PENERAPAN MODEL MISSOURI MATHEMATICS PROJECT DALAM PEMBELAJARAN MATEMATIKA MATERI SPLDV KELAS VIII SMP N 1 KAKAS
Get PDFIn learning mathematics, students' ability to solve problems affects their learning outcomes. At Smp Negeri 1 Kakas in class VIII, it was found that students' mathematics learning outcomes were still low, especially in the material of the system of linear equations of two variables, this was due to the lack of students' ability to solve mathematical problems. Therefore, the Missouri Mathematics Project model is applied in learning to solve one of the factors causing the above problems. This study aims to see student learning outcomes in learning mathematics material on the system of linear equations of two variables by knowing the average difference in learning outcomes of students who learn using the Missouri Mathematics Project learning model and those who learn using the direct learning model. This research is an experimental research that uses a quantitative approach. The samples in this study were class VIII-D as the experimental class and class VIII-A as the control class at Smp Negeri 1 Kakas in the 2023/2024 academic year. The instrument in this study was an essay-shaped student learning outcomes test. Data collection techniques through posttest results on the material of the system of linear equations of two variables in the experimental class and control class. The results of this study were obtained based on hypothesis testing using t-test statistics obtained at a significance level of 0.05 tcalculated = 2,900 and ttable = 2,010 which means H0 rejected. The conclusion of the research results is that the average learning outcomes of students who learn by using the Missouri Mathematics Project learning model are higher than the average learning outcomes of students who learn by using the direct learning model on the material of the system of linear equations of two variables
PENERAPAN APLIKASI WORDWALL dalam PEMBELAJARAN MATEMATIKA
Get PDFMathematics is one of the compulsory subjects that students take at school. Mathematics is still something that is difficult for students to learn. For this reason, it is important to modify fun and interactive learning activities in the classroom with the use of applications. There are many applications that can be used to support mathematics learning activities. One application that can be used in wordwall. Wordwall is a teaching tool or media that teachers can use to make learning more interesting and interactive in the classroom. This Research was carried out at Cinta Kasih elementary School, Sorong City. Researchers carried out observations and guided teachers in using the wordwall application so that it was applied to grade 5 students. The research method used was quantitative research. This research was carried out with classroom action research planning, namely the researcher supervised the teacher in the learning process in the classroom using the wordwall application. Data collection in the form of data on student activity in the class in group, knowledge, skills. The research result show that students have an average score in the range of 76 – 79, which mean they are good at following the mathematics learning process in classwith the help of the wordwall application

The results indicated a significant positive relationship between students' interest in learning and their mathematics achievement, with a correlation coefficient of 0.7886, which falls under the strong correlation category
PENGARUH PENGGUNAAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING TERHADAP HASIL BELAJAR SISWA PADA MATERI ARITMATIKA SOSIAL DI KELAS VII SMP NEGERI 1 SIAU TIMUR SELATAN
Get PDFThis study aims to determine whether the average learning outcomes of students using the problem based learning model are higher than the average learning outcomes using the direct learning model on social arithmetic material. This study uses a quasi-experimental method, with a Post-test Only Control Group Design research design. The subjects of this study were students in class VII of SMP Negeri 1 Siau Timur Selatan, which consisted of two classes, namely class VIIA as an experimental class using the problem based learning model and class VIIB as a control class using the direct learning model. Data collection was obtained by giving a pest test to both classes after the treatment was carried out. Research statistics were analysed using the t-test, hear the tvalue = 3,349638 > ttable = 2,00665 means H0 is rejected. Thus it can be concluded that the average learning outcomes of students taught with the problem based learning model are higher than average learning outcomes of students taught with the direct learning mode

PEMANFAATAN KARBON AKTIF ECENG GONDOK (EICHHORNIA CRASSIPES) SEBAGAI MATERIAL ELEKTRODA SUPERKAPASITOR DENGAN VARIASI KOSENTRASI ELEKTROLIT Na2SO4
Get PDFThe utilization of renewable energy has become a major focus in an effort to reduce dependence on fossil energy sources and reduce negative impacts on the environment, making it important to increase the use of clean and renewable energy. One of the biggest challenges in the application of renewable energy is efficient and sustainable energy storage. In this case, supercapacitors have proven to be a solution as an efficient and sustainable energy storage device. In this study, water hyacinth biomass material was tested as a supercapacitor electrode which was influenced by variations in Na2SO4 electrolyte, namely 1M, 2M, and 3 M, which produced voltages of 1.037 V, 1.404 V, and 1.647 V respectively and electric currents of 18.56 mA, 23.32 mA, and 32.34 mA. From the results of this study, it was found that the sample with an electrolyte concentration of Na2SO4 3 M had higher voltage and amperage values, which amounted to 1.654 V and 32.34 mA due to the greater number of Na+ and SO42- ions in the electrolyte. So it can be concluded that the variation of Na2SO4 electrolyte concentration of 1 M, 2 M, and 3 M results in an increase in the value of voltage and electric current produced by supercapacitors

PENERAPAN TECHNOLOGY READINESS ACCEPTANCE MODEL (TRAM) DALAM MENGUKUR KESIAPAN DAN PENERIMAAN TEKNOLOGI CASHLESS
Get PDFIn the era of globalization and industrial revolution 4.0, information and communication technology (ICT) has created major changes, especially in financial transactions. This phenomenon has led to the emergence of cashless payment systems as the dominant trend, including in the education sector. Schools in Semarang, as part of their efforts to adapt to such developments, need to shift from traditional payment methods to cashless payment technologies to improve efficiency and convenience. This study aims to understand the acceptance of Cashless technology among school teachers and employees in Semarang using the Technology Readiness Acceptance Model (TRAM) approach. Through Structural Equation Modeling (SEM) analysis, the results show that insecurity plays a major role in influencing perceived ease of use. Although the insecurity factor did not have a significant effect, security also had a positive effect on users' assessment of the usability of Cashless technology
