Abstract

This study is a literature review. The flipped classroom is the latest pedagogical model that has the potential to change the current traditional way of teaching. Flipped classroom emphasizes on learning activities that promote critical thinking and motivation among the students with the assistance of technology. The flipped classroom allows educators to move from ‘the sage on the stage’ to ‘the guide on the side. The basic and simplest form of flipped classroom is students are expected to watch digital resources prior to class. The students are then required to come prepared for class and perform hands-on activities that are related to the digital resources. The digital resources can be in any form such as video, audio or the internet. This allows teachers to spend more time with their students to carry out in class activities and allow immediate response to students’ needs. Student feedback on this pedagogy was generally very positive with many respondents considering it effective and helpful for learning. One of the biggest advantages mentioned by students is that they had the option to watch each video lecture as many times as required to be prepared for class.

Abstract

The C-RTD (Coil-Resistance Temperature Detector) output signal is an analog signal in the form of a direct voltage. This value changes with changes in RTD temperature. This analog signal can be read by users using a multimeter or similar device but does not directly indicate the RTD temperature. In order to obtain RTD temperature values, an additional device is required. In order to have a useful value and practicality, a device that can convert analog signals into values can be read directly by the user. The microcontroller was chosen as a used device. The selected microcontroller system is Arduino Uno because has been coupled with input and output ports so users only need to enter programs related to the system being created. In the other hand Arduino Uno by considering the low cost and practical. For the measurement system, the RTD output signal must be conditioned into a digital signal using the ADC so that it can be processed by the microcontroller. From testing instrument obtained that the system has been able to convert analog RTD signals into digital signals. The range of measurement is -176°C to  0°C with an accuracy of ± 0.20 / mV.

Abstract

This research-based on technological advances that promote the use of technology in learning, on the lack of valid, practical and effective lesson plans, particularly in problem-based learning models that are in line with the 2013 curriculum, and on the use of Lectora Inspire Software in the creation of lesson plans. This study was conducted to develop a product that is a problem-based learning model based on Lectora Inspire software, and that is valid, practical and effective. This type of research is research and development (research and development). The design of this study based on 5 out of 10 phases of Borg and Gall's research design, namely research and collection of initial information, planning, development of original product formats, initial testing and product improvement. The effectiveness test results were rated as very good if the results of the analysis of the responses of teachers and students with an average of 88% and 89.04% as and the increase (n-gain) of student learning outcomes is 0.62 which can be categorized as a moderate increase.

Abstract

The supply of world energy resources is increasingly depleted. The abundance of cow manure and banana peel can cause environmental pollution. It can be used as raw material for biogas because both materials have a high methane gas ratio. This research is an experiment with six variations in the amount of mixture in each experiment. Results of the research on gas pressure and the best biogas production results using 1-litre banana peel substrate and 4-litre cow dung. Data shows that the gas pressure is faster and is greater when the pH of the mixture is acidic 6.2, the mixture is thick green and has a strong odour. Gas pressure on day 20 is obtained by 106421 Pascal. The average value of the results of the validation of the learning resources of the three aspects of an assessment is 82.3%; it shows that the poster can be used as a learning resource.

Abstract

This study aims to analyze the content of Bisphenol A (BPA) on various temperatureandcontact timesbetween the plastic bag and water. For analysis of BPA, a sample made with variations of temperature (± 70°C, ± 80°C, ± 90°C) and contacttime(5 minutes, 10 minutes, 15 minutes) usingnine samples. To determine the concentration of BPA, Lambert-Beer law was employed.According to the analysis of data, the content of BPA on the temperature variation showed that the higher the temperature of the sample, the higher the content of Bisphenol A in the sample. The content of BPA with a variation of contact times stated that with the longer contact time, the higher the content of BPA.

Abstract

Learning achievement is the result achieved by someone after doing the learning process. One of the factors that influence learning achievement is the use of the learning model. This study aims to know the differences in achievement of students learning to use problem-based blended learningmodels and traditional blendedlearning. This study uses a quasi-experimental method of "non-equivalent pretest-posttest control group design." The study population is all class X IPA with a total of 6 classes or 210 people. The sample consists of 3 classes or 107 people.Student learning achievement data were analyzed by descriptive analysis and ANOVA one-way (α= 0.05). The results of this study reveal that there are differences in student achievement due to the learning model. Higher learning achievement was achieved by problem-based blended learningmodels (F = 264.307; α<0.05). The LSD test results showed that the learning achievement of students in the MBLBM group was higher than MBL, the learning achievement of the MBLBM group was higher than that of MPK, and the learning achievement of the MBLBM group was higher than that of MPK.
