Abstract

The ability of teachers to choose learning strategies is an essential and significant concern. In this case, the use of technology in learning. However, not many teachers still use the old strategy, so it is necessary to test with the application of new strategies in the learning process. The intended application of the new strategy is the application of the flipped classroom learning model. The purpose of this study was to determine the differences in student learning outcomes between classes using the flipped classroom learning model and classes using conventional learning models at SMP N 2 Bolangitang Timur. This study used an experimental method with a pretest-posttest control group design. Samples or subjects were taken using the quota sampling technique, namely class VII A and VII B. The data analysis technique consisted of a normality test, homogeneity test, t-test and n-gain test. The results showed that both data were normally distributed and had a homogeneous variance. The t-test analysis at the significant level (α = 0.05) got the results where t0 = 2.24 ta = 2.02 so that H0 was rejected and H1 was accepted. So it can be concluded that there are differences in student learning outcomes between classes that use the flipped classroom learning model and classes that use conventional learning models at SMP N 2 Bolangitang Timur.

Abstract

This study aims to know whether or not there is a difference in the student's cognitive learning outcomes by using a discovery-bassed learning model and problem based learning model on Physics subjects in Static Fluids material. This study applies a quasi-experimental method with a pretest-posttest control group design using two classes. The study site is at SMAN 1 Boliyohuto in the odd semester of 2021. The population in class XI MIA 1, XI MIA 2, XI MIA 3, and XI MIA 4, with the sample is class XI MIA 3 and Class XI MIA 4, totaling 15 students, respectively. This study uses t-test in hypothesis analysis, where the test is based on the minimum completeness criteria for 75. Based on the result of hypothesis testing, the t-count value is 0.604102, and the t-table value is 2.144787 (tcount  ttable), so H0 is rejected, and H1 is accepted. The H0 states that there is a difference in students learning outcomes by applying the experimental discovery-based learning model and the problem-based learning model.Penelitian ini bertujuan untuk mengetahui apakah ada perbedaan hasil belajar kognitif peserta didik dengan menggunakan model pembelajaran discovery dan model pembelajaran berbasis masalah pada pelajaran fisika materi fluida statis.

Abstract

Urbanization is the movement of people from villages to cities, this has caused an increase in population growth in urban areas resulting in increased demand for development which has reduced land for green spaces, green roofs are present as a farming concept amidst limited land in urban areas as well as assisting in passive cooling. The process of photosynthesis must play a role in roof shading. The selection of vegetation in the form of passion fruit vines as a roof covering material can spread up to 24 m, the object of research is a house in a housing complex by comparing two rooms, using a vegetation roof cover and without a vegetation roof cover, based on the results obtained a room with a vegetation roof cover experienced a decrease in temperature as the growth of vines covered the roof, the results obtained were a comparison between the two rooms, namely 0.1℃ in January, 1.1℃ in February and 2.6℃ in March when the peak temperature is during the day.

Abstract

Sample of Arenga Pinnata (AP) fibres, ropes and nets were prepared from AP ropes using traditional tools. The ropes and nets were used as agricultural material such as vertical farming of vines (passion fruit, grape, bitter gourd, and melon) in Gorontalo and Japan. The combination of nets and vines acts as green curtain (GC) which. Could mitigate the thermal energy in outdoor as well as indoor buildings. and tested with the deformation rate of up to the point of rupture. To avoid the failure of ropes and nets on supporting the weight of the vines, the Universal Testing Machine Model WDW-50 were used to determine the ultimate tensile forces. While the physical size of the AP fibres, ropes and nets also being measured to confirm the uniformity of the individual ropes and nets
