Abstract

Based on previous research through the questionnaire and test in one of the High School in Bandung, more than 50% of students experienced epistemological learning obstacles on the dynamic fluid material and 66,2% students couldn’t answer the test about Bernoulli’s principle. The aim of this study is to identify the student’s epistemological learning obstacles profile of grade XI Bernoulli’s principle material, based on the respondent’s ability test. Epistemological learning obstacles occur due to limitation of knowledge to a certain concept and it will lead to obstacles in using their knowledge when facing different concept. The method is qualitative descriptive, combined with the historical approach analysis through the respondent’s ability test in the form of three essays covering essential concepts of Bernoulli’s principle, which given to the students in one of the High School in Bandung. The average score 68,27% is the students who experienced obstacles about Bernoulli’s equation in Torricelli’s principle, 95,36% is the students facing obstacles about Bernoulli’s equation in Venturi’s principle, and 87,05% the students obstacles on Bernoulli’s principle in aircraft lift force. The conclusion is the encounter of epistemological learning obstacles on Bernoulli’s principle material, there must be effort to minimize learning obstacles. Keywords: Learning obstacles, Bernoulli's principle, Respondent's Ability Test.

Abstract

Results of a preliminary study conducted by researchers through test and questionnaire obtained 51.5% of students experienced epistemological learning obstacles on the ideal gas equation. Epistemological learning obstacles occur due to one’s limit only to a certain concept. This study aimed to identify the student’s epistemological learning obstacles profile ideal gas equation material based on the analysis tests the ability of respondents. The method used in this study is qualitative descriptive, combined with the historical approach analysis through the respondent’s ability test, in the form of four essays covering essential concept of the ideal gas equation, which given to the students in one High School in Bandung, who had learned about ideal gas equation.The results showed that students experiencing epistemological learning obstacles on the material ideal gas equation, including in identifying problems including process isotermik, interpreting graphs on isobaric process, determine the number of particles that come out on the tank leaked on the concept of equality ideal gas, and apply the concept of mass meetings in equation ideal gas in the case of a hot air balloon. It can be concluded that there are still epistemological learning obstacles on the material ideal gas equation. Keywords: Learning Obstacles, Respondent’s Ability Test, Ideal Gas Equation.

Abstract

In a previous study, which observed and conducted in one of Senior High School in Bandung, using the tests and questionnaires regarding the continuity equation the result shows 60,53% (from the questionnaire) students answer that the continuity equation is difficult to deal with, and 52,71% students (test) students could not answer the test. The aim of this study is to know the learning obstacle of students using the respondent capably test in a continuity equation subject for XI high school students. The learning obstacle that has been studied is the epistemological is the limitation of student to understand the certain content of a particular subject. The method used in this study is a descriptive qualitative method using the history analysis approach in Respondent Capability Test. In this approach, the researchers formed questionnaires essay type in which includes the essential sub-subject from continuity equation. The result of the test shows that students are having epistemological learning obstacles in continuity equation, which include the understanding of ideal fluid observed from current type, incorrect in answering the velocity in the cross-sectional area in question, and could not indicate the volume flow rate given case questionnaire. Keywords: Learning obstacles, Respondent capability Test, Continuity equation.

Abstract

This laboratory research aims to develop a proper room temperature control system in real time and efficient use the concept of simulation. In the first stage experiments were carried out to simulate temperature variations, in a room consisting of 8 point measurements using the LM35 temperature sensor. Then some room temperature conditions are also generated virtually, so that when certain conditions DC motor rotates to move the fan. In the final stages, the temperature is shown in graphical form and displays the temperature distribution waveform in LabVIEW in real-time. Based on the experimental results, the LM35 temperature sensor is able to detect the temperature in real-time in eight different positions. Once the temperature is detected, the LabVIEW software can display temperature variations in three different conditions in real-time, there are comfortable, almost comfortable, and less comfortable. Then, if the temperature detected is in the less comfortable category, the DC motor is moving. Keywords: temperature distribution, LM35 sensor, DC motor, LabVIEW.

Abstract

Diabetes caused 1.5 million deaths in 2012. Higher-than-optimum blood glucose, as the precursor of diabetes, caused an additional 2.2 million deaths. Blood glucose level monitoring is important to mitigate the problem. This inspiring Non Invasive Biomarking Working Group runs the research to measure blood glucose level in non invasive manners, which works using spectrophotometry based methods, and the proper inference engine is needed to recognize the tools spectral responses. This research objective is to compare performance of Multi Formulated Regression Methods (MFR) and Back Propagation Artificial Neural Network (BPANN). This is a comparative experimental study. We let both inference engines to learn same training data and measure its Rooted Means of Squared Error (RMSE). Research done in Material Physics Laboratory, Department of Physics, Bogor Agricultural University, in January 2017. BPANN achieve 6.1372 mg / dl RMSE, as opposed to MFR at 6.0668 mg / dl. The MFR can outperform BPANN in learning accuracy and execution speed, at the expense of far longer training time. We recommend usage of MFR over BPANN for blood glucose level spectral data. Keywords: Multi Formulated Regression, Back Propagation Artificial Neural Network, Non Invasive Blood Glucose Level Measurement Tools, Spectral Responses, Pattern Recognition
