This paper explored pre-service teachers’ perceptions and knowledge of trigonometric concepts. Convenience sampling technique was used to select a sample of 119 (25 females, 94 males) second year science/mathematics pre-service teachers from two Colleges of Education in the Northern Region of Ghana. Trigonometry Perception Questionnaire (TPQ) and Trigonometry Assessment Test (TAT) were used to collect data on pre-service teachers’ perceptions and conceptual knowledge of trigonometry. Data were coded and keyed into Statistical Package for Service Solutions (SPSS version 20) and analysed using descriptive statistics. The results suggested that pre-service teachers perceived trigonometry as abstract, difficult and boring to learn; and had limited conceptual knowledge of basic trigonometric concepts. Consequently, more that 50% of them were unable to construct and reconstruct the appropriate mental structures for meaningful understanding to enable them respond to important basic trigono...

Monitoring the environment activities is an attractive Abstract— Monitoring the environment activities is an attractive thing for development. That is because the human life would affect the surrounding environtment. There's a lot of research of environment has been done, one of those is the changes of air quality in urban areas. To measure the level of air quality, the data and information from field measurements and laboratory analysis result was needed. This paper review the research result that focus on sensor data processing in multi robot using RAM based neural network. There are 11 pattern input data were processed by temperature data optimization from 250C until 350C, humadity data from 20% until 60% and gas data from 350ppm until 450ppm. The obtained result is from 8 bits and 9 bits become 6 bits in certain level with optimazion percentage is25% and 33,3%. This result effect to the computationan load, it's become more simple, the execution time and data communicatio...

The objectives of this research are to determine the effect of teaching methods and naturalistic intelligence toward knowledge of student’s ecosystem concept. The research was accomplished at public elementry school and applied treatment by level 2x2 design. The samples of the research are the students of grade VI sub district Ciledug Tangerang with 80 samples taken by cluster random sampling. The result of this research showed: (1) Knowledge of the student’s ecosystem concept who are taught through experiential learning method higher than problem solving method, (2) There is interaction effect between teaching method and naturalistic intelligence toward knowledge of student’s ecosystem concept. (3) The student with high naturalistic intelligence, knowledge of student’s ecosystem concept between student who are thaught through problem solving method higher than experiential learning method , (4) The student with low naturalistic intelligence, knowledge of student’s ecosystem concept...

Abstract: Financial Technology is combination of the terms financial services and information technology. As we know Indonesia is one of developing countries and financial industry has shifted to the fast economy technology growth. Broadly to analyze the impact of E-Money and payment instrument card to money transaction with aim to economy growth in Indonesia used data Gross Domestic Product, Total Money Transaction of E-Money and APMK (Payment Instrument Card) 2010 to 2018. The results showed that variabel GDP doesnt had impac from fintech payment for short run but it will have impact in long run.
Keyword : E-Money, APMK, and GDP.

Background: Indonesia as a developing country experiencing epidemiologic transition in which communicable diseases are still main concern in Indonesia, while non-communicable diseases (degenerative) is starting to increase and to be major cause of death. Degenerative diseases are caused by many risk factors including lifestyle, eating habits, smoking, physical inactivity, genetics and other causes. Basic Health Research in 2007 showed the prevalence of the disease in Indonesia among other degenerative joint disease (30.3%), hypertension (29.8%), stroke (0.8%), heart (7.2%), diabetes mellitus (1,1%), and cancer (0.4%). Methods: This research is a descriptive study with a quantitative approach. The study design used was a cross sectional study. The samples in this study were 99 housewives in Ogan Ilir. Sampling technique in this study is a cluster random sampling to select four villages as clusters. The analyses conducted in this study are univariate analysis and correlation tests. Re...

Creativity needs to be done by the teacher in the learning task. With creativity, learning goals would be more easily achieved. Creativity of the teacher in teaching reforms ideas, practices, and educational products. Renewal was about something totally new, combined, or modification of, or the development of new forms of the old to. Classroom management for teachers who do this need modified so that the process learning and teaching fun and students are motivated to learn. Learning component that is directly related to the learning process in the classroom and need to be considered in the management class is primarily instructional materials, media, methods, teacher, student, classroom atmosphere, and arrangement of all components to run. Interaction this raises the learning dynamics. These dynamics can vary its shape and determine the quality and effectiveness of learning. It required creativity in managing classroom teacher in order to target the achievement of goals.
