Abstract: This study aims to determine whether the CTL learning model is effective against students' mathematical communication disposition and abilities. This research is a quantitative study, the population is students of class X SMA 04 Tebing Tinggi in the academic year 2019/2020. Randomly selected two classes randomly selected namely class X MIA 2 as an experimental class using the CTL learning model and class X MIA 4 as a control class that uses a direct learning model. Data collection methods are the method of observation, tests, and disposition questionnaires. The analysis was performed using the Simple Linear Regression Test. The results of this study indicate that: (1) the influence of CTL on mathematical communication is 91.3%; (2) the effect of CTL on mathematical disposition was 52.7%; (3) communication skills in the control class are better than the experimental class; (4) the mathematical disposition of experimental class students is better than the control class; (5) mathematical disposition has a positive effect on the ability of mathematical communication in the experimental class.Keywords: contextual teaching and learning, mathematical disposition, communication ability

Abstract

The increasingly rapid development of technology and information has enabled transformation in the fields of education and teaching. This is clearly seen in the current curriculum expectations, where one of the expected learning outcomes from elementary school to middle school is that students are expected to have computational thinking skills. For this reason, the aim of this research is to look at students' abilities related to their computational thinking abilities. in solving the problems given. The results of the answers given by students are then analyzed according to the four foundations of computational thinking. This research is descriptive research with a qualitative approach. This research was carried out in the Mathematics Education study program, Universitas Islam Sumatera Utara in the Number Theory course. The sample used was 12 students taking Number Theory courses. The instrument used is a description of 2 questions which are given during the learning process on mathematical induction material. The students' answer sheets were then analyzed to get a picture of students' computational thinking abilities based on the four foundations. The results of this research show that students' computational thinking abilities still need to be improved, such as decomposition abilities which are 41.67% and abstraction abilities which are 58.33%. Overall, students' computational thinking abilities are still in the sufficient ability category.

Abstract

Several areas in Indonesia need more well-developed sanitation infrastructure. Some industries and companies use domestic wastewater disposal systems outside the leading network, a cheaper alternative to centralized systems. The sewage treatment system in these areas typically consists of a septic tank and a medium-scale household wastewater treatment plant. This study aimed to evaluate the effectiveness of SMEC Eye Hospital's liquid waste management after it has been processed through its wastewater treatment system. This experimental research involves managing the liquid waste at SMEC Eye Hospital using an anaerobic-aerobic upflowed biofilter system. The experimental method adheres strictly to a scientific research design. The processed liquid waste is then tested in the laboratory to measure levels of pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), ammonia, oils and fats, and total coliform. The liquid waste from SMEC Eye Hospital was analyzed to determine if the hazardous substances had been reduced or eliminated to meet environmental safety standards. Laboratory tests on the hospital's liquid waste outlet showed that all parameters, including pH, BOD, COD, TSS, ammonia, oil and fat, and total coliform, were within the quality standard limits. To further enhance the environmental safety of the waste, seven steps can be taken to reduce levels of pH, BOD, COD, TSS, ammonia, oil and fat, and total coliform. These measures ensure that the liquid waste from the hospital does not harm the environment.

Abstract

Teachers are provided with the resources they need to incorporate project-based learning into their lesson plans through the Project Based Learning (PjBL) learning paradigm. This study is based on the observation that teachers prefer printed modules over display information because they are more visually appealing. As a result, students do not want to participate in the learning process. There are currently no opportunities for students to practice critical thinking or improve their ability to articulate mathematical ideas in this curriculum. The purpose of this study was to develop a Project Based Learning (PjBL) mathematics learning module and improve students' critical thinking skills at MTs Al-Washliyah Simpang Gambus. The paradigm used to create educational resources is called the 3-D stage of Thiagarajan Development, which stands for Define, Design, and Development. Residents of MTs Al-Washliyah Simpang Gambus became study participants. Students in class VIII A and VIII B, totaling 30 and 26 students, were used as the research sample. based on the results of the validation process carried out by six validators and producing an average score of 4.44 in the very good category. The practicality test results collected through a student response questionnaire obtained an average score of 82.7 with good criteria. With an average N-Gain of 0.71, students' critical thinking skills meet high standards for test results indicating test effectiveness.

Abstract

Penelitian tindakan kelas ini bertujuan untuk meningkatkan keterampilan menulis deskriptif siswa melalui integrasi strategi Think Talk Write (TTW) dan pendekatan Social Emotional Learning (SEL). Penelitian ini dilakukan di Kelas VII UPTD SMP Negeri 6 Kisaran. Penelitian ini dilakukan dalam dua siklus, masing-masing terdiri dari tahap perencanaan, tindakan, observasi, dan refleksi. Temuan menunjukkan bahwa sebelum intervensi, sebagian besar siswa mengalami kesulitan dalam mengorganisasikan ide, kekurangan kosakata, dan memiliki kepercayaan diri yang rendah dalam menulis. Mereka juga menunjukkan keterlibatan emosional dan kolaborasi yang terbatas. Strategi TTW membantu mereka memproses ide langkah demi langkah. Dari berpikir ke berdiskusi, lalu menulis, sementara pendekatan SEL menciptakan lingkungan kelas yang mendukung dan memotivasi. Pada Siklus II, skor rata-rata meningkat dari 60,1 pada tes awal menjadi 79,3. Pada Siklus II, 19 (90,5%) siswa mencapai skor minimal 75, naik dari 2 (9,5%) pada tes awal. Temuan ini menunjukkan bahwa integrasi TTW dan SEL efektif dalam mengatasi tantangan kognitif dan emosional di kelas menulis. Pendekatan ini direkomendasikan untuk meningkatkan kinerja akademis dan kesejahteraan emosional siswa.
