Abstract

This study aims to determine students' cognitive ability and self-efficacy level through diagnostic assessment of business and energetic material in grade VIII SMP Negeri 4 Tambang. This research is a survey research with a quantitative approach. Data was collected by administering test instruments for cognitive diagnostic assessment questions on effort and energy material consisting of 20 multiple-choice question items and self-efficacy questionnaires consisting of 30 statement items. The collected result data is then analyzed using descriptive analysis. Descriptive analysis is used to obtain students' cognitive abilities and self-efficacy in science learning. The results of the descriptive analysis showed that students' cognitive abilities in the cognitive diagnostic assessment of students in class VIII business and energy material of SMP Negeri 4 Tambang were included in the good category with an average score of 51.80. Meanwhile, the results of the self-efficacy analysis of grade VIII students of SMP Negeri 4 Tambang are included in the high category with an average score of 3.32. For this reason, researchers recommend teachers conduct cognitive and non-cognitive diagnostic assessments periodically to determine the level of student abilities and various student conditions.

Abstract

This research aims to describe students' cognitive learning outcomes by applying the scientific approach assisted by KIT hydrostatics and heat in heat material and to determine the differences in students' cognitive learning outcomes between learning using the scientific approach assisted by KIT hydrostatics and conventional learning in heat material at SMAN 4 Pekambaru. The research method used is quasi-experimental with data collection techniques in the form of a posttest. This research uses a sampling technique, namely simple random sampling. The sample in this study included class XI Engineering 1 as the experimental class and class XI Engineering 3 as the control class. The analysis techniques used are descriptive analysis and inferential analysis. The results of research using descriptive analysis showed that the experimental class obtained an average cognitive learning outcome of 83.30 in the very high category, while the control class obtained an average cognitive learning outcome of 70.67 in the high category. The results of inferential analysis in hypothesis testing obtained a value of 0.000 with the condition p < 0.05, which means that there is a significant difference in student cognitive learning outcomes between classes that apply the scientific approach assisted by KIT hydrostatics and heat and classes that apply conventional learning on heat material.

The purpose of this study was to determine the validity and practicality of gas kinetic theory learning devices oriented to 2013 physics curriculum. The place and time of the research was at the Laboratory of Physics Education FKIP University of Riau from June to November 2017. The object of this study was the developed learning devices based on the inquiry approach which includes experimental devices, Learning Plans and Worksheets. This type of research was four D models. Validation was carried out by 3 lecturers of Physics Education Study Program FKIP University of Riau and 2 SMA teachers from Pekanbaru. Limited trial was used to see the practical implementation in class XI IPA 3 of SMAN 4 Pekanbaru. The results of the data analysis obtained that the validity of the gas kinetic theory experimental instrument has very valid category with a logical validation value of 3,47. The validity of the Learning Plan is 3.73 in the very valid category, the validity of the Worksheet is 3.5 whit the very valid category. The practicality of the developed device is 94.1% with a very practical category. The conclusions of the results show that the gas kinetic theory learning devices of High School Oriented Curriculum 2013 were developed valid and high in practicality so that they could be used in physics learning in class XI SMA.

Abstract

Utilization of renewable energy becomes a necessity in the future due to the fossil energy supply continues to decline. In Indonesia, the use of electricity from renewable sources is minimal. The utilization of solar energy in Indonesia is still limited to remote areas or islands. The main problem of electricity in Indonesia, especially in the city of Banda Aceh, is the frequent occurrence of power outages from the state power plant (PLN), especially during peak load time (WBP). Outside of that time, electricity supply exceeds demand. This study aims to utilize solar energy to reduce the electricity consumption of PLN during WBP. The system is designed to divert the power supply from PLN to the solar power plant (PLTS). The results of a survey of 10 A (current limit) customers are used as a reference to calculate PLTS capacity. During WBP, PLTS supplies to the load, beyond that time, PLN will supply the load. The system is designed to store maximum energy beyond the WBP period into the battery, the source of energy is mainly from the PLTS and alternatively from the PLN when the PLTS can not supply the maximum power. Based on battery energy, the system diverts the load supply from PLN when the battery energy is below the recharge limit. In the case of 10 A customers, with the energy requirement during WBP of 4.3 kWh, it requires 12 solar panels (160 Watt maximum power) arranged in parallel. Thus, the system needs three batteries with 150 Ah capacity also assembled in parallel. The implementation results prove that the PLTS can store solar energy to the battery properly, the system also successfully divert the PLTS source to the load at the time of WBP and transfer back to the PLN source when the battery energy is less than the recharge limit.

Abstract

This research aims to determine the increase in student learning gains by implementing the TGT-type cooperative model through Kahoot media on mechanical wave material in class XI SMA N 2 Singingi. The research uses Quasi-Experimental Design type of research with a "post-test only control group design". The instrument used when collecting information was objective test questions on mechanical wave material for class XI high school. The test questions consist of 15 objective questions that refer to 5 cognitive domain indicators. Student learning outcome data is explained both descriptively and inferentially. The learning outcomes of students who applied the TGT model were in a good category, namely 72.8% for the experimental class and 65.9% in the quite good category for the conventional class. So it is concluded that the use of the TGT-type cooperative model assisted by the Kahoot application can improve the cognitive learning outcomes of students in class XI SMA N 2 Singingi.
