Abstract

The black sticky tapai/ Tapai ketan hitam in Batusangkar, made by fermentating black sticky rice and yeast. The fermentation of black sticky tapai take several days to produce a sweet taste. This process may some assumption that the sweetness in black sticky tapai comes from alcohol as a result of sticky rice fermentation reaction with yeast. As the time of fermentation increases alcohol content, this raises doubt the halalness of black sticky tapai, because based on MUI Fatwa Number.4 in 2003 says the drinks containing ethanol (C2H5OH) more than one persen are categorized haram. Because of that, need some research to see the impact of duration fermentation to alcohol concentration on black sticky tapai in Batusangkar city. The reaserch data was obtained by distillation from various duration of fermentation. The result data were analyzed by product moment correlation test (? = 5%). Base on the research conducted, obtained information that in black sticky tapai contain etanol which has increased alcohol concentration along with the increase of fermentation duration. However, it becomes contradictory with the result of analysis where Y = 3,635 - 15,54 X, t arithmetic ? t table, that is 0,16 ? 3,18. This conclusions that there is no relationship between duration of fermentation with alcohol concentration.

Abstract

Amendment and development of education in Indonesia today requires various elements of education to participate in improving the quality of graduates to be able to compete in the global world. Indonesia was ranked 34th away from Singapore, Malaysia, Japan and Korea in the 20th position. This is because the educational institutions in Indonesia have not been able to produce graduates who are capable, superior, competeable with others. The educational tertiary education institution (LPTK) as one of the teacher producing institution has not been able to create prospective teacher who are ready to teach. The characteristic of the lecture process that is stated in Permenristek Dikti no. 44 of 2015 is interactive, holistic, integrative, scientific, contextual, thematic, effective, collaborative and student-centered. One way to realize this is to develop teaching materials that are used in applicable and communicative lectures. Based on the phenomenon, the researchers conducted research and development. In this study,  researchers produce the elementary statistical teaching materials using the Minitab application by following Borg & Gall's research and development steps, namely (1) Carrying out information gathering (2) Designing (3) Develop the initial product form (4) Conduct pilot field trials. If can be concluded that the research on the development of statistical teaching materials that have produced valid products and can be used in lectures to develop student creativity. This development research should be continued in the next stage, namely the product effectiveness stage.

Abstract

Technology that is developing at this paper are believed can help teachers to create learning media. For example, is the use of technology in m-learning's virtual learning media which can be applied to android smartphones. Learning that is currently happening is only conventional and the use of instructional media by teachers has not developed according to technological progress and the use of these technologies has not been applied in learning. Therefore, research is carried out which aims to produce an android-based biology learning module about the material of the regulatory system for SMA / MA students who are valid and practice. This research development using three of the four stages of the development model of 4-D Models, which consist of defining phases, design phases, develop phases, distribution phases (disseminate). The data of this study are primary data obtained from the validation sheet and practicality test questionnaire, then analyzed by descriptive analysis. This research produces a product in the form of a valid and practical biology-based learning module. Based on the validator's assessment, the android-based biology learning module is categorized as very valid (82.84). Based on the assessment of android-based biology subject teachers in the very practical category, the average results of 87.92 were obtained and based on the assessment of students the biology learning module was categorized as very practical and obtained an average value of 86.6. The Android-based biology learning module that the researchers developed is feasible to use in the learning process.

Abstract

This study aims to produce a learning media design in the form of multimedia mathematics based inquiry learning for fourth grade students of elementary school. This type of research is development research using the 4D model. This study looks at how the procedures for developing multimedia learning mathematics learning are viewed from the form of flowcharts, Storyboarding, and multimedia programming results of mathematics learning. Then validation was seen from 3 aspects including the content aspect, constructive aspects and language aspects. From the results of the research that has been carried out obtained the average validation of 84.5 with a very valid category. Based on the research data that has been obtained, it can be concluded that the multimedia learning mathematics based inquiry has been valit and can be used in learning in elementary school.
