ANALISA KUALITATIF DAN KUANTITATIF KANDUNGAN ALKOHOL PADA TAPAI KETAN DI KOTA BATUSANGKAR

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 (α = 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

PENGEMBANGAN MODUL PEMBELAJARAN BIOLOGI BERBASIS ANDROID PADA MATERI SISTEM REGULASI UNTUK SISWA SMA/MA

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

The Trends of Biology Education Research from 2000 to 2017: A Content Analysis for the Thesis of Pre-Service Teachers

This study aims to investigate the trend of biological education research (BER) from 2000 to 2017 in the thesis of pre-service biology teachers. This study conducted a series of content analyses of the thesis from two universities. A total 1347 thesis were analyzed in terms of sample, method, design, elements and topics and subject matter. It was found that junior and senior high school were the most popular research sample trends. This study was also found that quantitive, research and development or/and educational design research became the trend of the method most chosen and conducted by preservice biology teachers. This findings were also indicated that descriptive, experimental, and 4-D were design trends chosen by preservice biology teachers. This study was also found that cognitive and media of learning were the research elements are the most chosen and conducted by preservice biology teachers. The next findings showed that system and cell was the most popular of biology topic. This finding also indicated that Digestive System (DS) and Circulatory System (CS) and Features (KF) as the most chosen subject matter trends conducted by preservice teacher

Knowledge Enhancement Among Members of the Women Farmers Group (WFG) through Islamic Science-Based Soil Ecology Education

Farmers' knowledge about soil ecology, which is a key factor in increasing the productivity of agricultural products, needs to be evaluated considering that various counseling efforts to increase agricultural yields have not shown satisfactory results. Farmers still unequally manage farmland, providing excessive chemical fertilizers without regard to soil ecology. The purpose of this education is to evaluate the knowledge of the Women's Farmers Group (WFG) before and after conducting soil ecology education based on Islamic science. The subjects of this education were 15 members of WFG Bunga Padi, Jorong Kawai, Nagari Batu Bulek, Lintau Buo Utara, Tanah Datar, West Sumatra, Indonesia. The community-based research (CBR) approach is used in this educational activity. The stages of educational activities start from socialization, laying the basis of the research and the research design, providing pretests and materials, gathering information and analyzing data on biological factors, capillarity of groundwater, water holding capacity, soil aeration, soil fertility, and soil pH, and the evaluation (post-test). The results show an increase in knowledge and understanding among WFG Bunga Padi members after Islamic science-based soil ecology education. It is hoped that, over time, their mindset in managing farmland will be balanced, with less reliance on chemical fertilizers and more emphasis on soil ecology. As a result, Islamic science-based soil ecology education could have a role in improving farmland and laying the foundation for organic farming
