual communication, and software engineering, as well as the feasibility of their use. In general, the test results obtained by the calculation of feasibility = 0.8-1.0 and the reading interest questionnaire indicate that students-reading interest has increased. This shows that the presentation of learning media is appropriate to be used as a learning resource for students to increase students-reading interest in learning.

Abstract
Sunnah eating practices has the element of healthy eating practices. The Sunnah which refers to the practices of the prophet Muhammad should be followed by Muslim worldwide. Nevertheless, most Muslim has the problem of overweight and obese including the Muslim in Malaysia. Less was known on Sunnah eating practices as previous studies were focusing more on Sunnah foods. To design appropriate, faith-based intervention on Sunnah eating practices, the facilitators and barriers towards it should be assessed. The aim of this study is to explore the facilitators and barriers to Sunnah eating practices among overweight middle-aged Muslim women. A total of 22 participants (age 52.45±4.68 years) in Klang Valley were recruited through purposive sampling design and were interviewed face-to-face using an in-depth semi-structured interview guide. Data collected were analysed using thematic content analysis. The major facilitators of Sunnah eating practices are health status, awareness, observe Sunnah practice and culture. Meanwhile, the major barriers are time constraints, outside foods, preferences and culture. Overall, the facilitators and barriers to Sunnah eating practices were much influenced by several factors including family, environment and education. This study provides the deeper look into what are the facilitating factors and barriers for Muslim people to implement Sunnah eating practice and insights for health professionals to design a relevent faith-based intervention.

Abstract
To meet the basic needs of life, clothing, food, and shelter is the right of every individual. Every individual has the right to have a decent life, which is clothing to cover his/her body, eating to fulfill the needs of stomach and housing as a place to shelter. However in the real condition, not every person has a good fortune, also there are not a few of people who live with shortcomings. Religion provides a solution to overcome this problem, namely by presenting the concept of charity. The concept of charity in Islam is called zakah, infaq, or sadaqah. In Christianity, it is called tithing. In Hinduism, it is called Punia. In addition to these religions, each religion has its own concept of charity, which is to spend little money or funds to be given for those in need. Charity in the technical distribution can be done individually (man to man) between donors and recipients, there is also charity which is done collectively, namely by the establishment of charitable institutions that collect funds from donors and distribute them for those in need. Along with the development of information and online technology, many charitable institutions are now using the technology. This method provides convenience not only for these institutions, but also for donors, so donors can simply use the online application to donate. However, the use of online technology in addition to providing a positive impact, there are several disadvantages, including the lack of humanity. An example is the loss of the emotional side between donors and recipients, the lack of conformity in the halal regarding to the sources of the funds, and lack of information on the distribution of funds by those charitable institutions. Seeing these conditions, it is required a model in online technology that does not exclude humanist values which are the real spirit and real implementation of charity, so the use of online technology in charitable fund collection and channeling by fundraiser institutions can be done maximally.

Abstract
In this increasingly competitive 21st century global economy, it is necessary for students to have adequate skills to cope with demands of 21st century. This quasi-experiment research aims to get an overview of how to train 21st century skills by applying inquiry-project based learning with reading infusion strategy. The participants are 121 students, randomly picked from 288 students at one of the senior high schools in West Bandung district. The development of 21st century skills was measured using rubric adopted and adapted from Boss. The analysis used standards developed by Lati, which have been tested through inter-rater reliability technique with reliability value 0.67. The result shows that in experiment class, collaboration and communication skills can increase to “good” level. However, critical and creative thinking skills are still in “fair” level. While in control class, collaboration and communication skills can increase to “fair” level. But critical and creative thinking skills are declining to “very poor” level. Based on the results, it appears that inquiry project-based learning with reading infusion can help improving the development of certain 21st century skills. Lazy-to-read habit that students do still becomes an obstacle, therefore more appropriate ways are still needed in developing 21st century skills.

Abstract
Abstract. A virtual laboratory is an approach that has been widely used in biology learning but remains a challenge for countries that are still experiencing obstacles in technology. Biology has some abstract concepts which are difficult to be understood by simple explanation, or even difficult to be practiced in a traditional laboratory. The challenges of virtual labs in the biology needs to be analyzed to capture what the characteristic of biology topics which are generally designed with virtual labs and what the impact of virtual labs to students conceptual understanding and their laboratory skills. To track those queries, the systematic review was carried out on research articles published in academical journals within 2010 to 2018. A total of 23 empirical articles were analyzed. Cell or molecular biology and introduction biology are the most widely topics used in the virtual labs. While, understanding the biological concepts is the most studied variable, and virtual labs worked significantly on it. Some studies examined students affective and skills, and the virtual labs are also effective. However, only a few studies examine the learning process. Most biology virtual labs are developed by Adobe Flash Player application with 3D animation. This article suggests further research to develop a biology virtual lab that is more inquiry-based, and measures students understanding of abstract concepts, and science process skills that have not been widely studied.

Abstract
The independent film industry, has been taking the prime role in promoting controversial films that encourage the communities to think with their own notion of national identity in Indonesia, since the post-reformation era. The aim of this paper is to utilized the Benedict Anderson (2006) imagined community concept, in analysing the notion of national identity, within the dimensions of collective memory (historical memory and horizontal comradeship) and geographical boundaries. The analysis will cross linking into the various identity lenses and the discourse of the Pancasila. Analysis of four independent films and 27 interviews with the industry stakeholders shared the multiple interpretations of national identity: (1) demonstrated the society-s memory on issues surrounding fundamentalism, poverty, patriarchy and gender roles, racism and discrimination, society judgement and tolerance, and patriotism in the society; and (2) the alignment of film directors in the formulation of national identity within the concept of Pancasila through the present of nation-s symbols such as national song, flag, identity card, uniform, and national language. However, the film community also tries to inform that the issues arouse in the society which mostly relates to the values of Pancasila, not something that does not need to be given attention both by the society and government.

Abstract
This study aimed to find out an overview of students algebraic thinking abilities viewed by auditory learning styles in one of the junior high schools in Bandung. This research is motivated by the results of studies that show varying ability (high, medium, and low) of junior high school algebra, so it is necessary to know the cause, and one of the causes is learning style. The subjects in this study were three students with auditory learning style. This research used a qualitative method. The data was collected using: learning style questionnaire, essay test, interview, and documentation. The results show that students who have auditory learning styles tend to answer with explanations in the form of sentences so that they can clarify what they mean or what they understand. Students who have auditory learning styles are able to fulfill indicators in algebraic thinking skills: conceptually based on computational strategies, manipulating numbers and symbols using algebraic rules, and expressing generalizations of patterns and rules in real-world contexts. Based on this research, the researcher suggested that the students can be facilitated with appropriate learning methods or models to contribute well to their algebraic thinking abilities.

Abstract
In the Education curriculum, mathematics is a compulsory subject that must be learned by students since elementary school, because of its usefulness for students daily lives. But many obstacles experienced by students in learning mathematics, one of which is mathematical anxiety. So, this study aims to explain how students- mathematical anxiety is viewed from gender factors and its implications. The subjects of this study were 10 students of 5 graders, an elementary school in Sumedang. Case study method is used to understand and analyze students- mathematics anxiety. The results of the study were obtained from data collected through questionnaires, interviews and field notes when the mathematics learning process took place which was then analyzed descriptively. During the study it was observed that mathematical anxiety of female students tended to be higher when compared to male students. This mathematics anxiety will increase as students face exams. The implication of students with high levels of mathematics anxiety tends to be distracted by their concentration in learning mathematical material. This then has an impact on the acquisition of student learning outcomes that are less than optimal. Thus the lower the level of students- mathematical anxiety, the higher the mastery of students mathematical concepts.

Abstract
Mostly, logic gates were communicated by permanent exhibits in museums. Our logic gate board game was created to be an alternative way for communicating contents and developing children-s self-motivation in the informal context. Three logic gates—AND-gate, OR-gate, and NOT-gate—were embedded in the mechanism of the board game. With the game interaction, the main goal is to encourage the children to create their own strategies to complete a mission by using conditions (gates). A fairy tale was used to engage the children to play the game. We investigated children-s understanding and intrinsic motivation through playing the board game in the informal context. The participants of this study were 21 primary children who participated in a one-day camp at the science museum. To examine the children-s motivation, the data was collected by an intrinsic motivation survey, a behavior observation checklist, and an interview, while a conceptual knowledge test, and the interview were utilized to gather the children-s understanding. All data were collected and analyzed by mixed methods. The participants were introduced the rules and the context of the game before playing the game. During the game play, the children-s interaction with friends and the game were observed. The children were assessed by completing the test and the survey consecutively. Then, a debriefing session was held at the end of the assessment. Some voluntary children were interviewed to investigate both their understanding and motivation. The results of the survey show the success in promoting the children-s intrinsic motivation, e.g. perceived learning, engagement, immersion, challenge, and skills. Particularly, the engagement factor has the highest frequency on the survey. Corresponding to the interview result, the engagement, enjoyment, concentration, and interest were the most mentioned. From the observation, it seems that the children were completely focused throughout the game. Besides, in the understanding aspect, Most students could develop their understanding of the logic gates through the board game. Supported by the interview result, the children mentioned the strategy they used to complete the mission which required their logical thinking. However, it seems that the children still could not apply knowledge gained from the board game to the real-life problem. In contrast to the enjoyment in the game session, they showed uncomfortable faces when they were asking to do the conceptual knowledge test since it did not normally happen in the informal context. Importantly, the board game could be used to promote children-s understanding and motivation of the logic gates in the informal setting.

Abstract
Reasoning is one of the abilities needed in solving mathematical problems. Based on Lithner perspective, reasoning divided into imitative reasoning and creative reasoning. There are three indicators for each reasoning, that are plausibility, mathematical foundation, novelty for creative reasoning aspect and imitation for imitative reasoning aspect. The aim of this research is to analyze the qualitative effect of problem-based learning model toward students mathematical imitative and creative reasoning. In order to do so, we used descriptive qualitative methods by taking eighth-grade students (around thirteen to fourteen years old) in one of the Junior High School in Tasikmalaya. We used the data from a written test, observation and interviews. The results revealed that problem-based learning model suitable for students who have dominantly mathematical creative reasoning abilities. The characteristics of students who have dominantly mathematical imitative reasoning abilities prefer to be told rather than finding out. Based on the results, we conclude that each student has a different learning style according to his abilities.

Abstract
Education must be able to connect technology advances, the industry and learning in the classroom. These include advances in the fields of chemistry and chemical education to teach students to be able to contribute to solving problems and sustainable development in the future. Chemical education is considered to have a central role in education for sustainable development. For this reason, we need a concept in a chemical education curriculum that can support sustainability. System thinking in chemistry education is relevant to sustainability. Through system thinking, students are challenged to holistically understand the scientific process. This study aims to review the literature on systems thinking and sustainability in chemical education. A total of 9 articles from reputed international journals were the main sources for review. The results of the literature study conducted were the implementation of the system thinking in a chemical education curriculum was a potential thing. The relationship between sustainability and systems thinking were discussed

Abstract
This article exposes how STEM-based learning is applied in science class to give students meaningful learning experience in the topic of Pascal Law. This study is motivated by the demand of 21st century skill which expect people to have 4C skills; critical thinking, creativity, collaboration, and communication. In this study, STEM-based learning is conducted at a private secondary school located in Bandung with 28 students of grade 8 as the subjects. Students are provided a problem related to the application of Pascal Law namely hydraulic bridge. They are challenged to design their own hydraulic bridge which can be lifted with maximum angle but in minimum time. A descriptive study is taken where all the data is obtained through direct observation and students- interview. Based on cognitive test, there is difference on pre-test and post-test score that resulting in the number of gain. Based on direct observation, none of students just sitting on their seat without activities and all are on collaboration to reach their goal. Students- interview indicates they enjoy learning process as it is their first experience accomplishing a project and it makes them more understand the concept through the real application. Overall of the study, STEM-based learning through hydraulic bridge project stimulates students to be able to think critically, to be creative, to collaborate, and to communicate.

Abstract
The objective of this study was to observe the effect of Connecting, Organizing, Reflecting, and Extending (CORE) instruction model by work card toward students- mathematical problem-solving skill in Junior High School 1 Klari. The research method was quasi-experiment using non-equivalent post-test control design. All classes in seventh grade become the population. Two-stage sampling technique, namely purposive sampling and cluster random sampling technique, was used to select VII-A as the experimental class who treated with the CORE instruction model by work card and VII-B as the control class who treated with direct instruction model. Students- mathematical problem-solving skill was measured by the test which created based on problem-solving skill indicators. Based on hypothetical testing using independent sample t-test with a significance value of 0.05, the result has shown that there was a significant difference between the experimental and control class. There was t count = 4.6932 > t table = 1.667, then H0 was rejected. This result was indicated that the average of the students- problem-solving skill who using CORE instruction model by work card higher than the average of the students- problem-solving skill who using conventional instruction model. Therefore, it can be concluded that the CORE instruction model by work card affected to students- mathematical problem-solving skill in Junior High School 1 Klari.

Abstract
Abstract. Dynamic assessments (DA) had been widely used in language and mathematics learning, but its use in science learning is still limited. One difficulty faced by students in science learning is the sheer number of abstract concepts. This literature review was aimed to find out the prospect of DA in science learning to improve students- understanding of abstract scientific concepts. This study analyzed various learning topics used with DA, the types of DA instruments, and procedures to train students- conceptual understanding. The PRISMA was used as the research method. The results showed the DA has been used in learning ecology, biology, atmosphere and water, evolution, and classification, photosynthesis, and weather and climate. It showed DA can improve students- conceptual understanding. Implementing DA in the learning process can be done by providing additional explanations or training to students. The types of instruments for DA were varied, such as tests, questionnaires, and interviews with semi-structural forms. We recommend the usage of DA to improve student understanding regarding abstract science concepts, especially biology.
